Review: Genetic and environmental risk factors for alcohol use disorders in American Indians and Alaskan Natives

Brain regulation training improves emotional competences in patients with alcohol use disorder

Alcohol use disorder (AUD) is defined as the impaired ability to stop or control alcohol use despite adverse social, occupational, or health consequences and still represents one of the biggest challenges for society regarding health conditions, social consequences, and financial costs, including the high relapse rates after traditional alcohol rehabilitation treatment. Especially, the deficient emotional competence in AUD is said to play a key role in the development of AUD and hinders the interruption of substance compulsion, often leading to a viscous circle of relapse. Although the empirical evidence of a neurophysiological basis of AUD is solid and increases even further, clinical interventions based on neurophysiology are still rare for individuals with AUD. This randomized controlled trial investigates changes in emotional competences, alcohol-related cognitions, and drinking behavior before and after an established alcohol rehabilitation treatment (control group: nCG = 29) compared to before and after an optimized, add-on neurofeedback (NF) training (experimental group: nEG = 27). Improvements on the clinical-psychological level, i.e. increases in emotional competences as well as life satisfaction, were found after the experimental electroencephalography (EEG) NF training. Neurophysiological measurements via resting-state EEG indicate decreases in low beta frequency band, while alpha and theta bands remained unaffected.

Psychometric Properties of Controlled Oral Word Association (COWA) Test and Associations With Education and Bilingualism in American Indian Adults: The Strong Heart Study

The Controlled Oral Word Association (COWA) test is used to assess phonemic fluency and executive function. Formal validation of test scores is important for accurate cognitive evaluation. However, there is a dearth of psychometric validation among American Indian adults. Given high burden of dementia risk and key contextual factors associated with cognitive assessments, this represents a critical oversight. In a large, longitudinal population-based cohort study of adult American Indians, we examined several validity inferences for COWA, including scoring, generalization, and extrapolation inferences, by investigation of factor structure, internal consistency, test-retest reliability, and differential test functioning. We found adequate unidimensional model fit, with high factor loadings. Internal consistency reliability and test-retest reliability were 0.88 and 0.77, respectively, for the full group. COWA scores were lowest among the oldest, lowest education, bilingual speakers; group effects for sex and bilingual status were small; age effect was medium; and education effect was largest. However, Wide Range Achievement Test (WRAT) score effect was stronger than education effect, suggesting better contextualization may be needed. These results support interpretation of total COWA score, including across sex, age, or language use strata.

An Updated Narrative Review on the Role of Alcohol Among Indigenous Communities

Purpose of Review

The role of alcohol varies considerably among Indigenous Peoples and is the backdrop of persistent stereotypes despite decades of research. This paper provides an updated narrative review on the alcohol literature among Indigenous communities, highlighting recent studies published since 2017.

Recent Findings

We examined published literature involving alcohol use rates, including abstinence; risk and protective factors; treatment; and recovery, as well as future directions for alcohol prevention and intervention efforts with Indigenous communities.

Summary

Evidence-based alcohol use prevention, intervention, and recovery strategies with Indigenous communities are outlined. Recommendations are provided for researchers, health providers, and public policy advocates to address and better understand alcohol use, treatment, prevention, and recovery among Indigenous Peoples. Specific recommendations include using community-based participatory research strategies and harm reduction approaches to prevent and treat alcohol use problems with Indigenous communities. Future research is needed to elucidate mechanisms of resilience and recovery from Alcohol Use Disorder and possible shifts in perceptions of alcohol use for Indigenous Peoples.

Association of racism and substance use treatment with belief in the myth of an American Indian/Alaska Native biological vulnerability to alcohol problems

OBJECTIVES

Belief in an American Indian/Alaska Native (AIAN) specific biological vulnerability (BV) to alcohol problems is associated with worse alcohol outcomes among AIANs. Despite a notable lack of evidence that biogenetic factors play a greater role in the development of alcohol problems among AIANs than other groups, many people still believe this myth. Consistent with theory and evidence that greater experiences with discrimination leads to the internalization of stereotypes and oppression, we hypothesized that greater perceived racial discrimination (racism) would be associated with greater BV belief, but that having a stronger ethnic identity would weaken this association. We also examined whether previous substance use treatment as well as participation in Alcoholics Anonymous (AA) or Narcotics Anonymous (NA) was associated with BV belief.

METHOD

Participants were 198 reservation-dwelling AI adults with a substance use problem who completed a survey as part of a larger community-based participatory study.

RESULTS

A multiple regression analysis revealed that greater systemic racism was associated with greater belief in a BV; this association was not moderated by ethnic identity. Greater interpersonal racism was also associated with greater BV belief-but only among those low in ethnic identity. A regression analysis revealed that previous treatment, AA, and NA participation were not associated with BV belief.

CONCLUSIONS

Greater systemic and interpersonal racism were associated with belief in a BV, and greater ethnic identity buffered the association between interpersonal racism and BV belief. This suggests that both combatting racism and fostering positive ethnic identity may help to lessen BV belief. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Depression Symptoms, Perceived Stress, and Loneliness During the COVID-19 Pandemic Among Diverse US Racial-Ethnic Groups

Introduction

Studies have reported increases in psychological distress during the COVID-19 pandemic. This study aimed to estimate associations between race-ethnicity and psychological distress during the COVID-19 pandemic among nationally representative samples of all major racial-ethnic groups in the United States.

