Empathy and mentalizing abilities in relation to psychosocial stress in healthy adult men and women

Association between personality traits and psychological distress among postmenopausal women with coronary heart disease: A cross-sectional survey and mediation analysis

Postmenopausal women with negative personality characteristics are at an increased risk of psychological disorders, yet little is known about the mechanism underlying the relationship between type D personality and psychological distress in postmenopausal women with coronary disease. This study assessed the mediating roles of perceived social support and self-perceived burden in the relationship between type D and psychological distress based on the equity theory and stress-buffering model. Demographic characteristics, type D, psychological distress, perceived social support, and self-perceived burden were completed by 335 participants with self-reported questionnaires using a cross-sectional design in Southeast China. The results revealed that perceived social support and self-perceived burden both separately and serially mediated the relationship between type D personality and psychological distress. Effective intervention strategies aimed at improving perceived social support or reducing self-perceived burden may be beneficial in reducing psychological distress.

Spouses' coping with stress during the COVID-19 pandemic: is there a difference between male and female attitudes?

This descriptive study was conducted to determine the stress-coping status of spouses and the difference between male and female attitudes during the pandemic period. We collected data with the Personal Information Form and the Scale for Coping with Family Stressors from 533 participants. The mean age of women and men was 36.04 ± 10.04 and 37.13 ± 11.56, respectively. A significant difference in verbalizing with others, work - family segmentation, cognitive restructuring, changing behaviors, emotional disclosure, exercise, and spending more time with family was found between women and men (p < .05). A significant difference was also observed in coping mechanisms with family stressors between women and men, and thus, gender affects their coping attitudes. During crises such as pandemics, the community should be aware of the availability of mental health professionals, and spouses should also use effective coping methods with family stress at regular intervals.

Emotion recognition and baseline cortisol levels relationship in early Alzheimer disease

BACKGROUND

Emotion recognition is often impaired in early Alzheimer's disease (AD) and can be evaluated using the Reading the Mind in the Eyes Test (RMET). Similarly, cortisol levels can affect cognition and could be considered a biomarker of AD.

OBJECTIVES

The aim of this study was to analyse the relationship between the emotion recognition task and cortisol levels in participants with early Alzheimer Disease (AD).

METHODS

Complex emotion recognition was assessed with RMET, and plasma cortisol levels were determined by mass spectrometry in participants classified into mild cognitive impairment (MCI) due to AD (n = 25), mild dementia (MD) due to AD (n = 20), MCI non-AD (n = 34), MD non-AD (n = 13) and healthy controls (HC) (n = 16) groups.

RESULTS

Significantly lower positive emotion recognition was found in the MCI non-AD group (p = 0.02) and lower emotion recognition in MD (AD and non-AD) groups (p < 0.01) compared to the healthy group. In addition, significant differences were observed between cortisol and all RMET scores among the MCI and MD groups (p < 0.01). A significant correlation was also obtained between total and neutral RMET scores and cortisol levels in MD groups (p = 0.01).

CONCLUSIONS

These outcomes suggest that detection of positive emotion dysfunction could help to identify MCI non-AD patients. Furthermore, general impaired emotion recognition and high cortisol levels may be associated with cognitive impairment at mild dementia level.

Association of Diet, Body Mass Index, and Lifestyle on the Gastrointestinal Health Risk in a Sample of Adults

Gastrointestinal functional disorders are characterized by abnormalities in motility with visceral hypersensitivity, representing a global public health problem. We aimed to determine whether eating habits, lifestyle characteristics, and body mass index (BMI) are associated with gastrointestinal health risk. The Gastrointestinal Health (GIH) test of the World Gastroenterology Organization (WGO) and the Roma IV criteria were applied. We obtained information on food consumption habits and aerobic exercise, among other variables. Not exercising regularly, drinking water and eating vegetables less than recommended, having high body weight, and taking symptomatic medication were variables that explained 73% of the probabilities of not having good GIH (R² = 0.734). According to Rome IV criteria, women had a 50% higher risk than men of having functional bowel disorder (RR 1.6, 95% CI: 1.04, 2.45). Among the men studied, eating few or no vegetables and drinking less than 1 L of water daily was more frequent; however, the women had significantly more intestinal symptoms. In addition, constipation was higher among women than men (p = 0.020). All of the above explains the prognostic value of eating habits and the importance of paying attention to body weight to reduce the risk of gastrointestinal disease.

