Media-related cognitions are a unique influence on adolescents' substance use outcomes even after accounting for the powerful influence of parent and peers. This cross-sectional study expands upon prior research by investigating the impact of media-related cognitions on children's alcohol and tobacco outcomes in the context of parental and peer substance use. Six hundred forty-nine elementary school children (M = 9.4 years of age, SD = 1.1 years; 51 % female) completed self-report questionnaires. After accounting for peer and parental substance use, children's media-related cognitions were independently associated with three outcomes: preferences for alcohol-branded merchandise, moral beliefs about underage alcohol and tobacco use, and intentions to use alcohol and tobacco. Children's perceptions of the desirability and realism of alcohol and tobacco ads--and their similarity to and identification with these ads--predicted greater intentions to use. Desirability and identification with alcohol and tobacco ads were associated with stronger preferences for alcohol-branded merchandise, and understanding advertising's persuasive intent predicted weaker preferences. Media deconstruction skills predicted stronger beliefs that underage alcohol and tobacco use is wrong. Peer and parental substance use were associated with stronger substance-use intentions among children and weaker feelings that substance use is wrong. The findings highlight the role of media influence in contributing to youth substance use and the potential role of media literacy education in the early prevention of substance use.

Pharmacological modulation of glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) through dual GIP/GLP-1 receptor agonists, commonly used for diabetes and obesity, shows promise in reducing alcohol consumption. We applied drug-target Mendelian randomization (MR) using genetic variation at these loci to assess their long-term effects on problematic alcohol use (PAU), binge drinking, alcohol misuse classifications, liver health, and other substance use behaviors. Genetic proxies for lowered BMI, modeling the appetite-suppressing and weight-reducing effects of variants in both the GIPR and GLP1R loci ("GIPR/GLP1R"), were linked with reduced binge drinking in the primary (β = -0.

Background: Prenatal alcohol exposure (PAE) causes fetal alcohol spectrum disorder (FASD) and is associated with various cognitive and sensory impairments, including olfactory dysfunction. While both genetic and environmental factors contribute to olfactory dysfunction, PAE is considered a significant factor affecting brain development, including the olfactory system. In this study, we investigated the impact of PAE on the developing olfactory bulb (OB), specifically focusing on OB RGCs-radial glial cells that give rise to OB projection neurons.

Amidst the global shift toward cannabis legalization, this study examines medical cannabis (MC) sales as an indicator of economic activity and innovation. It explores associations between MC sales, and variables including tobacco use, alcohol consumption, amphetamine, cocaine and cannabis prevalence, and gross domestic product (GDP), using a fixed effects (FE) panel regression model. It also evaluates associations between cannabis legalization and MC sales over time using a dynamic Difference-in-Differences (DiD) approach with multiple time periods.

Objective: Modifiable health behaviors including tobacco and alcohol use, poor diet, and low physical activity increase risk for developing multiple cancers. Longitudinal research suggests that risky behaviors initiated in youth may persist into adulthood. This scoping review maps prospective longitudinal studies examining the continuity of these behaviors from youth into adulthood.

Background: Several studies have investigated the risk of complex regional pain syndrome (CRPS) and its prevention with vitamin C. However, evidence regarding the effectiveness of vitamin C for prevention of CRPS development or recurrence after total knee arthroplasty (TKA) is lacking.
Methods: This retrospective single-center observational cohort study, which utilized propensity-score matching (PSM), was conducted from January 2017 to December 2021.
