Recent clinical reports strongly support the intriguing possibility that emotional stress alone is sufficient to cause reversible myocardial dysfunction in patients. We previously reported that a combination of prenatal stress followed by restraint stress (PS+R) results in echocardiographic evidence of myocardial dysfunction in anesthetized rats compared with control rats subjected to the same restraint stress (Control+R). We now report results of our catheter-based hemodynamic studies in both anesthetized and freely ambulatory awake rats, comparing PS+R vs. Control+R. Systolic function [positive rate of change in left ventricular pressure over time (+dP/dt)] was significantly depressed (P < 0.01) in PS+R vs. Control+R both under anesthesia (6,287 +/- 252 vs. 7,837 +/- 453 mmHg/s) and awake (10,438 +/- 741 vs. 12,111 +/- 652 mmHg/s). Diastolic function (-dP/dt) was also significantly depressed (P < 0.05) in PS+R vs. Control+R both under anesthesia (-5,686 +/- 340 vs. -7,058 +/- 458 mmHg/s) and awake (-8,287 +/- 444 vs. 10,440 +/- 364 mmHg/s). PS+R also demonstrated a significantly attenuated (P < 0.05) hemodynamic response to increasing doses of the beta-adrenergic agonist isoproterenol. Intraperitoneal injection of the p38 MAP kinase inhibitor SB-203580 reversed the baseline reduction in +dP/dt and -dP/dt as well as the blunted isoproterenol response. Intraperitoneal injection of SB-203580 also reversed p38 MAP kinase and troponin I phosphorylation in cardiac myocytes isolated from PS+R. Thus the combination of prenatal stress followed by restraint stress results in reversible depression in both systolic and diastolic function as well as defective beta-adrenergic receptor signaling. Future studies in this animal model may provide insights into the basic mechanisms contributing to reversible myocardial dysfunction in patients with ischemic and nonischemic cardiomyopathies.

Premenstrual syndrome (PMS) is a complex combination of a variety of symptoms including mood swings, anxiety, depression, tender breasts and food cravings. For some women the physical pain and emotional stress are severe enough to affect their daily routines and activities. The causes of the premenstrual syndrome have not yet been understood clearly, but have been attributed to hormonal and neuronal dysbalance, diet and lifestyle. Hyperprolactinemia seems to be an important factor which is considered to be part of the endocrine disorder. Different clinical investigations and double blind trials have shown that preparations containing Vitex agnus castus fruit extract are a useful tool to decrease pathophysiologicaly increased prolactin serum levels and though could be an effective treatment for women suffering from premenstrual syndrome.

This study explores occupational therapists' (OT) perceptions of indicators for occupational therapy interventions among patients with chronic pain. An exploratory design was applied to six focus groups of OTs (n = 25) for data collection. Analysis was performed using content analysis through identification of meaning units, codes, categories and themes. Limitations of occupational performance was a major theme that included participant restrictions caused by physical, emotional and environmental barriers. Five subthemes of need were identified: 1) pain behaviour that prevented engagement in activities; 2) lack of knowledge about pain mechanisms and strategies to deal with pain; 3) occupational imbalance in work, leisure and home; 4) emotional stress and depression due to pain; and 5) physical or environmental strain resulting in limitations in occupational performance. Because of the variety and the diverse trends of approaches towards interventions for patients with chronic pain that exist in different cultures and settings, this study should be replicated in other contexts to increase the transferability of the findings.

Different aspects of personal relationships including social integration, social support, and social conflict have been related to inflammation. This article summarizes evidence linking the quality and quantity of relationships with gene expression, intracellular signaling mechanisms, and inflammatory biomarkers, and highlights the biological and psychological pathways through which close relationships impact inflammatory responses. Relationship conflict and lower social support can effectively modulate proinflammatory cytokine secretion both directly (via CNS/neural/endocrine/immune biobehavioral pathways), and indirectly, by promoting depression, emotional stress responses, and detrimental health behaviors. Accordingly, thorough assessments of health behaviors and attention to key methodological issues are necessary to identify the contributions of relationships to inflammation, and thus we highlight procedural issues to be considered in the design of studies. Despite some notable methodological challenges, the evidence suggests that learning more about how close relationships influence inflammation will provide important new insights into the ways that relationships impact health.

Early emotional stress is associated with a life-long burden of risk for later depression and stressful life events contribute to the development of depressive episodes. In this study we investigated whether childhood stress is associated with structural brain alterations in patients with major depression (MD). Forty-three patients with MD and 44 age as well as gender matched healthy control subjects were investigated using high-resolution magnetic resonance imaging (MRI). Region of interest analysis of the hippocampus, whole brain voxel-based morphometry (VBM) and assessment of childhood stress was carried out. Significantly smaller hippocampal white matter and prefrontal gray matter volume was observed in patients with MD compared to healthy controls. In particular left hippocampal white matter was smaller in patients, who had emotional childhood neglect, compared to those without neglect. For male patients this effect was seen in the left and right hippocampus. Moreover, physical neglect during childhood affected prefrontal gray matter volume in healthy subjects. Both emotional neglect and brain structural abnormalities predicted cumulative illness duration and there was a significant interaction between emotional neglect and prefrontal volumes as well as hippocampal white matter on the illness course. Childhood neglect resulted in hippocampal white matter changes in patients with major depression, pronounced at the left side and in males. Most interestingly, childhood stress and brain structure volumes independently predicted cumulative illness course. Subjects with both, structural brain changes and childhood emotional neglect seem to be at a very high risk to develop a more severe illness course.

