Therapeutic Settings

Only a few studies have investigated the welfare of animals participating in animal-assisted interventions (AAIs). Most of these studies focus on dogs in therapeutic settings. There are, however, also dogs—service dogs—that are employed to continuously support a single human. Because the welfare of these service dogs is important for the sustainability of their role, the aim of this study was to investigate their stress response to service dog training sessions. To do this, we took repeated salivary cortisol samples from dogs who participated in a training session (n = 19). Samples were taken just after arrival at the training ground, before training, after training, and after a period of free play. Our results showed that mean cortisol levels in all samples were relatively low (between 1.55 ± 1.10 and 2.73 ± 1.47 nmol/L) compared to similar studies. Analysis further showed that samples taken before and after participation in the training’s session did not differ from one another. Mean cortisol levels in both situations were additionally lower than those upon arrival at the training site and after a period of free play. This led to the conclusion that the dogs in our study did not seem to experience training as stressful.

Although mental disorders are common among university students, the majority of students with mental health issues do not seek out treatment during their academic life. The aim of this study was to evaluate the effects of a novel group approach- choir singing, and its potential impact on stress, via salivary cortisol levels and self-reported stress levels in university students during 4 sessions of choir singing. It was based on a quasi-experimental research conducted with 25 Brazilian university students. Each choir singing session lasted 60 minutes. A question was asked before and after the intervention: what is the level of your stress? Salivary cortisol was collected before and after the intervention. After the choir singing intervention, there was  a statistically significant reduction in self-reported stress (p<0.0001) and salivary cortisol levels (p<0.0001). This research suggests that choir singing can reduce the self-reported stress of university students after 4 weeks of follow-up with ∆= 45.83% and salivary cortisol levels in the first week with ∆= 3.57%.

Immediately before and after participation in a written final examination, 11 graduate students rated their self-perceived stress and provided saliva samples for cortisol assay. Students rated stress higher before the examination, and these ratings were associated with increased salivary cortisol. Students who reported higher stress and had higher cortisol levels before the examination tended to have significantly lower examination scores.

Objectives: The objective of the study was to assess the behavioral effects and the changes in the anxiety level of children after intranasal and sublingual midazolam sedation using Venham's clinical anxiety scale and salivary cortisol level. Study Design: Twenty children aged 3 to 7 years were randomly assigned to Group A (n=10) intranasal or Group B (n=10) sublingual midazolam (0.2mg/kg) sedation. The anxiety levels at various time periods were assessed using Venham clinical anxiety scale and corresponding changes in salivary cortisol levels were assessed before and after the drug administration. The anxiety levels were assessed independently by two pediatric dentists from recorded videos. Wilcoxon signed rank test and Mann Whitney U test were used for statistical analysis using SPSS version 19.0.Results: There was a significant decrease in anxiety level from baseline to 20 minutes after drug administration in group A (p=0.004) and group B (p=0.003). There was no significant change in salivary cortisol levels before and after the drug administration in group A (p=0.07) and group B (p=0.38). Conclusions: Both intranasal and sublingual administration of midazolam was equally effective in reducing the child's anxiety. However, there was no significant difference in the salivary cortisol levels in both groups.

Abstract Objectives There is evidence suggesting that in martial arts competitions athletes characterized by higher anxiety and harm avoidance may be more likely to lose a fight. This psychological profile has been hypothesized to explain in part the observation that cortisol is higher in losers before and in response to a competition. An important research target that needs further exploration is the identification of phenotypic traits that can be helpful in predicting athletes’ performance. Here we present a brief description of the theoretical bases that drives our research in the evolutionary psychobiology of sports and illustrate preliminary data on the relationship between the 5HTTLPR genotype, salivary cortisol, temperament and competition. Methods Sixty-five healthy male non-professional athletes provided saliva samples 10 min before and after a kumite session and filled out the Tridimensional Personality Questionnaire. Results Salivary cortisol levels 10 min before the competition were higher in losers and in athletes with the S allele. Temperament was associated with competition outcome and cortisol: losers were characterized by higher scores of harm avoidance and harm avoidance was positively correlated with cortisol levels. Conclusions The results confirm previous findings linking temperamental traits, pre-and post- competition physiological stress response with competition outcome in kumite fight. Moreover, they indicate an association between the 5HTTLPR polymorphism and pre-competition salivary cortisol, thus providing a preliminary but non-conclusive evidence on the role played by the 5HTTLPR genotype as a vulnerability factor in sport competition.

