Alcohol and drug use in Australian male sex workers: its relationship to the safety outcome of the sex encounter

This paper describes the self-reporting patterns of alcohol and drug consumption among male sex workers (MSWs) in three Australian cities during commercial sex encounters, and examines to what extent alcohol and drugs are used and whether this is related to the safe/unsafe outcome of the commercial sex encounter. One hundred and eighty-six MSWs from Brisbane, Sydney and Melbourne completed a diary following each commercial sex encounter over a two-week period. MSWs reported 2,087 commercial sex encounters during the study period. Alcohol or drug consumption was reported in 50.5% of the encounters.

The role of alcohol expectancy and drinking refusal self-efficacy beliefs in university student drinking

Aims: University student alcohol misuse is a considerable problem. Alcohol expectancy research has contributed significantly to our understanding of problem drinking in young adults. Most of this research has investigated positive expectancy alone. The current study utilized two measures of alcohol expectancy, the alcohol expectancy questionnaire (AEQ) and the drinking expectancy profile [consisting of the drinking expectancy questionnaire (DEQ) and the drinking refusal self-efficacy questionnaire] to predict severity of alcohol dependence, frequency of drinking, and the quantity of alcohol consumed per occasion. Methods: Measures of drinking behaviour and alcohol expectancy were completed by 174 undergraduate university students. Results: Positive alcohol expectancy factors accounted for significant variance in all three drinking indices, with the DEQ adding additional variance to AEQ scores on frequency and severity of alcohol dependence indices. Negative expectancy did not add incremental variance to the prediction of drinking behaviour in this sample. Drinking refusal self-efficacy and dependence beliefs added additional variance over positive and negative expectancies in the prediction of all three drinking parameters. Conclusions: Positive expectancy and drinking refusal self-efficacy were strongly related to university student drinking. The incorporation of expectancy as a means of informing prevention approaches in tertiary education shows promise.

University students' perceptions of the alcohol campaign : "Is Getting Pissed Getting Pathetic? (Just Ask Your Friends)"

The present study examined students' understanding and perceived effectiveness of a recent Australian alcohol campaign designed to increase students' awareness of excessive and harmful drinking. Six hundred and seventy one university students (51% females), who had seen the campaign posters, with the tagline "Is Getting Pissed Getting Pathetic? (Just Ask You Friends)", were asked to comment on the messages that the campaign was communicating and how informative, relevant, and effective they perceived the campaign. Many students were positive in their evaluations and described the messages as "truth and realistic", "clear and to the point", and that the campaign made them think about their own drinking. However, other views were more negative and indicative of psychological reactance. These included concerns that students "won't listen" or "don't care" about media campaigns, and that "they don't what to be told what to do". The findings highlight how media campaigns can help an audience contemplate behavioral change, however, they can also alienate students and promote counterproductive attitudes.

Pregnant women's alcohol consumption : the predictive utility of intention to drink and prepregnancy drinking behaviour

Objective: This study had two aims: (1) to examine pregnant women's alcohol consumption across time from prepregnancy until childbirth and (2) to explore whether prepregnancy drinking and intention to drink predict prenatal alcohol consumption while controlling for relevant demographic variables.

Methods: At 17–21 weeks, 248 pregnant women completed questions about demographics, intention to drink alcohol during the subsequent pregnancy, and retrospective measures of prepregnancy and early pregnancy consumption. After this time, calendars were sent fortnightly assessing daily alcohol consumption until birth.

Results: For women who drank both prepregnancy and postpregnancy confirmation, average fortnight alcohol consumption in the first weeks of pregnancy was lower than during prepregnancy, and consumption continued to decrease between gestational weeks 1 and 8, particularly following pregnancy confirmation, after which it remained relatively stable. When predicting whether women drank in late pregnancy, intention accounted for unique variance after controlling for income and prepregnancy drinking. For women who drank after pregnancy confirmation, prepregnancy drinking quantity significantly predicted intention to drink, which in turn predicted fortnight alcohol consumption in later pregnancy, after controlling for prepregnancy drinking and income.

Conclusions: Findings highlight the need to measure alcohol consumption at multiple time points across pregnancy, the need for educating and supporting women to reduce consumption when planning pregnancies, and the usefulness of intention to drink as a predictor of drinking during pregnancy.

Electrospun single-walled carbon nanotube/polyvinyl alcohol composite nanofibers : structure-property relationships

Polyvinyl alcohol (PVA) nanofibers and single-walled carbon nanotube (SWNT)/PVA composite nanofibers have been produced by electrospinning. An apparent increase in the PVA crystallinity with a concomitant change in its main crystalline phase and a reduction in the crystalline domain size were observed in the SWNT/PVA composite nanofibers, indicating the occurrence of a SWNT-induced nucleation crystallization of the PVA phase. Both the pure PVA and SWNT/PVA composite nanofibers were subjected to the following post-electrospinning treatments: (i) soaking in methanol to increase the PVA crystallinity, and (ii) cross-linking with glutaric dialdehyde to control the PVA morphology. Effects of the PVA morphology on the tensile properties of the resultant electrospun nanofibers were examined. Dynamic mechanical thermal analyses of both pure PVA and SWNT/PVA composite electrospun nanofibers indicated that SWNT–polymer interaction facilitated the formation of crystalline domains, which can be further enhanced by soaking the nanofiber in methanol and/or cross-linking the polymer with glutaric dialdehyde.

