The Worsening Outcomes of the COVID-19 Lockdowns on Patients with a History of Alcoholism

Intestinal microbiome dysbiosis in alcohol-dependent patients and its effect on rat behaviors

IMPORTANCE

Intestinal microbiome dysbiosis is associated with psychiatric disease through the "microbiota-gut-brain" axis. Here, we revealed that there was obvious intestinal microbiome (including bacterial and fungal) dysbiosis in alcohol-dependent patients. Alcohol consumption seriously disturbs the gut equilibrium between bacteria and fungi, reduces the interactions among bacterial-fungal trans-kingdom, and increases intestinal permeability. Gut microbiota should be considered as a whole to study the development of alcohol dependence. The gut microbiome of alcohol-dependent patients increased the anxiety- and depression-like behavior in rats. The gut microbiota dysbiosis may promote the development of alcohol dependence by regulating the endogenous cholecystokinin (CCK) and related receptors. Hence, regulating the balance of gut microbiota and the endogenous CCK may be a potential strategy for reducing the risk of relapse in alcohol addiction patients.

"What was the vibe you were going for?" SAM Behaviors and Socialization During the COVID-19 Pandemic, a Qualitative Approach

Introduction

Marijuana use is at historic highs amongst college-aged adults, who are more likely to engage in simultaneous alcohol and marijuana use (SAM) than other age cohorts. For college students, the COVID-19 pandemic is a unique transitory phenomenon that led to isolation, as well as changes in socialization, academic environments, and substance use. This exploratory qualitative study aims to understand SAM socialization and motivation behaviors among college students.

Methods

Semi-structured qualitative interviews (N=32) were conducted across the United States from January 2021-April 2021via Zoom. Interviews were then transcribed, then a thematic analysis was conducted in Atlas.ti.

Results

The sample was primarily college juniors (mage=21). Since the pandemic, half of the participants increased SAM, whereas the other half decreased SAM. SAM was reported in different categories including primarily with friends, but, much less with partners and with roommates. More than half of the sample indicated that they used SAM alone. Motivations to engage in SAM included relaxing, socializing, offsetting stressors specific to the COVID-19 pandemic, and relieving general stress, anxiety and boredom.

Conclusion

The COVID-19 pandemic impacted college students' substance use in interesting ways. Understanding the behaviors of SAM in the context of the COVID-19 pandemic is crucial due to the legalization of marijuana in many states. This understanding has significant implications for prevention strategies and potential policy interventions. Our study yielded findings regarding the impact of socialization on SAM. We discovered that not only does socialization affect SAM, but the specific contexts and motivations behind these behaviors also play a crucial role, which adds to our developing understanding of SAM behavior.

Longitudinal factors associated with increased alcohol consumption in adults during the COVID-19 pandemic

Background: Alcohol is the most abused substance among adults in the United States. The COVID-19 pandemic impacted patterns of alcohol use, but data are conflicting, and previous studies are largely limited to cross-sectional analyses.Objective: This study aimed to longitudinally assess sociodemographic and psychological correlates of changes in three patterns of alcohol use (number of alcoholic drinks, drinking regularity, and binge drinking) during COVID-19.Methods: We studied changes in self-reported drinking behaviors in 222,195 Mayo Clinic patients over 21 years of age (58.1% female and 41.9% male) between April 1, 2019, and March 30, 2021. Logistic regression models were used to estimate associations between patient characteristics and change in alcohol consumption.Results: Sociodemographically younger age, White race, having a college degree, and living in a rural area were associated with increased alcohol use regularity (all p < .05). Younger age, male, White, high-school education or less, living in a more deprived neighborhood, smoking, and living in a rural area were associated with increases in number of alcohol drinks (all p ≤ .04) and binge drinking (all p ≤ .01). Increased anxiety scores were associated with increased number of drinks, while depression severity was associated with both increased drinking regularity and increased number of drinks (all p ≤ .02) independent of sociodemographic characteristics.Conclusion: Our study showed that both sociodemographic and psychological characteristics were associated with increased alcohol consumption patterns during the COVID-19 pandemic. Our study highlights specific target groups previously not described in the literature for alcohol interventions based on sociodemographic and psychological characteristics.

Gut Microbiome Dysbiosis in Alcoholism: Consequences for Health and Recovery

Since the mid 1980's, the impact of gastrointestinal (GI) microbiome changes during alcohol use disorder has been an area of significant interest. This work has resulted in the identification of specific changes in the abundance of certain members of the GI microbiome and the role these changes play in a variety of alcohol related disorders (i.e. alcoholic liver disease). Interestingly, some findings suggest a possible role for the GI microbiome in alcohol addiction or withdrawal. Unfortunately, there is a significant gap in knowledge in this area. Here we describe differences in the GI microbiome of alcoholic and non-alcoholic individuals and discuss the possible impact of microbes on the gut-brain axis, which could impact alcohol related behaviors (i.e. addiction). Understanding the role of the GI microbiome in alcohol related disorders will potentially lead to the development of successful microbiome-targeted therapeutics to help mitigate these disorders.
