RESUMEN
OBJECTIVE: To evaluate temporal changes in serum C-reactive protein (CRP) and haptoglobin (Hp) concentrations in dogs with pulmonary coccidioidomycosis and assess their utility to detect remission. METHODS: 31 client-owned dogs with newly diagnosed pulmonary coccidioidomycosis from October 2020 to February 2021 were included in a retrospective cohort study that utilized archived serum. Serum was originally obtained at diagnosis and once every 3 months after antifungal administration until either remission or 12 months. Time points were designated as baseline (T0), 3 months (T1), 6 months (T2), 9 months (T3), and 12 months (T4). Serum CRP and Hp were measured at a reference laboratory with ELISA assays. RESULTS: Median serum CRP and Hp concentrations decreased from T0 (CRP, 56 mg/L; Hp, 716.1 mg/dL) to T1 (CRP, 3.3 mg/L; Hp, 240.5 mg/dL); subsequent decreases were not significant. Eighteen (60%) and 16 (53%) of 30 dogs had normal serum CRP and Hp concentrations at T1, respectively. Absolute serum CRP (AUC, 0.58; 95% CI, 0.45 to 0.72) and Hp (AUC, 0.65; 95% CI, 0.52 to 0.78) were poor detectors of remission. However, the percentage change in Hp from T0 to T1 (AUC, 0.90; 95% CI, 0.74 to 1.0) was an excellent predictor of remission within 12 months. CONCLUSIONS: Serum CRP and Hp concentrations decrease in the first 3 months of antifungal treatment in dogs with pulmonary coccidioidomycosis, and the percentage change of Hp may help predict dogs that will achieve remission within 12 months of treatment. CLINICAL RELEVANCE: Serum CRP and Hp may be useful adjunctive biomarkers to monitor treatment response in dogs with pulmonary coccidioidomycosis.

Human patients with type 1 diabetes mellitus (T1DM) are susceptible to several long-term complications that are related to glycemic control and immune dysregulation. Immune function remains relatively unexplored in dogs with naturally occurring diabetes mellitus (NODM). Calcitriol improves various aspects of immune function in a variety of species, but its effect in diabetic dogs remains unexplored. Therefore, the objectives of this study were to (i) evaluate immune function in dogs with NODM and determine if differences exist based on the level of clinical control and (ii) assess the immunomodulatory effects of calcitriol. Twenty diabetic dogs (clinically controlled, n = ten, not controlled, n = ten) and 20 non-diabetic, healthy control dogs were included in this prospective, case-control study. Whole blood was incubated with calcitriol (10-7 M) or negative control, after which the samples were divided for phagocytosis and leukocyte cytokine response experiments. The phagocytosis of opsonized Escherichia coli (E. coli) was evaluated with flow cytometry. The samples for leukocyte cytokine response evaluations were stimulated with lipopolysaccharide (LPS), lipoteichoic acid (LTA), or phosphate buffer solution (PBS; negative control), and tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-8, and IL-10 were measured in supernatant using a canine-specific multiplex bead-based assay. The leukocytes from diabetic dogs produced higher concentrations of IL-10 (p = 0.01), IL-6 (p < 0.0001), and IL-8 (p < 0.0001) than the control dogs while controlling for the intervention and stimulant. Calcitriol decreased the supernatant concentrations of TNF-α (p < 0.001) and IL-8 (p = 0.04) with concomitant increases in IL-6 (p = 0.005). Diabetic dogs had a lower percentage of leukocytes undergoing phagocytosis (p < 0.0001) but a higher number of bacteria phagocytized per cell (p = 0.001) when compared to the control dogs. Calcitriol had no effect on phagocytic capacity. Lastly, the status of clinical control in diabetic dogs did not yield differences in immune function. These results support that dogs with NODM exhibit immune dysregulation and warrant additional investigation.
RESUMEN
OBJECTIVE: To compare results from 2 previously published surveys aimed at determining how pyometra is treated in high-quality, high-volume spay-neuter clinics (HQHVSNCs) and private practices (PPs), with a specific focus on identifying opportunities for partnership between the clinic types to improve access to care in pyometra treatment. SAMPLE: Responses from 123 PPs and 87 HQHVSNCs. METHODS: A previously published survey of PPs conducted from June to July 2021 and a similar previously published survey of HQHVSNCs conducted from June to July 2020 were compared regarding demographics, pyometra treatment availability, estimated outcome, alternative outcome, disruption, cost, and protocol between HQHVSNCs and PPs. A comparison was also run of the surveys' responses regarding referral of a pyometra to an HQHVSNC by a PP. RESULTS: Although PPs estimated that economic euthanasia is the most likely alternative outcome for 13% of patients unable to access care at their practice, 80% would be reluctant to refer to an HQHVSNC. The 3 primary reasons indicated by PPs with a reluctance to refer were a perceived lack of prompt appointment availability (20%), lack of aftercare (18%), and lack of adequate equipment (14%). In contrast, most HQHVSNCs estimated that they generally accept referrals the same day (50%) or the next day (30%) and 95% of HQHVSNCs reported having the resources needed to treat most pyometras. CLINICAL RELEVANCE: There are several opportunities for partnership between PPs and HQHVSNCs in the treatment of pyometra. The most frequent concerns expressed by PPs regarding referral to HQHVSNCs were not shared by HQHVSNCs or could be ameliorated by referral to an HQHVSNC for surgery and transfer back to the PP for aftercare.

