Alcohol use is a major cause of disability and death worldwide. To improve prevention and treatment addressing unhealthy alcohol use, experts recommend that alcohol-related care be integrated into primary care (PC). However, few healthcare systems do so. To address this gap, implementation researchers and clinical leaders at Kaiser Permanente Washington partnered to design a high-quality Program of Sustained Patient-centered Alcohol-related Care (SPARC). Here, we describe the SPARC pilot implementation, evaluate its effectiveness within three large pilot sites, and describe the qualitative findings on barriers and facilitators. Across the three sites (N = 74,225 PC patients), alcohol screening increased from 8.9% of patients pre-implementation to 62% post-implementation (p < 0.0001), with a corresponding increase in assessment for alcohol use disorders (AUD) from 1.2 to 75 patients per 10,000 seen (p < 0.0001). Increases were sustained over a year later, with screening at 84.5% and an assessment rate of 81 patients per 10,000 seen across all sites. In addition, there was a 50% increase in the number of new AUD diagnoses (p = 0.0002), and a non-statistically significant 54% increase in treatment within 14 days of new diagnoses (p = 0.083). The pilot informed an ongoing stepped-wedge trial in the remaining 22 PC sites. PMID:28885557

Objective: This study investigated the effectiveness of three single-session interventions with high-risk mandated students while considering the influence of motivational interviewing (MI) microskills. Method: This randomized, controlled pilot trial evaluated single-session interventions: Alcohol Skills Training Program (ASTP), Brief Alcohol Screening and Intervention for College Students (BASICS) feedback sessions, and treatment-as-usual Alcohol Diversion Program (ADP) educational groups. Participants were 61 full-time undergraduates at a southern U.S. campus sanctioned to a clinical program following violation of an on-campus alcohol policy (Mage = 19.16 years; 42.6% female). Results: Results revealed a significant effect of time for reductions in estimated blood alcohol concentration (eBAC) and number of weekly drinks but not in alcohol-related consequences. Although ASTP and BASICS participants reported significant decreases in eBAC over time, ADP participant levels did not change (with no intervention effects on quantity or consequences). MI microskills were not related to outcomes. Conclusions: Results from this study suggest equivalent behavioral impacts for the MI-based interventions, although individual differences in outcome trajectories suggest that research is needed to further customize mandated interventions. Given the overall decrease in eBAC following the sanction, the lack of reduction in the ADP condition warrants caution when using education-only interventions. PMID:25486391

The upsurge in alcohol use that often occurs during the first year of college has been convincingly linked to a number of negative psychosocial consequences and may negatively affect brain development. In this longitudinal functional magnetic resonance imaging (fMRI) pilot study, we examined changes in neural responses to alcohol cues across the first year of college in a normative sample of late adolescents. Participants (N=11) were scanned three times across their first year of college (summer, first semester, second semester), while completing a go/no-go task in which images of alcoholic and non-alcoholic beverages were the response cues. A state-of-the-art effective connectivity mapping technique was used to capture spatiotemporal relations among brain regions of interest (ROIs) at the level of the group and the individual. Effective connections among ROIs implicated in cognitive control were greatest at the second assessment (when negative consequences of alcohol use increased), and effective connections among ROIs implicated in emotion processing were lower (and response times were slower) when participants were instructed to respond to alcohol cues compared to non-alcohol cues. These preliminary findings demonstrate the value of a prospective effective connectivity approach for understanding adolescent changes in alcohol-related neural processes.

Two-thirds of those with HIV worldwide live in sub-Saharan Africa. Alcohol use is associated with the HIV epidemic through risky sex and suboptimal ARV adherence. In western Kenya, hazardous drinking was reported by HIV (53%) and general medicine (68%) outpatients. Cognitive behavioral treatment (CBT) has demonstrated strong efficacy to reduce alcohol use. This article reports on a systematic cultural adaptation and pilot feasibility study of group paraprofessional-delivered CBT to reduce alcohol use among HIV-infected outpatients in Eldoret, Kenya. Following adaptation and counselor training, five pilot groups were run (n = 27). Overall attendance was 77%. Percent days abstinent from alcohol (PDA) before session 1 was 52-100% (women) and 21-36% (men), and by session 6 was 96-100% (women) and 89-100% (men). PDA effect sizes (Cohen's d) between first and last CBT session were 2.32 (women) and 2.64 (men). Participants reported treatment satisfaction. Results indicate feasibility, acceptability and preliminary efficacy for CBT in Kenya.

Although we know a great deal about the percentage of youth who drink alcohol, we know very little about the specific brands they choose to drink. This information gap needs to be addressed if public health officials are to develop more effective interventions. Unfortunately, there are no national youth surveys that collect data on alcohol brand consumption. In this paper, we describe the development and pilot testing of what we believe to be the first comprehensive, Internet-based youth survey of brand-specific alcohol use. We used online advertising in 3 U.S. cities to recruit a convenience sample of 241 respondents, ages 16 to 18 years. We used Craigslist, a network of online communities that features local classified advertisements, to recruit the sample. We used SurveyGizmo, an online software program for designing Internet surveys, collecting data, and performing basic analysis, to survey these respondents about their brand-specific alcohol consumption patterns. The survey instrument assessed each respondent's 30-day drinking history, including the frequency of consumption for each alcohol brand. Using Internet survey technology, we were able to collect information on 366 brands and still have respondents complete the instrument quickly and easily. The total number of brands consumed in the past 30 days ranged from 1 to 18, with a median of 4 brands. The top 5 brands consumed were beer brands, as were eleven of the top 15 brands. The remaining 4 brands in the top 15 included 3 brands of flavored alcoholic beverages and 1 brand of mixed drink. Among the top 15 alcohol brands consumed during heavy drinking episodes were 8 brands of beer, 4 brands of flavored alcoholic beverages, 2 brands of wine, and 1 brand of mixed drink. This pilot study helps establish the feasibility of including brand-specific questions on federal or other national youth alcohol surveys. Copyright © 2011 by the Research Society on Alcoholism.

Excessive alcohol consumption compromises health and increases risk of mortality. Advertisements for alcohol in city environments have been shown to influence consumption. The aim of this pilot study was to estimate the prevalence of alcohol advertisements displayed on LinkNYC kiosks, a new communication channel that provides outdoor Wi-Fi access and advertising on streets within urban environments. Direct observations were conducted to document advertisements on a 20% random sample of the 500 LinkNYC kiosks in Manhattan, NYC. From May to September of 2017, each of the 100 selected kiosks was observed for a 10-min period to document advertisements for alcohol. In addition, differences in prevalence of alcohol advertisements were examined by the location of the kiosk based on NYC zip codes' median annual income. Of the 2025 advertisements observed, 5.09% (N = 103) were for an alcohol product (including duplicates). Such advertisements were observed on 17% of the kiosks. No health warnings or age warnings were presented in any of the alcohol advertisements. Compared with kiosks located in zip codes with lower median annual income, significantly more alcohol advertisements were displayed in zip codes with higher median annual income. This is the first study to estimate the prevalence of alcohol advertising on the LinkNYC Wi-Fi and telecommunication system, now ubiquitous on Manhattan's sidewalks. This study adds to the current literature that suggests New York City residents could benefit from health-promoting versus health-compromising advertising. The findings also highlight the potential of LinkNYC kiosk marketing to undermine health-related social marketing efforts by City government and other organizations.

Integrating alcohol response feedback in a brief intervention for young adult heavy drinkers who smoke: A pilot study.

More effective approaches are needed to enhance drinking and other health behavior (e.g., smoking) outcomes of alcohol brief intervention (BI). Young adult heavy drinkers often engage in other health risk behaviors and show sensitivity to alcohol's stimulating and rewarding effects, which predicts future alcohol-related problems. However, standard alcohol BIs do not address these issues. The current pilot study tested the utility of including feedback on alcohol response phenotype to improve BI outcomes among young adult heavy drinkers who smoke (HDS). Thirty-three young adult (M±SD age=23.8±2.1 years) HDS (8.7±4.3 binge episodes/month; 23.6±6.3 smoking days/month) were randomly assigned to standard alcohol BI (BI-S; n=11), standard alcohol BI with personalized alcohol response feedback (BI-ARF; n=10), or a health behavior attention control BI (AC; n=11). Alcohol responses (stimulation, sedation, reward, and smoking urge) for the BI-ARF were recorded during a separate alcohol challenge session (.8g/kg). Outcomes were past-month drinking and smoking behavior assessed at 1- and 6-months post-intervention. At 6-month follow-up, the BI-ARF produced significant reductions in binge drinking, alcohol-smoking co-use, drinking quantity and frequency, and smoking frequency, but not maximum drinks per occasion, relative to baseline. Overall, the BI-ARF produced larger reductions in drinking/smoking behaviors at follow-up than did the BI-S or AC. Including personalized feedback on alcohol response phenotype may improve BI outcomes for young adult HDS. Additional research is warranted to enhance and refine this approach in a broader sample.

The U.S. Preventive Services Task Force recommends that clinicians adopt universal alcohol screening and brief intervention as a routine preventive service for adults, and efforts are underway to support its widespread dissemination. The likelihood that healthcare systems will sustain this change, once implemented, is under-reported in the literature. This article identifies factors that were important to postimplementation sustainability of an evidence-based practice change to address alcohol misuse that was piloted within three diverse primary care organizations. The Centers for Disease Control and Prevention funded three academic teams to pilot and evaluate implementation of alcohol screening and brief intervention within multiclinic healthcare systems in their respective regions. Following the completion of the pilots, teams used the Program Sustainability Assessment Tool to retrospectively describe and compare differences across eight sustainability domains, identify strengths and potential threats to sustainability, and make recommendations for improvement. Health systems varied across all domains, with greatest differences noted for Program Evaluation, Strategic Planning, and Funding Stability. Lack of funding to sustain practice change, or data monitoring to promote fit and fidelity, was an indication of diminished Organizational Capacity in systems that discontinued the service after the pilot. Early assessment of sustainability factors may identify potential threats that could be addressed prior to, or during implementation to enhance Organizational Capacity. Although this study provides a retrospective assessment conducted by external academic teams, it identifies factors that may be relevant for translating evidence-based behavioral interventions in a way that assures that they are sustained within healthcare systems. © The Society of Behavioral Medicine 2018.

The aim of this pilot study was to evaluate whether sleep was improved by a 1-day sleep education program in an occupational setting and whether stopping alcohol intake at bedtime might influence sleep. Subjects were 40 high school employees. The sleep education program lasted 4.5 hours and consisted of sleep science information, and sleep hygiene education including the risk of sleep related breathing disorder resulting from alcohol intake. Sleep conditions were evaluated by self-administered questionnaires at baseline and approximately 1 month later. The mean the Epworth Sleepiness Scale (ESS) score was significantly decreased by 1.2 points (P = 0.04), while the mean sleep duration was significantly decreased by 10 minutes (P = 0.02). Shortened sleep duration coincided with a decrease in sleepiness. This may indicate an improvement in sleep quality. The percentage of habitual alcohol intake at bedtime was significantly decreased (from 38.5% (15/39) to 20.5% (8/39), P = 0.04). Subjects who stopped alcohol intake at bedtime (n = 8) received the most benefit, with decreased scores of ESS and Insomnia Severity Index (ISI), although the reductions were not significant. This education program offers the possibility of improving sleep conditions among the general population, especially in those who cease habitual alcohol intake at bedtime. Further larger, randomized, controlled studies are warranted.

An intrinsic drawback with the use of a computer-assisted telephone interview (CATI) survey methodology is that people who live in households without a connected landline telephone are excluded from the survey sample. This paper presents a pilot of the feasibility of a computer-assisted cell-phone interview (CACI) methodology designed to survey people living in households without a telephone about alcohol use and be compatible with a larger telephone based alcohol sample. The CACI method was found to be an efficient and cost competitive method to reach non-telephone households. Telephone ownership was found to make a difference to the typical occasion amount of alcohol consumed, with respondents from households without telephones drinking significantly more than those with telephones even when consumption levels were controlled for socio-economic status. Although high levels of telephone ownership in the general population mean these differences may not have any impact on population alcohol measures they may be important in sub-populations where telephone ownership is lower.

2016-10-01

We sought to examine social anxiety as a risk factor for alcohol-related sexual victimization among college women. Women (Time 1: n = 574; Time 2: n = 88) who reported consuming alcohol at least once during the assessment timeframe participated. Social anxiety, alcohol use, alcohol-related consequences, and sexual victimization were assessed twice, approximately two months apart. Logistic regressions were used to examine social anxiety as a risk factor for alcohol-related sexual victimization at both time points. Longitudinally, women high in social anxiety were approximately three times more likely to endorse unwanted alcohol-related sexual experiences compared to women with low to moderate social anxiety. This study suggests social anxiety, a modifiable construct, increases risk for alcohol-related sexual victimization among college women. Implications for clinicians and risk-reduction program developers are discussed. Published by Elsevier Ltd.

The study aimed to evaluate the efficacy of acetyl-l-carnitine (ALC), at different doses, in relapse prevention and craving in anhedonic detoxified alcohol-dependent subjects. Randomized, double-blind, placebo-controlled, pilot study in 64 alcohol-dependent anhedonic patients: 23 received ALC at a dose of 3 g/day, 21 received ALC at a dosage of 1 g/day and 20 were given placebo. Intensity of alcohol craving was evaluated by Visual Analogue Scale. Subjects were evaluated at the beginning of treatment and after 10, 30, 60 and 90 days. Survival analysis showed that patients treated with ALC remained completely abstinent for longer than those treated with placebo (Z = -2.27; P < 0.05). From the 10th day onwards, a greater reduction of craving was observed in the ALC 1 g group than with placebo (P = 0.035). The two groups did not differ in the percentage of subjects remaining abstinent for the entire study period or the number of subjects who relapsed (defined as five or more standard drinks (four for women) on a single occasion or drinking on five or more days in 1 week). The results of this study suggest that ALC can reduce craving and the time to first drink. ALC use was safe. Further studies are needed to clarify to confirm, over longer periods, these short-term outcome benefits.