Methods

We conducted a nationally representative cross-sectional survey between December 2020 and February 2021 of Asian, black/African American, Latino (English and Spanish speaking), American Indian/Alaska Native, Native Hawaiian/Pacific Islander, white, and multiracial adults (n=5500). Distress measures included: anxiety-depression (Patient Health Questionnaire-4 [PHQ-4]), stress (modified Perceived Stress Scale), and loneliness-isolation (frequency felt lonely and isolated). Multinomial logistic regression models estimated associations between race-ethnicity and psychological distress, adjusting for demographic and health characteristics.

Results

Overall, 23.7% reported moderate/severe anxiety-depression symptoms, 34.3% reported moderate/severe stress, and 21.3% reported feeling lonely-isolated fairly/very often. Compared with white adults and adjusting for covariates, the prevalence of moderate/severe anxiety-depression was significantly lower among Asian (adjusted odds ratio [aOR]=0.44, 95% confidence interval [CI]=0.34-0.58), black (aOR=0.49, 95% CI=0.38-0.63), English-speaking Latino (aOR=0.62, 95% CI=0.45-0.85), Spanish-speaking Latino (aOR=0.31, 95% CI=0.22-0.44), and Native Hawaiian/Pacific Islander (aOR=0.66, 95% CI=0.49-0.90) adults. Similar trends were seen for moderate/severe stress and feeling lonely-isolated fairly/very often. Worse distress profiles of American Indian/Alaska Native and multiracial adults were attenuated after adjustment.

Conclusions

Minoritized groups tended to have less distress than white adults. Collective experiences of cumulative disadvantage could engender shared resiliency/normalization among these groups.

Non-pharmacotherapeutic Management of Alcohol Use Disorder in the Alaska Native Population: A Narrative Review

Alcohol use disorder (AUD) is a leading preventable cause of death in the United States and has had a greater health impact on Alaska Natives than on any other racial group. To date, AUD in these communities has had wide-reaching negative impacts contributing to high rates of suicide, homicide, and accidents. A variety of genetic, experiential, social, and cultural factors have been associated with this trend. For decades, the Alaska Native subgroup has received inadequate treatment. The purpose of this review is to evaluate current trends in effective interventions and to help answer the question: What may comprise a successful non-pharmacotherapeutic interventional strategy to treat and prevent AUD in Alaska Natives? A database literature search was performed in September 2022 using the PubMed library. Search terms included (alcohol use disorder) AND ((Alaska OR Alaskan) Native). Inclusion criteria included full-text articles, a focus on specific non-pharmacotherapeutic treatment strategies, and a publication date after 2005. Studies that did not evaluate non-pharmacotherapeutic interventions, evaluated a population other than Alaska Natives, evaluated a disorder other than AUD, were written in a language other than English, or were editorials or opinion pieces were excluded. The selected studies were assessed for bias utilizing the Newcastle-Ottawa Scale (NOS). Twelve studies were included in this review. This review found that early social network intervention, incentive-driven programs, culturally-driven programs, and motivational interviewing are promising non-pharmacotherapeutic interventions in the treatment of AUD in Alaska Native communities. Evidence suggests that a shift in focus to the accentuation of protective factors and the mitigation of isolation as a risk factor, rather than on the reduction of more intractable risk factors, may be associated with improved outcomes in treating AUD. The literature also suggests that successful prevention strategies should be driven by indigenous knowledge and grounded in community and culture. This study has its limitations. These include a lack of direct comparisons between studies, a lack of pooled statistical analysis or synthesis, and a lack of quantitative analysis. Instead, the majority of data is gathered from more bias-prone cross-sectional studies and, thus, should be used to provide insight into potential risk factors and non-pharmacologic therapies effective in this population rather than as strong evidence in favor of one therapeutic regimen over another. For this, there is a need for more clinical trials evaluating treatments for AUD in this population. This review received support from the University of South Florida Department of Psychiatry. There were no sources of funding for this work from any institution. There are no competing financial or non-financial interests that may be interested in this work. This review is not registered.