OBJECTIVE: To identify prognostic indicators and inflammatory markers associated with nonsurvival in dogs with gallbladder mucoceles (GBMs) following cholecystectomy and to evaluate C-reactive protein (CRP) and haptoglobin concentrations in dogs with GBMs compared to healthy controls. ANIMALS: 25 dogs that underwent cholecystectomy for removal of GBM and 20 healthy control dogs. METHODS: A prospective, multicenter cohort study. Survival outcomes to hospital discharge and 2 weeks postdischarge were recorded from medical records. Laboratory variables, inflammatory markers (CRP and haptoglobin), and 25-hydroxyvitamin(OH) D (25[OH]D) concentrations were measured preoperatively. Associations between signalment, clinicopathologic variables, acute patient physiologic and laboratory evaluation (APPLEFAST) scores, inflammatory markers, 25(OH)D concentration, and survival were analyzed using logistic regression. RESULTS: 76% (19/25) and 68% (17/25) of dogs survived to hospital discharge and 2 weeks postdischarge, respectively. For each additional year of age, the odds of nonsurvival in hospital and 2 weeks postdischarge increased by 2.2 (P = .01; 95% CI, 1.2 to 5.0) and 1.7 (P = .04; 95% CI, 1.0 to 3.2), respectively. Intraoperative systolic blood pressure ≤ 65 mm Hg increased the probability of nonsurvival in hospital (P < .04). Gallbladder perforation, APPLEFAST scores, and preoperative serum concentrations of CRP, haptoglobin, and 25(OH)D were not associated with survival. Serum CRP and haptoglobin concentrations were greater in dogs with GBM compared to controls (P < .001). CLINICAL RELEVANCE: Increasing age and intraoperative systolic blood pressure ≤ 65 mm Hg were associated with nonsurvival in dogs with GBM undergoing cholecystectomy. Serum CRP, haptoglobin, and 25(OH)D were not associated with nonsurvival postcholecystectomy in this sample population.

OBJECTIVES: Hypothermia is a common complication of anesthesia, particularly in cats. Some veterinarians insulate the extremities of cats as a preventive measure, and there is evidence that heating the extremities of dogs decreases the rate of heat loss from the core. This study investigated whether active warming or passive insulation of the extremities of cats resulted in a slower decrease in rectal temperature during anesthesia. METHODS: Female cats were assigned via block randomization to passive (cotton toddler socks), active (heated toddler socks) or control group (uncovered extremities). Rectal temperature was monitored every 5 mins from induction through return to trap/carrier (final temperature). Multivariable linear regression models were used to compare temperature (rate change and final) between groups. RESULTS: There were 164 cats with 1757 temperature readings. Mean total duration of anesthesia was 53 ± 13 mins. The temperature of all groups decreased linearly over time (all P <0.0001), with the rates of temperature decrease being -0.039°F/min (95% confidence interval [CI] -0.043 to -0.035)/-0.022°C (95% CI -0.024 to -0.019), -0.039°F/min (95% CI -0.042 to -0.035)/-0.022°C (95% CI -0.023 to -0.019) and -0.029°F/min (95% CI -0.032 to -0.025)/-0.016°C (95% CI -0.018 to -0.014) for the control, passive and active groups, respectively. The control, passive and active groups had median final temperatures of 98.4°F (interquartile range [IQR] 97.6-99.4)/36.9°C (IQR 36.4-37.4), 98.0°F (IQR 97.2-98.7)/36.7°C (IQR 36.2-37.1) and 99.1°F (IQR 97.7-100.0)/37.3°C (IQR 36.5-37.8), respectively. After controlling for weight, postinduction temperature and duration of anesthesia, and as compared with controls, the final temperature of the active group was predicted to be 0.54°F (95% CI 0.03-1.01)/0.3°C (95% CI 0.02-0.56) greater (P = 0.023), while the passive group was not significantly different (P = 0.130). CONCLUSIONS AND RELEVANCE: The rate of rectal temperature decrease was significantly slower for the active group compared with the other groups. Although the cumulative difference in final temperature reading was modest, superior materials might enhance performance. Cotton toddler socks alone did not slow the rate of temperature decrease.

