Newest firstIntroduction The COVID-19 pandemic was associated with high levels of depression and anxiety among pregnant individuals in the UK, as shown previously in the EPPOCH cohort. However, the relationships between these psychological burdens, pandemic-related stressors, and substance use in the prenatal period have not been systematically investigated. Methods To address this gap, we conducted a cross-sectional analysis…
Open article record in new tab ↗Fatty acid-binding protein 7 (FABP7) assists in the intracellular trafficking of endogenous cannabinoids and polyunsaturated fatty acids (PUFAs) and has been implicated for various psychiatric diseases. Rising evidence demonstrates the crosstalk between the endocannabinoid and dopaminergic systems, particularly in response to stress. The present study seeks to examine the role of FABP7 expression under chronic str…
Rationale The ongoing global opioid crisis underscores the need to better understand the neurobiological mechanisms underlying opioid use disorder (OUD). Stress is a key risk factor for developing and maintaining OUD. While animal models report that the endocannabinoid system (ECS) plays a modulatory role in stress response, alterations of ECS stress reactivity in individuals with OUD have yet to be studied. Objec…
Open article record in new tab ↗Objectives Multiracial (alternatively, mixed-race or biracial) college students report higher rates of alcohol/substance use than their monoracial peers, yet factors associated with this disparity remain understudied. Guided by minority stress and tension-reduction frameworks, associations of general and Multiracial discrimination experiences with psychological distress and substance use were investigated. Methods…
Open article record in new tab ↗Background Exposure to childhood maltreatment (CM) has serious consequences on the health of affected individuals, potentially elevating vulnerability to various psychopathologies, including substance use disorders (SUDs). Recent investigations have implicated several biological signaling systems in vulnerability to SUD development following CM, including the kynurenine (KYN) pathway and endocannabinoid (eCB) syst…
Background and aims Epidemiologic research suggests that adolescent cannabis use is associated with psychological distress (i.e. depression and anxiety symptoms); however, most studies have relied on 20th-century data, when cannabis was significantly less potent than today. This study aimed to estimate the association between adolescent cannabis use and psychological distress using contemporary population-based da…
BACKGROUND: Mental disorders are widely recognised as a major contributor to morbidity in prisons across the European Union, with evidence consistently indicating a markedly higher mental health burden among incarcerated individuals compared with community populations. Prison research has mainly focused on mental illness, often neglecting protective aspects of mental health from a salutogenic perspective. In Portu…
Open article record in new tab ↗Background Substance-related and behavioral addictions frequently co-occur and are increasingly conceptualized as part of an interconnected psychopathological framework. Addictive behaviors are linked to internalizing symptoms, including depression, anxiety, and stress, through shared vulnerability. Although impulsivity, anhedonia, and stress-related processes have been proposed as transdiagnostic factors, their r…
Open article record in new tab ↗The rising legal acceptance of cannabis and the high comorbidity between cannabis use disorder (CUD) and post-traumatic stress disorder (PTSD) highlight the importance of understanding how stress and cannabis influence the brain. We recently discovered that cannabinoid use promotes two PTSD-like symptoms: avoidance coping behaviors and the generalization of stress-coping responses to a neutral stimulus. Here, we u…
Open article record in new tab ↗Background Early-life stress constitutes a major risk factor for the development of neuropsychiatric and substance use disorders, exerting enduring effects on stress responsivity and emotional behavior. Maternal deprivation (MD) is a well-established model of early adversity that induces persistent neurobiological alterations. During adolescence, alcohol exposure presents an additional challenge that may interact…
Rationale Exposure to traumatic events can lead to alterations in social and anxiety-related behaviors. Emerging evidence suggests that peripheral host-defense processes are implicated in the expression of stress-induced behavioral responses and may be targeted to mitigate the negative sequalae of stress exposure. Objectives In this study, we used the peripherally restricted FAAH inhibitor URB937 to investigate th…
College students use substances for varied reasons, including to cope with stress. The parasympathetic nervous system (PNS) regulates bodily functions to promote energy conservation (the 'rest and digest' response), and individuals differ in their physiological sensitivity to challenge. It remains unclear whether greater PNS responses (i.e., declines in PNS activity, termed vagal withdrawal) to challenge could sug…
Open article record in new tab ↗Background Early life stress (ELS) increases the risk of substance use disorder (SUD) in adulthood. The pathway from ELS to SUD is hypothesized to be influenced by sex. We examine the impact of ELS on adolescent first substance use, a common precursor to adult SUDs, and test for sex differences in the relationship between ELS and risk of first use of alcohol, nicotine, and marijuana. Methods Individuals from the A…
The present study investigates the concentrations of the endocannabinoids under standardized psychosocial stress induction (TSST) and a resting condition in healthy males. Hereby, all endocannabinoids were analyzed under a standardized laboratory procedure (arachidonic acid (AA), arachidonoylethanolamide (AEA), isomeres 2-AG arachidonoylglycerol (2-AG) and palitoylethanolamide (PEA)). A total of n = 32 healthy con…
Open article record in new tab ↗Depression and obesity are comorbid conditions linked through shared neuroinflammatory and immune mechanisms. This study examined the effects of chronic cannabidiol (CBD) treatment on behavior and neuroinflammatory gene expression in female rats exposed to a combined model of high-fat diet (HFD) and unpredictable chronic mild stress (UCMS). Rats were subjected to an acute HFD for 2 weeks, followed by 4 weeks of UC…
Open article record in new tab ↗Adolescent e-cigarette and cannabis vaping have become significant public health concerns, with rates increasing in recent years. However, there is limited research on the impacts of COVID-related stress on adolescent vaping. This study examined the longitudinal impacts of COVID-related stress on adolescent e-cigarette and cannabis vaping, including the mediating role of vaping susceptibility (which measures a lac…
Substance use is a critical public health issue in the U.S., with Black communities, particularly those with criminal justice contact, disproportionately affected. Chronic exposure to stressors can lead to substance use as a coping strategy. This study used data from 1476 Black adults with criminal justice involvement from the National Survey of American Life to examine how psychosocial stress and sleep disturbanc…
Open article record in new tab ↗Rationale Social stress contributes to the development of depressive and anxiety symptomatology and promotes pro-inflammatory signaling in the central nervous system. In this study, we explored the effects of a lipid messenger with anti-inflammatory properties - oleoylethanolamide (OEA) - on the behavioral deficits caused by social stress in both male and female mice. Methods Adult mice were assigned to an experim…
Open article record in new tab ↗Objective In intensive care, delirium is frequent, prolongs the stay, increases health care costs, and worsens patient outcome. Several substances and medications as well as stress can impact the risk of delirium; however, assessment of previous exposure to psychotropic agents and stress by self-reports or third-party information is not always reliable. Hair analysis can be used to objectively assess medication an…
Depression is a mental illness characterized by despair behavior, inability to feel pleasure, and social withdrawal. Causes are not yet clarified, but stress is a condition that induces depression. Neuronal alterations, comprising maladaptive neuronal plasticity and excitability, are present in both responses to stress and depression. Fibroblast growth factor 14 (Fgf14) controls neuronal excitability and proper ac…
