Glucagon-like peptide-1 (GLP-1) is involved in a range of central and peripheral pathways related to appetitive behavior. Hence, this study explored the effects glucagon-like receptor agonists (GLP-1 RAs) on substance behavioral addictions, including alcohol, caffeine, nicotine, cannabis, psychostimulants, compulsive shopping, sex drive/libido. Data were collected from various social platforms. Keywords GLP-1 RAs substance/behavioral addiction used extract relevant comments. The employed mixed-methods approach analyze online discussions posted December 2019 June 2023 using specialized web application. Reddit entries focus here due limited data other platforms, such as TikTok YouTube. A total 5859 threads comments extracted six subreddits, which included about drugs associated brand names. To obtain posts, keywords potential use behavior selected. Further analysis two main steps: (1) manually coding posts based users’ references impact non-substance habits, excluding irrelevant or unclear comments; (2) performing thematic dataset keywords, AI-assisted techniques followed by manual revision generated themes.

The Gut Microbiome-Liver-Brain Axis is a relatively novel construct with promising potential to enhance our understanding of Alcohol Use Disorder (AUD), and its therapeutic approaches. Significant alterations in the gut microbiome occur AUD even before any other systemic signs or symptoms manifest. Prolonged inappropriate alcohol consumption, by affecting microbiota mucosa permeability, thought contribute development behavioral cognitive impairments, leading Alcohol-Related Liver Disorders potentially progressing into alcoholic cirrhosis, which often associated severe impairment related neurodegeneration, such as hepatic encephalopathy dementia. critical role further supported efficacy FDA-approved treatments for cirrhosis (i.e., lactulose rifaximin).

The healthy gut microbiome is important in maintaining health and preventing various chronic metabolic diseases through interactions with the host via different gut–organ axes, such as gut-brain, gut-liver, gut-immune, gut-lung axes. human relatively stable, yet can be influenced by numerous factors, diet, infections, diseases, medications which may disrupt its composition function. Therefore, microbial resilience suggested one of key characteristics a humans. However, our understanding definition indicators remains unclear due to insufficient experimental data. Here, we review impact drivers including intrinsic extrinsic factors diet antibiotics on microbiome. Additionally, discuss concept resilient highlight potential biomarkers diversity indices some bacterial taxa recovery-associated bacteria, resistance genes, antimicrobial peptides, functional flexibility. These facilitate identification prediction microbiomes, particularly precision medicine, diagnostic tools or machine learning approaches especially after that cause stable dysbiosis.

Reciprocal communication between the gut microbiota and brain, commonly referred to as “gut-brain-axis” is crucial in maintaining overall physiological homeostasis. Gut development brain maturation (neuronal connectivity plasticity) appear be synchronized follow same timeline during childhood (immature), adolescence (expansion) adulthood (completion). It important note that mesolimbic reward circuitry develops early on, whereas of inhibitory frontal cortical neurons delayed. This imbalance can lead increased acquirement reward-seeking risk-taking behaviors adolescence, consequently eventuate heightened risk for substance abuse. Thus, there high initiation alcohol drinking significantly increases use disorder (AUD) adulthood. The underlying causes AUD are not well understood. suggested alcohol-associated impairment plays a key role neurodevelopment Furthermore, alcohol-induced dysregulation microglia, either directly or indirectly through interaction with microbiota, may critical neuroinflammatory pathway leading neurodevelopmental impairments AUD.

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