In this global propensity score–matched cohort study, we examined the clinical and vascular consequences of comorbid alcohol abuse across diverse psychiatric disorders. Data from the TriNetX network, encompassing electronic medical records from 143 healthcare organizations, were analyzed. For each disorder—anxiety, depression, bipolar disorder, schizophrenia, reaction to severe stress, eating disorders, personality disorders, psychoactive substance dependence, developmental disorders, and obsessive-compulsive disorder—patients with alcohol abuse were matched 1:1 to those without, controlling for demographic and clinical factors. Over a 1095-day follow-up, outcomes evaluated included emergency department visits, pain prevalence, mortality, and cerebrovascular events (transient ischemic attacks and strokes). Alcohol abuse was consistently associated with significantly higher emergency care utilization, increased somatic pain, and elevated mortality across all groups. For instance, anxiety and depression cohorts exhibited 8.1% and 7.3% higher emergency visits and increased mortality by 2.7% and 2.4%, respectively, while schizophrenia showed a twofold increase in stroke risk and markedly higher pain (risk ratio 2.21). These results underscore that AUD exacerbates clinical and vascular risks in psychiatric patients, highlighting the urgent need for targeted interventions.</div></div>","PeriodicalId":7712,"journal":{"name":"Alcohol","volume":"127 ","pages":"Pages 85-92"},"PeriodicalIF":2.5,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144328082","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}

Intolerance of uncertainty (IU) – a cognitive trait linked to distress in unpredictable situations – may influence pain management and coping behaviors in these populations. This study examined whether IU moderates pain and alcohol craving responses to a pain-related stressor in individuals with CP and AUD. Fifty-five adults aged 18–65 years were enrolled, including individuals with CP only (n = 20), AUD only (n = 14), CP + AUD (n = 8), and healthy controls (n = 13). Participants completed a self-report measure of IU and the Yale Pain Stress Test (YPST), an adaptation of the Cold Pressor Test, designed to elicit pain-related stress. Behavioral pain tolerance, subjective pain and alcohol craving were assessed across two experimental sessions, one with exposure to an ice-cold water stressor and the second with a warm-water control condition. Exposure to the pain-related stressor significantly reduced behavioral pain tolerance and increased subjective pain across all groups, and also heightened alcohol craving, particularly in individuals with AUD. IU moderated the pain experience during pain-related stress: in the CP + AUD group, higher IU was associated with lower pain tolerance, whereas in the AUD group, higher IU was correlated with greater pain tolerance. IU also moderated craving responses, with higher IU predicting increased craving in individuals with both CP and AUD. These preliminary findings highlight IU as a potential treatment target, suggesting that interventions aimed at improving uncertainty tolerance may enhance pain coping and reduce stress-driven alcohol-seeking behaviors in vulnerable populations.</div></div>","PeriodicalId":7712,"journal":{"name":"Alcohol","volume":"127 ","pages":"Pages 55-61"},"PeriodicalIF":2.5,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144295485","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}

As the name implies, these circuits include the different regions of cortex and thalamus, as well as BG subregions including the striatum, globus pallidus (GP), substantia nigra (SN)/ventral tegmental area (VTA), and the subthalamic nucleus (STN). This circuitry has developed evolutionarily to provide overarching control of actions following discrete environmental events as well as self-initiated actions. Several parallel CTBG circuits have been identified and linked to different aspects of action control under different circumstances. Research in experimental psychology and Neuroscience has established how different CTBG circuits contribute to control of actions based on environmental circumstances and past learning history. There is also a large and growing body of evidence that misused substances, including alcohol, act on cells within these circuits. These actions promote acute intoxication and drug seeking and contribute to changes in behavior induced by chronic alcohol exposure, withdrawal and relapse. Alcohol exposure also influences which of the different CTBG circuits has the strongest influence on behavior. This review will cover the relevant circuitry and describe the current state of knowledge as to how alcohol alters CTBG circuit function and control of behavior. Studies in rodents, non-human primates and humans will be discussed. Finally, ideas for future research directions in this area will be considered.</div></div>","PeriodicalId":7712,"journal":{"name":"Alcohol","volume":"127 ","pages":"Pages 21-46"},"PeriodicalIF":2.5,"publicationDate":"2025-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144210462","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}