Analysis of polymorphic variants in the ADH7 gene in alcohol abusers and addicts

Environmental and genetic (in approximately 50%) factors are responsible for the development of alcohol abuse and dependence. The main genes responsible for the risk of harmful alcohol consumption are the genes encoding the enzymes of ethanol metabolism in the human body. Ethyl alcohol is oxidized to acetaldehyde by alcohol dehydrogenases found in the liver (ADH1B, ADH1C and ADH4) and stomach (ADH7). Gastric metabolism of ethanol is able to reduce the amount of alcohol reaching the bloodstream by up to 10% of the dose taken. ADH7 gene variations could be associated as the risk of developing alcohol abuse and dependence. Aim of the study: Analysis of tag SNPs in the ADH7 gene and determination of the relationship between those variants and the risk of developing alcohol abuse and dependence in the Polish population. Materials and methods: Blood samples from 159 autopsies from alcohol abusers and/or addicts and 201 buccal swabs taken from controls. Genotyping was performed using the Real Time PCR method with TaqMan probes on 3 tag SNPs: rs284786, rs1154470 (within the ADH7 gene) and rs7690269 (from the intergenic region). The obtained genotypes were randomly verified by Sanger sequencing. Results and conclusions: The results of the performed statistical analyses of the obtained genotypes did not confirm the relationship between the above-mentioned variants and a risk of developing problems with alcohol consumption, based on samples from the Polish population. Key words: alcohol addiction, alcohol abuse, alcohol dehydrogenases, gastric dehydrogenase, ADH7 Analiza wariantów polimorficznych w genie ADH7 u osób nadużywających i uzależnionych od alkoholu Nadużywanie i uzależnienie od alkoholu zależy zarówno od czynników środowiskowych, jak i w około 50% czynników genetycznych. Głównymi genami, które są odpowiedzialne za zwiększone ryzyko rozwoju szkodliwego spożywania alkoholu są geny kodujące enzymy rozkładu etanolu w organizmie ludzkim. Alkohol etylowy jest utleniany do aldehydu octowego przez dehydrogenazy alkoholowe występujące w wątrobie (ADH1B, ADH1C i ADH4) oraz żołądku (ADH7). Metabolizm żołądkowy etanolu jest w stanie obniżyć jego ilość trafiającą do krwiobiegu nawet do 10% przyjętej dawki. Zmiany występujące w genie ADH7 wykazują związek z ilością spożywanego alkoholu, a także ryzykiem rozwoju nadużywania i uzależnienia od tej substancji. Cel pracy: Analiza zmian znacznikowych w genie ADH7 i określenie związku wariantów badanego genu z ryzykiem rozwoju nadużywania i uzależnienia od alkoholu w populacji polskiej. Materiały i metody: Materiał do badań stanowiła krew pobrana od 159 denatów, którzy nadużywali i/lub byli uzależnieni od alkoholu oraz 201 wymazów policzkowych od osób kontrolnych z populacji polskiej. Wykorzystując metodę Real Time PCR z sondami TaqMan wykonano genotypowanie w zakresie 3 zmian znacznikowych: rs284786, rs1154470 (w obrębie genu ADH7) i rs7690269 (z regionu międzygenowego). Otrzymane genotypy losowo weryfikowano sekwencjonowaniem metodą Sangera. Wyniki i wnioski: Analiza statystyczna otrzymanych wyników nie potwierdziła związku wybranych wariantów z ryzykiem nadużywania i uzależnienia od alkoholu.

Centering culture in the treatment of opioid use disorder with American Indian and Alaska Native Communities: Contributions from a National Collaborative Board

American Indian/Alaska Native (AI/AN) communities are disproportionally impacted by the opioid overdose epidemic. There remains a dearth of research evaluating methods for effectively implementing treatments for opioid use disorder (OUD) within these communities. We describe proceedings from a 2-day Collaborative Board (CB) meeting tasked with developing an implementation intervention for AI/AN clinical programs to improve the delivery of medications to treat OUD (MOUD). The CB was comprised of Elders, cultural leaders, providers, individuals with lived experience with OUD, and researchers from over 25 communities, organizations, and academic institutions. Conversations were audio-recorded, transcribed, and coded by two academic researchers with interpretation oversight provided by the CB. These proceedings provided a foundation for ongoing CB work and a frame for developing the program-level implementation intervention using a strength-based and holistic model of OUD recovery and wellbeing. Topics of discussion posed to the CB included engagement and recovery strategies, integration of extended family traditions, and addressing stigma and building trust with providers and clients. Integration of traditional healing practices, ceremonies, and other cultural practices was recommended. The importance of centering AI/AN culture and involving family were highlighted as priorities for the intervention.

Measuring Attitudes About Alcohol Misuse and Dependence Among Alaska Native People Within a Tribal Health Care System

OBJECTIVES

Attitudes about alcohol misuse and dependence influence alcohol use and help-seeking behavior. Alaska Native and American Indian (AN/AI) people have higher rates of alcohol-related morbidity and mortality but engage in treatment at lower rates than the general population. No validated instruments exist to assess attitudes of AN/AI people about alcohol misuse and dependence to inform treatment and prevention efforts. This study aimed to develop an instrument to assess public attitudes among AN/AI people of alcohol misuse and dependence.

METHODS

This multiphase, mixed-methods study was conducted at Southcentral Foundation, a tribally owned health system serving 65,000 AN/AI people in Alaska. We conducted focus groups and interviews with health system users, providers, and leaders to adapt the Public Attitudes About Addiction Survey. The adapted instrument was piloted with 200 people. Cognitive interviews and exploratory and confirmatory factor analyses were used to refine the instrument, which were then administered to 777 AN/AI people.

RESULTS

Initial exploratory factor analysis identified 5 factors, including 3 from the original Public Attitudes About Addiction Survey (moral, disease, nature), a combined psychology and sociology factor (psychosocial), and a new factor (environment). A final 4-factor model (psychosocial, moral, disease, nature) with 14 items had good fit with root mean square error of approximation (0.035; comparative fit index = 0.977; Tucker-Lewis index = 0.970; standardized root mean residual = 0.040) and loadings ranging from 0.41 to 0.80.

CONCLUSIONS

This study developed the first instrument to assess AN/AI attitudes about alcohol misuse and dependence. This instrument has potential to inform alcohol-related treatment in AN/AI communities. Future research is warranted to adequately measure place-based contributors salient to AN/AI people.

Harm reduction acceptability and feasibility in a North American indigenous reserve community

AIMS

The present study assessed community and culturally specific alcohol-related harm among North American Indigenous (NAI) individuals, as well as the acceptability and feasibility of harm reduction approaches in one reserve-based NAI community.

