PURPOSE OF REVIEW
Although anecdotal evidence has long suggested links between emotion and ventricular arrhythmia, more recent studies have prospectively demonstrated the arrhythmogenic effects of anger, as well as mechanisms underlying these effects.
RECENT FINDINGS
Epidemiological studies reveal that psychological stress increases sudden death, as well as arrhythmias, in patients with implantable cardioverter-defibrillators, in populations during emotionally devastating disasters such as earthquake or war. Diary-based studies confirm that anger and other negative emotions can trigger potentially lethal ventricular arrhythmias. Anger alters electrophysiological properties of the myocardium, including T-wave alternans, a measure of heterogeneity of repolarization, suggesting one mechanistic link between emotion and arrhythmia. Pilot studies of behavioral interventions have shown promise in decreasing arrhythmias in patients with implantable cardioverter-defibrillators.
SUMMARY
Anger and other strong emotions can trigger polymorphic, potentially life-threatening ventricular arrhythmias in vulnerable patients. Through autonomic changes including increased sympathetic activity and vagal withdrawal, anger leads to increases in heterogeneity of repolarization as measured by T-wave alternans, known to be associated with arrhythmogenesis, as well as increasing inducibility of arrhythmia. Further delineation of mechanisms linking anger and arrhythmia, and of approaches to decrease the detrimental effects of anger and other negative emotions on arrhythmogenesis, are important areas of future investigation.

The present study is focused on anger expression and regulation within the National Institute of Mental Health (NIMH) Research Domain Criteria (RDoC) construct of Frustrative Nonreward. Although previous studies have examined associations between child anger regulation and expression, these studies do not directly address the dynamic processes involved in Frustrative Nonreward using microlongitudinal methods. The current study used data from 561 adopted children, their adoptive parents, and birth parents and aimed to address gaps in the literature by examining: (a) temporal associations between anger expression during a frustrating situation, and behaviors thought to regulate emotions (e.g., attempt-to-escape, support-seeking, distraction, and focus-on-restraint) on a microlongitudinal scale during an arm restraint task assessed at 27 months; (b) birth parent externalizing problems and overreactive parenting by adoptive parents as predictors of child anger expression and moderators of the moment-to-moment associations estimated in Step 1; and (c) longitudinal associations (linear vs. quadratic) between anger expressions and externalizing behaviors at 4.5 years. Findings indicated that children's attempt-to-escape and support-seeking predicted an increase in anger expression in the following 3-s interval, whereas distraction and focus-on-restraint were not associated with changes in anger expression. Furthermore, we found that birth parents' externalizing problems were significantly associated with child anger expression, suggesting heritable influences. Anger expression showed a U-shaped longitudinal association with paternal report of externalizing behaviors at 4.5 years. Taken together, the findings emphasize the significance of integrating microlongitudinal analysis approaches into the RDoC framework, helping to advance our understanding of dynamic processes underlying reactions to Frustrative Nonreward.

Persistent intense anger is indicative of postpartum distress, yet maternal anger has been little explored after childbirth. Using grounded theory, we explained how and why mothers develop intense anger after childbirth and the actions they take to manage their anger. Twenty mothers of healthy singleton infants described their experiences of anger during the first two postpartum years. Mothers indicated they became angry when they had violated expectations, compromised needs, and felt on edge (e.g., exhausted, stressed, and resentful), particularly around infants' sleep. Mothers described suppressing and/or expressing anger with outcomes such as conflict and recruiting support. Receiving support from partners, family, and others helped mothers manage their anger, with more positive outcomes. Women should be screened for intense anger, maternal-infant sleep problems, and adequacy of social supports after childbirth. Maternal anger can be reduced by changing expectations and helping mothers meet their needs through social and structural supports.

Anger and aggression are common sources of distress and impairment. There is, however, no available data on anger and aggression based on bibliometric analysis. This study uses bibliometric analysis to analyze research hotspots and trends in anger and aggression. Publications on anger and aggression within the last ten years were collected from the Web of Science Core Collection. Using descriptive bibliometrics, journals, countries, institutions, authors, references, and keywords in anger and aggression research were visually analyzed via CiteSpace. A total of 3114 articles were included, and studies on anger and aggression increased yearly. The publications are mainly from 106 countries led by the USA and 381 institutions led by Univ Penn. We identified 505 authors, where Emil F. Coccaro had the highest number of articles, while Buss A.H. was the most frequently co-cited author. AGGRESSIVE BEHAVIOR is the journal that bore most of the studies, while PLOS ONE was the most cited journal. Our analysis demonstrated that research on anger and aggression is flourishing. Behaviors of anger and aggression, risk factors, neural mechanisms, personality, and adolescence have been researched hotspots in the past ten years. Besides, victimization, drosophila melanogaster, psychopathic traits, and perpetration are emerging anger and aggression research trends.