Alcohol misuse is a major cause of premature mortality and ill health. Although there is a high prevalence of alcohol problems among patients presenting to general hospital, many of these people are not help seekers and do not engage in specialist treatment. Hospital admission is an opportunity to steer people towards specialist treatment, which can reduce health-care utilization and costs to the public sector and produce substantial individual health and social benefits. Alcohol misuse is associated with other lifestyle problems, which are amenable to intervention. It has been suggested that the development of a healthy or balanced lifestyle is potentially beneficial for reducing or abstaining from alcohol use, and relapse prevention. The aim of the study is to test whether or not the offer of a choice of health-related lifestyle interventions is more acceptable, and therefore able to engage more problem drinkers in treatment, than an alcohol-focused intervention. This is a pragmatic, randomized, controlled, open pilot study in a UK general hospital setting with concurrent economic evaluation and a qualitative component. Potential participants are those admitted to hospital with a diagnosis likely to be responsive to addiction interventions who score equal to or more than 16 on the Alcohol Use Disorders Identification Test (AUDIT). The main purpose of this pilot study is to evaluate the acceptability of two sorts of interventions (healthy living related versus alcohol focused) to the participants and to assess the components and processes of the design. Qualitative research will be undertaken to explore acceptability and the impact of the approach, assessment, recruitment and intervention on trial participants and non-participants. The effectiveness of the two treatments will be compared at 6 months using AUDIT scores as the primary outcome measure. There will be additional economic, qualitative and secondary outcome measurements. Development of the study was a collaboration between academics, commissioners and clinicians in general hospital and addiction services, made possible by the Collaboration in Leadership in Applied Health Research and Care (CLAHRC) program of research. CLAHRC was a necessary vehicle for overcoming the barriers to answering an important NHS question--how better to engage problem drinkers in a hospital setting. ISRCTN47728072.

Effects of Logo-autobiography Program on Meaning in Life and Mental Health in the Wives of Alcoholics.

Cho, Sunhee

2008-06-01

This study aimed to identify the effectiveness of a newly developed group therapy, called the logo-autobiography program, in improving meaning in life and mental health in the wives of alcoholics. The program was developed in four steps: literature review, pilot program development, pilot study and detailed program structuring. The pilot program was developed by combining a modified guided autobiography program with logotherapy. A non-randomized controlled trial was conducted with a pre- and post-test design. The instruments chosen for the study were the Purpose in Life (PIL) test and the Symptom Checklist-90-Revision (SCL-90-R) to measure the meaning in life and mental health. Data were collected between November 2006 and March 2007 from 19 subjects in the experimental group and 21 subjects in the control group, who were all wives of alcoholics from four South Korean cities. The score for meaning in life was significantly higher in the experimental group than in the control group (p = .047). Also, the scores for somatization (p = .001), interpersonal sensitivity (p = .008), depression (p = .003), hostility (p = .002) and global severity index (p = .001) were significantly lower in the experimental group than in the control group. This study indicated that the logo-autobiography program enhanced both meaning in life and mental health in alcoholics' wives, which suggests that the program would be very beneficial to this population. Furthermore, it might be suitable for improving mental health in families and communities that suffer from psychological trauma and meaninglessness.

A pilot study investigating of the nature of point-of-sale alcohol promotions in bottle shops in a large Australian regional city.

PubMed

Jones, Sandra C; Lynch, Melissa

2007-08-01

The promotion of alcohol by retailers and media can contribute to a culture of excessive alcohol consumption, but the effect of non-advertising alcohol promotions has largely been neglected. This study sought to gather initial data on this important area. An observational study of alcohol point-of-sale promotions in the Wollongong CBD area, conducted in July-August 2005. We identified 17 different promotions in three categories: gift with purchase; competitions; and buy some, get some free. Given previous research demonstrating the relationship between increased alcohol consumption and both ownership of alcohol-related merchandise and reduced per unit price, it appears that point-of-sale promotions may have the potential to further increase alcohol consumption among young people. Only when the extent and impact of such promotions is demonstrated will we be in a position to effectively advocate for appropriate regulations to ensure young people are not exposed to marketing strategies that further increase their exposure to alcohol-related harms.

This study assessed personality disorders (PDs) in 158 alcohol-dependent outpatients (62 manifesting cocaine abuse and 96 without cocaine abuse) with the International Personality Disorders Examination interview between 2003 and 2006. Thirty-nine alcohol-dependent/cocaine abusers (62.9% of this group) and 51 only alcohol-dependent patients (53.1% of this group) manifested at least one PD. There were no statistically significant differences between groups in the overall prevalence rate of PDs. The most prevalent PDs, among the alcohol-dependent/cocaine abusers, were antisocial (21%), narcissistic (14.5%), and borderline (11.3%) PDs. The most frequently diagnosed PDs among the only alcohol-dependent patients were obsessive-compulsive (20.8%), paranoid (10.4%), and dependent (9.4%) PDs. There were significant differences between the groups. The study limitations are discussed.

There is a higher prevalence of alcohol use and severe alcohol dependence among homeless populations. The combination of alcohol use and lack of housing contributes to increased vulnerability to the harms of substance use including stigma, injury, illness, and death. Managed alcohol programs (MAPs) administer prescribed doses of alcohol at regular intervals to people with severe and chronic alcohol dependence and homelessness. As a pilot for a larger national study of MAPs, we conducted an in-depth evaluation of one program in Ontario, Canada. In this paper, we report on housing and quality of life outcomes and experiences of the MAP participants and staff. We conducted a pilot study using mixed methods. The sample consisted of 38 people enrolled in or eligible for entry into a MAP who completed a structured quantitative survey that included measures related to their housing and quality of life. All of the participants self-identified as Indigenous. In addition, we conducted 11 in-depth qualitative interviews with seven MAP residents and four program staff and analyzed the interviews using constant comparative analysis. The qualitative analysis was informed by Rhodes' risk environment framework. When compared to controls, MAP participants were more likely to retain their housing and experienced increased safety and improved quality of life compared to life on the streets, in jails, shelters, or hospitals. They described the MAP as a safe place characterized by caring, respect, trust and a nonjudgmental approach with a sense of family and home as well as opportunities to reconnect with family members. The MAP was, as described by participants, a safer environment and a home with feelings of family and a sense of community that countered stigma, loss, and dislocation with potential for healing and recovery. The MAP environment characterized by caring, respect, trust, a sense of home, "feeling like family", and the opportunities for family and cultural reconnections is consistent with First Nations principles for healing and recovery and principles of harm reduction.

Alcohol media literacy programs in the United States have increased students' media literacy skills and lowered pre-drinking behaviour. In Australia, no such programs have yet been implemented or evaluated. This pilot study aimed to examine the feasibility and potential impact of an alcohol media literacy program for Australian upper-primary school children. Thirty-seven Year 5 and 6 students (aged 10-12) from one school in the Sydney region participated in 10 one-hour media lessons. Teacher interviews, student exit slips, teacher observations and a researcher reflective journal were analysed to examine the implementation process, while a pre- and post-questionnaire was analysed to measure outcome. Key factors in implementation were the importance of school context; attainment of English and PDHPE learning outcomes to differing extents; program's useability provided flexibility; perceived complexity and achievability of the lessons and program's engagement and relevance for the students. The program significantly increased media literacy skills and understanding of persuasive intent; decreased interest in alcohol branded merchandise; and lowered perception of drinking norms. An Australian alcohol media literacy program for upper-primary school children appears feasible, and has potential to lead to measurable outcomes. © 2015 Public Health Association of Australia.

A large proportion of individuals with alcohol problems do not seek psychological treatment, but access to such treatment could potentially be increased by delivering it over the Internet. Cognitive behavior therapy (CBT) is widely recognized as one of the psychological treatments for alcohol problems for which evidence is most robust. This study evaluated a new, therapist-guided internet-based CBT program (entitled ePlus) for individuals with alcohol use disorders. Participants in the study (n = 13) were recruited through an alcohol self-help web site ( www.alkoholhjalpen.se ) and, after initial internet screening, were diagnostically assessed by telephone. Eligible participants were offered access to the therapist-guided 12-week program. The main outcomes were treatment usage data (module completion, treatment satisfaction) as well as glasses of alcohol consumed the preceding week, measured with the self-rated Timeline Followback (TLFB). Participant data were collected at screening (T0), immediately pre-treatment (T1), post-treatment (T2) and 3 months post-treatment (T3). Most participants were active throughout the treatment and found it highly acceptable. Significant reductions in alcohol consumption with a large within-group effect size were found at the three-month follow-up. Secondary outcome measures of craving and self-efficacy, as well as depression and quality of life, also showed significant improvements with moderate to large within-group effect sizes. Therapist-guided internet-based CBT may be a feasible and effective alternative for people with alcohol use disorders. In view of the high acceptability and the large within-group effect sizes found in this small pilot, a randomized controlled trial investigating treatment efficacy is warranted.

Objectives The abuse of alcohol is a major public health problem, and the diagnosis and care of patients with alcohol abuse and dependence is hindered by the lack of tests that can detect dangerous levels of drinking or relapse during therapy. Gastroenterologists and other healthcare providers find it very challenging to obtain an accurate alcohol drinking history. We hypothesized that the effects of ethanol on numerous systems may well be reflected in changes in quantity or qualities of constituent or novel plasma proteins or protein fragments. Organ/tissue-specific proteins may be released into the blood stream when cells are injured by alcohol, or when systemic changes are induced by alcohol, and such proteins would be detected using a proteomic approach. The objective of this pilot study was to determine if there are plasma proteome profiles that correlate with heavy alcohol use. Methods Paired serum samples, before and after intensive alcohol treatment, were obtained from subjects who attended an outpatient alcohol treatment program. Serum proteomic profiles using MALDI –OTOF Mass Spectrometry were compared between pre- and post treatment samples. Results Of 16 subjects who enrolled in the study, 8 were females. The mean age of the study subjects was 49 yrs. The baseline laboratory data showed elevated AST (54 ± 37 IU/L), ALT (37 ± 19 IU/L), and MCV (99 ± 5 fl). Self-reported pre-treatment drinking levels for these subjects averaged 17 ± 7drinks/day and 103 ± 37 drinks/week. Mass spectrometry analyses showed a novel 5.9 kDa protein, a fragment of alpha fibrinogen, isoform 1, that might be might be a new novel marker for abusive alcohol drinking. Conclusions We have shown in this pilot study that several potential protein markers have appeared in mass spectral profiles and that they may be useful clinically to determine the status of alcohol drinking by MALDI –OTOF mass spectrometry, especially a fragment of alpha fibrinogen, isoform 1. However, a large-scale study is needed to confirm and validate our current results. PMID:19672327

[The effects of small amounts of alcohol on in-flight activity].

PubMed

Dionisi, A

1981-10-06

Alcohol metabolism is described prior to an account of its effect on vigilance. The psychological and psychosomatic influence of alcohol is also illustrated in the light of experimental data indicating how it alters the response to stimuli. Alterations in various parameters following the administration of significantly small doses of alcohol were studied. Reaction time decreased, then increased, followed by a further decrease after about 1 1/2 hr. Even 1/8th litre depresses receptiveness of the reticular substance, and leads to lengthening of reaction times due to diminished ability to concentrate attention on a given task. CNS depression is also in proportion to the complexity of the performance required. This is particularly and dangerous in pilots, whose tasks are extremely precise and require close attention. Functional alterations induced by alcohol during flight may be numerous, due to disturbances connected with the specific conditions created by flying, and apparatuses whose physiological functions are susceptible to disturbance by flying itself. Alcohol, itself a harmful influence on piloting an aircraft, deteriorates these functions and conditions. Toxic substances present during flying and their potentiation by alcohol are considered. The effects of alcohol, added to these specific pathogenetic toxic effects, quickly and readily lead to a fall in overall psychophysical efficiency, and prejudice flight safety. the reason why a decrease in the limit intake doses to less than 2 cc/kg, equivalent to a blood value of 0.5 g 0/00, to ensure safe control of the plane, is desirable is explained.

2018-01-01

Research on the clinical applications of psychedelic-assisted psychotherapy has demonstrated promising early results for treatment of alcohol dependence. Detailed description of the content and methods of psychedelic-assisted psychotherapy, as it is conducted in clinical settings, is scarce. Methods: An open-label pilot (proof-of-concept) study of psilocybin-assisted treatment of alcohol dependence (NCT01534494) was conducted to generate data for a phase 2 RCT (NCT02061293) of a similar treatment in a larger population. The present paper presents a qualitative content analysis of the 17 debriefing sessions conducted in the pilot study, which occurred the day after corresponding psilocybin medication sessions. Results: Participants articulated a series of key phenomena related to change in drinking outcomes and acute subjective effects of psilocybin. Discussion: The data illuminate change processes in patients' own words during clinical sessions, shedding light on potential therapeutic mechanisms of change and how participants express effects of psilocybin. This study is unique in analyzing actual clinical sessions, as opposed to interviews of patients conducted separately from treatment. PMID:29515449

A computerized task was used in two studies to examine the influence of stimulants, sedatives, and fatigue on single-target and divided-attention responses in different parts of the visual field. The drug effects were evaluated over time with repeated behavioral and subjective measures against ascending and descending drug levels. In the first study, 18 fully rested participants received placebo, alprazolam (0.5 mg), and dextroamphetamine (10 mg). Alprazolam impairs performance, whereas dextroamphetamine induces enhancement and tunnel vision. Study 2 exposed 32 participants to fatigue and no fatigue with a repeated-measures crossover design. Four independent groups subsequently received placebo, dextroamphetamine (10 mg), caffeine (250 mg), or alcohol (.07%). Under fatigue, stimulants have no performance-enhancing effects, whereas impairment from alcohol is severe. Under no fatigue, alcohol has a modest effect, caffeine has no effect, and dextroamphetamine significantly enhances divided-attention performance coincident with tunnel vision. Participants rate all drug effects more stimulating and less sedating while fatigued. Implications for transportation safety are discussed. Actual or potential applications of this research include driver and pilot training.

2015-01-01

Objective To date no research has evaluated the efficacy of a stand-alone, smartphone-based intervention for individuals with an alcohol use disorder. The current pilot study evaluated the short-term outcomes of a smartphone-based intervention for alcohol use disorders compared with an internet-based brief motivational intervention plus bibliotherapy. Method Adults (18 to 45 years old) with an alcohol use disorder received either the Location-Based Monitoring and Intervention for Alcohol Use Disorders (LBMI-A; n = 28), a smartphone-based intervention, or the online Drinker’s Check-up plus bibliotherapy (DCU+bib; n = 26). These groups were compared using the Timeline Followback interview for percent days abstinent (PDA), percent heavy drinking days (PHDD), and drinks per week (DPW) from baseline to six weeks after the introduction of the interventions. Results Multilevel models revealed that the LBMI-A resulted in a significant increase in PDA over the course of the study, while the DCU+bib did not. Effect sizes for change from baseline for PDA suggest that the DCU+bib resulted in moderate a decrease, while the LBMI-A resulted in a large increase in PDA. Both interventions resulted in significant decreases in PHDD and DPW. The LBMI-A produced larger reductions in the first three to four weeks after the intervention was introduced than the DCU+bib. On weeks with greater LBMI-A usage, participants reported less DPW and PHDD. Conclusions Both interventions resulted in significant decreases in alcohol use over the 6-week trial, which is promising for stand-alone technology-based intervention systems aimed at individuals with an alcohol use disorder.

