A review of a strategic roadmapping exercise to advance clinical translation of photoacoustic imaging: From current barriers to future adoption

Photoacoustic imaging (PAI), also referred to as optoacoustic imaging, has shown promise in early-stage clinical trials in a range of applications from inflammatory diseases to cancer. While the first PAI systems have recently received regulatory approvals, successful adoption of PAI technology into healthcare systems for clinical decision making must still overcome a range of barriers, from education and training to data acquisition and interpretation. The International Photoacoustic Standardisation Consortium (IPASC) undertook an community exercise in 2022 to identify and understand these barriers, then develop a roadmap of strategic plans to address them. Here, we outline the nature and scope of the barriers that were identified, along with short-, medium- and long-term community efforts required to overcome them, both within and beyond the IPASC group

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). Results: A total of 1,837 and 3,052DM-MVD patientswere pooled fromfour RCTs (FREEDOM, SYNTAX,VA CARDS, and CARDia) and five non-randomised studies. At mean follow-up of 3 years, CABG comparedwith PCI-DES was associated with a lower risk of all-cause mortality and MI in RCTs. By contrast, no significant differences were observed in the mean 3.5-year risk of all-cause mortality and MI in non-randomised trials. However, the risk of repeat revascularisations following PCI-DES compared with CABG was 2.3 (95% CI = 1.8-2.8) and 3.0 (2.3- 4.2)-folds higher in RCTs and non-randomised trials, respectively. Accordingly, the risk of MACCE at 3 years following CABG compared with PCI-DES was lower in both RCTs and non-randomised trials [0.65 (: 0.55-0.77); and 0.77 (0.60-0.98), respectively]. Conclusions: Based on our pooled results, we recommend CABG compared with PCI-DES for patients with DM-MVD. Although non-randomised trials suggest no additional survival-, MI-, and CVE- benefit from CABG over PCI-DES, these results should be interpreted with care
