Rattlesnake bite severity score (RBSS), platelet count, prothrombin time, activated thromboplastin time, D-dimers, antithrombin, and viscoelastic testing variables were assessed before and after antivenom administration. Paired comparisons of hemostatic variables between admission and approximately 24 hours, and correlation analysis with RBSS, were performed. Length of hospitalization (LOH) and outcome were recorded.Results: Seven acutely envenomated equids. Admit median (IQR) RBSS was 7 (4 to 7) out of 13. At admission, coagulopathies were present in all animals. Most common findings were thrombocytopenia, increased D-dimers, abnormal amplitude at 20 minutes (A20), and abnormal maximum clot firmness (MCF) on viscoelastic testing. On the day following admission, RBSS [3 (1 to 3)], A20 (admit, 15.8 ± 10; recheck, 26.4 ± 5), and MCF (admit, 18.7 ± 9.5; recheck, 28.8 ± 6) were improved. Significant correlations were found between RBSS and platelet count (ρ = -0.68; n = 12), activated thromboplastin time (ρ = 0.64; n = 14), A20 (r = -0.70; n = 14), and MCF (ρ = -0.56; n = 14).

The experimental procedures were carried out from August 1, 2024, through February 1, 2025. Specimens were randomly assigned to either the guided or nonguided group. Mandibular fractures were simulated and stabilized with plate fixation and intraosseous wiring. Tooth-supported, 3-D-printed, patient-specific reduction guides were individually designed using CT imaging and computer-aided design software based on the dental anatomy of each specimen. Surgical time was recorded to assess procedural efficiency. Postoperative CT scans were used to evaluate fracture alignment (rostrocaudal, dorsoventral, and mediolateral angulations), fracture gap volume, and the presence of breaches involving the mandibular canal or tooth roots.Results: Use of the TPSRG resulted in improved alignment in rostrocaudal and dorsoventral angulations and a smaller fracture gap compared to the nonguided group. Mediolateral alignment showed no difference. Surgical time was shorter in the TPSRG group. Structural breach rates did not differ between groups.Conclusions: The TPSRG enhanced alignment accuracy and surgical efficiency in mandibular fracture repair using canine cadaver models, though it did not significantly reduce the incidence of structural breaches.Clinical relevance: TPSRGs show promise as adjunctive tools to enhance precision and efficiency in the surgical management of simple mandibular fractures in dogs.","PeriodicalId":7754,"journal":{"name":"American journal of veterinary research","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144666894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All study dogs had CBCs and serum biochemistry profiles, and blood samples were collected for platelet isolation. Gene expression profiling of isolated platelets was performed using a commercial multiplex assay based on direct hybridization and detection of single RNA molecules bar coded with fluorescent probes. Quality control, normalization, and data visualization were performed using standardized workflows. Raw counts were exported, and differential expression between groups was assessed.Results: 6 client-owned dogs with sepsis and 6 healthy dogs were enrolled from March through August 2023. Platelet isolation and transcript profiling were successful for all dogs. The septic dog group included 3 males and 3 females with peritonitis (n = 3), pyometra (n = 2), and pyothorax. Principal component analysis did not fully segregate septic from healthy dogs, but disease status accounted for 59% of the variance. Upregulated genes contributing substantially to principal component analysis variance included those for S100 calcium-binding proteins (S100s) and cytokines. Significantly upregulated genes based on log2 fold change included S100A8, S100A12, cathelicidin, lactoferrin, and innate immune response signaling proteins.Conclusions: Sample processing and data analysis workflows are scalable to larger, confirmatory studies to explore potential sepsis biomarkers.Clinical relevance: Platelet gene expression profiles might offer insights into sepsis pathophysiology and potential diagnostic and prognostic biomarkers.

Exclusions included AV pathology, congestive heart failure, systolic dysfunction, sustained arrhythmias, congenital heart diseases, hypovolemia, systemic hypertension, and pericardial and pleural space diseases. The AVd was measured in centimeters in triplicate using digital calipers. A linear regression examined the relationship between weight and AVd, generating a predictive formula. Next, 20 dogs had their AVd measured and predicted, and stroke volumes were calculated using each method. These were compared using the paired Student t test, intraclass correlation coefficients, coefficients of variation, and Bland-Altman plots.Results: Data from 176 unique dogs included 64 (34.7%) normal hearts and 109 (61.9%) with preclinical myxomatous mitral and/or tricuspid valve disease. The median (range) age was 8 (1 to 16) years; weight was 9.6 (1.7 to 73) kg. The median (range) AVd was 1.20 (0.60 to 2.45) cm. The formula derived was AVd = 0.545 X (weight)0.347 (r2 = 0.875). Despite moderate agreement and low variation between the predicted and measured AVd, differences occurred due to mild systematic underestimation (-0.1 ± 0.13 cm), with consequent underestimation of stroke volumes.Conclusions: The formula allowed calculation of AVd, although underestimation resulted in differences between measured and predicted stroke volumes.Clinical relevance: Using a formula can reduce acquisition and measurement error; however, it must be validated with a larger sample.","PeriodicalId":7754,"journal":{"name":"American journal of veterinary research","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144666891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Meta-analysis of single proportions was performed to estimate within-herd and pooled serologic and molecular prevalence with 95% binomial CIs.Results: A total of 908 serum samples paired with 757 whole blood samples were received from 59 herds in 34 Missouri counties.

A CT image of the tibia from a 2-year-old 12-kg castrated male Jindo dog was used to create 21 polycarbonate 3-D-printed bone models, and 7 were assigned to each group. The TBW group was stabilized with two 1.2-mm K-wires and figure-of-8 TBW (20 gauge), the FTLPS group was stabilized with a 3.5-mm FTLPS, and the FTHCS group was stabilized with a 3.5-mm FTHCS. Tensile load was applied at 0.2 mm/s using a universal testing machine, and failure load was recorded.Results: The mean failure load for the TBW, FTLPS, and FTHCS groups was 238.0 ± 38.1 N, 187.3 ± 50.8 N, and 215.5 ± 35.2 N, respectively. There were no statistically significant differences among groups. All screw fixed models failed by fracture of the malleolar fragment.Conclusions: The FTHCS fixation showed comparable failure loads to conventional fixation methods in this model. While promising, its use may be appropriate only when fragment size and bone quality are sufficient.Clinical relevance: While failure loads and mechanisms were similar in this model, further investigation into the relative size of the screw to the fragment is necessary to guide the clinical application of this device.","PeriodicalId":7754,"journal":{"name":"American journal of veterinary research","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144658157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
