History, radiography, echocardiography, and other medical recordings were reviewed. Dogs with PH were diagnosed and classified according to the American College of Veterinary Internal Medicine consensus guidelines. The EI was measured at end diastole (EId) and end systole (EIs). The t, Mann-Whitney U, and Kruskal-Wallis tests were used to compare EI between PH groups. Receiver operating characteristic curve analysis was applied to assess the EI for predicting PH and right-sided congestive heart failure. Pearson correlation analysis was used to evaluate the correlation of EId and EIs with both tricuspid regurgitation velocity and right pulmonary artery distensibility index.Results: This study enrolled 37 healthy (control) and 84 dogs with PH. Both EId and EIs were significantly different between the control and PH groups (EId/EIs, 1.16/1.13 vs 1.31/1.66). An EIs value of 1.22 distinguished the 2 groups with a sensitivity of 0.7 and specificity of 1 (AUC, 0.78). Both EId and EIs were positively correlated with tricuspid regurgitation velocity but not with the right pulmonary artery distensibility index.Conclusions: The EI is useful for evaluating septal flattening in dogs with PH under various conditions. The EId showed inferior power to the EIs in assessing PH but aided screening for right-sided congestive heart failure and volume overload.Clinical relevance: The EI can help clinicians to more accurately assess PH probabilities, specifically regarding ventricles.","PeriodicalId":7754,"journal":{"name":"American journal of veterinary research","volume":" ","pages":"1-8"},"PeriodicalIF":1.3,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144109429","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}

Responses were summarized, and descriptive statistics were performed.Results: One hundred seventy-six of 594 (29.6%) veterinary students responded to the survey. One hundred forty-one out of 176 (80%) students reported slight or no knowledge surrounding AI/ML, and 139/176 (79%) of students were moderately to extremely interested in learning about AI/ML applications in veterinary medicine. Sixty-five out of 176 (37%) students reported learning about AI/ML concepts in their veterinary curriculum. Most students expect to use these tools in their practice (104/176 [59%]) and suspect that AI/ML will improve veterinary medicine (135/176 [77%]).Conclusions: Artificial intelligence and machine learning applications in veterinary medicine are increasingly available. Professional veterinary students are eager to learn about these technologies and recognize their relevance to their future careers.Clinical relevance: Many professional veterinary programs do not provide structured AI/ML literacy training.

The silicone skin model was inoculated with a 1,000-fold dilution of approximately 1.5 X 108 CFUs/mL of isolated Staphylococcus pseudintermedius or Escherichia coli. Bacterial quantification samples were taken preinoculation, 20 minutes postinoculation, and after incremental saline lavage to total a volume of 2.5, 5, and 10 mL/cm incisional length bacterial quantification.Results: For S pseudintermedius and E coli, a reduction of bacterial colonies below 105 CFUs/mL was noted in all lavage volumes, with an initial 3-log decrease from postinoculation to the 2.5 mL/cm lavage for both S pseudintermedius and E coli. Microbial growth demonstrated a 1-log reduction with increased lavage volumes from 2.5 mL/cm to 10 mL/cm for S pseudintermedius. For E coli, microbial growth demonstrated a 1-log reduction with the second lavage (total of 5 mL/cm) and a half-log reduction with the third lavage (total of 10 mL/cm).Conclusions: Surgeons should consider a minimum of 2.5 mL/cm lavage when aiming to decontaminate SC tissues in linear surgical wounds.

Following initial patient positioning in true lateral recumbency, fluoroscopic measurement of changes in positioning was performed for each plane at 2 separate time points: after draping (M1) and immediately prior to cup impaction (M2).Results: Patient positioning was significantly altered at time point M1 in the transverse plane, with a mean change of 2.8° (range, 0° to 12°); this change in position was most often toward the dorsum, occurring in 16 of 26 cases (62%). Significant shifting was found at time point M2 in the transverse plane, with a mean change of 2.6° (range, 0° to 10.3°); this change, however, did not significantly correlate with a particular direction. Positioning shifts found at M1 and M2 were not consistently in the same direction in either plane.

Horses also underwent an objective lameness examination and were included if they had a hindlimb impact lameness (Pmin ≥ 3 mm), which positively responded (≥ 50%) to the tarsometatarsal and centrodistal joints' anesthetic block. Horses randomly received an intra-articular injection of BoNT-A or an equivalent volume of saline solution. Horses were reevaluated at postinjection days (PIDs) 1, 7, 15, 30, 60, 90, 120, 150, and 180.

The study design was an experimental study on cadavers. Patellar ligaments were transected and sutured using a Bunnell and simple interrupted epitendinous pattern. They were then randomly reinforced with 1 of 3 techniques: a circumpatellar suture loop anchored distally to the tibial tuberosity (group 1), the same loop combined with a fascia lata strip (group 2), or a polyethylene synthetic implant sutured over the patella proximally and secured distally with an interference screw (group 3). Yield, peak, and failure load, stiffness, and mode of failure were evaluated.Results: Six hindlimbs were assigned to each group. Augmentation with the synthetic implant (group 3) showed significantly greater yield, peak, and failure load than group 1. There were no significant differences between group 2 and either group 1 or group 3.Conclusions: Patellar ligament repair augmented with a synthetic ultrahigh-molecular-weight polyethylene implant offered greater tensile strength than a Bunnell suture with an adjunction of a circumpatellar repair.Clinical relevance: The use of a synthetic ultrahigh-molecular-weight polyethylene implant may offer a viable surgical option for patellar ligament repair.

Four blinded veterinary dermatologists independently graded a 50-image reference set using the HDS. Inter-rater agreement was assessed using the quadratic-weighted Fleiss κ, Brennan-Prediger, and Gwet AC2 coefficients. A double-blind, randomized, controlled trial was performed using a convenience sample of alopecia X dogs recruited based on inclusion and exclusion criteria over 16 months. Photoconverter gels were applied on both alopecic sides of each patient once per week for 8 weeks. One randomly chosen side was exposed to excitatory light (active treatment) but not the other (sham). Skin biopsies were taken from the center of each treated side before and at the end of the study. The images of active and sham sides acquired before the study, at day 50, and at the end of the study were graded using the HDS.Results: Inter-rater agreement coefficients were greater or equal to 0.81. Seven dogs were enrolled, but 1 withdrew after day 50. Hair density score evolved over time in both sides, but the OR of improved HDS increased with time only for the 3 central HDS grades.
