Alcohol intoxication is usually associated with drowning, falls, overdoses, fires, occupational accidents, physical and sexual abusements, domestic violence and traffic accidents. Therefore, alcohol considered an important factor for the explanation of the occurrence of many types of injuries. For many purposes such as forensic, it is important to establish a detection method to ensure whether the subject or the patient have consumed alcohol at a level that would be the reason for the accidents or injuries occur. Therefore, in this work, a simple, rapid and low-cost method was developed and validated for the detection of the alcohol in saliva as a function of blood alcohol concentration (BAC). The method is based on fabricated a biosensor consisted of chromium oxide nanoparticles deposited on filter paper. The validation of the biosensor was tested on 50 participants which categories into two selected groups (1 and 2). Group 1 consisted of 20 subjects from an organized party (no alcohol), they usually consumed three to four drinks as an average per week while Group 2 consisted of 30 subjects from an organized party the local bar (alcohol group), usually consumed two to three drinks per day. The results of the present study have shown that 95% of group 1 demonstrated positive results with variable colour intensities of the BAC in comparison to the 80% only of subjects from group 2. The present study has approved that the fabricated biosensor can effectively detect 0.02% or more of BAC which can be a useful test for many purposes such as medical, forensic, research and workplace.

Studies have demonstrated significant sex differences in alcohol intoxication effects. In contrast, the majority of studies on the alcohol hangover phase did not investigate sex differences. Therefore, the current study examined possible sex differences in the presence and severity of alcohol hangover symptoms. Data from n = 2446 Dutch students (male = 50.7%, female = 49.3%) were analyzed. They reported the presence and severity of 22 hangover symptoms experienced after their past month heaviest drinking occasion. Subjects were categorized according to their estimated peak blood alcohol concentration (eBAC) and presence and severity of the hangover symptoms were compared between men and women. In the lowest eBAC group (0% ≤ eBAC < 0.08%), no significant sex differences were found. In the subsequent eBAC group (0.08% ≤ eBAC < 0.11%), severity of nausea was significantly higher in women than in men. In the third eBAC group (0.11% ≤ eBAC < 0.2%), women reported higher severity scores on nausea, tiredness, weakness, and dizziness than men. Men reported the presence of confusion significantly more often than women, and women reported the presence of shivering significantly more often than men. In the fourth eBAC group (0.2% ≤ eBAC < 0.3%), women reported higher severity scores on nausea and tiredness than men. In the highest eBAC group (0.3% ≤ eBAC < 0.4%), no significant sex differences were found. In conclusion, across the eBAC groups, severity scores of nausea and tiredness were higher in women than in men. However, albeit statistically significant, the observed sex differences in presence and severity of hangover symptoms were of small magnitude, and therefore, have little clinical relevance.

Endogenous alcohol has been applied for spontaneous ethanol production via different metabolic pathways of the human body. Auto-brewery syndrome describes the patients with alcohol intoxication after ingesting carbohydrate-rich meals. The main objective of this study is to investigate the effect of diabetes mellitus (DM), liver cirrhosis (LC) and presence of both (DM and LC) on blood alcohol concentration (BAC) especially after carbohydrate ingestion. BAC has been measured by headspace gas chromatography-mass spectrometry in three groups of humans namely control, DM, LC and both (DM and LC) groups. The results showed that BAC in control group was 0.01–.3 mg/dL with mean 0.3 ± 0.41 mg/dL. In patients with DM, BAC is significantly higher than that of control group 4.85 ± 3.96 mg/dL. In patients with LC, BAC was 3.45 ± 2.65 mg/dL. In patients with both DM and LC, BAC increases to reach 10.88 ± 5.36 mg/dL. Endogenous ethanol production appears to increase in DM and LC. Also, it increased much more in patients with both diseases, but it did not reach toxic levels. On comparing BAC and blood glucose level in each group, all groups show insignificant correlations ( p > 0.05).

The purpose of this paper is to investigate the existence of stratification heterogeneity in traffic accidents in Shenzhen, what factors influence the casualties, and the interaction of those factors. Geographical detection methods are used for the analysis of traffic accidents in Shenzhen. Results show that spatial stratification heterogeneity does exist, and the influencing factors of fatalities and injuries are different. The traffic accident causes and types of primary responsible party have a strong impact on fatalities and injuries, followed by zones and time interval. However, road factors, lighting, topography, etc., only have a certain impact on fatalities. Drunk driving, speeding over 50%, and overloading are more likely to cause more casualties than other illegal behaviors. Speeding over 50% and speeding below 50% have significant different influences on fatalities, while the influences on injuries are not obvious, and so do drunk driving (Blood Alcohol Concentration ≥ 0.08) and driving under the influence of alcohol (0.08 > Blood Alcohol Concentration ≥ 0.02). Both pedestrians and cyclists violating the traffic law are vulnerable to fatality. Heavy truck overloading is more likely to cause major traffic accidents than minibuses. More importantly, there are nonlinear enhanced interactions between the influencing factors, the combination of previous non-significant factors and other factors can have a significant impact on the traffic accident casualties. The findings could be helpful for making differentiated prevention and control measures for traffic accidents in Shenzhen and the method selection of subsequent research.

