This study investigated whether the respiratory variation of velocity time integral (ΔVTI) and peak velocity (ΔVpeak) of left ventricular outflow tract (LVOT) could predict hypotension after induction of general anesthesia in elderly patients. Methods : 120 elderly patients undergoing selective operation under general anesthesia were enrolled in this study. ΔVTI and ΔVpeak of LVOT were measured by transthoracic echocardiography before induction of general anesthesia. After induction, mean arterial pressure (MAP) was recorded every 1 min for 15 min. Hypotension was defined as a decrease of more than 30% in MAP at baseline or MAP below 65 mmHg from the start of induction. Receiver operating characteristic curves with gray zone and multivariate logistic regression analysis were used to assess the ability of ΔVTI and ΔVpeak of LVOT to predict hypotension after induction of general anesthesia. Results : Hypotension occurred in 64 (53.3%) patients after induction of general anesthesia. The area under receiver operating characteristic curves (AUC) for δVpeak of LVOT to predict hypotension after induction of general anesthesia was 0.811, and the optimal cutoff value was 13.1% with a gray zone of 9.9% to 13.8%, including 45.0% of patients. The AUC for ΔVTI of LVOT was 0.890, and the optimal cutoff value was 13.8% with a gray zone of 11.1% to 13.9%, including 25.8% of patients. After adjusting for confounders, ΔVTI (Odds ratio = 2.24) and ΔVpeak (Odds ratio = 2.09) of LVOT were two significant independent predictors of hypotension after induction of general anesthesia. Conclusions : ΔVTI of LVOT was a reliable predictor of hypotension after the induction of general anesthesia in elderly patients. ΔVpeak of LVOT should be used cautiously to predict hypotension after induction of general anesthesia due to nearly half of elderly patients in the gray zone.

The aim of this study was to reveal the choline metabolism genes (CMGs) associated with SIC and to provide effective targets for the treatment of SIC . Methods: Through a comprehensive analysis of the microarray dataset GSE79962 (comprising 20 SIC patients and 11 healthy controls) from the GEO database, suspected co-expression modules and differentially expressed genes (DEGs) in SIC were identified. Hub CMGs were obtained by intersecting choline metabolism database with DEGs and key model genes. Afterward, hub CMGs most significantly involved in prognosis were further analyzed for the verification of major pathways of enrichment analysis. Finally, the expression of hub CMGs in in vivo and in vitro SIC model was verified by immunohistochemistry staining and quantitative real-time polymerase chain reaction analysis (qPCR). Results: Weighted gene co-expression network analysis identified 1 hub gene panel and 3,867 hub genes, which were intersected with DEGs and CMGs to obtain the same 3 hub CMGs:HIF-1α, DGKD, and PIK3R1. Only HIF-1α shows significant association with mortality ( P = 0.009). Subsequent differential analysis based on the high and low HIF-1α expression yielded 63 DEGs and then they were uploaded into Cytoscape software to construct a protein-protein interaction network and 6 hub genes with the highest priority were obtained (CISH, THBS1, IMP1, MYC, SOCS3, and VCAN). Finally, a multifactorial COX analysis revealed a significant correlation between HIF-1α and survival in SIC patients, which was further validated by in vitro and in vivo experiments.

Among its main pathologic mechanisms is the rapid and intense inflammatory response. Ozone is a naturally occurring compound and is known for its properties as an oxidizing agent. Ozone therapy is the clinical application of a mixture of ozone (O 3 ) and oxygen, used within nontoxic, safe concentrations. It could be used for the treatment of several diseases. Ozone rectal insufflation (O 3 -RI) is a treatment in which medical O 3 is introduced into the rectum to treat and prevent disease. Although O 3 therapy exerts anti-inflammatory effects, its function in ALI remains unclear. The aim of this study was to preliminarily investigate the role and function of O 3 -RI in ALI. Methods: A mouse model of ALI was established by intratracheal administration of LPS. O 3 -RI was administered 4 h following the modeling procedure. Lung histopathology, lung wet/dry ratio, protein content in bronchoalveolar lavage fluid (BALF), and myeloperoxidase activity in lung tissues, as well as the number of inflammatory cells and inflammatory cytokines in BALF, were assessed. The expression levels of NOD-like receptor thermal protein domain associated protein (NLRP3)/apoptosis-associated speck-like protein (ASC)/caspase-1 axis-related proteins in lung tissues were examined by real-time fluorescence quantitative polymerase chain reaction and Western blotting. Results: Ozone therapy reduced the wet/dry ratio of lung tissue and total protein content in BALF and attenuated lung edema and microvascular leakage in ALI mice. Ozone therapy reduced the myeloperoxidase content in the lung tissue, the number of inflammatory cells, and the content of inflammatory cytokines in BALF and attenuated lung tissue inflammation in mice with ALI. Ozone therapy ameliorated lung tissue morphological damage in ALI mice. Ozone therapy downregulated the expression of NLRP3/ASC/caspase-1 axis-related proteins.

The aim of this study was to investigate the impact of changes in platelet trajectories on the clinical prognosis of sepsis. Methods: This study was a retrospective analysis using data from the Medical Information Mart for Intensive Care IV database. Patients with sepsis were identified from the database, and their platelet trajectories were categorized into four distinct models based on the changes in platelet counts over a period of 14 days after diagnosis of sepsis. The effect of these trajectories on patient prognosis was subsequently evaluated. Results: A total of 15,250 patients with sepsis were included to construct a model, and the following four distinct platelet count trajectories were identified: normal platelet levels (phenotype 1); persistently low platelet levels (phenotype 2); gradually increasing platelet levels exceeding the normal range (phenotype 3); and consistently significantly elevated platelet levels (phenotype 4). Statistically significant differences were found in the 28-day mortality, in-hospital mortality, and 90-day mortality among the four phenotypes. Multivariate regression analysis showed that compared to the group with normal platelet levels (phenotype 1), the group with persistently low platelet levels (phenotype 2) had higher in-hospital mortality (odds ratio [OR] = 1.34, 95% confidence interval [CI]: 1.16-1.54), 28-day mortality (OR = 1.69, 95% CI: 1.47-1.94), and 90-day mortality (OR = 1.50, 95% CI: 1.32-1.69). There was no difference in in-hospital mortality between phenotypes 3 and 4 compared to phenotype 1, although phenotype 4 showed an increase in 28-day mortality ( P < 0.05), and phenotype 3 showed a decreasing trend in 90-day mortality ( P < 0.05). The results of inverse probability weighting adjusted by regression were basically consistent with the above findings, except that there was no statistical difference in 28-day mortality between phenotype 4 and phenotype 1. In the subgroups based on age, weight, and antiplatelet drugs or therapies, there was an interaction between platelet levels and these factors. Conclusions: In patients with sepsis, a decrease in platelet count is associated with increased mortality, while a moderate increase in platelet count can reduce 90-day mortality.

Methods: Trauma patients aged 18 and older, admitted to two Level 1 trauma centers between 2016 and 2021, who received at least one unit of emergency-release blood products were identified.
