Decrease In Alcohol Consumption Research Articles

Olfactory dysfunction decreased local field potential in the reward system and increased EtOH consumption in mice

The relationship between olfactory dysfunction and alcohol intake is unobvious. Chronic alcohol intake results in reduced olfactory acuity and olfactory discrimination and addiction in humans. However, alcohol is a beverage with distinctive odors, which usually works as a cue to induce addictive memories and craving behavior. Whether olfactory impairment increase or decrease alcohol consumption remains an important but unclear issue. In this study, we measured ethanol (EtOH) consumption in the two-bottle choice EtOH drinking test, two bottle choice EtOH/sucrose drinking test and the drinking in the dark (DID) test during the olfactory loss. We also recorded local field potentials (LFPs) from the brain reward system, the ventral tegmental area (VTA), nucleus accumbens (NAc), and piriform cortex (Pir) one and four weeks after the induction of olfactory epithelium lesions using zinc sulfate (ZnSO4) in mice. The results showed that the EtOH consumption and preference were increased during the period of olfactory dysfunction. 1 week after the olfactory injury, LFP powers in the reward system at low- and high-gamma bands decreased significantly, coherence between the Pir and the reward system was also decrease. 4 weeks after the ZnSO4 treatment, LFP powers were reversed, but the coherence between VTA and NAc was decreased, indicating lasting effects post-recovery. This study demonstrates that olfactory dysfunction increased EtOH consumption in mice, which was accompanied by decreased LFP power and coherence in the reward system, which suggest that olfactory deficits changed activities in the reward system and could alter reward-seeking behaviors, which provide insights into the neurobiology of alcohol addiction.

Punitive state policies targeting alcohol use during pregnancy and alcohol consumption among pregnant women

This study aimed to determine whether punitive state alcohol policies targeting pregnant women who drink alcohol are associated with decreased alcohol consumption among pregnant women over time. This study used data from the Pregnancy Risk Assessment Monitoring System (15 states) between 1990 and 2015. A difference-in-difference (DiD) approach was employed to determine whether passage of state laws changed alcohol consumption rates among pregnant women, while controlling for state and time fixed effects. The study specifically examined punitive state alcohol policies that clarify the admissibility of evidence in child welfare proceedings related to prenatal alcohol exposure, focusing on allegations of child abuse, child neglect, child deprivation, or child dependence, as well as proceedings seeking termination of parental rights. Punitive state alcohol policies were not significantly associated with decreased rates of alcohol consumption among pregnant women (+ 1.54%, 95% CI, -1.47-4.55), within 3 years of implementation. State alcohol policies that adopted a punitive stance toward pregnant women who drink alcohol did not result in the reduction of drinking during pregnancy. Given that punitive policies may not effectively reduce alcohol consumption during pregnancy, our findings highlight the need for reevaluation and potential reform to better address maternal/child health outcomes.

The Frequency and Predictive Factors of Change in Alcohol Consumption during the COVID-19 Pandemic: Results from a Multi-Country Longitudinal Study.

The COVID-19 pandemic has had multiple health and behavioral effects in the general population worldwide, including effects on nutritional and lifestyle behavior such as alcohol consumption. This study aimed to determine the frequency of and predictors for change in alcohol consumption two years after onset of the COVID-19 pandemic among participants from the general population of six countries. Longitudinal study design with 4999 participants (47% male; aged 18-75 years) from a general population cohort from six countries: Greece, Italy, the Netherlands, Sweden, the United Kingdom (UK) and the United States of America (US). Three web-based surveys at different time waves: T1 = 22 April-1 June 2020; T2 = 2 May-29 June 2021 and T3 = 29 April-25 June 2022. The surveys included questions on self-reported retrospective alcohol consumption, demographics, health, anxiety and depression symptoms and recent life events. Of 4999 respondents, most (82.3%) reported no change in drinking habits during the pandemic, whereas 12.5% reported drinking less and 5.1% drinking more. Predictive factors for increased alcohol consumption include age 35-54 years, male gender, high educational level, moderate-severe depression symptoms, excessive drinking before the COVID-19 pandemic, no change in general health status and job loss. Predictive factors for decreased alcohol consumption were age 18-34 years, male gender, having chronic disease(s), moderate-severe depression symptoms, excessive drinking before the pandemic and job loss. The proportion of participants who reported a decrease in alcohol consumption during the COVID-19 pandemic was higher compared to those who reported an increase. Excessive drinking before the pandemic, depression symptoms and job loss were predictors for both drinking more and drinking less alcohol during the COVID-19 pandemic with an stronger association for an increase in alcohol consumption.

