Procedure: Medical records of dogs with orthopedic and neurological conditions from 3 academic referral hospitals were reviewed.

Is Digital Video Recorded Simulated Suture Skills Testing Associated With Lower Stress and Anxiety Than Traditional In-Person Assessment for Veterinary Students?

Anxiety can affect exam performance so exploring methods to improve mental health and academic performance is relevant. The objectives of this study were to investigate stress amongst veterinary students undergoing simulated suture skills examinations and determine if digital video recording can reduce stress compared to in-person examination. Thirty-nine students were prospectively enrolled and randomized to undergo two simulated suture examinations, a session proctored by an in-person examiner or one digitally recorded with no proctor present and then crossed over to the other group.

Animals: Twenty-one client-owned cats.

Management of penetrating thoracic wounds from a dog attack in a Nigerian dwarf goat: A case report.

Pet goat ownership has gradually increased in popularity and veterinarians are expected to provide gold-standard treatments for these animals. As in small-animal practice, decision-making regarding thoracic bite injuries is challenging because of the variability in clinical, radiographic, and surgical findings. Mortality rates from dog bite wounds in small animals range between 15.

Quantification of circulating tumour cells over time in dogs with appendicular osteosarcoma.

Enumeration of circulating tumour cells (CTC) has shown promise for prognostication and guidance of therapeutic decisions in human cancers. The objective of this study was to enumerate CTC over time in dogs with naturally occurring osteosarcoma (OSA), and to determine correlation with patient outcome. Twenty-six dogs with OSA and no evidence of metastatic disease at the time of amputation were enrolled.

Effect of up to 30-days of storage at different temperatures on detection of feline kidney injury molecule-1 in urine.

Background: In humans, kidney injury molecule-1 (KIM-1) is a biomarker of acute kidney injury that can be quantified in urine. Preliminary investigation in cats with experimentally induced acute kidney injury showed that KIM-1 urine concentration correlated with kidney injury histopathology scores. A lateral flow assay (LFA) has recently become available for patient-side feline KIM-1 measurement.

ACVIM consensus statement on diagnosis and management of acute canine thoracolumbar intervertebral disc extrusion.

Background: Thoracolumbar intervertebral disc extrusion (TL-IVDE) is the most common cause of acute paraparesis and paraplegia in dogs; however, guidelines on management of the condition are lacking.

Objectives: To summarize the current literature as it relates to diagnosis and management of acute TL-IVDE in dogs, and to formulate clinically relevant evidence-based recommendations.

Animals: None.

Primary repair of nonsteroidal anti-inflammatory drug-associated full thickness gastrointestinal ulcers in 11 dogs.

Objective: To report the outcomes of dogs that underwent primary repair of gastroduodenal perforations associated with the administration of nonsteroidal anti-inflammatory drugs (NSAID). A secondary objective was to identify clinicopathological findings that predisposed dogs to postoperative death.

Study Design: Retrospective study.

Excellent Agreement of In-Person Scoring versus Scoring of Digitally Recorded Simulated Suture Skills Examination.

This study's objective was to evaluate the agreement between in-person performance scores and digitally recorded assessment scores by the same examiner using a simulated suturing skill examination. With ethics approval, veterinary students underwent a simulated skills examination proctored by an in-person examiner and simultaneously digitally recorded using two wide-angle cameras mounted overtop and to the side of the surgical field. Performance scores were based on a nine-item rubric.

Complications and outcomes associated with laparoscopic-assisted splenectomy in dogs.

Objective: To report the perioperative characteristics and outcomes of dogs undergoing laparoscopic-assisted splenectomy (LAS).

Animals: 136 client-owned dogs.

Procedures: Multicentric retrospective study.

Proteomic Assessment of Extracellular Vesicles from Canine Tissue Explants as a Pipeline to Identify Molecular Targets in Osteosarcoma: PSMD14/Rpn11 as a Proof of Principle.

Osteosarcoma (OS) is a highly malignant bone tumour that has seen little improvement in treatment modalities in the past 30 years. Understanding what molecules contribute to OS biology could aid in the discovery of novel therapies. Extracellular vesicles (EVs) serve as a mode of cell-to-cell communication and have the potential to uncover novel protein signatures.

Flow Cytometric Detection of Circulating Osteosarcoma Cells in Dogs.

Osteosarcoma (OSA) is a malignant tumor of middle-aged dogs and adolescent humans. The clinical outcome of OSA has not improved over more than three decades, and dogs typically succumb to metastatic disease within 6 months despite tumor resection through limb amputation and adjuvant chemotherapy. Therefore, undetectable tumor cells with potential to form metastases are present at diagnosis.
