The $2.7 million grant from the National Institutes of Health will enable researchers to identify interventions that will lead to a healthier, more resilient Native American community.
Researchers show that high estrogen levels may make alcohol more rewarding to female mice and reducing the number of estrogen receptors led to decreased drinking behavior, but only in female mice.
Female college students appear to be more affected by high alcohol use than men, which may lead to less interest in academics, according to new research including by faculty at Binghamton University, State University of New York.
The brain responds to rewarding stimuli by increasing the release of a neurotransmitter called dopamine. When we feel motivated, it is because our brain anticipates this dopamine reward.
The transition from early to mid-adolescence is associated with increased reward sensitivity and reward-seeking behavior, a consequence of normal brain development. This heightened sensitivity or prioritization of reward can be thought of as reflecting a greater motivation to obtain rewards. A new study, published in Alcoholism: Clinical and Experimental Research, has addressed whether drinking alcohol in early adolescence might impact the brain’s reward systems, by examining associations between alcohol initiation and subsequent changes in reward motivation while accounting for baseline scores. Differences between boys and girls were also evaluated.
Early exposure to anesthetics may make adolescents more susceptible to developing alcohol use disorder (AUD), according to new research from Binghamton University, State University of New York.
A University of Louisville study will evaluate how health care, public health and social services organizations are working together to improve the health and well-being of individuals served through Freedom House programs in Louisville and Manchester, Ky.Freedom House, operated by Volunteers of America Mid-States (VOAMID), is a residential treatment program for alcohol and/or drug dependent pregnant women and women with young children.
Researchers and clinicians can better understand the health risks facing people with HIV through comprehensive measures of alcohol use, including objective biomarkers, according to a new study in Alcoholism: Clinical and Experimental Research. Frequent or heavy alcohol use in people with HIV can affect HIV disease progression and comorbidities. Alcohol use disorder is a barrier to effectively managing HIV and contributes in multiple ways to poor health outcomes. These effects are not well understood, however, owing in part to the limitations of self-report tools (questionnaires) for measuring alcohol use. Researchers at Louisiana State University and Tulane University correlated self-reported alcohol use, measured by multiple questionnaires, with a biomarker of alcohol consumption in people with HIV. This study explores the implications of this multi-faceted approach for understanding the alcohol use of people with HIV and the related risk factors.
A simple screening test could help identify infants at risk of fetal alcohol spectrum disorders (FASD), according to a report in the journal Alcoholism: Clinical and Experimental Research. Prenatal exposure to alcohol can cause a wide range of lifelong physical, behavioral, and cognitive disabilities, encompassed by the umbrella term FASD. Identifying babies at risk for FASD has previously relied on maternal self-reports of drinking in pregnancy; however, this can be unreliable, as women may under-report their drinking because of recall bias or fear of stigma. Recently, biological markers have been identified that can provide more objective data on prenatal alcohol exposure and supplement information from maternal self-reports. One such biomarker, phosphatidylethanol (PEth), is a direct marker of alcohol metabolism that can indicate exposure with a high level of accuracy, and can be simply measured in newborns (and their mothers) using minimally invasive methods.
New research from Cornell University shows the more alcohol ads someone was exposed to, the more likely they were to report consuming at least one alcoholic drink in the previous month. And among drinkers, exposure to more ads correlated to consuming more drinks.
Routine screening for risky alcohol use in general practice can identify people who may benefit from simple interventions to reduce consumption. However, the optimal time interval for repeat screening, including for those who have screened negative, is uncertain. A new study published in Alcoholism: Clinical and Experimental Research has revealed that, for a significant minority of the population, alcohol risk status can change from ‘low risk’ to ‘at-risk’ (or vice versa) within one year – potentially complicating the interpretation of infrequent screening tests.
Mojito, appletini or a simple glass of fizz – they may take the edge off a busy day, but if you find yourself bingeing on more than a few, you could be putting your physical and mental health at risk according new research at the University of South Australia.
Is the lockdown leading us to drink more alcohol or spend more time gambling online or watching pornography? Researchers today launch a survey aimed at tracking how our habits have changed in response to our forced isolation.
Rates of alcohol use disorder (AUD) have risen in the US in recent years. A small number of pharmacotherapies (drug treatments) are available for AUD, but there is an urgent need for more treatments to be evaluated. Increasingly, novel medications, as well as behavioral interventions, are tested in laboratory-based studies, where the impact on participants’ alcohol consumption can be directly assessed. However, it is not known if drinking in the laboratory setting accurately reflects individuals’ real-life drinking behavior and therefore if study findings hold true in the real-world. A new report in the journal Alcoholism: Clinical and Experimental Research by researchers from the NIAAA-supported Center for the Translational Neuroscience of Alcoholism at Yale University addresses this issue, by examining the extent to which individuals’ drinking in a laboratory setting correlates with their (self-reported) alcohol use in the lead-up to the study.