The STRESS-NL database: A resource for human acute stress studies across the Netherlands

Stress initiates a cascade of (neuro)biological, physiological, and behavioral changes, allowing us to respond to a challenging environment. The human response to acute stress can be studied in detail in controlled settings, usually in a laboratory environment. To this end, many studies employ acute stress paradigms to probe stress-related outcomes in healthy and patient populations. Though valuable, these studies in themselves often have relatively limited sample sizes. We established a data-sharing and collaborative interdisciplinary initiative, the STRESS-NL database, which combines (neuro)biological, physiological, and behavioral data across many acute stress studies in order to accelerate our understanding of the human acute stress response in health and disease (www.stressdatabase.eu). Researchers in the stress field from 12 Dutch research groups of 6 Dutch universities created a database to achieve an accurate inventory of (neuro)biological, physiological, and behavioral data from laboratory-based human studies that used acute stress tests. Currently, the STRESS-NL database consists of information on 5529 individual participants (2281 females and 3348 males, age range 6-99 years, mean age 27.7 ± 16 years) stemming from 57 experiments described in 42 independent studies. Studies often did not use the same stress paradigm; outcomes were different and measured at different time points. All studies currently included in the database assessed cortisol levels before, during and after experimental stress, but cortisol measurement will not be a strict requirement for future study inclusion. Here, we report on the creation of the STRESS-NL database and infrastructure to illustrate the potential of accumulating and combining existing data to allow meta-analytical, proof-of-principle analyses. The STRESS-NL database creates a framework that enables human stress research to take new avenues in explorative and hypothesis-driven data analyses with high statistical power. Future steps could be to incorporate new studies beyond the borders of the Netherlands; or build similar databases for experimental stress studies in rodents. In our view, there are major scientific benefits in initiating and maintaining such international efforts.

Theory of mind and hair cortisol in healthy young adults: the moderating effects of childhood trauma

Background: Experiences of negative social interactions and childhood trauma (CT) can lead to aberrant hypothalamic-pituitary-adrenal functions. Poor theory of mind (ToM) ability is related to increased social stress levels; however, studies on the relationship between ToM and cortisol remain scarce. Objective: This study aimed to evaluate the relationship between ToM and the hair cortisol concentration (HCC) in healthy young adults considering the moderating role of CT. Method: A total of 206 healthy young adults were divided into two groups based on an experience of moderate-to-severe childhood trauma (CT+ and CT-). To determine whether CT moderated the relationship between ToM and HCC, moderation analysis was conducted controlling for age, sex, years of education, and scores of perceived stress, depression, and anxiety. Results: CT+ individuals reported higher subjective stress perception and depressive symptoms than CT- individuals, whereas anxiety-related symptoms, ToM, and HCC were not different between the groups. The experience of CT significantly moderated the relationship between ToM and HCC. The association between poorer ToM ability and higher HCC was significant only in CT+ group. Conclusion: CT is a moderator of the association between ToM and HCC, indicating the importance of CT in social cognition and the stress response.

Mental well-being during the first months of Covid-19 in adults and children: behavioral evidence and neural precursors

Pandemics such as the Covid-19 pandemic have shown to impact our physical and mental well-being, with particular challenges for children and families. We describe data from 43 adults (31♀, ages = 22-51; 21 mothers) and 26 children (10♀, ages = 7-17 years) including pre-pandemic brain function and seven assessment points during the first months of the pandemic. We investigated (1) changes in child and adult well-being, (2) mother-child associations of mental well-being, and (3) associations between pre-pandemic brain activation during mentalizing and later fears or burden. In adults the prevalence of clinically significant anxiety-levels was 34.88% and subthreshold depression 32.56%. Caregiver burden in parents was moderately elevated. Overall, scores of depression, anxiety, and caregiver burden decreased across the 11 weeks after Covid-19-onset. Children's behavioral and emotional problems during Covid-19 did not significantly differ from pre-pandemic levels and decreased during restrictions. Mothers' subjective burden of care was associated with children's emotional and behavioral problems, while depression levels in mothers were related to children's mood. Furthermore, meeting friends was a significant predictor of children's mood during early restrictions. Pre-pandemic neural correlates of mentalizing in prefrontal regions preceded later development of fear of illnesses and viruses in all participants, while temporoparietal activation preceded higher subjective burden in mothers.