METHODS

Participants lived on or near a NAI reserve in Canada. Semi-structured focus groups were conducted with health care workers (N = 8, 75% NAI) and community members (N = 9, 100% NAI). Self-report questionnaires were administered that measured acceptability and feasibility of harm reduction strategies.

RESULTS

Conventional content analysis revealed loss of culture as culturally specific alcohol-related harm. Health care workers rated harm reduction approaches to be acceptable and feasible, while community participants were more mixed. Majority of participants felt that some harm reduction strategies could provide opportunities for individuals who use alcohol to connect to Indigenous culture and traditions. However, there were mixed findings on whether harm reduction strategies are consistent with Indigenous cultural traditions and values.

CONCLUSION

Future research is needed to evaluate potential utility of harm-reduction approaches for NAI communities.

Psychological and social support associations with mortality and cardiovascular disease in middle-aged American Indians: the Strong Heart Study

PURPOSE

Our study examined psychosocial risk and protective features affecting cardiovascular and mortality disparities in American Indians, including stress, anger, cynicism, trauma, depression, quality of life, and social support.

METHODS

The Strong Heart Family Study cohort recruited American Indian adults from 12 communities over 3 regions in 2001-2003 (N = 2786). Psychosocial measures included Cohen Perceived Stress, Spielberger Anger Expression, Cook-Medley cynicism subscale, symptoms of post-traumatic stress disorder, Centers for Epidemiologic Studies Depression scale, Short Form 12-a quality of life scale, and the Social Support and Social Undermining scale. Cardiovascular events and all-cause mortality were evaluated by surveillance and physician adjudication through 2017.

RESULTS

Participants were middle-aged, 40% male, with mean 12 years formal education. Depression symptoms were correlated with anger, cynicism, poor quality of life, isolation, criticism; better social support was correlated with lower cynicism, anger, and trauma. Adjusted time-to-event regressions found that depression, (poor) quality of life, and social isolation scores formed higher risk for mortality and cardiovascular events, and social support was associated with lower risk. Social support partially explained risk associations in causal mediation analyses.

CONCLUSION

Altogether, our findings suggest that social support is associated with better mood and quality of life; and lower cynicism, stress, and disease risk-even when said risk may be increased by comorbidities. Future research should examine whether enhancing social support can prospectively reduce risk, as an efficient, cost-effective intervention opportunity that may be enacted at the community level.

Focusing on Racial, Historical and Intergenerational Trauma, and Resilience: A Paradigm to Better Serving Children and Families

Research across populations demonstrates that intergenerational trauma can have lasting biological, psychological, and social consequences and affects groups of individuals in different ways. An appreciation of intergenerational trauma as experienced in diverse populations is important not only for understanding vulnerabilities and risk but also for cultivating opportunities for posttraumatic growth and healing. Understanding the contexts of trauma for children and families and the unveiling of structural inequities, both past and present, offers the opportunity to address these in using clinical and systems of care approaches in the public health spheres.

Multi-omics integration reveals the hepatoprotective mechanisms of ursolic acid intake against chronic alcohol consumption

PURPOSE

Alcoholic liver disease (ALD) is a major health issue globally. In addition to pharmacotherapy, dietary support is also regarded as reliable strategy for ALD management. As a widely distributed natural constituent within edible plants, the present study aims to investigate the hepatoprotective effects of ursolic acid (UA) against ALD and also to deepen insights into the underlying targets and mechanisms comprehensively.

METHODS

The hepatoprotective activity of UA against chronic alcohol-induced liver injury was investigated on Lieber-DeCarli liquid diet-based mouse model. In-depth RNA-seq transcriptomics and TMT-based proteomics analyses were conducted in parallel. Data integration as well as bioinformatics analysis were also performed to unravel the targets and mechanisms associated with the hepatoprotective activity of UA intake against alcoholic liver injury comprehensively.

RESULTS

The serum biomarkers and pathological characteristics indicated the hepatoprotective effects of UA intake on alcoholic liver injury. 567 target genes and 377 target proteins related to the hepatoprotective activity of UA were identified in transcriptomics and proteomics analysis respectively, most of which were associated with function of cellular process, cell part and binding. After data integration, 56 co-regulated targets, including ADH4, CYP450 enzymes, NQO1, apolipoproteins, glutathione-S-transferase, etc. which were consistently modulated on both mRNA and protein levels were identified. These co-regulated targets were found to be correlated with 70 KEGG pathways led by carcinogenesis, retinol metabolism and CYP450 metabolism pathways.

CONCLUSION

UA intake ameliorated chronic alcohol-induced liver injury. Given the role of the co-regulated targets in ALD and the bioinformatics analysis results, CYP450-, glutathione and redox homeostasis-dependent antioxidation, promotion of lipid transport, and restoration of ethanol metabolic capacity are the potentially underlying mechanisms. This information will further deepen our insights into the hepatoprotective effects of UA-rich edible plants, and provide us valuable instruction for ALD management.

Factors That Influence Substance Use Among American Indian/Alaskan Native Youth: A Systematic Mixed Studies Review

BACKGROUND

The American Indian/Alaskan Native (AI/AN) mortality rate from illicit drug use was 22.7%, double that of the general population between 2007 and 2009. Fifteen percent of AI/AN youth reported receiving treatment for substance use compared with 10% of non-AI/AN peers.

OBJECTIVE

The purpose was to explore the factors that influence substance use among AI/AN youth.