Functional MRI (fMRI), a type of scan that measures brain activity, has enabled study of the impact of alcohol on brain function. This type of imaging allows brain activity to be assessed while participants are at rest, performing a simple task like tapping a finger, or doing a complex cognitive task like a memory task or decision-making. It works by detecting the change in blood flow that occurs when brain cells (or neurons) in different parts of the brain are activated. Blood flow provides the energy and oxygen needed for brain cells to activate, and it is this exchange of oxygen that is measured using fMRI and is reflected by brain blood flow. Complicated physics are involved in determining the profile of blood flow when a part of the brain is activated, and studies have shown that the time course of these changes – known as the hemodynamic response function (HRF) – is affected by acute alcohol consumption. However, the effects of heavy chronic (long-term) alcohol consumption on HRF
A new study at The University of Texas at El Paso will look at the psychological factors that led some Hispanic men to successfully change their heavy drinking behavior in order to help others make similar changes. The study begins during Alcohol Awareness Month.
O número de pessoas desabrigadas tornou-se uma crise social e um problema de saúde pública no mundo todo, afetando pessoas de todas as idades. A maioria das pessoas desabrigadas está em desvantagem, tendo poucos recursos, e podem ou não ter um seguro de saúde adequado.
صار التشرد أزمة اجتماعية ومشكلة صحية عامة حول العالم، ما يؤثر على الناس من جميع الأعمار. معظم المشردين متضررون ويحظون بالقليل من الموارد، وربما يتمتعون أو لا يتمتعون بتأمين صحي كافٍ. المرض العقلي ومعاقرة المخدرات أو الكحول من المشاكل الشائعة في مجتمع المشردين. واحتمالية إصابة من يعيشون في الشوارع بمرض القلب كبيرة. بل وقدرتهم على رعاية صحتهم قليلة كذلك.
The consequences of prenatal alcohol exposure have been highlighted by three new reports on fetal alcohol spectrum disorders (FASD) in a virtual issue of the journal Alcoholism: Clinical & Experimental Research. FASD is the umbrella term for the continuum of effects caused by prenatal drinking, encompassing the most severe form, fetal alcohol syndrome (FAS), and less severe forms including partial fetal alcohol syndrome (pFAS) and alcohol-related neurodevelopmental disorder (ARND). Children with FAS have poor growth, atypical facial features, and central nervous system problems, and all three conditions require evidence of neurobehavioral impairment for diagnosis.
A well-known hangover drug not only helps soothe pounding headaches but also triggers profound changes that protect the liver, USC scientists report in new findings that could help prevent alcohol-related harm.
While it may be tempting to drink more while quarantined at home, a Loyola Medicine doctor is urging moderation, as too much alcohol can diminish the body’s ability to fight off infections like COVID-19.Majid Afshar, MD, a pulmonologist and critical care specialist and assistant professor at Loyola University Chicago Stritch School of Medicine, has studied the effects of alcohol on the body’s immune system, as well as its impact on breathing and lung health. He warns that excessive alcohol use (at least four or five drinks over a few hours) can alter our cytokine response, or signaling proteins, which regulate the body’s immune response.
Cannabis use can worsen some consequences of alcohol use among young adult drinkers over time, according to a new study which tracked the frequency of cannabis use and negative drinking outcomes among college students over three years. More than one in five young drinkers use cannabis, often (but not always) at the same time as drinking alcohol. This is a concern because the effects of cannabis might combine with those of alcohol to increase negative outcomes of drinking, such as impaired driving or developing an alcohol use disorder Although previous research has suggested a link between cannabis use and alcohol consequences, there have been few long-term evaluations of the impact of fluctuations in cannabis use on alcohol consequences over time. The latest study, published in the journal Alcoholism: Clinical and Experimental Research, was conducted by researchers in Toronto, Ontario, and Buffalo, New York.
Drinking alcoholic beverages may be more appealing amid unease about the coronavirus, as people deal with shelter-at-home orders, fears about the economy and boredom, says a Baylor University researcher who studies alcohol use and misuse. But with regulations providing less access to alcohol, this may be a good time for individuals struggling with alcohol use to begin recovery and for others to guard against over-relying on alcohol or other substances.
