Serum Lipid, Amino Acid and Acylcarnitine Profiles of Obese Cats Supplemented with Dietary Choline and Fed to Maintenance Energy Requirements.

Obesity is a health concern for domestic cats. Obesity and severe energy restriction predispose cats to feline hepatic lipidosis. As choline is linked to lipid metabolism, we hypothesized that dietary choline supplementation would assist in reducing hepatic fat through increased lipoprotein transport and fatty acid oxidation. Twelve obese cats (body condition score [BCS] ≥ 8/9) were split into two groups. Cats were fed a control (n = 6; 4587 mg choline/kg dry matter [DM]) or a high choline diet (n = 6; 18,957 mg choline/kg DM) for 5 weeks, for adult maintenance. On days 0 and 35, fasted blood was collected, and the body composition was assessed. Serum lipoprotein and biochemistry profiles, plasma amino acids and plasma acylcarnitines were analyzed. The body weight, BCS and body composition were unaffected (p > 0.05). Choline increased the serum cholesterol, triacylglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, very low-density lipoprotein cholesterol and plasma methionine (p < 0.05) and decreased the serum blood urea nitrogen and alkaline phosphatase (p < 0.05). Choline also reduced the plasma acylcarnitine to free carnitine ratio (p = 0.006). Choline may assist in eliminating hepatic fat through increased fat mobilization and enhanced methionine recycling.

Body composition of medium to giant breed dogs with or without cranial cruciate ligament disease.

OBJECTIVE: To describe the body composition of dogs with or without cranial cruciate ligament (CCL) disease. STUDY DESIGN: Cross-sectional. ANIMALS: Adult dogs in which CCL disease was diagnosed (n = 30) and adult dogs without clinical signs of orthopedic disease (n = 30). METHODS: Body weight, body condition score, and muscle condition score (MCS) were recorded. Body composition of the whole body and pelvic limbs were assessed by dual-energy x-ray absorptiometry. Body condition score, whole body, and pelvic limb body composition measurements were compared by using general linear mixed-model analysis of variance. Muscle condition score between groups was assessed by using a Mann-Whitney U test, while paired data were analyzed by using a Wilcoxon signed-rank test. RESULTS: Body fat percentage (P < .0001) was higher in affected dogs (38.78% ± 1.40) than in control dogs (27.49% ± 1.24). Affected dogs had lower MCS (1.90 ± 0.13, P < .0001) compared with control dogs (2.77 ± 0.08). The affected pelvic limb of affected dogs contained less lean soft tissues (P < .0001) but more fat (P = .0451) compared with the contralateral pelvic limb. CONCLUSION: Dogs with CCL disease were overweight compared with the control group. CLINICAL SIGNIFICANCE: Dogs that are overweight may be predisposed to developing CCL disease. Body composition changes in the pelvic limbs should be considered when managing the care of these dogs.

Assessment of canine and feline body composition by veterinary health care teams in Ontario, Canada.

Nutritional assessment guidelines recommend that veterinary teams assess the body composition of pets at every visit. The objective of this study was to determine how veterinary teams in Ontario, Canada assess body composition in cats and dogs. An online survey was distributed to veterinary teams, with questions on how often body composition is assessed, what methods are used, and demographics. The results demonstrated that 66.7% of respondents reported always assessing body composition. Of those, body condition scoring (99.4%) and body weight (99.4%) were used most often, with morphometry (41.2%) and muscle condition scoring (33.9%) used less frequently. Veterinary technicians were less likely to assess body composition compared with veterinarians. These results indicate that veterinary teams do not assess body composition as indicated by nutritional assessment guidelines. Thus, education of veterinary teams is needed, as body composition should be assessed for every patient as part of a complete nutritional assessment.

Évaluation de la composition corporelle canine et féline par les équipes de soins vétérinaires en Ontario, au Canada. Les lignes directrices sur l'évaluation nutritionnelle recommandent que les équipes vétérinaires évaluent la composition corporelle des animaux de compagnie à chaque visite. L'objectif de cette étude consistait à déterminer comment les équipes vétérinaires de l'Ontario, au Canada, évaluent la composition corporelle des chats et des chiens. Un sondage en ligne a été distribué aux équipes vétérinaires et posait des questions sur la fréquence de l'évaluation de la composition corporelle, les méthodes utilisées et les données démographiques. Les résultats ont montré que 66,7 % des répondants signalaient qu'ils évaluaient toujours la composition corporelle. Parmi les paramètres utilisées, les notes d'état corporel (99,4 %) et le poids corporel (99,4 %) étaient les plus souvent utilisés et les notes de morphométrie (41,2 %) et d'état musculaire (33,9 %) étaient les moins fréquemment utilisées. Il était moins probable que les techniciens vétérinaires évaluent la composition corporelle comparativement aux médecins vétérinaires. Ces résultats indiquent que les équipes vétérinaires n'évaluent pas la composition corporelle conformément aux lignes directrices sur l'évaluation nutritionnelle. Par conséquent, une éducation des équipes vétérinaires est requise, car la composition corporelle devrait être évaluée pour chaque patient dans le cadre d'une évaluation nutritionnelle complète.(Traduit par Isabelle Vallières).

Investigating laparoscopic psychomotor skills in veterinarians and veterinary technicians.

OBJECTIVES: To determine the influence of age, year of graduation, and video game experience on baseline laparoscopic psychomotor skills. STUDY DESIGN: Cross-sectional. SAMPLE POPULATION: Licensed veterinarians (n = 38) and registered veterinary technicians (VTs) (n = 49). METHODS: A laparoscopic box trainer was set up at the 2016 Ontario Veterinary Medical Association (OVMA) and the 2016 Ontario Association of Veterinary Technicians (OAVT) conferences held in Toronto, Ontario, Canada. Participants volunteered to perform a single repetition of a peg transfer (PT) exercise. Participants were given a short demonstration of the PT task prior to testing. A Spearman's rank correlation (rs ) was used to identify associations between baseline psychomotor skills and self-reported surgical and non-surgical experiences collected via survey. Mann-Whitney U tests were used to compare PT scores in veterinarians and VTs. A P-value of < .05 was considered significant. RESULTS: The mean age of participants was 36 years (range 21-67) and the majority were female (83%). In veterinarians, PT scores were highest in the most recent graduates (P = .01, rs = 0.42), and PT scores increased with self-reported VG experience (P = .02, rs = 0.38). PT scores correlated inversely with age (P = .02, rs = -0.37). No associations were observed in VTs (P > .05). Veterinary technicians that frequently used chopsticks scored higher than those without chopstick experience (P = .04). CONCLUSIONS: Age and year of graduation correlated inversely, while self-reported VG experience correlated positively with laparoscopic psychomotor skills of veterinarians, when assessed on a simulator. The use of chopsticks may contribute to the acquisition of psychomotor skills in VTs.
