Right dorsal colitis in horses: A multicenter retrospective study of 35 cases.

Background: Right dorsal colitis (RDC) is a nonsteroidal anti-inflammatory drug (NSAID) induced, protein losing enteropathy in horses associated with a high case fatality rate.

Objectives: To describe signalment, NSAID usage, clinical presentations, clinical pathology, ultrasonographic findings, treatments, outcomes, and factors associated with survival in horses diagnosed with RDC.

Animals: Thirty-five horses from 7 Australian equine hospitals diagnosed with RDC.

Hendra Virus: An Update on Diagnosis, Vaccination, and Biosecurity Protocols for Horses.

Hendra virus (HeV) emerged as a zoonotic pathogen in the 1990s, causing low morbidity but high mortality in humans and horses. Pteropid bats are the natural reservoir of HeV and other important zoonotic viruses such as Nipah and Ebola viruses. Equivac HeV, manufactured by Zoetis (Parkville, Victoria, Australia), is the only commercially available vaccine for horses.

Pharmacokinetic and pharmacodynamic effects of 2 registered omeprazole preparations and varying dose rates in horses.

Background: Omeprazole preparations vary in bioavailability in horses.

Hypothesis/objectives: To characterize the pharmacokinetics and pharmacodynamics of an existing enteric-coated oral omeprazole paste (REF) and a novel, in-feed, enteric-coated dry granule preparation (NOV).

Animals: Twelve Standardbred/Thoroughbred mares free from clinical disease.

Interobserver and intraobserver reliability for 2 grading systems for gastric ulcer syndrome in horses.

Background: Grading of equine gastric ulcer syndrome (EGUS) is undertaken in clinical and research settings, but the reliability of EGUS grading systems is poorly understood.

Hypothesis/objectives: Investigate interobserver and intraobserver reliability of an established ordinal grading system and a novel visual analog scale (VAS), and assess the influence of observer experience.

Animals: Sixty deidentified gastroscopy videos.

Intragastric pH of foals admitted to the intensive care unit.

Background: Intragastric pH profiles of neonatal foals admitted to the intensive care unit (ICU) remain poorly characterized.

Hypothesis/objectives: To determine intragastric pH profiles and clinical parameters associated with intragastric pH in foals admitted to the ICU.

Animals: Forty-two neonatal foals admitted to the ICU and requiring placement of an indwelling nasogastric tube for nutritional management were included.