Fetal alcohol spectrum disorders (FASD) describe the range of effects associated with prenatal alcohol exposure (PAE). The most severe forms of FASD are fetal alcohol syndrome (FAS) and partial fetal alcohol syndrome (PFAS), which have adverse effects on learning and memory and result in observable physical abnormalities, including a distinct pattern of facial dysmorphic features, small head circumference, and growth restriction. Identifying the specific brain regions affected is important to fully understand the impact of PAE. Poor spatial skills are common in children with FASD, and tests of navigation in rodents – and more recently, humans – have linked PAE to impairment in ‘place learning’ (the learning of physical positions or locations of objects). Place learning in rodents and humans depends on the hippocampus, a small seahorse-shaped structure in each side of the brain. The hippocampus is particularly sensitive to PAE and is smaller in people (and rodents) exposed to alcohol in
Alcoholics Anonymous, the worldwide fellowship of sobriety seekers, is the most effective path to abstinence, according to a comprehensive analysis conducted by a Stanford School of Medicine researcher and his collaborators.
Drinking while pregnant can harm the developing fetus, leading to physical, cognitive, and neurobehavioral effects that may persist into adulthood. No safe level of alcohol in pregnancy has been identified, and many guidelines now recommend total abstinence. However, prenatal drinking remains common, particularly early on before women are aware of their pregnancy.
Alcohol use disorder (AUD) is more common among people who have another, co-occuring psychiatric condition (e.g., depression or ADHD), and vice versa. These links are well established, and are based on meeting diagnostic criteria for one or other disorder. However, investigating associations based on strict ‘yes/no’ diagnoses does not account for people who may have a range of psychiatric symptoms and yet do not meet the threshold for a diagnosis of any single disorder.
Adolescents’ expectations of drinking – whether they anticipate having positive or negative experiences with alcohol – are an important influence on their drinking behavior. For example, those with stronger ‘positive expectancies’ are more likely to start drinking at a young age and to have problems with alcohol. Parental drinking can be an important factor in shaping alcohol expectancies in early adolescence, before a young person starts using alcohol. Studies indicate that children of parents with high levels of alcohol use, and/or an alcohol use disorder (AUD), tend to have stronger positive expectancies of alcohol. However, some evidence suggests that observing the undesirable effects of their parents’ high-risk drinking could lead to ‘negative expectancies’, although this link is uncertain. Researchers from Arizona State University have conducted a new study, published in the journal Alcoholism: Clinical and Experimental Research, assessing whether the observable negative effects
Adolescents who are bullied about their weight or body shape may be more likely to use alcohol or marijuana than those who are not bullied, according to new research published by the American Psychological Association.
New research shows that two brain proteins help regulate fat accumulation in the liver associated with excessive alcohol consumption, specifically binge drinking. The study is published ahead of print in the American Journal of Physiology—Endocrinology and Metabolism.
Exposure to alcohol advertising changes teens’ attitudes about alcohol and can cause them to start drinking, finds a new analysis led by NYU School of Global Public Health and NYU Grossman School of Medicine. The study, which appears in a special supplement of the Journal of Studies on Alcohol and Drugs funded by the National Institute on Alcohol Abuse and Alcoholism, uses a framework developed to show causality between tobacco advertising and youth smoking and applies it to alcohol advertising.
Alcohol misuse is common among adolescents, and increases the risk of developing a chronic alcohol use disorder (AUD) in the future. Adolescents respond differently to alcohol compared with adults — they tend to be less sensitive to some of the negative effects of drinking that help protect against excessive intake, but more sensitive to its rewarding and memory-impairing effects. This may contribute to the high rates of alcohol misuse in adolescence, as well as to an elevated risk of developing AUD. However, as not all adolescents who drink alcohol will develop an AUD, it is important to identify factors that may further increase propensity to abuse alcohol in this age-group. Researchers from the State University of New York at Binghamton are interested in the potential impact of having a general anaesthetic, in view of evidence that exposure to anesthesia in adolescence can cause behavioral alterations similar to those induced by alcohol. In a new study published in the journal Alcoh
Women aged 50-70 are more likely than younger women to consume alcohol at levels that exceed low risk drinking guidelines - and most think that's just perfectly fine.
Laws can have important effects on public health risks and outcomes, while research can provide key evidence to inform effective health-related laws and policies. An introduction to the increasingly influential field of legal epidemiology is presented in a special supplement to the Journal of Public Health Management and Practice (JPHMP). The journal is published in the Lippincott portfolio by Wolters Kluwer.
