ABSTRACT
BACKGROUND: Legislation pertaining to canine ownership in Ireland maintains a one-health perspective by establishing a minimum standard of care for dogs while safeguarding human health and wellbeing. However, public awareness of this legislation has not been measured. The goals of this study were first, to estimate and compare the level of awareness, among dog owners and non-dog owners, that eight responsibilities of dog owners are prescribed by law in Ireland. Second, to determine if gender modifies differences in awareness between owners and non-owners, and third to determine whether gender itself is independently associated with awareness of the legal specification of these dog ownership responsibilities. RESULTS: We conducted a cross-sectional study of 679 University College Dublin employees. Exposure information included participants' dog ownership status, gender, age, and education level. Among dog owners and non-dog owners, we estimated and compared the prevalences of persons with self-reported awareness that each of eight dog ownership responsibilities are prescribed by law in Ireland: Dog fouling in a public place, the leashing and muzzling of certain breeds, holding a dog license, straying of dogs, safeguarding health and welfare of dogs, dog abandonment, prohibition on tail docking of puppies and the mandatory wearing of identification. The prevalence of awareness was low among both dog owners and non-dog owners with substantial awareness (≥ 80%) of only three responsibilities: Those pertaining to fouling, licensing and muzzling and leashing. Awareness that more than one responsibility was specified by law was also poor with only 17.9% (95% CI: 15.1-20.9%) of participants aware of all eight and dog owners essentially just as likely (54%; 95% CI: 49-58%) to be aware of more than one as non-dog owners. For most dog ownership responsibilities, differences in prevalence (PD) of awareness between owners and non-owners and females and males were trivial (PD < 10%). Similarly for most responsibilities, gender did not modify awareness PDs between owners and non-owners. CONCLUSIONS: In this well-educated university community, self-reported awareness that these eight responsibilities of dog owners are prescribed by law in Ireland is poor with essentially no difference between dog owners and non-dog owners or males and females. Awareness was higher for those responsibilities which, when not discharged, result in direct negative consequences to humans compared to those that result in direct negative consequences to dogs. It is likely that awareness of the legal status of these eight responsibilities of dog owners among the general public in Ireland is even less than observed in this study.
ABSTRACT
The journey of life, from primordial protoplasm to a complex vertebrate form, is a tale of survival against incessant alterations in climate, surface topography, food chain, and chemistry of the external environment. Kidneys present with an ensemble embodiment of the adaptations devised by diverse life-forms to cope with such challenges and maintain a chemical equilibrium of water and solutes, both in and outside the body. This minireview revisits renal evolution utilizing the classic: From Fish to Philosopher; the story of our internal environment, by Prof. Homer W. Smith (1895-1962) as a template. Prof. Smith's views exemplified the invention of glomeruli, or its abolishment, as a mechanism to filter water. Moreover, with the need to preserve water, as in reptiles, the loop of Henle was introduced to concentrate urine. When compared to smaller mammals, the larger ones, albeit having loops of Henle of similar lengths, demonstrated a distinct packing of the nephrons in kidneys. Moreover, the renal portal system degenerated in mammals, while still present in other vertebrates. This account will present with a critique of the current concepts of renal evolution while examining how various other factors, including the ones that we know more about now, such as genetic factors, synchronize to achieve renal development. Finally, it will try to assess the validity of ideas laid by Prof. Smith with the knowledge that we possess now, and understand the complex architecture that evolution has imprinted on the kidneys during its struggle to survive over epochs.
