Meta-Analysis Review
Outcomes Following Use of Bovine Pericardium (Xenoprosthetic) Grafts for Reconstruction of Mycotic Aortic Aneurysms and Infected Aortic Grafts: A Systematic Review and Meta-Analysis.
BACKGROUND
Infected aortic grafts and mycotic aneurysms represent one of the most complex challenges faced by vascular surgeons. Treatment has progressed from extra-anatomical bypass to in situ reconstruction. Additionally, bovine pericardium reconstruction (BPR) has increased, due to accessibility and reduced lower limb morbidity. There remains, however, limited evidence for its use. The aim is to pool all known data to understand outcomes following BPR of mycotic aneurysms or infected vascular grafts.
METHODS
A systematic review was conducted in November 2021 with subsequent computerized meta-analysis of the pooled results and a final search in March 2022. Three databases, Excerpta Medica dataBASE (EMBASE), Cumulative Index of Nursing and Allied Health Literature (CINAHL), and National Institutes of Health PubMed (PubMed), were searched for the search term "(bovine OR xenoprosthetic) AND (aneurysm)", according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.
RESULTS
From 9 studies, there were 133 patients: 67% graft infections and 33% mycotic aneurysms. Fifty-seven percent of reconstructions were in the abdominal aorta and 33% were in the thoracic aorta. One hundred fifty-eight pathogens were identified, including Staphylococcus aureus (23%), Candida albicans (13%), and Escherichia coli (13%). In 12%, no microorganisms were identified. Thirty-day mortality was 19.14% (CI 10.83-28.71), late mortality was 19.08% (confidence interval [CI] 7.76-32.83), and overall mortality was 40.20% (CI 29.82-50.97). One patient died intraoperatively. There were a total of 151 in-hospital complications after 30 days postoperation. Common complications were acute renal failure (17%), pneumonia (14%), delirium (12%), respiratory insufficiency (11%) and renal insufficiency (7%). Lower limb ischemia was low, occurring in 5.66% (CI 0.54-13.82) of patients. Loss of graft patency leading to reintervention occurred in 1.20% (CI 0.00-7.71) of the grafts. Reinfection rate was 0.00% (CI 0.00-1.21).
CONCLUSIONS
This meta-analysis highlights low reinfection and high graft patency using BPR with medium-length follow-up; however, there remain limited long-term and comparative data regarding options for aortic reconstruction. As expected in this complex cohort, the complication rate and 30-day mortality remain high.

Review
BACKGROUND
Perfect heart valve prostheses have optimized hemodynamics, reduced surgical morbidity, long-lasting durability, and extended patient survival with greater quality of life. Mechanical valves are recommended; however, young children may need anticoagulant medication for life. In this study, we looked at the success rate and viability of aortic valve neocuspidization (AVNeo) surgery for a variety of aortic disorders.
METHODS
A methodical search strategy was used to fully evaluate the AVNeo results. Boolean operators were used to combine important words like 'Ozaki Procedure,' 'Aortic Valve Neocuspidization,' 'AVNeo,' and associated terms. Reputable databases such as PubMed, MEDLINE, Embase, Web of Science, and Scopus were the focus of our search. Study quality was assessed using a critical evaluation created with the Critical Appraisal Skills Programme tool.
RESULTS
The findings are summarized in the 'Results' section that contains descriptive and critical analysis, ramifications, and explanations. According to research, AVNeo improved valve function and had few side effects. Aortic valve neocuspidization has a lower mean pressure gradient and a larger mean efficient orifice area than Trifecta. Aortic valve neocuspidization surgery reduces aortic valve regurgitation and pressure gradients. Postoperative echocardiograms indicated a decrease in peak and a rise in mean pressure gradient.
CONCLUSION
The Ozaki method restores a healthy laminar flow pattern while preventing bivalvular disease. Ozaki procedure should be explored for valve repair in infants with truncal valve and congenital aortic disease. Aortic valve tricuspidization with glutaraldehyde-treated autologous pericardium results in considerable effective orifice area, modest pressure gradients, and little regurgitation.

