Evaluation of different methods of environmental enrichment to control anxiety in dogs undergoing hemilaminectomy after acute intervertebral disc extrusion: a randomized double-blinded study.

The goal of this randomized, double-blinded, placebo-controlled study was to evaluate the effect of environmental enrichment (EE) on post-operative pain and anxiety in dogs following hemilaminectomy for acute intervertebral disc extrusion (IVDE). Twenty healthy client-owned dogs undergoing a hemilaminectomy for IVDE with the same immediate post-operative analgesia protocol were randomly assigned to either the EE or standard environment (SE) group post-operatively. Recovery was achieved in an intensive care room (SE) or a separate quiet room (EE) equipped with white noise and classical music. EE dogs were also exposed to dog-appeasing pheromones, essential oil scents, and positive human interactions and were provided meals through food toys. A blinded evaluator assessed all dogs using the modified Glasgow Composite Pain Scale (mGCPS) on presentation and at several time points post-operatively. A rescue injection of the opioid methadone was given to the dogs with an mGCPS score of ≥5/20. Dogs received the antidepressant trazodone when anxious behaviors (5 mg/kg) were observed. The mGCPS scores, the latencies to receive the first methadone and trazodone doses and to eat the first meal, the number of methadone and trazodone doses, and the number of meals ingested in the first 24 and 48 h post-surgery were compared using Wilcoxon tests, and Benjamini-Hochberg correction for false discovery rate was applied. Although median mGCPS scores did not differ between the groups, compared to SE dogs (n = 10), EE dogs (n = 6) received trazodone earlier (p = 0.019), were administered fewer methadone injections at 24 h (p = 0.043), and ate more at 48 h post-surgery (p = 0.007). Therefore, EE and anti-anxiety medications could be beneficial in improving the wellbeing of dogs post-operatively.

Lead and other toxic metals in plastic play foods: Results from testing citizen science, lead detection tools in childcare settings

A method development pilot study examining citizen science tools for assessing lead in childcare settings identified plastic food toys as an unexpected potential source of lead and arsenic. Collaborating researchers at three universities sought to develop a low cost, replicable approach for use in childcare centers to identify lead. Through graduate Environmental Health courses at Northeastern and Boston Universities, 197 Plastic Food Toys (PFTs) used in a childcare center were tested for lead using a portable X-Ray fluorescence (XRF) instrument and a colorimetric wipe method for detecting surface lead. The XRF identified concerning levels of lead and co-occurring arsenic in PFTs. The XRF analysis found 8.63% (17/197) of PFTs from the childcare center contained more than 100.00 ppm of lead, the U.S. Consumer Protection Safety Commission's (CPSC) upper regulatory threshold for lead in childrens' products. However, wipes did not detect removable surface lead. Lead concentrations ranged from 6.14 ppm to 11,999.00 ppm with a median of 40.00 ppm. Additionally, 7.10% of all PFTs tested had detectable levels of arsenic which ranged from 9.30 ppm to 1134.42 ppm and had a median value of 113.20 ppm. Arsenic concentrations in 6.60% of PFTs' exceeded the US voluntary standard for arsenic in children's products of 25.00 ppm (adopted from the EU standard). These findings prompted further sampling of similar newly-purchased PFTs. None of the newly-purchased PFTs tested positive for lead or arsenic (0/87). Several other elements were also identified, particularly in the used PFTs. Because these food-like toys are frequently put in children's mouths, we recommend further investigation of PFTs in circulation via citizen science combining the wipe and XRF method as they provide immediate data to participants. Additionally, CPSC should consider a systematic recall of some used PFTs to prevent exposure disparities by socio-economic status and increased surveillance for other toxic metals in new PFTs.

Effects of Environmental Enrichment on Dog Behaviour: Pilot Study.

Simple SummaryThe quality of life for domestic and captive animals can be enhanced and improved by providing additional stimuli and activities, known as environmental enrichment (EE). However, it is important to ensure the enrichment provides benefit to the animal, and as such the behaviour of the animals can be monitored to understand the activities’ impacts. A pilot study was undertaken to evaluate the impact of seven different EE activities on the behaviour of 10 training dogs housed in an office environment during training within an assistance dog charity. Results suggest there is a need to diversify thinking around EE, shifting common thinking of EE as one entity to instead consider EE in different categories and to ensure animals receive a mixture of EE types.Environmental enrichment (EE) can be used to enhance the environment of various animals. The aim of this pilot study was to determine the effects of seven EE activities (Bonding, Bubble machine, Conspecific play, Interactive toy, Playhouse, Stuffed food toy and Tug play) on dog behaviour, pre- and post-EE for dogs housed in an office environment during training as part of an assistance dog training programme. EE activities resulted in a significant increase in the frequency of relaxation behaviours (p < 0.01) and a significant reduction in alert (p < 0.01) and stress behaviours (p = 0.02). Results suggest various benefits of the different activities with Conspecific Play and Playhouse activities having the greatest overall positive behaviour change when compared to the other activities. The food-based EE activities (Interactive toy and Stuffed food toy) had the least behaviour change of all the activities provided. Findings will be of interest to pet owners, animal rescue centres, dog trainers and working dog organisations.

Effect of food toys on owner-perceived quality of life of cats during a prescribed weight loss plan.

