Assisting Decision-Making on Age of Neutering for 35 Breeds of Dogs: Associated Joint Disorders, Cancers, and Urinary Incontinence.

ABSTRACT: Neutering (including spaying) of male and female dogs in the first year after birth has become routine in the U.S. and much of Europe, but recent research reveals that for some dog breeds, neutering may be associated with increased risks of debilitating joint disorders and some cancers, complicating pet owners' decisions on neutering. The joint disorders include hip dysplasia, cranial cruciate ligament tear or rupture, and elbow dysplasia. The cancers include lymphoma, mast cell tumor, hemangiosarcoma, and osteosarcoma. In previous studies on the Golden Retriever, Labrador Retriever and German Shepherd Dog, neutering before a year of age was associated with increased risks of one or more joint disorders, 2-4 times that of intact dogs. The increase was particularly seen with dogs neutered by 6 months of age. In female Golden Retrievers, there was an increase in one or more of the cancers followed to about 2-4 times that of intact females with neutering at any age. The goal of the present study was to expand and use the same data collection and analyses to cover an additional 29 breeds, plus three varieties of Poodles. There were major breed differences in vulnerability to neutering, both with regard to joint disorders and cancers. In most cases, the caregiver can choose the age of neutering without increasing the risks of these joint disorders or cancers. Small-dog breeds seemed to have no increased risks of joint disorders associated with neutering, and in only two small breeds (Boston Terrier and Shih Tzu) was there a significant increase in cancers. To assist pet owners and veterinarians in deciding on the age of neutering a specific dog, guidelines that avoid increasing the risks of a dog acquiring these joint disorders or cancers are laid out for neutering ages on a breed-by-breed and sex basis.

Project description:The early neutering of male and female dogs and its relationship to an increased risk of joint disorders and some cancers has recently become a concern, raising questions about the standard practice in the U.S. and much of Europe of neutering by 6 months of age. A noteworthy recent finding from this center is that there are major breed differences with small-dog breeds generally showing little vulnerability to neutering compared with breeds of larger body size. These findings on purebreds raise questions for dog owners and veterinarians about mixed-breed dogs. The purpose of this study was to examine a sample of mixed breed dogs of five weight categories using the same veterinary hospital database and diagnostic criteria for joint disorders and cancers as used in the newly published paper on 35 breeds and previous papers on the Golden Retriever, Labrador Retriever, and German Shepherd Dog. The weight categories were <10 kg (739 cases), 10-19 kg (546 cases), 20-29 kg (992 cases), 30-39 kg (604 cases), and over 40 kg (258 cases). Males and females were analyzed separately, as were various ages at neutering. The joint disorders examined were hip dysplasia, cranial cruciate ligament tear or rupture, and elbow dysplasia. The cancers were lymphoma, mast cell tumor, hemangiosarcoma, and osteosarcoma. There was no significant increased occurrence of one or more cancers, compared with intact dogs, in any weight category. However, in the three categories of dogs weighing 20 kg or more, neutering before 1 year generally was significantly associated with risks of one or more joint disorders above that of dogs left intact, commonly to 3 times the level of intact dogs, with sex differences in the degrees of joint disorders associated with neutering. For the dogs in the two weight categories <20 kg, no increased risks were found for joint disorders. This information can be useful to dog caregivers in deciding on the age at which to neuter specific dogs, and for veterinarians offering guidance to pet owners.

Project description:BackgroundMale stress urinary incontinence (SUI) is a known complication following surgical intervention on the prostate, particularly following surgery for prostate cancer. Effective surgical treatments for SUI include artificial urinary sphincter (AUS) and male urethral sling. Prior data suggest that men may forego available treatment despite bothersome symptoms. The objective was to explore how men who underwent surgical correction for post-prostatectomy SUI navigated SUI treatment decisions.MethodsMixed method study was employed. Semi-structured interviews, participant surveys and objective clinical assessment of SUI were performed among a group of men living with incontinence after prostate cancer surgery who underwent surgery for SUI at the University of California in 2017.ResultsEleven men were interviewed after consultation for SUI and all had complete quantitative clinical data. Surgery for SUI included AUS (n=8) and sling (n=3). There was a decrease in pads per day from 3.2 to 0.9 and no major complications. Most patients found that the impact on activities and their treating urologist were of great importance. Sexual and relationships played a variable role with some participants ranking these as "great deal of influence" and others "little or no influence". Participants who underwent AUS were more likely to cite a higher importance on "being very dry" in choosing that surgery while sling patients had more variable ranking of important factors. Participants found a variety of inputs helpful in hearing information about SUI treatment options.ConclusionsAmong a group of 11 men who underwent surgical correction for post-prostatectomy SUI, there were identifiable themes on how men make decisions, evaluate quality of life (QoL) changes and approach treatment options. Men value more than being dry with measures of individual success that can include sexual and relationship health. Furthermore the role of the Urologist remains crucial as patients relied heavily on input and discussion with their Urologist to assist in treatment decisions. These findings can be used to inform future studies of the experience of men with SUI.
