Equity/inequity,stress and employee commitment in a health care setting

This article investigates the relationship between perceptions of equity, occupational stress and employee commitment in a health care setting. Significant relationships were found among these variables and implications for the health care field are discussed.     

Alcohol and sauna bathing: effects on cardiac rhythm, blood pressure, and serum electrolyte and cortisol concentrations.

The effect of heavy drinking and sauna bathing on cardiac rhythm, blood pressure, and serum electrolyte and cortisol concentrations was studied in 10 healthy male volunteers. Sauna bathing induced a comparable, significant increase in heart rate with and without alcohol consumption. During sauna bathing without alcohol, systolic blood pressure remained at the baseline level, whereas sauna and alcohol together decreased systolic blood pressure markedly from 136 +/- 4 to 113 +/- 3 mmHg (P less than 0.01). Neither sauna alone, nor sauna combined with alcohol intake, increased the frequency of premature ventricular complexes. Serum potassium, calcium and cortisol concentrations changed slightly during sauna, but alcohol consumption did not contribute further to this. In conclusion, sauna bathing, even in combination with heavy drinking, does not appear to provoke cardiac arrhythmias in healthy young men. However, the risk of hypotension is increased when sauna bathing is combined with alcohol consumption.     

Attentional Bias in Posttraumatic Stress Disorder

This study investigated preferential encoding of threat material in subjects with posttraumatic stress disorder (PTSD) with a modified dot-probe paradigm. This paradigm indexes attentional bias by measuring response latency to name neutral target words that are presented adjacent to or distant from threat words. Motor vehicle accident survivors with PTSD (n = 15), subclinical PTSD (n = 15), and low anxiety (n = 15) were required to name target words that were presented either adjacent to or distant from strong threat, mild threat, positive, and neutral words. PTSD subjects named targets faster when they were in close proximity to mild threat words. Results suggested that PTSD subjects' attention was drawn to the mild threat stimuli and are discussed in the context of network models of PTSD.     

Measurement of Perceived Disruption During Rebuilding Following Hurricane Andrew

The purpose of this study was to develop and evaluate a measure of perceived disruption during rebuilding following a disaster. Two eight-item scales, which measured intensity of disruption during the entire repair phase (Intensity-RP) and intensity of disruption during the past month (Intensity-PM) were developed and administered to 135 survivors of Hurricane Andrew. At 9 to 12 months postdisaster, Intensity-RP and Intensity-PM were both significantly associated with scores on the Global Severity Index of the SCL-90-R, and with scores on the Impact of Event-Intrusion Scale; Intensity-PM alone was significantly associated with PTSD scores. Regression analyses indicated that each scale contributed significant unique variance in predicting mental health symptoms, even after controlling for relevant demographic and initial disaster exposure variables.     

Occupational stress management programmes: a practical overview of published effect studies

There are many occupational stress management programmes availablewhich are designed to prevent and cure the negative aspectsof job-stress. The focus of the programmes can be directed towardsthe individual worker, the working group, the organization ofthe work or the organization as a whole. Moreover, programmesshow a considerable variation with respect to the type of interventionsthey promote and their underlying assumptions, as well as theirduration and costs. In this paper, effect studies of occupationalstress programmes published between 1987 and 1994 are reviewed.The aim is to give a practical overview of the variety in occupationalstress programmes, their scope, applicability and the evidenceof their effectiveness. The paper updates the review by DeFrankand Cooper published in 1989.     

Implosive therapy for the treatment of combat-related PTSD

Implosive therapy for the treatment of post-traumatic stress disorder is based on the principle of exposing the patient to trauma-related cues until there is a reduction in the anxiety associated with the cues. It is a relatively specialized procedure regarding which few clinicians receive extensive supervised training, despite the numerous case studies that demonstrate its effectiveness. The present paper addresses a number of procedural issues and offers guidelines for conducting implosive therapy with traumatized combat veterans. Elements of controversy regarding the application of implosive therapy are discussed.     

Stimulation of nerve growth factor and substance P expression in the iris–trigeminal axis of diabetic rats—involvement of oxidative stress and effects of aldose reductase inhibition

In rats with streptozotocin-induced diabetes, we measured increased (by 61%; P<0.05) mRNA for nerve growth factor (NGF) in the iris together with increased (by 82%; P<0.05) mRNA for preprotachykinin (the substance P precursor) in the trigeminal ganglion, suggesting that increased NGF was driving increased substance P gene expression. In other diabetic rats, these changes were prevented by treatment with either an antioxidant (butylated hydroxytoluene; 1% by diet) or an aldose reductase inhibitor (ARI) (sorbinil; 25 mg/kg/day p.o.) and the sorbinil treatment was associated with significant inhibition of polyol pathway intermediates in both lens and sciatic nerve. This suggests that polyol pathway activity in the lens may translate to oxidative stress-driving stimulation of NGF gene expression in the iris. The change is selective for NGF, because expression of the analogous neurotrophin, neurotrophin-3 (NT-3), was unaltered in the same irises. These changes suggest that oxidative stress and/or inflammation can drive up NGF expression in diabetes—a mechanism that might participate in iritis.     

Special issue: Group treatment after child and adolescent sexual abuse: Introduction

This introduction traces the increasing awareness of the prevalence of child sexual abuse over the last 20 years, examines the nature and consequences of such abuse and summarizes current information on the use of group treatment and its evaluation with sexually abused children and adolescents and their parents. Four examples of group treatment with different populations of abused children are described in this issue.     

STRESS IN THE RURAL EMERGENCY ROOM

ABSTRACT: This study identifies stress-producing factors reported by registered nurses (RNs) attending serious incidents in an Australian rural hospital's emergency room. A Delphi approach was used to determine the six most significant stress-producing factors, and these factors were then ranked by two groups of nurses. The rankings were compared using the Spearman Rank Order Coefficient of Correlation and were found to be dependent on years of nursing experience of the RNs taking part in the study. The more experienced group nominated 'anxiety about nursing a family member or close friend' as the most significant stress-producing factor, while the less experienced group reported 'concerns about nursing a child' as the most important stress-producing factor. Possible reasons for the variation in rankings are discussed, and recommendations are made in the light of the study's findings.
