The negative consequences of personal exclusion have been demonstrated by multiple studies. Less is known about the consequences of witnessing one’s own group being excluded by other groups, although studies suggest exclusion can be experienced vicariously and negatively affects members of the excluded group. Results of the present lab-based experiment (N= 153), indicate, in line with our predictions, that witnessing intergroup exclusion (manipulated by an adapted intergroup Cyberball paradigm) produced a sense of personal exclusion. It also increased self-reported distress and behavioral aggression measured in the Taylor Aggression Paradigm), especially among participants high on collective narcissism: a belief that the exaggerated greatness of the in-group is not sufficiently appreciated by others. Contrary to expectations, a short mindful decentration intervention (instructing participants to observe thoughts and emotions as transient mental products without engaging with them) delivered while participants were witnessing intergroup exclusion (versus inclusion) produced changes in heart rate variability reactivity indicative of emotional arousal especially among collective narcissists. We concluded that collective narcissism is associated with distress in the face of intergroup exclusion, aggressive retaliation, and in consequence it is a risk-factor predisposing group members to stress-related health and psychosocial problems. Furthermore, a mindful decentration, despite being an effective strategy to reduce maladaptive stress in most people, may be counterproductive in addressing high collective narcissists’ responses to threat to the in-group’s image.

Objective. To explore the autonomic nerve rhythm and the correlation between palpitations below the heart (PBTH) and autonomic nerve function in patients with PBTH based on heart rate variability (HRV). Methods. The outpatients or ward patients of Wenzhou Hospital of Traditional Chinese Medicine were collected and divided into two groups: the PBTH group and the normal group. The HRV of each group was detected. Single-factor statistical methods, Spearman correlation analysis, and logistic regression were used to describe and analyze the rhythm and characteristics of autonomic nerves in patients with PBTH and the correlation between PBTH and autonomic nerve function. Results. (1) In the comparison of HRV in different time periods in the same group, the SDNN, RMSSD, pNN50, TP, and HF in the PBTH group at night were significantly higher than those in the daytime ( P < 0.01 ), while the LF/HF ratio was significantly lower than that in the daytime ( P < 0.01 ). (2) In the comparison of HRV between the two groups in the same time period, the RMSSD and pNN50 of the PBTH group during the daytime period were significantly higher than those of the normal control group ( P < 0.05 ), and the LF/HF was significantly lower than that of the normal group ( P < 0.05 ). (3) In the Spearman correlation analysis, PBTH was significantly correlated with RMSSD, pNN50, and LF/HF ratio in the daytime period, with correlation coefficients of 0.424, 0.462, and −0.524, respectively ( P < 0.05 ). (4) Logistic regression analysis showed that the decrease of LF/HF ratio during the daytime period was an independent risk factor for PBTH in TCM (OR = 0.474, 95% CI: 0.230–0.977, P < 0.05 ). Conclusions. The changes in parasympathetic nerve function in patients with PBTH have a circadian rhythm, which is characterized by increased activity during the nighttime. At the same time, the autonomic nerve activity of people with PBTH during the daytime is unbalanced, and the decrease of LF/HF ratio during the day is an independent high risk factor for PBTH.

Emotion-driven impulse control difficulties are associated with negative psychological outcomes. Extant research suggests that high-frequency heart rate variability (HF-HRV) may be indicative of emotion-driven impulse control difficulties and potentially moderated by negative emotion. In the current study, 248 eleven- to 14-year-olds and their parent engaged in a negatively emotionally arousing conflict task at Time 1. Adolescents’ HF-HRV and negative emotional expression and experience were assessed before, during, and/or after the task. Adolescents reported on their levels of emotion-driven impulse control difficulties at Time 1 and one year later. Results revealed that higher levels of HF-HRV reactivity (i.e., higher HF-HRV augmentation) predicted higher levels of emotion-driven impulse control difficulties 1 year later among adolescents who experienced higher negative emotion. These findings suggest that negative emotional context should be considered when examining HF-HRV reactivity as a risk factor for emotion-driven impulse control difficulties and associated outcomes.

