Data inaccessibility at sub-county scale limits implementation of manuresheds.

J Environ Qual 2021 Jul 22. Epub 2021 Jul 22.

Department of Agronomy, University of Wisconsin - Madison, 1575 Linden Drive, Madison, WI, 53705.

The manureshed concept aims to rebalance surplus manure nutrients produced at animal feeding operations (sources) and the demands from nutrient-deficient croplands (sinks) to reduce negative environmental impacts and utilize nutrients more efficiently. Due to water quality implications, studies focused on this re-balancing have typically created domain boundaries that match a particular watershed. However, a majority of agricultural datasets that are used to inform these analyses - specifically, livestock populations - are only available at the county scale, which generally do not match watershed boundaries.

Working towards full eradication of lipid-driven cardiovascular risk?

Neth Heart J 2021 Jul 19. Epub 2021 Jul 19.

Department of Vascular Medicine, Amsterdam UMC, University of Amsterdam, Amsterdam, The Netherlands.

Lipid-driven cardiovascular disease (CVD) risk is caused by atherogenic apolipoprotein B (apoB) particles containing low-density lipoprotein cholesterol (LDL-C), triglycerides and lipoprotein(a) [Lp(a)] and resembles a large and modifiable proportion of the total CVD risk. While a surplus of novel lipid-lowering therapies has been developed in recent years, management of lipid-driven CVD risk in the Netherlands remains suboptimal. To lower LDL‑C levels, statins, ezetimibe and proprotein convertase subtilisin/kexin type 9 inhibiting antibodies are the current standard of therapy. Read More
