Simple SummaryMicrochip identification has become an important tool to reunite stray dogs and cats with their owners, and is now compulsory in most states of Australia. Improvement of the microchipping system in Australia is limited by a lack of published Australian data documenting the problems experienced by shelter staff when using microchip data to contact the owner of a stray animal. In this study we determine the character and frequency of inaccurate microchip data to identify weaknesses in the current microchipping system. This information could be used to develop strategies that increase the accuracy of microchip data that will increase the reclaiming of stray animals.AbstractA lack of published information documenting problems with the microchip data for the reclaiming of stray animals entering Australian shelters limits improvement of the current microchipping system. A retrospective study analysing admission data for stray, adult dogs (n = 7258) and cats (n = 6950) entering the Royal Society for the Prevention of Cruelty to Animals (RSPCA) Queensland between January 2012 and December 2013 was undertaken to determine the character and frequency of microchip data problems and their impact on outcome for the animal. Only 28% of dogs and 9% of cats were microchipped, and a substantial proportion (37%) had problems with their data, including being registered to a previous owner or organisation (47%), all phone numbers incorrect/disconnected (29%), and the microchip not registered (14%). A higher proportion of owners could be contacted when the microchip had no problems, compared to those with problems (dogs, 93% vs. 70%; cats, 75% vs. 41%). The proportion of animals reclaimed declined significantly between microchipped animals with no data problems, microchipped animals with data problems and non-microchipped animals—87%, 69%, and 37%, respectively, for dogs and 61%, 33%, and 5%, respectively, for cats. Strategies are needed to increase the accuracy of microchip data to facilitate the reclaiming of stray dogs and cats.

Hundreds of species in one of Australia's dominant plant families, the Myrtaceae, are at risk from the invasive pathogenic fungus Austropuccinia psidii. Since its arrival in Australia in 2010, native plant communities have been severely affected, with highly susceptible species likely to become extinct from recurring infections. While severe impact on Australian native and plantation forestry has been predicted, the lemon myrtle industry is already under threat. Commercial cultivars of lemon myrtle (Backhousia citriodora) are highly susceptible to A. psidii. Detecting and monitoring disease outbreaks is currently only possible by eye, which is costly and subject to human bias. This study aims at developing a proof‐of‐concept for automated, non‐biased classification of healthy (naïve), fungicide‐treated and diseased lemon myrtle trees by means of their spectral reflectance signatures. From a lemon myrtle plantation, spectral signatures of fungicide‐treated and untreated leaves were collected using a portable field spectrometer. A third class of spectra, from naïve lemon myrtle leaves that had not been exposed to A. psidii, was collected from a botanical garden. Reflectance spectra in their primary form and their first‐order derivatives were used to train a random forest classifier resulting in an overall accuracy of 78% (kappa = 0.68) for primary spectra and 95% (kappa = 0.92) for first‐order derivative‐transformed spectra. Thus, an optical sensor‐based discrimination, using spectral reflectance signatures of this as yet uninvestigated pathosystem, seems technically feasible. This study provides a foundation for the development of automated, sensor‐based detection and monitoring systems for myrtle rust.

Simple SummaryEuthanasia is used in developed countries as a method of population control for dogs and cats entering shelters and council pounds. This study analyzed all available dog and cat population, registration, intake and outcome data for the 79 Victorian councils. The majority (74%) of councils achieved euthanasia rates for dogs of ≤10%, but only one achieved that for cats, and mean cat euthanasia was 48%. Low euthanasia rates were associated with high rates of reclaim, and adoption of unclaimed animals. A telephone survey of 35 councils (44%) was undertaken to identify policies, practices and attitudes of staff to identify strategies that reduce euthanasia. It is envisaged this data could be used as a resource for councils to lower euthanasia rates.AbstractUsing euthanasia to manage dog and cat overpopulation causes health issues and emotional stress in employees involved, increases staff turnover, and has financial, moral and ethical ramifications for communities. Welfare agencies and local government agencies (councils) share responsibility for managing companion animal populations. This study investigated Australian councils in the state of Victoria, to identify strategies used to reduce euthanasia. Statistics regarding animal populations, registration, intake, reclaim, rehome and euthanasia were obtained from the Domestic Animal Management Plan of each council. Of the 79 Victorian councils, 74% achieved ≤10% euthanasia of impounded dogs, which is widely quoted as zero euthanasia of adoptable and treatable animals. The mean euthanasia rates for cats by the councils was 48%, with only one council achieving a euthanasia rate of ≤10% for cats. Mean reclaim rates for dogs were higher (73%) than for cats (13%), as was the mean proportion of unclaimed dogs rehomed (71%), compared to cats (45%). Telephone questionnaires were conducted with animal management officers from 35 councils (44%). Those with low euthanasia rates had high reclaim rates and/or rehome rates. Reclaim, rehome and euthanasia rates for dogs and cats were not significantly different between councils that operated their own pound facilities and those that utilized the services of welfare organizations to operate pounds on behalf of the council. More council managers believed they would never achieve ≤10% euthanasia for cats (49%) than for dogs (11%). A variety of strategies were used by councils to achieve high reclaim and rehoming rates.

Objectives A hostile proximal neck anatomy is the most common cause of abdominal aorta endovascular aneurysm repair failure leading to a higher risk of device migration, proximal type I endoleak, and subsequent open surgical repair. Endostapling is a technique to attain better fixation of the endograft to the aortic wall, and the only available device in the USA is Aptus Heli-FX EndoAnchor system (Medtronic Vascular, Santa Rosa, CA, USA). Preliminary data have shown efficacy and safety of its use, and the aim of this study is to assess device-related adverse events in real-world clinical use. Methods We quarried data from the publicly available Manufacturer and User Facility Device Experience database to identify Aptus Heli-FX EndoAnchor system-related adverse reports in endovascular aneurysm repair since FDA approval till August 31, 2017. An estimate of total devices implanted in the United States was quoted around 7,000 (Medtronic marketing internal data). Results Our query identified 229 separate reports, of which there were 85 adverse events (1.2% of the estimated EndoAnchor systems used). The most common adverse events were device dislodgement/fracture (65) and applicator malfunction (20). Conclusion In early post-FDA approval use in a real-world setting, the EndoAnchor system is associated with a low rate of adverse events. Device dislodgement and embolization remain the most common adverse events. With increasing use of these devices in more difficult anatomy, careful patient selection and careful attention to technique may help to reduce these events even further.
