Abstract
OBJECTIVE
To examine the risk of developing an overweight or obese (O/O) body condition score (BCS) in gonadectomized versus intact dogs and, separately, the impact of age at gonadectomy on O/O outcomes among sterilized dogs.
ANIMALS
Dogs were patients of Banfield Pet Hospital in the US from 2013 to 2019. After exclusion criteria were applied, the final sample consisted of 155,199 dogs.
PROCEDURES
In this retrospective cohort study, Cox proportional hazards models evaluated associations between O/O and gonadectomy status, sex, age at gonadectomy, and breed size. Models were used to estimate the risk of becoming O/O in gonadectomized versus intact dogs and, separately, to estimate risk of O/O BCS according to age at surgery among gonadectomized dogs.
RESULTS
Gonadectomy increased O/O risk for most dogs compared to intact dogs. Unlike most prior findings, O/O hazard ratios among gonadectomized versus intact dogs were larger for males than females. O/O risk varied according to breed size but not linearly. Sterilizing at 1 year old tended to yield a lower O/O risk compared to doing so later. Comparative O/O risk among dogs gonadectomized at 6 months versus 1 year varied by breed size. Overall patterns for obesity related to size were similar to patterns in the O/O analysis.
CLINICAL RELEVANCE
Veterinarians are uniquely positioned to help prevent O/O in their patients. Results extend understanding of risk factors for O/O development in dogs. In combination with information about other benefits and risks associated with gonadectomy, these data can help tailor recommendations regarding gonadectomy in individual dogs.
Abstract
OBJECTIVE
To evaluate the efficacy and safety of bromelain to control pain and inflammation in cats undergoing ovariohysterectomy.
ANIMALS
30 client-owned cats undergoing ovariohysterectomy.
PROCEDURES
In a randomized, blinded clinical study, cats were assigned to receive either oral bromelain suspension (40 mg/kg [18 mg/lb]; BG, n = 15) or placebo solution (0.1 mL/kg [0.045 mL/lb]; PG, 15), which were administered 90 minutes before and 12 hours after surgery. The anesthetic protocol included acepromazine, meperidine, propofol, and isoflurane. Pain and sedation were assessed at various time points up to 24 hours post-extubation using the UNESP-Botucatu multidimensional composite pain scale, the Glasgow feline composite measure pain scale, and a descriptive numerical scale. Surgical wound inflammation was measured at the same time points, using a numeric rating scale. Morphine was administered as rescue analgesia. Laboratory data (urea, creatinine, gamma-glutamyl transferase, alkaline phosphatase, the prothrombin time, and the fecal occult blood) were analyzed preoperatively and 24 hours after surgery.
RESULTS
Pain/inflammation scores, and analgesic requirements did not differ between groups. Shorter recovery time and lower sedation scores were recorded during the first hour post-extubation in the BG than the PG. Postoperatively, serum creatinine and gamma-glutamyl transferase were lower in the BG compared to PG. Compared to baseline values, all biochemistry variables decreased at 24 hours in the BG. The prothrombin time and fecal occult blood did not differ between groups or over time.
CLINICAL RELEVANCE
Bromelain did not provide significant analgesic and anti-inflammatory benefits over placebo in cats undergoing ovariohysterectomy.
Abstract
Objective
To characterize clinician preferences and justification for preferred methods for managing canine idiopathic acute diarrhea (IAD) and compare results to evidence-based literature.
sample
284 surveys from veterinarians in small animal first-opinion practice.
Methods
Veterinarians were asked to complete a survey (61 questions) including background demographic information, practice type and location, duration in practice, and management questions for canine IAD pertaining to nutritional, probiotic, antimicrobial, antidiarrheal, benign neglect, and other therapies. The survey was available between May 5, 2021, and August 30, 2021.
Results
Respondents reported that their preferred first-line therapy for canine IAD included dietary modification (41.3% of respondents), probiotics (20.1%), antimicrobials (21.2%), antidiarrheal medications (13.0%), and benign neglect (4.3%). The percentage of respondents who reported each therapy as either extremely effective or very effective for canine IAD varied by treatment, as follows: antimicrobials (75.2%), dietary modification (59.13%), antidiarrheal medications (42.5%), probiotics (35.5%), and benign neglect (6.52%). Perceptions of effectiveness, efficiency of treatment, and clinician justification for use were variable among treatments. Reported practice styles were occasionally in disagreement with evidence-based methods of canine IAD management.
Clinical Relevance
Current clinical management of IAD is not consistently in agreement with evidence-based recommendations. The results of this study underscore the continued need to evaluate veterinary prescribing practice trends compared to evidence-based recommendations and promote dissemination of new information.