Expanding our understanding of long-term trends in alcohol abstention and consumption in England (2001-19) using two age-period-cohort approaches.

Alcohol consumption has decreased in England in recent decades, while alcohol-specific death rates have remained relatively stable. Age-period-cohort (APC) models offer the potential for understanding these paradoxical trends. This study aimed to use an APC model approach to measure long-term trends in alcohol abstention and consumption in England from 2001 to 2019. The study used grouped and proxy-variable APC models of repeat cross-sectional survey data, set in England (2001-19). Participants were residents in England aged 13 years or over who took part in the Health Survey for England. Outcome variables were alcohol abstention and consumption in units. We created nine age groups (13-15, 16-17, 18-24, 25-34, until 65-74 and 75+, reference 45-54 years), four periods (2001-04, 2005-09, 2010-14 to 2015-19, reference 2005-09) and 18 5-year birth cohorts (1915-19 to 2000-04, reference 1960-64). We proxied age effects (systolic and diastolic blood pressure), period effects (alcohol affordability, internet usage and household alcohol expenditure) and birth cohort effects (prevalence of smoking and prevalence of overweight). The odds of abstaining were considerably larger at young ages, 13-15 years [odds ratio (OR) = 5.38; 95% confidence interval (CI) = 4.50-6.43], were lowest during the first period, 2001-04 (OR = 0.83; 95% CI = 0.79-0.86) and had a U-shaped pattern by birth cohort. For units of alcohol, the incidence rate ratio (IRR) increased until age 18-24 years (IRR = 1.41, 95% CI = 1.34-1.48) and decreased afterwards, were highest during the first period, 2001-04 (IRR = 1.07; 95% CI = 1.05-1.08) and showed an inverted J-shape by birth cohort. Our proxy variable approach revealed that using blood pressure measures, alcohol affordability and prevalence of overweight as proxies resulted in APC effects that differed from our base-case model. However, internet usage, household expenditure on alcohol and smoking prevalence resulted in APC effects similar to our base-case model. The discrepancy between decreasing alcohol consumption and increasing alcohol-related deaths observed in England from 2001 to 2019 may, in part, be explained by the halt in abstention trends since 2010 and a slight consumption decline since 2001.

Associations of role, area deprivation index, and race with health behaviors and body mass index among localized prostate cancer patients and their partners.

To examine the associations of role (localized prostate cancer (PCa) patient vs. their intimate partner), area deprivation index (ADI-higher scores indicating higher neighborhood deprivation levels), and race (Black/African American (AA) vs. White) with health behaviors and body mass index (BMI) among PCa patients and partners. The behaviors include smoking, alcohol consumption, diet quality, sedentary behaviors, and physical activity (PA). This study used the baseline data collected in a clinical trial. Given the nested structure of the dyadic data, multi-level models were used. Significant role-race interaction effects on smoking, ADI-race effects on alcohol consumption, and role-ADI effects on BMI were found. Meanwhile, patients smoked more cigarettes, decreased alcohol consumption, had less healthful diets, spent longer time watching TV, did fewer sedentary hobbies, had more confidence in PA, and had higher BMIs than their partners. High ADI was independently associated with lower odds of drinking alcohol, using computer/Internet, and doing non-walking PA, and higher BMI compared to low ADI controlling for role and race. Black/AA dyads had less smoking amount and alcohol consumption and higher sedentary time and BMI than White dyads when adjusted for role and ADI. This study identified significant interaction and main effects of role, ADI, or race on health behaviors and BMI. Future behavioral interventions should address divergent individual needs between patients and partners, social and neighborhood barriers, and cultural indicators of racial groups to promote healthful behaviors and improve the quality of survivorship for PCa patients and partners.

