Abstract
OBJECTIVE
To evaluate the knowledge, attitudes, and practices toward antibiotic use among board-certified veterinary dentists.
SAMPLE
104 veterinarians board certified by the American Veterinary Dental College.
METHODS
A 30-question survey was generated from an online platform and sent via email listserv to board-certified veterinary dentists. Responses were examined to identify patterns or correlations among the variables of interest.
RESULTS
There were 104 board-certified veterinary dentists who responded. The majority reported using prophylactic intraoperative antibiotics sparingly for dental procedures and predominately for patients with historic endocarditis or on immunosuppressive doses of steroids. For healthy patients, they reported that antibiotics are often prescribed during jaw fracture repair, maxillectomy/mandibulectomy, and treatment of stage 4 periodontal disease or periapical lucencies. Knowledge of antibiotic resistance and evidence-based antibiotic use were not significantly different between different practice sectors (academia vs private practice) or dependent on the duration of board certification. Dentists who did not believe antibiotics used postoperatively reduce local postoperative infection rates were less likely to prescribe injectable intraoperative antibiotics for the prevention of postoperative infection. No other variables were associated with the likelihood of prescribing intraoperative antibiotics. More than 95% of veterinary dentists surveyed agreed that specific antibiotic use guidelines for veterinary dentistry would help reduce inappropriate use of antibiotics.
CLINICAL RELEVANCE
There are differences among veterinary dentists regarding which procedures and patient-specific comorbidities they believe necessitate the use of prophylactic antibiotics. The development of a consensus statement and prospective studies of current antibiotic use are important next steps to improving antibiotic stewardship in veterinary dentistry.
Abstract
OBJECTIVE
To compare the effect of volume and solution on transit time and fluorescence intensity (FI) using near-infrared fluorescence imaging (NIRF) in a simulated tumor model in cats. Secondarily, to describe SLN mapping with indocyanine green (ICG) NIRF and report any adverse effects of intradermally injected ICG in cats.
ANIMALS
7 healthy purpose-bred domestic shorthaired male cats.
METHODS
Cats were randomly divided into 2 groups (ICG or ICG + methylene blue [MB]). Transit time and FI were determined for 1 or 2 mL solutions injected intradermally in 4 quadrants around a simulated tumor. Following massage, fluorescence intensity was quantified by calculating the corrected total ROI fluorescence using ImageJ software. Cats were monitored for adverse effects up to 4 weeks post-injection.
RESULTS
A larger solution volume had decreased transit times to the SLN (P = .001). There was no significant difference in transit times between ICG and ICG-MB. ICG demonstrated a greater FI (P = .001) in the SLN compared to ICG-MB. Methylene blue did not percutaneously fluoresce under NIRF. The volume of the solution did not significantly affect FI. No adverse reactions were reported.
CLINICAL RELEVANCE
Increased volume of ICG may aid in rapid percutaneous lymphatic tracking from tumor to SLN. Indocyanine green alone may be preferred over ICG-MB for greater visualization of the SLN. Intradermal injections of ICG and ICG-MB were well-tolerated in healthy cats with no significant complications. Clinical evaluation of this technique in an impaired lymphatic system, as seen in cancer patients, should be assessed in future research.
Abstract
OBJECTIVE
To establish and compare the precision of serum total protein (STP) measured by an optical refractometer to the precision of IgG concentrations measured using radial immunodiffusion (RID), the reference test for quantifying IgG in neonatal calves.
SAMPLE
6 sera with previously measured IgG concentration using RID from neonatal beef calves were selected from 3 stratum: low-serum IgG stratum between >5.0 and <15.0g/L(n = 4); moderate-serum IgG stratum between 35.0–45.0g/L(n = 1); high-serum IgG stratum between 60.0–70.0g/L(n = 1).
METHODS
STP was measured 13 times with an optical refractometer. IgG concentrations were measured 28 times with a commercial bovine IgG RID for each sera. The homogeneity of variance within the tests was evaluated with the Levene test (α = 0.10). Unrestricted random sampling bootstrapping (5,000 repetitions) was used to calculate the coefficient of variation (CV) for each serum and test. The homogeneity of variance between simulated test CVs by serum was evaluated (α = 0.10). Differences between simulated test CV by serum were assessed with the Kruskal-Wallis test (α = 0.05).
