The global impact of anticoagulant rodenticides (ARs) on non-target species is well-recognized. Birds of prey, as apex predators, are highly vulnerable to AR exposure and are widely used as biomonitors for priority pollutants in Europe. This study investigates differential SGAR exposure in raptors from insular versus continental regions, hypothesizing greater exposure in insular areas due to ecological factors like reduced prey diversity, intensive rodenticide use, and resistant rodent populations.

Specifically, in the Canary Islands, a high and concerning incidence of these compounds has been reported. However, in this scenario, reptiles remain one of the least studied taxa, despite their potential suitability as indicators of the food chain and environmental pollution has been noted on several occasions.

Article Synopsis
- * A study analyzed liver samples from 360 euthanized kingsnakes to detect 10 different ARs, finding that 90% tested positive, primarily for brodifacoum, and showed a correlation between the snakes' size and geographic location with AR concentration.
- * The study suggests that California kingsnakes could serve as sentinel species for monitoring ARs in the ecosystem due to similarities in AR types and prevalence with local raptors, although more
This study assesses the impact of second-generation anticoagulant rodenticides (SGARs) on the common kestrel (Falco tinnunculus canariensis) in Tenerife, Canary Islands. The analysis of 390 liver samples over 19 years using HPLC-MS/MS showed that 93.1 % of kestrels were exposed to SGARs in this island.

Objectives: The aims of this study were to assess the safety of vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in frail nursing home residents and to evaluate its effectiveness 6 months after full vaccination.
Design: This was an ambispective observational study.
Article Synopsis
- Animal poisoning poses a significant threat to wildlife, particularly in the Canary Islands, where the risk is higher than in other parts of Europe.
- A study from 2014 to 2021 analyzed 961 animals and 84 baits, revealing that 251 animals and 61 baits were poisoned, with carbofuran being the most common poison used.
- The introduction of canine patrols has improved the detection of poisoned animals, with higher rates of poison positivity found in rural areas and regions with intensive agricultural and livestock activities.

Article Synopsis
- The study adapted a QuEChERS-based method for analyzing hundreds of contaminants in liver samples, crucial for food safety and biomonitoring.
- The validated method can detect 351 contaminants, with 80% having a limit of quantification (LOQ) under 2 ng/g, and revealed that 29 contaminants were found in 42 consumer liver samples, predominantly 4,4'-DDE and various persistent organic pollutants (POPs).
- In a pilot biomonitoring study of 151 wild bird livers in the Canary Islands, the method detected 52 contaminants, highlighting elevated levels of anticoagulant rodenticides and agricultural pesticides, particularly in terrestrial and nocturnal birds.
Introduction: generalized hypermetabolism is common in cancer patients and increases the risk of complications when combined with the systemic effects of surgery.
Objective: the aim of this study was to clinically assess the implementation of a Nutritional Assessment and Support Program for patients undergoing colorectal surgery with a diagnosed neoplasia.
Material And Methods: a quasi-experimental study was performed with analyses before and after the implementation of the Nutritional Assessment and Support Program.
