In spite of advances in understanding the cross-talk between the peripheral immune system and the brain, the molecular mechanisms underlying the rapid adaptation of the immune system to an acute psychological stressor remain largely unknown. Conventional approaches to classify molecular factors mediating these responses have targeted relatively few biological measurements or explored cross-sectional study designs, and therefore have restricted characterization of stress-immune interactions. This exploratory study analyzed transcriptional profiles and flow cytometric data of peripheral blood leukocytes with physiological (endocrine, autonomic) measurements collected throughout the sequence of events leading up to, during, and after short-term exposure to physical danger in humans. Immediate immunomodulation to acute psychological stress was defined as a short-term selective up-regulation of natural killer (NK) cell-associated cytotoxic and IL-12 mediated signaling genes that correlated with increased cortisol, catecholamines and NK cells into the periphery. In parallel, we observed down-regulation of innate immune toll-like receptor genes and genes of the MyD88-dependent signaling pathway. Correcting gene expression for an influx of NK cells revealed a molecular signature specific to the adrenal cortex. Subsequently, focusing analyses on discrete groups of coordinately expressed genes (modules) throughout the time-series revealed immune stress responses in modules associated to immune/defense response, response to wounding, cytokine production, TCR signaling and NK cell cytotoxicity which differed between males and females. These results offer a spring-board for future research towards improved treatment of stress-related disease including the impact of stress on cardiovascular and autoimmune disorders, and identifies an immune mechanism by which vulnerabilities to these diseases may be gender-specific.

This study was aimed to compare the effects of acute and chronic psychological stress on metabolic factors.Forty-two male Wistar rats were divided into control and stressed groups.Stress was applied by a communication box acutely (1 d) and chronically (15 and 30 d).Blood sampling was carried out by retro-orbital-puncture method.The plasma levels of glucose,cholesterol,triglyceride,insulin,and corticosterone were measured.In addition,feed and water intake,latency to eat and drink,adrenal and body weights were determined.Acute and chronic psychological stress did not significantly change basal plasma corticosterone levels.However,immediately (1 min) after acute exposure to stress,plasma corticosterone level increased compared to that before stress exposure.Acute stress increased plasma insulin levels significantly.Fifteen days of stress exposure resulted in plasma glucose increase.Chronic stress significantly increased feed intake,latency to eat,and adrenal weight compared to acute stress.The body weights of both control and stressed groups increased markedly during the experiment.Homeostasis model assessment of insulin resistance (HOMA-IR) index did not change significantly in the stressed group.In conclusion,application of acute and chronic psychological stress leads to different metabolic and/or behavioral changes but the metabolic changes resulting from acute exposure to stress seem to be more pronounced.

peer-reviewed Background: Exaggerated cardiovascular reactions to psychological stress are considered a risk factor for cardiovascular morbidity. Social support may reduce such risk by attenuating cardiovascular reactivity to stress. Purpose: To examine the effects of three independent social support variables and their interaction on cardiovascular reactivity to acute stress. The variables were stranger or friend presence; active supportive or passive presence, and male or ...

Caring for an offspring with an eating disorder (ED) is associated with high levels of distress, and health problems. Indeed, ED caregivers have to cope with a range of challenges related to their caring role, which represents a chronic stress situation. This tends to alter body homeostasis and caregivers' health status. This study aimed to analyse the electrodermal reactivity and psychological response to acute stress in ED caregivers compared to non-caregivers. As expected, caregivers showed lower electrodermal (p < .001, η2partial = .269 for SCL and p < .01, η2partial = .214 for NSCRs) and psychological response (p < .05, η2partial = .198) to acute stress than non-caregivers. The findings suggest the existence of physiological adaptation to chronic stress in family caregivers of people with EDs. PMID:27160010

Physiological reactions to psychological stress are positively associated with several important chronic conditions including cardiovascular and neurodegenerative diseases and are linked to increased mortality. As such, the identification of cellular and molecular pathways that act to reduce stress responding may represent important targets for therapeutic intervention. Here we report that acute treatment with the peroxisome-proliferator activated receptor-γ (PPARγ) agonist rosiglitazone (RSG...

Platelet reactivity to acute stress is associated with increased cardiovascular disease risk; however, little research exists to provide systematic methodological foundations needed to generate strong longitudinal research designs. Study objectives were: 1) to evaluate whether markers of platelet function increase in response to an acute psychological stress test among older adults, 2) to establish whether reactivity remains robust upon repeated administration (i.e. three occasions approximately 1 year apart), and 3) to evaluate whether two different acute speech stress tasks elicit similar platelet responses. The 149 subjects (mean age 71 years) gave a brief impromptu speech on one of two randomly assigned topics involving interpersonal conflict. Blood samples drawn at baseline and post-speech were assayed using flow cytometry for platelet responses on three outcomes (% aggregates, % P-selectin expression, and % fibrinogen receptor expression). Three-level hierarchical linear modeling analyses revealed significant stress-induced increases in platelet activation on all outcomes (p < 0.001). No significant habituation on any measure was found. Additional reactivity differences were associated with male gender, history of myocardial infarction, and use of aspirin, statins, and antidepressants. The results demonstrate that laboratory acute stress tests continued to produce robust platelet reactivity on three activation markers among older adults over 3 years. PMID:19096987

Low or blunted cardiovascular and cortisol reactions to acute psychological stress have been shown to characterise those with a tobacco or alcohol dependency. The present study tested the hypothesis that exercise dependency would be similarly associated with blunted reactivity. Young female exercisers (N = 219) were screened by questionnaire for exercise dependence. Ten women with probable exercise dependence and 10 non dependent controls were selected for laboratory stress testing....
There is an enormous amount of literature on psychological stress and cardiovascular disease. This report reviews conceptual issues in defining stress and then explores the ramifications of stress in terms of the effects of acute versus long-term stressors on cardiac functioning. Examples of acute stressor studies are discussed in terms of disasters (earthquakes) and in the context of experimental stress physiology studies, which offer a more detailed perspective on underlying physiology.

The experience of psychological stress triggers neuroendocrine, inflammatory, metabolic, and transcriptional perturbations that ultimately predispose to disease. However, the subcellular determinants of this integrated, multisystemic stress response have not been defined. Central to stress adaptation is cellular energetics, involving mitochondrial energy production and oxidative stress. We therefore hypothesized that abnormal mitochondrial functions would differentially modulate the organism's multisystemic response to psychological stress. By mutating or deleting mitochondrial genes encoded in the mtDNA [NADH dehydrogenase 6 (ND6) and cytochrome c oxidase subunit I (COI)] or nuclear DNA [adenine nucleotide translocator 1 (ANT1) and nicotinamide nucleotide transhydrogenase (NNT)], we selectively impaired mitochondrial respiratory chain function, energy exchange, and mitochondrial redox balance in mice. The resulting impact on physiological reactivity and recovery from restraint stress were then characterized. We show that mitochondrial dysfunctions altered the hypothalamic-pituitary-adrenal axis, sympathetic adrenal-medullary activation and catecholamine levels, the inflammatory cytokine IL-6, circulating metabolites, and hippocampal gene expression responses to stress. Each mitochondrial defect generated a distinct whole-body stress-response signature. These results demonstrate the role of mitochondrial energetics and redox balance as modulators of key pathophysiological perturbations previously linked to disease. This work establishes mitochondria as stress-response modulators, with implications for understanding the mechanisms of stress pathophysiology and mitochondrial diseases. PMID:26627253
Full Text Available Background: Psychological stress following natural disaster is common. Despite several earthquakes in India, data on evaluation of acute stress among the child victims in the early postdisaster period is scarce. Immediately following a devastating earthquake (6.9 Richter at Sikkim on September, 18 2011, many children attended North Bengal Medical College, the nearest government tertiary care institution, with unusual stress symptoms. Objective: Evaluation of acute stress symptoms in children in the immediate postearthquake period. Materials and Methods: This was a cross-sectional study done over 4 weeks and includes all the children from 1 to 12 years presenting with unusual physical or behavioral symptoms. Those with major injuries requiring admission were excluded. They were divided into two age groups. For older children (8-12 years the 8-item Children Impact of Event Scale (CIES was used for screening of stress. Unusual symptoms were recorded in younger children (1-8 years as CIES is not validated < 8 years. Result: A total of 84 children (2.66% out of 3154 had stress symptoms. Maximum attendance was noted in first 3 days (65.47% and declined gradually. In children ≥ 8 years, 48.78% had psychological stress, which was statistically significant on CIES scores without any gender predilection. Static posturing (41.86%, sleeplessness (32.55%, anorexia (9.30%, recurrent vomiting (13.95%, excessive crying (13.95%, or night-awakenings (4.65% were found in younger children ( n = 43 and three required admission. Conclusion: This study represent the first Indian data showing statistically significant psychological impact in older children (8-12 years and various forms of physical stress symptoms in young children (1-8 years following earthquake.
Full Text Available BACKGROUND: Many acute coronary syndrome (ACS; myocardial infarction and unstable angina patients are rehospitalized within 30 days of discharge, and recent US health policy initiatives have tied hospital Medicare reimbursement to 30-day readmission rates. Patient-perceived psychological stress is thought to impact prognosis after ACS. A recently offered "posthospital syndrome" model of 30-day readmissions posits that the stress level at the time of the index hospitalization itself may increase 30-day risk for readmission in ACS patients. We tested whether self-reported stress in the days surrounding the ACS hospitalization was associated with increased risk for readmission within 30 days. METHODS: A mean of 8.5 days after discharge, 342 consecutively hospitalized ACS patients reported on how often they felt stress during the past two weeks. Readmission within 30 days of hospital discharge for any cause was determined by follow-up telephone calls to patients and confirmed by hospital records. RESULTS: Overall, 40 (11.7% participants were readmitted within 30 days, and 22 (6.4% reported high stress. Readmission within 30 days was more common in patients with high stress (5 admissions, 23% than in patients with low stress (35 admissions, 11%. After adjustment for demographic and clinical factors, as well as depression, high stress was associated with a 3-fold increased risk of 30-day readmission (HR = 3.21, 95% CI = 1.13, 9.10. CONCLUSIONS: Previous research has shown that stress in the days surrounding a hospitalization can mark long-term cardiovascular risk, but this is the first study to test a hypothesis of the posthospital syndrome model of early readmission. Further research is needed to confirm the association between stress and readmission risk, and to identify the processes of hospitalization that could be modified to both reduce the stress experienced and that would also be effective for reducing readmissions.
Full Text Available Ghrelin is a growth hormone and cortisol secretagogue that plays an important role in appetite and weight regulation. It is not known whether ghrelin is involved in the eating response to stress in humans. In the present study we examined the effects of psychologically induced stress on plasma ghrelin levels in patients with bingeeating disorder (BED and in healthy subjects of normal or increased body mass index (BMI. Volunteers were subjected to the standardized trier social stress test (TSST. Basal ghrelin levels in patients were at an intermediate level between thin and healthy obese subjects, but this difference did not attain statistical significance. There were no differences in ghrelin levels throughout the test among the groups after correction for BMI, age and gender. A significant difference in the trend time of ghrelin was revealed when the three groups were analyzed according to their cortisol response to stress. Ghrelin levels increased in cortisol responders whereas no change or a decrease in ghrelin levels occurred in cortisol non-responders. We also found Optimal time T*, Minimal Repair δ and Random Lead Time g to minimize the ghrelin level.

Uveitis is an inflammatory condition affecting the eye and is often associated with systemic autoimmune disease. A role for the involvement of psychological stress in autoimmune disease has been widely demonstrated. However, uveitis is not classified as an autoimmune disease, and a definite or direct cause has yet to be identified, although infection may be involved. Many uveitis patients retrospectively report stressful life events occurring prior to the onset or recurrence of uveitis. Howev...

Full Text Available The present study was undertaken to evaluate the adaptogenic activity of ethanol (EtHI, ethyl acetate (EAHI fractions of Habenaria intermedia D. Don, Orchidaceae (HI, tubers using immobilization induced acute stress (AS, chronic stress (CS and swimming induced stress in experimental animals. The tested doses of EtHI (100 and 200 mg/kg, p.o. and higher dose of EAHI (200 mg/kg, p.o. normalized altered serum biochemical parameters and the severity of ulcers in both AS and CS. EAHI and EtHI restored the hyperthrophy of adrenal gland and atrophy of spleen and thymus gland in AS and CS. Greater swimming time was noted in the mice pretreated with EtHI and EAHI. Levels of adrenal ascorbic acid and cortisol were restored significantly. EAHI exhibited prominent scavenging effect of DPPH, hydroxyl radical and lipid peroxidation in vitro. Phytochemical studies resulted in the isolation of scopoletin and gallic acid as marker compounds. Our results proved the traditional claim of HI as anti-stress/adaptogen in Ayurvdea.

Recent evidence demonstrates that individuals with low heart rate (HR) reactions to acute psychological stress are more likely to be obese or smokers. Smoking and obesity are established risk factors for increased carotid intima-media thickness (IMT). The aim of this study was to examine the potential pathways linking intima-media thickness, smoking, body mass index (BMI), and HR stress reactivity. A total of 552 participants, 47.6% male, M (SD) age = 58.3 (0.94) years, were exposed to three psychological stress tasks (Stroop, mirror drawing, and speech) preceded by a resting baseline period; HR was recorded throughout. HR reactivity was calculated as the average response across the three tasks minus average baseline HR. Smoking status, BMI, and IMT were determined by trained personnel. Controlling for important covariates (e.g., socioeconomic status), structural equation modeling revealed that BMI and smoking mediated the negative relationship between HR reactivity and IMT. The hypothesized model demonstrated a good overall fit to the data, χ(2) (8) = 0.692, p = .403; CFI = 1.00; TLI = 1.00 SRMR = .01; RMSEA < .001 (90% CI < 0.01-0.11). HR reactivity was negatively related to BMI (β = -.16) and smoking (β = -.18), and these in turn were positively associated with IMT (BMI: β = .10; smoking: β = .17). Diminished HR stress reactivity appears to be a marker for enlarged IMT and appears to be exerting its impact through already established risks. Future research should examine this relationship longitudinally and aim to intervene early. PMID:27005834

Myocardial Infarction - Stress PRevention INTervention (MI-SPRINT) to reduce the incidence of posttraumatic stress after acute myocardial infarction through trauma-focused psychological counseling: study protocol for a randomized controlled trial
Background Posttraumatic Stress Disorder (PTSD) may occur in patients after exposure to a life-threatening illness. About one out of six patients develop clinically relevant levels of PTSD symptoms after acute myocardial infarction (MI). Symptoms of PTSD are associated with impaired quality of life and increase the risk of recurrent cardiovascular events. The main hypothesis of the MI-SPRINT study is that trauma-focused psychological counseling is more effective than non-trauma focused counseling in preventing posttraumatic stress after acute MI. Methods/Design The study is a single-center, randomized controlled psychological trial with two active intervention arms. The sample consists of 426 patients aged 18 years or older who are at 'high risk’ to develop clinically relevant posttraumatic stress symptoms. 'High risk’ patients are identified with three single-item questions with a numeric rating scale (0 to 10) asking about 'pain during MI’, 'fear of dying until admission’ and/or 'worrying and feeling helpless when being told about having MI’. Exclusion criteria are emergency heart surgery, severe comorbidities, current severe depression, disorientation, cognitive impairment and suicidal ideation. Patients will be randomly allocated to a single 45-minute counseling session targeting either specific MI-triggered traumatic reactions (that is, the verum intervention) or the general role of psychosocial stress in coronary heart disease (that is, the control intervention). The session will take place in the coronary care unit within 48 hours, by the bedside, after patients have reached stable circulatory conditions. Each patient will additionally receive an illustrated information booklet as study material. Sociodemographic factors, psychosocial and medical data, and cardiometabolic risk factors will be assessed during hospitalization. The primary outcome is the interviewer-rated posttraumatic stress level at three-month follow-up, which is hypothesized to be

Psychological stress affects human health, and chronic stress leads to life-threatening diseases, such as depression and post-traumatic stress disorder. Psychological stress coping mechanisms involve the brain-derived neurotrophic factor (BDNF) and downstream cAMP response element binding protein (CREB), which are targets of the adverse effects of stress paradigms. Fourty-seven adult male Sprague-Dawley rats were divided into control, physical stress and six psychological stress groups which were assayed at 0h, 0.5h, 1h, 2h, 6h and 24h after communication box (CB) stress induction. Behavioral assessment using open field and elevated plus maze tests determined that CB stress significantly increased anxiety. After CB stress, the alternation of mRNA levels of BDNF and CREB were assessed at different time points by in situ hybridization. The mRNA levels of BDNF and CREB were significantly decreased, then gradually recovered over 24h to maximum levels in the hippocampus (CA1 region), prefrontal cortex (PFC), central amygdaloid nuclei (AG), shell of accumbens nucleus (NAC), periaqueductal gray (PAG) and ventral tegmental area, except for the ventral tegmental area (VTA). Moreover, mRNA levels of BDNF and CREB were positively correlated in all examined brain regions, except for the VTA region at 0 and 24h after CB stress induction. These findings suggest that BDNF and CREB may belong to the same pathway and be involved in psychological stress response mechanisms, and protect the organism from stress induced, aversive processes leading to disease.