Review
Irritability, defined as an increased propensity to exhibit increased anger relative to one's peers, is a common clinical problem in youth. Irritability can be conceptualized as aberrant responses to frustration (where frustration is the emotional response to blocked goal attainment) and/or aberrant 'approach' responses to threat. Irritable youth show hyper-reactivity to threat mediated by dysfunction in amygdala, medial prefrontal cortex (mPFC), anterior cingulate cortex (ACC), insula, striatum, and association cortex. Irritable youth also show abnormalities in reward learning, cognitive control, and responses to frustration. These abnormalities are mediated by circuitry that includes the inferior frontal gyrus (iFG), striatum, ACC, and parietal cortex. Effective treatments for irritability are lacking, but pathophysiological research could lead to more precisely targeted interventions.

In the present research we tested the differential effects of anger versus shame as emotional predictors of ingroup disidentification in one rather collectivistic (Japan) and two rather individualistic societies (Germany, Canada). We tested the idea that individuals cope with socially undesired emotions by disidentifying from their group. Specifically, we predicted that after a group conflict, anger, an undesired emotion in Japan, would elicit disidentification in Japan, whereas shame, an undesired emotion in Canada and Germany, would elicit disidentification in Germany and Canada. Study 1 (N = 378) found that anger, but not shame, was related to disidentification in Japan, whereas shame, but not anger, was related to disidentification in Canada and Germany. Study 2 (N = 171) shows that, after group conflict, Japanese disidentified more when imagining to feel angry, whereas Germans disidentified more when imagining to feel ashamed. Implications for these findings are discussed.

Meta-Analysis
New insights into the functional neuroanatomic correlates of emotions point toward the involvement of the cerebellum in anger and aggression. To identify cerebellar regions commonly activated in tasks examining the experience of anger and threat as well as exerting an aggressive response, two coordinate-based activation likelihood estimation meta-analyses reporting a total of 57 cerebellar activation foci from 819 participants were performed. For anger processing (18 studies), results showed significant clusters in the bilateral posterior cerebellum, overlapping with results from previous meta-analyses on emotion processing, and implying functional connectivity to cognitive, limbic, and social canonic networks in the cerebral cortex. By contrast, active aggression expression (10 studies) was associated with significant clusters in more anterior regions of the cerebellum, overlapping with cerebellar somatosensory and motor regions and displaying functional connectivity with the somatomotor and default mode network. This study not only strengthens the notion that the cerebellum is involved in emotion processing, but also provides the first quantitative evidence for distinct cerebellar functional activation patterns related to anger and aggression.

BACKGROUND
Research has shown that emotional intelligence and anger are significant predictors of both subjective and objective health. The present study aimed to draw a comparison between migraine patients and healthy individuals in terms of emotional intelligence and anger. In addition, there was an attempt to investigate the predictive role of emotional intelligence and anger in chronic migraine.
METHODS
This comparative study was carried out on 494 individuals including patients with chronic migraine (n=250) and healthy controls (n=244) in Shiraz between August 2019 and February 2020. The participants with chronic migraine and healthy controls were selected using convenience sampling and multistage sampling, respectively. Participants completed validated self-report questionnaires: Bradberry and Greaves emotional intelligence test and the provocation inventory. The data were analyzed using SPSS software (version 22.0) and chi-square test, t test and logistic regression were used. The significance level was set at P<0.05.
RESULTS
The results of independent t-test indicated that the mean intensity of anger was significantly higher among the patients with migraine (51.52±15.66) compared to the healthy controls (28.39±9.85) (P<0.001). The mean score of emotional intelligence was significantly lower among the patients with migraine (75.92±8.23) in comparison to the healthy controls (116.23±12.28) (P<0.001). Binary logistic regression revealed that neither age (P=0.72), sex (P=0.62), marital status (P=0.63) and education level (P=0.68), nor anger (P=0.24) was significantly associated with chronic migraine. However, emotional intelligence had a negative association with chronic migraine (B=-1.13, OR=0.32, P<0.001).
CONCLUSION
The results showed that a low level of emotional intelligence was associated with chronic migraine. The current results could help clinicians in planning for successful pain management/prevention programs.

BACKGROUND
Accurate recognition of the emotions of others is an important part of healthy neurological development and promotes positive psychosocial adaptation. Differences in emotional recognition may be associated with the presence of emotional biases and can alter one's perception, thus influencing their overall social cognition abilities. The present study aims to extend our collective understanding of emotion attribution abnormalities in individuals with Intermittent Explosive Disorder (IED).
METHODS
Two-hundred and forty-two adults participated, separated into groups of those diagnosed with IED according to DSM 5 criteria, Psychiatric Controls (PC), and Healthy Controls (HC). Participants completed a modified version of the Emotional Attribution Task wherein they attributed an emotion to the main character of a short vignette.
RESULTS
Participants with IED correctly identified anger stories and misattributed anger to non-anger stories significantly more often than PC and HC participants. They were also significantly less likely than HC participants to correctly identify "sad stories."
LIMITATIONS
We utilized self-report assessments in a community-recruited sample. Replication in a clinical is suggested.
CONCLUSIONS
Findings from this study support the validity of IED as a diagnostic entity and provide important information about how individuals with psychiatric disorders perceive and experience emotional cues.