BACKGROUND: Clinicopathologic variables predictive of disseminated coccidioidomycosis are known in humans but have not been explored in dogs. Serum 25-hydroxyvitamin (OH)D correlates with severity of disease of various etiologies in dogs but its role in coccidioidomycosis is unknown. OBJECTIVE: Determine whether serum 25(OH)D concentrations are different in dogs with coccidioidomycosis compared with healthy controls and if clinicopathologic variables are associated with extent of disease. ANIMALS: Thirty-five dogs with coccidioidomycosis (pulmonary, n = 13; disseminated, n = 15; uncharacterized, n = 7), and 25 healthy control dogs. METHODS: Prospective cohort study. Serum 25(OH)D and C-reactive protein (CRP) concentrations were measured with modified-HPLC and a commercial ELISA kit, respectively. RESULTS: There was no difference in 25(OH)D concentrations between dogs with coccidioidomycosis (median, interquartile range [IQR]; 31.9 ng/mL, 23.3-49.2) and controls (29.5 ng/mL, 25.6-40.8, P = .73). Serum 25(OH)D concentration was lower in dogs with coccidioidomycosis and IgG titers ≥1:32 than dogs with titers below this cut-off (P = .02). Dogs with IgG titers ≥1:32 were more likely to have disseminated disease (OR, 7.5; 95% CI: 1.1-68; P = .03). Serum CRP concentrations were higher in dogs with IgG titers ≥1:16 (median, IQR; 4474.8 ng/mL, 2885.8-8236.1) than in those below this cut-off (151.2 ng/mL, 30.4-2907.3; P = .02). There was a significant inverse association between serum 25(OH)D and CRP at 25(OH)D concentrations ≤33 ng/mL. CONCLUSION AND CLINICAL IMPORTANCE: Serum 25(OH)D concentration was lower for dogs with IgG titers ≥1:32, indicating a potential association between semi-quantitative titers and 25(OH)D concentrations in dogs with coccidioidomycosis. IgG titers ≥1:32 yielded higher odds of disseminated disease, but was inadequate as a standalone test to determine form of disease.

BACKGROUND: Albuterol by inhalation (IH) is a common treatment for hyperkalemia in humans but its effect on blood potassium concentrations in dogs is unknown. OBJECTIVE: Determine whether albuterol (IH) decreases blood potassium concentrations in healthy normokalemic dogs and if effects are dose-dependent. ANIMALS: Ten healthy dogs. METHODS: Prospective, crossover experimental study. Albuterol sulfate was administered at a low-dose (90 µg) in phase I and, 7 days later, high-dose (450 µg) in phase II. Blood potassium and glucose concentrations (measured via blood gas analyzer) and heart rates were obtained at baseline and then 3, 5, 10, 15, 30, 60, 90, 120, 180, and 360 minutes after inhaler actuation. RESULTS: Blood potassium concentrations decreased rapidly after albuterol delivery with a significant reduction compared to baseline within 30 minutes in both phases (P = .05). The potassium nadir concentration of phase I occurred at 60 minutes (mean, SD; 4.07 mmol/L, 0.4) and was significantly decreased from baseline, (4.30 mmol/L, 0.3; t(9) = 2.40, P = .04). The potassium nadir concentration of phase II occurred at 30 minutes (mean, SD; 3.96 mmol/L, 0.39) and was also significantly decreased from baseline, (4.33 mmol/L, 0.4; t(9) = 2.22, P = .05). The potassium nadir concentration decreased by 0.1 mmol/L for each 10 µg/kg increase in dose of albuterol (P = .01). Five dogs had ≥1 hyperglycemic measurement (ie, >112 mg/dL). No median heart rate was tachycardic nor was any mean blood glucose concentration hyperglycemic at any time point. CONCLUSION AND CLINICAL IMPORTANCE: Albuterol IH decreases blood potassium concentrations in a dose-dependent manner without clinically meaningful alterations to heart rate or blood glucose concentrations in healthy dogs. The mean decrease in potassium concentration at the high-dose of albuterol was modest (0.38 mmol/L).