Escalating caffeine dose-dependently increases alcohol consumption in adult male, but not female, C57BL/6J mice

Although previous research has illustrated the effects of the consumption of alcohol and caffeine individually, less research has focused on the popular combination of the two drugs. The increase in alcohol consumption when combined with caffeine has led to the idea that the stimulant effects of caffeine may mask the depressant effects of alcohol, and this may contribute to increased binge drinking as the individual feels more awake and stimulated. Preclinical research has shown various effects of combined alcohol and caffeine where several studies show decreased alcohol consumption and others show increased alcohol consumption and even binge-like drinking. Results from a previous study in our lab indicate that intermittent access (IA) to steady levels of low (0.015 %) but not moderate (0.03 %) caffeine increased alcohol consumption in male C57BL/6J mice. The current studies further investigated the sex and dose differences in adult mice receiving varying concentrations of caffeine on combined alcohol intake. In Experiment 1, adult mice (n = 50, 25 males and 25 females) had IA to one of the following experimental bottles throughout the 4 week period: water, alcohol (10 % v/v), caffeine (0.015 % w/v), or 10 % alcohol +0.015 % caffeine. In Experiment 2, adult mice (n = 70, 35 males and 35 females) were given IA to one of the following experimental bottles: water, alcohol (10 % v/v; steady, maintained throughout the 4 weeks), caffeine (increasing 0.01 % to 0.015 % to 0.02 % to 0.03 % weekly), or 10 % alcohol+increasing caffeine (at the previously mentioned concentrations). When both caffeine and alcohol concentrations remained steady throughout the 4 weeks, there was no change in alcohol consumption. Chronic exposure to IA caffeine led to increased locomotor activity and decreased freezing episodes when tested in the open field test approximately 6 h after removal of the bottles. In Experiment 2, caffeine dose-dependently increased alcohol co-consumption in male mice whereas female mice consumed less alcohol when it was presented in conjunction with caffeine. The results in males are in line with clinical literature suggesting that the combination of alcohol and caffeine may lead to increased stimulation and alcohol drinking. Additionally, these studies provide evidence that the escalation of caffeine is crucial when investigating alcohol and caffeine co-consumption using the IA paradigm.

Effects of social housing on alcohol intake in mice depend on the non-social environment.

Excessive alcohol consumption leads to serious health problems. Mechanisms regulating the consumption of alcohol are insufficiently understood. Previous preclinical studies suggested that non-social environmental and social environmental complexities can regulate alcohol consumption in opposite directions. However, previous studies did not include all conditions and/or did not include female rodents. Therefore, in this study, we examined the effects of social versus single housing in standard versus non-standard housing conditions in male and female mice. Adult C57BL/6 J mice were housed in either standard shoebox cages or in automated Herdsman 2 (HM2) cages and exposed to a two-bottle choice procedure with 3% or 6% ethanol versus water for 5 days. The HM2 cages use radiotracking devices to measure the fluid consumption of individual mice in an undisturbed and automated manner. In both housing conditions, mice were housed either at one or at four per cage. In standard cages, group housing of animals decreased alcohol consumption and water consumption. In HM2 cages, group housing significantly increased ethanol preference and decreased water intake. There were no significant differences in these effects between male and female animals. These observations were similar for 3 and 6% ethanol solutions but were more pronounced for the latter. The effects of social environment on ethanol preference in HM2 cages were accompanied by an increase in the number of approaches to the ethanol solution and a decrease in the number of approaches to water. The differences in ethanol intake could not be explained by differences in locomotor or exploratory activity as socially housed mice showed fewer non-consummatory visits to the ethanol solutions than single-housed animals. In addition, we observed that significant changes in behaviors measuring the approach to the fluid were not always accompanied by significant changes in fluid consumption, and vice versa, suggesting that it is important to assess both measures of motivation to consume alcohol. Our results indicate that the direction of the effects of social environment on alcohol intake in mice depends on the non-social housing environment. Understanding mechanisms by which social and non-social housing conditions modulate alcohol intake could suggest approaches to counteract environmental factors enhancing hazardous alcohol consumption.