2013-09-03

We report results of a pilot study designed to test a novel smoking cessation intervention, Mindfulness Training for Smokers (MTS), in smokers age 18-29 years with regular episodes of binge drinking. Mindfulness is a cognitive skill of applying close moment-to-moment attention to experience with a mental posture of acceptance and non-reactivity. The MTS intervention consisted of six weekly classes that provided instruction on how to use mindfulness to manage known precursors of smoking relapse including smoking triggers, strong emotions, stressful situations, addictive thoughts, urges, and withdrawal symptoms. The MTS intervention was compared to Interactive Learning for Smokers (ILS), a time/intensity matched control group using daily non-directed walking instead of mindfulness meditation. Recruitment was conducted primarily at local technical colleges. Primary outcome measures included biochemically-confirmed smoking abstinence and reduction in alcohol use at the end of treatment (2-weeks post-quit attempt). The sample (N = 55) was 70.9% male, with a mean age of 21.9 years, and a mean of 11.76 alcoholic drinks consumed per week. Intent-to-treat analysis showed biochemically-confirmed 7-day point prevalence abstinence rates at 2-weeks post-quit for MTS = 20.0% and ILS = 4.0%, p = .08. Secondary analysis showed number of drinks per week in the first 2-weeks post-quit correlated with smoking relapse at 2-weeks post-quit (p < .01). This pilot study demonstrated that Mindfulness Training for Smokers shows promise for smoking cessation and alcohol use reduction in treating young adult smokers with alcohol abuse. Results suggest the need for a study with larger sample size and methods that reduce attrition. ClnicalTrial.gov, NCT01679236.

Reduction factors (RFs) for bacterial counts on examiners' hands were compared when performing a standardized equine physical examination, followed by the use of one of 3 hand-hygiene protocols (washing with soap, ethanol gel application, and chlorohexidine-ethanol application). The mean RFs were 1.29 log10 and 1.44 log10 at 2 study sites for the alcohol-gel (62% ethyl alcohol active ingredient) protocols and 1.47 log10 and 1.94 log10 at 2 study sites for the chlorhexidine-alcohol (61% ethyl alcohol plus 1% chlorhexidine active ingredients) protocols, respectively. The RFs were significantly different (P < 0.0001) between the hand-washing group and the other 2 treatment groups (the alcohol-gel and the chlorhexidine-alcohol lotion). The use of alcohol-based gels or chlorhexidine-alcohol hand hygiene protocols must still be proven effective in equine practice settings, but in this study, these protocols were equivalent or superior to hand washing for reduction in bacterial load on the hands of people after they perform routine physical examinations.

Alcohol expectancies and social self-efficacy as mediators of differential intervention outcomes for college hazardous drinkers with social anxiety.

PubMed

Black, Jessica J; Tran, Giao Q; Goldsmith, Abigail A; Thompson, Rachel D; Smith, Joshua P; Welge, Jeffrey A

2012-03-01

The current pilot study examined the roles of two cognitive factors - positive alcohol expectancies of social anxiety reduction and drink refusal self-efficacy relevant to social situations - in mediating greater reduction in alcohol behaviors by the Brief Intervention for Socially Anxious Drinkers (BISAD; n=21) compared to an alcohol psychoeducation (n=20) in a sample of college hazardous drinkers with social anxiety. Mediation analysis results indicated that decreased positive alcohol expectancies and increased drink refusal self-efficacy relevant to social situations accounted for an average of 67% of the variance in treatment outcomes as measured by total quantity of alcohol consumption, heavy drinking days and problems related to alcohol use in the past month. Study results may enhance the understanding of cognitive factors' role in alcohol treatment outcomes, which could in turn improve the efficacy of interventions aimed to reduce hazardous drinking and comorbid social anxiety.

Pilots' attitudes toward alcohol use and flying.

PubMed

Ross, L E; Ross, S M

1988-10-01

Questionnaires were sent to a national sample of licensed pilots. Respondents reported their flying experience and their drinking behavior. They also indicated the number of drinks that they believed could be safely consumed 3 hours (h) before flying or driving, and estimated the numbers of hours a person should wait, after drinking, before attempting to fly or drive. Similar questions were included regarding marijuana use. Respondents were much more conservative in their attitudes toward the use of alcohol prior to flying than prior to driving. This relationship held both for the number of drinks judged safe 3 h prior to flying or driving and for estimates of the waiting interval that would be appropriate following alcohol consumption. In addition, attitudes toward alcohol use were related to respondents' own drinking behavior, with moderate and heavy drinkers more tolerant of alcohol use in flying and driving situations than abstainers.

2011-01-01

People are exposed to many references to alcohol, which might influence their consumption of alcohol directly. In a field experiment, we tested whether textual references to alcohol in music played in bars lead to higher revenues of alcoholic beverages. We created two databases: one contained songs referring to alcohol, the parallel database contained songs with matching artists, tempo, and energetic content, but no references to alcohol. Customers of three bars were exposed to either music textually referring to alcohol or to the control condition, resulting in 23 evenings in both conditions. Bartenders were instructed to play songs with references to alcohol (or not) during a period of 2 hours each of the evenings of interest. They were not blind to the experimental condition. The results showed that customers who were exposed to music with textual references to alcohol spent significantly more on alcoholic drinks compared to customers in the control condition. This pilot study provides preliminary evidence that alcohol-related lyrics directly affect alcohol consumption in public drinking places. Since our study is one of the first testing direct effects of music lyrics on consumption, our small-scale, preliminary study needs replication before firm conclusions can be drawn.

Rationale There is presently no approved single treatment for dual alcohol and nicotine dependencies. Objective This pilot study investigated baclofen effects in alcoholic smokers. Methods This was a preliminary double-blind placebo-controlled randomized clinical study with 30 alcoholic smokers randomized to baclofen at 80 mg/day or placebo. A subgroup (n=18) participated in an alcohol cue-reactivity experiment. Results Baclofen, compared with placebo, significantly decreased the percent days of abstinence from alcohol-tobacco co-use (p=0.004). Alcohol dependence severity moderated baclofen effects, with the higher severity group having the greater baclofen response (p<0.001). Although the percent days of alcohol-tobacco co-use declined in both groups, this decline was greater after placebo than baclofen (p<0.001). Secondary analyses on alcohol or tobacco use alone suggested that the increase in percent days of co-abstinence was driven by the medication differences on heavy drinking days and on percent days smoking. In the cue-reactivity substudy, baclofen slightly decreased alcohol urge (p=0.058) and significantly reduced salivation (p=0.001), but these effects were not related to cue type. Conclusions This study provides preliminary evidence suggesting a possible role of baclofen in the treatment of alcoholic smokers. However, the mixed results and the small sample require larger confirmatory studies. PMID:24973894

2015-02-01

Alcohol dependence (AD) has global effects on brain structure and function, including frontolimbic regions regulating affective processing. Preliminary evidence suggests alcohol blunts limbic response to negative affective stimuli and increases activation to positive affective stimuli. Subtle gender differences are also evident during affective processing. Fourteen abstinent AD individuals (8 F, 6 M) and 14 healthy controls (9 F, 5 M), ages 23 to 60, were included in this facial affective processing functional magnetic resonance imaging pilot study. Whole-brain linear regression analyses were performed, and follow-up analyses examined whether AD status significantly predicted depressive symptoms and/or coping. Fearful Condition-The AD group demonstrated reduced activation in the right medial frontal gyrus, compared with controls. Gender moderated the effects of AD in bilateral inferior frontal gyri. Happy Condition-AD individuals had increased activation in the right thalamus. Gender moderated the effects of AD in the left caudate, right middle frontal gyrus, left paracentral lobule, and right lingual gyrus. Interactive AD and gender effects for fearful and happy faces were such that AD men activated more than control men, but AD women activated less than control women. Enhanced coping was associated with greater activation in right medial frontal gyrus during fearful condition in AD individuals. Abnormal affective processing in AD may be a marker of alcoholism risk or a consequence of chronic alcoholism. Subtle gender differences were observed, and gender moderated the effects of AD on neural substrates of affective processing. AD individuals with enhanced coping had brain activation patterns more similar to controls. Results help elucidate the effects of alcohol, gender, and their interaction on affective processing.

In an urban emergency department on weekend nights in 2010 and 2011, 105 interviews assessed feasibility of collecting alcohol brand consumption data from injured patients who drank within 6 h of presentation, with responses to the orally administered survey specifying 331 alcohol brands recorded on a netbook computer. A Kruskal-Wallis test adjusted for tied ranks assessed demographic differences; confidence intervals were created around comparisons with national brand shares. The study found collection of such information feasible; limitations include comparison of national brand market share data with a local sample of drinkers.

Viewing alcohol warning advertising reduces urges to drink in young adults: an online experiment.

PubMed

Stautz, Kaidy; Marteau, Theresa M

2016-07-08

Tobacco counter-advertising is effective at promoting smoking cessation. Few studies have evaluated the impact of alcohol warning advertising on alcohol consumption and possible mechanisms of effect. This pilot study aimed to assess whether alcohol warning advertising is effective in reducing urges to drink alcohol, if emotional responses to advertising explain any such effect or perceived effectiveness, and whether effects differ among heavier drinkers. One hundred fifty-two young adult (aged 18-25) alcohol users completed an online experiment in which they were randomly assigned to view one of three sets of six advertisements: (i) alcohol warning; (ii) alcohol promoting; or (iii) advertisements for non-alcohol products. Urges to drink alcohol were self-reported post-exposure. Affective responses (pleasure and arousal) to each advertisement and perceived effectiveness of each advertisement were recorded. Typical level of alcohol consumption was measured as a potential effect modifier. Participants exposed to alcohol warning advertisements reported significantly lower urges to drink alcohol than those who viewed either alcohol promoting or non-alcohol advertisements. This effect was fully mediated by negative affective responses (displeasure) to the alcohol warning advertisements. Perceived effectiveness of alcohol warning advertisements was associated with high arousal responses. Impact of the advertisements was unaffected by typical level of alcohol consumption, although the study was not powered to detect anything other than large effects. In line with findings from the tobacco literature, alcohol warning advertisements that elicit negative affect reduce urges to drink alcohol. Their impact upon actual consumption awaits investigation.

Animal studies suggest that the gut-brain peptide ghrelin plays an important role in the neurobiology of alcohol dependence (AD). Human studies show an effect of alcohol on ghrelin levels and a correlation between ghrelin levels and alcohol craving in alcoholics. This investigation consisted of two studies. Study 1 was a 12-week study with alcohol-dependent subjects, where plasma ghrelin determinations were assessed four times (T0-T3) and related to alcohol intake and craving [Penn Alcohol Craving Score (PACS) and Obsessive Compulsive Drinking Scale (OCDS)]. Serum growth hormone levels and assessment of the nutritional/metabolic status were also performed. Study 2 was a pilot case-control study to assess ghrelin gene polymorphisms (Arg51Gln and Leu72Met) in alcohol-dependent individuals. Study 1 showed no significant differences in ghrelin levels in the whole sample, while there was a statistical difference for ghrelin between non-abstinent and abstinent subjects. Baseline ghrelin levels were significantly and positively correlated with the PACS score at T1 and with all craving scores both at T2 and T3 (PACS, OCDS, obsessive and compulsive OCDS subscores). In Study 2, although there was a higher frequency of the Leu72Met ghrelin gene polymorphism in alcohol-dependent individuals, the distribution between healthy controls and alcohol dependent individuals was not statistically significant. This investigation suggests that ghrelin is potentially able to affect alcohol-seeking behaviors, such as alcohol drinking and craving, representing a new potential neuropharmacological target for AD. © 2011 The Authors, Addiction Biology © 2011 Society for the Study of Addiction.

There are no biological treatments for fetal alcohol spectrum disorders (FASDs), lifelong conditions associated with physical anomalies, brain damage, and neurocognitive abnormalities. In preclinical studies, choline partially ameliorates memory and learning deficits from prenatal alcohol exposure. This phase I pilot study evaluated the feasibility, tolerability, and potential adverse effects of choline supplementation in children with FASD. We hypothesized that choline would be well tolerated with minimal adverse events. The study design was a double-blind, randomized, placebo-controlled trial. Participants included 20 children aged 2.5 to 4.9 years with prenatal alcohol exposure and FASD diagnoses. Participants were randomly assigned to 500 mg choline or placebo daily for 9 months (10 active, 10 placebo). Primary outcome measures included feasibility, tolerability, adverse effects, and serum choline levels. Seventeen participants completed the study. Compliance was 82% to 87%, as evidenced by parent-completed log sheets and dose counts. Periodic 24-hour dietary recalls showed no evidence of dietary confounding. Adverse events were minimal and were equivalent in the active and placebo arms with the exception of fishy body odor, which occurred only in the active group. There were no serious adverse events to research participants. This phase I pilot study demonstrates that choline supplementation at 500 mg/d for 9 months in children aged 2 to 5 years is feasible and has high tolerability. Further examination of the efficacy of choline supplementation in FASD is currently underway. © 2013.

[Neuromodulation as an intervention for addiction: overview and future prospects].

Luigjes, J; Breteler, R; Vanneste, S; de Ridder, D

2013-01-01

In recent years several neuromodulation techniques have been introduced as interventions for addiction. To review and discuss studies that have investigated the effects of treating addiction by means of electroencephalography (EEG) neurofeedback, real-time functional magnetic resonance imaging (rt-fMRI) neurofeedback, transcranial magnetic stimulation/transcranial direct current stimulation (TMS/tDCS) and deep brain stimulation (DBS). We reviewed the literature, focusing on Dutch studies in particular. Studies using EEG neurofeedback were shown to have positive effects on drug use, treatment compliance, and cue reactivity in patients with cocaine and alcohol dependence. A pilot study investigating the effects of rt-fMRI neurofeedback on nicotine dependent patients showed that modulation of the anterior cingulate cortex can decrease smokers' craving for nicotine. In several studies decreased craving was found in alcohol dependent patients after TMS or tDCS stimulation of the anterior cingulate cortex or the dorsolateral prefrontal cortex. The first DBS pilot studies suggest that the nucleus accumbens is a promising target region for the treatment of alcohol and heroin dependence. Neuromodulation provides us with a unique opportunity to directly apply neuroscientific knowledge to the treatment of addiction. However, more research is needed to ensure the efficacy, safety and feasibility of the various neuromodulation techniques that are now available.

Many of the problems associated with alcohol occur after a single drinking event (e.g. drink driving, assault). These acute alcohol problems have a huge global impact and account for a large percentage of unintentional and intentional injuries in the world. Nonetheless, alcohol research and preventive interventions rarely focus on drinking at the event-level since drinking events are complex, dynamic, and methodologically challenging to observe. This exploratory study provides an example of how event-level data may be collected, analyzed, and interpreted. The drinking behavior of twenty undergraduate students enrolled at a large Midwestern public university was observed during a single bar crawl event that is organized by students annually. Alcohol use was monitored with transdermal alcohol devices coupled with ecological momentary assessments and geospatial data. "Small N, Big Data" studies have the potential to advance health behavior theory and to guide real-time interventions. However, such studies generate large amounts of within subject data that can be challenging to analyze and present. This study examined how to visually display event-level data and also explored the relationship between some basic indicators and alcohol consumption.