Current management practices of pyometra in the private practice setting are not well documented. The goal of this study was to understand pyometra management in the private practice setting, and the current relationship private practices have with high quality, high volume, spay-neuter (HQHVSN) clinics regarding referral for pyometra surgery. An anonymous electronic survey was piloted and distributed using SurveyMonkey via email, social media, and the Independent Veterinary Practitioners Association targeting veterinarians who see companion animals. A total of 153 responses were received from June to July 2021, with respondents distributed throughout the United States. Practices performed a median of 10 spay and neuters per week, with the median spay cost being $350 (IQR 250-500) for dogs and $250 (IQR 180-350) for cats. The median cost of a pyometra surgery was $1000 (IQR 700-1500) for dogs and $750 (IQR 450-1000) for cats. All practices treated pyometra at least sometimes, despite the disruption (major 19%, moderate 47%, mild 29%, none 5%) to their day. All pyometra presentations were accepted for treatment at least sometimes: BAR/QAR (98%), depressed or non-ambulatory (88%), and obtunded or lateral (62%) with mean estimated survival of 96%, 74%, and 31%, respectively. The majority (56%) of clients were reported to sometimes have trouble paying for all recommended services, while it was less often reported that clients often (31%) or rarely (13%) had trouble. Private practices willing to refer only did so always 20% of the time and sometimes 36% of the time. Private practices will do what they can to treat most pyometras that present at their practice within a timely manner before referring elsewhere. There is currently inconsistent utilization of HQHVSN clinics as a potential referral resource due to location or appointment availability.

Modern animal shelters are encouraged to adopt "best practices" intended to promote life-saving for the animals that enter their systems. While these best practices have been defined and widely promoted within the profession, few studies have tracked how making the recommended changes affects live release rates (LRR) and other shelter metrics. In 2017, the municipal animal shelter in Memphis, TN (Memphis Animal Services) implemented five new strategies and analyzed their resultant life-saving data. The interventions included managed strategic shelter intake, pet owner safety net, community cat return to field, transition of field services from punitive to assistive, and streamlined adoption and transfer protocols. The median LRR for cats prior to 2017 was 35% (IQR 22, 36). After the intervention, the LRR increased to a median of 92% (IQR 92, 94). The correlation between intake and euthanasia for cats prior to the intervention was significant (P < 0.001) and very strong (r = 0.982), while after there was no relationship (-0.165) and it was not significant (P = 0.791). The median LRR for dogs prior to 2017 was 25% (IQR 19, 48). After the intervention, the LRR increased to a median of 87% (IQR 86, 88). The correlation between intake and euthanasia for dogs prior to the intervention was significant (P < 0.001) and very strong (r = 0.991), while after there was a moderate relationship (-0.643) that was not significant (P = 0.242). The median LRR for kittens prior to 2017 was 34% (IQR 23, 38), which increased (P = 0.001) to 92% (IQR 91, 92) after intervention. The percent of kittens entering the shelter with an outcome of euthanasia decreased (P < 0.001), from a median of 59% (IQR 54, 73) to a median of 3% (IQR 1, 3). The median return to owner (RTO) rate for dogs increased (P = 0.007) from 10% (IQR 9, 11) to 13% (IQR 13, 13). Implementation of these best practices accelerated Memphis Animal Services' progress toward a live release rate of at least 90%, particularly for cats, dramatically decreased kitten euthanasia, increased the RTO rate for dogs and severed the historical correlation between euthanasia and intake.
RESUMEN
OBJECTIVES: Ear-tipping practices and the meaning of the ear tip in trap-neuter-return (TNR) programs have not been well documented. The purpose of this study was to report the frequency of common ear-tipping practices in the USA, to identify the most effective methods and to establish a foundation for ear-tipping practice standards. METHODS: An anonymous 24-question survey was advertised from 4 to 20 October 2021 to individuals who participate in TNR programs that routinely perform ear tipping. RESULTS: There were 526 survey responses from individuals who participate in TNR programs, of whom 410 completed the survey. For ear-tip meaning, nearly 100% of respondents indicated that an ear tip meant that a cat had been sterilized. Several respondents answered that it also indicated rabies vaccination or socialization status, with 92 (22%) selecting both, 79 (19%) selecting rabies only and 50 (12%) selecting unsocial only. The majority of respondents tipped the left ear (81%), used a visual estimate to determine the cut (92%) and described the ideal silhouette as straight across (92%). The median percentage of cats where ear tips bled after initial hemostasis was 5% (interquartile range [IQR] 2-10), and the median percentage of negative feedback regarding the ear tip was 1% (IQR 0-5). In terms of weighted rank order, the most common feedback was that too much ear tip was removed (5.5), followed by a cat being ear tipped in error (4.7), persistent bleeding (4.2) and not enough ear tip being removed (4.2). Responses revealed heterogeneity regarding technique for both excision and hemostasis, as well as personnel performing the procedure. There were no significant associations between techniques and bleeding or negative feedback. CONCLUSIONS AND RELEVANCE: There is variation in the methods for performing an ear tip, as well as what an ear tip signifies. Standards for this procedure would be helpful.

