Alcohol and injuries: a review of international emergency room studies since 1995
ABSTRACT This paper provides a review of emergency room (ER) studies on alcohol and injury, using representative probability samples of adult injury patients, and focuses on the scope and burden of the problem as measured by estimated blood alcohol concentration (BAC) at the time of the ER visit, self-report drinking prior to injury, violence-related injury and alcohol use disorders. A computerized search of the English-language literature on MEDLINE, PsychINFO and the National Institute on Alcohol Abuse and Alcoholism (NIAAA) Alcohol and Alcohol Problems Science Database (ETOH) was conducted for articles published between 1995 and 2005, using the following key descriptors: (1) emergency room/emergency department/accident and emergency, (2) alcohol/drinking and (3) injuries (intentional and unintentional). Findings support prior reviews, with injured patients more likely to be positive for BAC and report drinking prior to injury than non-injured, and with the magnitude of the association substantially increased for violence-related injuries compared to non-violence-related injuries. Indicators of alcohol use disorders did not show a strong association with injury. Findings were not homogeneous across studies, however, and contextual variables, including study-level detrimental drinking pattern, explained some of the variation. This review represents a broader range of ER studies than that reported previously, across both developed and developing countries, and has added to our knowledge base in relation to the influence of contextual variables on the alcohol-injury relationship. Future research on alcohol and injury should focus on obtaining representative samples of ER patients, with special attention to both acute and chronic alcohol use, and to organisational and socio-cultural variables that may influence findings across studies. In-depth patient interviews may also be useful for a better understanding of drinking in the injury event and associated circumstances.

ABSTRACT: Diffusion tensor imaging (DTI) is a useful technique for non-invasively investigating the microstructural organization of white matter (WM), and the most consistent DTI finding regarding cocaine-related WM alterations is in the corpus callosum (CC). WM injury has also been observed in subjects with traumatic brain injury (TBI), including in the CC. We used DTI to test if the WM microstructure is relatively more impaired in cocaine-dependent subjects who had suffered a mild TBI (mTBI). Fractional anisotropy (FA), which reflects the degree of alignment of cellular structures within fiber tracts and their structural integrity, was compared across cocaine-dependent subjects with mTBI (COCTBI group, n=9), matched cocaine-dependent subjects without TBI (COC group, n=12), and matched healthy controls (CTL group, n=12). The COCTBI group had significantly lower FA in the genu, body, and splenium of CC, than the CTL group whenever the education was controlled or not. The COC group had significantly lower FA in the left and right anterior corona radiata than the CTL group only when the education was controlled. There was no significant difference in FA between the COC and COCTBI groups. Cocaine dependence (or mTBI) related WM impairments in the CC were not detectable in this small subject sample. The significant finding in the CC suggests that the concurrence of cocaine dependence and mTBI might result in more severe damage to the CC, which could even be detected in small sample size.

ABSTRACT: Objectives: Interpersonal communication about alcohol influences alcohol consumption, yet evidence is scarce about the content and valence of alcohol-related conversations and how these concepts predict alcohol consumption. Methods: By employing a correlational design among Dutch undergraduate students (N = 133), this study measured alcohol consumption predictors and conversational valence and occurrence regarding three topics (personal alcohol-related experiences; alcohol-related experiences of others; and alcohol-related media messages). Results: Results showed that people talk more often and more positively about (personal) alcohol-related experiences than about alcohol-related media messages. In contrast to media messages, whether and how positively people talk about alcohol-related experiences was related to several alcohol consumption determinants. Conclusions: Health promotion attempts should elicit negative conversations about alcohol-related experiences, thereby resulting in more healthy alcohol consumption predictors.

ABSTRACT: Background: Recent research using mobile phone interventions to address public health issues such as smoking, obesity, depression, and diabetes provides a basis for trialing a similar approach toward reducing the negative consequences of risky drinking. Objective: This feasibility study aims to recruit drinkers between 18–34 years to a website where they will design and enter their own personal messages (repeating or one-off) to be sent to their mobile phones when they are drinking to remind them of their pre-drinking safety intentions. Methods/Design: Participants in the treatment group will have access to the messaging function for 3 months and will be compared to a control group who will have 3 months access to a web chat site only. Data collection will occur at baseline, 3 months, and 6 months. The primary outcome is a change in unintended negative consequences from drinking at 3 months. Secondary outcomes include the acceptability of the intervention to this population, recruitment rate, participant retention, reduction in alcohol consumption, and the self-motivation discourse in participant messages. Discussion: Existing alcohol interventions in New Zealand attempt to reduce alcohol consumption in the population, but with little effect. This study aims to target unintended negative consequences resulting from drinking by empowering the drinkers themselves to deliver safety messages during the drinking session. If proven effective, this strategy could provide a cost-effective means of reducing the public health burden associated with risky drinking.
