The probability of CKD diagnosis in cats was influenced by several variables; recent weight loss, particularly in combination with the other factors, warrants assessment of cats for CKD.

Canine juvenile-onset generalized demodicosis (JOGD) is a common skin disorder suspected to be associated with multiple risk factors, including breed predispositions. These risk factors have not been well documented in a large population. A retrospective case-control study was conducted by searching the electronic medical records of 1,189,906 dogs examined at 600 hospitals during 2006 in order to assess the risk factors associated with JOGD in the USA. Multivariate analyses were conducted using logistic regression to estimate the relative risk with the odds ratio for variables hypothesized to influence the risk for canine demodicosis. Breeds (odds ratio) found to have the greatest association with a diagnosis of JOGD were American Staffordshire terrier (35.6), Staffordshire bull terrier (17.1) and Chinese shar-pei (7.2). Nonbreed risk factors (odds ratio) significantly associated with a diagnosis of JOGD were the diagnosis of pyoderma (5.5), coccidiosis (2.7) or hookworms (1.5), short coat (1.9) and nonenrollment in a preventative care wellness plan (1.5). Documenting these risk factors may help veterinarians to prioritize differential diagnoses and will aid in the design of prospective studies to elucidate the pathogenesis of demodicosis in dogs.

Many young adult (1- to < 4-year-old) dogs (32%) were uncastrated, signaling a need to promote earlier castration. Outreach efforts should be directed toward owners of pets least likely to be castrated, such as male dogs, dogs of specific breeds (ie, pit bull-type and Chihuahua), and dogs in the Southeastern United States. Additional research is needed to evaluate the potential impact of wellness programs on an owner's decision to have his or her pet castrated.

OBJECTIVE To identify risk factors for anesthetic-related death in pet dogs and cats. DESIGN Matched case-control study. ANIMALS 237 dogs and 181 cats. PROCEDURES Electronic medical records from 822 hospitals were examined to identify dogs and cats that underwent general anesthesia (including sedation) or sedation alone and had death attributable to the anesthetic episode ≤ 7 days later (case animals; 115 dogs and 89 cats) or survived > 7 days afterward (control animals [matched by species and hospital]; 122 dogs and 92 cats). Information on patient characteristics and data related to the anesthesia session were extracted. Conditional multivariable logistic regression was performed to identify factors associated with anesthetic-related death for each species. RESULTS The anesthetic-related death rate was higher for cats (11/10,000 anesthetic episodes [0.11%]) than for dogs (5/10,000 anesthetic episodes [0.05%]). Increasing age was associated with increased odds of death for both species, as was undergoing nonelective (vs elective) procedures. Odds of death for dogs were significantly greater when preanesthetic physical examination results were not recorded (vs recorded) or when preanesthetic Hct was outside (vs within) the reference range. Odds of death for cats were greater when intra-anesthesia records for oxygen saturation as measured by pulse oximetry were absent. Underweight dogs had almost 15 times the odds of death as nonunderweight dogs; for cats, odds of death increased with increasing body weight (but not with overweight body condition). CONCLUSIONS AND CLINICAL RELEVANCE Several factors were associated with anesthetic-related death in cats and dogs. This information may be useful for development of strategies to reduce anesthetic-related risks when possible and for education of pet owners about anesthetic risks.
