Urinary Cortisol ELISA Kit

Workers in residential treatment centers for youth are often victims of violence, including verbally and physically aggressive behavior. Restraint and seclusion (R&S) are the last-resort methods used by residential workers to deal with the aggressive behavior of youths. However, their use has been found to contribute to building negative interactions between residential workers and youths, which can escalate to violence. To better understand the factors contributing to the use of R&S, the objective of this study was to investigate the effects of acute and chronic stress of workers as measured by psychological and physiological markers on the use of R&S in residential treatment for youth from an exploratory perspective. The data used for this study were collected from 70 workers in residential treatment centers for youths in Montreal, Canada, using questionnaires for chronic stress and salivary cortisol as measure of acute stress. Results revealed non-significant correlations and a lack of pattern in the longitudinal analyses between R&S and acute or chronic stress measures. Bayesian analyses were computed to assess the evidential value of the non-significant results. These results suggest that workers' stress may not be a significant factor associated with the use of R&S in residential treatment centers for youth.

Background/Objective:Cortisol is thought to be involved in the pathophysiology of affective disorders. Less attention has been given to other neuroendocrine factors. The aim of the present study was to test the hypothesis that adrenocortical steroids aldosterone and cortisol show different dynamic changes in the course of clinical depression with the assumption that aldosterone is a state marker of depression.Methods:A total of 78 adult subjects (39 patients with depressive disorder and 39 healthy controls) participated in a prospective non-interventional clinical study. Patients were investigated at the time of an acute episode and 6 months after reaching remission. The clinical and personal characteristics, and morning and evening salivary concentrations of aldosterone and cortisol were evaluated.Results:Patients with an acute depressive episode exhibited higher evening aldosterone and lower morning cortisol concentrations compared to healthy subjects. In these patients, both hormone concentrations showed flatter morning to evening slopes. Salivary aldosterone, but not cortisol concentrations, were lower in patients 6 months after reaching remission compared to those in the acute state. Similarly, 6 months of remission resulted in a steeper morning to evening slope of salivary aldosterone compared to the acute state. The cortisol rhythm remained dysregulated. A significant negative correlation between trait anxiety scores and morning cortisol concentrations in patients at 6 months of clinical remission was observed.Conclusion:Diurnal changes in salivary aldosterone concentrations appear to be a state marker, whilst those of cortisol a trait marker of depression.
