Excessive alcohol consumption is an established risk factor for atrial fibrillation (AF), but what are the effects of moderate and mild consumption on AF? In a new study published in HeartRhythm Australian researchers showed that regular moderate alcohol consumption (an average of 14 glasses per week) results in more electrical evidence of scarring and impairments in electrical signaling compared with non-drinkers and light drinkers. Alcohol consumption is therefore an important modifiable risk factor for AF.
Academics at the University of Warwick have found that low functional connectivity of the lateral orbitofrontal cortex that is associated with the tendency to smoke is associated with increased impulsiveness -- which may contribute to the tendency to smoke. The high connectivity of the reward-related medial orbitofrontal cortex in drinkers may increase the tendency to be attracted to the reward of alcohol consumption.
Adults in South Africa consume more alcohol than adults in most other countries; previous research has shown this comes with high rates of fetal alcohol syndrome and is a driver of the country's leading causes of death: sexually transmitted infections and interpersonal violence.
A new study from researchers from the University of North Carolina at Chapter Hill in the Gillings School of Global Public Health and the Prevention Research Center of the Pacific Institute for Research and Evaluation in Berkeley, California, examines the proportions of AIAN who seek treatment for lifetime alcohol use disorder and the characteristics associated with those who seek treatment.
New research shows that taking part in Dry January sees people regaining control of their drinking, having more energy, better skin and losing weight. They also report drinking less months later.
Having seven or fewer alcoholic drinks a week was associated with increased survival in older adults with newly diagnosed heart failure compared with patients who abstained from alcohol after accounting for other potential mitigating factors. Conflicting data exist about an association between alcohol consumption and heart failure but not much is known about the safety of alcohol consumption in patients after a new diagnosis of heart failure.
A new study suggests that people over age 65 who are newly diagnosed with heart failure can continue to drink moderate amounts of alcohol without worsening their condition. However, the findings do not suggest that nondrinkers should start imbibing after a heart failure diagnosis, the researchers emphasized.
New research has found that heavy drinkers who are trying to stop smoking may find that reducing their alcohol use can also help them quit their daily smoking habit. Heavy drinkers' nicotine metabolite ratio -- a biomarker that indicates how quickly a person's body metabolizes nicotine -- reduced as they cut back on their drinking.
Taking antidepressants for depression, having post-traumatic stress disorder or anxiety diagnosed by a doctor are risk factors for a disruptive and sometimes violent sleep disorder called rapid eye movement (REM) sleep behavior disorder, according to a study published in the Dec. 26, 2018, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study also found men are more likely to have the disorder.
College students who binge drink are frequently posting on social media while intoxicated and show signs of social media "addiction," according to a new study.
