Background: Cannabis refusal self-efficacy (CRSE), as the people´s belief about their capacity to resist cannabis, has been probed to predict cannabis use and related behaviors. The CRSE Questionnaire (CRSEQ) has 14 items grouped into Emotional Relief Self-Efficacy (6 items), Opportunistic Self-Efficacy (5 items), and Social Facilitation (3 items), forming a CRSE higher-order factor.Objective: To validate the CRSEQ for its use in the Chilean population.Method: The CRSEQ was administered to 1,275 individuals aged 12 to 77 (835 females). Confirmatory Factor Analysis was used to evaluate 14-item and 19-item models. Estimates of internal consistency, temporal stability, and convergent validity with cannabis use behaviors and reward sensitivity were obtained. Additionally, three multigroup invariance tests were conducted.Results: Both models exhibited good fit indices. The 14-item model showed χ² (74) = 245.662, p < .001, CFI = .974, RMSEA = .047, indicating slightly better fit compared to the 19-item model, which showed χ² (149) = 559.596, p < .001, CFI = .958, RMSEA = .051. Both models showed strong internal consistency (α = .80 to .96 for the 14-item model, α = .80 to .96 for the 19-item model), moderate to high temporal stability (ICCs 14-item model/ 19-item model: ERSE = .77/.78, OSE = .88/.89, SF = .82/.82), and significant convergent validity (correlations with cannabis use behaviors: .22 to .58).Conclusion: The better fit of the 14-item model makes it suitable for most applications. Convergent validity and multigroup invariance analyses confirmed the questionnaire's equivalence across sex, age groups, and cannabis use problem status. This allows for meaningful comparisons of cannabis refusal self-efficacy between different demographic groups, facilitating its applicability in diverse settings such as educational institutions and substance use treatment centers.

Background: Methamphetamine is a psychoactive substance that competes with the dopamine transporter, disrupting its flow and storage. This can trigger oxidative stress, finally resulting in neural cell death. Due to the increasing prevalence of methamphetamine use, extensive research has been devoted to finding treatments that ameliorate its detrimental effects. Naringenin, a dietary flavonoid found in citrus fruits, has shown several neuroprotective and pharmacological properties.Objectives: This study was aimed to assess the protective effects of naringenin against methamphetamine-induced dopaminergic cell death.Methods: Before exposure to methamphetamine, human neuroblastomaSH-SY5Y cells were either pretreated or not treated (controls) with naringenin. Cell viability, level of oxidative stress markers, and expression of some genes involved in apoptosis and autophagy processes were then assessed using MTT, ROS, and MMP assays, and qRT-PCR and Western blotting techniques.Results: Naringenin pretreatment significantly enhanced cell viability following methamphetamine exposure (p < .01). It significantly decreased ROS levels (p < .001), preserved mitochondrial membrane potential, and moderated upregulation of apoptotic (CytC, Casp3, and Bax) and autophagic genes (Beclin-1, and LC-3) and down-regulation of Bcl-2 as an anti-apoptotic gene. Similar naringenin-mediated patterns were observed for cytochrome C and caspase 3 proteins.Conclusion: Naringenin administration can be considered for treating the neurotoxic effects of methamphetamine.

Background: Rural and frontier communities face high rates of opioid use disorders (OUDs). In 2021, the Rural Addiction Implementation Network (RAIN) sought to establish a rural hospital/clinic-system practice-based research network (RH-PBRN) to facilitate implementation of evidence-based addiction-related prevention, treatment, and recovery (PTR) services to reduce the morbidity of OUD and substance use disorder (SUD) in rural communities.Objective: To describe the goals and implementation of PTR activities of RAIN, a novel RH-PBRN.Methods: RAIN identified teams of external/internal facilitators at four rural hospitals/clinic-networks to achieve at least 15 PTR activities involving OUD and other SUDs. RAIN utilized an implementation-facilitation approach: facilitators assessed the implementation environment and promoted interventions to overcome barriers to PTR implementation. Other interventions included site visits, community of learning calls, and e-communication. RAIN assessed and recorded facilitators and barriers to implementation, milestone attainment, and outcomes of PTR activities. At 18 months, we queried facilitators about the fidelity and implementation of RAIN activities.Results: RAIN established an HP-PBRN in four sites (Idaho, Montana, Utah, and Wyoming). Within the HP-PBRN, 20 PTR activities were established (p = 7, T = 10, R = 3; range 3-7 per site). Barriers to implementation of PTR activities included competing clinical demands, especially due to COVID-19, lack of dedicated effort for staff at sites, and stigma of addiction and its treatment. Facilitators of implementation included the use of trained expert facilitators and communication between the sites.Conclusions: RAIN implemented 20 addiction-related PTR activities in four rural hospitals/clinic-networks. RAIN's intervention model could be replicated to address addiction-related harms in other rural communities.