In the US, Mexican immigrant women often have better health outcomes than non-Hispanic white women despite a greater health risk profile. This cross-sectional pilot study compared women living in Chavinda, Michoacán (n = 102) to women who had migrated from Mexico to Madera, California (n = 93). The interview gathered information on acculturation and risk behaviors including smoking, alcohol use and number of sexual partners. The results suggest that more acculturated women living in the US are more likely to consume alcohol. US residence and higher acculturation level was marginally associated with having more than one sexual partner. There were no differences between odds of smoking among Chavinda and Madera women. While results with acculturation are not consistently significant due to small sample sizes, the results are suggestive that acculturation among immigrant Hispanic women in the US may be associated with adverse health behaviors, and selective migration seems less likely to account for these differences.

This study was aimed at investigating the caries status of Chinese civilian pilots and the relationship between caries and oral health behaviors, including sugar intake, smoking, alcohol consumption, tooth brushing, and dental check-up attendance. This cross-sectional investigation enrolled pilots from Shenzhen Airline. A questionnaire was used to collect general information and oral health behaviors. The Decayed, Missing, and Filled Teeth (DMFT) Index, International Caries Detection and Assessment System (ICDAS) II, caries prevalence, and rate of missing teeth were recorded via oral examination. Rank correlation was used to reveal the correlation between caries and oral health behavior. All of the pilots were men ages 21-58 yr (mean, 31.48 ± 7.20). In the caries group (CG), the frequency of tooth brushing and flossing was a little higher; more subjects had already given up smoking; more subjects had higher alcohol consumption; the sugar intake index (SII) was a little bit higher; and the last dental attendance time (LDAT) was shorter than that in the noncaries group (NCG). A total of 211 pilots (37.95%) had caries and 85 (15.29%) had missing teeth. The average DMFT was 2.19, while the mean ICDAS was 0.72. The frequency of sugary beverage consumption was negatively correlated with caries (r = -0.088), while a positive relationship was found between LDAT and caries (r = 0.094). Chinese civilian pilots have relatively good oral hygiene behavior and dental health. A relationship was found between sugary beverage consumption/LDAT and caries.

Background Alcohol dependence (AD) has global effects on brain structure and function, including frontolimbic regions regulating affective processing. Preliminary evidence suggests alcohol blunts limbic response to negative affective stimuli and increases activation to positive affective stimuli. Subtle gender differences are also evident during affective processing. Methods Fourteen abstinent AD individuals (8 F, 6 M) and 14 healthy controls (9 F, 5 M), ages 23 to 60, were included in this facial affective processing functional magnetic resonance imaging pilot study. Whole-brain linear regression analyses were performed, and follow-up analyses examined whether AD status significantly predicted depressive symptoms and/or coping. Results Fearful Condition—The AD group demonstrated reduced activation in the right medial frontal gyrus, compared with controls. Gender moderated the effects of AD in bilateral inferior frontal gyri. Happy Condition—AD individuals had increased activation in the right thalamus. Gender moderated the effects of AD in the left caudate, right middle frontal gyrus, left paracentral lobule, and right lingual gyrus. Interactive AD and gender effects for fearful and happy faces were such that AD men activated more than control men, but AD women activated less than control women. Enhanced coping was associated with greater activation in right medial frontal gyrus during fearful condition in AD individuals. Conclusions Abnormal affective processing in AD may be a marker of alcoholism risk or a consequence of chronic alcoholism. Subtle gender differences were observed, and gender moderated the effects of AD on neural substrates of affective processing. AD individuals with enhanced coping had brain activation patterns more similar to controls. Results help elucidate the effects of alcohol, gender, and their interaction on affective processing.

Individuals with fetal alcohol spectrum disorders (FASD) are at high risk for costly, debilitating mental health problems and secondary conditions, such as school disruption, trouble with the law, and substance use. The study objective was to pilot a multicomponent intervention designed to prevent secondary conditions in children with FASD and improve family adaptation. Thirty children with FASD or prenatal alcohol exposure (PAE) (ages 4 to 8) and their primary caregivers were enrolled. Families were randomized to either the Families on Track Integrated Preventive Intervention or an active control of neuropsychological assessment and personalized community referrals. The 30-week intervention integrates scientifically validated bimonthly, in-home parent behavioral consultation, and weekly child skills groups. Outcomes measured at baseline and follow-up postintervention included intervention satisfaction, child emotional and behavioral functioning, child self-esteem, caregiver knowledge of FASD and advocacy, caregiver attitudes, use of targeted parenting practices, perceived family needs met, social support, and self-care. Data analysis emphasized calculation of effect sizes and was supplemented with analysis of variance techniques. Analyses indicated that families participating in the intervention reported high program satisfaction. Relative to comparison group outcomes, the intervention was associated with medium-to-large effects for child emotion regulation, self-esteem, and anxiety. Medium-sized improvements in disruptive behavior were observed for both groups. Medium and large effects were seen for important caregiver outcomes: knowledge of FASD and advocacy, attributions of behavior, use of antecedent strategies, parenting efficacy, family needs met, social support, and self-care. This pilot study yielded promising findings from the multicomponent Families on Track Integrated Preventive Intervention for child and caregiver outcomes. An important next step is to complete a randomized control trial of the Families on Track Program with a larger sample fully representative of this underserved clinical population with built-in study of implementation parameters.

2013-01-01

Ending homelessness is a major priority of the Department of Veteran Affairs (VA), and alcohol use can be a barrier to stable housing. Clinical trials suggest that depot extended-release naltrexone (XR-NTX) is efficacious in reducing alcohol consumption among alcohol-dependent subjects. An open-label, randomized pilot study sought to examine the feasibility and effectiveness of XR-NTX versus oral naltrexone to improve alcohol consumption and housing stability among homeless, alcohol-dependent veterans at the Providence Veteran Affairs Medical Center. Of 215 potential candidates approached over a 16-month recruitment period, only 15 agreed to consider study entry and 7 were randomized. The primary reasons given for refusal were not wanting an injection; fear of needles; and not wanting to change drinking habits. Only 1 participant in the XR-NTX group returned after the first injection. Three participants in the oral naltrexone group attended all 7 visits and had good outcomes. Although XR-NTX has demonstrated efficacy in reducing heavy drinking, limited acceptance of the injection might reduce its effectiveness among homeless, alcohol-dependent patients.

The Influence of Parental Emotional Neglect on Assault Victims Seeking Treatment for Depressed Mood and Alcohol Misuse: A Pilot Study.

Bailey, Kylie A; Baker, Amanda L; McElduff, Patrick; Kavanagh, David J

2016-10-09

This study explores the relationship between reported parental emotional neglect when a child, assault type experienced, posttraumatic stress symptoms (PTSS), depression, and alcohol consumption in treatment seekers for comorbid depressive symptoms and alcohol misuse. Participants ( n = 220) with concurrent depression and alcohol misuse were recruited from the DAISI (Depression and Alcohol Integrated and Single-focussed Interventions) project. Assault type and PTSS were retrospectively assessed by the Posttraumatic Stress Diagnostic Scale. The Measure of Parenting Style is a self-report measure that retrospectively assessed emotional neglect experienced as a child. An exploratory factor analysis using the tetrachoric correlation matrix (applying principal factor extraction with a varimax rotation) identified the two assault factors of sexual assault ( SA ) and physical assault ( PA ). A path analysis revealed that Maternal Emotional Neglect increased the impact of PTSS and depression. Paternal Emotional Neglect increased the impact of PA on PTSS and alcohol dependence symptoms. There appears to be differential effects of assault type and Maternal/Paternal emotional neglect on depression and alcohol misuse, suggesting that parenting roles serve distinct protective functions.

The objective of this study is to determine risk factors for fatigue among airline pilots, taking into account person-, work-, health-, sleep-, and lifestyle-related characteristics. The study population consisted of 502 pilots who participated in the MORE Energy study. Included risk factors were either measured through an online questionnaire or provided by the company. The outcome of this study, fatigue, was assessed using the Checklist Individual Strength (CIS), and was defined as scoring more than 76 points on this questionnaire. The association of the risk factors with fatigue was determined using univariate and multivariate logistic regression analyses. Of the participating pilots, 29.5 % scored more than 76 points on the CIS and were classified as being fatigued. The fully adjusted regression model showed that person-, work-, health-, and lifestyle-related characteristics were associated with fatigue. Pilots who were aged 31 to 40 (OR 3.36, 95 % CI 1.32-8.53) or 41 to 50 (OR 4.19, 95 % CI 1.40-12.47), an evening type (OR 2.40, 95 % CI 1.38-4.16), scored higher on work-life balance disturbance (OR 1.22, 95 % CI 1.10-1.36), scored higher on need for recovery (OR 1.02, 95 % CI 1.01-1.04), scored lower on general health perception (OR 0.31, 95 % CI 0.20-0.47), were less physically active (OR 0.77, 95 % CI 0.66-0.89), and had a moderate alcohol consumption (OR 3.88, 95 % CI 1.21-12.43), were at higher risk for fatigue. Higher age, being an evening type, disturbance of the work-life balance, more need for recovery, a lower perceived health, less physical activity, and moderate alcohol consumption were shown to be risk factors for fatigue. Further longitudinal research is needed to elucidate the direction of the associations found and to evaluate the effects of possible countermeasures in airline pilots.

Scant research has been conducted on neural mechanisms underlying stress processing in individuals with alcohol dependence (AD). We examined neural substrates of stress in AD individuals compared with controls using an fMRI task previously shown to induce stress, assessing amygdala functional connectivity to medial prefrontal cortex (mPFC). For this novel pilot study, 10 abstinent AD individuals and 11 controls completed a modified Trier stress task while undergoing fMRI acquisition. The amygdala was used as a seed region for whole-brain seed-based functional connectivity analysis. After controlling for family-wise error (p = 0.05), there was significantly decreased left and right amygdala connectivity with frontal (specifically mPFC), temporal, parietal, and cerebellar regions. Subjective stress, but not craving, increased from pre-to post-task. This study demonstrated decreased connectivity between the amygdala and regions important for stress and emotional processing in long-term abstinent individuals with AD. These results suggest aberrant stress processing in individuals with AD even after lengthy periods of abstinence.

Managed alcohol programs (MAPs) are a harm reduction strategy for people with severe alcohol dependence and unstable housing. MAPs provide controlled access to alcohol usually alongside accommodation, meals, and other supports. Patterns of alcohol consumption and related harms among MAP participants and controls from a homeless shelter in Thunder Bay, Ontario, were investigated in 2013. Structured interviews were conducted with 18 MAP and 20 control participants assessed as alcohol dependent with most using non-beverage alcohol (NBA). Qualitative interviews were conducted with seven participants and four MAP staff concerning perceptions and experiences of the program. Program alcohol consumption records were obtained for MAP participants, and records of police contacts and use of health services were obtained for participants and controls. Some participants' liver function test (LFT) results were available for before and after MAP entry. Compared with periods off the MAP, MAP participants had 41 % fewer police contacts, 33 % fewer police contacts leading to custody time (x (2) = 43.84, P < 0.001), 87 % fewer detox admissions (t = -1.68, P = 0.06), and 32 % fewer hospital admissions (t = -2.08, P = 0.03). MAP and control participants shared similar characteristics, indicating the groups were broadly comparable. There were reductions in nearly all available LFT scores after MAP entry. Compared with controls, MAP participants had 43 % fewer police contacts, significantly fewer police contacts (-38 %) that resulted in custody time (x (2) = 66.10, P < 0.001), 70 % fewer detox admissions (t = -2.19, P = 0.02), and 47 % fewer emergency room presentations. NBA use was significantly less frequent for MAP participants versus controls (t = -2.34, P < 0.05). Marked but non-significant reductions were observed in the number of participants self-reporting alcohol-related harms in the domains of home life, legal issues, and withdrawal seizures. Qualitative interviews with staff and MAP participants provided additional insight into reductions of non-beverage alcohol use and reductions of police and health-care contacts. It was unclear if overall volume of alcohol consumption was reduced as a result of MAP participation. The quantitative and qualitative findings of this pilot study suggest that MAP participation was associated with a number of positive outcomes including fewer hospital admissions, detox episodes, and police contacts leading to custody, reduced NBA consumption, and decreases in some alcohol-related harms. These encouraging trends are being investigated in a larger national study.

Seventy-four pilots were monitored before, during, and after 3- or 4-day commercial short-haul trip patterns. The trips studied averaged 10.6 hr of duty per day with 4.5 hr of flight time and 5.5 flight segments. The mean rest period lasted 12.5 hr and occurred progressively earlier across successive days. On trip nights, subjects took longer to fall asleep, slept less, woke earlier, and reported lighter, poorer sleep with more awakenings than on pretrip nights. During layovers, subjective fatigue and negative affect were higher, and positive affect and activation lower, than during pretrip, in-flight, or posttrip. Pilots consumed more caffeine, alcohol, and snacks on trip days than either pretrip or posttrip. Increases in heart rate over mid-cruise were observed during descent and landing, and were greater for the pilot flying. Heart-rate increases were greater during takeoff and descent under instrument meteorological conditions (IMC) than under visual meteorological conditions (VMC). The following would be expected to reduce fatigue in short-haul operations: regulating duty hours, as well as flight hours; scheduling rest periods to begin at the same time of day, or progressively later, across the days of a trip; and educating pilots about alternatives to alcohol as a means of relaxing before sleep.

