Agriculture is a major source of nitrogen (N) and phosphorus (P) in freshwater ecosystems, and different management strategies exist to reduce farmland nutrient losses and thus mitigate freshwater eutrophication. The importance of agricultural sources of N and P as drivers of water quality is known to vary spatially, but quantification of the relative importance of the nutrient sources shaping this variability remains challenging, especially with reference to inputs from waste water treatment works. Addressing this knowledge gap is key for targeting management strategies to where they are likely to have the greatest effect.

Article Synopsis
- Big biodiversity data sets are valuable for tracking changes in species populations and distributions but often have gaps that can obscure accurate assessments.
- Characterizing these gaps as a missing data problem offers a framework to understand how they affect research on species trends and occurrences.
- Various methods like subsampling, weighting, and imputation can help address these data gaps, yet they may introduce uncertainties in parameter estimates, with weighting being underutilized in ecological studies.

Article Synopsis
- * They identified 30 clinical and diagnostic scenarios relevant to cardiovascular care and conducted a rapid scoping review to find existing systematic referral guidelines for these scenarios.
- * As a result, they developed 125 recommendation statements based on insights from 48 guidelines to address various conditions such as acute and chronic chest pain, cardiovascular screening, pericardial syndromes, and other vascular diseases.
Background: The objective of this study was to evaluate the influence of two crucial variables, the American Society of Anesthesiologists (ASA) score and operative time, on the occurrence of surgical site infections (SSIs) in the context of major abdominal surgical procedures.
Methodology: A cross-sectional research study involved patients undergoing various gastrointestinal surgical procedures. Surgical details, procedure duration, and ASA score were meticulously documented.