The entactogen 3,4-methylenedioxymethamphetamine (MDMA; ecstasy) as a treatment aid in psychotherapy and its safety concerns.

The phenylethylamine, 3,4-methylenedioxymethamphetamine (MDMA, 'ecstasy'), is the prototypical example of an entactogen. Its original placement in highly restrictive drug usage categories in the US and UK, led to an inevitable restriction on MDMA neuroscience research and treatment. The dominant pharmacological effects of MDMA are its properties of release and inhibition of reuptake of amine neurotransmitter transporters for dopamine, norepinephrine, and serotonin. MDMA is an agonist of a wide range of receptors; its mood-altering effects are mediated via 5-HT2A receptors; this receptor may also mediate its effects on body temperature, analgesia, and anxiolytic properties. The mechanisms underlying MDMA's entactogenic properties of sociability and interpersonal closeness are not known but release and involvement of oxytocin, a peptide thought by some to be involved in social bonding, has been suggested. Adverse effects of MDMA are mostly transient; acute multiorgan adverse effects occurring during raves or crowded dance gatherings include dehydration, hyperthermia, seizures, rhabdomyolysis, disseminated intravascular coagulation, and acute renal failure. Deaths following MDMA taken by itself are rare compared to fatalities following coadministration with other drugs. A recent FDA-approved phase 3 clinical trial of MDMA for post-traumatic stress disorder (PTSD) led to the conclusion that MDMA-assisted therapy represents a potential breakthrough treatment meriting expedited clinical evaluation. Despite the ongoing deliberations by the FDA and EMA for approval of MDMA treatment of PTSD, the Australian Therapeutic Goods Administration (TGA) recently announced that after an evaluation of the therapeutic value, benefits, and risks of MDMA, it will permit its prescribing for the treatment of PTSD. Further examples of regulatory relaxation toward MDMA-assisted psychotherapy are underway. These include the FDA's recently approved clinical trial to assess MDMA's efficacy in the treatment of "asociality" in patients with schizophrenia and an open trial of MDMA treatment for alcohol-use disorder which showed decreased alcohol consumption. There are also ongoing studies on the little understood startle response, anxiety associated with life-threatening illness, and social anxiety in autistic adults.

Is Phenobarbital an Effective Treatment for Alcohol Withdrawal Syndrome?

BackgroundAlcohol use disorder is associated with a variety of complications, including alcohol withdrawal syndrome (AWS), which may occur in those who decrease or stop alcohol consumption suddenly. AWS is associated with a range of signs and symptoms, which are most commonly treated with GABAergic medications. Clinical QuestionIs phenobarbital an effective treatment for AWS? Evidence ReviewStudies retrieved included two prospective, randomized, double-blind studies and three systematic reviews. These studies provided estimates of the effectiveness and safety of phenobarbital for treatment of AWS. ConclusionsBased on the available literature, phenobarbital is reasonable to consider for treatment of AWS. Clinicians must consider the individual patient, clinical situation, and comorbidities when selecting a medication for treatment of AWS.

Sodium Bicarbonate Decreases Alcohol Consumption in Mice.