To determine the effect of a food toy on owner-perceived quality of life (QOL) of overweight cats during a weight loss plan. 44 adult cats, 1 to 10 years of age with a body condition score (BCS) ≥ 7/9. Cats were randomly assigned to the food toy or food bowl group. Cat owners completed an initial questionnaire and received a prescribed weight loss plan, bag of dry veterinary therapeutic cat food formulated for weight loss, measuring cup, and food bowl or ball-type food toy. Body weight and BCS were checked monthly. Owners completed a monthly questionnaire to assess their cat's QOL. Low-calorie vegetables were offered to 32 cats whose owners reported disruptive food-seeking behavior. Of the 44 cats in the final analysis, 29 cats either lost ≥ 2 BCS points or achieved an ideal BCS. Owner-perceived QOL was higher at the final weigh-in, compared with that at the initial weigh-in. An effect of food toy versus food bowl on owner-perceived QOL was not detected. Of the cats offered vegetables, 28 cats would eat the vegetables with a palatability additive; 4 cats ate vegetables plain. Owner-perceived QOL was higher at the end of the study. Feeding overweight cats by use of a ball-type food toy did not influence owner-perceived QOL. Low-calorie vegetables can successfully be added to the weight loss diet to promote satiety; albeit, a palatability additive is likely needed. Further studies regarding feeding management for cats during a weight loss plan should be explored.

Pilot study evaluating the effect of feeding method on overall activity of neutered indoor pet cats

Abstract Indoor housing of cats is associated with a higher incidence of multiple diseases, including obesity. Increased exercise is often recommended as a method of creating or increasing the negative energy balance required for weight loss. Food-dispensing toys have been suggested as a method of increasing cat activity and providing environmental enrichment but have not been systematically evaluated in client-owned cats. To compare the effect of meal feeding from a bowl versus a food-dispensing toy on overall activity, 19 client-owned cats were enrolled in a 2-way, 2-period, and randomized repeated-measures mixed-effects crossover study. All cats were acclimated to wearing an accelerometer attached to a collar during week 1. Cats randomized to the bowl-first condition were acclimated to bowl feeding during week 2, and activity counts were collected during week 3. Cats randomized to the toy-first condition were acclimated to toy feeding during week 2, and activity counts were collected during week 3. During week 4, feeding methods were crossed. Cats randomized to the bowl-first condition were acclimated to toy feeding during week 4, and activity counts were collected during week 5. Cats randomized to the toy-first condition were acclimated to bowl feeding during week 4, and activity counts were collected during week 5. The outcome measure of interest was the change in total activity during weeks 3 and 5 for both groups. No significant difference was found in average weekly ( P = 0.30) or daily activity counts ( P = 0.17) when cats were fed from a toy compared with a bowl. A treatment effect by day was observed with activity decreasing in the toy-first group and increasing in the bowl-first group between days 3 and 4 ( P = 0.028). In addition, we found that overall activity of cats decreased 6%-7% with each 1-year increase in age ( P = 0.041). Although the type of feeding method in this pilot study did not affect overall activity, providing meals to cats using food toys may provide other benefits related to satiety, stress reduction, and overall well-being. More research is needed to explore the benefits of alternative feeding practices for indoor cats.

A toy story: Association between young children's knowledge of fast food toy premiums and their fast food consumption

Fast food restaurants spend millions of dollars annually on child-targeted marketing, a substantial portion of which is allocated to toy premiums for kids' meals. The objectives of this study were to describe fast food toy premiums, and examine whether young children's knowledge of fast food toy premiums was associated with their fast food consumption. Parents of 3- to 5-year old children were recruited from pediatric and WIC clinics in Southern New Hampshire, and completed a cross-sectional survey between April 2013–March 2014. Parents reported whether their children usually knew what toys were being offered at fast food restaurants, and whether children had eaten at any of four restaurants that offer toy premiums with kids' meals (McDonald's, Burger King, Subway, Wendy's) during the 7 days preceding the survey. Seventy-one percent of eligible parents participated (N = 583); 48.4% did not receive any education beyond high school, and 27.1% of children were non-white. Half (49.7%) the children had eaten at one or more of the four fast food restaurants in the past week; one-third (33.9%) had eaten at McDonald's. The four restaurants released 49 unique toy premiums during the survey period; McDonald's released half of these. Even after controlling for parent fast food consumption and sociodemographics, children were 1.38 (95% CI = 1.04, 1.82) times more likely to have consumed McDonald's if they usually knew what toys were offered by fast food restaurants. We did not detect a relationship between children's toy knowledge and their intake of fast food from the other restaurants. In this community-based sample, young children's knowledge of fast food toys was associated with a greater frequency of eating at McDonald's, providing evidence in support of regulating child-directed marketing of unhealthy foods using toys.

Determination of organotin compounds in polyvinyl chloride toys

Organotin compounds in polyvinyl chloride toys were determined by GC/MS after ethyl derivatization with sodium tetraethylborate. The samples were 12 balls, 12 soft toys, 10 food toys and 13 face masks for children. Monooctyltin, dioctyltin and trioctyltin compounds were found in all face masks at the levels of 74.8-917 micrograms/g. 474-3,960 micrograms/g and 1.0-213 micrograms/g, respectively. They also were detected in 6 balls, 4 soft toys and 1 food toy. Monomethyltin and dimethyltin compounds were found in 8 face masks at the levels of 40.9-227 micrograms/g and 222-1,450 micrograms/g, respectively. Monobutyltin and dibutyltin (DBT) compounds were found in 1 ball, 3 food toys and 5 face masks. In particular, 1 ball and 4 face masks contained toxic DBT at the levels of 527-999 micrograms/g.