BACKGROUND: Gallbladder mucocele (GBM) is a common biliary disorder in dogs that can be categorized into 6 types, but the value of this classification scheme remains unknown. Cholecystectomy is associated with high death rates and warrants additional interrogation. OBJECTIVES: Investigate the clinical value of ultrasonographic diagnosis of type of GBM and identify prognostic factors in dogs with GBM undergoing cholecystectomy. ANIMALS: Two hundred sixteen dogs. METHODS: Retrospective cohort study. Dogs with GBM diagnosed from 2014 to 2019 at 6 veterinary referral hospitals in Asia. Ultrasonogram images were reviewed and a GBM type (ie, types I-VI) assigned. RESULTS: Dogs with GBM type V as compared to I (OR, 8.6; 95% CI, 2.6-27.8; P < .001) and III (OR, 10.0; 95% CI, 2.5-40.8; P = .001), and dogs with type VI compared to I (OR, 10.5; 95% CI, 1.8-61.2; P = .009) and III (OR, 12.3; 95% CI, 1.8-83.9; P = .01) were more likely to exhibit signs of biliary tract disease. Independent predictors of death after cholecystectomy included age (OR, 2.81; 95% CI, 1.41-5.59; P = .003) and intraoperative systolic blood pressure (SBP) nadir. There was an interaction between SBP nadir and gallbladder rupture; SBP nadir in dogs with (OR, 0.92; 95% CI, 0.89-0.94; P < .001) and without (OR, 0.88; 95% CI, 0.82-0.93; P < .001) gallbladder rupture. CONCLUSION AND CLINICAL IMPORTANCE: Increasing developmental stage of GBM could be associated with an increased likelihood of biliary tract related clinical signs. Nadir SBP deserves further investigation as a prognostic or potentially modifiable variable, particularly in the presence of gallbladder rupture.

To determine whether two immediately postoperative preventive procedures, dilute epinephrine (1:400,000) as a scrotal wash or application of controlled mechanical pressure to the scrotum, reduce the risk or severity of scrotal hematoma following routine castration. Male cats with two descended testicles presenting to Midwestern University's Trap Neuter Return program were eligible for inclusion. Cats were assigned via block randomization to control, dilute epinephrine wash, or controlled mechanical pressure groups. For the epinephrine group, 0.2 ml (0.008 mg) of epinephrine diluted with sterile saline was instilled inside the scrotum. In the case of mechanical pressure, a broad-based clip generating less than 0.5 kg of pressure was applied for 10 minutes. Cats were evaluated for scrotal hematoma and the need for treatment by a veterinarian blinded to treatment group. Multivariable logistic regression was used to determine if the incidence of scrotal hematoma or scrotal hematoma requiring treatment was different between groups while controlling for other variables. There were 276 cats with a median age of 30 months (IQR 12,48) and a mean weight of 3.5 kg (SD 1.2). Scrotal hematomas were noted in 15 of the 92 (16%) control cats, as compared with 12 of the 92 (13%) epinephrine and nine of the 92 (10%) pressure cats. Treatment was required for 10 (67%) control, six (50%) epinephrine, and three (33%) pressure hematomas. Regression demonstrated a decreased risk of scrotal hematoma requiring treatment for cats in the pressure group (ORâ¯=â¯0.2, Pâ¯=â¯.044) controlling for weight (ORâ¯=â¯2.2, Pâ¯=â¯.006) and surgical duration (ORâ¯=â¯1.1, Pâ¯=â¯.026). Weight was the only significant variable for the presence of scrotal hematoma (ORâ¯=â¯2.2, P < .0001). Controlled mechanical pressure applied immediately after routine castration can help decrease the proportion of scrotal hematomas that require treatment.