Background: The concurrence of homelessness and alcohol use disorder (AUD) has negative consequences in affected individuals. Managed alcohol programs (MAPs), a harm reduction strategy based on providing regular doses of alcohol to individuals with AUD, have emerged as a potential solution to reduce alcohol-related harms.Objectives: This study examined the impact of a MAP implemented in Barcelona on patterns of alcohol and other psychoactive substance use, health, and quality of life among people who use drugs and were experiencing homelessness. The research also incorporated a gender perspective and focused on individuals who had accessed a residential center.Methods: A descriptive qualitative design was used, employing semi-structured interviews with eight participants who were enrolled in the MAP (three women, five men) and four program professionals. Thematic analysis was used to analyze the resulting data.Results: The domains guiding the study appeared as outcome themes: patterns of use of alcohol and other substances, health, quality of life and impact on female-identified participants. Participants reported improved health due to reduced consumption of alcohol and other substances, better anxiety management, and reconnection to health services. The participants reported enhanced quality of life, including feeling safer, and better use of time, which had been spent on meeting their basic needs. Women reported that a key benefit of the program was living in a sexism-free environment.Conclusion: These results appear to demonstrate that harm reduction strategies prioritizing basic needs and adopting a gender-sensitive perspective can positively impact the health and quality of life of people experiencing homelessness with AUD.

Background: Rural areas in the United States have been severely impacted by recent rises in substance use related mortality and psychosocial consequences. There is a dearth of treatment resources to address substance use disorder (SUD). Rural recovery houses (RRH) are important services that provide individuals with SUD with an environment where they can engage in recovery-oriented activities, but dropout rates are unacceptably high, and evidence-based interventions such as contingency management (CM) may reduce dropout and improve outcomes for RRH residents. In this paper, we describe the results of a national convening of experts that addressed important issues concerning the implementation of CM within the context of RRHs.Methods: Twelve experts (five female) in the areas of CM, RRH and rural health participated in a one-day facilitated meeting that used nominal group technique to identify expert consensus in three areas as they pertain to RRH: (a) facilitators and barriers to CM implementation, (b) elements necessary for successful program building based on group feedback, and (c) recommendations for future implementation of CM.Results: Several RRH- and system-level barriers and facilitators to implementing CM were identified by the panel, and these were categorized based on the level of importance for and ease of implementation. CM funding, staff and resident buy-in, set policies, education on CM, and consistent fidelity to CM procedures and tracking were identified as important requirements for implementing CM in RRH.Conclusions: We provide recommendations for the implementation of CM in RRH that may be useful in this context, as well as more broadly.

Background: Opioid-related overdoses significantly contribute to mortality in pregnancy and the postpartum period. Few studies report risk factors predisposing pregnant and postpartum patients with opioid use disorder (OUD) to overdose.Objective: This scoping review aims to describe the risk factors predisposing pregnant and postpartum patients with OUD to overdose.Method: Included studies identified pregnant and/or postpartum patients with OUD and differentiated between those who experienced overdose and those who did not. Of the 1060 articles, 8 met the criteria, examining 90,860 pregnant and postpartum patients with OUD.Results: Consistent use of medications for OUD (MOUD) during pregnancy and the postpartum period was the most frequently identified factor reducing overdose risk. Critical times of heightened overdose risk include the first trimester and the 7-12-month postpartum period. Pregnancy complications, such as stillbirth, severe maternal morbidity, preterm birth, and cesarean delivery, also increase risk. Opioid overdose is associated with being houseless, incarcerated, young, unmarried, publicly insured, not graduating high school, co-occurring substance use disorders, and inadequate prenatal care. Legislative changes, such as not classifying OUD in pregnancy as "child abuse" and increasing Medicaid reimbursement for Screening, Brief Intervention, and Referral to Treatment programs, are crucial to reducing risk. The impact of race and the influence of co-occurring psychiatric disorders was inconsistently reported.Conclusion: This scoping review identifies significant risk factors for opioid overdose in pregnant and postpartum patients. Improving access through enhanced Medicaid reimbursement, non-punitive reporting policies, and non-stigmatized care are keys to reducing overdose.

