Horses underwent GPC (0.5 g glycemic carbohydrates/kg body weight) and OST (0.15 mL corn syrup/kg body weight) 7 days apart. Feed was withheld before testing and blood samples were collected at T0, T60, T120, and T180 minutes for GPC and at T0, T60, and T90 minutes for OST. Blood glucose concentration was measured using a point-of-care glucometer and insulin by radioimmunoassay. Comparisons were made using nonparametric tests, linear regression, and Bland-Altman agreement analysis.Results: Eighteen horses consumed >85% of the GPC pellets within 10 minutes and had acceptable OST results. Maximum glucose (P = .02) and insulin (P = .007) concentrations were significantly higher for GPC compared with OST. Time to maximum insulin concentration (Tmax[ins]) varied within and between tests and neither Tmax[ins] (P = .28) nor maximum insulin concentration (P = .46) was correlated with the time horses took to consume pellets.Conclusions: The GPC is well tolerated and may offer another diagnostic testing modality for ID. Blood glucose and insulin concentrations increase during GPC and reach higher concentrations than observed with low-dose OST. The Tmax[ins] varied for GPC and OST, emphasizing the importance of identifying the optimal time range for the collection of samples to capture diagnostically relevant changes in insulin concentration.","PeriodicalId":17462,"journal":{"name":"Journal of Veterinary Internal Medicine","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142502938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The horses receiving a pelleted diet, high in sugar and starch (>30%), were examined at T0 and after 12 weeks (T12) of changing to a cooked, muesli-type low-starch (11%) diet. Each time, the horses underwent a standardized exercise test (SET) and a ridden pain score (Ridden Horse Pain Ethogram [RHpE]) was calculated by 2 blinded observers. The next day, horses underwent gastroscopy and gastric lesions were scored blindly. Results were analyzed using Wilcoxon and Spearman tests.Results: After 12 weeks of a low starch diet, the Equine Gastric Disease (EGD; 4 [3-5] at T0 vs 1 [0-1] at T12, P < .01) and RHpE scores (6 [3-13] at T0 vs 3 [0-6] at T12, P < .01) improved significantly. Squamous, glandular, and EGD scores were positively correlated with RHpE scores (respectively, r = .747, P < .01; r = .743, P < .01 and r = .867, P < .01).Conclusion and clinical importance: Gastric disease and pain scores correlated positively in ridden horses. A low starch diet significantly decreases the severity of gastric disease and associated pain score during riding in horses.

However, comprehensive data on the alteration of metabolites associated with this condition remains sparse.Hypothesis: Delineate serum metabolite profiles and metabolic pathways preceding, coinciding with, and after the onset of MF.Animals: Twenty-six cows, including 20 healthy cows and 6 cows initially affected by MF. Because of culling, the number of MF-affected cows decreased to 4 at MF week, +4 weeks, and +8 weeks postpartum.Methods: A nested case-control longitudinal study was conducted, with blood samples collected at -8 and -4 weeks prepartum, MF week, and +4 and +8 weeks postpartum. Serum analysis utilized direct injection/liquid chromatography/tandem mass spectrometry (DI/LC/MS/MS) techniques.Results: Key findings included the identification of diverse metabolites such as hexose, amino acids, phosphatidylcholines, lysophosphatidylcholines, and sphingomyelin, which varied between studied groups (P < .05). The most marked metabolic alterations were observed 4 weeks prepartum. In total, 42, 56, 38, 29, and 24 metabolites distinguished the MF group at the respective time points (P < .05). Additionally, 33 metabolic pathways, including amino acid, antioxidant metabolism, fatty acid degradation, and carbohydrate processing, were impacted (P < .05).Conclusions and clinical importance: Metabolic disruptions in dairy cows begin several weeks before the clinical manifestation of MF and persist up to 8 weeks postpartum. These findings emphasize the complexity of MF, extending beyond only hypocalcemia and indicate the necessity for preemptive monitoring in dairy herd management.","PeriodicalId":17462,"journal":{"name":"Journal of Veterinary Internal Medicine","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142522247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On histological examination, the physeal cartilages were characterized by multifocal mild to moderate loss of the normal columnar arrangement of chondrocytes. Osteopenia also was observed. Genetic analysis identified a missense variant in TGDS and a splice-site variant in LAMA4, both of which were homozygous in the 2 cases.

Dogs were included if suitable nasopharynx images were available for review. Univariable and multivariable logistic regression analyses were performed to determine the factors associated with these masses.Results: One-hundred ninety-eight dogs met the inclusion criteria of which 47.9% (95/198) had a dorsal nasopharyngeal mass.

Univariable analysis identified associations between the presence of a nasopharyngeal mass and several factors: brachycephalic conformation (P < .001), sleep disturbances (P = .04), presence of laryngeal collapse (P = .01), and aberrant caudal turbinates (P = .04). However, according to the multivariable analysis, only the association between the presence of a mass and brachycephalic conformation was significant (odds ratio = 2.3 [1.1; 5.0], P = .03).Conclusion and clinical importance: Dorsomedian nasopharyngeal masses were common in the studied dog population.

Little is known about RAAS peptide activation in horses.Hypothesis/objectives: To evaluate equilibrium analysis as a practical method for RAAS quantification in horses and describe the RAAS response to a single dose of furosemide. We hypothesize that furosemide would cause transient increase in RAAS peptides in horses.Animals: 14 healthy adult thoroughbreds from a university teaching herd.Methods: Horses received either furosemide (1 mg/kg IV) or saline IV in a crossover study design. Protease-inhibited samples were compared with equilibrium analysis samples with Deming regression analysis. Renin-angiotensin-aldosterone system hormones were evaluated at 0, 0.25, 0.5, 4, and 24 hours postadministration, via equilibrium analysis. Values were compared with a mixed effects model.Results: Correlation between protease inhibition and equilibrium analysis was high for angiotensin I peptide (AngI) and angiotensin II peptide (AngII) (r = .92 and .95, respectively). Baseline RAAS peptide concentrations were below the limit of detection except AngII (median, 7.5 [range, 3.5-14.0] pmol/L).

Whether this drug interaction occurs in cats is unknown.Hypothesis: We hypothesized that administration of clopidogrel with omeprazole would decrease plasma CAM concentrations and decrease clopidogrel antiplatelet effects in healthy cats.Animals: Ten domestic cats.Methods: In this 2-sequence, 2-period, 2-treatment randomized crossover study, healthy cats were randomly assigned to receive clopidogrel only (18.75 mg PO q24h) or clopidogrel with omeprazole (1 mg/kg PO q12h) for 10 days, followed by a 2-week washout period, and then the opposite treatment for another 10 days. Blood was collected by jugular venipuncture on days 0, 5, and 10. Plasma CAM concentrations were measured using high-performance liquid chromatography-tandem mass spectrometry. Platelet function was evaluated using Plateletworks, Multiplate Analyzer, and Platelet Function Analyzer-100 (PFA-100).Results: Multiplate Analyzer and PFA-100 detected no difference in platelet function between days or treatment groups. Plateletworks detected a significant difference (P < .001) in platelet function from day 0 to 5 and day 0 to 10 in both treatment groups but no difference between treatment groups.