Aims: Illegal substance use at music festivals is less documented than it is in nightlife and electronic dance music settings. This study investigated such use through questionnaires, breathalysers and oral fluid drug testing. We also examined the associations between testing positive for illegal substances and demographics, self-reported substance use and measured blood alcohol concentration levels. Methods: A cross-sectional study of 1,309 festival attendees from six Norwegian music festivals taking place between July and August 2016. Logistic regression models estimated the likelihood of a positive oral fluid drug test. Covariates were male, age, education, employment, smoking status, early age for alcohol intoxication, alcohol intoxication ⩾2 times a week, past-month and past-year illegal substance use, blood alcohol concentration levels and festivals. Results: Overall, 12% reported illegal substance use in the past 30 days and 11% tested positive for illegal substances. Cannabis (6%), cocaine (3%) and MDMA/ecstasy (2%) were most commonly detected. One-third had a blood alcohol concentration ⩾0.10%. Of those with a positive test result ( n=146), 95% had detectable alcohol levels and 41% had a blood alcohol concentration above 0.10%. Those studying or working part-time were less likely to test positive compared to those who were not employed. Furthermore, those reporting daily smoking and past-year cannabis or MDMA/ecstasy use were more likely to test positive, compared to those not reporting such use. Conclusions: Illegal substance use was less prevalent than in previous nightlife and electronic dance music studies. Almost all those testing positive for illegal substances had detectable alcohol levels and 41% had a blood alcohol concentration greater than 0.10%, possibly indicating combined use.

IntroductionIntoxications with alcohol are very frequent in clinical psychiatry and may lead to death depending on (maximum) blood alcohol concentration (BAC) and accompanying factors as liver function, tolerance, comedication, etc. Death may occur due to ethanol-induced respiratory depression and/or aspiration of gastric content (due to an impaired gag reflex); thus, securing of the airway and ventilation are occasionally necessary.Objectives/aimsTo illustrate the broad range of clinical outcomes of alcohol intoxications and their adequate therapy.MethodsWe present the case of a 58-year female patient with depression who demonstrated a very high BAC of 8.68 g/L (representing the highest survived BAC in literature) due to ingestion of large amounts of alcohol with suicidal intent.ResultsIntubation and ventilation were lifesaving and the patient did not develop any physical or mental consequential damage. As the patient had not regularly used alcohol or any other psychotropic agent tolerance could be ruled out.ConclusionsThis case emphasizes the necessity of rapid securing of the airway in patients with alcohol intoxication and respiratory depression and, furthermore, illustrates the large inter-individual differences regarding ethanol susceptibility.Disclosure of interestThe authors have not supplied their declaration of competing interest.

ABSTRACT Background Alcohol-induced hangover constitutes a significant, yet understudied, global hazard and a large socio-economic burden. Old folk wisdoms such as “Beer before wine and you'll feel fine; wine before beer and you'll feel queer” exist in many languages. However, whether these concepts in fact reduce hangover severity is unclear. Objectives The aim of this study was to investigate the influence of the combination and order of beer and wine consumption on hangover intensity. Methods In this multiarm, parallel randomized controlled matched-triplet crossover open-label interventional trial, participants were matched into triplets and randomly assigned according to age, gender, body composition, alcohol drinking habits, and hangover frequency. Study group 1 consumed beer up to a breath alcohol concentration (BrAC) ≥0.05% and then wine to BrAC ≥0.11% (vice versa for study group 2). Control group subjects consumed either only beer or only wine. On a second intervention day (crossover) ≥1 wk later, study-group subjects were switched to the opposite drinking order. Control-group subjects who drank only beer on the first intervention received only wine on the second study day (and vice versa). Primary endpoint was hangover severity assessed by Acute Hangover Scale rating on the day following each intervention. Secondary endpoints were factors associated with hangover intensity. Results Ninety participants aged 19–40 y (mean age 23.9), 50% female, were included (study group 1 n = 31, study group 2 n = 31, controls n = 28). Neither type nor order of consumed alcoholic beverages significantly affected hangover intensity (P > 0.05). Multivariate regression analyses revealed perceived drunkenness and vomiting as the strongest predictors for hangover intensity. Conclusions Our findings dispel the traditional myths “Grape or grain but never the twain” and “Beer before wine and you'll feel fine; wine before beer and you'll feel queer” regarding moderate-to-severe alcohol intoxication, whereas subjective signs of progressive intoxication were confirmed as accurate predictors of hangover severity. This trial was prospectively registered at the Witten/Herdecke University Ethics Committee as 140/2016 and retrospectively registered at the German Clinical Trials Register as DRKS00015285.

Introduction. Sudden natural death occurs unexpectedly in apparently healthy subjects, or in persons during an apparent benign phase in the course of disease. The most common cause is sudden cardiac death, which is sometimes the first and last manifestation of coronary heart disease. Alcohol directly influences excitation of myocytes, and therefore provokes arrhythmias and possibly, sudden cardiac death. Objective. To establish the frequency of sudden cardiac death in cases of acute alcohol intoxication, to determine blood alcohol concentration at the moment of death, and to determine frequency and level of ethanol intoxication in chronic alcohol abusers, as well as causes of sudden death in those cases. Method. Retrospective autopsy study was performed for a three-year-period. We analyzed cases of sudden natural death, in relation to age and gender, cause of death, and blood alcohol concentration (at least 0.5 g/L). We considered the person to be a chronic alcoholic abuser if gross examination of organs during autopsy showed changes typical for excessive and habitual alcohol consumption. Results. Our sample consisted of 997 cases: 720 men and 277 women, average age 62.0?15.2 years (min=11; max=98). Total of 753 of them died of sudden cardiac death: much more men (?2=167.364; p=0.000), significantly younger than women (t=6.203; p=0.000). We determined acute alcohol intoxication in 73 persons - average blood alcohol concentration 1.85?1.01 g/L (min=0.55; max=3.85), and 61 of them died of cardiovascular diseases (?2=236.781; df=5; p=0.000). Conclusion. In our observed sample, not many persons were under acute alcohol intoxication (around 7%). Most commonly, they were chronic alcohol abusers who died due to exacerbation of chronic heart disease, mildly or moderately intoxicated - the younger, the drunker.
