Psychosocial stress (PSS) is a significant contributor of inflammation and CVD.• NLRP3 inflammasome activation amplifies inflammation in response to PSS.• ER stress is a key upstream mechanism that triggers NLRP3 inflammasome activation.• This study reveals mechanisms and targets to reduce inflammation caused by PSS. AbstractPsychosocial stress (PSS) affects all humans with different intensities and is… Continue reading Psychosocial #stress amplifies inflammation through NLRP3 Inflammasome activated by endoplasmic reticulum stress in the mouse #heart

#Dog owners’ #job #stress crosses over to their pet dogs via work-related #rumination
Job stress can have well-being consequences for the employee’s loved ones through crossover: the transference of work-related stress from an employee to their family members. Pet dogs—who most Americans view as family members—may also be susceptible to crossover. Given prior support for dogs’ abilities to perceive and absorb a human’s emotions via emotional contagion, we… Continue reading #Dog owners’ #job #stress crosses over to their pet dogs via work-related #rumination
A systematic review and Bayesian network meta-analysis on the efficacy and potential of #mobile interventions for #stress management
The increasing prevalence of stress underscores the demand for effective, self-administered mobile mental health interventions, yet their efficacy and accessibility are still unclear. Here, this systematic review and meta-analysis aimed to classify self-administered mobile stress management interventions, compare their efficacy and examine their moderators. We searched PsycINFO, PubMed, Web of Science, MEDLINE, Embase, CINAHL, Scopus… Continue reading A systematic review and Bayesian network meta-analysis on the efficacy and potential of #mobile interventions for #stress management
A dual-pathway architecture for #stress to disrupt agency and promote #habit
Chronic stress can change how we learn and, thus, how we make decisions1,2,3,4,5. Here we investigated the neuronal circuit mechanisms that enable this. Using a multifaceted systems neuroscience approach in male and female mice, we reveal a dual-pathway, amygdala–striatal neuronal circuit architecture by which a recent history of chronic stress disrupts the action–outcome learning underlying… Continue reading A dual-pathway architecture for #stress to disrupt agency and promote #habit
#Higher income is associated with greater life satisfaction, and more #stress
Is there a cost to our well-being from increased affluence? Drawing upon responses from 2.05 million U.S. adults from the Gallup Daily Poll from 2008 to 2017 we find that with household income above ~$63,000 respondents are more likely to experience stress. This contrasts with the trend below this threshold, where at higher income the… Continue reading #Higher income is associated with greater life satisfaction, and more #stress
#Cocoa flavanols rescue #stress-induced declines in endothelial function after a high-fat meal, but do not affect cerebral oxygenation during stress in young, healthy adults
Food choices during stressful periods often worsen, which can influence the impact of stress on vascular health. For instance, fat consumption impairs the recovery of endothelial function following mental stress, while flavanols have been shown to enhance recovery. This randomised, counterbalanced, double-blinded, crossover, postprandial intervention study examined whether flavanols consumed in combination with fat can… Continue reading #Cocoa flavanols rescue #stress-induced declines in endothelial function after a high-fat meal, but do not affect cerebral oxygenation during stress in young, healthy adults
Gut #microbiota regulates #stress responsivity via the circadian system
SummaryStress and circadian systems are interconnected through the hypothalamic-pituitary-adrenal (HPA) axis to maintain responses to external stimuli. Yet, the mechanisms of how such signals are orchestrated remain unknown. Here, we uncover the gut microbiota as a regulator of HPA-axis rhythmicity. Microbial depletion disturbs the brain transcriptome and metabolome in stress-responding pathways in the hippocampus and… Continue reading Gut #microbiota regulates #stress responsivity via the circadian system
Posttraumatic #Stress Disorder and Obstructive Sleep #Apnea in Twins
Key PointsQuestion What is the association of posttraumatic stress disorder (PTSD) with obstructive sleep apnea (OSA) after accounting for acknowledged medical risk factors for OSA?Findings In a cross-sectional study of 132 older male veteran twins discordant for PTSD undergoing in-laboratory polysomnography, current PTSD diagnosis and symptoms were associated independently with OSA, even after controlling for demographics, behavioral… Continue reading Posttraumatic #Stress Disorder and Obstructive Sleep #Apnea in Twins
Self-administered #mindfulness interventions reduce #stress in a large, randomized controlled multi-site study
Mindfulness witnessed a substantial popularity surge in the past decade, especially as digitally self-administered interventions became available at relatively low costs. Yet, it is uncertain whether they effectively help reduce stress. In a preregistered (OSF https://doi.org/10.17605/OSF.IO/UF4JZ; retrospective registration at ClinicalTrials.gov NCT06308744) multi-site study (nsites = 37, nparticipants = 2,239, 70.4% women, Mage = 22.4, s.d.age = 10.1, all fluent English speakers), we experimentally tested whether four single,… Continue reading Self-administered #mindfulness interventions reduce #stress in a large, randomized controlled multi-site study
