Abstract: Chronic Stress in an academic environment is considered to be the physiological, emotional, cognitive and behavioral reaction to scholastic events. The objective of this study was to identify chronic stress and its association with psychological, behavioral and physiological variables of Mexican students at a public university. A representative random sample of 527 students in 2012 was assessed. The Stress Symptoms Inventory and the Rossi classification were used and a multiple regression analysis was carried out. Results showed that 35.3% of students displayed high levels of chronic stress; 44.8% medium levels and 19.9% low levels, and the variables of working, digestion problems, nail-biting, feeling depressed, isolation from others, are predictors of chronic stress. Early detection of the variables associated with chronic stress in students would facilitate the implementation of educational programs aimed at developing students’ ability to cope with stressful situations.

Abstract: background: stress and psychosocial adversity are main factors involved atthe onset and development of eating disorders (ed). objective: to compare qualitative and quantitatively the exposure to vital stressing events, psychological and behavioral characteristics among women with and without eating disorders. to correlate stress, eating disordered symptoms and socio demographic variables in both groups. method: self-evaluation scale of stress (srrs), eating attitudes test (eat-40), eating disorders inventory (edi) and the body shape questionnaire (bsq), were applied to 50 eating disordered patients and to 50 university students without these pathologies. results: patients exhibited higher levels of stress accumulated during the year before the diagnosis, where family conflicts and habit changes stood out among the stressors. the srrs (p = < 0,05), edi (p = < 0,05), eat- 40(p = < 0,05), and bsq (p = < 0,05) showed statistically meaningful differences between patients and controls. in patients stress was positively correlated mainly to perfectionism (r = 0.255) and bsq (r= 0.112); in controls, edi (r = 0.282), bmi (r= 0.282), inefectiveness (r = 0.26), eat-40 (r=0.188), maturity fears (r = 0.139), interoceptive awareness (r = 0.14) and body dissatisfaction (r = 0.116). perfectionism, drive for thinness, bulimia, maturity fears, ideal weight and bmi increase the risk to develop stress (or= > 1). it was confirmed the predictive capacity of eat-40 for ed (p = 0,046). the bsq ranged the highest scores within bulimics (148.72 (± 32.75); p < 0.05). conclusions: these results emphasize the importance of vital stress events in eating disordered patients, especially within family dynamics, in the context of primary care, and they provide guidance for future researches.

Abstract: objectives:to evaluate a descriptive model of stress that integrates an explanation of psychosomatic symptoms with the transactional theory of stress. methods:a random and stratified representative sample was selected from among the students in the school of psychology at the autonomous university of nuevo león, mexico. the subjects were chosen randomly from a student directory provided by the school. a self-administered questionnaire was used that contained the psychometric properties necessary for accurately quantifying each of the variables included in the model. results were analyzed using amos 5.0, employing the best probability method. also, the structural model was compared using discrete variables only and endogenous latent variables. results: the results that were obtained partly confirmed the model and corroborated the impact that stress and emotional exhaustion have on psychosomatic symptoms and that self-esteem, self-efficacy, and social support have on stress. the model with discrete variables [chi square test/degrees of freedom (c2/df) = 2.87; goodness of fit (gfi) = 0.985; adjusted goodness of fit (agfi) = 0.946; root mean square error of approximation (rmsea) = 0.072; incremental fit index (ifi) = 0.982] has a better fit than the model with latent variables (c2/df = 3.74; gfi = 0.924; agfi = 0.876; rmsea = 0.09, ifi = 0.927). in both cases, the fit is adequate. conclusions:the model discussed is the main contribution of this study. it is a descriptive model of psychosomatic symptoms, with a good fit, that describes 24.3% of the variance for discrete variables and 39.4% when using latent variables.

Abstract:


The current study investigates how stress and self-esteem interact in a wide range of levels. Studying the recent literature of the last five years, we understood that the findings indicated that self-esteem affected stress and it was affected from stress. This interaction takes place in different levels, including personal, psychological and professional parameters. These findings point out the importance of this interaction and the necessity of use of some stress management techniques which can not only reduce stress, but also improve self-esteem. As a result, the purpose of this literature review is to examine the connection between stress and self-esteem and to use this knowledge in order to reduce stress, improve self-esteem and as a result eliminate psychological disorders and ameliorate the quality of people’s life.