In a frequently cited 2005 paper, a Ricker model was used to assess the effectiveness of trap-neuter-return (TNR) programs for managing free-roaming domestic cat populations. The model (which was originally developed for application in the management of fisheries) used data obtained from two countywide programs, and the results indicated that any population reductions, if they existed, were at best modest. In the present study, we applied the same analysis methods to data from two long-term (i.e., >20 years) TNR programs for which significant population reductions have been documented. Our results revealed that the model cannot account for some key aspects of typical TNR programs, and the wild population swings it predicts do not correspond to the relative stability of free-roaming cat populations. A Ricker model is therefore inappropriate for use in assessing the effectiveness of TNR programs. A more recently developed, stochastic model, which accounts for the movement of cats in and out of a given area, is better suited for predicting the sterilization effort necessary to reduce free-roaming cat numbers through TNR programs.
RESUMEN
OBJECTIVES: Isopropyl alcohol 70% as a rinse agent for chlorhexidine scrub has been shown to decrease body temperature more quickly than chlorhexidine solution in mice prepared aseptically prior to surgery. For this reason, some high-quality, high-volume (HQHV) surgical sterilization clinics use chlorhexidine solution rather than alcohol. We sought to determine if temperature upon entry to recovery, heat loss per kg and rate of temperature decline during surgery were different between cats rinsed with chlorhexidine solution vs 70% isopropyl alcohol following surgical scrub, and if there were significant predictors of recovery temperature. METHODS: Female cats admitted for surgery to trap-neuter-return (TNR) clinics at a veterinary college were assigned chlorhexidine solution or alcohol rinse agents via block randomization. Veterinary students and veterinarians performed spay surgeries using HQHV techniques. In recovery, heat support and reversal agents were available for cats with a low body temperature or that were slow to recover. Baseline values, outcome variables and duration of each stage (preparation, surgery, recovery) were assessed using Wilcoxon rank-sum and t-tests. Recovery temperature was evaluated using random effects multiple linear regression. RESULTS: The recovery temperature, heat loss per kg, heat loss per min, need for reversal and need for heat support in recovery were not significantly different between rinse groups. Weight <2.3 kg, body condition score <4, duration of surgery and postinduction temperature were predictors of recovery temperature. The rate of heat loss in the first 30 mins of surgery was slightly lower for cats in the alcohol rinse group and the recovery duration was shorter for cats weighing less <2.3 kg in the alcohol rinse group. CONCLUSIONS AND RELEVANCE: There were no clinically meaningful differences in body temperature between chlorhexidine and alcohol rinses. Both chlorhexidine solution and isopropyl alcohol 70% are appropriate rinse agents for aseptic preparation of feline spay surgeries.

The Midwestern University College of Veterinary Medicine hosts student-run free clinics that offer surgical sterilization of male and female dogs and cats, with the goal of 20 surgical cases per clinic. Surgical complexity varies significantly between the surgical procedures for males (castration) and females (ovariohysterectomy) and is also influenced by weight and age for dogs. A surgical complexity scoring system was implemented to ensure the minimum number of patients while providing a diverse mix of cases. The aim of this study was to determine whether the surgical complexity scoring system accurately predicted procedure duration. Surgical records were collected between August 2016 and October 2019. Points (1-5) were assigned to each patient at the time of appointment based on species, sex, additional procedure, age and weight, and the schedule was targeted for 50 points. Each point was predicted to account for 15 minutes of surgical time. The duration for each point category was assessed via rank-sum against the predicted median. Sixteen clinics occurred during the study period, having a mean of 40.4 points and 17 patients, 29.5 (74%) of which were allocated to students. There were 264 surgeries, with 241 (91%) having complete start and end times. Surgical duration for student surgeries was not different from the estimate for each point category, with the exception of 2-points, which had a median 5.0 minutes longer than anticipated (p = .0004). The surgical complexity scoring system is an effective tool to optimize scheduling of educational spay/neuter mobile clinics.