Background: Alcoholic liver disease (ALD) significantly contributes to global morbidity and mortality. The role of inflammatory cytokines in alcohol-induced liver injury is pivotal yet not fully elucidated.Objectives: To establish a causal link between inflammatory cytokines and ALD using a Mendelian Randomization (MR) framework.Methods: This MR study utilized genome-wide significant variants as instrumental variables (IVs) for assessing the relationship between inflammatory cytokines and ALD risk, focusing on individuals of European descent. The approach was supported by comprehensive sensitivity analyses and augmented by bioinformatics tools including differential gene expression, protein-protein interactions (PPI), Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis, and analysis of immune cell infiltration.Results: Our findings reveal that increased levels of stem cell growth factor beta (SCGF-β, beta = 0.141, p = .032) and interleukin-7 (IL-7, beta = 0.311, p = .002) are associated with heightened ALD risk, whereas higher levels of macrophage inflammatory protein-1α (MIP-1α, beta = -0.396, p = .004) and basic fibroblast growth factor (bFGF, beta = -0.628, p = .008) are linked to reduced risk. The sensitivity analyses support these robust causal relationships. Bioinformatics analyses around inflammatory cytokine-associated SNP loci suggest multiple pathways through which cytokines influence ALD.Conclusion: The genetic evidence from this study convincingly demonstrates that certain inflammatory cytokines play directional roles in ALD pathogenesis. These findings provide insights into the complex biological pathways involved and underscore the potential for developing targeted therapies that modulate these inflammatory responses, ultimately improving clinical outcomes for ALD patients.

Background: Amid the national opioid epidemic, it is important to assess trends in opioid prescriptions. Long-acting opioids (LAOs) are of particular interest as they are among the most intensely misused prescription opioids. Moreover, understanding geographic trends in opioid prescriptions may help identify state-level variations, illustrating state-specific disparities.Objectives: The study aims to determine geographic trends in overall and LAO prescriptions under Medicaid and Medicare Part D from 2013 to 2021.Methods: We used data from the Centers for Medicare & Medicaid Services on opioid prescriptions from 2013 to 2021. The opioid prescribing proportion was calculated as the number of opioid claims divided by the total number of overall drug claims. The LAO prescribing proportion was calculated as number of LAO claims divided by total opioid claims.Results: Despite a general decrease nationwide, Medicaid opioid prescribing proportions increased in Iowa, Montana, and Virginia. There was an increasing trend in the national-level Medicaid LAO prescribing proportion from 2017 to 2021, with a 14.1% point increase (p for the annual percent change [APC]<0.05). For Medicare Part D, the overall prescribing proportions fell by 1.7% points from 2013 to 2021, while the LAO prescribing proportion fell by 3% points from 2016 to 2021 (p for APC < .05).Conclusions: The increasing trends in national-level Medicaid LAO prescribing and Medicaid opioid prescribing in Iowa, Montana, and Virginia are concerning, and have implications for clinical opioid prescribing. The decreasing trends in Medicare Part D may reflect ongoing efforts in opioid prescription management.

Background: Longitudinal Measurement Invariance (LMI) is critically important to evaluate changes in alcohol expectancies over time. However, past research has not explored the longitudinal properties of the Spanish Expectancy Questionnaire Short Form (EQ-SF).Objectives: To examine the reliability, sources of validity (structural, invariance across sex, and concurrent validity), and LMI of the Spanish EQ-SF among young adults who engage in binge drinking.Methods: Participants (n = 279; 48.4% female) completed the EQ-SF and, two months later, completed it again along with measures of alcohol use, drinking motives, and protective behavioral strategies (PBS). We performed confirmatory factor analysis for structural validity and measurement invariance analysis for longitudinal and sex stability.Results: The eight-factor intercorrelated model (i.e. social facilitation, fun, sexual disinhibition, tension reduction, antisocial effects, negative emotional states, negative physical effects, and cognitive impairments) provided the best fit (χ2(df) = 497.29(224), CFI = .962, RMSEA = .064, SRMR = .049). This model was invariant across sex and time. Reliability coefficients (Ordinal alpha) for each dimension were consistently strong at both time points (from .72 to .93 at T1 and .73 to .91 at T2). Positive alcohol expectancies at baseline were positively related to alcohol use and drinking motives and negatively related to PBS at follow-up, demonstrating predictive validity.Conclusion: Our results support the temporal invariance of the EQ-SF scores among Spanish young adults who engage in binge drinking. The evidence supports the suitability of this measure for accurately assessing changes in alcohol expectancies over time in interventions aimed at preventing binge drinking in young adults.
