Impact of Human-Animal Interactions on Psychological and Physiological Factors Associated With Veterinary School Students and Donkeys.

There has been an increased interest in evaluating human-animal interactions and assessing the mutual health and wellbeing. In this study, first-year female and male veterinary school students not paired (n = 58) or paired (n = 25) with immature (≤9 mo) donkeys (n = 13) were engaged in three different types of interactions (1st, hands-off remote learning, 2nd, hands-on passive learning, and 3rd, hands-on active learning) for 30 min each during Week 2 (Time 1), Weeks 5-8 (Time 2), and Week 12 (Time 3) over three, 15-week periods. Student psychological data involved the Penn State Worry Questionnaire (PSWQ) scores collected from the interactive (student-donkey pairs) and non-interactive (no student-donkey pairs) groups and modified Comfort from Companion Animals Scale (CCAS) scores collected from the interactive group during Times 1, 2, and 3. Donkey physiological data involved collection of saliva within 10 min pre- and post-interaction during Times 1, 2, and 3 in association with the different types of interactions for immunoanalysis of cortisol. There were no significant effects of the various times and types of interactions on CCAS scores. While there were no significant effects of group and types of interactions on PSWQ scores, there was an effect (P = 0.01) of time. Overall mean PSWQ scores were significantly lower during Week 12 versus Week 2. Correspondingly, while there were no effects pre- vs. post-interaction within or among times on saliva cortisol concentrations in donkeys, there was an effect (P = 0.02) of the type of interaction. Mean concentrations were significantly lower with the hands-on passive and hands-on active learning versus the hands-off remote learning. In conclusion, while this study provides preliminary evidence surrounding student donkey interactions, future studies are required with more comprehensive designs to clarify these benefits and better understand the advantages and challenges surrounding student-donkey interactions.

Saliva versus serum cortisol to identify subclinical hypercortisolism in adrenal incidentalomas: simplicity versus accuracy.

PURPOSE: Subclinical hypercortisolism (SCH) leads to metabolic derangements and increased cardiovascular risk. Cortisol autonomy is defined by the overnight 1 mg dexamethasone suppression test (DST). Saliva cortisol is an easier, stress-free, and cost-effective alternative to serum cortisol. We compared 23 h and post-1 mg DST saliva with serum cortisol to identify SCH in adrenal incidentalomas (AI). METHODS: We analyzed 359 DST obtained retrospectively from 226 AI subjects (173F/53 M; 19-83 years) for saliva and serum cortisol. We used three post-DST serum cortisol cutoffs to uncover SCH: 1.8, 2.5, and 5.0 µg/dL. We determined post-DST and 23 h saliva cortisol cutoffs by ROC curve analysis and calculated their sensitivities (S) and specificities (E). RESULTS: The sensitive 1.8 µg/dL cutoff defined 137 SCH and 180 non-functioning adenomas (NFA): post-DST and 23 h saliva cortisol S/E were: 75.2%/74.4% and 59.5%/65.9%, respectively. Using the specific 5.0 µg/dL cortisol cutoff (22 SCH/295 NFA), post-DST and 23 h saliva cortisol S/E were 86.4%/83.4% and 66.7%/80.4%, respectively. Using the intermediate 2.5 µg/dL cutoff (89 SCH/228 NFA), post-DST and 23 h saliva cortisol S/E were 80.9%/68.9% and 65.5%/62.8%, respectively. CONCLUSION: Saliva cortisol showed acceptable performance only with the 5.0 µg/dL cortisol cutoff, as in overt Cushing's syndrome. Lower cutoffs (1.8 and 2.5 µg/dL) that identify larger samples of patients with poor metabolic outcomes are less accurate for screening. These results may be attributed to pre-analytical factors and inherent patient conditions. Thus, saliva cortisol cannot replace serum cortisol to identify SCH among patients with AI for screening DST.

Mind-body therapies: an intervention to reduce work-related stress in veterinary academia.

Studies investigating perceived stress and mindfulness awareness support mind-body therapy (MBT) effectiveness in reducing stress and anxiety and, thus, has potential to decrease work-related stress. A pre/postexperimental design involved 30 faculty and staff working at Ross University School of Veterinary Medicine, Saint Kitts and Nevis, who experienced a two-day MBT intervention programme. An additional 16 faculty and staff not involved in MBT who went about their daily work schedules served as contemporary controls. Demographics, Perceived Stress Scale 10 (PSS-10), Mindful Attention Awareness Scale (MAAS), 16 Personality Factor (16PF) Openness to Change subscale and saliva cortisol concentrations were analysed. Control participants reported significantly perceived less stress (PSS-10: M=13; sd=1.4) than intervention participants (M=20; sd=6.6) during pretest. However, at post-test the intervention group reported a significant decrease in perceived stress (M=11; sd=6.0). MAAS pretest results indicated the intervention group displayed a lower average score (M=54; sd=15.3) than control participants (M=68; sd=2.0). Post-MAAS intervention scores showed improvements in mindfulness (M=63; sd=15.3). Correlations between the 16PF Openness to Change subscale and MAAS were r=0.03 and r=-0.17 for the intervention and control groups, respectively. Mean concentrations of saliva cortisol indicated a larger and significant decline in cortisol for the intervention group both during day 1 (P=0.0001) and day 2 (P=0.0008). In conclusion, these preliminary results provide support that MBTs in veterinary academia can improve psychological and physiological aspects of personal wellbeing.