Research in cognitive psychology has made a significant contribution to our understanding of how acute and chronic stress affect performance. It has done so by identifying some of the factors that contribute to operator error and by suggesting how operators might be trained to respond more effectively in a variety of circumstances. The major purpose of this paper was to review the literature of cognitive psychology as it relates to these questions and issues. Based on the existence of earlier reviews (e.g., Hamilton, & Warburton, 1979; Hockey, 1983) the following investigation was limited to the last 15 years (1988-2002) and restricted to a review of the primary peer-reviewed literature. The results of this examination revealed that while cognitive psychology has contributed in a substantive way to our understanding of stress impact on various cognitive processes, it has also left many questions unanswered. Concerns about how we define and use the term stress and the gaps that remain in our knowledge about the specific effects of stressors on cognitive processes are discussed in the text.

Full Text Available Emergency work can expose personnel to sleep restriction. Inadequate amounts of sleep can negatively affect physiological and psychological stress responses. This review critiqued the emergency service literature (e.g., firefighting, police/law enforcement, defense forces, ambulance/paramedic personnel that has investigated the effect of sleep restriction on hormonal, inflammatory and psychological responses. Furthermore, it investigated if a psycho-physiological approach can help contextualize the significance of such responses to assist emergency service agencies monitor the health of their personnel. The available literature suggests that sleep restriction across multiple work days can disrupt cytokine and cortisol levels, deteriorate mood and elicit simultaneous physiological and psychological responses. However, research concerning the interaction between such responses is limited and inconclusive. Therefore, it is unknown if a psycho-physiological relationship exists and as a result, it is currently not feasible for agencies to monitor sleep restriction related stress based on psycho- physiological interactions. Sleep restriction does however, appear to be a major stressor contributing to physiological and psychological responses and thus, warrants further investigation.
Full Text Available Several theoretical models have been occasionally proposed to account for the involvement of psychological factors in cancer genesis. Family environment and relations as well as certain personality traits were correlated to cancer onset. However, little is known in the case of acute leukemia. The present study examined family environment, state-trait anxiety, hostility and the direction of hostility as well as alexithymia in 41 acute leukemia patients and their first degree relatives (70. In accordance with previous findings, the present results showed that family cohesion, conflict and organization as well as guilt, state anxiety and alexithymia were significant risk factors for the development of the disease.

Cardiovascular disease (CVD) is the largest cause of mortality worldwide, and stress is a significant contributor to the development of CVD. The relationship between acute and chronic stress and CVD is well evidenced. Acute stress can lead to arrhythmias and ischemic injury. However, recent evidence in rodent models suggests that acute stress can decrease sensitivity to myocardial ischemia–reperfusion injury (IRI). Conversely, chronic stress is arrhythmogenic and increases sensitivity to myocardial IRI. Few studies have examined the impact of validated animal models of stress-related psychological disorders on the ischemic heart. This review examines the work that has been completed using rat models to study the effects of stress on myocardial sensitivity to ischemic injury. Utilization of animal models of stress-related psychological disorders is critical in the prevention and treatment of cardiovascular disorders in patients experiencing stress-related psychiatric conditions.

Audio tape recordings of selected Skylab communications were processed by a psychological stress evaluator. Strip chart tracings were read blind and scores were assigned based on characteristics reported by the manufacturer to indicate psychological stress. These scores were analyzed for their empirical relationships with operational variables in Skylab judged to represent varying degrees of situational stress. Although some statistically significant relationships were found, the technique was not judged to be sufficiently predictive to warrant its use in assessing the degree of psychological stress of crew members in future space missions.

Many important decisions are made under stress and they often involve risky alternatives. There has been ample evidence that stress influences decision making in cognitive as well as in affective domains, but still very little is known about whether individual attitudes to risk change with exposure to acute stress. To directly evaluate the causal effect of stress on risk attitudes, we adopt an experimental approach in which we randomly expose participants to a psychosocial stressor in the for...

The purpose of this study was to investigate the association between repressive coping style and Acute Stress Disorder (ASD) in a sample of cancer patients. A total of 112 cancer patients recently diagnosed with cancer participated in the study. ASD was assessed by the Stanford Acute Stress...... Reaction Questionnaire, and repressive coping was assessed by a combination of scores from the Marlowe-Crowne Social Desirability Scale, and the Bendig version of the Taylor Manifest Anxiety Scale. Significantly fewer patients classified as "repressors" were diagnosed with ASD compared to patients...... classified as "non-repressors". However, further investigations revealed that the lower incidence of ASD in repressors apparently was caused by a low score on anxiety and not by an interaction effect between anxiety and defensiveness. Future studies have to investigate whether different psychological...

Conclusion: The study revealed that symptoms of posttraumatic stress disorder increased after pregnancy losses. It is of great importance to provide social and psychological support for the couples experiencing a pregnancy loss in terms of their wellbeing. Inability to implement support mechanisms effectively in cases of increased acute stress such as pregnancy loss can predispose to progression to posttraumatic stress disorder.

Toward the development of a unifying diagnosis for acute stress responses this article attempts to find a place for combat stress reaction (CSR) within the spectrum of other defined acute stress responses. This article critically compares the diagnostic criteria of acute stress disorder (ASD), acute stress reaction (ASR), and CSR. Prospective studies concerning the predictive value of ASD, ASR, and CSR are reviewed. Questions, recommendations, and implications for clinical practice are raised concerning the completeness of the current acute stress response diagnoses, the heterogeneity of different stressors, the scope of expected outcomes, and the importance of decline in function as an indicator of future psychological, psychiatric, and somatic distress.

This paper generally describes personality structure and needs and then relates these to the psychological aspects of radiation injury. Three levels in the personality structure are defined as child, adult, and parent. This is followed by a description of two major need systems the first of which, if not met, results in the death of the individual and the second, if not met, results in significant emotional disruption of the individual. This is followed by a discussion of coping phases and stress patterns of radiation injury, including the effects of the illusion of immunity characterized by the feeling that ''things can happen to others, but not to me'', and the ''nuclear mystique'' which is characterized by a magical quality attached to radiation due partly to the lack of sense organ response to radiation exposure. Following impact, treatment in the reactive.phase, which includes moderate and severe emotional reactions, involves a series of compensating emotions. These include the illusion of centrality, the feeling of abandonment, altruism, and amorality. The ''aftermath'' reaction is treated from the standpoint of the ''tormenting memory'', the ''amnesiac reaction'', the ''fear of recurrence'' and the individual’s need to cope with both his medical condition and reactions of others to his condition. The recovery phase is treated from the standpoint of unacceptable and acceptable disability. Finally, a recommended psychological treatment for the physician to use in radiation accident cases is made involving the individual's psychological needs, as well as the physician's psychological role which includes: authoritative support, acceptance, optimism, and avoidance of the appearance of an overly scientific approach. Effective organizing, planning or training for the care of radiation accident cases must consider the psychological factors developed. Recommendations for mental health programs which include employee screening and counselling programs are made

Rationale Acute stress produces behavioral and physiological changes modulated by central catecholamines (CA). Stress increases CA activity, and depletion of CA stores reduces responses to stress. Increasing CA activity by administration of the dietary amino acid CA precursor tyrosine may increase responsiveness to stress. This study determined whether tyrosine enhances the ability of humans to respond to severe stress. Methods Severe psychological stress was generated during training at Surv...

Probing gene–environment interactions that affect neural processing is crucial for understanding individual differences in behavior and disease vulnerability. Here, we tested whether the current environmental context, which affects the acute brain state, modulates genotype effects on brain function in humans. We manipulated the context by inducing acute psychological stress, which increases noradrenergic activity, and probed its effect on tonic activity and phasic responses in the amygdala us...
Oxidative stress is an imbalance between cellular production of reactive oxygen species and the counteracting antioxidant mechanisms. The brain with its high oxygen consumption and a lipid-rich environment is considered highly susceptible to oxidative stress or redox imbalances. Therefore, the fact that oxidative stress is implicated in several mental disorders including depression, anxiety disorders, schizophrenia and bipolar disorder, is not surprising.

在现代社会中急慢性心理应激状态颇常见,“思伤脾”是中医的重要理论,基于“急慢性心理应激状态”认识到“思伤脾”理论的“思”是“思障”,并从“思”对胃肠道运动与分泌的影响,“思”对免疫功能的影响,“思”对肠道微环境和微结构的影响,“思”对神经递质含量的影响,“思”与消化系统疾病相关性等方面探讨了“思伤脾”的相关机制,为进一步研究“思伤脾”理论提供参考.%The acute or chronic psychological stress is quite common in the modern society. The theory of anxiety-impairing-spleen is one of the important theories of Traditional Chinese Medicine. According to the theory of acute or chronic psychological stress state, we considered "anxiety" to be "thinking barrier ', thinking about an event for a long time, in the theory of anxiety-impairing-spleen. To explore the pathogenic mechanism of anxiety-impairing-spleen, we reviewed these articles about influence of anxiety on the function of gastrointestinal motility and secretion, on the gut immune function, on the gut microecology and the gut morphology and ultrastructure, on concentration of neurotransmitters, and the correlation between anxiety and gastrointestinal diseases, which may provide the evidence for further pathogenic mechanism research of anxiety-impairing-spleen.

Full Text Available Background: Myopia is a common human vision problem and is increasing in prevalence, yet its etiology remains unclear. A role of psychological stress in the etiology of various ocular disturbances has been suggested, but virtually no research has explored a possible link between psychological stress and myopia development. Methods: In this extension of a recent study, participants (n = 457 who were predominantly undergraduate students completed an anonymous survey assessing both their adult evaluation and retrospective childhood evaluation of their childhood stress. Results: Myopic participants had a significantly higher score on the Stress-Fear-Abuse scale in a factor analysis than did emmetropic participants. Exploratory analyses suggested that myopes in their childhood had lower self-esteem, were more lonely, experienced more criticism about physical aspects of themselves, had higher weight, sat closer to the television, and may have experienced more fear and more very stressful events or situations. Conclusions: Our data suggest that, based on adult evaluations, myopic children have more childhood stress, and based on retrospective childhood evaluations, there is no difference in experience of certain specific childhood stressors. Our data suggest, therefore, that myopic children may have perceptual problems related to recognition and interpretation of stressful situations in their lives. Our findings point to possible unexplored risk factors for myopia and suggest complex interrelationships between psychological stress, childhood emotions, and myopia development in children.

Our prior research has shown that the transcription of endoplasmic reticulum (ER) stress transcription factors activating transcription factor 3 (ATF3) and ATF4 are induced by amphetamine and restraint stress in rat striatum. However, presently the full extent of ER stress responses to psychological stress or cocaine, and which of the three ER stress pathways is activated is unknown. The current study examines transcriptional responses of key ER stress target genes subsequent to psychological stress or cocaine. Rats were subjected to acute or repeated restraint stress or cocaine treatment and mRNA was isolated from dorsal striatum, medial prefrontal cortex and nucleus accumbens brain tissue. ER stress gene mRNA expression was measured using quantitative polymerase chain reaction (PCR) and RNA sequencing. Restraint stress and cocaine-induced transcription of the classic ER stress-induced genes (BIP, CHOP, ATF3 and GADD34) and of two other ER stress components x-box binding protein 1 (XBP1) and ATF6. In addition, rats living in an enriched environment (large group cage with novel toys changed daily) exhibited rapid induction of GADD34 and ATF3 after 30 min of exploring novel toys, suggesting these genes are also involved in normal non-pathological signaling. However, environmental enrichment, a paradigm that produces protective addiction and depression phenotypes in rats, attenuated the rapid induction of ATF3 and GADD34 after restraint stress. These experiments provide a sensitive measure of ER stress and, more importantly, these results offer good evidence of the activation of ER stress mechanisms from psychological stress, cocaine and natural reward. Thus, ER stress genes may be targets for novel therapeutic targets for depression and addiction. PMID:23644055

Psychological stress is an emotion experienced when people are under mental pressure or encounter unexpected problems. Extreme or repetitive stress increases the risk of developing human disease, including cardiovascular disease (CVD), immune diseases, mental disorders, and cancer. Several studies have shown an association between psychological stress and cancer growth and metastasis in animal models and case studies of cancer patients. Stress induces the secretion of stress-related mediators, such as catecholamine, cortisol, and oxytocin, via the activation of the hypothalamic-pituitary-adrenocortical (HPA) axis or the sympathetic nervous system (SNS). These stress-related hormones and neurotransmitters adversely affect stress-induced tumor progression and cancer therapy. Catecholamine is the primary factor that influences tumor progression. It can regulate diverse cellular signaling pathways through adrenergic receptors (ADRs), which are expressed by several types of cancer cells. Activated ADRs enhance the proliferation and invasion abilities of cancer cells, alter cell activity in the tumor microenvironment, and regulate the interaction between cancer and its microenvironment to promote tumor progression. Additionally, other stress mediators, such as glucocorticoids and oxytocin, and their cognate receptors are involved in stress-induced cancer growth and metastasis. Here, we will review how each receptor-mediated signal cascade contributes to tumor initiation and progression and discuss how we can use these molecular mechanisms for cancer therapy. PMID:26916018

The skin is the organ that acts as a barrier between the outer and inner environments of the body. It is thus exposed not only to a wide variety of physical, chemical, and thermal insults from the outside world but also to inner endogenous stimuli. Stress, once an abstract psychologic phenomenon, has taken research's center stage in recent years. The "mind-body connection" is now less of an obscure New Age term and more of an elaborate physiologic pathway by which bilateral communication occurs between body and brain. Dermatologists and dermatologic patients have long acknowledged the effect of stress on the skin and its capability to initiate, maintain, or exacerbate several skin diseases. Because disruption of epidermal barrier integrity may be important in the development of some common skin diseases, it is crucial to understand its vulnerability to psychologic stress. PMID:22507042

