Factors influencing the incidence and prognosis of canine mammary tumours

JOURNAL OF SMALL ANIMAL PRACTICE, Issue 7 2000
M. D. Perez Alenza
Factors relating to the incidence of canine mammary tumours are reviewed. Increased age, intact status or ovariectomy after 2.5 years of age, as well as progestagen treatment, can all lead to an increased risk of mammary neoplasia in the bitch. In addition, obesity early in life, and a habitual diet based on home-made food (rich in beef and pork, and poor in chicken) as opposed to commercial food, are also associated with the occurrence of mammary tumours. Other aspects related to incidence are also discussed. Increased age at diagnosis, invasive growth (fixed to adjacent tissues), large tumour size, ulceration of skin, and axillary or inguinal node involvement are clinical parameters associated with a low chance of survival after surgical excision of mammary tumours. Histological typing and grading of the tumour allows the establishment of a prognosis, which is poor where there is tumour proliferation as measured by S-phase fraction determination and Ki-67 immunostaining.

Feeding Practices of Dog and Cat Owners Reflect Attitudes Toward Pet Foods

JOURNAL OF ANIMAL PHYSIOLOGY AND NUTRITION, Issue 11-12 2005
K. N. Willoughby
The PET DINER study was a telephone survey conducted to better understand why pet owners make certain nutritional decisions for their pets. Both dog and cat owners were included, which allowed us to differentiate the way people feed pet cats vs. pet dogs and how that might reflect owners' attitudes about pet foods. Prospective survey respondents were selected from local telephone books using a randomized process. A total of 18,194 calls were made from the five study sites between May and August, 2004. 1074 people (6%) representing 619 dogs and 455 cats completed the survey. Detailed information about feeding practices was collected. Pet owners' perceptions were assessed based on agreement/disagreement with statements regarding pet foods and the pet food industry. The Mann,Whitney Rank Sum test was used to detect differences between dog and cat owners and the Kruskal,Wallis one-way analysis of variance on ranks was used to evaluate differences among pet owners based on both type of pet and feeding practices (,75% commercial vs. ,50% home-prepared diets). More cats than dogs ate commercial pet food as ,75% of their main diet (96% vs. 87%, respectively; p < 0.001), and more dogs than cats ate a home-prepared food as ,50% of their main diet (6% vs. 3%, respectively; p < 0.009). For five of the statements, a difference in the attitudes of cat vs. dog owners was detected (p < 0.05). In general, this reflected more positive attitudes regarding commercial foods and less positive attitudes regarding home-prepared foods on the part of cat vs. dog owners. Analysis based on both type of pet and feeding practices identified significant differences among groups for 18/26 statements. However, when the Dunn's Method for pairwise multiple comparisons was applied, significant differences were due to feeding practices rather than type of pet for 17/18 statements. Only differences in attitudes about the statement ,raw bones can be safely fed to pets' remained significant for cat vs. dog owners feeding commercial foods. In conclusion, more cat owners than dog owners feed ,75% commercial foods to their pets and this is reflected in different attitudes about the nutritional soundness of commercial pet foods. [source]

Acrylamide: An Update on Current Knowledge in Analysis, Levels in Food, Mechanisms of Formation, and Potential Strategies of Control

NUTRITION REVIEWS, Issue 12 2004
Richard H. Stadler PhD
This review summarizes the research to date on acrylamide levels in food, analytical methods, main sources of dietary exposure, mechanisms of formation, and mitigation research in the major food categories. Significant progress in the research has been made over the past 18 months, as reflected by the numerous publications and national and international workshops on the subject. This rapid pace of developments is mainly attributable to the coordinated and collaborative efforts of all of those concerned: the food industry, academia, private/enforcement laboratories, and national authorities. Most of the information gaps identified since the findings in early 2002 on the occurrence of acrylamide in foods and exposure assessments have been addressed, and public databases have been established by several authorities. Today, the performance of analytical methods, particularly for "difficult" food matrices, is adequate, and any modifications made over the past 12 to 18 months in analytical procedures did not significantly impact the initial exposure calculations. Several avenues into mitigation have been explored in the different food categories, with much emphasis being placed on potato-based products, and empirical trials (mostly pilot studies) have provided better knowledge of the key parameters that influence acrylamide formation. However, despite these intensive efforts, only marginal reductions have been achieved by the food industry, and any further progress will entail long-term studies at the primary production level. Any measures devised to reduce exposure to acrylamide in commercial foods must be carefully assessed in terms of food safety and quality. A hitherto poorly addressed concern is the formation of acrylamide in foods prepared by consumers in the home, and more guidance on this by national authorities is warranted. [source]