We previously reported that mice with low neuronal pH drink more alcohol, demonstrating the importance of pH for alcohol reward and motivation. In this study, we tested whether systemic pH affects alcohol consumption and if so, whether it occurs by changing the alcohol reward. C57BL/6J mice were given NaHCO3 to raise their blood pH, and the animals' alcohol consumption was measured in the drinking-in-the-dark and two-bottle free choice paradigms. Alcohol consumption was also assessed after suppressing the bitterness of NaHCO3 with sucrose. Alcohol reward was evaluated using a conditioned place preference. In addition, taste sensitivity was assessed by determining quinine and sucrose preference. The results revealed that a pH increase by NaHCO3 caused mice to decrease their alcohol consumption. The decrease in high alcohol contents (20%) was significant and observed at different ages, as well as in both males and females. Alcohol consumption was also decreased after suppressing NaHCO3 bitterness. Oral gavage of NaHCO3 did not alter quinine and sucrose preference. In the conditioned place preference, NaHCO3-treated mice spent less time in the alcohol-injected chamber. Conclusively, the results show that raising systemic pH with NaHCO3 decreases alcohol consumption, as it decreases the alcohol reward value.

Sodium Bicarbonate Decreases Alcohol Consumption in Mice

pH is an important biological factor in the brain as H+ alters the structure and function of many ion channels, transporters and receptors, thus affecting relevant synaptic activities and complex firing patterns. pH may change activities in the neural circuits responsible for motivation and reward, such that drug reward values or modulatory properties are modified to change drinking frequency and amount. In this study, we tested whether alcohol consumption can be affected by systemic pH in mice. C57BL/6J mice were given free access to 0.2 M NaHCO3 for 6 days, which resulted in a 0.2 pH unit increase compared to water-fed control mice ( p < 0.05; n = 6/group). Mice were then subjected to voluntary alcohol consumption in the two-bottle free choice procedure with one bottle containing water and the other containing 5-20% alcohol (5% increment for 4 days each). NaHCO3-fed mice consumed similar amounts of 5-15% alcohol as pair-fed mice but decreased the consumption of 20% alcohol (p < 0.05). Consistent with this result, NaHCO3-fed mice had decreased alcohol preference (i.e., alcohol intake/total fluid intake) at 20%. These changes were observed in both males and females. In separate experiments, mice were subjected to the two-bottle free choice procedure using water and 20% alcohol, with both bottles containing 0.05-0.4 M NaHCO3. The alcohol consumption was significantly decreased in the presence of 0.1 M or higher NaHCO3. The minimum effective dose of NaHCO3 was 0.08 g/kg body weight, calculated from the amount of alcohol mice consumed. Determined by the diarrhea scoring system, mice produced a normal state of feces after receiving 0.4 M NaHCO3 for 2 days, thus indicating negligible abdominal discomfort at this concentration. In other experiments, mice were given NaHCO3 by oral gavage and 1 hour later subjected to 20% alcohol in the drinking in the dark procedure. The alcohol consumption was significantly decreased in NaHCO3-fed mice, compared to pair-fed mice. In conclusion, our study shows that mildly raising blood pH by NaHCO3 decreases alcohol consumption in mice. Given that pH change has been considered as a consequence of alcohol metabolism, our data provide first evidence on the pH as a factor affecting alcohol consumption.

Randomized Controlled Trial on Imaginal Retraining for Problematic Alcohol Use: A Dismantling Study.

