Psychotic symptoms, violent ideation, and disruptive behavior are more prevalent in a population with SARS-CoV-2 infection: a preliminary study.

JMIR Form Res 2022 May 14. Epub 2022 May 14.

Department of Electrical and Computer Engineering, Northwestern University, Evanston, US.

Background: The Coronavirus Disease 2019 (COVID-19) results from infection by SARS-CoV-2 virus to produce a range of mild to severe physical, neurologic and mental health symptoms. Indirectly, the COVID-19 pandemic has caused significant emotional distress, triggering emergence of mental health symptoms in persons not previously affected, or exacerbating symptoms in those with existing mental health conditions. Emotional distress and some mental health conditions can lead to violent ideation and disruptive behavior, including aggression, threatening acts, deliberate harm towards other people or animals, and inattention or noncompliance with education or workplace rules.

The satisfaction is mine: revenge seeking following extrinsic reward.

J Soc Psychol 2022 Jun 28:1-10. Epub 2022 Jun 28.

SWPS University of Social Sciences and Humanities.

The extrinsic reward should impede revenge-seeking if revenge is solely driven by the desire to feel gratified. Study 1 ( = 114) showed that satisfaction from receiving monetary compensation decreased thinking about getting back at the provocateur. However, Study 2 ( = 213) found that insulted participants aggressed against their partners despite fulfillment from receiving the unexpected monetary reward. Read More

Shared network-level functional alterations across substance use disorders: A multi-level kernel density meta-analysis of resting-state functional connectivity studies.

Addict Biol 2022 Jul;27(4):e13200

Department of Psychiatry, Psychotherapy and Psychosomatics, Faculty of Medicine, RWTH Aachen, Aachen, Germany.

An increasing number of neuroimaging studies indicate functional alterations in cortico-striatal loops in individuals with substance use disorders (SUD). Dysregulations in these circuits may contribute to drug-seeking and drug-consuming behaviour by impeding inhibitory control, habit formation, and reward processing. Despite evidence of network-level changes in SUD, a shared pattern of functional alterations within and between spatially distributed brain networks has not been systematically investigated.

Sociocultural context and pre-clinical pain facilitation: Multiple dimensions of racialized discrimination experienced by Latinx Americans are associated with enhanced temporal summation of pain.

J Pain 2022 Jun 23. Epub 2022 Jun 23.

Department of Psychological and Brain Sciences, Texas A&M University, 4235 TAMU, College Station, TX 77843, USA; Texas A&M Institute for Neuroscience, College Station, TX 77843, USA; Diversity Science Research Cluster, College Station, TX 77843, USA. Electronic address:

The experiences of injustice and their impacts on pain among Latinx Americans are overlooked and understudied. Multidimensional and consequential experiences of racialized discrimination are common for Latinx Americans but have not been considered as factors relevant for enhanced pain experience or risk. In this study, we focused on the experiences of Latinx Americans living in Texas by assessing multiple dimensions of racialized discrimination (total lifetime discrimination, racialized exclusion, stigmatization, discrimination in the workplace or school, and racism-related threat and aggression) and a laboratory marker of central sensitization of pain (temporal summation of mechanical pain, MTS).

Mobility Imaginaries of Humanitarian Intervention: Gender, Migration, and Violence along Mexico's Southern Border.

Heather M Wurtz

Med Anthropol Q 2022 Jun 25. Epub 2022 Jun 25.

Department of Sociomedical Sciences, Columbia University Mailman School of Public Health, New York, USA.

Thousands of Central American women have been displaced from their countries of origin by violence. While the violence committed against them is often portrayed as isolated acts of aggression, women's suffering is also produced and perpetuated by humanitarian interventions that immobilize women in dangerous transit zones. Interventions are then justified by institutional logics that juxtapose women's vulnerability against the threat of their own mobility. Read More
