Predictive Value of CFIm25 Expression in Peripheral Blood Monocytes for Coronary Atherosclerosis.

Background: Cleavage factor Im25 (CFIm25) regulates cell function by affecting mRNA editing processes and plays diverse roles in various diseases. Studies have found that peripheral blood monocytes are valuable in diagnosing and prognosing coronary atherosclerosis. However, no studies have examined the predictive value of CFIm25 expression in peripheral blood monocytes for coronary atherosclerosis. Methods and Results: We collected the coronary angiography results of 267 patients and calculated the Gensini score to evaluate their degree of coronary atherosclerosis. We isolated peripheral blood monocytes and detected CFIm25 RNA expression. Based on their Gensini score, we divided the patients into negative (0, n = 46), mild lesion (≤ 8, n = 71), moderate lesion (8-23, n = 76), and severe lesion (≥ 23, n = 74) groups. Results showed that CFIm25 expression correlated negatively with the Gensini score and the number of involved coronary vessels. Univariate and multivariate binary logistic regression analyses showed that CFIm25 expression in peripheral blood monocytes was a protective factor for severe lesions, ≥ 50% stenosis, and three-vessel lesions. The areas under the receiver operating characteristic curve of CFIm25 expression for predicting lesions, severe lesions, ≥50% stenosis, and three-vessel lesions were 0.743, 0.735, 0.791, and 0.736, respectively. Conclusions: CFIm25 expression in peripheral blood monocytes correlates negatively with the degree of coronary atherosclerosis and helps predict the severity and number of coronary artery lesions.

T-cell Immunoglobulin and Mucin Domain 3 in Circulating Monocytes as a Novel Biomarker for Coronary Artery Disease.

The diagnostic role of T-cell immunoglobulin and mucin domain 3 (Tim-3) expression levels in circulating monocytes in coronary artery disease (CAD) remains to be determined. Here, we enrolled of 265 patients and isolated circulating monocytes from the blood of all participants. We found that the Tim-3 expression levels in monocytes were lower in CAD patients than in the control group. Spearman correlation analysis verified that the Tim-3 levels in monocytes were negatively correlated with the Gensini score and the number of coronary vessels. Multivariate logistic regression analysis showed that the Tim-3 levels in circulating monocytes were negatively correlated with CAD, severe CAD, and three-vessel CAD. The ROC curve showed that Tim-3 possessed high diagnostic value for CAD, severe CAD, and three-vessel CAD, with CAD prediction being the most significant of these values. In conclusion, Tim-3 in circulating monocytes is a novel biomarker for CAD. T-cell immunoglobulin and mucin domain 3 (Tim-3) in circulating monocytes as a novel biomarker for coronary artery disease.

Survival and analysis of prognostic factors for primary malignant cardiac tumors based on the SEER database.

PURPOSE: The purpose of this study was to use the Surveillance, Epidemiology, and End Results (SEER) database to evaluate the survival rate of primary malignant cardiac tumors (PMCTs), assess the risk factors affecting survival, and calculate the number of PMCT cases in recent years. METHODS: SEER 22 registries were used to calculate the number of cases PMCT. Data on age, sex, race, marital status, tumor size, the American Joint Committee on Cancer (AJCC) stage, lymph node involvement, metastasis, treatment, and survival were collected to analyze the survival and prognostic factors of SEER 17 registries. Using the Kaplan-Meier estimation method, a survival curve was obtained according to the influencing factors, and a multivariable Cox regression model was established. RESULTS: In recent years, the average annual number of PMCT cases was 20.56 ± 7.12, significantly higher than the average before 2004 (P = 0.015; 95% CI 1.14-8.98). The 1-, 3-, and 5-year survival rates were 45.6%, 18.8%, and 11.2%, respectively. Multivariate analysis revealed that age (risk ratio [HR], 2.047; 95% CI 1.381-3.034), AJCC stage III (HR, 1.786; 95% CI 1.123-2.839), AJCC staging with distant metastasis (HR, 2.666; 95% CI 1.509-4.709), no chemotherapy (HR, 2.011; 95% CI 1.561-2.590), and tumor size larger than 99 mm (HR, 1.766; 95% CI 1.132-2.756) were independent risk factors for poor prognosis. Only age over 76 years and distant metastasis were independent risk factors for prognosis in the chemotherapy group. CONCLUSION: In recent years, the annual number of patients with PMCT has increased significantly. Due to developments in chemotherapy, we should re-evaluate the traditional tumor staging and prognostic risk indicators to improve clinical applications.