Full Text Available BACKGROUND: Results of studies that address the influence of stress on salivary flow rate and composition are controversial. The aim of this study was to reveal the influence of stress vulnerability and different phases of stress reactivity on the unstimulated and stimulated salivary flow rate. We examined that acute mental stress does not change the salivary flow rate. In addition, we also examined the salivary cortisol and protein level in relation to acute mental stress stimuli. METHODS: Saliva of male subjects was collected for five minutes before, immediately, 10, 30 and 120 min after toothbrushing. Before toothbrushing, the subjects were exposed to acute stress in the form of a 2 min public speech. Salivary flow rate and total protein was measured. The physiological stress marker cortisol was analyzed using enzyme-linked immunosorbent assay. To determine the subjects' psychological stress reaction, the State-Trait-Anxiety Inventory State questionnaire (STAI data were obtained. The subjects were divided into stress subgroup (S1 (psychological reactivity, stress subgroup (S2 (psychological and physiological reactivity and a control group. The area under the curve for salivarycortisol concentration and STAI-State scores were calculated. All data underwent statistical analysis using one-way analysis of variance. RESULTS: Immediately after stress exposure, all participants exhibited a psychological stress reaction. Stress exposure did not change the salivary flow rate. Only 69% of the subjects continued to display a physiological stress reaction 20 minutes after the public talk. There was no significant change in the salivary flow rate during the psychological and the physiological stress reaction phases relative to the baseline. CONCLUSIONS: Acute stress has no impact on the salivary flow rate; however, there may be other responses through salivary proteins that are increased with the acute stress stimuli. Future studies are needed to examine

Full Text Available Feelings of ambivalence, melancholy, despair and fear are usual psychological reactions prior to a surgical intervention. Αim: the main aim of this review is a comprehensive presentation of pre-operative anxiety as well as the analysis of the effectiveness of relevant nursing and psychological interventions. A secondary aim was to highlight the role of the nurse in treating pre-operative anxiety. Method: A search in Greek and international databases (IATROTEK, PubMed, CINAHL was conducted. The search strategy combined the following key word: preoperative anxiety, nursing, psychological support. Initially, 123 articles were identified (general articles, clinical studies, reviews, and meta-analysis and after adjustments for duplicate results, the final material of this review were 38 selected articles published during the last decade. Results: Many studies demonstrate the usefulness of preoperative preparation through specialized information and social support interventions in relation to post-surgery adaptation process. The use of methods and strategies that enable the individual to reduce stress and handle the highly-stressing dimensions of the impending surgery have also been proposed. Finally, various psychotherapeutic interventions and other specialized techniques of crisis management as measures to address both the pre-operative anxiety and stress brought about by the disease have also successfully been implemented. Conclusions: The preoperative clinical care must include the systematic treatment of pre-operative anxiety through specialized information. However, behavioral or cognitive interventions that facilitate self-control appear to be more effective and have significant influence on the patient’s postoperative course. Training and education of nurses should be sufficient and part of their continuing education.

Oxidative stress adaptation or hormesis is an important mechanism by which cells and organisms respond to, and cope with, environmental and physiological shifts in the level of oxidative stress. Most studies of oxidative stress adaption have been limited to adaptation induced by acute stress. In contrast, many if not most environmental and physiological stresses are either repeated or chronic. In this study we find that both cultured mammalian cells, and the fruit fly Drosophila melanogaster,...

To assess the self-esteem of pediatric patients on chemotherapy for acute lymphoblastic leukemia (ALL) and psychological status of their parents.The psychological status of 178 children receiving chemotherapy for ALL and their parents was assessed using parenting stress index (PSI) to determine the degree of stress the parents are exposed to using parent's and child's domains. Self-esteem Scale was used to determine the psychological status of patients.The study revealed significant low level of self-esteem in 84.83% of patients. Their parents had significant psychological stress. PSI was significantly associated with parents' low sense of competence, negative attachment to their children, feeling of high restriction, high depression, poor relation to spouse, high social isolation variables of parent's domains. It was significantly associated with low distraction, negative parents' reinforcement, low acceptability, and high demanding variables of child's domains. Long duration of disease was the most detrimental factor among demographic data of the patients.Chemotherapy for ALL has a significant impact on the psychological status of both patients and their parents with high prevalence of low self-esteem in children and high degree of stress in their parents.

Full Text Available Objective: The present study aimed to determine whether castration altered osmotically stimulated vasopressin (VP release and urinary volume and what is the role of endocrine-stress axis in this process.Materials and methods: Totally 108 mice were studied in two main groups of castrated (n=78 and control (n=30. Each group was extracted by acute cold stress (4◦C for 2h/day, restraint stress (by syringes 60cc 2h/day and cold/restraint stress. The castrated group was treated in sub groups of testosterone, control (sesame oil as vehicle of testosterone. Propranolol as blocker of sympathetic nervous system was given to both groups of castrated mice and main control.Results: Our results showed that, there is interactions between testosterone and sympathetic nervous system on vasopressin, because urine volume was decreased only in testoctomized mice with cold/restraint and cold stress (P<0.001; propranolol as the antagonist of sympathetic nervous system could block and increase urine volume in castrated mice. This increased volume of urine was due to acute cold stress, not restraint stress (p<0.001. The role of testosterone, noradrenalin (NA and Vasopressin (VP in the acute cold stress is confirmed, because testosterone could return the effect of decreased urine volume in control group (P<0.001. Conclusion: Considering the effect of cold/restraint stress on urinary volume in castrated mice shows that there is interaction between sex hormone (testosterone, vasopressin and adrenergic systems.

OBJECTIVE: To quantify the available evidence for the hypothesis that reduced resistance caused by psychological stress may influence the development of clinical disease in those exposed to an infectious agent. METHODS: We conducted a systematic review and meta-analysis of 27 prospective studies...... examining the association between psychological stress and subsequent upper respiratory infection (URI). RESULTS: The results revealed a significant overall main effect of psychological stress on the risk of developing URI (effect size correlation coefficient, 0.21; 95% confidence interval, 0.......15-0.27). Further analyses showed that effect sizes for the association did not vary according to type of stress, how URI was assessed, or whether the studies had controlled for preexposure.

Psychological stress is one of the factors associated with human cardiovascular disease. Here, we demonstrate that acute perceived stress impairs the natural capacity of heart regeneration in zebrafish. Beside physical and chemical disturbances, intermittent crowding triggered an increase in cortisol secretion and blocked the replacement of fibrotic tissue with new myocardium. Pharmacological simulation of stress by pulse treatment with dexamethasone/adrenaline reproduced the regeneration failure, while inhibition of the stress response with anxiolytic drugs partially rescued the regenerative process. Impaired heart regeneration in stressed animals was associated with a reduced cardiomyocyte proliferation and with the downregulation of several genes, includingigfbp1b, a modulator of IGF signalling. Notably, daily stress induced a decrease in Igf1r phosphorylation. As cardiomyocyte proliferation was decreased in response to IGF-1 receptor inhibition, we propose that the stress-induced cardiac regenerative failure is partially caused by the attenuation of IGF signalling. These findings indicate that the natural regenerative ability of the zebrafish heart is vulnerable to the systemic paracrine stress response. PMID:27030176

Materials and Methods: A total of 150 students; 75 from 1 st year (2010-2011 and75 from 3 rd year (2009-2010; of medical and paramedical background were assessed on level of MDA (oxidative stress and personality variables, that is, level of anxiety, stress, and depression. These psychological variables were correlated with the level of their oxidative stress. Results: Findings revealed that both groups are influenced by oxidative stress and their psychological variables are also compatible in order to confirm their vulnerabilities to stress. Conclusions: Stress in 3 rd year students was significantly higher and it was noted that it adversely affects the psychological parameters. Hence, special attention on mental health aspect in these students may be given.

The impact of traumatic events is well documented within the clinical psychology literature where it is recognized that people who experience traumatic events may go on to develop posttraumatic stress disorder (PTSD). At first glance one might ask what the relevance of positive psychology is to the study of trauma. But a number of literatures and philosophies throughout human history have conveyed the idea that there is personal gain to be found in suffering. The observation that stressful an...

Full Text Available Abstract Background This study aims to gather information either supporting or rejecting the hypothesis that acute stress may induce ovulation in women. The formulation of this hypothesis is based on 2 facts: 1 estrogen-primed postmenopausal or ovariectomized women display an adrenal-progesterone-induced ovulatory-like luteinizing hormone (LH surge in response to exogenous adrenocorticotropic hormone (ACTH administration; and 2 women display multiple follicular waves during an interovulatory interval, and likely during pregnancy and lactation. Thus, acute stress may induce ovulation in women displaying appropriate serum levels of estradiol and one or more follicles large enough to respond to a non-midcycle LH surge. Methods A literature search using the PubMed database was performed to identify articles up to January 2010 focusing mainly on women as well as on rats and rhesus monkeys as animal models of interaction between the hypothalamic-pituitary-adrenal (HPA and hypothalamic-pituitary-gonadal (HPG axes. Results Whereas the HPA axis exhibits positive responses in practically all phases of the ovarian cycle, acute-stress-induced release of LH is found under relatively high plasma levels of estradiol. However, there are studies suggesting that several types of acute stress may exert different effects on pituitary LH release and the steroid environment may modulate in a different way (inhibiting or stimulating the pattern of response of the HPG axis elicited by acute stressors. Conclusion Women may be induced to ovulate at any point of the menstrual cycle or even during periods of amenorrhea associated with pregnancy and lactation if exposed to an appropriate acute stressor under a right estradiol environment.
Psychogenic fever is a stress-related, psychosomatic disease especially seen in young women. Some patients develop extremely high core body temperature (Tc) (up to 41°C) when they are exposed to emotional events, whereas others show persistent low-grade high Tc (37-38°C) during situations of chronic stress. The mechanism for psychogenic fever is not yet fully understood. However, clinical case reports demonstrate that psychogenic fever is not attenuated by antipyretic drugs, but by psychotropic drugs that display anxiolytic and sedative properties, or by resolving patients' difficulties via natural means or psychotherapy. Animal studies have demonstrated that psychological stress increases Tc via mechanisms distinct from infectious fever (which requires proinflammatory mediators) and that the sympathetic nervous system, particularly β3-adrenoceptor-mediated non-shivering thermogenesis in brown adipose tissue, plays an important role in the development of psychological stress-induced hyperthermia. Acute psychological stress induces a transient, monophasic increase in Tc. In contrast, repeated stress induces anticipatory hyperthermia, reduces diurnal changes in Tc, or slightly increases Tc throughout the day. Chronically stressed animals also display an enhanced hyperthermic response to a novel stress, while past fearful experiences induce conditioned hyperthermia to the fear context. The high Tc that psychogenic fever patients develop may be a complex of these diverse kinds of hyperthermic responses. PMID:27227051

Acute psychological stress (PS) mobilizes metabolic responses that are of immediate benefit to the host, but the current medical paradigm holds that PS exacerbates systemic and cutaneous inflammatory disorders. Although the adverse consequences of PS are usually attributed to neuroimmune mechanisms, PS also stimulates an increase in endogenous glucocorticoids (GCs) that compromises permeability barrier homeostasis, stratum corneum cohesion, wound healing, and epidermal innate immunity in norm...

A limitation of the sport psychology coping literature is the amount of time between a stressful episode and the recall of the coping strategies used in the stressful event (Nicholls & Polman, 2007). The purpose of this study was to develop and implement a technique to measure acute stress and coping during performance. Five high-performance adolescent golfers took part in Level 2 verbalization think aloud trials (Ericsson & Simon, 1993), which involved participants verbalizing their thoughts, over six holes of golf. Verbal reports were audio-recorded during each performance, transcribed verbatim, and analyzed using protocol analysis (Ericsson & Simon, 1993). Stressors and coping strategies varied throughout the six holes, which support the proposition that stress and coping is a dynamic process that changes across phases of the same performance (Lazarus, 1999). The results also revealed information regarding the sequential patterning of stress and coping, suggesting that the golfers experienced up to five stressors before reporting a coping strategy. Think aloud appears a suitable method to collect concurrent stress and coping data. PMID:18612855

Effects of different psychological stimuli on oxytocin (OT) and vasopressin (AVP) secretion are reviewed in animals and in humans. The secretion of neuropituitary hormones is also discussed in various psychiatric diseases such an anorexia nervosa, bipolar disorder, schizophrenia and obsessive-compulsive disorder. AVP and OT are secreted into the hypophyseal portal circulation by neurons which project from the paraventricular nucleus to the external zone of the median eminence. AVP and OT-containing neurons in the suprachiasmatic and paraventricular nuclei project to limbic areas, including the hippocampus, the subiculum, the ventral nucleus of the amygdala and the nucleus of the diagonal band. Specific AVP receptors which are pharmacologically different from the pressor and antidiuretic AVP receptors have been found in the anterior pituitary. OT receptors have been identified in a variety of forebrain sites. The neurohypophyseal secretion is regulated by the cholinergic muscarinic, histaminergic and beta-adrenergic systems. Stress alters the secretion of one or more of the hypothalamic factors which interact at the pituitary to increase the secretion of ACTH. AVP and OT have been shown to modulate the effect of Corticotropin-Releasing Factor (CRF) on ACTH secretion and appear to play a key role in mediating the ACTH response to stress. Although AVP is a relatively weak secretagogue for ACTH, it markedly potentiates the activity of CRF both in vitro and in vivo. The role of OT is more complex. In vitro, OT stimulates ACTH release at high doses whereas in human it inhibits ACTH secretion at low doses. The type of stressor appear to determine the relative importance of these secretatogues in ACTH response. Several recent studies indicate that psychological stressors display a similar degree of variety of secretagogue release patterns as was found earlier for physical stressors. A bewildering array of technique produces a bewildering array of conclusions. In rats, OT

This article reviews the existing evolutionary perspectives on the acute stress response habitual faintness and blood-injection-injury type-specific phobia (BIITS phobia). In this article, an alternative evolutionary perspective, based on recent advances in evolutionary psychology, is proposed. Specifically, that fear-induced faintness (eg, fainting following the sight of a syringe, blood, or following a trivial skin injury) is a distinct Homo sapiens-specific extreme-stress survival response...

Stress and stress hormones are known to influence the function of the hippocampus, a brain structure critical for cognitive-map-based, allocentric spatial navigation. The caudate nucleus, a brain structure critical for stimulus-response-based, egocentric navigation, is not as sensitive to stress. Evidence for this comes from rodent studies, which show that acute stress or stress hormones impair allocentric, but not egocentric navigation. However, there have been few studies investigating the effect of acute stress on human spatial navigation, and the results of these have been equivocal. To date, no study has investigated whether acute stress can shift human navigational strategy selection between allocentric and egocentric navigation. The present study investigated this question by exposing participants to an acute psychological stressor (the Paced Auditory Serial Addition Task, PASAT), before testing navigational strategy selection in the Dual-Strategy Maze, a modified virtual Morris water maze. In the Dual-Strategy maze, participants can chose to navigate using a constellation of extra-maze cues (allocentrically) or using a single cue proximal to the goal platform (egocentrically). Surprisingly, PASAT stress biased participants to solve the maze allocentrically significantly more, rather than less, often. These findings have implications for understanding the effects of acute stress on cognitive function in general, and the function of the hippocampus in particular. PMID:27174311

Psychological stress is an important factor for the development of irritable bowel syndrome (IBS). More and more clinical and experimental evidence showed that IBS is a combination of irritable bowel and irritable brain. In the present review we discuss the potential role of psychological stress in the pathogenesis of IBS and provide comprehensive approaches in clinical treatment. Evidence from clinical and experimental studies showed that psychological stresses have marked impact on intestinal sensitivity, motility, secretion and permeability, and the underlying mechanism has a close correlation with mucosal immune activation, alterations in central nervous system, peripheral neurons and gastrointestinal microbiota. Stress-induced alterations in neuro-endocrine-immune pathways acts on the gut-brain axis and microbiota-gut-brain axis, and cause symptom flare-ups or exaggeration in IBS. IBS is a stress-sensitive disorder, therefore, the treatment of IBS should focus on managing stress and stress-induced responses. Now, non-pharmacological approaches and pharmacological strategies that target on stress-related alterations, such as antidepressants, antipsychotics, miscellaneous agents, 5-HT synthesis inhibitors, selective 5-HT reuptake inhibitors, and specific 5-HT receptor antagonists or agonists have shown a critical role in IBS management. A integrative approach for IBS management is a necessary. PMID:25339801
age-related somatic disorders. The overall aim of the PhD project was to investigate the relation between psychopathology, psychological stress, stress hormone secretion and oxidatively generated DNA and RNA damage, as measured by the urinary excretion of markers of whole-body DNA/RNA oxidation (8......-oxodG and 8-oxoGuo, respectively). The main hypothesis was that psychological stress states are associated with increased DNA/RNA damage from oxidation. In a study of 40 schizophrenia patients and 40 healthy controls matched for age and gender, we found that 8-oxodG/8-oxoGuo excretion was increased in...... schizophrenia patients, providing a possible molecular link between schizophrenia and its associated signs of accelerated aging. We found no association between psychopathology, perceived stress or cortisol secretion and 8-oxodG/8-oxoGuo excretion in the patients. In the controls, there were positive...