PWH often experience pain (said discomfort) and use alcohol to combat pain. We reported that short-term alcohol exposure exerts analgesic effect. Prolonged exposure is known to result in chronic pain. We hypothesize that alcohol exposure, either <em>in-vivo</em> for <em>macaques</em> or <em>in-silico</em> simulation exposure onto differentially expressed genes (DEGs) from HIV-1Tg rats and HIV patients, exacerbates discomfort in PWH. To substantiate this hypothesis, we analyzed genomic data collected from three brain datasets including the hippocampus of alcohol-exposed <em>Macaca mulatta</em> (GSE69685), HIV-1Tg rats (GSE47474), and post-mortem brain tissue of HIV-positive patients (GSE28160). Ingenuity Pathway Analysis (IPA)-Core Analysis revealed activation of neuroinflammation, neuropathic pain signaling pathways, and the inhibition of opioid signaling as well as in the increase of neuromuscular disease with neuropathy in <em>Macaca mulatta</em> exposed to binge EtOH and SIV infection. IPA-Core Analysis of the DEGs from HIV-1Tg rats, a rat model that mimics HIV patients on cART, possessing 7 of 9 HIV viral proteins, showed activation of neuroinflammation, neuropathic pain signaling pathways. IPA-Core Analysis of the DEGs from HIV patients showed activation of neuroinflammation and inhibition of neuropathic pain and increase in neuromuscular disease with neuropathy. To study the impact of alcohol exposure in HIV-1Tg rats and HIV patients, <em>in-silico</em> simulation of ethanol (EtOH) treatment mimicking exposure of alcohol onto the DEGs in response to HIV viral proteins in HIV-1Tg rats and HIV infection in HIV patients enhanced discomfort and increased neuromuscular diseases. These molecules showed significant modulation by simulated alcohol exposure, further supporting the link between alcohol use and heightened pain in PWH. Taking together, our findings suggest that alcohol consumption and HIV promote pain via modulating signaling pathways including neuroinflammation, and neuropathic pain signaling pathways and by disease like neuromuscular disease with neuropathy.</div></div>","PeriodicalId":7712,"journal":{"name":"Alcohol","volume":"126 ","pages":"Pages 43-53"},"PeriodicalIF":2.5,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144183144","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}

Evidence suggests that alcohol consumption may increase the risk for developing dementia and AD. The locus coeruleus (LC) is a region wherein the impact of alcohol and AD may converge. The LC is a noradrenergic nucleus that is highly vulnerable to degeneration in AD, and loss of LC neurons is associated with increased amyloid beta (Abeta) pathology. The present study examined whether alcohol consumption during early adulthood impacts LC degeneration and Abeta using the APP/PS1 mouse model. Female APP/PS1 mice underwent an eight-week chronic intermittent access (IA) alcohol consumption paradigm followed by twenty-three weeks of abstinence; water-consuming control subjects were run in parallel. APP/PS1 mice that had IA to alcohol showed a 21.9% decrease in the number of LC neurons and a decrease in the length of noradrenergic axons innervating the primary motor cortex. Furthermore, this alcohol induced LC deficit was associated with an increase in Abeta pathology in the primary motor cortex. In contrast to results from female APP/PS1 mice, there were no deficits in axon length and only a 9.4% decrease in the number of LC neurons in non-transgenic female subjects after abstinence from IA to alcohol. Our results demonstrate that alcohol consumption during early adulthood increases the vulnerability of LC neurons to degeneration and exacerbates Abeta pathology in female APP/PS1 mice, providing evidence that a history of alcohol abuse may impact the trajectory and severity of AD.</div></div>","PeriodicalId":7712,"journal":{"name":"Alcohol","volume":"127 ","pages":"Pages 1-9"},"PeriodicalIF":2.5,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144132153","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}

Alcohol (EtOH) is one such factor that has been shown to increase tumor size and vascularization of melanomas in xenograft mouse models and invasion of breast cancer cells in vitro. Currently, whether EtOH exposure promotes glioma progression in vivo is unknown. Here, we induced fluorescently labeled gliomas in immune-competent mice by injecting and electroporating <em>Cre</em> + CRISPR plasmids to delete tumor suppressor genes in neural progenitors lining the right lateral ventricle. Asymptomatic tumor mice were exposed to EtOH or Air vapors via inhalation chambers for five days, followed by two days of rest, then another five days of exposure. This paradigm produced blood ethanol concentrations (BECs) similar to episodic binge drinking, averaging ∼200 mg/dL on the final day of exposure. We found that EtOH exposure acutely increased tumor vascularization and invasion to the contralateral hemisphere. Notably, EtOH-exposed male mice exhibited a significant decrease in survival compared to Air-exposed controls and EtOH-exposed female mice.