Sacubitril/valsartan attenuates myocardial ischemia/reperfusion injury via inhibition of the GSK3ß/NF-κB pathway in cardiomyocytes.

In ischemia/reperfusion (I/R) injury, both inflammation and apoptosis play a vital role, and the inhibition of excessive inflammation and apoptosis show substantial clinical potential in the treatment of I/R disease. The role of sacubitril/valsartan (SAC/VAL)-a first-in-class angiotensin receptor-neprilysin inhibitor (ARNI)-in inflammation regulation and apoptosis in the context of I/R injury needs to be further explored. In this study, we investigate the short- and long-term effects of SAC/VAL administration in treating adult murine I/R injury both in vivo and in vitro. Our results verified that the application of SAC/VAL could reduce infarct size and suppress apoptosis and the inflammatory response in the acute phase post I/R. Long-term application of SAC/VAL for four weeks significantly improved ventricular function and reversed pathological ventricular remodeling. Mechanistically, SAC/VAL treatment induces the inhibition of the GSK3ß-mediated NF-κB pathway through synergistically blocking angiotensin 1 receptor (AT1R) and activating natriuretic peptide receptor (NPR). In summary, we reported the therapeutic role of SAC/VAL in regulating the GSK3ß/NF-κB signaling pathway to suppress the inflammatory response and apoptosis, thereby reducing cardiac dysfunction and remodeling post I/R.

Outcomes of atrial fibrillation in patients with COVID-19 pneumonia: A systematic review and meta-analysis.

BACKGROUND: Recently, emerging evidence has suggested that atrial fibrillation (AF) has an epidemiological correlation with coronavirus disease 2019 (COVID-19). However, the clinical outcomes of AF in COVID-19 remain inconsistent and inconclusive. The aim of this study was to provide a comprehensive description of the impact of AF on the prognosis of patients with COVID-19 pneumonia. METHODS: Three electronic databases (PubMed, Embase, and Web of Science) were searched for eligible studies as of March 1, 2021. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were used to evaluate the associations between AF (preexisting and new-onset) and in-hospital mortality, post-discharge mortality, and ventilator use. RESULTS: A total of 36 individual studies were incorporated into our meta-analysis. The combined results revealed that preexisting AF was associated with increased in-hospital mortality (pooled OR: 2.07; 95% CI: 1.60-2.67; p < 0.001), post-discharge mortality (pooled OR: 2.69; 95% CI: 1.24-5.83; p < 0.05), and ventilator utilization (pooled OR: 4.53; 95% CI: 1.33-15.38; p < 0.05) in patients with COVID-19. In addition, our data demonstrated that new-onset AF during severe acute respiratory syndrome coronavirus 2 infection was significantly correlated with increased mortality (pooled OR: 2.38; 95% CI: 2.04-2.77; p < 0.001). CONCLUSIONS: The presence of AF is correlated with adverse outcomes in patients with COVID-19 pneumonia, which deserves increased attention and should be managed appropriately to prevent adverse outcomes.

Outcomes of new-onset atrial fibrillation in patients with sepsis: A systematic review and meta-analysis of 225,841 patients.

BACKGROUND: The outcomes of new-onset atrial fibrillation (AF) during sepsis are inconsistent and inconclusive. This meta-analysis aims to provide a comprehensive description of the impact of new-onset AF on the prognosis of sepsis. METHODS: Three electronic databases (PubMed, Embase, and the Cochrane Library) were searched for relevant studies. Meta-analysis was performed using odds ratios (OR) and 95% confidence intervals (CI) as effect measures. RESULTS: A total of 225,841 patients from 13 individual studies were incorporated to the meta-analysis. The summary results revealed that new-onset AF during sepsis was associated with increased odds of in-hospital mortality (pooled OR: 2.09; 95% CI: 1.53-2.86; p < 001), post-discharge mortality (pooled OR: 2.44; 95% CI: 1.81-3.29; p < .001), and stroke (pooled OR:1.88; 95% CI: 1.13-3.14; p < .05). Results also indicated that the incidence of new-onset AF varied from 1.9% for mild sepsis to 46.0% for septic shock. Furthermore, compared to those without AF, people with new-onset AF had longer ICU and hospital stays, as well as a higher recurrence of AF. CONCLUSIONS: New-onset AF is frequently associated with adverse outcomes in patients with sepsis. This is a clinical issue that warrants more attention and should be managed appropriately to prevent poor prognosis.