Objective To determine whether drivers contacted at the roadside can be screened for alcohol use disorders (AUDs). Secondarily, to produce preliminary estimates of AUDs among drivers and estimate the relationship between AUD status and BAC measured at the roadside. Methods A two-phase survey program was undertaken. In phase 1, 206 motorists were interviewed at the roadside using a 15-item AUD Survey derived from a condensed version of the AUDADIS and the AUDIT-C. One hundred sixty-seven of these motorists were invited, for a $25 incentive, to call the research team within 48 hours of the roadside assessment to repeat the questionnaire and complete a more detailed AUD assessment. Phase 2 involved a six-state pilot test of the AUD Survey as an add-on to the 2005 National Roadside Survey Pilot Program. The setting for both phases of the survey program was U.S. roadways on weekends between 10 p.m. and 3 a.m. Results Ninety-seven percent of all eligible drivers completed the AUD questionnaire. The correlation between roadside and telephone interview results was 0.3 for alcohol abuse, 0.6 for alcohol dependence and heavy drinking, and 0.7 for binge drinking. Alcohol abuse and dependence diagnoses had 0.6 and 0.7 correlation with diagnoses derived from the full AUDADIS and the AUDIT-C had a 0.8 correlation with the full AUDIT. There was also a statistically significant and positive relationship between having a positive BAC at the roadside and meeting criteria for heavy drinking. Conclusions AUD status can be effectively measured at the roadside. The poor reliability for alcohol abuse is related to underreporting of drinking and driving during roadside assessments, compared to telephone follow up. Other measures of hazardous alcohol use should be used in the roadside context to measure alcohol abuse. PMID:19746302

Physicians in emergency departments (EDs) treat more patients with alcohol-related disorders than do those in primary care settings. To implement an effective screening, brief intervention, and referral (SBIR) program for use in EDs. Further, to evaluate the impact of the program on alcohol-consumption levels. A prospective cohort pilot study was conducted at a suburban community teaching hospital using a convenience sample of ED patients and an original seven-question screening tool based on well-known guidelines. Subjects screening positive for possible alcohol abuse were given treatment referrals. Follow-up telephone interviews were conducted 6 months later. Of the 1556 enrolled subjects, 251 (16%) were classified as at-risk drinkers. Seventy-nine at-risk subjects (32% [95% CI, 26%-37%]) screened positive on CAGE-based questions (Cut down, Annoyed, Guilty, Eye opener). At follow-up, 20 (25% [95% CI, 16%-35%]) were successfully contacted. Of these 20 subjects, 5 (25%) refused to participate in follow-up screening. For the remaining 15 individuals, follow-up screening indicated that the mean (SD) number of drinks consumed per week decreased from 28 (14) on study enrollment to 10 (10) at 6-month follow-up (P<.001). Maximum number of drinks per occasion decreased from 12 (8) at enrollment to 6 (7) on follow-up (P=.008). Subject scores on the CAGE-based questions decreased from pre- to postintervention, though not significantly, with an average of 2.1 (1) affirmative answers on enrollment and 1.5 (1.4) at follow-up (P=.108). Implementation of an effective SBIR program for alcohol-related disorders can be accomplished in the ED.

2006-05-01

Our objective is to estimate the relative price elasticity of demand for malt liquor beer (MLB), regular beer, hard liquor, and a combined group of all other alcoholic beverages. Three hundred and twenty-nine alcohol consumers (mostly male) in South-Central Los Angeles answered a series of questions pertaining to expected consumption responses to hypothetical price increases. We found that based on a 10% price increase, the mean price elasticity of demand (% change in quantity demanded / % change in price) was -0.79 for MLB drinkers, -1.14 for regular beer drinkers, -1.11 for hard liquor drinkers, and -1.69 for the combined group of all other drinkers. Logistic regression analysis revealed that the personal characteristics significantly related to being a MLB drinker were older age, not working, being homeless, and a daily drinker. Daily (or nearly daily) drinkers were more likely to be married, earning lower incomes, and hard liquor drinkers. This study is the first to investigate the price elasticity of demand for MLB drinkers and other heavy alcohol consumers in poor urban neighborhoods of the US. Future research can use the methods from this pilot study to more rigorously examine and compare the price sensitivity among heavy drinking groups.

Alcohol use disorder is underdiagnosed and undertreated, and up to 50% of alcohol-abstinent patients diagnosed with alcohol dependence relapse within the first year of treatment. Current treatments for the maintenance of alcohol abstinence in patients with alcohol use disorder have limited efficacy, and there is an urgent need for novel treatment strategies. Decreased cerebral glucose metabolism and increased brain uptake of acetate were recently reported in heavy drinkers, relative to controls. Given the switch of metabolic fuel from glucose to acetate in the alcohol-dependent brain, we investigated the potential therapeutic benefit of a ketogenic diet in managing alcohol withdrawal symptoms during detoxification. Male Sprague Dawley rats fed either ketogenic or regular diet were administered ethanol or water orally, twice daily for 6 days while the diet conditions were maintained. Abstinence symptoms were rated 6, 24, 48, and 72 hours after the last alcohol administration. Maintenance on a ketogenic diet caused a significant decrease in the alcohol withdrawal symptoms' "rigidity" and "irritability." Our preclinical pilot study suggests that a ketogenic diet may be a novel approach for treating alcohol withdrawal symptoms in humans. Copyright © 2017 by the Research Society on Alcoholism.

Some European countries with high levels of unrecorded alcohol consumption have anomalously high rates of death attributable to liver cirrhosis. Hepatotoxic compounds in illegally produced spirits may be partly responsible. Based on a review of the evidence on the chemical composition and potential harm from unrecorded alcohol, the Alcohol Measures for Public Health Research Alliance (AMPHORA) project's methodology for identifying, analysing and toxicologically evaluating such alcohols is provided. A computer-assisted literature review concentrated on unrecorded alcohol. Additionally, we refer to our work in the capacity of governmental alcohol control authority and a number of pilot studies. The risk-oriented identification of substances resulted in the following compounds probably posing a public health risk in unrecorded alcohol: ethanol, methanol, acetaldehyde, higher alcohols, heavy metals, ethyl carbamate, biologically active flavourings (e.g. coumarin) and diethyl phthalate. Suggestions on a sampling strategy for identifying unrecorded alcohol that may be most prone to contamination include using probable distribution points such as local farmers and flea markets for selling surrogate alcohol (including denatured alcohol) to focusing on lower socio-economic status or alcohol-dependent individuals, and selecting home-produced fruit spirits prone to ethyl carbamate contamination. Standardized guidelines for the chemical and toxicological evaluation of unrecorded alcohol that will be used in a European-wide sampling and are applicable globally are provided. These toxicological guidelines may also be used by alcohol control laboratories for recorded alcohol products, and form a scientific foundation for establishing legislative limits. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

The national alcohol helpline in Sweden: an evaluation of its first year

PubMed Central

2014-01-01

Background Telephone helplines are easily available and can offer anonymity. Alcohol helplines may be a potential gateway to a more advanced support protocol, and they may function as a primary support option for some. However, although telephone helplines (quitlines) make up an established evidence-based support arena for smoking cessation, few studies have described such telephone-based alcohol counseling. Methods This study describes the basic characteristics of callers (n = 480) to the Swedish Alcohol Helpline during its first year of operation, and assesses aspects of change in alcohol behavior in a selected cohort of clients (n = 40) willing to abstain from anonymity and enter a proactive support protocol. Results During the study period, 50% of callers called for consultation regarding their own alcohol use (clients), a third called about relatives with alcohol problems, and the others called for information. The clients’ average age was 49 years, and half were females. The clients’ average AUDIT score at baseline was 21 (std. dev. =7.2). Approximately a quarter had scores indicating hazardous alcohol use at baseline, while the others had higher scores. In a follow-up pilot study, the average AUDIT score had decreased from 21 to 14. While clients reporting more severe alcohol use showed a significant decrease at follow-up, hazardous users exhibited no change during the study period. Conclusion The study indicates that telephone helplines addressing the general public can be a primary-care option to reduce risky alcohol use. A randomized controlled study is needed to control for the effect of spontaneous recovery. PMID:25015403

[Effect of alcohol intake on the ability to pilot aircraft].

PubMed

Ushakov, I B; Egorov, S V

1996-01-01

During the initial 4 hours after alcohol intake at a dose of 1.9 g/kg aircraft operators displayed disturbances in the psychic processes and functions responsible for each (from information reception and processing up to decision-making and building-up the controlling actions) structural elements in their activity resulting in considerable limitation or a complete failure to pilot aircraft. Main disorders included inability to correctly analyse flight situation and loss of skills to automatically control simulator, a sudden depletion of psychophysiological reserves and deterioration of operator's reliability. Less elaborated professional skills appear to be the most vulnerable.

Environmental auditing is an important tool to ensure consistent and effective cleaning. Our pilot study compared an alcohol-based fluorescent marking product and an adenosine-5'-triphosphate bioluminescence product for use in an environmental auditing program to determine which product was more practical and acceptable to users. Both products were tested on 15 preselected high touch objects in randomly selected patient rooms, following regular daily cleaning. A room was considered a "pass" if ≥80% of surfaces were adequately cleaned as defined by manufacturers' guidelines. A qualitative survey assessed user preference and operational considerations. Using fluorescent marking, 9 of 37 patient rooms evaluated (24%) were considered a "pass" after daily cleaning. Using adenosine-5'-triphosphate bioluminescence, 21 of 37 patient rooms passed (57%). There was great variability in results between different high touch objects. Eighty percent of users preferred the alcohol-based fluorescent marking product because it provided an effective visual aid to coach staff on proper cleaning techniques and allowed simple and consistent application. Environmental auditing using translucent, alcohol-based fluorescent marking best met the requirements of our organization. Our results reinforce the importance of involving a multidisciplinary team in evaluating and operationalizing an environmental auditing program.

Individuals transitioning from homelessness to housing face challenges to reducing alcohol, drug and HIV risk behaviors. To aid in this transition, this study developed and will test a computer-assisted intervention that delivers personalized social network feedback by an intervention facilitator trained in motivational interviewing (MI). The intervention goal is to enhance motivation to reduce high risk alcohol and other drug (AOD) use and reduce HIV risk behaviors. In this Stage 1b pilot trial, 60 individuals that are transitioning from homelessness to housing will be randomly assigned to the intervention or control condition. The intervention condition consists of four biweekly social network sessions conducted using MI. AOD use and HIV risk behaviors will be monitored prior to and immediately following the intervention and compared to control participants' behaviors to explore whether the intervention was associated with any systematic changes in AOD use or HIV risk behaviors. Social network health interventions are an innovative approach for reducing future AOD use and HIV risk problems, but little is known about their feasibility, acceptability, and efficacy. The current study develops and pilot-tests a computer-assisted intervention that incorporates social network visualizations and MI techniques to reduce high risk AOD use and HIV behaviors among the formerly homeless.

Alcohol and energy drinks: a pilot study exploring patterns of consumption, social contexts, benefits and harms

PubMed Central

2012-01-01

Background Young people around the world are increasingly combining alcohol with energy drinks (AEDs). However, as yet, limited research has been conducted examining this issue, particularly in terms of exploring patterns of consumption, social practices and the cultural contexts of AED consumption. We sought to understand how AEDs are used and socially constructed among young people. Methods We conducted 25 hours of observation in a variety of pubs, bars and nightclubs, as well as in-depth interviews with ten young people who regularly consumed AEDs during a session of alcohol use. Results In this pilot study, participants were highly organised in their AED consumption practices and reported rarely altering this routine. Some young people consumed upwards of eight AEDs on a typical night, and others limited their use to between three and five AEDs to avoid unpleasant consequences, such as sleep disturbances, severe hangovers, heart palpitations and agitation. Wakefulness and increased energy were identified as the primary benefits of AEDs, with taste, reduced and increased intoxication, and sociability reported as additional benefits. Young AED users were brand sensitive and responded strongly to Red Bull imagery, as well as discounted AEDs. Finally, some young people reported substituting illicit stimulants with energy drinks. Conclusions Combining energy drinks with alcohol is now a normalised phenomenon and an integral and ingrained feature of the night-time economy. Despite this, many young people are unaware of recommended daily limits or related harms. While some young people consume AEDs to feel less drunk (consistent with motivations for combining alcohol with illicit stimulants), others report using AEDs to facilitate intoxication. While preliminary, our findings have relevance for potential policy and regulatory approaches, as well as directions for future research. PMID:22824297

Barnett, Nancy P.; Tidey, Jennifer; Murphy, James G.; Swift, Robert; Colby, Suzanne M.

2011-01-01

Background Contingency management (CM) has not been thoroughly evaluated as a treatment for alcohol abuse or dependence, in part because verification of alcohol use reduction requires frequent in-person breath tests. Transdermal alcohol sensors detect alcohol regularly throughout the day, providing remote monitoring and allowing for rapid reinforcement of reductions in use. Methods The purpose of this study was to evaluate the efficacy of CM for reduction in alcohol use, using a transdermal alcohol sensor to provide a continuous measure of alcohol use. Participants were 13 heavy drinking adults who wore the Secure Continuous Remote Alcohol Monitoring (SCRAM) bracelet for three weeks and provided reports of alcohol and drug use using daily web-based surveys. In Week 1, participants were asked to drink as usual; in Weeks 2 and 3, they were reinforced on an escalating schedule with values ranging from $5-$17 per day on days when alcohol use was not reported or detected by the SCRAM. Results Self-reports of percent days abstinent and drinks per week, and transdermal measures of average and peak transdermal alcohol concentration and area under the curve declined significantly in Weeks 2-3. A nonsignificant but large effect size for reduction in days of tobacco use also was found. An adjustment to the SCRAM criteria for detecting alcohol use provided an accurate but less conservative method for use with non-mandated clients. Conclusion Results support the efficacy of CM for alcohol use reductions and the feasibility of using transdermal monitoring of alcohol use for clinical purposes. PMID:21665385

The AUDIT-like tests system was created for complex assessment and evaluation of the addictive status of adolescents in a Ukrainian population. The AUDIT-like tests system has been created from the Alcohol Use Disorders Identification Test (AUDIT) developed by the World Health Organization. The AUDIT-like tests were minimally modified from the original AUDIT. Attention was brought to similarities between stages of different addictions (TV, computer games, the Internet, etc.) and alcohol addiction. Seventeen AUDIT-like tests were created to detect the different types of chemical and non-chemical addictions.

 Type 1 diabetes (T1D) care requires multiple daily self-management behaviors (SMBs). Preliminary studies on SMBs rely mainly on self-reported survey and interview data. There is little information on adult T1D SMBs, along with corresponding compensation techniques (CTs), gathered in real-time.  The article aims to use a patient-centered approach to design iDECIDE, a smartphone application that gathers daily diabetes SMBs and CTs related to meal and alcohol intake and exercise in real-time, and contrast patients' actual behaviors against those self-reported with the app.  Two usability studies were used to improve iDECIDE's functionality. These were followed by a 30-day pilot test of the redesigned app. A survey designed to capture diabetes SMBs and CTs was administered prior to the 30-day pilot test. Survey results were compared against iDECIDE logs.  Usability studies revealed that participants desired advanced features for self-tracking meals and alcohol intake. Thirteen participants recorded over 1,200 CTs for carbohydrates during the 30-day study. Participants also recorded 76 alcohol and 166 exercise CTs. Comparisons of survey responses and iDECIDE logs showed mean% (standard deviation) concordance of 77% (25) for SMBs related to meals, where concordance of 100% indicates a perfect match. There was low concordance of 35% (35) and 46% (41) for alcohol and exercise events, respectively.  The high variability found in SMBs and CTs highlights the need for real-time diabetes self-tracking mechanisms to better understand SMBs and CTs. Future work will use the developed app to collect SMBs and CTs and identify patient-specific diabetes adherence barriers that could be addressed with individualized education interventions.