Evaluation of a community-based mental health drug and alcohol nurse in the care of people living with HIV/AIDS

There is a growing need for advanced practice mental health and drug and alcohol nursing roles in the care of people living with HIV/AIDS; however, limited publications address these domains. This study evaluated a community-based mental health drug and alcohol nurse role caring for people living with HIV/AIDS (Mental Health D&A Nurse) in a large not-for-profit district nursing organization providing care to people living with HIV/AIDS in an Australian city. Outcomes from a client assessment and 6–8-week follow-up by the Mental Health D&A Nurse are presented as captured by the Depression Anxiety Stress Scales (DASS 21), Alcohol, Smoking and Substance Involvement Screening Test (ASSIST), Health of the Nation Outcome Scales (HONOS) and WHOQoL BREF. Mean scores and caseness were analysed, and significant differences were found on the 'impairment' and 'social problems' subscales of the HONOS. Results of semi-structured interviews with clients describe effective and supportive mental health care and health-promoting education following visits by the Mental Health D&A Nurse. These positive findings support continuing implementation of the role within this community setting and indicate that even greater benefits will ensue as the role develops further. Findings are of interest to clinicians and policy makers seeking to implement similar roles in community-based HIV/AIDS care.

Cue reward salience predicts craving in response to alcohol cues

Many studies have shown that regular drinkers react to alcohol-related stimuli (i.e., cue reactivity) with a variety of appetitive responses, in particular, increased urge to drink. Recent research has focused on accounting for variability in responses to alcohol-related stimuli by examining drinking histories and personality. The aim of the current study was to extend this line of work by investigating the role of reinforcement expectancies (‘cue reward salience’) in alcohol cue reactivity research. In this study, ‘cue reward salience’ refers to the notion that appetitive responses will only ensue if the individual finds the stimulus to be equal to or more rewarding than initial expectations. Sixty-one regular drinkers completed a standard cue reactivity assessment whereby reactions (i.e., urge to drink and affect) to the sight, smell and taste of alcohol are measured and compared to a control condition. Results indicated significant increases in positive urge to drink but no changes in affect. Analyses revealed that drinking level and trait reward sensitivity were significant predictors of the urge to drink response. In addition, ‘cue reward salience’ accounted for significant additional variance in predicting urge to drink alcohol. Discussion focuses on the importance of measuring reinforcement expectancies when conducting cue reactivity studies.

Diacetone alcohol, a dispersant solvent, contributes to acute toxicity of a fipronil-based insecticide in a passerine bird

Fipronil, a phenyl pyrazole pesticide, is aerially applied in eastern Australia to control locust outbreaks, usually as “Adonis 3UL Insecticide^®” (BASF), an ultra low (UL) volume formulation containing 0.3% active pesticide. We tested the toxicities of technical-grade fipronil, the Adonis 3UL formulation and its components in zebra finch, a native bird at risk of exposure in locust control regions. We estimated oral-dose LD50 by the Up-and-Down method. Under laboratory conditions, we identified unexpectedly high toxicities due exclusively to diacetone alcohol (DAA), a solvent making up 12.5% of the Adonis 3UL formulation. In contrast, finches were asymptomatic when exposed to 0.3% technical grade fipronil dissolved in a minimum amount of acetone. Depending upon the behaviour and persistence of DAA under field conditions, this formulation of Adonis 3UL may pose a far greater threat to the health of small birds and possibly other vertebrates than expected for fipronil alone.

The burden of alcohol-related ill health in the United Kingdom

Background Although moderate alcohol consumption has been shown to confer a protective effect for specific diseases, current societal patterns of alcohol use impose a huge health and economic burden on modern society. This study presents a method for estimating the health and economic burden of alcohol consumption to the UK National Health Service (NHS).

Methods Previous estimates of NHS costs attributable to alcohol consumption were identified by systematic literature review. The mortality and morbidity due to alcohol consumption was calculated using information from the World Health Organization Global Burden of Disease Project and routinely collected mortality data. Direct health-care costs were derived using information on population attributable fractions for conditions related to alcohol consumption and NHS cost data.

Results We estimate that alcohol consumption was responsible for 31 000 deaths in the UK in 2005 and that alcohol consumption cost the UK NHS £3.0 billion in 2005–06. Alcohol consumption was responsible for 10% of all disability adjusted life years in 2002 (male: 15%; female: 4%) in the UK.

Conclusions Alcohol consumption is a considerable public health burden in the UK. The comparison of the health and economic burden of various lifestyle factors is essential in prioritizing and resourcing public health action.
