Biomarkers of Intestinal Injury in Colic

Animals, 13(2), 227.

By: E. Ludwig n, K. Hobbs n , C. McKinney-Aguirre n  & L. Gonzalez n 

Contributors: E. Ludwig n, K. Hobbs n , C. McKinney-Aguirre n  & L. Gonzalez n 

author keywords: colic; intestine; ischemia; biomarker; acute phase protein; cytokine
topics (OpenAlex): Veterinary Equine Medical Research; Animal health and immunology; Reproductive Physiology in Livestock
TL;DR: Ultimately, based on this review, L-lactate continues to be the most reliable marker for intestinal ischemia during colic, and further exploration of the biomarkers discussed in this review may provide the key to accelerated identification, intervention, and better outcomes for horses suffering from severe colic.

Intravenous loss of over-the-wire catheter guidewires in 13 horses

Hobbs, K. J., Young, K. A. S., Nannarone, S., Luethy, D., Hopster-Iversen, C., McKenzie, H. C., & Ludwig, E. K. (2023, December 14). Journal of Veterinary Internal Medicine, Vol. 12.

By: K. Hobbs n , K. Young n, S. Nannarone *, D. Luethy *, C. Hopster-Iversen *, H. McKenzie *, E. Ludwig n

author keywords: catheter; equine; guidewire; intravenous
MeSH headings : Animals; Horses; Retrospective Studies; Catheters; Physical Therapy Modalities / veterinary
topics (OpenAlex): Central Venous Catheters and Hemodialysis; Hemodynamic Monitoring and Therapy; Cardiac Arrhythmias and Treatments; Antibiotics Pharmacokinetics and Efficacy
TL;DR: Intravenous guidewire loss seems to have a good long‐term prognosis even in horses in which removal of the guidewire was not possible, and in horses where guidewire removal is not feasible, guidewires that remain in situ may have limited to no adverse effects. (via Semantic Scholar)