Abstract: An early unbalanced nutritional diet can induce affective disorders in adulthood. As well as stress in adolescence can accentuate these disorders. Both human and rat structural changes have been demonstrated in the hippocampus, likewise, oxidative stress may be involved in these disturbances. The objective of this study is to see the impact of a high-fructose diet (PN21) associated with chronic mild stress (CMS) at the end of adolescence (PN55) on metabolic and affective disorders in rats Wistar. This study was performed on four groups of male rats: control group, CMS for five weeks (PN55), fructose for ten weeks (PN21) and fructose for ten weeks (PN21) associated with CMS for five weeks (PN55). These animals underwent behavioral tests to evaluate their affective states (open field test, Sucrose preference test). After sacrifice, the dosage of glucose, triglycerides and total cholesterol was performed at the prefrontal cortex (CPF) and also at the hippocampus; the dosage of nitric oxide (NO) was performed, too. The bulk of our results show that fructose induces metabolic disturbances; the CMS induces a state of depression-like, while the association potentiated metabolic disturbances, depression-like state and also inducing anxiety. This study has shown that fructose and CMS can disrupt the various functions of the body and their association can potentiate these disturbances.

Abstract: ninvasive radioelectric asymmetric brain stimulation in the treatment of stress-related pain and physical problems: psychometric evaluation in a randomized, single-blind placebo-controlled, naturalistic study Original Research (4602) Total Article Views Authors: Fontani V, Rinaldi S, Aravagli L, Mannu P, Castagna A, Margotti ML Published Date September 2011 Volume 2011:4 Pages 681 - 686 DOI: http://dx.doi.org/10.2147/IJGM.S24628 Vania Fontani1, Salvatore Rinaldi1,2, Lucia Aravagli1, Piero Mannu1, Alessandro Castagna1, Matteo Lotti Margotti1 1Rinaldi-Fontani Institute, 2Medical School of Occupational Medicine, University of Florence, Florence, Italy Background: The aim of this study was to investigate the effects of noninvasive radioelectric asymmetric conveyer brain stimulation (REAC-BS) on pain and physical problems, a measurement cluster of the Psychological Stress Measure (PSM) test. When the symptoms of pain and physical problems do not respond to various therapeutic approaches such as medication, physiotherapy, and psychotherapy, they are often called medically unexplained symptoms. As such, these symptoms are reported to be a response to stressful situations or emotional states, often unknown to patients themselves. To explore the effectiveness of noninvasive radioelectric brain stimulation in the amelioration of symptoms of pain and physical problems, we administered a neuropsychophysical optimization protocol using a REAC device. Methods: The PSM, a self-administered questionnaire, was used to measure psychological stress and pain and physical problems in a group of 888 subjects. Data were collected immediately prior to and following a 4-week REAC treatment cycle. Results: There was a significant reduction in scores measuring subjective perceptions of stress for subjects treated with one cycle of neuropsychophysical optimization REAC-BS. At the end of the study, the number of treated subjects reporting symptoms of stress-related pain and physical problems on the PSM test was significantly reduced, whereas there was no difference in placebo-treated subjects. Conclusion: One cycle of neuropsychophysical optimization REAC-BS appears to reduce subjective perceptions of stress as measured by the PSM, particularly on the pain and physical problems cluster.

Patients and methods: The PSM, a self-administered questionnaire, was used to measure psychological stress and SSC for a group of 888 subjects. Data were collected immediately prior to and following the 4-week REAC-NPPO treatment cycle. Results: This study demonstrates a significant reduction in scores measuring subjective perceptions of stress for subjects treated with one cycle of REAC-NPPO. At the end-point of the study, the number of treated subjects reporting symptoms of stress-related SSC on the PSM test was significantly reduced, whereas there was no difference in sham-treated subjects. Conclusion: One cycle of REAC-NPPO appears to reduce subjective perceptions of SSC measured by the PSM. Trial registration: This trial has been registered in the Australian New Zealand Clinical Trials Registry as ACTRN12607000497404.

Abstract: introduction: nightmares are common and characteristic symptoms of posttraumatic stress disorder (ptst). their presence is directly related with the severity of the disorder, usually having a negative impact on the patient?s quality of life. they frequently become a refractory and residual symptom, and require special attention and specific treatment. objective: to review and update current knowledge on the pharmacological treatment available for ptsd nightmares. conclusion: very few studies have been done addressing the pharmacological treatment for ptsd nightmares. most have an open design or are case reports, the samples have been small with heterogeneous groups, and some of the results have been contradictory. psychotherapy, then, acquires great relevance in the treatment of nightmares, since although no studies exist that show the superiority of one modality over another (pharmacotherapy versus psychotherapy), clinical experience shows that the combination is beneficial for patients.
