Background
Population characteristics and outcome of cats with arterial thromboembolism (ATE) managed in general practice (GP) have been poorly described.Hypothesis
Cats with ATE presenting to GP are usually euthanized at presentation, but survival times >1 year are possible.Animals
Cats with ATE managed by 3 GP clinics in the United Kingdom.Methods
Records of cases presenting to GP over a 98‐month period (2004–2012) were reviewed. Cats with an antemortem diagnosis of limb ATE were included. Outcome information was obtained.Results
Over 98 months, 250 cats were identified with ATE. Prevalence was approximately 0.3%. At presentation, 153 cats (61.2%) were euthanized, with 68/97 (70.1%) of the remaining cats (27.2% of the total population) surviving >24 hours after presentation. Of these, 30/68 (44.1%) survived for at least 7 days. Hypothermia (HR, 1.44; 95% CI, 1.002–2.07; P = .049) and management by Clinic 2 (HR, 5.53; 95% CI, 1.23–24.8; P = .026) were independent predictors of 24‐hour euthanasia or death. For cats surviving >24 hours, hypothermia (HR, 2.25; 95% CI, 1.12–4.48; P = .021) and failure to receive aspirin, clopidogrel, or both (HR, 8.26; 95% CI, 1.39–50; P = .001) were independent predictors of euthanasia or death within 7 days. For cats that survived ≥7 days, median survival time was 94 (95% CI, 42–164) days, with 6 cats alive 1 year after presentation.Conclusions
Although 153/250 cats were euthanized at presentation, 6 cats survived >12 months. No factors were identified that predicted euthanasia on presentation. 相似文献The spawning season of S. niloticus appears to attain a discrete peak in April–May, whilst the spawning season of S. aureus extends from May to September with at least two actual spawnings within this period. Natural spawning cycles are compared with those observed in fish ponds.
A more extended spawning period of S. aureus may explain the reduced growth rate of the species after the first year. The spawning cycle of all species coincides with the temperature regime of the water bodies. The fecundities of S. aureus and S. niloticus are similar and are described by log F = log 1.33 + 2.23 log L, which suggests that small fishes produce more eggs per g body weight than large.
The salinity tolerance of the Nile tilapia can be ranked as T. zillii > S. galilaeus > S. aureus > S. niloticus. Evidence on chronic and acute effects of salinity are reviewed and upper estimates for salinities giving unimpeded growth are deduced as being, T. zillii 29‰, S. galilaeus 15–20‰, S. areus 10–15‰ and S. niloticus 5–10‰. 相似文献