Objective: To evaluate the clinical effects of comprehensive therapy of psychological intervention and rehabilitation training on the mental health of the patients with acute stroke. Methods: A total of 120 patients with acute stroke were randomly divided into trial group and control group. Both groups were given the corresponding drug therapy, medical basic nursing and convention nursing. Besides, psychological intervention and comprehensive rehabilitation training were added to the trial group. SCL-90, Europ stroke scales (ESS) score were assessed with each patient on day 3 for the first time and on day 21 for the second time;Barthel index was assessed on the day 90. Results: After psychological intervention, SCL-90 declined significantly in the trial group comparing with the control group, there were signicant differences in the somatization, obsession, depression, anxiety, fear, ESS score, Barthel index and other psychological factors between the trial group and control group (P<0.05). Conclusions:Comprehensive therapy of early psychological intervention and rehabilitation training can significantly improve the mental health, limb movement function, stress ability and activity of daily living on the patients with acute stroke.
Full Text Available We report study results of personality characteristics as predictors of positive states (active, optimistic, emotional, subjective comfort and stress experience in adults with one higher education and ongoing training in Psychology. The respondents were 107 people aged 23 to 52 years. Diagnostic methods we used were: "SMIL" (L. Sobchik, Optimism and Activity Scale (adapted by E. Vodopyanova, C. Izard Differential Emotions Scale (adapted by A. Leonova, Subjective Comfort Scale (adapted by A. Leonova, PSM-25 Scale by Lemyr-Tessier-Fillion. The regression analysis revealed that in subjects ongoing training in Psychology, basic predictor of positive emotions and stress experience is anxiety. Cluster analysis revealed three types of subjects by their positive states experiences, which differ primarily by the level of baseline anxiety and related personality characteristics. The group of risk comprised Psychology students with a tendency to depression and negative emotions and specific personality profile.

Dried rhizomes of Cimicifuga racemosa (CR), which are known as black cohosh, have been widely used as herbal dietary supplements to treat menopausal symptoms. The present study examined the effect of CR extracts on human psychological and physiological responses to acute stress induced by mental arithmetic tests, by measuring the subjective stress intensity, the brain-wave patterns according to electroencephalography, and the concentrations of salivary chromogranin-A and cortisol. The experiments were performed double-blind and their order was counterbalanced. Treatment with CR significantly attenuated the elevated subjective perception of stress and the increased salivary chromogranin-A levels compared with placebo treatment. CR extract also rapidly recovered the decrease in alpha waveband induced by performing the mental arithmetic task. We therefore propose that CR extracts might be suitable for the prevention and treatment of stress-related disorders. PMID:22790213

Recent investigations have suggested that stress can modulate motor function. However, the impact of stress on motor performance of musicians suffering from focal dystonia (FDM) remains unknown. The current study assessed motor performance in 20 FDM patients and 16 healthy musicians (HM) before and under stress. Stress was manipulated using the Trier Social Stress Test (TSST). Motor performance was evaluated based on analysis of electromyographic (EMG) activity and temporal variability, while electrocardiography (ECG) and the level of free cortisol were used to test for objective alterations of the hypothalamic-pituitary-adrenal (HPA) axis. Finally, the psychological profiles of both groups were analyzed using three psycho-diagnostic standardized questionnaires. Results showed that patients' motor impairments did not change under acute stressful conditions. However, an increase in muscular co-contractions was observed, reflecting a physiological muscular response under stressful conditions. Psycho-diagnostic analysis revealed higher levels of psychological traits related to elevated anxiety, stress and perfectionism in 40% of the patients. Although the motor outcome between those patients and those with an opposing psychological profile did not differ, patients characterized by stressful and perfectionistic personalities had, on average, developed dystonia about ten years earlier than the rest of the patients. The current study suggests that acute stress conditions may not have any direct impact on fine motor control of FDM patients. However psychological traits associated with increased stress, anxiety and perfectionism may have a long-lasting effect on the motor function of affected musicians, by promoting the acceleration or even the triggering of dystonia.

Obesity may contribute to cardiovascular disease (CVD) risk by eliciting chronic systemic inflammation and impairing the immune response to additional stressors. There has been little assessment of the effect of obesity on psychological stress, an independent risk factor for CVD. Therefore, it was of interest to examine interleukin-6, tumor necrosis factor-α, interleukin-1β (IL-1β), interleukin-1 receptor antagonist (IL-1Ra), and leptin following an acute mental stress task in nonobese and obese males. Twenty college-aged males (21.3 ± 0.56 years) volunteered to participate in a 20-min Stroop color-word and mirror-tracing task. Subjects were recruited for obese (body mass index: BMI > 30) and nonobese (BMI < 25) groups, and blood samples were collected for enzyme-linked immunosorbent assay analysis. The acute mental stress task elicited an increase in heart rate, catecholamines, and IL-1β in all subjects. Additionally, acute mental stress increased cortisol concentrations in the nonobese group. There was a significant reduction in leptin in obese subjects 30 min posttask compared with a decrease in nonobese subjects 120 min posttask. Interestingly, the relationship between the percent change in leptin and IL-1Ra at 120 min posttask in response to an acute mental stress task was only observed in nonobese individuals. This is the first study to suggest that adiposity in males may impact leptin and inflammatory signaling mechanisms following acute mental stress. PMID:26511907

AIM: To evaluate gastric motility using electrical bio-impedance (EBI) and gastric changes as a result of stress induced by psychological tests. METHODS: A group of 57 healthy women, aged 40-60 years, was recruited, and a clinical history and physical examination were performed. The women were free from severe anxiety, chronic or acute stress, severe depression, mental diseases and conditions that affect gastric activity. The women were evaluated under fasting conditions, and using a four-electrode configuration, the gastric signals were obtained through a BIOPAC MP-150 system. The volunteers were evaluated using the following paradigm: basal state, recording during the Stroop Test, intermediate resting period, recording during the Raven Test, and a final resting period. We analyzed the relative areas of the frequency spectrum: A1 (1-2 cpm), A2 (2-4 cpm), A3 (4-8 cpm), and A4 (8-12 cpm), as well as the median of area A2 + A3. The data were analyzed by an autoregressive method using a Butterworth filter with MatLab and Origin. Analysis of variance (ANOVA) and Friedman ANOVA (for nonparametric variables) were performed; in addition, pairs of groups were compared using the T dependent and Wilcoxon T tests. RESULTS: The results of the main values of area A2 were not significantly different comparing the five steps of the experimental paradigm. Nevertheless, there was a tendency of this A2 region to decrease during the stress tests, with recuperation at the final resting step. When an extended gastric region was considered (1-4 cpm), significant differences with the psychological stress tests were present (F = 3.85, P = 0.005). The A3 region also showed significant changes when the stress psychological tests were administered (F = 7.25, P < 0.001). These differences were influenced by the changes in the adjacent gastric region of A2. The parameter that we proposed in previous studies for the evaluation of gastric motility by electrical bio-impedance (EBI) was the median

Assessments of acute stress using self-report questionnaires can be biased by various factors, including social desirability. The present study used a bias-free method, the Implicit Association Test (IAT), to assess stress. Unlike a previous study (Schmukle & Egloff, 2004) in which acute stress was not detected with the IAT, this study manipulated stress by generating test anxiety and threatening self-esteem. The results revealed that the IAT effect was greater in the high-stress group than in the low-stress group. Participants in the high-stress group associated their concept of self with the concept of anxiety more strongly than did those in the low-stress group. This result suggests that the IAT is a sensitive measure for detecting group differences in acute stress. PMID:21432650
Full Text Available The impact of traumatic events is well documented within the clinical psychology literature where it is recognized that people who experience traumatic events may go on to develop posttraumatic stress disorder (PTSD. At first glance one might ask what the relevance of positive psychology is to the study of trauma. But a number of literatures and philosophies throughout human history have conveyed the idea that there is personal gain to be found in suffering. The observation that stressful and traumatic events can provoke positive psychological changes is also contained in the major religions of Buddhism, Christianity, Hinduism, Islam, and Judaism. Within existential philosophy and humanistic psychology it has also been recognized that positive changes can come about as a result of suffering. But it is only within the last decade that the topic of growth following adversity has become a focus for empirical work. In this paper I will provide an overview of the subject and the research we have conducted at the Centre for Trauma, Resilience, and Growth (CTRG.

BACKGROUND: Psychological stress negatively influences food intake and food choices, thereby contributing to the development of childhood obesity. Physical activity can also moderate eating behavior and influence calorie intake. However, it is unknown if acute physical activity influences food intake and overall energy balance after acute stress exposure in children. We therefore investigated the impact of acute physical activity on overall energy balance (food intake minus energy expenditure...

Posttraumatic stress disorder (PTSD) has only relatively recently been introduced into the diagnostic classification of mental disorders. Building on advances in the treatment of other anxiety disorders, a range of effective psychological treatments for PTSD has been developed. The most effective of these treatments focus on the patient’s memory for the traumatic event and its meaning. This paper briefly reviews the currently available evidence for these treatments. It then illustrates the pr...

The treatment of pathologic aerophagia has rarely been discussed in the literature. In this retrospective study, the authors investigated the effects of clonazepam on the management of pathologic childhood aerophagia (PCA) with psychological stresses (PS), but not with mental retardation. Data from 22 consecutive PCA patients with PS (aged 2 to 10 yr), who had been followed up for over 1 yr, were reviewed. On the basis of videolaryngoscopic views, the authors observed that the pathologyof aer...
We test if brief physical exercise can reduce cardiovascular arousal not just during a psychological stressor, as prior studies suggest, but both before it occurs, when one is anticipating the stressor, and after it occurs, when one is ruminating about it. Including both anticipatory and recovery responses may be more consistent with how individuals use exercise to cope with stress. It is also relevant to an expanded view of the cardiovascular reactivity hypothesis, which suggests that the du...

Full Text Available INTRODUCTION Psychological stress is part of people's lives and can sometimes contribute to exacerbation of allergic diseases such as asthma. Asthma is prevalent in all age groups. Acute asthma attacks can be triggered by stress, thus impacting control of the disease and overall quality of life in these patients. OBJECTIVE The purpose of this study is to evaluate the presence of psychological stress as a trigger in poorly controlled asthma patients and its implications in their quality of life. METHODS A descriptive study was conducted in the city of Manzanillo, Cuba, in the course of one year, from January to December, 2010, which included 33 patients with persistent asthma. They were grouped according to severity as suffering from moderate or severe asthma, and all of them met the criteria for poorly controlled disease. They were surveyed to gather data about family and personal history of atopy, age of first asthma crisis, and environmental as well as other factors. Two surveys were used: a list of indicators of vulnerability to stress and the Asthma Quality of Life Questionnaire (AQLQ. RESULTS Most patients with poorly controlled asthma were in their forties. Female patients were more frequently affected than men were (28 females or 84.8%, and 5 males or 15.1%, and most patients had a family history of atopic disease. Almost all patients had high vulnerability to stress as well as low overall quality of life in all the areas surveyed. CONCLUSION Psychological counseling is advised for asthma patients in order to reduce their stress levels.

The term "psychological stress" describes a situation in which a subject perceives that environmental demands tax or exceed his or her adaptive capacity. According to the Cochrane Database of Systematic Reviews, the best validated approach covering both stress management and stress treatment is the Cognitive Behavioral (CBT) approach. We aim to design, develop and test an advanced ICT based solution for the assessment and treatment of psychological stress that is able to improve the actual CBT approach. To reach this goal we will use the "interreality" paradigm integrating assessment and treatment within a hybrid environment, that creates a bridge between the physical and virtual worlds. Our claim is that bridging virtual experiences (fully controlled by the therapist, used to learn coping skills and emotional regulation) with real experiences (allowing both the identification of any critical stressors and the assessment of what has been learned) using advanced technologies (virtual worlds, advanced sensors and PDA/mobile phones) is the best way to address the above limitations. To illustrate the proposed concept, a clinical scenario is also presented and discussed: Paola, a 45 years old nurse, with a mother affected by progressive senile dementia. PMID:20543263

As humans continue to explore and expand in the solar system, psychological problems brought about by high stress of living in the space environment will continue to increase. Unfortunately, due to many reasons, including relative difficulties with gaining access to astronauts and cosmonauts and to gather psychological data from them regarding stressors, this area is not very well known and discussed. Five astronauts and cosmonauts from three space agencies: ESA, RSA, and JAXA were unoffi- cially surveyed regarding their experiences with ten general categories of psychological stressors as well as eight subcategories of interpersonal conflict stressors accepted in space related community of psychologists. The two subjects in space for longer periods of time reported more stressors and were likely to rate stressors as having a greater effect on the chance of mission failure. Shorter duration flyers reported nearly all general stressors were likely to increase in the event of a longer duration space flight. With the increased interest in long duration spaceflight, psychological stressors are more likely to affect mission success.

