Int Immunopharmacol 2024; 138:112513. [PMID: 38917520 DOI: 10.1016/j.intimp.2024.112513] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2024] [Revised: 06/16/2024] [Accepted: 06/16/2024] [Indexed: 06/27/2024]
Abstract
In specific pathological conditions, addressing liver injury may yield favorable effects on renal function through the phenomenon of liver-kidney crosstalk. Mitochondrial DNA (mtDNA) possesses the capability to trigger downstream pathways of inflammatory cytokines, ultimately leading to immune-mediated organ damage. Consequently, understanding the intricate molecular mechanisms governing mtDNA involvement in diseases characterized by liver-kidney crosstalk is of paramount significance. This study seeks to elucidate the role of mtDNA in conditions marked by liver-kidney crosstalk. In previous clinical cases, it has been observed that patients with Trichloroethylene Hypersensitivity Syndrome (TCE-HS) who experience severe liver injury often also exhibit renal injury. In this study, patients diagnosed with trichloroethylene hypersensitivity syndrome were recruited from Shenzhen Occupational Disease Control Center. And Balb/c mice were treated with trichloroethylene. The correlation between liver and kidney injuries in patients with TCE-HS was assessed using Enzyme-Linked Immunosorbent Assay (ELISA). Alterations in mtDNA levels were examined in mouse hepatocytes, red blood cells (RBCs), and renal tubular epithelial cells utilizing immunofluorescence and PCR techniques. TCE-sensitized mice exhibited a significant increase in reactive oxygen species (ROS) and the opening of the mitochondrial permeability transition pore in hepatocytes, resulting in the release of mtDNA. Furthermore, heightened levels of mtDNA and Toll-like Receptor 9 (TLR9) expression were observed in RBCs. Additional experiments demonstrated elevated expression of TLR9 and its downstream mediator MyD88 in renal tubule epithelial cells of TCE-sensitized mice. In vitro investigations confirmed that mtDNA activates the TLR9 pathway in TCMK-1 cells. Collectively, these results suggest that mtDNA released from mitochondrial damage in hepatocytes is carried by RBCs to renal tubular epithelial cells and mediates inflammatory injury in renal tubular epithelial cells through activation of the TLR9 receptor.

Dailey SF, Dubrow S. Police-mental health partnerships and persons with severe mental illness: An exploratory study of perceived risk and use of force. INTERNATIONAL JOURNAL OF LAW AND PSYCHIATRY 2024; 93:101968. [PMID: 38394859 DOI: 10.1016/j.ijlp.2024.101968] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Revised: 12/30/2023] [Accepted: 02/17/2024] [Indexed: 02/25/2024]
Abstract
There is a need to maximize understanding of conditions under which officers are most likely to use lethal force when interacting with persons with severe mental illness (SMI) and whether utilization of a mental health professional (MHP) serves to reduce use of force (UoF) severity. Using a mixed methods concurrent triangulation design framework, this exploratory study examined UoF with individuals exhibiting signs of psychosis and whether police-MHP partnerships decrease UoF severity. Findings indicate officers use more severe forms of force with armed individuals displaying signs of psychosis and that MHP presence did not reduce force severity in such cases. Qualitative themes provide context for these findings and include (1) concerns for MHP safety, (2) planned collaborations support safety, and (3) MHPs support de-escalation. Discussion highlights a need for increased officer education on SMI, appropriate de-escalation strategies, co-created engagement/disengagement protocols for MHPs, and defined standards of practice for police-mental health collaborations.

Abstract
According to the Centers for Disease Control and Prevention, over 61 million Americans have a disability, which translates to about 26 percent of the national population. The most common types of disability are physical (13.7 percent), or those that impact mobility, and intellectual (10.8 percent), or those related to cognitive processing. The Bureau of Justice Statistics has reported that 32 percent of people in state prisons and 40 percent of people in county jails have at least one disability, rates that demonstrate alarming disproportionality. Yet the history of the disability rights movement, the impact of the Americans with Disabilities Act for people with disabilities who are involved with the criminal justice system, and the implications of disability justice and critical disability theory for the field of social work are not well understood. The purpose of this article is to review these under-recognized topics and offer recommendations for addressing this neglected area of social work education, research, policy, and practice.

