Gay and bisexual men (GBM) are more likely to attempt suicide than heterosexual men. This disparity is commonly interpreted using minority stress theory; however, specific pathways from antigay stigma to suicidal behavior are poorly understood. We aimed to estimate associations between multiple constructs of stigma and suicide attempts among adult GBM, and to measure the proportion of these associations mediated by distinct suicide risk factors, thus identifying proximal points of intervention. Data were drawn from a Canadian community-based survey of adult GBM...

The honey bee is of paramount importance to humans in both agricultural and ecological settings. Honey bee colonies have suffered from increased attrition in recent years, stemming from complex interacting stresses. Defining common cellular stress responses elicited by these stressors represents a key step in understanding potential synergies. The proteostasis network is a highly conserved network of cellular stress responses involved in maintaining the homeostasis of protein production and function. Here, we have characterized the Heat Shock Response (HSR), one branch of this network, and found that its core components are conserved...

Both negative and positive social experiences during sensitive life phases profoundly shape brain and behaviour. Current research is therefore increasingly focusing on mechanisms mediating the interaction between varying life experiences and the epigenome. Here, male mice grew up under either adverse or beneficial conditions until adulthood, when they were subdivided into groups exposed to situations that either matched or mismatched previous conditions. It was investigated whether the resulting four life histories were associated with changes in anxiety-like behaviour, gene expression of selected genes involved in anxiety and stress circuits, and arginine vasopressin receptor 1a (Avpr1a) gene methylation...

OBJECTIVES: This study aimed to investigate the curvilinear relationship between extent of telecommuting and work-related well-being (ie, burnout, work engagement, and cognitive stress complaints), as well as to test whether job characteristics act as explanatory mechanisms underlying this relationship. METHODS: A sample of 878 employees from an international telecommunication company with a long history of telecommuting participated in a survey on psychosocial risk factors and well-being at work...

OBJECTIVE: Police officers in the New Orleans geographic area faced a number of challenges following Hurricane Katrina in 2005. DESIGN: This cross-sectional study examined gratitude, resilience, and satisfaction with life as mediators in the association between social support and post-traumatic stress disorder (PTSD) symptoms in 82 male and 31 female police officers. The Gratitude Questionnaire, Connor-Davidson Resilience Scale, Satisfaction with Life Scale, and the Interpersonal Support Evaluation List were used to measure gratitude, resilience, satisfaction with life, and social support, respectively...

Religious-spiritual (R/S) education helps medical students cope with caregiving stress and gain skills in interpersonal empathy needed for clinical care. Such R/S education has been introduced into K-12 and college curricula in some developed nations and has been found to positively impact student's mental health. Such a move has not yet been seen in the Indian education system. This paper aimed to examine perspectives of teachers and parents in India on appropriateness, benefits, and challenges of including R/S education into the school curriculum and also to gather their impressions on how a R/S curriculum might promote students' health...

Major Depression is a prevalent mental disorder that is characterized by negative mood and reduced motivation, and frequently results in social withdrawal and memory-related deficits. Repeated stressors, such as adverse life events, increase the risk for development of the disorder. Consequently, individual variability in stress response greatly weighs on depression-vulnerability and -resilience. Here, we employed the social defeat-induced persistent stress (SDPS) paradigm to identify depression-prone individuals and to examine the temporal development of depression in the months following exposure to brief defeat stress...

The hypothalamic-pituitary-adrenal (HPA) axis has been proposed to be a key mechanism underlying the link between adversity and mental health, but longitudinal studies on adversity and HPA-axis functioning are scarce. Here, we studied adversity-driven changes in HPA-axis functioning during adolescence (N=141). HPA-axis functioning (basal cortisol, cortisol awakening response, anticipation of, reaction to and recovery after a stress task) was measured twice, at age 16 and 19. Adversity (i.e., social defeat and loss/illness) since age 16 was measured extensively with the Life Stress Interview at age 19...

OBJECTIVE: Social relationships play important roles in emotional health, and are common targets of psychotherapeutic interventions. To better evaluate social relationship structure and function in the context of psychotherapy trials, this study introduces and psychometrically evaluates the Social Network Quality (SNQ) scales, which supplement the Social Network Index (SNI). The original SNI evaluates social network structure (i.e., extent of participation in diverse social roles and number of social relationships)...

Eating alone is driven by social and cultural factors, not solely by individual preferences. In academic research, eating alone is often simply treated as an alternative to social, commensal eating, and little is known about the practice of eating alone itself. This study employs a cross-cultural analysis to explore social and cultural associations of eating alone. The analysis is based on 1) cultural domain data, derived from principal component analysis of freelist responses, a set of words or phrases related to the topic of eating alone; and 2) in-depth interviews with 72 young adults aged 20-40 in urban Australia and Japan...

