BACKGROUND: Worry or fear related to speaking in front of others, or more broadly, communicating and interacting with others, is common. At elevated levels, however, it may contribute to heightened stress reactivity during acute speaking challenges. The purpose of this study was to examine multi-system physiological stress reactivity in the context of high-stakes public speaking while considering the impact of hypothesized individual difference risk factors. METHODS: University student participants (n = 95) delivering speeches as a heavily-weighted component of their final grade had saliva samples collected immediately prior to speaking, immediately after, and 20 min after speech completion...

Bifenthrin (BF) is a synthetic pyrethroid pesticide widely used in several countries to manage insect pests on diverse agricultural crops. Growing evidence indicates that BF exposure is associated with an increased risk of developing neurodegenerative disorders. However, the mechanisms by which BF induces neurological and anxiety alterations in the frontal cortex and striatum are not well known. The present in vivo study was carried out to determine whether reactive oxygen species (ROS)-mediated oxidative stress (OS) and neuroinflammation are involved in such alterations...

PURPOSE: We hypothesized that attention deficit hyperactivity symptoms would negatively correlate with the level of mindfulness. DESIGN AND METHOD: Seventy-six subjects referred to the outpatient psychiatry unit and 32 healthy control subjects filled out the Mindful Attention Awareness Scale (MAAS), the Depression Anxiety Stress Scale (DASS), the Adult ADHD Self-Report Scale (ASRS), and the Wender Utah Rating Scale (WURS). FINDINGS: Patients scored higher on ADH symptoms compared to controls (p ≤ ...

Urinary incontinence (UI) is a common symptom affecting almost one-third of adult women. UI can occur because of hypermobility or intrinsic sphincter deficiency of the urethra. Regardless its etiology, it is associated with poor quality of life and most of the incontinent women develop symptoms such as anxiety, depression, and social isolation over time. The synthetic midurethral sling (MUS) was first introduced in 1995 and quickly became the gold standard treatment for women with stress UI because of intrinsic sphincter deficiency and/or urethral hypermobility...

Trazodone (TRZ) is an antidepressant drug commonly used in the treatment of depression, anxiety, and insomnia. Although some studies demonstrated the adverse effects of TRZ related to cardiovascular system, the conflicting results were observed in these studies. Therefore, we aimed to investigate the cardiac adverse effects of TRZ in rats at repeated doses in our study. In accordance with this purpose, TRZ was administered orally to rats at 5, 10, and 20 mg/kg doses for 28 days. Electrocardiogram records, serum aspartate aminotransferase (AST), lactate dehydrogenase, creatine kinase-myoglobin band, cardiac troponin-T (cTn-T) levels, DNA damage in cardiomyocytes, and histologic view of heart tissues were evaluated...

This study was conducted to test whether the weight outcomes in an online social networking group were mediated by changes to psychological outcome measures in overweight and obese individuals, following a weight management programme delivered via Facebook. The data analysed in this study were collected during a three-armed, randomised, controlled clinical weight management trial conducted with overweight and obese adults over 24 weeks. Two intervention groups were given the same weight management programme: one within a Facebook group, along with peer support from other group members (the Facebook Group); the other group received the same programme in a pamphlet (the Pamphlet Group)...

The relative health of a field of research can be approximated by assessing peer-reviewed journal publication trends for articles pertinent to that field. The most recent comprehensive assessment of publication trends in the anxiety disorders indicated that the field was on a continuing trajectory of growth (Boschen, 2008). We conducted an updated search of Medline for publications on each of the anxiety disorders from 2006 to 2016. Results indicated that there was continuing growth in anxiety disorders research overall and, particularly, for posttraumatic stress disorder, social anxiety disorder, generalized anxiety disorder, and obsessive compulsive disorder...

INTRODUCTION: Sleep quality relates to mental health in clinical and non-clinical populations. However, there is more evidence of this relationship in clinical populations. Therefore, there is lack of evidence on how these variables relate and on which sociodemographic factors influence this relationship in non-clinical populations. In this study we hypothesize that in a non-clinical population sleep quality predicts mental health indicators and that age, country and gender moderate this relationship...