Abstract
INTRODUCTION Police violence is a growing public health issue in the USA. Emerging evidence suggests that negative police encounters are associated with adverse physical and mental health outcomes. There is a critical need to examine the relationship between police violence and health disparities. However, the lack of consensus on a conceptual and operational definition of police violence is a limitation in scientific investigations on police violence and its health impacts. Here, we present the protocol for a scoping review that maps definitions, measures and methodologies of assessing police violence in the health literature. METHODS AND ANALYSIS We will comprehensively search PubMed, Cumulative Index to Nursing and Allied Health Literature and APA PsycInfo databases. We will use the following string of key terms separated with the Boolean operator 'or': 'police violence', 'police brutality', 'police use of force', 'law enforcement violence', 'law enforcement brutality', 'law enforcement use of force' and 'legal intervention'. An English language limit will be applied. We will include studies published in English or that have an English language abstract available. Eligible studies will include: (1) a definition of police violence and/or (2) a measurement of police violence. ETHICS AND DISSEMINATION This scoping review does not require ethical approval. The findings of this review will be disseminated through publication in a peer-reviewed journal and at conferences.

CRIMINAL BEHAVIOUR AND MENTAL HEALTH : CBMH 2022; 32:284-294.

Abstract
BACKGROUND Following several high-profile police shootings of Black Americans, renewed debate has focused on race as a predictor of police violence. Past research has been inconsistent on this score. Some scholars argue that socioeconomic issues are better predictors of police-related violence than are race and ethnicity. AIMS To test relationships between complaints of excessive use of police violence and racial/ethnic population demographics, allowing for social and mental health variables. METHODS We examined records from all 195 municipal police departments in California to identify complaints of excessive force by police and tested for associations between such complaints and health, socio-economic and demographic data from county records, using multivariate analyses. RESULTS There was no difference in reporting between communities according to Black or White American residency proportions; communities with more Latino Americans were less likely to complain formally of excessive use of police force. The strongest associate of complaints to police departments that their employees had used excessive force was experiencing mental distress in the community. CONCLUSIONS Our findings are limited by reliance on complaints to police authorities rather than actual incidence of police use of excessive force and by having to map municipal data on to county data, but the finding that factors other than or in addition to any inherent police problems may contribute to excessive use of force by the police offers new lines for remedying the problem. In particular, our findings suggest that more training for police in recognising and managing mental distress and more provision of mental health experts to work alongside police would be worth evaluating as a next step.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease worldwide, and scientific studies consistently report that NAFLD development can be accelerated by oxidative stress. Oxidative stress can induce the progression of NAFLD to NASH by stimulating Kupffer cells, hepatic stellate cells, and hepatocytes. Therefore, studies are underway to identify the role of antioxidants in the treatment of NAFLD. In this review, we have summarized the origins of reactive oxygen species (ROS) in cells, the relationship between ROS and NAFLD, and have discussed the use of antioxidants as therapeutic agents for NAFLD.

Abstract
Despite their enormous potential impact on population health and health inequities, police violence and use of excessive force have only recently been addressed from a public health perspective. Moving to change this state of affairs, this article considers police violence in the USA within a social determinants and health disparities framework, highlighting recent literature linking this exposure to mental health symptoms, physical health conditions, and premature mortality. The review demonstrates that police violence is common in the USA; is disproportionately directed toward Black, Latinx, and other marginalized communities; and exerts a significant and adverse effect on a broad range of health outcomes. The state-sponsored nature of police violence, its embedding within a historical and contemporary context of structural racism, and the unique circumstances of the exposure itself make it an especially salient and impactful form of violence exposure, both overlapping with and distinct from other forms of violence. We conclude by noting potential solutions that clinicaly psychology and allied fields may offer to alleviate the impact of police violence, while simultaneously recognizing that a true solution to this issue requires a drastic reformation or replacement of the criminal justice system, as well as addressing the broader context of structural and systemic racism in the USA. Expected final online publication date for the Annual Review of Clinical Psychology, Volume 18 is May 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.
