INTRODUCTION: Energy drinks are popular beverages that are supposed to counteract sleepiness, increase energy, maintain alertness and reduce symptoms of hangover. Cognitive enhancing seems to be related to many compounds such as caffeine, taurine and vitamins. Currently, users mostly combine psychostimulant effects of energy drinks to counteract sedative effects of alcohol. However, recent literature suggests that this combination conducts to feel less intoxicated but still impaired. The goal of the present article is to review cognitive impact and subjective awareness in case of caffeinated alcoholic beverage (CAB) intoxication...

Riding a bicycle under the influence of alcohol is illegal in Japan. Nevertheless, intoxicated bicyclists are frequently treated at hospital emergency departments for bicycle-related injuries. This patient population usually requires more hospital resources, even for relatively minor injuries. Therefore, we hypothesized that bicycle-related crashes involving bicyclists under the influence of alcohol cost more to treat than those that do not involve alcohol intoxication. The aim of the present study was to examine the costs associated with bicycle-related minor injuries and alcohol intoxication of the bicyclist...

Alcohol overconsumption as a worldwide issue results in alcoholic liver disease (ALD), such as steatosis, alcoholic hepatitis and cirrhosis. The treatment of ALD has been widely investigated but remains challenging. In this work, the protective effects of graphene oxide quantum dots (GOQDs) as novel nanozymes against alcohol overconsumption are discovered, and the specific mechanisms underlying these effects are elucidated via omics analysis. GOQDs dramatically alleviate the reduction of cell viability induced by ethanol and can act as nanozymes to accelerate ethanol metabolism and avoid the accumulation of toxic intermediates in cells...

Enzymatic activity of Ca2+-dependent calpain proteases as well as the content and gene expression of μ-calpain (activated by micromolar calcium ion concentrations), calpastatin (inhibitor of calpains), and titin (substrate for calpains) were investigated in cardiac muscles of rats subjected to chronic alcoholization for 3 and 6 months. There was no increase in the "heart weight/body weight" parameter indicating development of heart hypertrophy in the alcoholized rats, while a decreasing trend was observed for this parameter in the rats after 6-month modeling of alcoholic cardiomyopathy, which indicated development of atrophic changes in the myocardium...

OBJECTIVE: Research demonstrates alcohol temporally precedes and increases the odds of violence between intimate partners. However, despite an extensive theoretical literature on factors that likely moderate the relationship between alcohol and dating violence, minimal empirical research has examined such moderators. METHOD: The purpose of the present study was to examine two potential moderators of this association: trait anger and partner-specific anger management...

OBJECTIVE: Overservice of alcohol (i.e., selling alcohol to intoxicated patrons) continues to be a problem at bars and restaurants, contributing to serious consequences such as traffic crashes and violence. We developed a training program for managers of bars and restaurants, eARM™, focusing on preventing overservice of alcohol. The program included online and face-to-face components to help create and implement establishment-specific policies. METHOD: We conducted a large, randomized controlled trial in bars and restaurants in one metropolitan area in the midwestern United States to evaluate effects of the eARM program on the likelihood of selling alcohol to obviously intoxicated patrons...

AIMS: Positive family history of alcohol use disorder (FHP), a variable associated with propensity for alcohol use disorder (AUD), has been linked with elevated hangover frequency and severity, after controlling for alcohol use. This implies that hangover experiences may be related to AUD. However, inadequate control of alcohol consumption levels, low alcohol dose and testing for hangover during the intoxication phase detract from these findings. Here, we present further data pertinent to understanding the relationship between family history and alcohol hangover...

BACKGROUND: The term Alcohol Use Disorder (AUD) incorporates different states of disease related to the recurrent use of alcohol and linked to the relevant impairment, disability and failure to perform major responsibilities in different realms. Many neurotransmitter systems are involved in the phases or states of alcoholism from reward mechanisms, associated to binge intoxication, to stress and anxiety linked to relapse and withdrawal. Some neuropeptides play a key function in the control of anxiety and stress, and establish a close relationship with the pathological mechanisms underlying alcohol addiction...

Frostbite can lead to severe consequences including loss of digits and limbs. One of the mechanisms of frostbite includes vascular thrombosis. The use of tissue plasminogen activator (tPA) in frostbite has been shown to be effective in case reports and small prospective studies. A retrospective chart review was performed on all patients admitted for frostbite between January 2008 and April 2015, and six patients were identified as having received treatment with intravenous tPA. Patients received an initial bolus dose followed by a 6-hour infusion of tPA...

BACKGROUND: The theory of behavioral tolerance to alcohol posits that greater experience with drinking to intoxication leads to less impaired cognitive and psychomotor performance. However, the degree to which behavioral tolerance develops or changes over time in adults due to repeated heavy alcohol drinking has not been clearly demonstrated. METHOD: We examined data from the first 6 years of the Chicago Social Drinking Project to test whether chronic heavy drinkers (HDs; n = 86) and light drinkers (LDs; n = 69) exhibit behavioral tolerance or changes in perceived impairment at two testing phases in early adulthood...

OBJECTIVES: Lollapalooza (LP) is an annual 3-day outdoor music festival in Chicago. Underage drinking and drug use are believed to be common, but the burden on emergency departments (EDs) has not been documented. We assessed the burden on health care resources associated with this music festival. METHODS: We performed a retrospective chart review of adolescent (aged 11-20 years) ED visits during LP weekend and 4 summer comparison weekends at Lurie Children's Hospital in Chicago, Ill, in 2014 (n = 356)...

BACKGROUND: Negative physiological stimulation and sedation side effects are experienced by a significant proportion of consumers who consume alcohol mixed with energy drinks (AmED). Few studies have compared the frequency of side effects between sessions of AmED and sessions of alcohol only within-subject, and none have explored a dose relationship. OBJECTIVES: Explore the occurrence of self-reported physiological stimulant and sedative side effects between sessions of AmED and alcohol only, and at varying ED dosage levels within AmED sessions...

BACKGROUND: A functional polymorphism within the mu-opioid receptor (OPRM1) gene, rs1799971 (A118G), previously has been associated with measures of alcohol use and sensitivity to its effects, but findings have been inconclusive. A recent study suggested that a second nearby variant within OPRM1, rs3778150, is robustly associated with heroin dependence, and fully explained a smaller observed association with rs1799971. Given evidence that the rs3778150-C allele is associated with decreased OPRM1 expression levels in the human brain, the current study sought to test the hypothesis that rs3778150 represents a causal variant within OPRM1 that increases risk for a variety of alcohol use phenotypes...

Introduction. Medical preparedness at mass gatherings is challenging, as little is known about the optimal planning. Most studies and case reports are based on mass casualty incidents, so the results cannot be extrapolated to mass gatherings. Aim of this study was to evaluate the preclinical medical structure and the frequency of specific injuries and medical emergencies during the event. Methods. Retrospective analysis of a prospectively collected database. Three on-site medical assistance points were set up, completed by mobile teams, and coordinated by an on-site operational management team...

BACKGROUND: Injuries result in 5.8 million global fatalities annually and are the leading cause of death in younger individuals. Nevertheless, population-based autopsy investigations on traumatic deaths are scarce. We set out to study all consecutive autopsies on traumatic fatalities performed in a 5-year time segment in Estonia. METHODS: After the ethics review board approval, all consecutive autopsies after blunt or penetrating deaths occurring in prehospital or in-hospital settings between January 1, 2009, and December 31, 2013, were retrospectively reviewed using the National Forensic Medicine Database...
