Abstract
Background Ischemia and reperfusion injury (IRI) is an ineluctable immune-related pathophysiological process during organ transplantation, which not only causes a shortage of donor organs, but also has long-term and short-term negative consequences on patients. Severe IRI-induced cell death leads to the release of endogenous substances, which bind specifically to receptors on immune cells to initiate an immune response. Although innate and adaptive immunity have been discovered to play essential roles in IRI in the context of organ transplantation, the pathway and precise involvement of the immune response at various stages has not yet to be elucidated. Methods We combined “IRI” and “organ transplantation” with keywords, respectively such as immune cells, danger signal molecules, macrophages, neutrophils, natural killer cells, complement cascade, T cells or B cells in PubMed and the Web of Science to search for relevant literatures. Conclusion Comprehension of the immune mechanisms involved in organ transplantation is promising for the treatment of IRI, this review summarizes the similarities and differences in both innate and adaptive immunity and advancements in the immune response associated with IRI during diverse organ transplantation.

Differences in routes of guiding catheters for left coronary artery according to access sites assessed by the combined angiography-computed tomography system. Cardiovasc Interv Ther 2020; 36:298-306. [PMID: 32537725 DOI: 10.1007/s12928-020-00681-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2020] [Accepted: 06/08/2020] [Indexed: 10/24/2022]
Abstract
Differences in guiding catheters (GCs) manipulations and selections among different access sites are currently unclear. We examined the differences in the routes of GCs for the left coronary artery (LCA) among the right radial, left radial, and femoral approaches. We used a combined angiography-computed tomography (CT) system that enabled to perform CT scans during percutaneous coronary intervention (PCI). We enrolled 88 patients who underwent CT scans during LCA PCI or percutaneous transluminal septal myocardial ablation. To evaluate the route of GCs, we analyzed the positions of the catheter's contact point on the contralateral aortic wall to the LCA ostium, which were expressed by the angle formed by the vertical line and the diagonal line from the GC shaft to the center of the aorta. The procedures were performed via the right radial in 47 cases, left radial in 20, and femoral approach in 21. The positions of the catheter's contact point were significantly different depending on the approaches (interquartile range - 3.7 [- 14.3 to 7.8], - 46.5 [- 76.9 to - 9.3], and - 30.7 [- 39.4 to - 22.4] degrees, respectively; p < 0.001). Multivariate analysis demonstrated that access sites and LCA ostium locations had significant impacts on the positions of the catheter's contact point. The routes of LCA GCs were different among the right radial, left radial, and femoral approaches.

[PMID: 32395511 PMCID: PMC7210190 DOI: 10.21037/atm.2020.03.99] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Indexed: 01/06/2023]
Abstract
Background To perform a retrospective analysis of 47 cases of pediatric heart transplantation in a single Chinese center. Methods The study included 47 cases of heart transplantation under 18 years old, completed between Sep 1st, 2008 and Dec 31st, 2018. We carried out statistical analysis of the clinical features of the donors and recipients, perioperative information, postoperative complications and short- and mid-term survival. Results The study included 24 males and 23 females. The average age on transplantation was 10.34±4.80 years (minimum 3 months, median 11.00 years). Preoperative diagnosis included 36 cases of cardiomyopathy, 9 cases of complex congenital heart disease (CHD), and 2 cases of cardiac tumor. Four patients received cardiac surgery before. The donors’ average age was 20.89±11.84 years, including 19 donors under 18 years old and 28 donors over 18 years old. The mean donor/recipient body weight ratio was 1.58±0.58. The mean duration of intraoperative cardiopulmonary bypass (CPB) was 119.00±53.47 minutes, in which the mean CPB-assist time was 79.71±48.21 minutes. The average duration of postoperative mechanical ventilation was 32.00 (18.50–54.00) hours, and the average intensive care unit (ICU) stay was 7.00 (4.94–11.28) days. Postoperative complications occurred in 20 cases (42.55%). The 1-year, 3-year, and 5-year survival rate after operation was 95.74%, 93.01%, and 93.01% respectively. Conclusions Heart transplantation is an effective means for end-stage heart disease in children. The clinical outcome of pediatric heart transplantation in our center is satisfactory, with low incidence of postoperative complications and high short- and mid-term survival rates.