METHOD

We performed a systematic review using a results-based convergent synthesis design. Eight electronic databases were searched for articles published between 2014 and 2019 using the search terms "Native American youth," "Native American adolescent," "Native Youth," "substance use," "substance misuse," and "substance abuse." The Mixed Methods Appraisal Tool was used to appraise the studies.

RESULTS

Forty-seven studies met the inclusion criteria (44 quantitative, one qualitative, and two mixed-methods studies). The results were organized using the ecological systems model and included evaluation of both protective and risk factors related to AI/AN youth substance use. Three system levels were found to influence substance use: individual, micro- and macrosystems. The individual systems-level coping mechanisms played a key role in whether AI/AN youth initiated substance use. Family, school, and peer factors influence the microsystem level. At the macrosystem level, community environmental factors were influential.

CONCLUSION

The major factor linking all the systems was the influence of a connected relationship with a prosocial adult who instilled future aspirations and a positive cultural identity. Findings of this systematic mixed studies review will assist in intervention development for AI/AN youth to prevent substance misuse.

The Prevalence of Adverse Childhood Experiences, Body Shame, and Revision Request Rate in 218 Plastic Surgery Patients: What Drives Postoperative Dissatisfaction?

BACKGROUND

What drives patients who are unhappy despite good results? Adverse childhood experiences are common, can impair adult health, and can cause body shame. Neither adverse childhood experiences nor body shame has been studied in surgical patients. The authors report adverse childhood experience prevalences in a plastic surgical population and investigate associations from adverse childhood experiences to body shame and to postoperative dissatisfaction.

METHODS

Two hundred eighteen consecutive patients (86 percent aesthetic and 14 percent reconstructive) completed the Adverse Childhood Experiences Survey and the Experience of Shame Scale. A one-sample test of proportions, logistic regression, and mediation analysis assessed outcomes.

RESULTS

Compared to the Kaiser/Centers for Disease Control and Prevention medical population, our patients had higher overall adverse childhood experience prevalences (79.8 percent versus 64 percent), emotional abuse (41 percent versus 11 percent), emotional neglect (38 percent versus 15 percent), family substance abuse (36 percent versus 27 percent), and family mental illness (29 percent versus 19 percent, all p < 0.001). Fifty-two percent of our patients had body shame. Adverse Childhood Experiences score predicted body shame (OR, 1.22; p = 0.003). Compared to unshamed patients, body shame was associated with more adverse childhood experiences (85 percent versus 72 percent), higher median Adverse Childhood Experiences score (3.5 versus 2), more cosmetic operations (three versus zero), more health problems (three versus two), higher antidepressant use (39 percent versus 19 percent), substance abuse history (16 percent versus 5 percent), and demands for additional pain medication (18 percent versus 5 percent). Body shame predicted requests for surgical revision (49 percent versus 17 percent; OR, 4.61; all p ≤ 0.0001).

CONCLUSIONS

Adverse childhood experience were common in our patients. Adverse Childhood Experiences score predicted body shame, which predicted revision requests. If body shame preceded and drove surgery, revision requests were likely. Patients desiring revisions had recognizable characteristics.

Belief in the myth of an American Indian/Alaska Native biological vulnerability to alcohol problems among reservation-dwelling participants with a substance use problem

BACKGROUND

Belief in the myth of an American Indian/Alaska Native (AIAN)-specific biological vulnerability (BV) to alcohol problems is associated with worse alcohol outcomes among AIAN college students who drink, despite also being associated with greater attempts to reduce drinking. This study examined the association of belief in a BV with alcohol use among reservation-dwelling AI adults with a substance use problem.

METHODS

Participants (n = 141) who drank alcohol in the past 90 days were selected from a larger AI sample who self-identified as having a substance use problem. Moderated-mediation analyses examined whether belief in a BV was positively associated with alcohol- and substance use-related consequences and whether self-efficacy and craving mediated the association of belief in a BV with alcohol use.

RESULTS

Among participants who reported using alcohol but not hard drugs (e.g., methamphetamine, opioids), greater belief in a BV was associated with more drinking days, which in turn was associated with greater alcohol-related consequences. Among participants who used alcohol only, belief in a BV was also significantly associated with greater craving, and in turn with more drinking days. Among individuals who used both alcohol and hard drugs, greater belief in a BV was associated with fewer drinking days, but was not significantly associated with substance use-related consequences. No association was found between belief in a BV and self-efficacy to avoid alcohol or drug use.

CONCLUSIONS

Among individuals who use only alcohol, belief in a BV may contribute to more drinking days and greater alcohol-related consequences through its association with greater craving. This study provides further evidence of the potential harm of internalizing the belief that being AIAN contributes to the risk for alcohol problems, a notion that lacks scientific evidence despite decades of research. The findings highlight the importance of combating societal myths regarding AIAN peoples and the internalization of these stereotypes.

