A systematic review of cost-effectiveness of percutaneous coronary intervention vs. surgery for the treatment of multivessel coronary artery disease in the drug-eluting stent era.

Aims: The suitability of percutaneous coronary intervention (PCI), compared with coronary artery bypass grafting (CABG), for patients with complex multivessel coronary artery disease (MVCAD) remains a contentious topic. While the body of evidence regarding the clinical effectiveness of these revascularization strategies is growing, there is limited evidence concerning their long-term cost-effectiveness. We aim to critically appraise the body of literature investigating the cost-effectiveness of CABG compared with PCI using stents, and to assess the quality of the economic evidence available.

Prolonged effectiveness of coronary artery bypass surgery versus drug-eluting stents in diabetics with multi-vessel disease: an updated systematic review and meta-analysis.

Background: Currently, the appropriateness of percutaneous coronary intervention (PCI) using drug-eluting stents (DES) versus coronary artery bypass grafting (CABG) for patients with diabetes (DM) and multi-vessel disease (MVD) is uncertain due to limited evidence from few randomised controlled trials (RCTs). We aimed to compare the clinical effectiveness of CABG versus PCI-DES in DM-MVD patients using an evidence-based approach.

Methods: A systematic review and meta-analyses were conducted to compare the risk of all-cause mortality, myocardial infarction (MI), repeat revascularisation, cerebrovascular events (CVE), and major adverse cardiac or cerebrovascular events (MACCE).

Sustained function of genetically modified porcine lungs in an ex vivo model of pulmonary xenotransplantation.

Background: Xenotransplantation could provide a solution to the donor shortage that is currently the major barrier to solid-organ transplantation. The ability to breed pigs with multiple genetic modifications provides a unique opportunity to explore the immunologic challenges of pulmonary xenotransplantation.

Methods: Explanted lungs from wild-type and 3 groups of genetically modified pigs were studied: (i) α1,3-galactosyltransferase gene knockout (GTKO); (ii) GTKO pigs expressing the human complementary regulatory proteins CD55 and CD59 (GTKO/CD55-59); and (iii) GTKO pigs expressing both CD55-59 and CD39 (GTKO/CD55-59/CD39).

Safety and efficacy of extended-release bupivacaine local anaesthetic in open hernia repair: a randomized controlled trial.

Background: Pain relief remains a major problem in hernia surgery. SABER-Bupivacaine is an investigational extended-release formulation of bupivacaine in a resorbable matrix, which may provide up to 72 h of local pain relief.

Methods: A double-blinded, randomized controlled trial was undertaken to evaluate the safety and efficacy of SABER-Bupivacaine.
