To date, environmental conditions have been enough to act as an effective barrier to prevent non-indigenous species from arriving and establishing in Arctic Canada. However, rapidly changing climatic conditions are creating more suitable habitats for non-indigenous species to potentially establish and become invasive. Concurrently, shipping traffic in parts of Arctic Canada has increased by over 250% since 1990, providing an effective vector for transporting non-indigenous species to the region.

Aims: The estimated glucose disposal rate (eGDR) is a simple, non-invasive measure of insulin resistance. In this exploratory analysis of FINEARTS-HF, we evaluated whether lower eGDR, reflecting greater insulin resistance, is associated with adverse outcomes in heart failure (HF).
Methods And Results: The eGDR was calculated at baseline using waist circumference, glycated haemoglobin, and hypertension status.

Aims: Skeletal muscle energetic augmentation might be a mechanism via which intravenous iron improves symptoms in heart failure, but no direct measurement of intrinsic mitochondrial function has been performed to support this notion. This molecular substudy of the FERRIC-HF II trial tested the hypothesis that ferric derisomaltose (FDI) would improve electron transport chain activity, given its high dependence on iron-sulfur clusters which facilitate electron transfer during oxidative phosphorylation.
Methods And Results: Vastus lateralis skeletal muscle biopsies were taken before and 2 weeks after randomization.

Aims: The PARACHUTE-HF trial (NCT04023227) is evaluating the effect of sacubitril/valsartan compared with enalapril on a hierarchical composite of cardiovascular events (cardiovascular death, first heart failure hospitalization), and change in N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels in participants with heart failure and reduced ejection fraction (HFrEF) caused by chronic Chagas cardiomyopathy (CCC). We describe the baseline characteristics of participants in PARACHUTE-HF compared with prior HFrEF trials.
Methods And Results: PARACHUTE-HF, a multicentre, active-controlled, open-label trial, enrolled 922 participants with confirmed CCC, New York Heart Association (NYHA) functional class II-IV, and left ventricular ejection fraction (LVEF) ≤40%.

The harvest of animals from the wild is a pervasive selective force, especially in fisheries, where harvesting often targets individuals with specific traits. While most research has focused on large-scale commercial or recreational fisheries, little attention has been paid to artisanal fisheries, particularly those targeting ornamental species. Furthermore, environmental factors such as temperature and oxygen levels influence the behaviour of fishes, such as boldness and sociability, but their role in the harvesting process remains poorly understood.