Plaque rupture,platelet aggregation,and thrombogenesis are the main mechanisms of acute coronary syndrome (ACS),and inflammation factors play key roles in plaque unstability.Psychological stress promotes acute inflammatory response,leading to increased circulating levels of C-reactive protein (CRP),IL-6,and serum intercellular adhesion molecule (sICAM)-1.But it is not clear that whether psychological stress has a direct effect on atherosclerotic plaque stability.The purpose of this study was to investigate effects of chronic psychological stress on inflammatory marker (ICAM-1 ) in atherosclerotic plaque,and inflammatory markers in peripheral blood.Materials and methods Sixty male rabbits were randomized into 2 groups:the control group (n =10) and the atherosclerotic group (n =50).The latter were fed on high fatty diet and were given a large dose of vitamin D3 (3 600 000IU/kg) via intraperitoneal injection.After 8 weeks,the atherosclerotic model was estaslished.Then the 50 atherosclerotic model rabbits were divided into 3 subgroups:no-stress subgroup (n = 16),physiological stress subgroup (n = 16) and psychological stress subgroup (n =18).In physiological stress subgroup and psychological stress subgroup,drinking was cut from twice a day to once a day.At the same time,psychological stress subgroup was given empty bottle stress,and this process lasted for 2 weeks.One hour after the last stress,the blood samples were collected and the serum levels of CRP,IL-6 amd ICAM-1 were tested by radioimmunoassay or enzyme linked immunosorbent assay.The aorta and heart were extracted for pathology examination,and the express of ICAM-1 was tested by immunohistochemical examination.Results (1) After effective atherosclerotic animal model construction,the expression of ICAM-1 in aorta was higher in atherosclerotic group than that in control group (P＜0.01),and was notably higher in psychological stress subgroup than that in no-stress subgroup or in physiological stress subgroup (2

Objective To summarize current understanding of the roles of anti-inflammatory and proinflammatory mechanisms in the development of atherosclerosis and acute coronary syndrome and to postulate the novel concept of inflammation stress as the most important factor triggering acute coronary syndrome. Moreover, markers of inflammation stress and ways to block involved pathways are elucidated.Data sources A literature search (MEDLINE 1997 to 2002) was performed using the key words "inflammation and cardiovascular disease". Relevant book chapters were also reviewed.Study selection Well-controlled, prospective landmark studies and review articles on inflammation and acute coronary syndrome were selected.Data extraction Data and conclusions from the selected articles providing solid evidence to elucidate the mechanisms of inflammation and acute coronary syndrome were extracted and interpreted in the light of our own clinical and basic research.Data synthesis Inflammation is closely linked to atherosclerosis and acute coronary syndrome. Chronic and long-lasting inflammation stress, present both systemically or in the vascular walls, can trigger acute coronary syndrome.Conclusions Inflammation stress plays an important role in the process of acute coronary syndrome. Drugs which can modulate the balance of pro- and anti-inflammatory processes and attenuate inflammation stress, such as angiotensin-converting enzyme (ACE) inhibitors/angiotensin Ⅱ receptor blockers, statins, and cytokine antagonists may play active roles in the prevention and treatment of acute coronary syndrome when used in addition to conventional therapies (glycoprotein Ⅱb/Ⅲa receptor antagonists, mechanical intervention strategies, etc).

This paper examines before and after perceived stress scores (PSS) of Hispanic women participating in a brief community health promotion program. Scores declined dramatically and significantly after the intervention, approximating those of Hispanics nationally. Post PSS were significantly correlated with language preference (Spanish), educational level, employment, having gone to jail or been in detention, and income. In the regression model, language preference and income were significant. We suggest emotional fear at the onset of participation in the program may exert an influence on pre-PSS scores, and that increased familiarity/rapport with program staff and having social psychological needs met may ameliorate this fear. Preference for Spanish, the language spoken at home for the majority of participants, may indicate a resistance to acculturating to mainstream culture, and, consequently, create a buffer against perceived stress.

Full Text Available The management of depression and other negative psychological states in cardiac patients has been a focus of multiple treatment trials, though such trials have not led to substantial improvements in cardiac outcomes. In contrast, there has been minimal focus on interventions to increase positive psychological states in cardiac patients, despite the fact that optimism and other positive states have been associated with superior cardiovascular outcomes. Our objective was to develop an 8-week, phone-based positive psychology intervention for patients hospitalized with acute cardiac disease (acute coronary syndrome or decompensated heart failure. Such an intervention would consist of positive psychology exercises adapted for this specific population, and it would need to be feasible for practitioners and patients in real-world settings. By adapting exercises that were previously validated in healthy individuals, we were able to generate a positive psychology telemedicine intervention for cardiac patients that focused on optimism, kindness, and gratitude. In addition, we successfully created a companion treatment manual for subjects to enhance the educational aspects of the intervention and facilitate completion of exercises. Finally, we successfully performed a small pilot trial of this intervention, and found that the positive psychology intervention appeared to be feasible and well-accepted in a cohort of patients with acute cardiac illness. Future studies should further develop this promising intervention and examine its impact on psychological and medical outcomes in this vulnerable population of cardiac patients.
Full Text Available Abstract Background Having a child hospitalized is a stressful event for parents. Previous studies have found increased stress in families with children affected by different kinds of pathologies, and analyzed disease related objective variables producing stress. However, most of these studies recruited caregivers of children with chronic or serious illnesses, and focused on evaluation of objective environmental stressors and did not consider subjective "perception" of stress. The aim of this study was to investigate perception of acute stress in caregivers taking care of children without serious physical damage that were hospitalized for short periods. Moreover, some variables, such as recreational and school services offered to children, influencing perception of cognitive, physiological and behavioral state relating to the sensation of "being stressed" were analyzed. Methods This study was realized with a sample of caregivers of children hospitalized for mild acute diseases. Research was conducted using two standardized tests, PSM (Psychological Stress Measure and STAI (State Trait Anxiety Inventory, whose characteristics of reliability and validity had been successfully established. Results Present data showed that caregivers of hospitalized children perceived high levels of stress and anxiety. Perception of stress was influenced by the degree of kindred with patients, length of hospitalization, and, notably, participation in some of the activities offered to children, mainly school services. Discussion Findings showed that child hospitalization is a stressful event for caregivers, even if hospitalization is for middle and transient pathologies. Perception of stress was influenced by length of hospitalization, and by degree of kindred. Findings even suggest that some services offered to children can modulate caregivers' perception of stress and impact of hospitalization. Caregivers whose children used school services describe themselves as
Full Text Available BACKGROUND and AIMS: Mental stress is considered to be a precipitating factor in acute coronary events. We aimed to assess the association of subjective or 'perceived' mental stress with the occurrence of acute coronary events. SETTINGS AND DESIGN: Prospective case-control survey was carried out in a referral teaching hospital. subjects & METHODS: Consecutive patients with acute myocardial infarction and ST elevation on electrocardiogram who were admitted to the Coronary Care Unit of a referral teaching hospital were enrolled in the study as cases. Controls were unmatched and were enrolled from amongst patients with coronary artery disease who did not have recent acute coronary events. Subjective Stress Functional Classification (SS-FC for the preceding 2-4 weeks was assessed and assigned four grades from I to IV as follows: I - baseline, II - more than usual but not affecting daily routine, III - significantly high stress affecting daily routine and IV - worst stress in life. STATISTICAL ANALYSIS: Proportions of different characteristics were compared using chi-square test with Yates continuity correction. Student's unpaired t test was applied for mean age. 'p' value of < 0.05 was considered statistically significant. RESULTS: SS-FC could be reliably (99% and easily assessed. Eighty (53% of the total 150 patients with acute MI reported 'high' levels of stress (stress class III and IV. This is in contrast to only 30 (20% of 150 healthy controls reporting high stress for the same period (p value < 0.001. CONCLUSION: Patients with acute myocardial infarction report a higher subjective mental stress during 2 to 4 weeks preceding the acute coronary event.

It has been previously shown that the implicit affiliation motive - the need to establish and maintain friendly relationships with others - leads to chronic health benefits. The underlying assumption for the present research was that the implicit affiliation motive also moderates the salivary cortisol response to acute psychological stress when some aspects of social evaluation and uncontrollability are involved. By contrast we did not expect similar effects in response to exercise as a physical stressor. Fifty-nine high school students aged M=14.8 years were randomly assigned to a psychosocial stress (publishing the results of an intelligence test performed), a physical stress (exercise intensity of 65-75% of HRmax), and a control condition (normal school lesson) each lasting 15min. Participants' affiliation motives were assessed using the Operant Motive Test and salivary cortisol samples were taken pre and post stressor. We found that the strength of the affiliation motive negatively predicted cortisol reactions to acute psychosocial but not to physical stress when compared to a control group. The results suggest that the affiliation motive buffers the effect of acute psychosocial stress on the HPA axis. PMID:25016451

Most authorities agree that mass disasters leave in their wake a need for some form of acute mental health services. However, a review of current literature on crisis intervention and disaster mental health reveals differing points of view on the methods that should be employed (Raphael, 1986; NIMH, 2002). Nevertheless, there appears to be virtual universal endorsement, by relevant authorities, of the value of acute "psychological first aid" (American Psychiatric Association, 1954; USDHHS, 2004; Raphael, 1986; NIMH, 2002; Institute of Medicine, 2003; WHO, 2003; DoD/VAPTSD, 2004; Ritchie, et al., 2004; Friedman, Hamblin, Foa, & Charney, 2004). Psychological first aid (PFA), as an acute mental health intervention, seems uniquely applicable to public health settings, the workplace, the military, mass disaster venues, and even the demands of more well circumscribed critical incidents, e.g., dealing with the psychological aftermath of accidents, robberies, suicide, homicide, or community violence. In this document, we shall introduce the notion of psychological first aid (PFA) as one aspect of a psychological continuum of care, offer a rudimentary definition of PFA, and provide the reader with a practicalframework for its implementation utilizing the individual psychological first aid (iPFA)format. The goal of this paper is to better prepare public health, public safety, and other disaster response personnel who do not possess formal clinical mental health degrees or specialized training to provide iPFA services to primary and secondary disaster victims.

A study is summarized which demonstrates that depletion of the biogenic amines 5-hydroxytryptamine (5-HT) or norepinephrine (NE) alters the normal thermoregulatory responses to acute temperature stress. Specifically, NE depletion caused a significant depression in equilibrium rectal temperature at 22 C and a greater depression in rectal temperature than controls in response to cold (6 C) stress; NE depletion also resulted in a significantly higher rectal temperature response to acute heat (38 C) stress. Depletion of 5-HT had less severe effects. It remains unclear whether the primary site of action of these agents is central or peripheral.
Full Text Available Stress is one of the most important health and social problems. Previous studies have demonstrated stress influence on the clinical course of a number of gastrointestinal diseases, but its physical and psychological effects on gastric acid and pepsin secretions are largely unknown. 48 male wistar rats weighing 200-250 gr were used in this study. Animals were divided into 6 groups (n=8; Control, Physical stress, Psychological stress, L-NAME+ Physical stress and L-NAME+ Psychological stress groups. In this study, electrical shock generated in a communication box was used as physical shock and the emotional stress was as psychological stress.Gastric juice was collected by washout technique. Acid output was also measured by digital titrator. Gastric pepsin and nitric oxide (NO metabolites were quantified using Anson and Griess micro assay methods respectively.Basal and stimulated gastric acid and pepsin in physical and psychological stress groups were significantly more than others. NO metabolites level of gastric tissue in physical and psychological stress groups (286.9 ± 5.8, 287.7 ± 5.7 μmol/gr weight wet tissue, respectively were significantly more than other groups. But no significant differences among basal and stimulated gastric acid, pepsin and NO metabolites level were seen in physical and psychological stress groups.

Background Most data about psychological factors relating to acute myocardial infarction (AMI) were obtained from studies carried out in western countries. Results from small descriptive cross-sectional studies in China were inconclusive. The aim of this study was to explore possible associations between psychological risk factors and AMI among the Chinese population with a large-scale case-control study.Methods This study was part of the INTER-HEART China study, itself part of the large international INTER-HEART study of cardiovascular risk factors. In this case-control study, 2909 cases and 2947 controls were recruited from 17 cities.Psychological stress, negative life events, depression and controllability of life circumstances were assessed.Results Cases reported more psychological stress at home or work and odds ratios (ORs) were 3.2 (95% CI 2.1-4.9)for permanent stress and 2.1 (95% CI 1.5-2.8) for several periods of stress respectively. More cases experienced depression compared with controls (19.6% vs. 9.3%) and ORs were 2.2 (95% CI 1.9-2.6). Subjects with 1, 2 and 3 or more depressive symptoms had increased risk of AMI by 2.1, 2.2 and 2.6 fold, respectively, i.e., more depressive symptoms were associated with higher risks of AMI (P for trend ＜0.0001). Women had a greater risk of AMI from depression (OR 3.0, 95% CI 2.2-4.0) compared to men (OR 2.0, 95% CI 1.6-2.4), P for interaction =0.0364. Negative life events in subjects were associated with increased risk of AMI, OR 1.7 (95% CI 1.4-2.0) for one event and 1.8 (95% CI 1.3-2.4) for two or more events. High levels of controllability of life circumstances reduced the risk for AMI (OR 0.8, 95%CI 0.7-1 .0).Conclusions Several psychological factors were closely associated with increased AMI risk among Chinese population.Psychological stress had a greater AMI risk in men but depression was more significant among women.

Background: Stress, one of the strongest risk factors for depression, has been linked to "anbedonic" behavior and dysfunctional reward-related neural circuitry in preclinical models. Methods: To test if acute stress reduces reward responsiveness (i.e., the ability to modulate behavior as a function of past reward), a signal-detection task coupled with a differential reinforcement schedule was utilized. Eighty female participants completed the task under both a stress condition, either threat-...

AIM:To evaluate gastric motility using electrical bioimpedance (EBI) and gastric changes as a result of stress induced by psychological tests.METHODS:A group of 57 healthy women,aged 40-60years,was recruited,and a clinical history and physical examination were performed.The women were free from severe anxiety,chronic or acute stress,severe depression,mental diseases and conditions that affect gastric activity.The women were evaluated under fasting conditions,and using a four-electrode configuration,the gastric signals were obtained through a BIOPAC MP-150system.The volunteers were evaluated using the following paradigm:basal state,recording during the Stroop Test,intermediate resting period,recording during the Raven Test,and a final resting period.We analyzed the relative areas of the frequency spectrum:A1 (1-2 cpm),A2 (2-4 cpm),A3 (4-8 cpm),and A4 (8-12 cpm),as well as the median of area A2 + A3.The data were analyzed by an autoregressive method using a Butterworth filter with MatLab and Origin.Analysis of variance (ANOVA)and Friedman ANOVA (for nonparametric variables) were performed; in addition,pairs of groups were compared using the Tdependent and Wilcoxon Ttests.RESULTS:The results of the main values of area A2 were not significantly different comparing the five steps of the experimental paradigm.Nevertheless,there was a tendency of this A2 region to decrease during the stress tests,with recuperation at the final resting step.When an extended gastric region was considered (1-4cpm),significant differences with the psychological stress tests were present (F =3.85,P =0.005).The A3 region also showed significant changes when the stress psychological tests were administered (F =7.25,P ＜0.001).These differences were influenced by the changes in the adjacent gastric region of A2.The parameter that we proposed in previous studies for the evaluation of gastric motility by electrical bio-impedance (EBI)was the median of the area under the region from 2 to 8 cpm (A2

Research suggests that police work is among the most stressful occupations in the world and officers typically suffer a variety of physiological, psychological, and behavioral effects and symptoms. Officers operating under severe or chronic stress are likely to be at greater risk of error, accidents, and overreactions that can compromise their performance, jeopardize public safety, and pose significant liability costs to the organization. Therefore, this study explored the nature and degree of physiological activation typically experienced of officers on the job and the impact of the Coherence Advantage resilience and performance enhancement training on a group of police officers from Santa Clara County, California. Areas assessed included vitality, emotional well-being, stress coping and interpersonal skills, work performance, workplace effectiveness and climate, family relationships, and physiological recalibration following acute stressors. Physiological measurements were obtained to determine the real-time cardiovascular impact of acutely stressful situations encountered in highly realistic simulated police calls used in police training and to identify officers at increased risk of future health challenges. The resilience-building training improved officers' capacity to recognize and self-regulate their responses to stressors in both work and personal contexts. Officers experienced reductions in stress, negative emotions, depression, and increased peacefulness and vitality as compared to a control group. Improvements in family relationships, more effective communication and cooperation within work teams, and enhanced work performance also were noted. Heart rate and blood pressure measurements taken during simulated police call scenarios showed that acutely stressful circumstances typically encountered on the job result in a tremendous degree of physiological activation, from which it takes a considerable amount of time to recover.