Background. Different methods are used to study cardiovascular parameters. Of these, heart rate variability (HRV) is a relevant marker for both athletes and physically active people. With regards to physical activity, yoga has become a popular form of activity in the recent years. In fact, research has indicated that yoga is a useful modality for both the management and prevention of several cardiovascular conditions. The purpose of the current study was to observe HRV dynamics in young women during a 6-month yoga intervention.Methods. We recruited 13 women from multiple yoga studios. All participants were practicing Hatha yoga 2 times a week for 6 months. Data were collected: a) at baseline, b) 2 months after the yoga intervention, c) 4 months after the intervention and d) 6 months after the intervention. We used wireless Bluetooth electrocardiogram (ECG) recording device. ECG HVR parameters and heart rate (HR) were used for data analysis.Results. HR dynamics showed no differences during the 6-month yoga intervention. Meanwhile, vLF parameter after relaxation and LF/HF ratio after body scan meditation significantly changed after yoga intervention. No changes were observed in LF or HF parameter dynamics.Conclusion. Our results suggest that 6 months twice per week yoga practice influences vLF and LF/HF ratio, especially during relaxation and body scan meditation. We also suggest that healthy women could benefit from practicing body scan meditation. In conclusion, through modification of emotion reactivity, regular practice of yoga can help improve stress response and offset negative consequences associated with the stress process.Keywords: yoga, heart rate variability, women’s health, ECG, stress.

The Relationship

Background: Chronic kidney disease (CKD) is a silent clinical condition associated with adverse comorbidity and high cardiovascular disease (CVD) risk. An inverse relationship with body mass index (BMI) and mortality has been demonstrated in hemodialysis patients. However, it is unclear if this risk-factor paradox is evident in non-dialysis CKD patients. The aims of this study were to explore the relationship between, nutritional status, markers of inflammation, autonomic and cardiac function with BMI. Longitudinal follow-up explored the relationship between BMI and all-cause mortality. Methods: 211-consecutive CKD patients referred for dobutamine stress echocardiography to detect or exclude myocardial ischemia were recruited. BMI, albumin, C-reactive protein (CRP) and haemoglobin (Hb) were recorded as markers of nutritional and inflammatory status. Left ventricular ejection fraction (LVEF) and heart rate variability (HRV) as an indicator of cardiac function was recorded. All subjects were followed prospectively until November 2014 and study end-point was all-cause mortality. Results: BMI was inversely associated with CKD status. After covariate adjustment, this association remained. During a mean follow-up period of 3.3±0.9 years there were 35 deaths (17%). BMI was inversely associated with all-cause mortality (HR 0.81, 95% CI 0.71-0.9). Other important independent predictors of mortality were heart rate variability (HR 0.98, 95% CI 0.97-0.99), myocardial ischemia (HR 1.37, 95% CI 1.17-1.81), and albumin (HR 0.86, 95% CI 0.81-0.92). Conclusions: The presence of a body mass index paradox exists in non-dialysis CKD patients. This risk-factor paradox was an independent predictor of all-cause mortality and may have significant clinical implications relevant to screening, assessment and treatment and requires further study.

Abstract Transformation of the maternal–fetal relationship into the mother–infant relationship remains an enigmatic process. This progression is considered using a Research Domain Criteria (RDoC) informed approach centered on domains of Arousal/Regulation, Positive/Negative Valence, and Social Processes. One hundred and fifty-eight maternal–fetal dyads began participation during pregnancy, maternal–infant dyads were followed at 6 months postpartum. Women exhibited stability in feelings of attachment to the fetus and infant, and in positive/negative appraisal of pregnancy and motherhood. Elicited maternal physiological arousal to emotionally evocative videos generated fetal heart rate variability and motor activity responses. Parasympathetic (i.e., heart rate variability) suppression in the fetus was associated with more positive and regulated infant social communication in the Face-to-Face Still Face protocol; suppression of maternal respiratory sinus arrhythmia was related to infant affect but in the opposite direction. Maternal ratings of infant temperament aligned with maternal antenatal affective valence. Attachment trajectories characterized by stability from antenatal to postnatal periods were most associated with maternal affective appraisal of pregnancy; shifts were influenced by infant characteristics and maternal sympathetic responsivity. Results illustrate how variation in arousal and regulatory systems of the pregnant woman and fetus operate within the context of maternal positive and negative valence systems to separately and jointly shape affiliation and temperament in early infancy.