Simultaneous use of alcohol and marijuana (SAM) is common among young people, and is sometimes a deliberate choice to enhance the effects of intoxication. However, compared with alcohol use alone, SAM has been linked to a greater risk of interpersonal problems, physical and mental health issues, and road accidents. Despite this, there has been little research at the occasion level – for example, it is not known if individuals who engage in SAM drink more (or less) alcohol on the occasions when they also use marijuana, and experience more (or fewer) alcohol-related consequences, than on alcohol-only days. Researchers in Seattle and Minneapolis have conducted a new study, published in the journal Alcoholism: Clinical and Experimental Research, to evaluate these aspects, by conducting multiple daily assessments of alcohol and SAM use among the same individuals over time. The study took place in and around Seattle in Washington state, where non-medical marijuana use is legal for those over
A new service model for addiction recovery support combines voluntary peer-led initiatives with professional support, providing flexible community-based options to address barriers to sustained recovery. Recovery Community Centers (RCCs) are one of the most common and rapidly expanding examples of this model in the US. RCCs function as recovery hubs for people with substance use disorder, offering a range of support services on the principle that sustained recovery requires not only detoxification and mental health support, but also personal, social, environmental, and cultural resources. Collectively, these resources have been termed ‘recovery capital’. The idea is that boosting an individual’s recovery capital will lead to improvements in quality of life, functioning, and well being that support long-term remission from addiction. However, RCCs have not yet been widely studied, and little is known about their user-base and impact. A new study published in the journal Alcoholism: Cli
For people with psychiatric disorders, comorbidity — or the presence of two or more disorders in a single patient — is quite common. One of the most common comorbidities is alcohol use disorder and major depressive disorder. In fact, people with alcohol use dependence are almost four times more likely to also have a major depressive disorder.
Every day nearly 200 people die from an overdose of drugs or from alcohol poisoning, with opioids responsible for the majority. Recognizing the signs and knowing how to respond to medical emergencies, including carrying and administering naloxone in cases of opioid overdose, can save lives says the ASA.
McMaster University researchers surveyed the data of patients of Hamilton’s two hospital systems over nine years and found 52 with low Vitamin C levels. This included 13 patients who could be diagnosed as having scurvy, and an additional 39 who tested positive for scurvy but did not have documented symptoms.
Among those with scurvy, some were related to alcohol use disorder or to bariatric surgery but the majority were related to other causes of malnutrition such as persistent vomiting, purposeful dietary restrictions, mental illness, social isolation and dependence on others for food.
Using novel imaging technologies, researchers produce first whole-brain atlas at single-cell resolution, revealing how alcohol addiction and abstinence remodel neural physiology and function in mice.
Binge drinking is a common and harmful pattern of alcohol use, often defined as consuming at least four (for women) or five (for men) drinks in one drinking episode. However, some people drink well beyond this, consuming two or even three times the binge threshold, putting them at very high risk of acute harm. Previous research on such ‘high-intensity drinking’, or ‘HID’, has been mostly limited to college-age youth, with less known about HID in the mid-adult age group. A new study published in the journal Alcoholism: Clinical and Experimental Research has evaluated the prevalence, consequences, and influences of HID among Australian adults of working age.
Alcohol misuse among college students remains a major public health concern. Students’ perceptions of how much their peers are drinking, and of peers’ attitudes to alcohol, are known to be a key influence on their own alcohol use. Two distinct types of social norms that can shape students’ drinking are recognized – ‘injunctive’ norms, namely perceptions of peers’ attitudes about how much a college student should drink, and ‘descriptive’ norms, which are perceptions of how much their peers do drink.
Rates of heavy drinking and alcohol use disorder peak in the late adolescent and early adult age-group (19-25 years), before decreasing from around age 26. This supports the notion that many young people ‘mature out’ of heavier drinking behavior. However, changes in young adults’ alcohol consumption vary widely, and depend on a range of factors including role transitions (e.g. marriage, parenthood), social networks, and personality. Dr. Michael Windle from Emory University, Georgia, assessed the variation in ‘maturing out’ by evaluating trajectories of alcohol use from adolescence through young adulthood, up to around 33 years of age. The study, published in the journal Alcoholism: Clinical and Experimental Research, also explored whether different alcohol use trajectories were associated with other indicators of young-adult functioning, relating to health, sleep, and social and occupational functioning.
New research JNCCN—Journal of the National Comprehensive Cancer Network, using data from NHIS to examine self-reported drinking habits among people reporting a cancer diagnosis, finds 56.5% were current drinkers, 34.9% exceeded moderate drinking levels, and 21% engaged in binge drinking.
A study published in the journal Alcoholism: Clinical and Experimental Research could inform efforts to prevent adolescents from escalating to harmful patterns of drinking. Binge drinking in adolescence has many short- and long-term heath consequences, including risk of future alcohol use disorder and potential for harm to the developing brain. The risks are greatest for those who binge frequently – at least once a week. A hallmark of binge drinking is a reduced capacity to control one’s alcohol intake, related to a neurological process of ‘inhibitory control’ involving several regions of the brain. In adolescents who have not yet started drinking, specific alterations in these brain responses have been linked to an increased risk of future alcohol and drug use; however, it was not known if there are changes that could predict escalation of alcohol use among those already drinking. Therefore, researchers from the University of California investigated whether abnormal brain patterns co