Risk perceptions are only slightly correlated with the expected values of a probability distribution for negative health impacts. Psychometric studies have documented that context variables such as dread or personal control are important predictors for the perceived seriousness of risk. Studies about cultural patterns of risk perceptions emphasize different response set to risk information, depending on cultural priorities such as social justice versus personal freedom. This chapter reports the major psychological research pertaining to the factors that govern individual risk perception and discusses the psychometric effects due to people's risk perception and the experience of severe stress. The relative importance of the psychometric content variables, the signals pertaining to each health risks and symbolic beliefs are explained. (Author)

Stress interferes with instrumental learning. However, choice is also influenced by non-instrumental factors, most strikingly by biases arising from Pavlovian associations that facilitate action in pursuit of rewards and inaction in the face of punishment. Whether stress impacts on instrumental learning via these Pavlovian associations is unknown. Here, in a task where valence (reward or punishment) and action (go or no-go) were orthogonalised, we asked whether the impact of stress on learning was action or valence specific. We exposed 60 human participants either to stress (socially-evaluated cold pressor test) or a control condition (room temperature water). We contrasted two hypotheses: that stress would lead to a non-selective increase in the expression of Pavlovian biases; or that stress, as an aversive state, might specifically impact action production due to the Pavlovian linkage between inaction and aversive states. We found support for the second of these hypotheses. Stress specifically impaired learning to produce an action, irrespective of the valence of the outcome, an effect consistent with a Pavlovian linkage between punishment and inaction. This deficit in action-learning was also reflected in pupillary responses; stressed individuals showed attenuated pupillary responses to action, hinting at a noradrenergic contribution to impaired action-learning under stress.

Full Text Available Delay discounting refers to the reduction of the value of a future reward as the delay to that reward increases. The rate at which individuals discount future rewards varies as a function of both individual and contextual differences, and high delay discounting rates have been linked with problematic behaviors, including drug abuse and gambling. The current study investigated the effects of acute anticipatory stress on delay discounting, while considering two important factors: individual perceptions of stress and whether the stressful situation is future-focused or present-focused. Half of the participants experienced acute stress by anticipating giving a videotaped speech. This stress was either future-oriented (speech about future job or present-oriented (speech about physical appearance. They then performed a delay discounting task, in which they chose between smaller, immediate rewards and larger, delayed rewards. Their scores on the Perceived Stress Scale were also collected. The way in which one appraises a stressful situation interacts with acute stress to influence choices; under stressful conditions, delay discounting rate was highest in individuals with low perceived stress and lowest for individuals with high perceived stress. This result might be related to individual variation in reward responsiveness under stress. Furthermore, the time orientation of the task interacted with its stressfulness to affect the individual’s propensity to choose immediate rewards. These findings add to our understanding of the intermediary factors between stress and decision making.
Full Text Available This paper presents an empirical investigation on the effects of occupational stress, psychological stress as well as job burnout on women’s employee performance in city of Karaj, Iran. The proposed study designs a questionnaire in Likert scale and distributes it among all female employees who worked for Bank Maskan in this city. In our survey, employee performance consists of three parts of interpersonal performance, job performance as well as organizational performance. Cronbach alpha has been used to verify the overall questionnaire, all components were within acceptable levels, and the implementation of Kolmogorov-Smirnov test has indicated that the data were not normally distributed. Using Spearman correlation ratio as well as regression techniques, the study has determined that while psychological stress influenced significantly on all three components of employee performance including interpersonal performance, job performance as well as organizational performance, the effect on job performance was greater than the other components. In addition, occupational stress only influences on organizational as well as interpersonal performance. Finally, employee burnout has no impact on any components of employee performance.

The effects of stress are frequently studied, yet its proximal causes remain unclear. Here we demonstrate that subjective estimates of uncertainty predict the dynamics of subjective and physiological stress responses. Subjects learned a probabilistic mapping between visual stimuli and electric shocks. Salivary cortisol confirmed that our stressor elicited changes in endocrine activity. Using a hierarchical Bayesian learning model, we quantified the relationship between the different forms of subjective task uncertainty and acute stress responses. Subjective stress, pupil diameter and skin conductance all tracked the evolution of irreducible uncertainty. We observed a coupling between emotional and somatic state, with subjective and physiological tuning to uncertainty tightly correlated. Furthermore, the uncertainty tuning of subjective and physiological stress predicted individual task performance, consistent with an adaptive role for stress in learning under uncertain threat. Our finding that stress responses are tuned to environmental uncertainty provides new insight into their generation and likely adaptive function. PMID:27020312

A critical job event (CJE) is defined as a time-bounded peak of performance demand made on the individual as an integral part of his job. Though such events are an important source of acute job stress and are amenable to longitudinal study, relevant research has been scant. In the present study, the effects of acute objective stress on subjective stress and on psychological and physiological strain were assessed among 39 first-year nursing students in an interrupted time series with multiple replications. Strain was measured five times, twice in anticipation of CJE interspersed by three low-stress occasions. The CJEs were providing the first comprehensive patient care and the final exam in nursing. A consistently confirmatory pattern of significantly rising and falling strain was found for anxiety, systolic blood pressure, and pulse rate: qualitative overload and serum uric acid changed as predicted four times out of five. CJE research can redress past overemphasis on chronic organizational stress and strengthen causal interpretation. PMID:10257633

Full Text Available Tsukasa Kato Department of Social Psychology, Toyo University, Tokyo, Japan Abstract: Hospital nurses frequently experience relationships with patients as stressors in the workplace. Nurses’ coping behavior is one potential buffering factor that can reduce the effects of job stress on their psychological functioning and well-being. In this study, the association between nurses' strategies for coping with interpersonal stress from patients and their psychological distress was examined. Participants included 204 hospital nurses and 142 salespeople, who were used as a comparison group. Participants completed measures of coping with interpersonal stress and psychological distress. Hospital nurses reported more psychological distress than did salespeople. Moreover, distancing coping was correlated with high psychological distress in both nurses and salespeople, and reassessing coping was correlated with low psychological distress in nurses. For nurses only, constructive coping appeared to be an effective strategy for reducing psychological distress. It is important for nurses to understand the role of constructive coping in nurse–patient communication and interaction.

Full Text Available Acute stress induced alterations in the activity levels of rate limiting enzymes and concentration of intermediates of different pathways of carbohydrate metabolism have been studied. Adult male Wistar rats were restrained (RS for 1 h and after an interval of 4 h they were subjected to forced swimming (FS exercise and appropriate controls were maintained. Five rats were killed before the commencement of the experiment (initial controls, 5 control and equal number of stressed rats were killed 2 h after RS and remaining 5 rats in each group were killed 4 h after FS. There was a significant increase in the adrenal 3β- hydroxy steroid dehydrogenase activity following RS, which showed further increase after FS compared to controls and thereby indicated stress response of rats. There was a significant increase in the blood glucose levels following RS which showed further increase and reached hyperglycemic condition after FS. The hyperglycemic condition due to stress was accompanied by significant increases in the activities of glutamate- pyruvate transaminase, glutamate- oxaloacetate transaminase, glucose -6- phosphatase and lactate dehydrogenase and significant decrease in the glucose -6- phosphate dehydrogenase and pyruvate dehydrogenase activities, whereas pyruvate kinase activity did not show any alteration compared to controls. Further, the glycogen and total protein contents of the liver were decreased whereas those of pyruvate and lactate showed significant increase compared to controls after RS as well as FS.The results put together indicate that acute stress induced hyperglycemia results due to increased gluconeogenesis and glycogenolysis without alteration in glycolysis. The study first time reveals that after first acute stress exposure, the subsequent stressful experience augments metabolic stress response leading to hyperglycemia. The results have relevance to human health as human beings are exposed to several stressors in a day and

Full Text Available Abstract. The role of immune factors in development of atherosclerotic process and anxiety-depressive disorders is of utmost importance. Serum levels of IL-6 and -10 were studied in forty-nine patients with acute coronary syndrome, as well as their interactions with psychological state of the patients. Serum concentrations of the cytokines proved to be higher in unstable angina. A correlation was confirmed between the cytokine levels and co-morbidity with affective disorders in acute ischaemic heart disease.

Full Text Available Background: Medical education across the globe is perceived as being inherently stressful. Studies on psychological problems such as stress, depression and anxiety among medical students have found that these disorders are under diagnosed and under treated. In this background the present study was undertaken with the objectives to assess the magni-tude of depression and its association with stress among medical students. Methods: A Cross sectional study was undertaken among 235 medical students in a private medical college, Pondicherry. Tools similar to General Health Questionaire (GHQ-12 and Beck depression Inventory (BDI was used to screen psychological stress and depression respectively. Results: The prevalence of depression was 71% among medical students. Psychological stress was associated with depression. Conclusion: Emphasize should be laid on the importance of screening for depression of medical students on a regular basis for early detection and rendering appropriate intervention like group counseling, stress management training etc. to protect the future professionals.

Background Psychological stress occurs when an individual perceives that environmental demands tax or exceed his or her adaptive capacity. Its association with severe health and emotional diseases, points out the necessity to find new efficient strategies to treat it. Moreover, psychological stress is a very personal problem and requires training focused on the specific needs of individuals. To overcome the above limitations, the INTERSTRESS project suggests the adoption of a new paradigm for...

The link between psychological stress and aging is intuitive although the underlying mechanisms are not well defined. Evidence suggests that chronic psychological stress stimulates the autonomic nervous system, renin-angiotensin system, and the hypothalamic-pituitary-adrenal axis when the body attempts to resolve perceived threats to homeostasis. Prolonged activation of these pathways can result in chronic immune dysfunction, increased production of reactive oxygen species, and DNA damage, wh...

Psychological stress can negatively impact multiple sclerosis (MS). To further understand how stress is addressed in the MS medical visit, 34 people with MS participated in focus groups. Transcripts were analyzed by inductive thematic analysis. The majority of participants did not discuss stress with their provider, citing barriers to communication such as lack of time, poor coordination between specialties, physician reliance on pharmaceutical prescription, and patient lack of self-advocacy. Participants recommended several ways to better manage psychological wellbeing in the clinical setting. These findings provide a foundation for future studies aimed at minimizing the detrimental effect of stress in MS. PMID:25527612

Respiratory sinus arrhythmia (RSA) has been conceptualized as an index of emotion regulation abilities. Although resting RSA has been associated with both concurrent and prospective affective responses to stress, the impact of RSA reactivity on emotional responses to stress is inconsistent across studies. The type of emotional stimuli used to elicit these phasic RSA responses may influence the adaptive value of RSA reactivity. We propose that RSA reactivity to a personally relevant worry-based stressor might forecast future affective responses to stress. To evaluate whether resting RSA and RSA reactivity to worry inductions predict stress-related increases in psychological distress, an academic stress model was used to prospectively examine changes in psychological distress from the well-defined low- and high-stress periods. During the low-stress period, 76 participants completed self-report mood measures and had their RSA assessed during a resting baseline, free worry period and worry catastrophizing interview. Participants completed another mood assessment during the high-stress period. Results indicated that baseline psychological distress predicted larger decreases in RSA during the worry inductions. Lower resting RSA and greater RSA suppression to the worry inductions at baseline prospectively predicted larger increases in psychological distress from the low- to high-stress period, even after accounting for the impact of baseline distress on RSA. These results provide further evidence that RSA may represent a unique index of emotion regulation abilities in times of stress. PMID:25089936

Drug residue contamination in aquatic ecosystems has been studied extensively, but the behavioral effects exerted by the presence of these drugs are not well known. Here, we investigated the effects of acute stress on anxiety, memory, social interaction, and aggressiveness in zebrafish exposed to fluoxetine and diazepam at concentrations that disrupt the hypothalamic-pituitary-interrenal (HPI) axis. Stress increased the locomotor activity and time spent in the bottom area of the tank (novel tank). Fluoxetine and diazepam prevented these behaviors. We also observed that stress and fluoxetine and diazepam exposures decreased social interaction. Stress also increased aggressive behavior, which was not reversed by fluoxetine or diazepam. These data suggest that the presence of these drugs in aquatic ecosystems causes significant behavioral alterations in fish. PMID:26403161

Rationale/statement of the problem : Considerable research has focused on the relationship of anxiety with alterations in the hypothalamic-pituitary-adrenal (HPA) acute stress response. Findings, however, differ among studies on adults and children, and among different types of anxiety. This study investigates the relationship of anxiety symptom severity with HPA reactivity to the cold pressor task (CPT) in preadolescent children. We hypothesize that children with increased symptoms of anxiet...

Psychological morbidity is increasingly reported in cancer survivors. The authors' objective was to determine the presence of acute posttraumatic stress disorder (PTSD) symptoms in prostate cancer (PC) patients following radical prostatectomy. Fifteen patients who underwent radical prostatectomy for localized prostate cancer were assessed for the presence of PTSD-related symptoms by completing the Davidson Trauma Scale (DTS), a month following the procedure. A group of 20 patients who underwent surgery for benign prostate hyperplasia (BPH) served as the control group. PTSD total scores were significantly higher in PC patients when compared with BPH patients, whose PTSD scores did not differ from those reported in the general population (32.6 ± 18.5 vs. 11.3 ± 9.7, p = .001). PTSD did not vary among PC patients when adjusted for educational status. PTSD symptoms are common among patients undergoing radical prostatectomy and independent of their educational level. Research investigating these aspects of posttreatment psychological adjustment is needed for developing well-targeted psychological interventions. PMID:20483867

The clinical features of fibromyalgia are associated with various psychological factors, including stress. We examined the hypothesis that the path that psychological factors follow in influencing fibromyalgia symptoms is through their direct effect on stress. Ninety-eight females with ACR 1990 classified fibromyalgia completed the following questionnaires: The Big 5 Personality Inventory, Fibromyalgia Impact Questionnaire, Perceived Stress Scale, Profile of Mood States, Mastery Scale, and Perceived Control of Internal States Scale. SPSS (PASW version 22) was used to perform basic t tests, means, and standard deviations to show difference between symptom characteristics. Pathway analysis using structural equation modelling (Laavan) examined the effect of stress on the relationships between psychological factors and the elements that define the fibromyalgia phenotype. The preferred model showed that the identified path clearly linked the psychological variables of anxiety, neuroticism and mastery, but not internal control, to the three key elements of fibromyalgia, namely pain, fatigue and sleep (p < 0.001), via the person's perceived stress. Confusion, however, did not fit the preferred model. This study confirms that stress is a necessary link in the pathway between certain identified, established and significant psychological factors and key fibromyalgia symptoms. This has implications for the understanding of contributing mechanisms and the clinical care of patients with fibromyalgia. PMID:27245234
We investigated the changes in 125I-iomazenil (125I-IMZ) benzodiazepine receptor (BZR) binding with psychological stress in a rat model. Six male Wistar rats were placed under psychological stress for 1 hour by using a communication box. No physical stress was not received. 1.85 MBq of 125I-IMZ was injected into the lateral tail vein and the rat was killed 3 hours later. Twenty-micormeter-thick sections of the brain were collected and % injected dose per body weight (% ID/BW) of eleven regions (frontal, parietal, temporal, occipital cortices, caudate putamen, accumubens nuclei, globus pallidus, amygdala, thalamus, hippocampus and hypothalamus) were calculated by autoradiography. The %ID/BW of rats which were placed under psychological stress was compared with that of 6 control rats. The %ID/BW of rats which were placed under psychological stress diffusely tended to show a reduction in 125I-IMZ-BZR binding. A significant decrease in BZR binding was observed in the hippocampus of the rats which were placed under psychological stress. 125I-IMZ-BZR binding tended to decrease throughout the brain. (author)