RESULTS
No difference was observed in the variance for STP between sera (P = .39). The average CV for STP was 4.2%, 10.1% for the low IgG stratum, and 15.5% for the moderate/high IgG stratum. Variance differed in serum IgG concentration (P < .0001). Serum with higher IgG concentrations had more variance. Simulated CV for STP and IgG had homogeneity of variance for only 1 sera (P = .31). STP had a smaller CV compared to IgG for every serum (P < .0001).
CLINICAL RELEVANCE
Estimating IgG concentration directly by RID or indirectly by STP lacks the precision that might affect diagnostic interpretation regarding a calf’s absorption of maternal antibodies.
Abstract
OBJECTIVE
To investigate the use of a locking 3.5/4.0-mm jumbo tibial plateau leveling osteotomy (TPLO) plate in maintaining the postoperative tibial plateau angle (TPA) in giant-breed dogs weighing > 50 kg and to report the associated complications.
ANIMALS
Canine patients weighing > 50 kg that underwent TPLO stabilized with a locking 3.5/4.0-mm jumbo TPLO plate between January 2017 and May 2022.
METHODS
Retrospective case series retrieving postoperative outcomes from the medical records. Healing scores and TPAs were calculated using postoperative and recheck radiographs. Owner-perceived outcomes were obtained via questionnaire.
RESULTS
24 stifles in 22 dogs were included. Postoperative complications were recorded in 11 of 24 cases (45.8%) inclusive of 1 minor, 1 catastrophic, and 9 major complications. A statistically significant increase in TPA over the convalescent period was found. Grade 4 healing was present in 18 of 24 (75%) stifles, while the remainder were scored as grade 3.
CLINICAL RELEVANCE
The use of a locking 3.5/4.0-mm jumbo TPLO plate did not prevent a statistically significant increase in TPA through convalescence. This procedure displayed an unacceptably high complication rate when compared with contemporary literature of TPLO. Despite a high complication rate in this patient population, most complications were successfully managed with medical and/or surgical treatment, and high mean and median healing scores were achieved at the radiographic recheck. Additionally, owner-perceived long-term outcomes were excellent.
Abstract
Geriatric horses have a high prevalence of dental disease, which is a culmination of age-related dental changes and dental disease throughout the life of the horse that may have long-term consequences. Wear abnormalities, diastemata with periodontal disease, pulpitis and endodontic disease, infundibular caries, and equine odontoclastic tooth resorption and hypercementosis become more prevalent with age. Recognition of age-related dental disease at an early stage can help to treat and possibly preserve teeth for longer. With a natural decrease in masticatory efficiency, it is even more important to preserve teeth where possible and prevent any painful dental disease. Regular routine dental examination and maintenance will help to prevent many dental conditions such as wear disorders and possibly secondary diastemata. Successful treatment and management of most dental diseases are possible even in older patients and will ensure that we are able to maintain a high standard of welfare as horses age.
Abstract
OBJECTIVE
With 47 states experiencing a federally recognized veterinary shortage, it is important to identify areas of need and an evidence-based strategy for solving this complex problem.
SAMPLE
478 graduates of the Auburn University College of Veterinary Medicine
METHODS
First destination outcomes for graduates from the Auburn University College of Veterinary Medicine DVM classes of 2019 to 2022 (n = 478) were examined. Logistic regression and latent class analysis were conducted to identify variables that can predict a graduate’s choice of employment in rural, food animal versus other employment settings.
RESULTS
Results indicate that a graduate’s community of origin (rural, suburban, urban), preferred community, and gender have the strongest relationships with choice of employment setting (location and type).
CLINICAL RELEVANCE
These findings can be used to influence admissions practices by colleges of veterinary medicine to shape the demographics of veterinary classes and the potential practice location and types of veterinary graduates.
