Aquarium pets release is an important vector for invasive species establishment in freshwater ecosystems. Here the perceptions and risk behaviors associated to this vector were evaluated using a survey. Portuguese aquarium hobbyists were interviewed through an on-line survey (Google forms) publicized in 9 web sites connected to this hobby (Facebook pages and internet forums). A Pet Propagule Pressure index (PPP), congregating information regarding pet’s popularity and electivity for discharge, was developed and applied in this study, so that relative comparisons can be made among different pet types (taxa). Additionally, non-metric Multidimensional Scaling (nMDS) was applied to pet owner’s data to identify indicator factors associated with risk behaviors and impacts’ awareness. Results indicated that aquarium pet owners usually only have one pet type, most commonly fish or turtles. Only 8% of the owners admit having discharged pets, being more commonly reported the release of only one pet. This risk behavior is connected mainly to the excessive growth of the pet and consequently lack of space in the aquariums. Pet’s discharge occurs until 100 km of distance from owner’s homes, being very common at distances lower than 1 km. The PPP index developed in this study, indicates the pet types with higher risk of discharge were the turtles and the fishes. Pet owner’s awareness regarding the pet discharges impacts in the environment seems to be lower than other risk groups connected to biological invasions in freshwaters, namely anglers. Pet owners most aware of these impacts were associated to higher education levels and higher experience on this hobby. Our study highlights the needs for more environmental education on particular social groups within aquarium pets’ owners, namely those that have started this activity or have lower education levels, to decrease the biological invasion risks associated to this hobby. Additionally, our findings regarding the patterns and drivers of discharge action itself are useful to model risk invasion, as well as for detection, management and control of these species.

Elizabeth Haines1, Robert van Amerongen2, Robert Birkhahn1, Wendy Wen1, Theodore Gaeta11Department of Emergency Medicine, 2Pediatric Emergency Services, New York Methodist Hospital, Brooklyn, NY, USAAbstract: Acute gastroenteritis accounts for 1–2 million annual pediatric emergency department visits in the US. The current literature supports the use of antiemetics, such as ondansetron, in the emergency department, reporting improved oral rehydration, cessation of vomiting, and reduction in the need for intravenous rehydration. However, there remains concern that using these agents may “mask alternative diagnoses” and negatively impact patient care. We present a case series of 29 patients who received a pediatric emergency department discharge action plan which allowed for a dose of ondansetron to be dispensed by the clinician at the time of discharge. Patients were instructed to administer the ondansetron at home for treatment of ongoing nausea and vomiting any time after 6 hours from the time of emergency department discharge. These patients were followed up at 3–5 days following discharge to assess for outcomes. Implications of this discharge action plan and future directions are discussed.Keywords: gastroenteritis, ondansetron, discharge action plan
