Prospective, randomized surgical trials with pre-defined objective measures would be required to further evaluate the clinical importance of these preliminary findings which suggest that TPLO may help stabilize the cranial tibial thrust as originally proposed.
Path analysis and multiple logistic regression with an extrabinomial variation error term (to account for herd) were used to model seven postpartum clinical disorders of dairy cows and factors related to the calf. Data were from 7761 lactation records from 34 commercial herds in the vicinity of Cornell University. Stillbirth increased the odds of developing metritis and retained placenta. The odds of developing dystocia and mastitis were lower when the sex of the calf was female. However, cows that twinned had increased odds of developing dystocia and retained placenta. Dystocia was related to an increase in the odds of retained placenta. Milk fever, dystocia, and ketosis each increased the odds of developing left-displaced abomasum. Postpartum periods with dystocia, retained placenta, or ketosis had increased odds of metritis. Two interaction terms involved parity: stillbirth for milk fever and retained placenta for ketosis. The extrabinomial variation error term contributed to the fit in all models.
In dogs with osteosarcoma treated with limb-salvage surgery, infection has a positive influence on survival, as does a smaller initial length of radius involved and lower body weight.
Results document an expansion of the known geographic range for babesiosis among dogs in the United States. Testing for babesiosis should be pursued in dogs with clinicopathologic abnormalities consistent with immune-mediated hemolytic anemia or thrombocytopenia, particularly if there is a history of a recent dog bite.
On the basis of sensitivity and specificity, basal serum or plasma cortisol concentrations had high negative predictive values over a wide range of prevalence rates and can be used to rule out a diagnosis of hypoadrenocorticism. Dogs with basal cortisol concentrations > 2 microg/dL that are not receiving corticosteroids, mitotane, or ketoconazole are highly unlikely to have hypoadrenocorticism. However, if the basal cortisol concentration is
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
