We investigated the role of COVID-19 exposure and discrimination on depressive and posttraumatic stress symptoms among Latinx adults residing in the southeastern United States. Survey data were collected from 264 Latinx adults. Using structural equation modeling (SEM) procedures, we estimated a structural model for hypothesized direct and indirect relationships between the risk factors of COVID-19 exposure and discrimination, social support, and two mental health conditions: depression and posttraumatic stress. COVID-19 exposure and discrimination each had a significant and positive relationship with both depression and posttraumatic stress. Social support was found to have a significant and inverse relationship with depression and posttraumatic stress, as well as to mediate the relationship between discrimination and both mental health symptoms. Implications for service provision and program design are presented. Future studies should examine variation between southeastern states and consider the influence of documentation status among an immigrant-only sample.

Background: Traumatic brain injury (TBI) is a significant public health issue and a leading cause of death and disability globally. Advances in clinical care have improved survival rates, leading to a growing population living with long-term effects of TBI, which can impact physical, cognitive, and emotional health. These effects often require continuous management and individualized care.

Purpose: A quarter of ICU-patients develop post-traumatic stress disorder (PTSD) after discharge. These patients could benefit from early detection of PTSD. Therefore, we explored the accuracy of text mining with self-narratives to identify intensive care unit (ICU) patients and surviving relatives at risk of PTSD in a pilot study.

Alternating bilateral sensory stimulation (ABS) is a clinical physical therapy technique effective in treating post-traumatic stress disorder (PTSD). However, its utilization in treating conditions beyond PTSD remains limited. Here, we present a protocol to reduce ethanol-induced conditioned place preference (CPP) using 4 Hz ABS.

Backgrounds: Memory and emotion are especially vulnerable to psychiatric disorders such as post-traumatic stress disorder (PTSD), which is linked to disruptions in serotonin (5-HT) metabolism. Over 90% of the 5-HT precursor tryptophan (Trp) is metabolized via the Trp-kynurenine (KYN) metabolic pathway, which generates a variety of bioactive molecules. Dysregulation of KYN metabolism, particularly low levels of kynurenic acid (KYNA), appears to be linked to neuropsychiatric disorders.

Psychedelics, historically celebrated for their cultural and spiritual significance, have emerged as potential breakthrough therapeutic agents due to their profound effects on consciousness, emotional processing, mood, and neural plasticity. This review explores the mechanisms underlying psychedelics' effects, focusing on their ability to modulate brain connectivity and neural circuit activity, including the default mode network (DMN), cortico-striatal thalamo-cortical (CSTC) loops, and the relaxed beliefs under psychedelics (REBUS) model. Advanced neuroimaging techniques reveal psychedelics' capacity to enhance functional connectivity between sensory cerebral areas while reducing the connections between associative brain areas, decreasing the rigidity and rendering the brain more plastic and susceptible to external changings, offering insights into their therapeutic outcome.