Imaginal retraining (IR) is an approach-avoidance procedure that has shown promising results in previous studies. The aim of the present study was to dismantle the efficacy of IR's components in a randomized controlled trial (RCT). We conducted a RCT with nine conditions comprising eight intervention groups and a waitlist control group (WLC). Alcohol craving (primary outcome), consumption, depressive symptoms, quality of life, subjective appraisal, and side effects were assessed online at baseline, post intervention (6 weeks), and follow-up (12 weeks). The sample consisted of 426 participants (age: M = 47.22, SD = 11.82, women: 50.5%). The intervention groups received instructions for four different components of IR (mood induction, mental avoidance of unhealthy stimuli, motor avoidance of unhealthy stimuli, approach to healthy stimuli) that were each conveyed with or without prior psychoeducation (PE). The intervention was delivered online. At total of 163 individuals (42.9%) used the intervention at least once. No group differences were found for any primary or secondary outcome after Šidák correction. Uncorrected statistics showed effects of significantly decreased alcohol consumption for the approach + PE group in the intention-to-treat and the merged motor avoidance group in the per-protocol analyses at post assessment compared with the WLC. Exploratory moderation analyses revealed that individuals with high visualization skills benefited most. The authors conclude that visualization training and motivational components may increase the efficacy and adherence of IR.

Mining clinical data for novel medications to treat alcohol use disorder

BackgroundAlcohol use disorder (AUD) is a highly prevalent and often debilitating condition associated with high morbidity and mortality. Current AUD medications have limited efficacy and uptake. Alternative pharmacological options are needed. MethodsWe constructed a mechanistic tree of all US Food and Drug Administration approved medications and used a tree-based scan statistic, TreeScan, to identify medications associated with greater than expected improvements in alcohol consumption. Our cohort included all United States (US) Department of Veterans Affairs (VA) patients with a diagnosis of AUD between 10/1/1999 and 9/30/2019 with multiple Alcohol Use Disorders Identification Test-Consumption Module scores within the VA electronic health record data. ResultsMedications statistically associated with decreased alcohol consumption had, at large, minor effect sizes. Medications used in the treatment of chronic or life-threatening conditions like diabetes, chronic kidney disease, hepatitis C virus, or cancer produced larger effect sizes. Asenapine, an atypical antipsychotic, had a large effect with an observed to expected ratio of 1.78 (p = 0.003). Our findings were replicated in a propensity score matched population. ConclusionMost medications significantly associated with decreased alcohol consumption in our analysis were either contraindicated with alcohol or likely attributable to patients abstaining from alcohol due to severe illness. However, the large effect of asenapine is notable, and a worthwhile candidate for more careful analysis.

Physical activity and sedentary behavior among school-going adolescents in low- and middle-income countries: insights from the global school-based health survey.

The Global School Student Health Survey (GSHS) is being carried out by students in various countries across the globe to advance improved health programs for youth. However, in comparison to high-income countries, adolescents in low- and middle-income countries (LMICs) are generally at an early stage of understanding regarding physical activity (PA) and sedentary behavior (SB), often exhibiting low levels of PA and high levels of SB. Furthermore, there is limited evidence connecting PA and SB in school-going adolescents from LMICs. The objective of this review was to synthesize the available evidence regarding PA and sedentary behavior among school-going adolescents in LMICs using data from the GSHS. On March 18, 2023, a systematic literature search was performed across four electronic databases, namely Web of Science, PubMed, ScienceDirect, and EBSCO with n odaterestrictions. Studies were eligible if they: (1) utilization of data sourced from the Global Student-based Health Survey; (2) exploration of physical activity; (3) specific focus on adolescents; (4) conducted in low- and middle-income countries; (5) study design encompassing observational; (6) published as English journal articles. Among the 29 studies included in the analysis, the majority revealed elevated levels of sedentary behavior and diminished levels of PA in low- and middle-income countries. Furthermore, notable disparities in physical engagement and sedentary behavior were noted between male and female adolescents (p < 0.001). Augmented PA among teenagers was observed to correlate with higher consumption of vegetables and fruits (AOR = 1.30; 95% CI [1.13-1.50]; p < 0.001), decreased alcohol consumption, and a reduced prevalence of loneliness and depression (aOR 1.37, 95% CI [1.18-1.59]). The results of this review affirm that in contrast to high-income countries, adolescents in low- and middle-income countries (LMICs) are in the early stages of comprehending physical activity, marked by low levels of PA. Physical activity and sedentary behavior in school-going adolescents from LMICs appear to be influenced by factors such as policies, cultural norms, socioeconomic conditions, as well as gender, and age.