Substance use disorder and homelessness among American Indians and Alaska Natives in California

American Indian and Alaska Native (AIAN) communities have higher rates of substance use than other racial and ethnic groups. Substance use disorder (SUD) is tied to the increased risk of experiencing homelessness. National policies have also led to the disproportionate rates of homelessness among AIAN communities. However, specific experiences related to the occurrence of SUD and homelessness among AIAN in California, as well as seeking and accessing SUD treatment, are not well understood. This study explored potential SUD risk and resilience factors for AIANs experiencing homelessness and their experiences when seeking services for SUD. Nineteen interviews were conducted in northern, central, and southern California. Thematic analysis was used for these data. The five primary codes were: (1) risk factors for SUD, (2) resilience related to SUD service seeking, (3) services available, (4) barriers accessing services, and (5) services needed. Based on the results, themes for risk were trauma, mental health, and community conditions. Themes for resilience were identified at individual and community levels and included personal motivation and community support and inclusiveness. Themes for services available were limited knowledge about service types and services' location. The themes for barriers accessing services were identified at internal and external levels, and included lack of readiness and transportation challenges, respectively. Themes for services needed included continuum of care, integrated care, and culturally sensitive services. Findings highlight the importance of addressing the potential risk factors and service needs of AIANs experiencing homelessness to provide comprehensive and culturally sensitive services to reduce substance use.

Dietary Ursolic Acid Prevents Alcohol-Induced Liver Injury via Gut-Liver Axis Homeostasis Modulation: The Key Role of Microbiome Manipulation

Ursolic acid (UA), a natural triterpenoid widely distributed within fruits and edible plants, has been proven to relieve alcoholic liver disease (ALD). However, the mechanisms involved largely remain unclear. This study investigated whether the beneficial effects of UA on ALD could be related to gut-liver axis (GLA) modulation. Special attention was paid to the contribution of gut microbiome manipulation. UA ameliorated intestinal oxidative stress and barrier dysfunction induced by alcohol. As a consequence of gut leakiness amelioration, the related endotoxemia-mediated liver toll-like receptor 4 pathway induction and the subsequent reactive oxygen species overproduction were reverted. UA also counteracted alcohol-induced gut dysbiosis. A fecal microbiota transplantation study indicated that liver injury as well as ileum oxidative stress and gut barrier dysfunction of recipient mice were partly ameliorated as a result of microbiome remodeling. These results suggest that dietary UA alleviates ALD through GLA homeostasis modulation. Gut microbiome manipulation contributes to the hepatoprotective activity and GLA modulating effect of UA.

Antisocial Personality Disorder Among Patients in Treatment for Alcohol Use Disorder (AUD): Characteristics and Predictors of Early Relapse or Drop-Out

Background

Patients with alcohol use disorders (AUD) vary significantly in many clinically important characteristics making them a heterogenous group. AUD patients with comorbid antisocial personality disorder (ASPD) form an important sub-group, and studies indicate that these patients may have poorer treatment outcomes. Therefore, we aimed to investigate the characteristics of AUD inpatients with comorbid ASPD and identify predictors of early relapse or treatment drop-out in these patients.

Methods

In a longitudinal study of AUD patients (n = 113; 30 females; aged 27 to 72 years) in treatment at three residential rehabilitation clinics in Norway, we used interviews and self-report questionnaires to collect data on alcohol use, mental health, and trauma experience. In addition, we assessed biochemical parameters. The patients were followed up at 6 weeks to identify early relapse or drop-out.

Results

Prevalence of ASPD among AUD patients was 15%. AUD patients with comorbid ASPD were exclusively male, of younger age, and reported more childhood trauma, and adult attention-deficit-hyperactivity-disorder symptoms. They reported more hazardous drinking behavior and more often had dependence on substances in addition to alcohol. The presence of ASPD did not predict early relapse or drop-out. However, early relapse or drop-out in ASPD patients was associated with childhood and adult trauma, younger age of drinking debut, and higher baseline prolactin levels.

Conclusion

AUD patients with ASPD had different clinical characteristics to other AUD patients and they had specific predictors of early relapse or drop-out. Our findings indicate that the early relapse or drop-out among AUD patients with ASPD may be attributed to environmental and possibly biological vulnerability. However, further studies with larger sample size are warranted to confirm these preliminary associations.

Perceptions of alcohol misuse among Alaska native health care system stakeholders: A qualitative exploration

Although alcohol misuse is a priority for health care systems serving Alaska Native and American Indian (ANAI) people, stakeholders' perceptions of misuse are understudied. Patients (n = 34), providers (n = 20), and leaders (n = 16) at a Tribally owned and operated health care system reported that alcohol misuse results from the interaction of factors, including colonization, structural factors, social alienation, social norms about overdrinking introduced at the time of colonizing contact, coping with emotions, and beliefs about ANAI people and alcohol. Childhood exposure to alcohol misuse leads some ANAI people to avoid alcohol altogether, shedding light on the high levels of abstinence observed in ANAI communities.

Health Risk Factors in American Indian and Non-Hispanic White Homeless Adults

Objectives: American Indians (AIs) are over-represented among homeless populations, but are understudied regarding their unique risk and resilience factors relative to non-Hispanic white (NHW) adults experiencing homelessness. In the current study, we aimed to address this gap. Methods: We recruited participants (108 AIs and 307 NHWs) from 6 homeless serving agencies in Oklahoma City, OK. Participants completed standard assessments of health, health behaviors, including alcohol and drug use, readiness to change endorsed health behaviors (eg, unsafe sex, fruit and vegetable intake, happiness with weight, physical activity), sleep location and quality, personal victimization, and discrimination. Results: Compared to NHWs, AIs endorsed greater alcohol use problems and were more likely to report having been arrested/booked for disorderly conduct or public drunkenness; however, AIs were less likely to report smoking cigarettes and reported greater readiness to change unsafe/unprotected sexual behaviors. Furthermore, compared to NHWs, AIs reported experiencing greater discrimination and were more likely to report sleeping outside or on the streets, versus in shelters; however, AIs reported fewer days of inadequate sleep. Conclusions: Findings suggest AI-specific risk and resilience factors for homelessness. This information can aid in treatment, service, and housing planning for this under-studied group who experiences some of the greatest health disparities.