Review
BACKGROUND
In 2014, Ozaki introduced the neo-cuspidation (Ozaki procedure), a new valve from the pericardium, to reduce or even prevent the risk of chronic autoimmune inflammation and subsequent rejection or valve degeneration. Thus, the authors aimed to assess the safety and efficacy of the Ozaki technique in treating aortic valve diseases.
MATERIALS AND METHODS
A comprehensive search was performed via PubMed, the Cochrane Library, Scopus, and the Web of Science up to 20 February 2022. Random-effects meta-analysis models were employed to estimate the pooled mean and SD or event to the total of the Ozaki procedure. Relevant records were retrieved and analyzed by OpenMeta analyst software.
RESULTS
A total of 2863 patients from 21 studies were finally included in our analysis. Ac. Ozaki technique showed statistical significance in terms of mean cardiopulmonary bypass time of 148 mins (95% CI 144-152.2, <0.001), mean aortic cross-clamp time of 112.46 mins (95% CI 105.116, 119.823, <0.001), reoperation with a low risk of 0.011 (95% CI 0.005, 0.016, =0.047), conversion to aortic valve replacement with a low risk of 0.004 (95% CI -0.001, 0.008, =0.392), finally ICU stay (days) and hospital length of stay (days) with a mean of 2.061 days (95% CI 1.535, 2.587, <0.001) and 8.159 days (95% CI 7.183-9.855, <0.001), respectively.
CONCLUSION
The Ozaki procedure provides a safe surgical technique with low mean cardiopulmonary bypass time and aortic cross-clamp time; moreover, a mean of 2-day-postoperative hospital stay was observed with the Ozaki procedure with a low risk of conversion to aortic valve replacement, reoperation, ICU and hospital stay, and death.

Review
Enterocystoplasty is the most commonly used treatment for bladder reconstruction. However, it has some major complications. In this study, we systematically reviewed the alternative techniques for enterocystoplasty using different scaffolds. A comprehensive search was conducted in PubMed, Embase, and Cochrane Library, and a total of 10 studies were included in this study. Five different scaffolds were evaluated, including small intestinal submucosa (SIS), biodegradable scaffolds seeded with autologous bladder muscle and urothelial cells, dura mater, human cadaveric bladder acellular matrix graft, and bovine pericardium. The overall results revealed that bladder reconstruction using regenerative medicine is an excellent alternative method to enterocystoplasty regarding the improvement of bladder capacity, bladder compliance, and maximum detrusor pressure; however, more large-scale studies are required.

BACKGROUND AND AIMS
Systemic inflammatory diseases could act as an unfavorable condition in which epicardial adipose tissue (EAT) becomes harmful to cardiovascular health. The objectives were: (a) to quantitatively compare the presence of EAT between patients with systemic inflammatory diseases and controls; (b) to analyze the association between EAT and subclinical atheromatosis in individuals with systemic inflammatory diseases.
METHODS
Studies that have quantified EAT in a population with systemic inflammatory diseases compared to a control group, or that describe the association between EAT and the presence of subclinical atheromatosis in patients with systemic inflammatory diseases were included. A quantitative analysis was performed for the first objective. This systematic review was performed according to PRISMA guidelines.
RESULTS
Twenty-one studies including 1448 patients with systemic inflammatory diseases, were considered eligible for this study. Patients with systemic inflammatory disease have a higher volume (MD: 10.4cm [1.8-19.1]; p<0.01), higher thickness (MD: 1.0mm [0.8-1.2]; p<0.01), and a statistically non-significant higher area (MD: 3.1cm [1.0-5.2]; p=0.46) of EAT compared to the control group. Most studies reported a significant association between EAT and subclinical atheromatosis in patients with different systemic inflammatory diseases.
CONCLUSION
This study demonstrated that EAT is increased in patients with systemic inflammatory diseases compared with healthy controls, and that EAT measurement is closely correlated with subclinical atherosclerosis in these patients. The causality of this association should be tested in prospective studies.
