Background: Transaxillary transcatheter aortic valve implantation (TAx-TAVI) is the most used alternative access when severe iliofemoral disease renders transfemoral access infeasible. Compared to surgical transaxillary access, a true percutaneous approach using vascular closure devices (VCD) has advantages but can be challenging. Herein, we describe the impact of the "unilateral, suture-mediated, dry-closure technique" on vascular safety and efficacy in patients undergoing true percutaneous TAx-TAVI.

Article Synopsis
  • In patients with acute coronary syndromes and multivessel disease, immediate and staged complete revascularization showed similar outcomes at 2 years regarding combined health events like mortality and heart attacks.
  • A total of 1,525 patients participated, and follow-up data were collected from 97.6% of them.
  • The only notable difference was a lower rate of myocardial infarction in the immediate complete revascularization group compared to the staged group, suggesting it might be a slightly better option in preventing heart attacks.

Human economic activities severely threaten freshwater fish biodiversity in different river basins. Trade makes the impact more mysterious and complex and confounds local efforts to protect freshwater biodiversity. To investigate the relationship between trade and freshwater fishes, we developed a river-basin economic transaction model that is applied to mainland China, home to 9% of the world's freshwater fish species.

Article Synopsis
  • Human economic activities significantly impact the production and consumption of goods, which is essential for meeting the United Nations Sustainable Development Goals (SDGs), though the relationship between economic growth and these goals is not fully understood.
  • The research developed six Environmental Footprint Indices to measure the environmental effects of economic activities, revealing that these indices have both synergistic and trade-off effects on SDG targets, with synergistic effects being more prominent.
  • The study found that as income levels rise, the positive correlation between Environmental Footprint Indices and SDG targets strengthens, indicating that improving production efficiency and consumption habits can notably help achieve SDGs, especially in lower-income countries.

Article Synopsis
  • The study investigates long-term outcomes after ST-segment myocardial infarction (STEMI), focusing on how different adverse events affect patient prognosis over a 10-year period.
  • Patients were randomized to receive either an everolimus-eluting stent or a bare-metal stent, and various predictors of composite adverse events (like death or revascularization) were analyzed.
  • Results showed that about one-third of patients experienced adverse events, with factors like age and diabetes being significant predictors, but the type of first event (target vessel failure vs. non-target vessel failure) did not significantly impact subsequent outcomes.

Background: Transcatheter valvular interventions affect cardiac and hemodynamic physiology by changing ventricular (un-)loading and metabolic demand as reflected by cardiac mechanoenergetics. Real-time quantifications of these changes are scarce. Pressure-volume loop (PVL) monitoring appraises both load-dependent and load-independent compounds of cardiac physiology including myocardial work, ventricular unloading, and ventricular-vascular interactions.

Disasters resulting from climate change and extreme weather events adversely impact crop and livestock production. While the direct impacts of these events on productivity are generally well known, the indirect supply-chain repercussions (spillovers) are still unclear. Here, applying an integrated modelling framework that considers economic and physical factors, we estimate spillovers in terms of social impacts (for example, loss of job and income) and health impacts (for example, nutrient availability and diet quality) resulting from disruptions in food supply chains, which cascade across regions and sectors.