The work force in industries are at risk of developing unduly high rates of health and behaviour related problems including abuse of alcohol, betel nut and cigarette (alcohol, betel nut and cigarette consumption). This study describes the relationships between alcohol, betel nut and cigarette consumption and health promoting behaviour among industrial workers. A cross sectional survey was conducted on workers in various industries of Ghaziabad city with concerned authority permission. A sample size of 732 workers was calculated based on pilot study. Through Simple random sampling 732 workers in 20 to 50 years age group with informed consent were interviewed through structured, pretested, validated questionnaire in vernacular language by one calibrated investigator. Data on socio demography, alcohol, betel nut and cigarette consumption pattern and health behaviour were collected. The association between health promoting behaviour and alcohol, betel nut and cigarette consumption was analysed by Logistic regression and Chi-square test through SPSS 16 at p<0.05 and 95%CI as significant. Total prevalence of alcohol, betel nut and cigarette consumption in study population was 88%. The prevalence of individual alcohol, betel nut and cigarette consumption were 82%, 68% and 79% respectively. Combined alcohol, betel nut and cigarette prevalence in study population was 58%. Alcohol and cigarette users were significantly higher (p<0.001) in 30 to 40 years age group with lower level of education having poor attitude towards health promoting behaviour, poor oral hygiene practices and rare indulgence in regular physical exercise. This study stimulate further research on exploring methods to prevent initiation of health risk behaviour and promote healthy behaviour with cessation help for the current alcohol, betel nut and cigarette users.

A total of 36 alcohol dependents completed the study and questionnaires assessing their state. A single session of AAI reduced both subjective and physiological measures of state anxiety (A-State); and this program induced a significant reduction in the anxiety after an AAI program session with the dogs and cats involved in the intervention (p = 0.001). The Wilcoxon t-test showed that there were also significant differences in the "anxiety", "pleasantness", and "relaxation". scores for MCL-S.2 among the alcohol dependents, before and after AAI; a significantly decreased "anxiety" score (p = 0.006), and increased "pleasantness" (p = 0.002) and "relaxation" (p=0.012) scores for MCL-S.2 after AAI. The results of this study indicated that alcohol dependents who experienced a group AAI session-program exhibited significant improvements in their feeling; decreased anxiety, and increased pleasantness and relaxation.

Neuroticism and Negative Urgency in Problematic Alcohol Use: A Pilot Study.

PubMed

Papachristou, Harilaos; Nederkoorn, Chantal; Jansen, Anita

2016-09-18

Problematic alcohol use is common among university students and personality might account for individual differences in developing this maladaptive behavior. Two personality dispositions implicated in problematic alcohol use are negative urgency and neuroticism. However, the relationship of these traits to problematic alcohol use is unclear. In college students high neuroticism is not directly linked to problematic alcohol use. On the other hand, the experience of emotional distress in people high in neuroticism could impair the capacity for impulse control. Loss of impulse control under conditions of negative affect could trigger impulsive drinking and problematic alcohol use in the long run. We investigated this idea by testing whether negative urgency mediates the relationship of neuroticism to problematic alcohol use. Participants were 60 undergraduate university students who completed the Urgency subscale of the Urgency, (lack of) Premeditation, (lack of) Perseverance, Sensation Seeking, and Positive Urgency Impulsive Behaviour scale (UPPS-P), the Alcohol Use Disorders Identification Test (AUDIT), and the Neuroticism subscale of the Eysenck Personality Questionnaire Revised short form (EPQ-RSS). The results confirmed our hypothesis as we found an indirect effect of negative urgency on the relationship between neuroticism and problematic alcohol use. It appears that it is not distress but the tendency to act rashly when distressed that is important in developing problematic alcohol drinking in university students.

Association between insulin and executive functioning in alcohol dependence: a pilot study.

Alcohol dependence is a disorder ascribable to multiple factors and leads to cognitive impairment. Given that insulin dysregulation can cause cognitive impairment, patients with alcohol dependence are likely to develop insulin dysregulation such as that in diabetes. The purposes of this study are to identify an association between cognitive functioning and insulin and to investigate insulin as the biomarker of cognitive functioning in alcohol-dependent patients. Serum insulin levels were measured and cognitive functions were assessed in 45 patients with chronic alcoholism. The Korean version of the Consortium to Establish a Registry for Alzheimer's Disease (CERAD-K), a battery of cognitive function tests, was used to assess cognitive functioning. Serum insulin levels were not significantly correlated with most CERAD-K scores, but there was a significant negative correlation with scores on the Trail Making Test B, which is designed to measure executive functioning. Lower serum insulin levels were associated with slower executive functioning responses on the Trail Making Test B, suggesting that executive functioning may be in proportion to serum insulin levels. Thus, in patients with alcohol dependence, insulin level is associated with cognitive functioning. In addition, the present findings suggest that insulin level is a potential biomarker for determining cognitive functioning.

Digital interventions to reduce risk behaviours are emerging as effective public health measures; however, few have been applied to drink driving and associated alcohol use based on a harm reduction perspective. This paper reports on the design, development, and pilot of a novel intervention which aims to reduce repeat offending by first-time convicted drink driving offenders. It explores whether an online program is acceptable and user friendly and contains useful and relevant content, with a sample of first-time drink driving offenders recruited at the time of conviction. Building upon existing research into interventions to reduce drink driving recidivism and problem alcohol use, a tailored program was designed to provide content specifically concerned with drink driving and with an additional component related to alcohol use. Following stakeholder and internal review, the 'Steering Clear First Offender Drink Driving Program' was subsequently piloted with 15 first-time drink driving offenders. Evaluative data was analysed both quantitatively and qualitatively. The pilot results indicate that the participants found the program to be user friendly, as demonstrated by high scores in relation to navigation, online delivery, engagement, avatar usage and straightforwardness. They reported that they found the content to be useful and relevant and that the key learning area was in relation to the consequences of drink driving. Online interventions for reducing risky behaviour such as drink driving may be useful and cost effective from a public health perspective. Potentially, they can directly address risky behaviours associated with alcohol use in high-risk cohorts that may not ordinarily receive intervention.

Study design to develop and pilot-test a web intervention for partners of military service members with alcohol misuse.

Alcohol misuse among military service members from the recent conflicts in Iraq and Afghanistan is over two times higher compared to misuse in the civilian population. Unfortunately, in addition to experiencing personal consequences from alcohol misuse, partners and family members of alcohol-misusing service members also suffer in negative ways from their loved one's drinking. These family members represent important catalysts for helping their loved ones identify problem drinking and overcoming the barriers to seeking care. This paper describes the protocol to a pilot study evaluating a 4-session, web-based intervention (WBI) for concerned partners (CPs) of service members with alcohol misuse. The WBI will be adapted from the Community Reinforcement and Family Training (CRAFT) intervention. In the first phase, we will develop and beta-test the WBI with 15-20 CPs. In the second phase, we will randomize CPs to WBI (n = 50) or to delayed-WBI (n = 50) and evaluate the impact of the WBI on CPs' perceptions of service member help-seeking and drinking, as well as the CP's well-being and relationship satisfaction 3 months after the intervention. In the third phase, we will recruit 15-20 service members whose partners have completed the study. We will interview the service members to learn how the CP-focused WBI affected them and to assess whether they would be receptive to a follow-on WBI module to help them. This project has the potential to benefit a large population of military service members who may be disproportionately affected by recent conflicts and whose drinking misuse would otherwise go undetected and untreated. It also develops a new prevention model that does not rely on service members or partners attending a hospital or clinical facility to access care. NCT02073825.

Our understanding of how community-level context impacts care of persons living with HIV (PLWH), including antiretroviral therapy (ART) adherence and retention in care, is limited. The objective of this study was to characterize the activity spaces of PLWH from an urban area in Southeastern U.S., where the epidemic is among the nation's highest, and to examine how such activity spaces are associated with daily mood and health behaviors. In this small, pilot study, 11 participants were tracked with a global positioning system (GPS)-enabled application on their smartphones for 2 weeks. Activity spaces were created by connecting GPS points sequentially and adding buffers. Contextual exposure data (e.g., alcohol outlets) were connected to activity spaces. Participants also completed daily diary entry through texts 3 times per day regarding outcomes of substance use behaviors, mood, and medication adherence. This yielded a total of 18,007 GPS polyline records that we aggregated into 258 person-days that captured discrete occasions of exposure to contextual factors and subjects' behaviors and moods. On average, the participants spent 19% of their time awake during the 2-week periods in their residential census tract. Exposure to social and built environment factors such as alcohol outlets was greater when participants were outside versus inside their residential census tract. Exposures on daily routes were also significantly associated with ART adherence, alcohol consumption, and mood. Findings suggest substantial differences between activity spaces and residential contexts. Activity spaces are relevant for PLWH and may impact HIV care and behavioral outcomes such as ART adherence and substance use. Copyright © 2018 Elsevier B.V. All rights reserved.

Chronically homeless individuals with alcohol dependence experience severe alcohol-related consequences. It is therefore important to identify factors that might be associated with reduced alcohol-related harm, such as the use of safer-drinking strategies. Whereas effectiveness of safer-drinking strategies has been well-documented among young adults, no studies have explored this topic among more severely affected populations, such as chronically homeless individuals with alcohol dependence. The aims of this study were thus to qualitatively and quantitatively document safer-drinking strategies used in this population. Participants (N=31) were currently or formerly chronically homeless individuals with alcohol dependence participating in a pilot study of extended-release naltrexone and harm-reduction counseling. At weeks 0 and 8, research staff provided a list of safer-drinking strategies for participants to endorse. Implementation of endorsed safer-drinking strategies was recorded at the next appointment. At both time points, strategies to buffer the effects of alcohol on the body (e.g., eating prior to and during drinking) were most highly endorsed, followed by changing the manner in which one drinks (e.g., spacing drinks), and reducing alcohol consumption. Quantitative analyses indicated that all participants endorsed safer-drinking strategies, and nearly all strategies were implemented (80–90% at weeks 0 and 8, respectively). These preliminary findings indicate that chronically homeless people with alcohol dependence use strategies to reduce harm associated with their drinking. Larger randomized controlled trials are needed to test whether interventions that teach safer-drinking strategies may reduce overall alcohol-related harm in this population. PMID:25690515

Extant literature has established a strong relation between individual differences in "impulsivity" and alcohol consumption. However, the relation between "impulsivity," intentions-to-drink, and alcohol consumption has remained understudied. As a part of a larger study, 77 participants (60.5% female, 76.3% White, M age=20.8) completed 10days of daily diary reports regarding their intention to use alcohol and alcohol consumption. Hierarchical linear modeling (HLM) was used to estimate within-person relations between intentions-to-drink and subsequent alcohol use. All models were adjusted for participant age, biological sex, and day of the week. Results showed a strong positive association between daily intention to consume alcohol and self-reported alcohol use (β=0.50, p<0.01). Importantly, tests of interactions indicated that individuals higher in impulsivity were not significantly more likely to engage in unplanned drinking. Multilevel mediation analyses indicated significant indirect effects between impulsivity-like constructs, including positive urgency, lack-of-planning, and self-report delay discounting, and reported daily alcohol consumption via higher overall (i.e., between-person) levels of intentions-to-drink; that is, individuals who reported higher levels of these impulsivity-related constructs were more likely to intend to drink across the 10-days and, in turn, consumed more alcohol. Findings from the study suggest that treatment providers could address drinking intentions among individuals higher in impulsivity and work to establish potential replacement behaviors to reduce alcohol consumption in this population.

Mobile applications (apps) have created new opportunities in the field of alcohol dependence (AD) within new paradigms of shared decision-making and self-management. The aim of this study is to report the results of a pilot study testing the usability of and satisfaction with a mobile app (called SIDEAL) in AD patients. Adult AD outpatients were included. SIDEAL was installed on patients' personal phones. The Timeline Followback (TLFB) method for the preceding 6 weeks was administered both at baseline and after 6 weeks (end of the study). Self-reports from the app were also assessed at the end of the study and compared to data provided by the TLFB. An online questionnaire about usability and satisfaction was administered to participants after completion of the study. Exploratory efficacy analyses were conducted. Twenty-four patients were included (mean age 48 years (SD 11.3), women 50%). Most patients (22/24) selected a goal to reduce their consumption. Patients used the self-register module of the app for an average of 80% of the study days. The consumption and medication self-register modules were the most valued, as along with the weekly feedback provided by the app about participants' weekly rate of usage. Participants' satisfaction with the app was high. Significant reductions were observed in alcohol consumption (binge drinking days in the last 6 weeks declined from 25 (SD 18.6) to 5.8 (SD 8), p < 0.001; mean daily alcohol consumption in standard units declined from 6.5 (SD 4.3) to 1.9 (SD 1.8), p < 0.001). On most days (88%), patients achieved their self-imposed objectives. SIDEAL is a well-accepted and highly used app by AD patients that could improve their efficacy in managing their AD. Further larger, randomized studies are warranted.

Polydatin, a hydroxystilbene derived from the rhizome of Polygonum cuspidatum, elicits hepatoprotective and neuroprotective effects through its anti-oxidant properties. The present study aimed to determine the effects of oral administration of polydatin in alcoholic patients in order to improve liver biochemical parameters, serum oxidative stress and mental state. We enrolled 20 chronic alcoholic patients hospitalized for rehabilitative therapy. The patients were divided into two groups receiving the following treatment regimes for two weeks: administration of an anti-oxidant nutritional supplement containing glutathione and vitamin C (group 1), or glutathione, vitamin C and polydatin (group 2). The results of the present study show that elevated plasma aspartate aminotransferase and alanine aminotransferase levels in patients after two weeks of alcohol withdrawal were significantly reduced by polydatin (group 2), when compared to group 1. Polydatin also significantly reduced lipid peroxidation levels. Finally, our preliminary data resulting from the analysis of the Mini-Mental Status suggest that polydatin improves cognitive performance. Daily dietary administration of polydatin should be considered for prevention and treatment of liver disease and cognitive impairment in alcoholic patients.