The decrease in alcohol consumption and suicide rate during the COVID-19 pandemic and their association

Despite the considerable change in alcohol consumption during the COVID-19 pandemic, the impact of the pandemic on the suicide rate in terms of alcohol consumption was not studied. This study was performed to examine whether the change in the suicide rate during the COVID-19 pandemic was related to alcohol consumption and whether the relation was specific to suicides when compared to mortality due to other causes. We performed a comparative interrupted time series (CITS) analysis for the suicide rate of people aged 19 to 60 with three comparison groups (the suicide rate of people aged 19 and under, the cancer death rate of people aged 19 to 60, and alcohol-induced death rates). The suicide rate of people aged 19 to 60 and alcohol consumption per capita, along with alcohol-induced death rates, continued to decrease during the pandemic in 2020 and 2021, while the suicide rate of people aged 19 and under and the cancer death rate showed increases. In the comparative interrupted time series model, alcohol consumption had an increasing effect on the adult suicide rate compared to comparison groups when time trends and changes associated with COVID-19 were adjusted. This study shows that the decrease in the adult suicide rate in Korea during the pandemic was associated with the decrease in alcohol use among the adult population. Considering that means restriction is the most effective way of controlling suicide and that alcohol can be the most potent and final trigger for suicide, the decrease in suicides during the pandemic and its association with alcohol consumption should be understood as a call for further efforts to decrease alcohol consumption.

Upward Mobility Context and Health Outcomes and Behaviors during Transition to Adulthood: The Intersectionality of Race and Sex.

This study investigates how upward mobility context affects health during transition to adulthood and its variations by race and sex. Using county-level upward mobility measures and data from the Panel Study of Income Dynamics, we apply propensity score weighting techniques to examine these relationships. Results show that low upward mobility context increases the likelihood of poor self-rated health, obesity, and cigarette use but decreases alcohol consumption probability. Conversely, high upward mobility context raises the likelihood of distress, chronic conditions, and alcohol use but reduces cigarette use likelihood. In low-opportunity settings, Black individuals have lower risks of chronic conditions and cigarette use than White men. In high-opportunity settings, Black women are more likely to experience depression and chronic conditions, and Black men are likelier to smoke than White men. Our findings emphasize the complex link between upward mobility context and health for different racial and sex groups.

Liraglutide Reduces Alcohol Consumption, Anxiety, Memory Impairment, and Synapse Loss in Alcohol Dependent Mice.

Glucagon-like peptide 1 (GLP-1) analogues have been commercialized for the management of type 2 diabetes. Recent studies have underscored GLP-1's role as a modulator of alcohol-related behavior. However, the role of the GLP-1 analogue liraglutide on alcohol-withdrawal responses have not been fully elucidated. Liraglutide binds to the G-protein-coupled receptor and activates an adenylyl cyclase and the associated classic growth factor signaling pathway, which acts growth factor-like and neuroprotective properties. The underlying neurobiological mechanisms of liraglutide on alcohol withdrawal remains unknown. This study endeavored to explore the effects of liraglutide on the emotion and memory ability of alcohol-withdrawal mice, and synaptic morphology in the medial prefrontal cortex (mPFC) and the hippocampus (HP), and thus affects the relapse-like drinking of alcohol-withdrawal mice. The alcohol-withdrawal group was reintroduced to a 20% v/v alcohol and water through the two-bottle choice for four consecutive days, a period referred to as alcohol re-drinking. Male C57BL/6J mice were exposed to a regimen of 20% alcohol and water for a duration of 6 weeks. This regimen established the two-bottle choice model of alcohol exposure. Learning capabilities, memory proficiency, and anxiety-like behavior were evaluated using the Morris water maze, open field, and elevated plus maze paradigms. Furthermore, synaptic morphology and the levels of synaptic transport-related proteins were assessed via Golgi staining and Western Blot analysis after a two-week alcohol deprivation period. Alcohol re-drinking of alcohol-withdrawal mice was also evaluated using a two-bottle choice paradigm. Our findings indicate that liraglutide can substantially decrease alcohol consumption and preference (p < 0.05) in the alcohol group and enhance learning and memory performance (p < 0.01), as well as alleviate anxiety-like behavior (p < 0.01) of alcohol-withdrawal mice. Alcohol consumption led to a reduction in dendritic spine density in the mPFC and HP, which was restored to normal levels by liraglutide (p < 0.001). Furthermore, liraglutide was found to augment the levels of synaptic transport-related proteins in mice subjected to alcohol withdrawal (p < 0.01). The study findings corroborate that liraglutide has the potential to mitigate alcohol consumption and ameliorate the memory impairments and anxiety induced by alcohol withdrawal. The therapeutic efficacy of liraglutide might be attributed to its role in counteracting synapse loss in the mPFC and HP regions and thus prevented relapse-like drinking in alcohol-withdrawal mice.