Understanding the link between racial trauma and substance use among American Indians

Historians and scholars from various disciplines have documented the pervasive influence of racism on American society and culture, including effects on the health and well-being of American Indian (AI) people. Among the many health problems affected by racial discrimination and oppression, both historical and current, are substance use disorders. Epidemiological studies have documented greater drug and alcohol-related morbidity and mortality among AI/AN Alaska Natives compared to other ethnic groups, and culturally appropriate, effective interventions are sorely needed. We collected, as part of a larger community-based participatory research project to address substance use disparities in rural AI communities, qualitative interview data from 25 AI key informants from a frontier reservation in Montana. Using a semistructured interview guide, we asked participants to discuss their perceptions of the causes of substance use problems and barriers to recovery on the reservation. Although no questions specifically asked about discrimination, key informants identified stress from racism as an important precipitant of substance use and barrier to recovery. As one participant stated: "Oppression is the overarching umbrella for all sickness with drugs and alcohol." Participants also identified historical trauma resulting from colonization as a manifestation of race-based stress that drives behavioral health problems. Findings suggest that interventions for AIs with substance use disorders, and possibly other chronic health problems, may be more effective if they address social determinants of health such as racial discrimination and historical trauma.

Perceptions and Prevalence of Alcohol and Cigarette Use Among American Indian Adults With Type 2 Diabetes

IN BRIEF This study examined community perceptions and prevalence of alcohol use and cigarette smoking among American Indian adults with type 2 diabetes. Results revealed normative rates and perceptions of smoking and negative views and low rates of alcohol use. Participants reported high levels of household indoor smoking and comorbid high-risk drinking and smoking. The high smoking rate among the adult American Indians in this study is especially problematic given the increased risk of cardiovascular problems related to both smoking and type 2 diabetes. The results underscore the importance of considering substance use behaviors and beliefs as a component of overall health and well-being for people with diabetes.

Endorsement of the "firewater myth" affects the use of protective behavioral strategies among American Indian and Alaska Native students

Belief in an American Indian/Alaska Native (AI/AN) specific biological vulnerability (BV) to alcohol problems (aka the "firewater myth") has been found to be associated with worse alcohol outcomes among AI/AN college students who drink, despite also being associated with greater attempts to reduce drinking. In the current study, we examined the associations of belief in a BV and belief that AI/AN people have more alcohol problems with the use of alcohol protective behavioral strategies (PBS) among AI/AN college students. PBS examined, as measured by the Protective Behavioral Strategies Scale-20, included manner of drinking, limiting/stopping drinking, and serious harm reduction strategies. Participants were college students who identified being AI/AN (n = 137) and had drank in the past month, and were selected from a larger multi-site study on PBS. Mediation models revealed that greater belief in a BV and belief that AI/AN people have more alcohol problems were both negatively associated with manner of drinking, which in turn was associated with greater past month alcohol use and alcohol consequences. These beliefs were not significantly associated with other PBS. Consistent with prior research with other student populations, both manner of drinking and limiting/stopping drinking were associated with less alcohol use and all three domains of PBS were directly associated with fewer alcohol consequences. The results suggest that these beliefs regarding AI/AN people and alcohol negatively affect the use of strategies aimed at avoiding drinking behavior that can lead to rapid drinking and a higher blood alcohol content, contributing to alcohol consequences.

A systematic review: Candidate gene and environment interaction on alcohol use and misuse among adolescents and young adults

BACKGROUND AND OBJECTIVES

Youth drinking is a pervasive public health concern with serious negative developmental implications. Candidate gene and environment interaction studies (cGxE) show that environmental effects on drinking behaviors may differ by individuals' genotypes. Yet little is known about whether genetic and environmental effects on drinking behaviors are developmentally specific.

METHODS

This systematic review evaluated 42 cGxE studies of drinking in adolescence and young adulthood.

RESULTS

Although there are mixed findings, studies of cGxE effects involving DRD4, 5-HTTLPR, DRD2, and OPRM1 genotypes showed relatively consistent patterns. The effects of under-controlled environments (eg, low levels of parental monitoring) on early and middle adolescent drinking appeared to differ across DRD2 or OPRM1 genotypes. Effects of alcohol-facilitating environments (eg, heavy drinking peers) on late adolescent and young adult drinking appeared to differ across DRD4 or OPRM1 genotypes. Interactions between 5-HTTLPR genotype with stressful environments (eg, negative life events) were found throughout adolescence and young adulthood, although there were some inconsistencies regarding the risk-conferring allele. There was limited evidence for other cGxE effects due to the small number of studies.

CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE

This review suggests that GxE findings may advance our knowledge regarding which developmentally specific conditions result in the expression of candidate genes that influence youth alcohol use and misuse. However, since a significant number of studies had small sample sizes and most studies had small effect sizes, findings need replication across independent studies with large samples.

Commentary: Perspectives on alcohol-related gene and environment interplay in diverse populations

BACKGROUND AND OBJECTIVES

Racial/ethnic groups comprise more than 20% of the U.S. population, but many experience disproportionately high risk for alcohol misuse, often resulting in higher rates of alcohol-associated consequences. Completion of mapping the human genome has launched rapidly evolving research methods aimed at improved understanding of genetic contribution to disease. Despite decades of research on the influence of genetic and environmental risks on alcohol use disorders and outcomes, few studies have included racial/ethnic subpopulations in sufficient numbers to allow for proper statistical analysis.

