Caregiver burden in the veterinary dermatology client: comparison to healthy controls and relationship to quality of life.

BACKGROUND: Skin disease in companion animals often requires long-term management which may contribute to caregiver burden in the dermatology client. HYPOTHESES/OBJECTIVES: We expected greater caregiver burden in dermatology clients relative to healthy control veterinary clients and that no difference would be present between healthy controls and dermatology clients reporting good skin disease control. Within the dermatology sample, we hypothesized that greater caregiver burden would correlate with client perception of the animal's severity of disease (ASD), animal skin disease quality of life (ASD-QoL), and client general quality of life (CG-QoL) and skin disease-related quality of life (CSD-QoL). PARTICIPANTS: Participants were 358 dog owners, including veterinary dermatology clients (n = 152) and healthy general veterinary control clients (n = 206). METHODS AND MATERIALS: Cross-sectional online assessments were completed for client caregiver burden (both samples) and CG-QoL, CSD-QoL, ASD-QoL and ASD (dermatology sample only). RESULTS: Caregiver burden was greater in dermatology clients overall relative to healthy controls (P < 0.001); it was comparable for those reporting good skin disease control (P > 0.05). Within the dermatology group, correlations between caregiver burden and CSD-QoL were high (r = 0.58; P < 0.001). CG-QoL was predicted by caregiver burden (P < 0.001) but not significantly by CSD-QoL (P > 0.05). CONCLUSIONS AND CLINICAL IMPORTANCE: In the presence of good skin disease control, caregiver burden in dermatology clients is as low as general veterinary clients with a healthy dog. Understanding client experiences of companion animal skin disease may be optimized by assessing caregiver burden.

The in vitro antibacterial activity of incomplete iron salt of polyacrylic acid against Pseudomonas aeruginosa, meticillin-resistant Staphylococcus pseudintermedius and meticillin-resistant S. aureus.

BACKGROUND: The incomplete iron salt of polyacrylic acid (IIS-PAA) has been used for its haemostatic, wound healing and antibacterial properties in human patients. IIS-PAA is a water-soluble, acidic, hydrophilic polymer that is active at pH 2.9-4.0. HYPOTHESES/OBJECTIVES: To evaluate the antibacterial effect of IIS-PAA against Pseudomonas aeruginosa, meticillin-resistant Staphylococcus pseudintermedius (MRSP) and meticillin-resistant S. aureus (MRSA). METHODS: This was a prospective, nonblinded in vitro study. Sixty canine isolates of P. aeruginosa, MRSP and MRSA were included. Minimum inhibitory concentrations (MICs) of IIS-PAA were determined by agar dilution on Mueller-Hinton agar using testing concentrations ranging from 0.0625-0.4% (raw material 100%) and based on Clinical and Laboratory Standards Institute guidelines. RESULTS: The median MIC for P. aeruginosa was 0.2% (range 0.2-0.3%), mean 0.2% and standard deviation (SD) of 0.018%. The median MIC for MRSP was 0.05% (0.025-0.1%), mean 0.058% and SD 0.022%, and the median MIC for MRSA was 0.1% (0.00625-0.4%), mean 0.126% and SD 0.080%. There were significant differences in MICs between the three bacteria types with MICs highest for Pseudomonas and lowest for MRSP (all P < 0.0001). CONCLUSIONS: IIS-PAA had in vitro antibacterial activity against three important bacterial pathogens. Further studies of IIS-PAA are indicated to assess the potential clinical benefit and in vitro studies to investigate the spectrum of anti-bacterial activity and mode of action.
