Intention to reduce drinking alcohol and preferred sources of support: An international cross-sectional study

Introduction. Drinking alcohol is legal in most countries of the world. Given the social acceptance of this behavior despite potential negative impact on health, help-seeking behavior could differ when compared to other drugs. This paper aimed to assess intentions to reduce drinking and the preferred sources of support among a large international sample of people who drink alcohol. Materials and methods. The Global Drug Survey (GDS) is the world’s largest annual survey of drug use. This paper included data from 82,190 respondents from 12 countries on four continents who reported the use of alcohol in the last 12 months, collected during November 2016 - January 2017 (GDS2017). Results. Overall, 34.8% said they would like to drink less in the following 12 months and 7.6% said they would like help to drink less. Online tools were the preferred source of support to reduce drinking by respondents from Australia, New Zealand, and the UK, those with low AUDIT scores and without a mental health condition. Specialist counselling was most preferred by those from Germany, Switzerland, and Denmark and those with high AUDIT scores, not educated to degree level and with a mental health condition. Conclusion. Interest in online interventions for harmful drinking is significant and highest among people who drink at low risk. Online tools should offer brief screening and feedback, ensuring that people with high risk drinking patterns are referred to more specialist services

In vitro and in vivo anti-epileptic efficacy of eslicarbazepine acetate in a mouse model of KCNQ2-related self-limited epilepsy

Background and purpose: The KCNQ2 gene encodes for the Kv 7.2 subunit of non-inactivating potassium channels. KCNQ2-related diseases range from autosomal dominant neonatal self-limited epilepsy, often caused by KCNQ2 haploinsufficiency, to severe encephalopathies caused by KCNQ2 missense variants. In vivo and in vitro effects of the sodium channel blocker eslicarbazepine acetate (ESL) and eslicarbazepine metabolite (S-Lic) in a mouse model of self-limited neonatal epilepsy as a first attempt to assess the utility of ESL in the KCNQ2 disease spectrum was investigated. Experimental approach: Effects of S-Lic on in vitro physiological and pathological hippocampal neuronal activity in slices from mice carrying a heterozygous deletion of Kcnq2 (Kcnq2+/- ) and Kcnq2+/+ mice were investigated. ESL in vivo efficacy was investigated in the 6-Hz psychomotor seizure model in both Kcnq2+/- and Kcnq2+/+ mice. Key results: S-Lic increased the amplitude and decreased the incidence of physiological sharp wave-ripples in a concentration-dependent manner and slightly decreased gamma oscillations frequency. 4-Aminopyridine-evoked seizure-like events were blocked at high S-Lic concentrations and substantially reduced in incidence at lower concentrations. These results were not different in Kcnq2+/+ and Kcnq2+/- mice, although the EC50 estimation implicated higher efficacy in Kcnq2+/- animals. In vivo, Kcnq2+/- mice had a lower seizure threshold than Kcnq2+/+ mice. In both genotypes, ESL dose-dependently displayed protection against seizures. Conclusions and implications: S-Lic slightly modulates hippocampal oscillations and blocks epileptic activity in vitro and in vivo. Our results suggest that the increased excitability in Kcnq2+/- mice is effectively targeted by S-Lic high concentrations, presumably by blocking diverse sodium channel subtypes

Emergency Department Chief Complaint and Diagnosis Data to Detect Influenza-Like Illness with an Electronic Medical Record

Background: The purpose of syndromic surveillance is early detection of a disease outbreak. Such systems rely on the earliest data, usually chief complaint. The growing use of electronic medical records (EMR) raises the possibility that other data, such as emergency department (ED) diagnosis, may provide more specific information without significant delay, and might be more effective in detecting outbreaks if mechanisms are in place to monitor and report these data.Objective: The purpose of this study is to characterize the added value of the primary ICD-9 diagnosis assigned at the time of ED disposition compared to the chief complaint for patients with influenza-like illness (ILI).Methods: The study was a retrospective analysis of the EMR of a single urban, academic ED with an annual census of over 60, 000 patients per year from June 2005 through May 2006. We evaluate the objective in two ways. First, we characterize the proportion of patients whose ED diagnosis is inconsistent with their chief complaint and the variation by complaint. Second, by comparing time series and applying syndromic detection algorithms, we determine which complaints and diagnoses are the best indicators for the start of the influenza season when compared to the Centers for Disease Control regional data for Influenza-Like Illness for the 2005 to 2006 influenza season using three syndromic surveillance algorithms: univariate cumulative sum (CUSUM), exponentially weighted CUSUM, and multivariate CUSUM.Results: In the first analysis, 29% of patients had a different diagnosis at the time of disposition than suggested by their chief complaint. In the second analysis, complaints and diagnoses consistent with pneumonia, viral illness and upper respiratory infection were together found to be good indicators of the start of the influenza season based on temporal comparison with regional data. In all examples, the diagnosis data outperformed the chief-complaint data.Conclusion: Both analyses suggest the ED diagnosis contains useful information for detection of ILI. Where an EMR is available, the short time lag between complaint and diagnosis may be a price worth paying for additional information despite the brief potential delay in detection, especially considering that detection usually occurs over days rather than hours.

