Co-use of alcohol and cannabis is of particular concern since individuals who co-use alcohol and cannabis use more of each substance and experience greater substance-related harm. Pain and substance use frequently co-occur, and a growing body of literature indicates pain is unique risk factor for substance use. The goal of the current study was to examine moderate/severe pain (vs. no/low pain) as a prospective predictor of engaging in co-use of alcohol and cannabis among emerging adults, and to test sex as a moderator of this hypothesized relationship. Data were drawn from Waves 1–5 of the Population Assessment of Tobacco and Health Study (<em>n</em> = 3544). Unadjusted logistic regression revealed that those with moderate/severe pain at baseline were 1.4 times more likely to engage in past-month co-use of alcohol and cannabis over the next four years (<em>p</em> = .046). The effects of pain on co-use were no longer significant after inclusion of covariates and a pain∗sex interaction term, which was also nonsignificant (<em>ps</em> &gt; .05). These findings provide initial support for pain as a risk factor for engaging in co-use of alcohol and cannabis during emerging adulthood. Future research should continue investigating how pain may motivate co-use of alcohol and cannabis, exploring how pain is associated with other measures of co-use, and determining how providers can incorporate pain-substance use psychoeducation for emerging adults in clinical settings.</div></div>","PeriodicalId":7712,"journal":{"name":"Alcohol","volume":"124 ","pages":"Pages 111-119"},"PeriodicalIF":2.5,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143525493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite their advantages in cost effectiveness, modularity, and customization, measurements obtained using newly developed devices may not always recapitulate measurements from existing and validated equipment, potentially due to the materials used in manufacture. In this study, we evaluated a commonly used open-source optical lickometer that delivers fluid via a Hydropac® plastic valve in a multi-site intermittent access two-bottle choice (IA2BC) paradigm for alcohol consumption. Mice were tested with both traditional metal sippers and plastic sippers equipped with Hydropac® valves to assess differences in alcohol intake, preference, and total fluid consumption. Our findings revealed that mice displayed reduced intake and preference for alcohol (10–20% v/v) delivered via the Hydropac® containing plastic sippers. Notably, the effect was observed at both testing sites, suggesting a generalizable phenomenon. The decreased intake was also specific to alcohol, as water, quinine, and sucrose consumption were unaffected by sipper type. To investigate the underlying cause of the reduced alcohol consumption, we pre-incubated Hydropac® valves in 20% alcohol and found that the pre-treated alcohol reduced intake even when delivered via metal sippers. This suggests that prolonged interaction between alcohol and the components of the Hydropac® valves alter the fluid, likely by generating unpalatable contaminants. These results highlight a limitation of using plastic sippers in long-term alcohol self-administration studies. While these devices may remain suitable for limited access paradigms their use in extended access protocols may compromise data integrity.

Tissue plasminogen activator (tPA), a serine protease with pleiotropic effects in the brain, plays a critical role in modulating neuroplasticity and stress responses. This study investigates the behavioral and molecular effects of tPA gain-of-function in a social stress paradigm in male C57BL/6 mice using lentiviral vectors. Behaviorally, hippocampal tPA gain-of-function mitigated depression-like responses in the novelty-suppressed feeding, sucrose splash, tail suspension, and forced swim tests following exposure to chronic social stress. Additionally, in a two-bottle choice drinking paradigm, tPA overexpression reduced social stress-induced ethanol intake and preference, suggesting a role in dampening maladaptive coping behaviors. However, analysis of tastants’ intake and preference revealed no significant effects of tPA overexpression, indicating that it does not influence hedonic responses under stress conditions. Molecularly, tPA overexpression preserved hippocampal tPA mRNA expression and maintained levels of mature brain-derived neurotrophic factor in the hippocampus despite chronic stress exposure. These findings highlight the potential neuroprotective effects of tPA in maintaining hippocampal plasticity and mitigating stress-induced dysregulation of critical neurotrophic pathways.

Both stress and chronic ethanol can enhance neuroinflammatory processes, which may dysregulate limbic circuits involved in ethanol reinforcement. Clinical and preclinical studies have identified sex differences in alcohol intake in response to neuroinflammatory triggers. Since both cyclic AMP (cAMP) signaling and microglial activation contribute to neuroinflammation, we explored their contribution to stress-induced ethanol drinking in mice. To this end, we first trained C57BL/6J male and female mice to volitionally drink ethanol through a modified version of the “Drinking-in-the-Dark” paradigm. We then assessed whether exposure to foot shock stress followed by repeated exposure to the previously stress-paired context might alter volitional ethanol drinking. We observed that stress exposure resulted in a delayed increase in ethanol intake, but only in female mice. The anti-inflammatory drug Apremilast, an inhibitor of phosphodiesterase type 4 (PDE4; the primary enzyme for cAMP degradation in the brain), reduced ethanol intake and decreased preference for ethanol regardless of stress exposure in females. In contrast, a partial pharmacological depletion of microglia via PLX3397 treatment did not significantly alter baseline ethanol drinking or stress-induced ethanol drinking in female mice. This study shows that female mice are more susceptible to stress-induced ethanol drinking than males, and that this occurs even after partial microglial depletion. In addition, modulation of cAMP signaling by Apremilast administration reduced ethanol drinking regardless of stress exposure, supporting the idea that it might be useful for treatment of AUD.</div></div>","PeriodicalId":7712,"journal":{"name":"Alcohol","volume":"122 ","pages":"Pages 31-42"},"PeriodicalIF":2.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142900636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Male and female Sprague–Dawley rats were assessed for baseline anxiety-like behavior using acoustic startle and the elevated plus maze (EPM).

Hence, we designed a methodological approach to investigate the pathophysiological mechanisms and pharmacological outcomes of morin, a neuroprotective flavonoid in mice. After 7 days of PTSD following single-prolonged stress (SPS) induction in mice, the PTSD mice were exposed to intermittent binge ethanol administration using ethanol (2 g/kg, oral gavage) every other day, alongside daily morin (50 and 100 mg/kg) or fluoxetine (10 mg/kg) from days 8–21.

The exacerbated anxiety-like behavior, and spatial/non-spatial memory deficits, with general depressive phenotypes and social stress susceptibility by SPS-ethanol interaction, were alleviated by morin and fluoxetine, evidenced by reduced corticosterone release and adrenal hypertrophy. SPS-ethanol exacerbates dopamine, serotonin, and glutamic acid decarboxylase alterations, and monoamine oxidase-B and acetylcholinesterase hyperactivities in the striatum, PFC, and hippocampus, respectively, which were prevented by morin. Compared to SPS-ethanol aggravation, morin reduced TNF-α and IL-6 release, malondialdehyde and nitrite levels, with improved antioxidant (glutathione, superoxide-dismutase, catalase) levels in the hippocampus, PFC, and striatum.