Abstract
OBJECTIVE
To assess the agreement between measurements of total protein (TP) concentrations in canine serum samples between a commercially available veterinary digital refractometer (DR), an analog handheld refractometer (AR), and a laboratory-based chemistry analyzer (LAB). An additional objective was to assess the effects of various potential interferents (ie, hyperbilirubinemia, increased BUN, hyperglycemia, hemolysis, and lipemia) on DR measurements.
SAMPLE
108 canine serum samples.
PROCEDURES
Serum samples were measured in duplicate on the DR, which reported TP concentration, assessed via optical reflectance and critical angle measurement. These serum samples were also assessed on the AR and LAB for comparison. Serum samples with grossly visible lipemia, hemolysis, and icterus were noted. Medical records were retrospectively assessed to determine concentrations of BUN, glucose, and bilirubin.
RESULTS
Method comparisons among the various data generated by the analyzers were completed using linear regression, Bland Altman, and calculation of intraclass coefficients. Mean bias between DRTP and LABTP in samples without potential interferents was 0.54 g/dL with 95% limits of agreement of –0.17 to 1.27 g/dL. One-third of DRTP samples without potential interferents had > 10% difference from their LABTP comparison. Interferents, particularly marked hyperglycemia, can result in inaccurate measurements on the DR.
CLINICAL RELEVANCE
There was a statistically significant difference between DRTP and LABTP measurements. TP measurements in samples with any potential interferent, particularly hyperglycemia, should be assessed cautiously on DR and AR.
Abstract
OBJECTIVE
To compare complications between a modified incisional gastropexy (MIG) technique and standard incisional gastropexy (SIG).
ANIMALS
347 client-owned dogs.
PROCEDURES
Dogs that had undergone SIG or MIG from March 2005 through April 2019 were identified through a medical record search of the University of Missouri Veterinary Health Center. The MIG technique is identical to SIG except 2 additional simple interrupted sutures are added, 1 cranial and 1 caudal to the continuous suture line, going full thickness into the stomach to ensure engagement of submucosa. Medical record information was used to identify intraoperative, postoperative, and short-term complications, and telephone or email communication to pet owners and/or referring veterinarians was used to identify complications (short-term and long-term) after discontinuance of care at the University of Missouri Veterinary Health Center. Intraoperative, postoperative, short-term, and long-term complications were analyzed in aggregate within 6 matched groupings: (1) gastropexy for gastric dilatation-volvulus, (2) prophylactic gastropexy without other procedures, (3) gastropexy with ovariohysterectomy, (4) gastropexy with castration, (5) gastropexy with splenectomy, and (6) gastropexy with celiotomy other than splenectomy. Overall rates of complications potentially attributed to gastropexy were compared between SIG and MIG using the Fisher exact test. Overall rates of complications not attributed to gastropexy were compared between SIG and MIG using the χ2 test.
RESULTS
There were no significant differences in overall complication rates between SIG and MIG.
CLINICAL RELEVANCE
Surgeons who feel that engagement of gastric submucosa is important for gastropexy success may use the MIG technique with minimal fear of complications. However, superiority of one technique over the other cannot be determined on the basis of this study.
Abstract
Opportunities for the public to interact with animals in public settings such as petting zoos, fairs, and farm visits can be valuable learning and entertainment experiences. However, zoonotic disease transmission from healthy animals on exhibit and their environments, as well as injuries and other health problems, may result from these interactions if steps are not taken to minimize risks. The 2023 Compendium of Measures to Prevent Disease Associated with Animals in Public Settings provides background about these potential risks and updates recommendations for reducing those risks. Enteric zoonotic disease risks from animal contact in public settings include Shiga toxin–producing Escherichia coli infections, cryptosporidiosis, and campylobacteriosis. These infections occur when pathogens are accidentally ingested by individuals following direct contact with animals or contaminated objects. Zoonotic influenza infections can occur in a similar manner or through aerosols generated from infected animals. Other infectious diseases, parasitic infections, bites, and other injuries are also possible hazards in these settings. Inadequate handwashing and facility design flaws are frequent contributors to these risks, especially on farms or temporary exhibits not specifically designed for public use. Venues should provide sufficient handwashing stations and establish clearly defined animal contact areas. Operators should educate visitors about potential disease and injury risks, steps necessary to minimize exposure, and the importance of handwashing after the visit. Additionally, operators and visitors alike should realize that certain individuals are at heightened risk for zoonotic infections. Signs, handouts, and other educational materials are publicly available in a toolkit that accompanies the compendium.