High income and wealth inequality corresponds with high rates of various health and social problems. One possible factor that could be contributing to this correlation is stress experienced by those being treated unfairly in an unequal society. The present experiment attempted to simulate aspects of income inequality in a lab setting while recording several measures of stress. Participants (n=96) were assigned to one of four groups and played a memory game against a confederate opponent to earn "money" to spend in a lab market...

Schizophrenia is a severe syndrome that affects about 1% of the world population. Since the mid-1950s, antipsychotics have been used to treat schizophrenia with preference for treating positive symptoms; however, their tolerance level is low, there are numerous side effects, and only some patients respond to the treatment. Antipsychotic medications that are more effective, better tolerated, and with fewer adverse effects are urgently needed. Given the accumulating evidence of the role filled by the ErbB signaling network in the biology of the dopamine, GABA, and glutamate systems, and in the etiology of schizophrenia, we hypothesized that the ErbB network is a candidate for development of a novel agent through which various symptoms of schizophrenia and other psychiatric disorders might be treated...

Adverse birth outcomes such as preterm birth, low-birth weight, and infant mortality continue to disproportionately affect black and poor infants in the United States. Improvements in healthcare quality and access have not eliminated these disparities. The objective of this review was to consider societal factors, including suboptimal education, income inequality, and residential segregation, that together lead to toxic environmental exposures and psychosocial stress. Many toxic chemicals, as well as psychosocial stress, contribute to the risk of adverse birth outcomes and black women often are more highly exposed than white women...

Both babies and their parents may experience a stay in the newborn intensive care unit (NICU) as a traumatic or a 'toxic stress,' which can lead to dysregulation of the hypothalamic-pituitary-adrenal axis and ultimately to poorly controlled cortisol secretion. Toxic stresses in childhood or adverse childhood experiences (ACEs) are strongly linked to poor health outcomes across the lifespan and trauma-informed care is an approach to caregiving based on the recognition of this relationship. Practitioners of trauma-informed care seek to understand clients' or patients' behaviors in light of previous traumas they have experienced, including ACEs...

PURPOSE: To examine associations between health-related quality of life (HRQoL) and anxiety symptoms across anxiety domains (obsessions/compulsions, social anxiety, panic disorder, agoraphobia, separation anxiety, physical injury fears, generalised anxiety, and posttraumatic stress) in a general adolescent population. Expanded knowledge about these associations can provide valuable information for improving interventions and prevention strategies for adolescent anxiety. METHODS: Cross-sectional data about anxiety were collected via a school survey from a community sample of Norwegian adolescents aged 12-17 (N = 1719)...

INTRODUCTION: Caregivers often experience stressful situations while in the midst of the caregiving process. Thus, various methods of coping have been widely applied and studied in previous researches. The aim of this study was to develop a novel questionnaire to assess the coping strategies employed by those who provide care to patients, and to further validate it among caregivers of schizophrenia patients in Malaysia. METHODS: This study, which involved the caregivers of schizophrenia patients from a hospital in Kuala Lumpur, Malaysia, was comprised of three parts, namely in-depth interviews, a pilot study, and the validation of the developed questionnaire, known as Caregiver Cope (CgCope(TM))...

Exposure to a stressful environment early in life can cause psychiatric disorders by disrupting circuit formation. Actin plays central roles in regulating neuronal structure and protein trafficking. We have recently reported that neonatal isolation inactivated ADF/cofilin, the actin depolymerizing factor, resulted in a reduced actin dynamics at spines and an attenuation of synaptic α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptor delivery in the juvenile rat medial prefrontal cortex (mPFC), leading to altered social behaviours...

Chronic social defeat stress (CSDS) is a well-established rodent model of depression that induces persistent social avoidance. CSDS triggers molecular adaptations throughout the mesocorticolimbic reward circuit, including changes in the activity of dopamine neurons in the ventral tegmental area (VTA), that may also influence drug reward. One limitation of traditional, physical CSDS (PS) is that injury complicates the study of opiate drugs like morphine. Thus, we sought to characterize a variation of CSDS, termed emotional CSDS (ES), that eliminates this confound...

Adrenergic signaling is known to promote tumor growth and metastasis, but the effects on tumor stroma are not well understood. An unbiased bioinformatics approach analyzing tumor samples from patients with known biobehavioral profiles identified a prominent stromal signature associated with cancer-associated fibroblasts (CAFs) in those with a high biobehavioral risk profile (high Center for Epidemiologic Studies Depression Scale [CES-D] score and low social support). In several models of epithelial ovarian cancer, daily restraint stress resulted in significantly increased CAF activation and was abrogated by a nonspecific β-blocker...
