Landscape‐Wide Metabarcoding Shows Interactions Among the Gut Microbiome and Pollen Diversity in the Invasive Bumblebee, Bombus terrestris

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
The study examines how environmental factors and dietary diversity influence the gut microbiome of the invasive European buff‐tailed bumblebee (Bombus terrestris) in Tasmania. We found that gut bacterial composition and diversity were significantly affected by annual precipitation, pasture percentage, temperature and interactions between pollen ...

The effect of down‐titration and discontinuation of heart failure pharmacotherapy in older people: A systematic review and meta‐analysis

open access: yesBritish Journal of Clinical Pharmacology, Volume 91, Issue 1, Page 23-37, January 2025.
The aim of this study was to investigate whether interventions to discontinue or down‐titrate heart failure (HF) pharmacotherapy are feasible and associated with risks in older people. A systematic review and meta‐analysis were conducted according to PRISMA 2020 guidelines. Electronic databases were searched from inception to 8 March 2023.