BACKGROUND: In recent years, marijuana has become legal for use in many states, for either medicinal or recreational purposes. Objective: The primary objective is to determine if legalization of medical marijuana is associated with an increased use among trauma patients. Methods: Prospective observational study included three periods; (pre-legalization; period 1); legal to grow for medicinal purposes but no dispensaries open (period 2); and legal to purchase medicinal marijuana in a dispensary (period 3). The study included all adult trauma patients presenting to an urban level I trauma center in Phoenix, AZ. The prevalence of use (as defined by positive urine drug screen or self-reporting) in each time period was determined and compared using two sample tests of proportion. Confidence intervals for prevalence (self-reporting only) were compared with published age matched data from the same geographical region of the general population. Results: The prevalence of marijuana use increased significantly from pre-legalization (period 1) to post legalization (periods 2 and 3), but there was no significant change between the two post legalization periods. After controlling for age and sex, the odds of being marijuana positive post-legalization vs. pre-legalization was 1.36, p = 0.006 95%CI [1.09-1.7]. Overall, the prevalence of marijuana among trauma patients was nearly four-fold higher than the population as a whole in the same geographic region. Patients who use marijuana are more likely to use cocaine or amphetamine (OR 2.31; 95% CI 1.86-2.89) or had an ethanol level above 80 mg/dL (OR 1.57; 95% CI 1.32-1.87). Conclusion: The legalization of medicinal marijuana is associated with significantly increased prevalence among trauma patients. It appears that legalization, rather than the convenience of dispensaries, is associated with an increase in use.

BACKGROUND: Hypovitaminosis D is a risk factor for the development of respiratory infections in humans and repletion can be protective. OBJECTIVES: Determine if serum 25-hydroxyvitamin (OH)D concentrations are lower in shelter dogs and if 25(OH)D concentrations are associated with clinical signs of canine infectious respiratory disease complex (CIRDC) or with time in the shelter. ANIMALS: One hundred forty-six shelter dogs (clinically ill n = 36, apparently healthy n = 110) and 23 nonshelter control dogs. METHODS: Prospective cohort study. Shelter dogs were grouped as clinically ill or apparently healthy based on the presence or absence, respectively, of clinical signs associated with CIRDC. Serum 25(OH)D concentrations were measured with a competitive chemiluminesence immunoassay. Nucleic acids of agents associated with the CIRDC were amplified by polymerase chain reaction assays. RESULTS: The concentration of 25(OH)D was 7.3 ng/mL (4.5-9.9, 95% confidence interval [CI]) lower in dogs with signs of CIRDC than apparently healthy shelter dogs (t(142) = 2.0, P = .04). Dogs positive for DNA of canine herpesvirus (CHV)-1 had serum 25(OH)D concentrations 14.9 ng/mL (-3.7 to 29.6, 95% CI) lower than dogs that were negative (t(137) = 2.0, P = .04). Serum 25(OH)D concentrations in shelter dogs were not different from control dogs (t(45) = -1.4, P = .17). Serum 25(OH)D concentration was not associated with duration of time in the shelter (F(1, 140) = 1.7, P = .2, R2 = 0.01). CONCLUSION AND CLINICAL IMPORTANCE: Vitamin D could have a role in acute respiratory tract infections in shelter dogs.

Pyometra management in the high quality, high volume spay-neuter (HQHVSN) environment is not well documented. The goal of this study was to identify pyometra management practices and patient outcomes in the HQHVSN environment. An electronic survey was piloted and distributed to HQHVSN clinics using Survey Monkey via email lists and social media. A total of 118 responses were received from June to July 2020. Respondents were distributed across the United States with the majority of clinics associated with a shelter (75%). Clinics performed a median of 25 spays and neuters per day and 5000 per year. Most clinics (86%) were willing to treat nonincidental pyometras at least sometimes, and nearly all of these clinics (97%) were willing to accept pyometra referrals. Of these clinics, nearly all (95%) felt they had the necessary resources to treat most pyometras that presented and that a pyometra case was only modestly disruptive to their surgery flow. Most clinics (70%) charged a fee for treatment, charging a median of $200 for dogs and $125 for cats. This is much lower as compared to the estimated ranges for private practice ($600-$2500) and emergency hospitals ($1500-$3579). The majority of patients that HQHVSN clinics accepted for treatment were seen the same day (50%) or next day (42%). These clinics estimated that of the animals who presented, 76% were BAR or QAR, 20% were depressed or nonambulatory, and 4% were obtunded and lateral. Estimated survival for these treated groups were 98%, 80%, and 38%, respectively. HQHVSN clinics may represent a resource for treating pyometras when treatment is disruptive to the schedule of a private practice or clients present with financial limitations. There is an opportunity for HQHVSN and private practice to form a partnership to leverage the strengths of both models and improve access to care for pets.