Where and what you drink is linked to how much you drink: A survey of alcohol use in 17 countries

Background:  This paper aimed to explore the differences in subjective experiences of intoxication depending on drinking location and drink type. Methods: Data came from 32,194 respondents to The Global Drug Survey (GDS) 2015, an annual, cross-sectional, online survey. Respondents selected their usual drinking location (home alone: home with partner/family: house parties: pubs/bars or clubs) and usual drink (wine; beer/cider/lager; spirits or alcopops/coolers). They indicated how many drinks they required to reach three stages of intoxication (feeling the effects; an ideal stage of intoxication; and the tipping point) and how frequently they reached each stage. Results: Drink type affected grams of alcohol reported to reach the tipping point: 109gm wine, 127gm alcopops, 133gm of beer, and 134gm of spirts. Respondents who drank at home alone, or in clubs reached their tipping point more frequently compared to other locations. Conclusions: Where people drink, and the type of alcohol they drink, affected the amount of alcohol reported to reach different stages of intoxication. Understanding why different drinking locations, and drink types lead to a need for greater consumption to reach an ideal state of drunkenness, such as social cues from other people who drink, may enable people to reduce their drinking

Drinking to excess and the tipping point: An international study of alcohol intoxication in 61,000 people

Background: People who drink alcohol often seek to manage their intake in order to maximise the pleasurable effects, such as feelings of sociability and relaxation, without reaching their ‘tipping point’, where they feel out of control, or unwell. This paper aimed to explore three stages of intoxication; feeling the effects; being as drunk as you would like to be; and reaching the tipping point (feeling more drunk than you want to be) in a large international sample. Methods: The Global Drug Survey (GDS) is an annual, cross-sectional, online survey of drug use. This paper draws on data from 61,043 respondents (63.7% male) from 21 countries who took part in GDS2015 collected in November 2014 to January 2015. Respondents reported their usual type of drink; how many drinks they would require to reach each stage of intoxication and how frequently they reached each stage. Alongside socio-demographic measures, they also completed the Alcohol Use Disorders Identification Test (AUDIT). Results: Male respondents reported consuming 87.55gm to be as drunk as they want to be and female respondents reported 70.16gm, on average. The tipping point was reached at 138.65gm for male respondents and 106.54 gm for female respondents. Overall 20.3% reported reaching their tipping point at least once a month. Being male, aged under 25 and at higher risk for alcohol use disorder was associated with reporting reaching the tipping point more frequently. Conclusions: The amount of alcohol being consumed to reach a desired point of intoxication is much higher than the maximum daily, and sometimes weekly, amount recommended by country guidelines. Encouraging people to avoid reaching their tipping point may be a useful intervention point alongside better communication of low risk drinking guidelines

Comparing transgender and cisgender experiences of being taken advantage of sexually while under the influence of alcohol and/or other drugs

A small body of literature suggests that transgender people are more frequently exposed to sexual violence while they are under the influence of alcohol than cisgender counterparts. The goal of this study was to report any differences between transgender (n=1,136) and cisgender (n=74,277) respondents to the Global Drug Survey on their experiences of being taken advantage of sexually while under the influence of alcohol and/or other drugs. We found that transgender people were more likely than cisgender people to have experienced being taken advantage of in the last year (9.3% vs 4.2%) and more than 12 months preceding the survey (24.9% vs 14.3%). Non-binary participants were more likely than binary transgender participants (27.7% vs 17.8%) to report being taken advantage of sexually more than a year preceding the survey. Similarly, trans respondents assigned female at birth were more likely than trans respondents assigned male at birth to report this (30.0% vs 19.7%). Non-specialist services for survivors of sexual violence should be adequately prepared for and accommodating towards transgender clients. Future research should explore their unique needs. Moreover, clinicians who assess transgender people should remain mindful of their increased likelihood of being taken advantage of sexually while under the influence of alcohol and other drugs and consider trauma-informed interventions
