    Kurzfassung: The positive impact of minimally invasive extracorporeal circuits (MiECC) on patient outcome is expected to be most evident in patients with limited physiologic reserves. Nevertheless, most studies have limited their use to low-risk patients undergoing myocardial revascularization. As such, there is little evidence to their benefit outside this patient population. We, therefore, set out to explore their potential benefit in octogenarians undergoing aortic valve replacement (AVR) with or without concomitant myocardial revascularization. Methods: Based on the type of the utilized ECC, we performed a retrospective propensity score-matched comparison among all octogenarians (n = 218) who received a primary AVR with or without concomitant coronary artery bypass grafting in our institution between 2003 and 2010. Results: A MiECC was utilized in 32% of the patients. The propensity score matching yielded 52 matched pairs. The 30-day postoperative mortality (2% vs. 10%; p=0.2), the incidence of low cardiac output (0% vs. 6%; p=0.2) and the Intensive Care Unit (ICU) stay (2.5 ± 2.6 vs. 3.8 ± 4.7 days; p=0.06) were all in favour of the MiECC group, but failed to reach statistical significance while the 90-day postoperative mortality did (2% vs. 16%; p=0.02). Conclusion: MiECCs have a positive influence on the outcome of octogenarians undergoing AVR with or without concomitant coronary artery bypass grafting. Their use should, therefore, be extended beyond isolated coronary artery bypass graft (CABG) surgery.

    Kurzfassung: Study visits are an underresearched phenomenon, particularly in the field of climate change adaptation. Drawing on interviews with key local stakeholders, this article investigates study visits organized by European municipal climate networks. The results of this exploratory research show that study visits about adaptation policies can (1) particularly stimulate conceptual learning, (2) increase the credibility of policies within municipal administrations, (3) be used as strategic instruments by mentor cities, (4) be more successful if the peer-cities are not too different (in terms of size, institutional context), and (5) under certain conditions, lead to policy adoption in a learning city. Future research needs to critically discuss the mass suitability of learning from frontrunner cities. Furthermore, a call is raised for more research and practical action on how to initiate and improve learning exchanges beyond the strict division between mentors and learners. Instead, the focus needs to be on mutual learning exchanges.