Despite recent growth in the field of shelter medicine, there is a paucity of wage data available. Understanding determinants of salary is helpful for new graduates deciding on a career path as well as employees and employers with regard to budgeting, professional development, and negotiations. An anonymous online survey was distributed via commercial survey platform to shelter veterinarians. Salary was analyzed using multiple linear regression, Kruskall-Wallis equality-of-populations rank-test, and Conover-Iman pairwise comparison. Of the 219 unique respondents, 197 worked as shelter veterinarians, with 157 full-time and 40 part-time. Fifteen respondents worked in academia, and 7 respondents worked in shelter leadership. Full-time shelter veterinarians had a median income of $92,000 [$78,000-110,000], which is the same as the median salary reported for all veterinarians by the AVMA in 2018. Salary depended on years of shelter experience (P = .004), supervision of other veterinarians (Pâ¯=â¯.015), region (Southwest, Pâ¯=â¯.010, Mideast, Pâ¯=â¯.010, and Far West, Pâ¯=â¯.002) and size of the metropolitan area (>1 million, Pâ¯=â¯.001 and <250,000, Pâ¯=â¯.011). Part-time veterinarians had a median income of $60,000 [$44,000-84,000]. The only variable predictive of salary was hours worked, with part-time veterinarians paid a median of $48 [36-66] per hour. Academic veterinarians had a median income of $108,000 [90,000-120,000]. For academics, title (assistant professor, P <.0001 and professor, Pâ¯=â¯.001), PhD (Pâ¯=â¯.010), and master's (P= .001) predicted salary. Veterinarians working in leadership positions had a median income of $120,000 [110,000-198,000], and no variable was significant. Veterinarians employed in academia and leadership had a higher salary than veterinarians employed in the shelter. There are predictors of salary for shelter medicine veterinarians, which will help both potential employers and employees, determine reasonable salaries when budgeting, negotiating, or planning personal development.

According to American Veterinary Medical Association statistics, veterinarians employed in the not-for-profit sector account for the smallest group by type of employment. However, this group has experienced the greatest amount of change, with an increase of 52% between 2008 and 2013 and 55% between 2013 and 2018. Despite this growth, there has been a paucity of information regarding the salary, benefits, hours, and job duties that come with a career in shelter medicine. An initial survey of shelter medicine salary, benefits, hours, and job duties was conducted in 2011, and a similar survey conducted in 2018. All responses were anonymous. Results from 2018 were compared to 2011 using 2 sample test of proportions (counts) or Mann-Whitney (Wilcoxon rank sum) test (medians). A total of 207 conforming responses were received in 2011, and 219 in 2018. Median salary for all full-time veterinarians in the field of shelter medicine was $75,000 (interquartile range [IQR], 65,000-85,000) in 2011 and $94,500 (IQR, 80,000-110,000) in 2018. Part-time shelter employed veterinarians in 2011 worked a median of 20 hours (IQR 7-28) for an hourly rate of $41 (IQR, 29-56) while they worked a median of 26 hours (IQR, 15-32) for an hourly rate of $48 (IQR, 36-66) in 2018. There was an increase in the provision of all categories of benefits and an increase in veterinarians employed in academia and leadership. Demographics were similar, with the exception of increases in the number of boarded specialists and veterinarians who had completed a residency. Veterinarians reporting that shelter medicine had been offered in their curriculum increased by 44%. Budgets for shelters were reported to be higher, while animal intake and daily count of animals in care was lower. Comparison between surveys of shelter medicine veterinarians in 2011 and 2018 showed a consistent increase in salary, benefits and resources. There were indicators that the field of shelter medicine has matured as a discipline, particularly with regard to the availability of shelter medicine education and increased number of boarded specialists.