This study piloted procedures and obtained data on intervention acceptability to determine the feasibility of a definitive randomised controlled trial (RCT) of the effectiveness of a computer-based brief intervention in the emergency department (ED). Two-arm, multi-site, pilot RCT. Adolescents aged 12-17 years presenting to three Canadian pediatric EDs from July 2010 to January 2013 for an alcohol-related complaint. Standard medical care plus computer-based screening and personalised assessment feedback (experimental group) or standard care plus computer-based sham (control group). ED and research staff, and adolescents were blinded to allocation. Main: change in alcohol consumption from baseline to 1- and 3 months post-intervention. Secondary: recruitment and retention rates, intervention acceptability and feasibility, perception of group allocation among ED and research staff, and change in health and social services utilisation. Of the 340 adolescents screened, 117 adolescents were eligible and 44 participated in the study (37.6% recruitment rate). Adolescents allocated to the intervention found it easy, quick and informative, but were divided on the credibility of the feedback provided (agreed it was credible: 44.4%, disagreed: 16.7%, unsure: 16.7%, no response: 22.2%). We found no evidence of a statistically significant relationship between which interventions adolescents were allocated to and which interventions staff thought they received. Alcohol consumption, and health and social services data were largely incomplete due to modest study retention rates of 47.7% and 40.9% at 1- and 3 months post-intervention, respectively. A computer-based intervention was acceptable to adolescents and delivery was feasible in the ED in terms of time to use and ease of use. However, adjustments are needed to the intervention to improve its credibility. A definitive RCT will be feasible if protocol adjustments are made to improve recruitment and retention rates; and increase the number of study sites and research staff. clinicaltrials.gov NCT01146665. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Measuring activity spaces, places adolescents spend time, provides information about relations between contextual exposures and risk behaviors. We studied whether contextual exposures in adolescents' activity spaces differ from contextual risks present in residential contexts and examined relationships between contextual exposures in activity spaces and alcohol/marijuana use. Adolescents (N = 18) aged 16-17 years carried global positioning system (GPS)-enabled smartphones for 1 week, with locations tracked. Activity spaces were created by connecting global positioning system points sequentially and adding buffers. Contextual exposure data (e.g., alcohol outlets) were connected to routes. Adolescents completed texts regarding behaviors. Adolescent activity spaces intersected 24.3 census tracts and contained nine times more alcohol outlets than that of residential census tracts. Outlet exposure in activity spaces was related to drinking. Low-socioeconomic status exposure was related to marijuana use. Findings suggest substantial differences between activity spaces and residential contexts and suggest that activity spaces are relevant for adolescent risk behaviors.

High relapse rate is one of the most prominent problems in addiction treatment. Alcohol Resilience Treatment (ART), an alcohol addiction therapy, is based on Cue Exposure Treatment, which has shown promising results in preliminary studies. ART aims at optimizing the core area of relapse prevention, and intends to improve patients' capability to withstand craving of alcohol. This method emphasizes the interplay of resilience and resourcefulness. It contains 6 sessions with different topics according to the stage of treatment circuit, and each session consists of 6 steps. Due to the purity and structure of the treatment rationale, it is realistic, reasonable and manageable to transform the method into a smartphone application. An ART app in Android system and an accessory of bilateral tactile stimulation were developed and will be used in a study with behavioral self-control training. This paper presents the design and realization of the smartphone based ART application. The design of a pilot study, which is to examine the benefits of a smartphone application providing behavioral self-control training, is also reported in this paper.

OBJECTIVE Heavy alcohol use remains a consistent public health concern on college campuses. The current pilot study used Deviance Regulation Theory (DRT) to modify Protective Behavioral Strategies (PBS) among college student drinkers to reduce alcohol use and alcohol-related consequences. METHODS The sample was comprised of current college student drinkers (n = 76; 53.95% female) ranging in age from 18-24 (M = 19.29, SD = 1.42). Participants were randomly assigned to receive a positive or negative framed message. They then reported on use of alcohol protective behavioral strategies (via the Protective Behavioral Strategies Scale), alcohol consumption (via the Modified Daily Drinking Questionnaire), and alcohol-related consequences (via the Young Adults Alcohol Consequences Questionnaire) each week for six weeks. RESULTS AND CONCLUSIONS Among drinkers with low PBS use norms, a positively, versus a negatively, framed message resulted in increased PBS use and consequently less alcohol consumption and fewer alcohol-related consequences. Among drinkers with high PBS use norms, a negatively, versus positively, framed message resulted in increased PBS use and consequently lower alcohol consumption and fewer alcohol-related consequences. However, these effects were only relevant among those who strongly believed the DRT frame. Findings suggest assigning drinkers to frames based on perceived PBS use norms and increasing belief in the frame may be one approach to increasing responsible drinking patterns among college students. Furthermore, the current data suggests important boundary conditions for norm-based interventions. PUBLIC HEALTH RELEVANCE This study of college student drinkers who received either a positive or negative framed message about reducing their drinking found that a Deviance Regulation intervention might be effective at increasing responsible alcohol use, but only among students with a high acceptance of the intervention materials.

Normative feedback for parents of college students: piloting a parent based intervention to correct misperceptions of students' alcohol use and other parents' approval of drinking.

Multi-component parent-based interventions (PBIs) provide a promising avenue for targeting alcohol use and related consequences in college students. Parents of college-aged children can have a significant influence on their children's alcohol use decisions. However, parents tend to underestimate their own child's alcohol use and overestimate other similar parents' approval of student drinking. These misperceptions could have important implications for parents' own attitudes and alcohol-related communication with their student. Targeting these misperceptions through normative feedback could help promote greater and more in-depth alcohol-related communication. The present study examines the potential efficacy of web-based alcohol-related normative feedback for parents of college students. A sample of 144 parents of college students received web-based normative feedback about students' alcohol use and approval, as well as other same-college parents' alcohol approval. Parents completed measures of perceived student alcohol use, student alcohol approval, other-parent alcohol approval, and intentions to discuss alcohol use both pre- and post-normative feedback. Post-feedback, parents reported stronger intentions to talk to their student about alcohol, were less confident in their knowledge of their students' alcohol use, and believed that their student drank in greater quantity and more frequently than pre-feedback. Parents also perceived other parents to be less approving of alcohol use after viewing normative feedback. These findings provide preliminary support for the use of web-based normative feedback for parents of college students. Given these promising results, further research developing and testing this approach merits attention. © 2013.

Effects of varenicline on operant self-administration of alcohol and/or nicotine in a rat model of co-abuse.

Funk, D; Lo, S; Coen, K; Lê, A D

Alcohol and nicotine (in the form of tobacco) are often taken together, with increased negative health consequences. Co-use may modify intake of one or both of the drugs, or the effects of drugs used to treat nicotine or alcohol addiction. Varenicline is commonly prescribed as an aid to enhance quitting smoking. More recently it has been shown to reduce alcohol intake in humans and laboratory animals. There is little work investigating the role of co-exposure to alcohol and nicotine in the effects of varenicline. In pilot clinical studies, it has been reported that smoking enhances varenicline's effectiveness as a treatment for alcohol misuse, but this relationship has not been systematically investigated. To help resolve this, we examined if the effects of varenicline on alcohol and nicotine self-administration (SA) in rats are modified when the two drugs are taken together. Rats were trained on alcohol SA, and some were implanted with i.v. catheters for nicotine SA. Groups of animals then lever pressed for alcohol or nicotine alone, and another group lever pressed for alcohol and nicotine, using a two lever choice procedure. Varenicline did not affect alcohol SA. Varenicline reduced nicotine SA modestly. Access to both alcohol and nicotine reduced self-administration of either drug, but did not change the effects of varenicline. We found that in rats with a history of alcohol SA, varenicline reduced reinstatement of extinguished alcohol seeking induced by exposure to an alcohol prime combined with cues previously associated with alcohol.

The aim of this Stage I Behavioral Development Trial was to develop a manual-based 12-session Women's Recovery Group (WRG) and to pilot test this new treatment in a randomized controlled trial against a mixed-gender Group Drug Counseling (GDC), an effective manual-based treatment for substance use disorders. After initial manual development, two pre-pilot groups of WRG were conducted to determine feasibility and initial acceptability of the treatment among subjects and therapists. In the pilot stage, women were randomized to either WRG or GDC. No significant differences in substance use outcomes were found between WRG and GDC during the 12-week group treatment. However, during the 6-month post-treatment follow-up, WRG members demonstrated a pattern of continued reductions in substance use while GDC women did not. In addition, pilot WRG women with alcohol dependence had significantly greater reductions in average drinks/drinking day than GDC women 6 months post-treatment (p<.03, effect size=0.81). While satisfaction with both groups was high, women were significantly more satisfied with WRG than GDC (p<.009, effect size=1.11). In this study, the newly developed 12-session women-focused WRG was feasible with high satisfaction among participants. It was equally effective as mixed-gender GDC in reducing substance use during the 12-week in-treatment phase, but demonstrated significantly greater improvement in reductions in drug and alcohol use over the post-treatment follow-up phase compared with GDC. A women-focused single-gender group treatment may enhance longer-term clinical outcomes among women with substance use disorders.

Objectives To describe the development and test–retest reliability of OHCITIES, an instrument characterising alcohol urban environment in terms of availability, promotion and signs of consumption. Design This study involved: (1) developing the conceptual framework for alcohol urban environment by means of literature reviewing and previous alcohol environment research experience; (2) pilot testing and redesigning the instrument; (3) instrument digitalisation; (4) instrument evaluation using test–retest reliability. Setting Data for testing the reliability of the instrument were collected in seven census sections in Madrid in 2016 by two observers. Primary and secondary outcome measures We computed per cent agreement and Cohen’s kappa coefficients to estimate inter-rater and test–retest reliability for alcohol outlet environment measures. We calculated interclass coefficients and their 95% CIs to provide a measure of inter-rater reliability for signs of alcohol consumption measures. Results We collected information on 92 on-premise and 24 off-premise alcohol outlets identified in the studied areas about availability, accessibility and promotion of alcohol. Most per cent-agreement values for alcohol measures in on-premise and off-premise alcohol outlets were greater than 80%, and inter-rater and test–retest reliability values were generally above 0.80. Observers identified 26 streets and 3 public squares with signs of alcohol consumption. Intraclass correlation coefficient between observers for any type of signs of alcohol consumption was 0.50 (95% CI −0.09 to 0.77). Few items promoting alcohol unrelated to alcohol outlets were found on public spaces. Conclusions The OHCITIES instrument is a reliable instrument to characterise alcohol urban environment. This instrument might be used to understand how alcohol environment associates with alcohol behaviours and its related health outcomes, and can help in the design and evaluation of policies to reduce the harm caused by alcohol.

This pilot study examined the relationship between smoking, alcohol intake, depressive symptoms and quality of life (QoL) in head and neck cancer patients. A questionnaire on smoking, alcohol, depressive symptoms and QoL was distributed to head and neck cancer patients (N=81). Over one-third (35%) of the respondents had smoked within the last 6 months, 46% had drunk alcohol within the last 6 months and 44% screened positive for significant depressive symptoms. About one-third (32%) of smokers were interested in smoking cessation services and 37% of patients with depressive symptoms were interested in depression services. However, only 9% of those who drank alcohol expressed interest in alcohol services. Smoking was negatively associated with five scales of the SF-36V including Physical Functioning, General Health, Vitality, Social Functioning, and Role-Emotional Health. Depressive symptoms were negatively associated with all eight scales on the SF-36V and all four scales of the Head and Neck Quality of Life instrument. Surprisingly, alcohol was not found to be associated with any of the QoL scales. While smoking, alcohol intake and depression may be episodically treated, standardized protocols and aggressive intervention strategies for systematically addressing these highly prevalent disorders are needed in this population.

2008-01-01

Heavy drinking young adults often have limited motivation to change their drinking behavior. Adding pharmacotherapy to brief counseling is a novel approach to treating this population. A small open-label pilot study was conducted to assess the feasibility of offering eight weeks of daily and targeted (i.e., taken as needed in anticipation of drinking) naltrexone with BASICS (brief motivational) counseling to heavy drinking young adults; to assess the tolerability of the medication in this population and to obtain preliminary efficacy data. The sample (N = 14) showed strong adherence to study appointments and medication taking, supporting the feasibility of this approach. Overall, the medication was well-tolerated. Significant reductions from baseline were observed in drinks per drinking day and in percent heavy drinking days and these gains were maintained one month after treatment ended. A significant decrease in alcohol-related consequences was also observed. Findings from this small pilot study suggest that naltrexone in combination with BASICS represents a promising strategy to reduce heavy drinking among young adults. PMID:18502591

Western Australian Public Opinions of a Minimum Pricing Policy for Alcohol: Study Protocol

Keatley, David A; Daube, Mike; Hardcastle, Sarah J

2015-01-01

Background Excessive alcohol consumption has significant adverse economic, social, and health outcomes. Recent estimates suggest that the annual economic costs of alcohol in Australia are up to AUD $36 billion. Policies influencing price have been demonstrated to be very effective in reducing alcohol consumption and alcohol-related harms. Interest in minimum pricing has gained traction in recent years. However, there has been little research investigating the level of support for the public interest case of minimum pricing in Australia. Objective This article describes protocol for a study exploring Western Australian (WA) public knowledge, understanding, and reaction to a proposed minimum price policy per standard drink. Methods The study will employ a qualitative methodological design. Participants will be recruited from a wide variety of backgrounds, including ethnic minorities, blue and white collar workers, unemployed, students, and elderly/retired populations to participate in focus groups. Focus group participants will be asked about their knowledge of, and initial reactions to, the proposed policy and encouraged to discuss how such a proposal may affect their own alcohol use and alcohol consumption at the population level. Participants will also be asked to discuss potential avenues for increasing acceptability of the policy. The focus groups will adopt a semi-structured, open-ended approach guided by a question schedule. The schedule will be based on feedback from pilot samples, previous research, and a steering group comprising experts in alcohol policy and pricing. Results The study is expected to take approximately 14 months to complete. Conclusions The findings will be of considerable interest and relevance to government officials, policy makers, researchers, advocacy groups, alcohol retail and licensed establishments and organizations, city and town planners, police, and other stakeholder organizations.

Background Alcohol use, and in particular, binge drinking, and methamphetamine use is pervasive among homeless youth and remains a social pressure among this vulnerable population. However, there is no compelling evidence that specific interventions for reducing drug and alcohol use are effective for homeless youth. Objectives This community-based participatory action pilot study assessed the impact of an intervention study focused on decreasing use of drugs and alcohol among a sample of homeless young adults (N=154) visiting a drop-in site in Santa Monica, California. The two programs consisted of a HIV/AIDS and Hepatitis Health Promotion (HHP) program led by nurses and an Art Messaging (AM) program led by artists. Six-month follow-up data were obtained from 100 of these individuals. Results Findings revealed significant reductions in alcohol and marijuana use and binge drinking in both the HHP and AM programs. However, homeless youth in the HHP program reported additional reductions in methamphetamine, cocaine and hallucinogen use at six-month follow-up. Conclusions Reductions in drugs and alcohol are important as these substances are linked to HIV/AIDS, hepatitis and other health risks in homeless youth. Scientific Significance The successful outcomes of the study intervention validate the utility of nurse-led and artistic health promotion strategies to decrease drug and alcohol use and other risky behaviors in homeless youth populations.

