RESUMO
This study aimed to compare the long-term clinical outcomes and costs between using either transesophageal echocardiography (TEE) or X-ray fluoroscopy for Percutaneous atrial septal defect (ASD) closure in children. An analysis was conducted on clinical data from children undergoing TEE-guided (n = 168) and X-ray-guided (n = 139) percutaneous ASD closure. Demographic characteristics, technical indices, acute complications, follow-up outcomes, and costs were compared between the groups. The results are that TEE-guided closure demonstrated shorter surgical times (20.3 ± 7.6 min vs. 32.8 ± 7.9 min, P < 0.001) and lower procedural costs ($3093.3 ± 451.5 vs. $3589.1 ± 219.4, P < 0.001) compared to X-ray guidance. Initial successful closure rates were similar between the groups (TEE: 98.2%, XR: 97.1%, P = 0.691). TEE guidance also resulted in fewer acute complications and reduced radiation exposure. TEE-guided percutaneous ASD closure offers advantages in terms of shorter surgical times, lower procedural costs, and reduced radiation exposure compared to X-ray guidance. These findings support the preference for TEE guidance in pediatric ASD closure procedures, with potential implications for improving patient outcomes and reducing healthcare costs.
RESUMO
IL-4, an immunoregulatory cytokine, plays a role in various cellular pathways and is known to regulate M2 macrophage polarization. Numerous studies have suggested that promoting the polarization of macrophages toward the M2 phenotype is beneficial for myocardial infarction (MI) recovery. However, whether IL-4 can achieve therapeutic effects in MI by regulating M2 macrophage polarization remains unclear. In this study, the authors observed that IL-4 increased the proportion of M2 macrophages in the ischemic myocardium compared to the PBS group. Additionally, IL-4 reduced the infiltration of inflammatory cells and the expression of proinflammatory-related proteins, while enhancing the expression of genes associated with tissue repair. Furthermore, IL-4 facilitated the recovery of cardiac function and reduced fibrosis in the post-MI phase. Importantly, when macrophages were depleted, the therapeutic benefits of IL-4 mentioned above were attenuated. These findings provide evidence for the effectiveness of IL-4 in treating MI through the regulation of M2 macrophage polarization, thereby encouraging further development of this therapeutic approach.
RESUMO
OBJECTIVE: This study was designed to investigate the risk factors of postoperative acute kidney injury (AKI) in patients with complex congenital heart disease (CHD) and the significance of early detection of serum transcription factor Nkx2.5. METHODS: A total of 121 CHD patients admitted to the Shengli Clinical Medical College of Fujian Medical University were selected as study participants, among whom 69 patients with AKI after cardiac surgery were set as the research group (RG), and the rest of the 52 patients without AKI were set as the control group (CG). Cardiopulmonary bypass (CPB) duration, aortic occlusion time, postoperative creatinine (Cr) level and mechanical ventilation (MV) time were compared between the two groups. The expression and clinical significance of Nkx2.5 in the two groups were detected. Intensive Care Unit (ICU) residence time and total hospital stay were compared, and the risk factors were analyzed. RESULTS: The RG presented remarkably longer CPB duration and aortic occlusion time, evidently higher postoperative Cr level and longer MV time, and observably lower Nkx2.5 level in comparison to the CG (all P<0.05). According to the analysis of receiver operating characteristic (ROC) curves, Nkx2.5 displayed a favorable diagnostic value in predicting the occurrence of CHD complicated with AKI. ICU residence time and total hospital stay were longer in the RG than in the CG (P<0.05). CPB time and aortic occlusion time were independent risk factors for AKI in CHD patients, while surgical methods and Nkx2.5 detection were independent protective factors (P<0.05). CONCLUSIONS: CPB time, aortic occlusion time and surgical methods, as well as Nkx2.5 detection are independent factors affecting AKI in patients with CHD. Early detection of serum transcription factor Nkx2.5 is of particular importance for clinical diagnosis of CHD patients complicated with AKI.
RESUMO
BACKGROUND: This study compared the perioperative and follow-up period data of patients who underwent redo tricuspid valve replacements performed via thoracoscopic surgery or median sternotomy. The purpose was to evaluate the feasibility, safety, and surgical outcomes of redo tricuspid valve replacement via uni-port thoracoscopic surgery. METHODS: Forty-nine patients with severe tricuspid valve regurgitation after left-side valve replacement underwent redo tricuspid valve replacements in our hospital from April 2012 to September 2019. Twenty-six patients underwent uni-port total thoracoscopy surgery, whereas 23 patients had the surgery performed via median sternotomy. We collected perioperative and 3- to 36-month postoperative data. RESULTS: No deaths occurred in the intraoperative period. Time of cardiopulmonary bypass in the study group significantly was longer than that in the control group (P < .05), but the operative times in the study and control groups were not significantly different. Thoracic drainage, length of ICU stay, postoperative hospital stay, and complication rates in the study group were significantly different from those in the control group (P < .05). Throughout the follow-up period, uni-port total thoracoscopic TVR was not inferior to traditional surgery with respect to cardiac function and recurrence of tricuspid valve regurgitation. CONCLUSIONS: Uni-port total thoracoscopic tricuspid valve replacement is safe, feasible and effective, and that can be considered as a primary treatment strategy for patients with severe TR after previous left-sided valve procedure.