BACKGROUND: Corticotrophin-releasing hormone receptor-1 gene (CRHR1) variants have been implicated in mental health. However, little is known of the effects of CRHR1 on long-term mental health and behavior in presence of environmental stressors. We assess the effects of CRHR1 variant (rs17689918)-by-environment interactions on emotionality and behavioral traits, including anxiety, depression, aggression and antisocial behaviors. We also determine effects of rs17689918-by-environment-by-sex interactions on the above-mentioned outcomes...

The fetal brain is highly susceptible to stress in late pregnancy, with lifelong effects of stress on physiology and behavior. The aim of this study was to determine the physiological and behavioral effects of prenatal stress during the prepubertal period of female and male rats. We subjected pregnant Sprague-Dawley rats to a restraint stress protocol from gestational day 14 until 21, a critical period for fetal brain susceptibility to stress effects. Male and female offspring were subsequently assessed at postnatal day 24 for anxiety- and depressive-like behaviors, and spontaneous social interaction...

An exaggerated acoustic startle reflex (ASR) is a clinical indicator of anxiety disorders, such as post-traumatic stress disorder (PTSD). Given the prevalence of PTSD following traumatic brain injury (TBI), we studied the effects of TBI on ASR. Adult Sprague Dawley rats exposed to moderate controlled cortical impact injury model of TBI displayed suppression of ASR intensity and sensitivity. As patients with PTSD have been shown to display hyperactive startle responses, the present discrepant observation of TBI-induced suppression of ASR has clinical implications, in that the reduced, instead of elevated, startle response in patients with comorbid TBI/PTSD could be owing to a masking effect of TBI...

Mechanical ventilation in the intensive care unit requires the use of medication to reduce pain, discomfort, anxiety, and agitation. An explicit recall refers to the phenomenon where the person remembers the perceptions that occurred under sedation during mechanical ventilation. Severe psychological consequences may occur as a result of an explicit recall. This phenomenon is not well-defined and there is no common language in the literature. A conceptual analysis was carried out using Rodgers' evolutionary method in order to clarify the concept of explicit recall...

Joseph Maroon, Jeff Bost
Background: Numerous physical, psychological, and emotional benefits have been attributed to marijuana since its first reported use in 2,600 BC in a Chinese pharmacopoeia. The phytocannabinoids, cannabidiol (CBD), and delta-9-tetrahydrocannabinol (Δ9-THC) are the most studied extracts from cannabis sativa subspecies hemp and marijuana. CBD and Δ9-THC interact uniquely with the endocannabinoid system (ECS). Through direct and indirect actions, intrinsic endocannabinoids and plant-based phytocannabinoids modulate and influence a variety of physiological systems influenced by the ECS...

Kappa opioid receptor activation has been linked to stress and anxiety behavior, thus leading to kappa antagonists being popularized in research as potential anxiolytics. However, while these findings may hold true in standard models, the neuromodulatory effects of social defeat may change the behavioral outcome of kappa opioid receptor activation. Previous research has shown that social defeat can lead to hyperactivity of serotonergic neurons in the dorsal raphe nucleus, and that inhibition of this increase blocks the social deficits caused by defeat...

OBJECTIVE: Plantar heel pain (PHP) is often disabling, and persistent symptoms are common. Psychosocial variables are known to affect pain and disability but the association of these factors with PHP has yet to be established. The purpose of the present systematic review was to determine if psychosocial variables are associated with the presence, severity and prognosis of PHP. METHODS: A systematic review of the literature and qualitative synthesis was carried out...

Stress and anxiety are states which sportsmen are continuously exposed to. Our study aimed to evaluate neuroelectrical peripheral and central nervous system responses of sportsmen (SPR) and sedentary individuals (SED) during concentration grid test (CGT) employed under time pressure. Forty three SPR and 33 SED participated in the study. Neuroelectrical responses were simultaneously obtained during baseline and CGT. All responses were observed to increase under stress in both SED and SPR. The SPR's stress related peripheral responses were lower than SED's...

Medical students are exposed to multiple factors during their academic and clinical study that have been shown to contribute to high levels of depression, anxiety, and stress. The purpose of this article was to explore the issue of depression in the medical student population, including prevalence, causes, and key issues, along with suggestions for early identification and support from one medical school in New Zealand. After establishing that the prevalence of depression is higher for medical students than the general population, the key issues explored include assessment used in the program, characteristics of the student population (such as Type A personality and perfectionism), resilience, selection procedures, students' motivation, and the nature of the clinical environment...