AIM: To investigate the effects of psychological stress on small intestinal motility and bacteria and mucosa in mice,and to explore the relationship between small intestinal dysfunction and small intestinal motility and bacteria and mucosa under psychological stress.METHODS: Sixty mice were randomly divided into psychological stress group and control group. Each group were subdivided into small intestinal motility group (n = 10),bacteria group (n = 10), and D-xylose administered to stomach group (n = 10). An animal model with psychological stress was established housing the mice with a hungry cat in separate layers of a two-layer cage. A semi-solid colored marker (carbon-ink) was used for monitoring small intestinal transit. The proximal small intestine was harvested under sterile condition and processed for quantitation for aerobes (Escherichia coli) and anaerobes (Lactobacilli). The quantitation of bacteria was expressed as log10(colony forming units/g). D-xylose levels in plasma were measured for estimating the damage of small intestinal mucosa.RESULTS: Small intestinal transit was inhibited (39.80±9.50% vs 58.79±11.47%, P＜0.01) in mice after psychological stress, compared with the controls. Psychological stress resulted in quantitative alterations in the aerobes (E. coli).There was an increase in the number of E. coli in the proximal small intestinal flora (1.78±0.30 log10(CFU/g) vs 1.37±0.21 log10(CFU/g), P＜0.01), and there was decrease in relative proportion of Lactobacilli and E. coli of stressed mice (0.53±0.63 vs 1.14±1.07, P＜0.05), while there was no significant difference in the anaerobes (Lactobacilli) between the two groups (2.31±0.70 log10 (CFU/g) vs 2.44±0.37 log10(CFU/g), ,P＞0.05). D-xylose concentrations in plasma in psychological stress mice were significantly higher than those in the control group (2.90±0.89 mmol/L vs 0.97±0.33 mmol/L, P＜0.01).CONCLUSION: Small intestinal dysfunction under psychological stress may be related

Full Text Available Introduction. Termination of pregnancy - induced abortion is inevitable in family planning as the final solution in resolving unwanted pregnancies. It can be the cause of major physical and phychological concequences on women’s health. Diverse opinions on psychological consequences of induced abortion can be found in literature. Material and methods. A prospective study was performed in order to predict acute stress disorder (ASD after the induced abortion and the possibility of post-traumatic stress disorder (PTSD. Seven days after the induced abortion, 40 women had to fill in: 1. a special questionnaire made for this investigation, with questions linked to some risk factors inducing stress, 2. Likert’s emotional scale and 3. Bryant’s acute stress reaction scale. Results. After an induced abortion 52.5% women had ASD and 32.5% women had PTSD. Women with ASD after the abortion developed more sense of guilt, irritability, shame, self-judgement, fear from God and self-hatred. They were less educated, had lower income, they were more religious, did not approve of abortion and had worse relationship with their partners after the abortion in comparison to women without ASD. Age, number of previous abortions and decision to abort did not differ between the two groups. Discussion and conclusion. Induced abortion represents a predisposing factor for ASD and PTSD in women. Some psychosocial factors contribute to the development of stress after abortion. Serbia has a task to reduce the number of abortions which is very high, in order, to preserve reproductive and phychological health of women.
Full Text Available Objective: Development of the central nervous system (CNS is dependent on interactionsbetween genetic and epigenetic factors, some of which could affect the susceptibilityof the developing brain to damaging insults. Gestational stress has been shown as a potentialfactor associated with higher risk of developing certain neurological and psychiatricdisorders. This study tested the hypothesis that maternal stress influences the risk ofepilepsy in offsprings.Materials and Methods: Pregnant mice were exposed to restraint stress twice a day forthree days at the start of the last week of gestation. Ten days after birth, the intact hippocampiof the newborn mice were excised and prepared for investigation. The hippocampiwere bathed in low magnesium artificial cerebrospinal fluid to induce field potential,and the subsequent spontaneous seizure-like events of the CA1 neurons were recorded.Plasma corticosterone was measured using a commercial radioimmunoassay (RIA kitand the values were expressed as μg/100 ml.Results: Both the number of recurrent seizures and the duration of seizure activity werereduced in the stressed group compared to the controls (p<0.001. Stress induced a significantrise in serum corticosterone levels in both pregnant mice and in their newbornpups (p<0.001.Conclusion: These findings suggest that acute prenatal stress, which may mimic acutestress in human pregnancy, is a likely factor affecting seizure control in childhood temporallobe epilepsy. The underlying inhibitory mechanism may be an increase in the level ofneurosteroids both in the blood and the brain.
An extensive review of literature on individual and group performance and decisionmaking under psychological stress was conducted and summarized. Specific stress-related variables relevant to reactor operation were pinpointed and incorporated in an experiment to assess the performance of reactor operators under psychological stress. The decisionmaking performance of 24 reactor operators under differing levels of workload, conflicting information, and detail of available written procedures was assessed in terms of selecting immediate, subsequent, and nonapplicable actions in response to 12 emergency scenarios resulting from a severe seismic event at a pressurized water reactor. Specific personality characteristics of the operators suggested by the literature to be related to performance under stress were assessed and correlated to decisionmaking under stress. The experimental results were statistically analyzed, and findings indicated that operator decisionmaking under stress was more accurate under lower levels of workload, with the availability of detailed procedures, and in the presence of high conflicting information

Full Text Available It has been reported that mental stress causes abnormality of spermiogram parameters. We investigated the effect of psychological stress on the L-arginine-nitric oxide (NO pathway. Semen samples were collected from 29 healthy fourth semester medical students just before (stress and 3 months after (non-stress the final examinations. Psychological stress was measured by the State Anxiety Inventory questionnaire. After standard semen analysis, arginase activity and NO concentration were measured spectrophotometrically in the seminal plasma. Measurements were made in duplicate. During the stress period, sperm concentration (41.28 ± 3.70 vs 77.62 ± 7.13 x 10(6/mL, rapid progressive motility of spermatozoa (8.79 ± 1.66 vs 20.86 ± 1.63% and seminal plasma arginase activity (0.12 ± 0.01 vs 0.22 ± 0.01 U/mL were significantly lower than in the non-stress situation, whereas seminal plasma NO (17.28 ± 0.56 vs 10.02 ± 0.49 µmol/L was higher compared to the non-stress period (P < 0.001 for all. During stress there was a negative correlation between NO concentration and sperm concentration, the percentage of rapid progressive motility and arginase activity (r = -0.622, P < 0.01; r = -0.425, P < 0.05 and r = -0.445, P < 0.05, respectively. These results indicate that psychological stress causes an increase of NO level and a decrease of arginase activity in the L-arginine-NO pathway. Furthermore, poor sperm quality may be due to excessive production of NO under psychological stress. In the light of these results, we suggest that the arginine-NO pathway, together with arginase and NO synthase, are involved in semen quality under stress conditions.

Full Text Available Among all causes of preventable deaths, smoking is responsible for the greatest number of deaths worldwide and predisposes to fatal, noncommunicable diseases, especially cardiovascular diseases. Lifestyle changes are effective in the treatment of patients with smoking-related diseases and assist in the prevention of premature mortality. Our objective was to investigate the available scientific evidence regarding the psychological distress related to smoking cessation in patients who have had acute myocardial infarction. To that end, we conducted an integrative review of the literature in order to summarize relevant studies on this topic. The selected databases were Scopus, PubMed Central, Institute for Scientific Information Web of Science (Core Collection, ScienceDirect, EMBASE, SciELO, LILACS e PsycINFO. On the basis of the inclusion and exclusion criteria adopted for this study, 14 articles were selected for analysis. Those studies showed that the prevalence of psychological distress is higher among smokers than among nonsmokers, and distress-related symptoms are much more common in smokers with acute myocardial infarction than in those without. Smoking cessation depends on the active participation of the smoker, whose major motivation is the underlying disease. Most studies have shown that there is a need to create treatment subgroups as a means of improving the treatment provided. This review article expands the knowledge regarding smoking cessation and shows the need to invest in future research that investigates subgroups of smokers diagnosed with the major smoking-related comorbidities, such as acute myocardial infarction, in order to develop specific interventions and psychological support strategies.
Full Text Available We examined the effect and relative contributions of different types of stress on the risk of hypertension. Using cluster sampling, 5,976 community-dwelling individuals aged 40-60 were selected. Hypertension was defined according to the Seventh Report of the Joint National Committee, and general psychological stress was defined as experiencing stress at work or home. Information on known risk factors of hypertension (e.g., physical activity levels, food intake, smoking behavior was collected from participants. Logistic regression analysis was used to determine the associations between psychological stress and hypertension, calculating population-attributable risks and 95% confidence intervals (CIs. General stress was significantly related to hypertension (odds ratio [OR] = 1.247, 95% CI [1.076, 1.446]. Additionally, after adjustment for all other risk factors, women showed a greater risk of hypertension if they had either stress at work or at home: OR = 1.285, 95% CI (1.027, 1.609 and OR = 1.231, 95% CI (1.001, 1.514, respectively. However, this increased risk for hypertension by stress was not found in men. General stress contributed approximately 9.1% (95% CI [3.1, 15.0] to the risk for hypertension. Thus, psychological stress was associated with an increased risk for hypertension, although this increased risk was not consistent across gender.

Mobility of mankind has increased enormously in the past few decades. People leave their homes and native countries for business and study, for vacation or to flee from unsafe conditions like wars and natural disasters. In all cases the sojourner faces a dual challenge of breaking with the familiar home environment and adjusting to new surroundings. This book deals with the psychological and health consequences of leaving the familiar home and the process of creating a new one. The focus is m...

A myocardial infarction is a rare complication which can occur after an exercise stress test. We report a 48-year-old male who was referred to the Mildura Cardiology Practice, Victoria, Australia, in August 2014 with left-sided chest pain. He underwent an exercise stress test which was negative for myocardial ischaemia. However, the patient presented to the Emergency Department of the Mildura Base Hospital 30 minutes after the test with severe retrosternal chest pain. An acute anteroseptal ST segment elevation myocardial infarction was observed on electrocardiography. After thrombolysis, he was transferred to a tertiary hospital where coronary angiography subsequently revealed significant left anterior descending coronary artery stenosis. Thrombus aspiration and a balloon angioplasty were performed. The patient was discharged three days after the surgical procedure in good health.

Neuronal genotoxic insults from oxidative stress constitute a putative molecular link between stress and depression on the one hand, and cognitive dysfunction and dementia risk on the other. Oxidative modifications to DNA are repaired by specific enzymes; a process that plays a critical role...... for maintaining genomic integrity. The aim of the present study was to characterize the pattern of cerebral DNA repair enzyme regulation after stress through the quantification of a targeted range of gene products involved in different types of DNA repair. 72 male Sprague-Dawley rats were subjected to either...... restraint stress (6h/day) or daily handling (controls), and sacrificed after 1, 7 or 21 stress sessions. The mRNA expression of seven genes (Ogg1, Ape1, Ung1, Neil1, Xrcc1, Ercc1, Nudt1) involved in the repair of oxidatively damaged DNA was determined by quantitative real time polymerase chain reaction...

Full Text Available Objective To investigate the changes of serum protein expression in soldiers under mental stress,who have undergone different psychological trainings,and to evaluate the effect of the psychological training.Methods Ninety-six male commando soldiers were randomly assigned into the common psychological training group,the circulation psychological training group,and the control group(each group comprising 32 soldiers.After four weeks of training,the soldiers in the three groups attended a high-intensity simulated anti-riot exercise.The changes in their serum protein expression were then determined using surface-enhanced laser desorption/ionization time of flight mass spectrometry(SELDI-TOF-MS combined with ProteinChip technology.Results The variance analysis showed that significant differences existed among the three groups(P < 0.05 in the relative contents of proteins,with M/Z values of 6417.8,9134.2,15171.9,and 14972.7 Da.The expression of proteins with M/Z values 9134.2 and 15171.9 Da increased in the common psychological training group compared with the control group(P < 0.05.The expression of all four proteins increased in the circulation psychological training group compared with the control group(P < 0.05.The expression of proteins with M/Z values 6417.8 and 14972.7 Da increased in the circulation psychological training group compared with the common psychological training group(P < 0.05.The classification tree formed by proteins with M/Z values 6417.8 and 14972.7 Da classified the 96 soldiers correctly,both in the learning mode and in the test mode.Conclusion Psychological training may upregulate the expression of proteins that are downregulated after stress and may improve the adaptability of soldiers to psychological stress.The effect of circulation psychological training is better than that of common psychological training.
Full Text Available Background: Parents of children with developmental problems are always bearing a load of stress. The aim of this study is to compare the stress in mothers of children with different disabilities to each other, considering their demographic background. Materials and Methods: This was a cross-sectional study conducted in Isfahan, Iran during 2012 on 285 mothers of 6-12 years old children with chronic physical disease, psychological disorder, and sensory-motor and mental problems. Abedin′s parenting stress questionnaire was used and obtained data were analyzed using multivariate analysis of variance or covariance as appropriate. Results: Mothers of children with sensory-motor mental and chronic physical problems experience more stress than mothers of children with psychological disorders (P < 0.05. The stress score of mothers of children with psychological disorders was lower than the other two groups. Also there was a significant difference between the score of mothers of children with chronic physical problems and mothers of children with psychological disorders regarding parent-child dysfunctional interaction (P < 0.01. A significant difference was observed in terms of stress among mothers of children with sensory-motor mental problems with different number of children (P < 0.05; also mothers of children with chronic physical problems in different levels of education have experienced different levels of parenting stress (P < 0.05 Conclusion: Due to high level of parenting stress among our studied samples, special education and early intervention are needed for parents in our study population in order to deepening their diagnostic knowledge and professional consultation on stress management
The purpose of the report is to consider the nature and level of psychological stress that may be associated with each of several alternatives for decontamination. The report briefly reviews some of the literature on stress, response to major disaster or life stressors, provides opinion on each decontamination alternative, and considers possible mitigative actions to reduce psychological stress. The report concludes that any procedure that is adapted for the decontamination of the reactor building atmosphere will result in some psychological stress. The stress, however, should abate as contamination is reduced and uncertainty is diminished. The advantages of the purge alternative are the rapid completion of the decontamination and the consequent elimination of future uncontrolled release. Severe stress effects are less likely if the duration of stressor exposure is reduced, if the feeling of public control is increased and if the degree of perceived safety is increased. The long delays, continued uncertainty, and possibility of uncontrolled release that characterize the other alternatives may offset the perception that they are safer. In addition, chronic stress could be a consequence of long delays and continued uncertainty

The present study examined the incidence of chronic stress in business executives (109 subjects: 75 male and 34 female) and its relationship with cortisol levels, cognitive performance, and autonomic nervous system (ANS) reactivity after an acute mental stressor. Blood samples were collected from the subjects to measure cortisol concentration. After the sample collection, the subjects completed the Lipp Inventory of Stress Symptoms for Adults and the Stroop Color-Word Test to evaluate stress and cognitive performance levels, respectively. Saliva samples were collected prior to, immediately after, and five minutes after the test. The results revealed that 90.1% of the stressed subjects experienced stress phases that are considered chronic stress. At rest, the subjects with chronic stress showed higher cortisol levels, and no gender differences were observed. No differences were found between the stressed and non-stressed subjects regarding salivary amylase activity prior to test. Chronic stress also impaired performance on the Stroop test, which revealed higher rates of error and longer reaction times in the incongruent stimulus task independently of gender. For the congruent stimulus task of the Stroop test, the stressed males presented a higher rate of errors than the non-stressed males and a longer reaction time than the stressed females. After the acute mental stressor, the non-stressed male group showed an increase in salivary alpha-amylase activity, which returned to the initial values five minutes after the test; this ANS reactivity was not observed in the chronically stressed male subjects. The ANS responses of the non-stressed vs stressed female groups were not different prior to or after the Stroop test. This study is the first to demonstrate a blunted reactivity of the ANS when male subjects with chronic psychological stress were subjected to an acute mental stressor, and this change could contribute to impairments in cognitive performance.

