A Survey of Pennsylvania Horse Management: Part Two - Exercise.

Understanding the frequency, duration, and intensity of exercise is important for determining the optimal diet and management of horses. The objective of the study was to characterize the exercise management of horses in Pennsylvania. An online survey was distributed from February 27th to August 31st, 2020. Respondents were asked to place their horse in an exercise category, as well as report on frequency and duration of exercise and time spent at each gait. Nonparametric statistics (mdn=median) and tests were used when data were not normally distributed. Of the 470 horses, 68% were regularly exercised. The exercised horses were classified as 49% (135/275) in light, 41% (113/275) in moderate, and 12% (32/275) in heavy/very heavy exercise. Of those exercised, 43% (120/278) were ridden recreationally (not used for competition). The median minutes per week spent exercising was 180 minutes (IQR=183). The average number of exercise sessions per week was 3.6 ± 2.2. Horses in heavy/very heavy (mdn=220 min, IQR=272) and moderate exercise (mdn=180 min, IQR=180) spent more minutes exercising per week compared to light exercise (mdn=120 minute, IQR=180; P< .05). Total number of exercise sessions completed per week differed between horses in light (mdn=2 sessions, IQR=3), moderate (mdn=4 sessions, IQR=2), and heavy/very heavy exercise (mdn=6 sessions, IQR=2; P < .05). Horses were exercised for a similar duration and frequency per week compared to previous studies. Some challenges exist for placing horses in NRC exercise categories based on self-reports only.

A Survey of Pennsylvania Horse Management: Part One-Nutrition.

Various aspects of nutritional management can impact both a horse's gastrointestinal (GI) health and caretaker costs. The objective of this study was to characterize the feeding management and GI issues of horses in Pennsylvania (PA). An online survey was distributed from February 27th to August 31st, 2020. Kruskal-Wallis and Mann-Whitney tests were used to analyze the data. Nonparametric statistics were used when data were not normally distributed. From 470 responses collected, the average horse age was 15.7 ± 7.5 years, and the most common breeds were the Quarter Horse and Thoroughbred. Of the 345 horses who received premixed feed, 81% were fed on a volume basis. Most horses (95%) received hay on a volume basis, and 57% of horses were fed hay on the ground rather than in a feeder. No difference was detected in the number of scoops of premixed feed (median = 2; P = .284) or the flakes of hay per day (median = 5.7; P = .765) between horses in different exercise categories. The frequency of reported GI issues was 10% (46/470). Owner perceived, veterinary perceived, and veterinary diagnosed ulcers were found in 2.3%, 4%, and 2.3% of horses, respectively. No statistical difference was detected in the number of scoops of premixed feed fed per day between horses with or without GI issues (P = .536). Horses were provided the same amount of premixed feed and forage regardless of reported exercise category. Most equine caretakers fed concentrates on volume rather than weight, a common practice despite most feeding requirements being based on feed weights.

The Nuts and Bolts of Health Care: Evaluating an initiative to build direct support professional capacity to support the health care of individuals with intellectual disabilities.

BACKGROUND: Direct support professionals (DSP) are instrumental in supporting the health care of individuals with intellectual disabilities, yet receive little training and support for this role. We implemented a capacity building intervention for DSPs in a community agency in Ontario, Canada. This study evaluated the perceived value and feasibility of the intervention and the value of a structured implementation approach. METHOD: The intervention included communication tools, a health resource toolkit, and training. A mixed methods evaluation was used to collect feedback from DSPs and people with intellectual disabilities. RESULTS: Participants generally found the intervention valuable and feasible. Although practice change is difficult, extensive engagement and being responsive to feedback were helpful strategies. The primary concern reported by DSPs was resistance from health care providers. CONCLUSION: An important next step is to engage health care providers to ensure the tools are valuable and feasible for everyone involved in the health encounter.

Effects of fendiline on cocaine-seeking behavior in the rat.

RATIONALE: L-type Ca(2+) channels (LTCC) and GABAB receptors are both possible targets in the development of new pharmacological compounds for cocaine addiction. Drugs that target either receptor attenuate a wide range of cocaine-seeking behaviors in the rat. However, there is no current human-approved pharmacotherapeutic intervention for psychostimulant addiction. OBJECTIVES: This study examined the effects of a human-approved LTCC blocker, fendiline, on cocaine-taking and cocaine-seeking behavior in rats. The effects of combining fendiline with the GABAB receptor agonist baclofen on cocaine self-administration were also tested. METHODS: Male Wistar rats were trained to self-administer cocaine, and the effects of fendiline pretreatment (vehicle, 1.78, 3.16, 5.62 mg/kg, intraperitoneal (IP)) were tested on progressive ratio responding and cue- and drug-induced reinstatement. The effects of baclofen (vehicle, 0.56, 1.78, 3.16, 5.62 mg/kg, IP) combined with fendiline (5.62 mg/kg, IP) were tested on progressive ratio responding. Control experiments measured locomotor activity and lever pressing for food in rats that received both baclofen and fendiline prior to the test session. RESULTS: Acute injections of fendiline prior to cue- or drug-induced reinstatement significantly attenuated lever-pressing behavior (p < 0.05). Fendiline and baclofen, but not fendiline alone, not only significantly attenuated breakpoints, but also impaired general motor behavior and naturalistic reinforcement (p < 0.05). CONCLUSION: These data suggest that the LTCC blocker fendiline may represent a novel pharmacotherapeutic intervention to prevent reinstatement to cocaine seeking. Also, co-administration of fendiline and baclofen not only can attenuate the motivation to take cocaine, but also impairs general motor behavior and naturalistic reinforcement.