METHODS

The papers in this special issue help to elucidate current knowledge on the etiology of genetic and environmental contributors and potential moderators of alcohol use and associated problems among racial/ethnic populations. The lack of racial/ethnic diversity across many genetic studies contributes to challenges in interpretation of findings and eventually applications to precision medicine.

RESULTS

Proposed approaches to overcome disparities in racial/ethnic participant recruitment in genetic studies include methods to address population stratification in allele frequency, improve transparency in subjects' consenting to participate, and engaging interdisciplinary research teams and community involvement to improve recruitment of racial/ethnic minorities.

DISCUSSION AND CONCLUSIONS

The reviews presented underscore various gaps in our knowledge of the genetic influences on alcohol use disorders due to the failure to include racially and ethnically diverse populations in genetic and epigenetic study samples. New directions are suggested to overcome the resulting research challenges and ultimately to inform future personalized intervention approaches for racial/ethnic populations.

SCIENTIFIC SIGNIFICANCE

Inclusion of heterogeneous populations in genomic research will provide a better comprehension of possible unique genetic factors in the broader general population that may be missed due to exclusion of unique and common variants that may be present in racial/ethnic populations.

Conclusion: Special issue on genetic and alcohol use disorder research with diverse racial/ethnic groups: Key findings and potential next steps

BACKGROUND AND OBJECTIVES

This special issue brings together papers focusing on a wide range of topics relevant to the research and understanding of the role of race/ethnicity and genetic variation for the susceptibility of developing an alcohol use disorder (AUD).

METHODS

The key findings from the issue's 10 articles are reviewed and organized here around three topics: I: addictive behaviors and potential environmental influences; II: a focus on four racial/ethnic groups; and III: special methodologies.

RESULTS

Several potential next steps in improving effective research strategies are highlighted: (1) implementing best practices for outreach and community engagement may reduce reluctance to participate; (2) recruiting adequately sized and racially/ethnically diverse samples will require new collaborations with investigators who successfully work in diverse communities; (3) identifying and assessing environmental influences that are both unique to, and common among, racial/ethnic groups may inform preventions for AUD; (4) use of standardized measures will facilitate the generation of larger samples and meta-analysis of research findings; and (5) use of better analytic approaches and experimental methods will improve replication in gene finding research and help advance new areas of research.

CONCLUSIONS

Genetic research of AUD in diverse racial/ethnic populations is advancing. The articles in this issue examined the general theme of including diverse population groups in genetic studies and offered potential strategies for addressing some common problems.

SCIENTIFIC SIGNIFICANCE

Greater inclusion of diverse racial/ethnic populations in this research is important to ensure that the benefits of new knowledge and technology are equally shared. (Am J Addict 2017;26:532-537).

Spatial Epidemiology of Alcohol- and Drug-Related Health Problems Among Northern Plains American Indians: Nebraska and South Dakota, 2007 to 2012

BACKGROUND

Despite high abstinence rates, American Indians experience elevated rates of many alcohol and other drug problems. American Indians also predominantly reside in poor and rural areas, which may explain some observed health disparities. We investigated whether geographic areas including reservations or large American Indian populations exhibited greater incidence of alcohol- and drug-related hospitalizations.

METHODS

We obtained inpatient hospitalization records for 2 Northern Plain states (Nebraska and South Dakota) for the years 2007 to 2012. We constructed zip code counts for 10 categories of hospitalization with diagnoses or injury causation commonly associated with alcohol or drug use. We related these to community sociodemographic characteristics using Bayesian Poisson space-time regression models and examined associations with and without controls for whether each zip code was located within an American Indian reservation.

RESULTS

Controlling for other demographic and economic characteristics, zip codes with greater percentage of American Indians exhibited greater incidence for all 10 substance abuse-related health outcomes (9 of 10 well supported); zip code areas within American Indian reservations had greater incidence of self-inflicted injury and drug dependence and abuse, and reduced incidence of alcohol cirrhosis and prescription opioid poisoning. However, the analyses generally demonstrated no well-supported differences in incidence associated with local residence percentages of American Indian versus African American.

CONCLUSIONS

In our analyses, ethnicity or heredity alone did not account for alcohol- and drug-related hospitalizations among Native populations. Aspects of social, economic, and political dimensions of Native lives must be considered in the etiology of alcohol- and drug-related problems for rural-dwelling indigenous peoples.

Introduction: Special issue on genetic research of alcohol use disorder in diverse racial/ethnic populations

This special issue of The American Journal on Addictions is an extension of a workshop held at the Research Society on Alcoholism (2015) highlighting several important issues related to studies of the genetic bases of alcohol use disorder among racially/ethnically diverse populations. While not exhaustive in their coverage, the papers in this special issue focus on three important topics: (1) the importance of considering the social and environmental context in genetic analyses; (2) social and cultural considerations for engaging diverse communities in genetic research; and (3) methodologies related to phenotype development for use with racially/ethnically diverse populations. A brief overview of each paper included in these three sections is presented. The issue concludes with additional considerations for genetic research with racially/ethnically diverse population groups along with a commentary. (Am J Addict 2017;26:422-423).
