Author Abstract

Background: Squeezing the reservoir bag on the anaesthetic breathing system to inflate the lungs (colloquially known as bagging) is a technique commonly used during general anaesthesia in veterinary practice. Despite being straightforward to perform, the physiological implications are important to understand. Furthermore, catastrophic consequences can occur and staff must be vigilant and trained correctly when using this technique to manage ventilation during anaesthesia.

Aim of the article: This article provides an overview of the indications and contraindications of manual bagging, and reviews relevant literature from human medicine.

Coloration in Equine: Overview of Candidate Genes Associated with Coat Color Phenotypes.
In this review, we concisely categorize coat coloration in horses and donkeys, focusing on the biosynthesis and types of melanin involved in pigmentation. Moreover, the review explores how coat color relates to selective breeding and specific equine diseases, offering valuable insights for developing breeding strategies that enhance both the esthetic and health aspects of equine species.

How to Address Common Misconceptions About Nutrition
Choosing the optimal food for one’s pet can evoke many emotions. Love, confusion, fear, guilt, and complacency are just some of the feelings evoked by pet food industry marketing. Navigating which concerns are valid or fabricated is challenging.

Clinical characterization of a novel episodic ataxia in young working Cocker Spaniels.
The mean age at clinical onset was 4 months. Signs were acute and included episodic body swaying, titubation, cerebellar ataxia, wide-base stance, and hypermetria, all while mentation remained unaltered. Duration of episodes ranged from 30 minutes up to 24 hours, and their frequency varied from weekly to once every 5 months.

Prevalence of discospondylitis and association with congenital vertebral body malformations in English and French bulldogs.
The prevalence of discospondylitis was 3.4 (1.6-6.7) times higher in French bulldogs and 4.3 (1.7-9.8) times higher in English bulldogs, compared with the overall hospital cohort. One or more vertebral malformations were present in 12 French bulldogs (92.3%), 6 English bulldogs (75.0%), and 1 "other" breed dog (1.1%). Discospondylitis was diagnosed adjacent to congenital vertebral body malformations in 12 (80%) intervertebral discs in French bulldogs and 5 (50%) intervertebral discs in English bulldogs.

Association between highly pathogenic avian influenza outbreaks and weather conditions in Japan.
We found that higher average air temperatures two to three weeks prior, lower average wind speeds four weeks prior, and longer sunlight hours two and four weeks prior to outbreaks were significantly associated with increased risk of HPAI outbreaks in Japan. These results suggest that weather may influence environmental survival and transmission of the virus, as well as patterns of wild bird movement that could seed new outbreaks.
