RESUMO

BACKGROUND: The Cabrol procedure has undergone various modifications and developments since its invention. However, there is a notable gap in the literature regarding meta-analyses assessing it. METHODS: A systematic review and meta-analysis was conducted to evaluate the effectiveness and long-term outcomes of the Cabrol procedure and its modifications. Pooling was conducted using random effects model. Outcome events were reported as linearized occurrence rates (percentage per patient-year) with 95% confidence intervals. RESULTS: A total of 14 studies involving 833 patients (mean age: 50.8 years; 68.0% male) were included in this meta-analysis. The pooled all-cause early mortality was 9.0% (66 patients), and the combined rate of reoperation due to bleeding was 4.9% (17 patients). During the average 4.4-year follow-up (3,727.3 patient-years), the annual occurrence rates (linearized) for complications were as follows: 3.63% (2.79-4.73) for late mortality, 0.64% (0.35-1.16) for aortic root reoperation, 0.57% (0.25-1.31) for hemorrhage events, 0.66% (0.16-2.74) for thromboembolism, 0.60% (0.29-1.26) for endocarditis, 2.32% (1.04-5.16) for major valve-related adverse events, and 0.58% (0.34-1.00) for Cabrol-related coronary graft complications. CONCLUSION: This systematic review provides evidence that the outcomes of the Cabrol procedure and its modifications are acceptable in terms of mortality, reoperation, anticoagulation, and valve-related complications, especially in Cabrol-related coronary graft complications. Notably, the majority of Cabrol procedures were performed in reoperations and complex cases. Furthermore, the design and anastomosis of the Dacron interposition graft for coronary reimplantation, considering natural anatomy and physiological hemodynamics, may promise future advancements in this field.

RESUMO

ABSTRACT: To investigate whether plasma concentrations of S100ß protein, neuron-specific enolase (NSE), and neuroglobin (NGB) correlate with early postoperative cognitive dysfunction (POCD) in patients undergoing total arch replacement.This prospective study analyzed 40 patients who underwent total arch replacement combined with stented elephant trunk implantation at our hospital between March 2017 and January 2019. Cognitive function was assessed using the Mini-mental State Examination (MMSE) preoperatively, on the day after extubation and on day 7 after surgery. Plasma levels of S100ß, NSE, and NGB POCD were assayed preoperatively and at 1, 6, and 24 hours after cardiopulmonary bypass. POCD was defined as a decrease of at least 1 unit in the MMSE score from before surgery until day 7, and patients were stratified into those who experienced POCD or not. The 2 groups were compared in clinicodemographic characteristics and plasma levels of the 3 proteins.Plasma levels of all 3 biomarkers increased significantly during and after cardiopulmonary bypass. Levels of S100ß and NSE, but not NGB, were significantly higher in the 15 patients who showed POCD than in the remainder who did not. For prediction of early POCD, S100ß showed an area under the receiver operating characteristic curve (AUC) of 0.71 (95% confidence interval [CI] 0.55-0.87), sensitivity of 48%, and specificity of 87%. The corresponding values for NSE were 0.77 (95%CI 0.60-0.94), 92%, and 67%. Together, S100ß and NSE showed an AUC of 0.81 (95%CI 0.66-0.96), sensitivity of 73%, and specificity of 80%. NGB did not significantly predict early POCD (AUC 0.62, 95%CI 0.43-0.80).Plasma S100ß protein and NSE, but not NGB, may help predict early POCD after total arch replacement.

RESUMO

BACKGROUND The protein NKX2-5 affects mammalian heart development. In mice, the disruption of Nkx2-5 has been associated with arrhythmias, abnormal myocardial contraction, abnormal cardiac morphogenesis, and death. However, the details of the mechanisms are unclear. This study was designed to investigate them. MATERIAL AND METHODS Rat cardiomyocytes from the H9c2 cell line were used in our study. First, we knocked down Nkx2-5 in the H9c2 cells and then validated consequent changes in cell proliferation and migration. We then used RNA sequencing to determine the changes in transcripts. Finally, we validated these results by quantitative reverse transcription-polymerase chain reaction. RESULTS We confirmed that Nkx2-5 regulates the proliferation and migration of H9c2 cells. In our experiments, Nkx2-5 regulated the expression of genes related to proliferation, migration, heart development, and disease. Based on bioinformatics analysis, knockdown of Nkx2-5 caused differential expression of genes involved in cardiac development, calcium ion-related biological activity, the transforming growth factor (TGF)-ß signaling pathway, pathways related to heart diseases, the MAPK signaling pathway, and other biological processes and signaling pathways. CONCLUSIONS Nkx2-5 may regulate proliferation and migration of the H9c2 cells through the genes Tgfb-2, Bmp10, Id2, Wt1, Hey1, and Cacna1g; rno-miR-1-3p; the TGF­ß signaling pathway; the MAPK signaling pathway; as well as other genes and pathways.