Impact on wine sales of removing the largest serving size by the glass: An A-B-A reversal trial in 21 pubs, bars, and restaurants in England.

Interventions that alter aspects of the physical environments in which unhealthy behaviours occur have the potential to change behaviour at scale, i.e., across populations, and thereby decrease the risk of several diseases. One set of such interventions involves reducing serving sizes, which could reduce alcohol consumption. The effect of modifying the available range of serving sizes of wine in a real-world setting is unknown. We aimed to assess the impact on the volume of wine sold of removing the largest serving size by the glass from the options available in licensed premises. The study was conducted between September 2021 and May 2022 in 21 licensed premises in England that sold wine by the glass in serving sizes greater than 125 ml (i.e., 175 ml or 250 ml) and used an electronic point of sale till system. It used an A-B-A reversal design, set over 3 four-weekly periods. "A" represented the nonintervention periods during which standard serving sizes were served and "B" the intervention period when the largest serving size for a glass of wine was removed from the existing range in each establishment: 250 ml (18 premises) or 175 ml (3 premises). The primary outcome was the daily volume of wine sold, extracted from sales data. Twenty-one premises completed the study, 20 of which did so per protocol and were included in the primary analysis. After adjusting for prespecified covariates, the intervention resulted in -420·8 millilitres (ml) (95% confidence intervals (CIs) -681·4 to -160·2 p = 0·002) or -7·6% (95% CI -12·3%, -2·9%) less wine being sold per day. There was no evidence that sales of beer and cider or total daily revenues changed but the study was not powered to detect differences in these outcomes. The main study limitation is that we were unable to assess the sales of other alcoholic drinks apart from wine, beer, and cider, estimated to comprise approximately 30% of alcoholic drinks sold in participating premises. Removing the largest serving size of wine by the glass from those available reduced the volume of wine sold. This promising intervention for decreasing alcohol consumption across populations merits consideration as part of alcohol licensing regulations.

Decisional balance, beliefs, and knowledge of nursing care toward alcohol: nursing intervention

Introduction: the progressive increase of alcohol consumption justifies the demand of users in primary care, clinical and surgical units; resulting in the prevention of the use of this substance a priority for nursing professionals in relation to their functions and main objective to provide quality interventions to the individual, family, or community. Objective: to modulate the decisional balance, beliefs, and knowledge of nursing care towards alcohol through a nursing intervention. Methodology: psychoeducational intervention, quasi-experimental, of mixed type, explanatory character, by the qualitative is ethnographic, of longitudinal cohort, prospective, since it was carried out in time series with measurement before and after the intervention applying pre and posttest evaluation instruments during the time, in order to evaluate the effectiveness of a nursing intervention.
