RESUMO
Objective: The objective of this study was to assess dog owners' concern regarding peri-operative nausea and vomiting, and their willingness to pay for treatment. Design: Descriptive survey. Sample: A survey was administered to 104 dog owning clients with non-emergent surgical (52) or non-surgical (52) appointments at a University teaching hospital. Procedure: Descriptive statistics were calculated. A Mann-Whitney U test was used to detect differences between clients expecting their pet to undergo elective general anesthesia and those that did not. A Spearman's Rank Co-efficient was used to correlate predictive data. Results: Ninety-seven (93%) dog owners had at least some worry regarding their dog experiencing nausea associated with opioid analgesics and anesthesia, with 39/104 (37.5%) moderately to very worried. Forty-one owners (39%) would definitely and 59/104 (56.7%) would likely choose treatment to decrease or prevent signs of nausea. Ninety-four owners (90.4%) had at least some worry regarding vomiting, and 48/104 (46%) indicated they were moderately to very worried. Fifty-three owners (51.4%) would definitely and 49/103 (47.6%) would likely choose treatment to prevent vomiting. The median and mean amount owners were willing to pay was 50 and 76.47 USD, respectively. Ninety-five (91.3%) were likely or very likely to opt for treatment if required to arrive 1 h earlier for their appointment. There was no correlation between age, income, or owner's PONV experience with likelihood of choosing treatment but there was a significant positive correlation with the owner's level of education. Conclusion: Canine owners are concerned with their pets experiencing nausea and vomiting in relation to opioid analgesics and anesthesia and are willing to pay and stay the required time for effective treatment.
RESUMO
Certain avian tendons are known to mineralize normally in a gender-related manner. These tendons have unique properties, as well as several features common to calcifying cartilage and bone in other vertebrate species. In cartilage and bone, mineralization has been associated with a vascular and microvascular origin, but such a relationship has not been established in the avian tendon. Here the vasculature and mineral deposition in the calcifying leg tendon of the turkey have been documented for the first time utilizing a combination of histology, immunochemistry, radiology, and novel three-dimensional image reconstruction methods based on computed tomography. The data describe the blood supply to turkey leg tendon and show that the vascularity of this tissue is correlated with the onset of mineralization: At local levels of structural hierarchy, a vascular bed precedes mineral formation and the sites of vascular invasion correspond spatially with those of mineral deposition. Relatively unvascularized tendon regions remain uncalcified. These results support the concept that vascularization and mineralization are functionally related in the tendon, and they suggest that vascular invasion provides a mechanism underlying subsequent mineral deposition in this tissue.