In a previous paper (Hodges, Jones, Elithorn and Bridges, 1964) we reported on adrenocortical activity in depressed and schizophrenic patients as revealed by plasma cortisol levels before and after electro-convulsive therapy (E.C.T.). Close similarity was found between the two groups except for three depressed patients who appeared to show considerably higher cortisol levels after the treatment than did the remaining subjects. The patients were examined at random different treatments during the whole treatment course and it appeared possible, both that the observed cortisol response to E.C.T. might depend partly on which treatment of the series in a whole course was under examination, and also that the response of the illness to therapy might be a significant factor. It was therefore decided to observe in a number of subjects the response to successive treatments throughout courses of E.C.T.

The Difference

Summary Background: Salivary cortisol measurement is a non-invasive method suitable for use in neonatal research. Mother-infant separation after birth represents stress and skin-to-skin contact (SSC) has numerous benefits. The aim of the study was to measure salivary cortisol in mothers and newborns before and after SSC in order to assess the effect of SSC on mothers’ and infants’ stress and to estimate the efficacy of collecting small saliva samples in newborns. Methods: Salivary cortisol was measured in 35 mother-infant pairs before and after the first and the fifth SSC in small saliva samples (50 μL) using the high sensitivity Quantitative ELISA-Kit (0.0828 nmol/L) for low cortisol levels detection. Samples were collected with eye sponge during 3 to 5 minutes. Results: Cortisol level in mothers decreased after SSC: the highest levels were measured before and the lowest after SSC and the differences in values were significant during both the first (p<0.001) and the fifth SSC (p<0.001). During the first SSC the cortisol level decrease was detected in 14 (40%) and an increase in 21 (60%) newborns, and during the fifth SSC a decrease was detected in 16 (45.7%) and an increase in 19 (54.3%) newborns, without confirmed significance of the difference. Saliva sampling efficacy using eye sponge was 75%. Conclusions: Cortisol level decrease in mothers proves the stress reduction during SSC, while variable cortisol levels in infants do not indicate stress reduction and imply the need for further research. The used sampling method appeared to be one of the most optimal considering the sample volume, sampling time and efficacy.

Past research on the relation between hostility in intimate relationships and adiposity has yielded mixed findings. The present study investigated whether the association between relationship hostility and adiposity is moderated by people’s biological reactions to couple conflict. Cohabiting adult couples (N = 117 couples) engaged in two conflict interactions, before and after which salivary cortisol levels were measured. Results revealed an association between relationship hostility and adiposity, but this association was concentrated among people with relatively low levels of cortisol reactivity to couple conflict. Results are interpreted in light of research demonstrating that cortisol reactivity can become blunted over time in response to repeated stressors. These results provide precision to etiological models of obesity by identifying cortisol reactivity as a factor that moderates the association between relationship hostility and adiposity.

Purpose: The effects of breastfeeding on postpartum depression symptoms and stress using physiological measures require investigation. Background: Breastfeeding suppresses the secretion of cortisol. Oxytocin levels correlate negatively with symptoms of postpartum depression. Aim: To investigate the effects of breastfeeding on stress and postpartum depression. Methods: We examined 79 breastfeeding women using the Edinburgh Postnatal Depression Scale, the Perceived Stress Scale-10, and the Breastfeeding Self-Efficacy Scale, and measured the salivary cortisol levels before and after breastfeeding. Findings: There was a negative correlation between the duration of suckling and changes in salivary cortisol levels following breastfeeding (rs = −0.333, p < 0.05). Salivary cortisol levels immediately following breastfeeding were significantly lower compared to mothers who used mixed feeding methods (p < 0.001). Breastfeeding mothers had lower perceived stress than mothers using mixed feeding methods (β = −0.260, p < 0.05). There was no association between breastfeeding and postpartum depression; however, there was an association between postpartum depression and perceived stress (β = 0.622, p < 0.001). Conclusion: Salivary cortisol levels significantly decreased following breastfeeding, with longer suckling times correlating with lower cortisol levels. Breastfeeding reduced stress and increased breastfeeding self-efficacy.