According to the World Health Organization, approximately 220 million people worldwide have type 2 diabetes mellitus. Patients with type 2 diabetes not only have a chronic disease to cope with, they are also at increased risk for coronary heart disease, peripheral vascular disease, retinopathy, nephropathy, and neuropathy. The exact causes of type 2 diabetes are still not clear. Since the 17th century, it has been suggested that emotional stress plays a role in the etiology of type 2 diabetes mellitus. So far, review studies have mainly focused on depression as a risk factor for the development of type 2 diabetes mellitus. Yet, chronic emotional stress is an established risk factor for the development of depression. The present review provides an overview of mainly prospective epidemiological studies that have investigated the associations between different forms of emotional stress and the development of type 2 diabetes mellitus. Results of longitudinal studies suggest that not only depression but also general emotional stress and anxiety, sleeping problems, anger, and hostility are associated with an increased risk for the development of type 2 diabetes. Conflicting results were found regarding childhood neglect, life events, and work stress. It is important to emphasize that publication-bias may have occurred, resulting from "fishing-expeditions," where authors search their data for significant associations. Publication bias may also be caused by the tendency of reviewers and Editors to reject manuscripts with negative results for publication. It is therefore essential that research groups, who aim to conduct a new epidemiological cohort study, prospectively describe and publish the design of their study. Future research should focus on identifying mechanisms linking different forms of stress and incident type 2 diabetes.

High O(2) consumption, modest antioxidant defenses and a lipid-rich constitution make the brain highly vulnerable to redox imbalances. Oxidative damage in the brain causes nervous system impairment. Recently, oxidative stress has also been implicated in depression, anxiety disorders and high anxiety levels. The findings which establish a link between oxidative stress and pathological anxiety have inspired a number of other recent studies focusing on the link between oxidative status and normal anxiety and also on a possible causal relationship between cellular oxidative stress and emotional stress. This review examines the recent discoveries made on the link between oxidative status and normal anxiety levels and the putative role of oxidative stress in genesis of anxiety. We discuss the different opinions and questions that exist in the field and review the methodological approaches that are being used to determine a causal relationship between oxidative and emotional stress.

The purpose was to study age-related changes of the hypothalamic-pituitary-adrenal (HPA) axis function and their interrelations with features of cognitive aging in individuals with various type of adaptive behaviour on model of laboratory primates. Plasma cortisol (F) and dehydroepiandrosterone sulfate (DHEAS) levels in basal conditions (0900h and 2100h of day) and under acute psycho emotional stress (2-hour moderate restraint) were estimated in blood plasma of 34 young (6-8 years) and 34 old (20-27 years) female rhesus monkeys with various types of adaptive behaviour (aggressive, adequate, depressive-like). We have found that the age-related changes in HPA of monkeys of the depression-like behavior were accompanied by the maximal absolute and relative hypercortisolemia in the basal conditions as well as in the stress conditions. These disturbances in HPA are apparently associated with the higher age-related cognitive disturbances. Moreover, the young aggressive monkeys in comparison with the young monkeys of other behavior groups, demonstrated the higher levels of DHEAS and the minimal molar ratios between F and DHEAS plasma levels. For old animals with the aggressive behavior, these inter-group differences have leveled off. The minimal age-related changes in HPA and the minimal cognitive disturbances have been revealed for the monkeys with the adequate behavior. These results establish that the age-related damage of the HPA axis and the relevant age-related changes in the cognitive processes are the characteristic individual peculiarities of the animals associated with their individual features in the adaptive behavior strategy.

The goal of this review is to discuss the psychiatric aspects of pain in cancer patients from a biopsychosocial approach. Pain in cancer patients is considered as a complex reaction causing severe suffering and involves many psychological aspects. It has many dimensions such as personality, affect, cognition and social relations. The pain experience may also be influenced by some psychological factors such as anxiety, depression and the meaning of pain. Therefore, a successful management of cancer pain requires a multidisciplinary approach. Since cancer pain is generally treated medically, the psychological impact of pain is often underestimated. However, cancer pain is usually related to high levels of psychological distress. Culture, as an important factor affecting cancer pain, will also be discussed during this review. It is crucial to understand cultural diversity in the treatment of cancer patients with pain. Research shows that a minority patients of various ethnicities have less control of their pain because of the miscommunication problem within the medical setting. By paying attention to patients' cultural diversities, problems such as miscommunication causing inadequate control of pain can be eliminated. In order to manage pain in cancer patients, cognitive-behavioral interventions may be integrated with pharmacotherapy. The main goal of these strategies is to provide a sense of control and better coping skills to deal with cancer. Patients' maladaptive thoughts or behaviors may cause physical and emotional stress. Main behavioral strategies include biofeedback, relaxation training, and hypnosis. Cognitive strategies include guided imagery, distraction, thought monitoring and problem solving. By discussing all of these aspects of cancer pain, the multidimensional characteristic of pain and the relation between cancer pain and psychiatric factors will be clarified.

Emotional stress facilitates the occurrence of cardiac arrhythmias including sudden cardiac death. The prevalence of anxiety and depression is increased in cardiac patients as compared to the normal population. The risk of cardiovascular mortality is enhanced in patients suffering from depression. Comorbid anxiety disorders worsen the course of cardiac arrhythmias. Disturbance of neurocardiac regulation with predominance of the sympathetic tone is hypothesized to be causative for this. The emotional reaction to cardiac arrhythmias is differing to a large extent between individuals. Emotional stress may result from coping with treatment of cardiac arrhythmias. Emotional stress and cardiac arrhythmias may influence each other in the sense of a vicious circle. Somatoform cardiac arrhythmias are predominantly of psychogenic origin. Instrumental measures and frequent contacts between physicians and patients may facilitate disease chronification. The present review is dealing with the multifaceted relationships between cardiac arrhythmias and emotional stress. The underlying mechanisms and corresponding treatment modalities are discussed.