Full Text Available BACKGROUND: Little is known about the association between financial stress and health care outcomes. Our objective was to examine the association between self-reported financial stress during initial hospitalization and long-term outcomes after acute myocardial infarction (AMI. MATERIALS AND METHODS: We used prospective registry evaluating myocardial infarction: Event and Recovery (PREMIER data, an observational, multicenter US study of AMI patients discharged between January 2003 and June 2004. Primary outcomes were disease-specific and generic health status outcomes at 1 year (symptoms, function, and quality of life (QoL, assessed by the Seattle Angina Questionnaire [SAQ] and Short Form [SF]-12. Secondary outcomes included 1-year rehospitalization and 4-year mortality. Hierarchical regression models accounted for patient socio-demographic, clinical, and quality of care characteristics, and access and barriers to care. RESULTS: Among 2344 AMI patients, 1241 (52.9% reported no financial stress, 735 (31.4% reported low financial stress, and 368 (15.7% reported high financial stress. When comparing individuals reporting low financial stress to no financial stress, there were no significant differences in post-AMI outcomes. In contrast, individuals reporting high financial stress were more likely to have worse physical health (SF-12 PCS mean difference -3.24, 95% Confidence Interval [CI]: -4.82, -1.66, mental health (SF-12 MCS mean difference: -2.44, 95% CI: -3.83, -1.05, disease-specific QoL (SAQ QoL mean difference: -6.99, 95% CI: -9.59, -4.40, and be experiencing angina (SAQ Angina Relative Risk = 1.66, 95%CI: 1.19, 2.32 at 1 year post-AMI. While 1-year readmission rates were increased (Hazard Ratio = 1.50; 95%CI: 1.20, 1.86, 4-year mortality was no different. CONCLUSIONS: High financial stress is common and an important risk factor for worse long-term outcomes post-AMI, independent of access and barriers to care.

Money is arguably the most important resource derived from work and the most important source of stress for contemporary employees. A substantial body of research supports the relationship between access to financial resources and health and well-being, both at individual and aggregated (e.g. national) levels of analysis. Yet, surprisingly little occupational health psychology research has paid attention to financial issues experienced specifically by those in the labour force. With these issues in mind, the overarching goal of the present paper was to address conceptual and measurement issues in the study of objective and subjective aspects of financial stress and review several assessment options available to occupational health psychology researchers for both aspects of financial stress. Where appropriate, we offer guidance to researchers about choices among various financial stress measures and identify issues that require further research attention.

Full Text Available Previous studies on healing by gentle touch in clients with various illnesses indicated substantial improvements in psychological well-being, suggesting that this form of treatment might be helpful for people with impaired quality of mental health. The purpose of this study was to evaluate the effectiveness and safety of healing by gentle touch in subjects with self-reported impairments in their psychological well-being or mental health. One hundred and forty-seven clients who identified themselves as having psychological problems received four treatment sessions. Pre- to post-treatment changes in psychological and physical functioning were assessed by self-completed questionnaires which included visual analogue scales (VAS and the EuroQoL (EQ-5D. Participants recorded reductions in stress, anxiety and depression scores and increases in relaxation and ability to cope scores (all P < 0.0004. Improvements were greatest in those with the most severe symptoms initially. This open study provides strong circumstantial evidence that healing by gentle touch is safe and effective in improving psychological well-being in participants with self-reported psychological problems, and also that it safely complements standard medical treatment. Controlled trials are warranted.

The aim of this study was to examine the effectiveness of Enzyme-Treated Asparagus Extract (ETAS) on improving stress response. A randomized, double-blind, placebo-controlled cross-over trial was undertaken in healthy volunteers. ETAS (150 mg/d) or a placebo was consumed for 28 d, with a washout period. Psychological parameters were examined using a self-report scale questionnaire and psychological stress was applied using the Uchida-Kraepelin (U-K) test. During the stress load, autonomic nervous function was analyzed. After the stress load, a profile of mood states (POMS) psychological rating was performed, and serum cortisol, plasma catecholamine, salivary secretory immunoglobulin A (sIgA), and salivary cortisol were analyzed. ETAS intake improved the self-reported rating for the items "Feel tired," "Hard to get up," and "Feel heavy" in the psychological questionnaire; ameliorated the self-reported rating for the items "Depression-Dejection" and "Fatigue" in the POMS questionnaire; and increased salivary sIgA levels after the U-K test. In contrast, serum and salivary cortisol levels, and plasma catecholamine did not change. During the U-K test, ETAS significantly upregulated the sympathetic nerve activity. Furthermore, ETAS intake significantly increased the number of answers and the number of correct answers in the U-K test, suggesting that it might improve office work performance with swiftness and accuracy under stressful conditions. In conclusion, ETAS supplementation reduced feelings of dysphoria and fatigue, ameliorated quality of sleep, and enhanced stress-load performance as well as promoted stress response by increasing salivary sIgA levels. These data suggest ETAS intake may exert beneficial effects, resulting from well-controlled stress management, in healthy individuals. PMID:27465727

Individuals with ADHD suffer from increased vulnerability to environmental and mental stressors and may be at increased risk for chronic stress in everyday life. The Hypothalamic-Pituitary-Adrenal (HPA) axis is a critical physiological system that mediates responses to stress. The present study seeks to examine test performance, test anxiety, self-reported psychological stress and cortisol reactivity to mental-cognitive stress in adults with ADHD when compared with healthy controls. Stress was induced by an arithmetic ability test. Psychological stress was assessed repeatedly throughout the experimental session. Salivary cortisol, an indicator of the HPA axis function, was evaluated immediately upon arrival, as well as 1 min and 20 min post-test completion. Results revealed higher levels of test anxiety and poorer performance on the test in the ADHD group. The ADHD and control groups showed no difference in base-line levels of subjective stress and in subjective stress levels 20 min after the test. In contrast, individuals with ADHD reported significantly higher levels of stress at the test anticipation phase and 1 min post-test completion. Cortisol response to stress differed according to group: in the ADHD group, 20 min post-test cortisol levels were significantly higher than base-line cortisol levels. This was not evident in the control group. These results suggest greater activation of the HPA axis in response to stress in adults with ADHD when compared with healthy controls. Adults with ADHD do not differ from controls in basal levels of subjective stress and cortisol, but do have stronger psychophysiological reactions in response to stressful challenges. The present findings are among the first to demonstrate significant alterations in cortisol reactivity to stress in adults with ADHD. PMID:26107579

Exposure to behavioral stress normally triggers a complex, multi-level response of the hypothalamic-pituitary-adrenal (HPA) axis that helps maintain homeostatic balance. Although the endocannabinoid (eCB) system (ECS) is sensitive to chronic stress, few studies have directly addressed its response to acute stress. Here we show that acute restraint stress enhances eCB-dependent modulation of GABA release measured by whole-cell voltage clamp of inhibitory post-synaptic currents (IPSCs) in rat h...

The objective of this study was to investigate the interrelationship between chronic idiopathic urticaria (CIU), psychological co-morbidity, posttraumatic stress, repression and alexithymia. 89 participants with CIU and 105 without CIU responded to an online questionnaire. Both groups completed the general health questionnaire-12, the perceived stress scale, the posttraumatic stress diagnostic scale and the Toronto alexithymia scale-20 and were categorised into four defence mechanism groups (repressive, defensive, high-anxious, low-anxious). CIU participants also completed the Skindex-17 and a self-report severity measure. CIU participants reported higher levels of alexithymia than the control group and their defence mechanism was most likely to be categorised as defensive, with conscious self-image management reported alongside high manifest anxiety. Partial least squares analysis revealed significant paths between posttraumatic stress and CIU severity and psychological co-morbidity. Posttraumatic stress was associated with alexithymia and type of defence mechanism. Only being in the high-anxious group partially mediated the relationship between posttraumatic stress and CIU severity. In conclusion, there is evidence for a relationship between CIU and trauma. The severity of posttraumatic symptoms varies depending upon alexithymic traits and defence mechanisms used. Disease severity and psychological co-morbidity are differentially influenced by the relationships between trauma, alexithymic traits and defence mechanisms. PMID:22362490

A study was initiated to determine the effects of psychological stress on the immune response in BALB/c mice recovering from exposure to a low dose of ionizing radiation. Mice were first subjected to conditioning training for 12 days, then exposed to 200 R, subjected to psychological stress for 14 days, and assessed for peak anti-sheep RBC response. The seven treatment groups included two unirradiated groups and five irradiated groups. Mice exposed to 200 R and then subjected to conditioned psychological stress responded less vigorously to antigenic stimulation than those of the other irradiated groups. The psychological stress imposed upon these mice did not influence the antibody-forming capacity of unirradiated mice. These results indicate that a psychological stress which did not affect the immunological activity of unirradiated mice can curtail the immunological recovery of mice exposed to low doses of ionizing radiation
Full Text Available Abstract Background The hypothalamic-pituitary-adrenocortical (HPA axis and sympathetic adrenomedullary (SAM system are the major stress-response pathways. Plasma adrenocorticotropic hormone (ACTH represents HPA axis activity, while plasma catecholamines are used as markers of the SAM system. Salivary alpha amylase (AA, chromogranin A (CgA, and immunoglobulin A (IgA are candidate markers of stress activation, although their role has not been established. The Uchida-Kraepelin (U-K test is a questionnaire that requires intense concentration and effort, and has been used as a tool to induce mental stress. However, it is not clear whether or not the test is effective as a psychological/mental stressor. Methods In this study, normal young women took the U-K test and serial measurements of plasma ACTH and catecholamines (dopamine, noradrenaline, and adrenaline (n = 10, as well as salivary AA, CgA, and IgA (n = 16 before, during and after the test. Results We found no changes in any of these parameters at any time point during or after the U-K test. Conclusion Our findings indicate that the U-K test is not a suitable for measuring the psychological/mental stress of young women because the plasma data showed that it did not affect the HPA axis and SAM system. The U-K test should be employed carefully as a psychological/mental stressor due to insufficient scientific evidence of its effectiveness. In addition, salivary AA, CgA, and IgA should not simply be compared with previous reports, because the mechanism of secretion and normal range of each salivary parameter remain unknown. Salivary AA, CgA, and IgA may not be suitable candidate markers of psychological/mental stress.

Despite the prevalence of stress in everyday life and its impact on happiness, health, and cognition, little is known about the neural substrate of the experience of everyday stress in humans. We use a quantitative and noninvasive neuroimaging technique, arterial spin-labeling perfusion MRI, to measure cerebral blood flow (CBF) changes associated with mild to moderate stress induced by a mental arithmetic task with performance monitoring. Elicitation of stress was verified by self-report of stress and emotional state and measures of heart rate and salivary-cortisol level. The change in CBF induced by the stress task was positively correlated with subjective stress rating in the ventral right prefrontal cortex (RPFC) and left insula/putamen area. The ventral RPFC along with right insula/putamen and anterior cingulate showed sustained activation after task completion in subjects reporting a high stress level during arithmetic tasks. Additionally, variations of baseline CBF in the ventral RPFC and right orbitofrontal cortex were found to correlate with changes in salivary-cortisol level and heart rate caused by undergoing stress tasks. We further demonstrated that the observed right prefrontal activation could not be attributed to increased cognitive demand accompanying stress tasks and extended beyond neural pathways associated with negative emotions. Our results provide neuroimaging evidence that psychological stress induces negative emotion and vigilance and that the ventral RPFC plays a key role in the central stress response. anterior cingulate cortex | arterial spin labeling | right prefrontal cortex

Psychological stress can exert a lasting impact on the aging process. This hypothesis, long posited by Hans Selye, has been supported by evidence linking stressors with several aging-related disease phenotypes. However, little is known about the molecular mechanisms underlying this association. Among plausible mechanisms linking stress and aging, evidence supports the role of epigenetic modifications, a set of molecular processes that can be induced by environmental stressors and regulate gene expression without altering the underlying genetic sequence. In particular, recent evidence shows that psychological stress can accelerate epigenetic aging, a measure based on DNA methylation prediction of chronological age that shows promise as biomarker of aging. Some studies further suggest that epigenetic aging could be modifiable, albeit others contradict this hypothesis. Future studies will need to determine the preventability or reversibility of epigenetic aging in response to distinct interventions and the potential clinical implications of such a prevention or reversal.

The goal of this study was to develop a semi-structured clinical interview for assessing acute stress disorder (ASD) in youth and test its psychometric properties. Youth (N = 168) with an acute burn or injury were administered the acute stress disorder module of the Diagnostic Interview for Children and Adolescents (DICA-ASD). The DICA-ASD demonstrated strong psychometric properties, including high internal consistency (α = .97) and perfect diagnostic inter-rater agreement (K = 1.00). Partici...

Sleep-related experiences [Watson, D. (2001). Dissociations of the night: Individual differences in sleep-related experiences and their relation to dissociation and schizotypy. Journal of Abnormal Psychology, 110, 526-535] refer to a host of nocturnal altered-consciousness phenomena, including narcoleptic tendencies, nightmares, problem-solving dreams, waking dreams, and lucid dreams. In an attempt to clarify the meaning of this construct, we examined cross-sectional and longitudinal associations of sleep-related experiences (SREs), altered-consciousness tendencies (i.e., dissociation and transliminality), psychological distress, childhood maltreatment (i.e., abuse and neglect), and life stress in young adults. Both types of SREs (general SREs and lucid dreaming) were found to be distinguishable from altered-consciousness tendencies. Transliminality emerged as a longitudinal predictor of both general SREs and lucid dreams. Psychological distress and an increase in life stress predicted an increase in general SREs over a 3-month interval. We conclude that transliminality is a general altered-consciousness trait that accounts for some of the individual differences in sleep-related experiences, and that general sleep experiences are an outcome of psychological distress and life stress.

Full Text Available Abstract Background In recent years there has been a growing appreciation of the issues of quality of life and stresses involved medical training as this may affect their learning and academic performance. However, such studies are lacking in medical schools of Nepal. Therefore, we carried out this study to assess the prevalence of psychological morbidity, sources and severity of stress and coping strategies among medical students in our integrated problem-stimulated undergraduate medical curriculum. Methods A cross-sectional, questionnaire-based survey was carried out among the undergraduate medical students of Manipal College of Medical Sciences, Pokhara, Nepal during the time period August, 2005 to December, 2006. The psychological morbidity was assessed using General Health Questionnaire. A 24-item questionnaire was used to assess sources of stress and their severity. Coping strategies adopted was assessed using brief COPE inventory. Results The overall response rate was 75.8% (407 out of 525 students. The overall prevalence of psychological morbidity was 20.9% and was higher among students of basic sciences, Indian nationality and whose parents were medical doctors. By logistic regression analysis, GHQ-caseness was associated with occurrence of academic and health-related stressors. The most common sources of stress were related to academic and psychosocial concerns. The most important and severe sources of stress were staying in hostel, high parental expectations, vastness of syllabus, tests/exams, lack of time and facilities for entertainment. The students generally used active coping strategies and alcohol/drug was a least used coping strategy. The coping strategies commonly used by students in our institution were positive reframing, planning, acceptance, active coping, self-distraction and emotional support. The coping strategies showed variation by GHQ-caseness, year of study, gender and parents' occupation. Conclusion The higher

Aqueous extract of leaves of Nelumbo nucifera was investigated on acute stress (immobilization stress)-induced biochemical alterations in Swiss mice. The animals were also subjected to acute physical stress (swimming endurance test) and acute chemical stress (writhing test) to gauge the antistress potential of the extract. Further to evaluate the antistress activity of Nelumbo nucifera in chronic stress condition, fresh Wistar rats were subjected to cold restraint stress (4° for 1 h) for 7 da...
