Pseudomonas aeruginosa isolation from dog grooming products used by private owners or by professional pet grooming salons: prevalence and risk factors.

BACKGROUND: Pseudomonas aeruginosa is the most commonly isolated bacterium from skin lesions of dogs with post-grooming furunculosis (PGF). It is frequently found in human hair and skin care products, and may pose a health risk to consumers. Information regarding the prevalence of P. aeruginosa contamination of dog grooming products is lacking. OBJECTIVES: To investigate the prevalence of P. aeruginosa contamination in nonmedicated dog grooming products after either home or professional use in pet grooming salons, and to identify risk factors that may be associated with contamination. MATERIALS AND METHODS: Of 117 bottles of grooming products sampled for bacterial culture, 97 were used by pet grooming salons and 20 were used by private individuals. The following suspected risk factors were recorded: bottle size, relative remaining volume, content dilution, expiration date and ingredient list. RESULTS: Pseudomonas aeruginosa was isolated from 14 of 117 samples [11.97%, 95% confidence interval (CI) 6.97-19.3%]. Diluted products were contaminated significantly more often compared to undiluted products (odds ratio = 15.5, 95%CI 2.05-117.23; P < 0.01). None of the other variables was significantly associated with P. aeruginosa contamination. CONCLUSIONS AND CLINICAL RELEVANCE: Pseudomonas aeruginosa contamination of dog grooming shampoos and conditioners was significantly associated with product dilution. Contaminated grooming products may predispose dogs to severe bacterial skin infections such as PGF.

Prospective evaluation of 5 urinary biomarkers as predictors of acute kidney injury in nonazotemic, hospitalized dogs.

BACKGROUND: Early recognition of acute kidney injury (AKI) is hindered by current definitions and use of traditional, insensitive markers. HYPOTHESIS/OBJECTIVES: Urinary (u) activity of γ-glutamyl transpeptidase (GGT) and alkaline phosphatase (ALP), and concentrations of heat-shock protein 70 (HSP70) and interleukins (ILs) -6 and -18, are predictive biomarkers for AKI and survival. ANIMALS: Nonazotemic, hospitalized dogs (n = 118) and healthy controls (n = 20). METHODS: A prospective observational study. Nonazotemic dogs at risk of AKI were recruited and their urinary biomarker concentrations were measured at presentation. Serum creatinine (sCr) and symmetric dimethylarginine (sSDMA) were measured daily until discharge/death. RESULTS: The overall case fatality rate was 18.6%. Fifteen dogs (12.7%) developed AKI, which was associated with death (relative risk, 3.2; 95% confidence interval [CI], 1.57-6.55). All 5 urinary biomarkers were significantly higher in hospitalized dogs compared to controls, with minimal overlap. uHSP70/uCr, uGGT/uCr, and uIL-6/uCr at presentation were higher in dogs which later developed AKI. Areas under the receiver operator characteristic curve (AUROC) (95% CI) for the 3 biomarkers as predictors of AKI were 0.67 (0.51-0.83), 0.68 (0.55-0.81), and 0.78 (0.65-0.91), respectively. When they were categorically classified as elevated/normal, each additional elevated biomarker increased the odds for AKI (OR, 2.83; 95% CI, 1.23-6.52, P = .01). Agreement between sCr and sSDMA was poor (Cohen's kappa = .071). The AUROC of SDMA at presentation for AKI prediction was 0.73 (0.51-0.95). CONCLUSIONS AND CLINICAL IMPORTANCE: Kidney injury was common, irrespective of subsequent worsening of azotemia or death. The predictive value of individual urinary biomarkers was reduced by moderate sensitivities and specificities. SDMA showed moderate discriminatory utility for AKI prediction, and often displayed discordant results with sCr.

Validation of two behaviour-based pain scales for horses with acute colic.

Two behaviour-based scales for evaluating abdominal pain in horses (Equine Acute Abdominal Pain Scales, EAAPS-1 and -2) and a numerical rating scale (NRS) were compared for reliability and validity. Forty-one equine veterinarians randomly assigned into three groups were each presented a different set of 28 moving picture films randomly chosen among 36 films of horses with colic and four controls. One randomly chosen film was embedded twice within each set. The first (n=15) and the second (n=16) groups scored pain with the EAAPS-1 and EAPPS-2, respectively, while the third (n=10) used the NRS. The intra-class correlations (ICC) for EAAPS-1 (0.80) and EAAPS-2 (0.76) vs. NRS (0.67) indicated superior inter-rater reliability for both EAPPS scales. The intra-rater reliability of the EAAPS-1 was superior to both the other scales (weighted κ=0.9) vs. 0.5 and 0.7 for EAAPS-2 and NRS, respectively). The convergent validity between both EAAPS scores and the NRS scores was substantial (weighted κ=0.64). Both EAAPS scales discriminated well between extreme groups (areas under the receiver operating characteristic curve, ROC, area under the curve, AUC, >0.9) to differentiate severe from mild pain, as judged by the NRS. Both EAAPS scales showed predictive validity comparable to NRS (AUCs for dichotomous treatment modality (none and medically treated vs. surgically treated or euthanased) and with mortality (dead vs. alive) between 0.6 and 0.7 for all three scales. EAAPS-1 was the most reliable of the three scales and both EAAPS scales demonstrated validity comparable to the NRS scale.

A behaviour-based pain scale for horses with acute colic: scale construction.

A validated tool for assessing the severity of acute abdominal pain is needed for the effective management of colic in horses. Two behaviour-based colic pain scales were constructed by combining together mathematical and judgemental approaches. The mathematical approach identified easily-recognised pain behaviours to select as items. The judgemental approach further modified the items and weighted them based on expert-opinion. Thirty equine practitioners assessed the level of pain demonstrated in 23 film clips of clinical cases exhibiting signs of acute abdominal pain prospectively using a 10cm visual analogue scale (VAS). The practitioners also identified behaviours noted in each clip from a checklist of 23 behaviours identified from the literature. Nine behaviours had insignificant bias and moderate-to-excellent inter-observer agreement (multirater kappas: 0.5-0.95). Six experienced veterinarians then completed questionnaires in an iterative Delphi process to independently judge 15 items that best reflected severity of pain out of 42 items generated from the literature. Two behaviours were generated by the process. Subsequently, an advisory panel of three equine practitioners constructed two clinimetric-type scales based on the results of both approaches. The two resulting equine acute abdominal pain scales (EAAPS) included 12 behaviours. One weight was assigned to each behaviour in the EAAPS-1. In the EAAPS-2, gradations of weights were assigned, based on the frequency of the behaviour being demonstrated. The EAAPS scales are the first pain severity scales designed specifically for clinical use in cases of acute colic utilising the clinimetric approach to scale construction. Further studies are underway to validate the scales.