Worldwide, 16% of people aged 15 and older engage in harmful use of alcohol. Harmful alcohol use leads to a host of preventable negative social and health consequences. Mobile technology-based interventions provide a particularly promising avenue for the widespread and cost-effective delivery of treatment that is accessible, affordable, individualized, and destigmatized to both alcohol-dependent and nondependent individuals. The present review sought to summarize the current literature on mobile technology-based interventions among adult users of alcohol and determine the efficacy of such interventions. Five databases were searched in December 2015 (Jan. 2004-Dec. 2015). Inclusion criteria were: participants aged 18 or older, interventions delivered through mobile-technology, and outcome measurement of alcohol reduction/cessation. Eight studies met inclusion criteria. The majority of the studies reviewed found positive effects of the intervention, even though the interventions themselves varied in design, length, dosage, and target population, and were pilot or preliminary in nature. Findings from this review highlight the promising, yet preliminary state of research in this area. Studies with adequate power and valid design are necessary to evaluate the potential of mobile technology-based interventions on long-term alcohol behavior outcomes. Furthermore, future research should elucidate what the most effective length of time is for a mobile technology-based intervention, how often individuals should receive messages for maximum benefit, and determine the comparative effectiveness of mobile technology interventions with other efficacious interventions.

Fermentation of syngas offers several advantages compared to chemical catalysts such as higher specificity of biocatalysts, lower energy costs, and higher carbon efficiency. Scale-up of syngas fermentation from a bench scale to a pilot scale fermentor is a critical step leading to commercialization. The primary objective of this research was to install and commission a pilot scale fermentor, and subsequently scale-up the Clostridium strain P11 fermentation from a 7.5-L fermentor to a pilot scale 100-L fermentor. Initial preparation and fermentations were conducted in strictly anaerobic conditions. The fermentation system was maintained in a batch mode with continuous syngas supply. The effect of anaerobic fermentation in a pilot scale fermentor was evaluated. In addition, the impact of improving the syngas mass transfer coefficient on the utilization and product formation was studied. Results indicate a six fold improvement in ethanol concentration compared to serum bottle fermentation, and formation of other compounds such as isopropyl alcohol, acetic acid and butanol, which are of commercial importance.

Most treatment programs for alcohol dependence have prioritized alcohol abstinence as the primary treatment goal. However, abstinence-based goals are not always considered desirable or attainable by more severely affected populations, such as chronically homeless people with alcohol dependence. Because these individuals comprise a multimorbid and high-utilizing population, they are in need of more focused research attention that elucidates their preferred treatment goals. The aim of this secondary study was therefore to qualitatively and quantitatively document participant-generated treatment goals. Participants were currently or formerly chronically homeless individuals (N=31) with alcohol dependence who participated in a pilot of extended-release naltrexone and harm-reduction counseling. Throughout the treatment period, study interventionists elicited participants’ goals and recorded them on an open-ended grid. In subsequent weeks, progress towards and achievement of goals was obtained via self-report and recorded by study interventionists. Conventional content analysis was performed to classify participant-generated treatment goals. Representation of the three top categories remained stable over the course of treatment. In the order of their frequency, they included drinking-related goals, quality-of-life goals and health-related goals. Within the category of drinking-related goals, participants consistently endorsed reducing drinking and alcohol-related consequences ahead of abstinence-based goals. Quantitative analyses indicated participants generated an increasing number of goals over the course of treatment. Proportions of goals achieved and progressed toward kept pace with this increase. Findings confirmed hypotheses that chronically homeless people with alcohol dependence can independently generate and achieve treatment goals toward alcohol harm reduction and quality-of-life improvement.

Closed circuit television (CCTV) systems which incorporate real-time communication links between camera room operators and on-the-ground security may limit injuries resulting from alcohol-related assault. This pilot study examined CCTV footage and operator records of security responses for two periods totalling 22 days in 2010-2011 when 30 alcohol-related assaults were recorded. Semistructured discussions were conducted with camera room operators during 18 h of observation. Camera operators were proactive, efficiently directing street security to assault incidents. The system intervened in 40% (n=12) of alcohol-related assaults, limiting possible injury. This included three incidents judged as potentially preventable. A further five (17%) assault incidents were also judged as potentially preventable, while 43% (n=13) happened too quickly for intervention. Case studies describe security intervention in each category. Further research is recommended, particularly to evaluate the effects on preventing injuries through targeted awareness training to improve responsiveness and enhance the preventative capacity of similar CCTV systems.

Relationship between a GABAA alpha 6 Pro385Ser substitution and benzodiazepine sensitivity.

In humans, interindividual variation in sensitivity to benzodiazepine drugs may correlate with behavioral variation, including vulnerability to disease states such as alcoholism. In the rat, variation in alcohol and benzodiazepine sensitivity has been correlated with an inherited variant of the GABAA alpha 6 receptor. The authors detected a Pro385Ser [1236C > T] amino acid substitution in the human GABAA alpha 6 that may influence alcohol sensitivity. In this pilot study, they evaluated the contribution of this polymorphism to benzodiazepine sensitivity. Sensitivity to diazepam was assessed in 51 children of alcoholics by using two eye movement measures: peak saccadic velocity and average smooth pursuit gain. Association analysis was performed with saccadic velocity and smooth pursuit gain as dependent variables and comparing Pro385/Ser385 heterozygotes and Pro385/Pro385 homozygotes. The Pro385Ser genotype was associated with less diazepam-induced impairment of saccadic velocity but not with smooth pursuit gain. The Pro385Ser genotype may play a role in benzodiazepine sensitivity and conditions, such as alcoholism, that may be correlated with this trait.

Objective Multi-component parent-based interventions (PBIs) provide a promising avenue for targeting alcohol use and related consequences in college students. Parents of college-aged children can have a significant influence on their children’s alcohol use decisions. However, parents tend to underestimate their own child’s alcohol use and overestimate other similar parents’ approval of student drinking. These misperceptions could have important implications for parents’ own attitudes and alcohol-related communication with their student. Targeting these misperceptions through normative feedback could help promote greater and more in-depth alcohol-related communication. The present study examines the potential efficacy of web-based alcohol-related normative feedback for parents of college students. Method A sample of 144 parents of college students received web-based normative feedback about students’ alcohol use and approval, as well as other same-college parents’ alcohol approval. Parents completed measures of perceived student alcohol use, student alcohol approval, other-parent alcohol approval, and intentions to discuss alcohol use both pre- and post-normative feedback. Results Post-feedback, parents reported stronger intentions to talk to their student about alcohol, were less confident in their knowledge of their students’ alcohol use, and believed that their student drank in greater quantity and more frequently than pre-feedback. Parents also perceived other parents to be less approving of alcohol use after viewing normative feedback. Conclusions These findings provide preliminary support for the use of web-based normative feedback for parents of college students. Given these promising results, further research developing and testing this approach merits attention. PMID:24099892

The US Department of Transportation (DOT) regulates on-the-job alcohol use by operators of certain categories of commercial transport. For aircraft, trains, and commercial vessels, operators are subject to sanctions for having > or = 0.04 g% blood alcohol concentration (BAC). This study examines the effects of alcohol (between 0.04 and 0.05 g% BAC) on simulated merchant ship handling. A two-group randomized factorial design was used to compare beverage alcohol to placebo while controlling for baseline performance on a previous day. The study was conducted in the Maritime Simulation Center at Maine Maritime Academy, Castine, ME. Participants were 38 volunteer deck officer cadets in their junior or senior year, at least 21 years of age, with previous experience on a bridge simulator. Following a baseline trial on Day 1, on Day 2 participants were randomized to receive alcohol (0.6 g/kg for males and 0.5 g/kg for females) or placebo. After allowing time for absorption, participants completed a bridge simulator task. For baseline and performance trials, participants were randomized to one of four bridge simulator scenarios, each representing passage of a fully loaded container vessel through a channel with commercial traffic. The aggregate scenario score given by blinded maritime educators measured performance. A main effect for alcohol was found indicating that performance was significantly impaired by this low dose of alcohol relative to performance in the placebo condition. These findings are consistent with current federal regulations that limit low-dose alcohol exposure for the operators of commercial transport vehicles. Further research is required to determine effects at lower BACs.

Objectives The online universal Climate Schools intervention has been found to be effective in reducing the use of alcohol and cannabis among Australian adolescents. The aim of the current study was to examine the feasibility of implementing this prevention programme in the UK. Design A pilot study examining the feasibility of the Climate Schools programme in the UK was conducted with teachers and students from Year 9 classes at two secondary schools in southeast London. Teachers were asked to implement the evidence-based Climate Schools programme over the school year with their students. The intervention consisted of two modules (each with six lessons) delivered approximately 6 months apart. Following completion of the intervention, students and teachers were asked to evaluate the programme. Results 11 teachers and 222 students from two secondary schools evaluated the programme. Overall, the evaluations were extremely positive. Specifically, 85% of students said the information on alcohol and cannabis and how to stay safe was easy to understand, 84% said it was easy to learn and 80% said the online cartoon-based format was an enjoyable way to learn health theory topics. All teachers said the students were able to recall the information taught, 82% said the computer component was easy to implement and all teachers said the teacher's manual was easy to use to prepare class activities. Importantly, 82% of teachers said it was likely that they would use the programme in the future and recommend it to others. Conclusions The Internet-based universal Climate Schools prevention programme to be both feasible and acceptable to students and teachers in the UK. A full evaluation trial of the intervention is now required to examine its effectiveness in reducing alcohol and cannabis use among adolescents in the UK before implementation in the UK school system.

Continued high alcohol consumption levels by college students highlight the need for more effective alcohol interventions and novel treatment engagement strategies. The purpose of this study was to investigate a behavioral sleep intervention as a means to engage heavy-drinking college students in treatment and reduce alcohol use and alcohol-related consequences. Heavy-drinking college students (N = 42) were assigned to 1 of 2 web-based interventions comprised of 4 modules delivered over 4 weeks. The experimental intervention focused primarily on sleep and included evidence-based sleep content (i.e., stimulus control instructions, sleep scheduling [consistent bed/rise times; ideal sleep duration for adolescents/young adults], sleep hygiene advice, relaxation training, cognitive strategies to target sleep-disruptive beliefs), and alcohol content (i.e., normative and blood alcohol level feedback, moderate drinking guidelines, controlled drinking strategies, effects of alcohol on sleep and the body, advice to moderate drinking for improved sleep) in young adults. The control condition Healthy Behaviors provided basic advice about nutrition, exercise, sleep (i.e., good sleep hygiene only), and drinking (i.e., effects of alcohol on the body, moderate drinking guidelines, advice to moderate drinking for sleep). Participants in both conditions monitored their sleep using daily web-based diaries and a wrist-worn sleep tracker. Recruitment ads targeting college students with sleep concerns effectively identified heavy-drinking students. The program generated a high number of inquiries and treatment completion rates were high. Both interventions significantly reduced typical week drinking and alcohol-related consequences and improved sleep quality and sleep-related impairment ratings. The control condition yielded greater reductions in total drinks in a heaviest drinking week. The effects on drinking were larger than those observed in typical brief alcohol intervention studies for college students. Greater sleep improvement tended to predict better subsequent drinking outcomes. The results suggest that sleep treatment may be a promising strategy for targeting and treating heavy-drinking college students. Copyright © 2017 by the Research Society on Alcoholism.

2016-04-30

Association Splitting, a novel cognitive intervention, was tested in patients with alcohol dependence as an add-on intervention in an initial randomized controlled trial. Preliminary support for Association Splitting has been found in patients with obsessive-compulsive disorder, as well as in an online pilot study of patients with alcohol use disorders. The present variant sought to reduce craving by strengthening neutral associations with alcohol-related stimuli, thus, altering cognitive networks. Eighty-four inpatients with verified diagnoses of alcohol dependence, who were currently undergoing inpatient treatment, were randomly assigned to Association Splitting or Exercise Therapy. Craving was measured at baseline, 4-week follow-up, and six months later with the Obsessive-Compulsive Drinking Scale (primary outcome) and the Alcohol Craving Questionnaire. There was no advantage for Association Splitting after three treatment sessions relative to Exercise Therapy. Among Association Splitting participants, 51.9% endorsed a subjective decline in craving and 88.9% indicated that they would use Association Splitting in the future. Despite high acceptance, an additional benefit of Association Splitting beyond standard inpatient treatment was not found. Given that participants were concurrently undergoing inpatient treatment and Association Splitting has previously shown moderate effects, modification of the study design may improve the potential to detect significant effects in future trials.

Emergency Departments (EDs) care for thousands of alcohol-intoxicated patients annually. No clinically relevant bedside measures currently exist to describe degree of impairment. To assess a group of bedside tests ("Hack's Impairment Index [HII] score") that applies a numerical value to the degree of alcohol-induced impairment in ED patients. A six-month retrospective review of HII score data was performed in a convenience sample of 293 intoxicated ED patients. Patients were scored 0-4 on five tasks, divided by the maximum score (20 if all tasks completed), every 2 hours; and classified by the number of visits: Low-frequency (1 visit); Medium-frequency (2 visits); High-frequency (≥3 visits). Correlations were assessed between HII score, healthcare provider judgment of intoxication, and measured alcohol levels. Study patients had 513 visits; 236 were low-frequency, 26 middle-frequency and 31 high-frequency. Clinical assessment and HII score were strongly correlated (Spearman's rho = 0.82, p < 0.001); clinical assessment and alcohol level less strongly so (rho = 0.49, p < 0.001). Among low-frequency patients, HII score and alcohol level were weakly correlated (r = 0.324, p < 0.001), with no such correlation among high-frequency visitors (r = -0.04, p = 0.89). The mean decline between serial HII scores was 0.126 (95% CI: 0.098-0.154). This pilot study shows the HII score can be performed at the bedside of alcohol-intoxicated patients. The HII declines in a reasonably predictable manner over time; and applies a quantitative, objective assessment of alcohol impairment.

Given the importance of developmental transitions on young adults' lives and the high rates of mental health issues among U.S. college students, first-year college students can be particularly vulnerable to stress and adversity. This pilot study evaluated the effectiveness and feasibility of mindfulness training aiming to promote first-year college students' health and wellbeing. 109 freshmen were recruited from residential halls (50% Caucasian, 66% female). Data collection was completed in November 2014. A randomized control trial was conducted utilizing the Learning to BREATHE (L2B) program, a universal mindfulness program adapted to match the developmental tasks of college transition. Participation in the pilot intervention was associated with significant increase in students' life satisfaction, and significant decrease in depression and anxiety. Marginally significant decrease was found for sleep issues and alcohol consequences. Mindfulness-based programs may be an effective strategy to enhance a healthy transition into college.

2009-01-01

Significant involvement of students in the development and implementation of college alcohol prevention strategies is largely untested, despite recommendations by the National Institute of Alcohol Abuse and Alcoholism and others. The purpose of the Pragmatics Project was to test a student engagement model for developing and implementing alcohol intervention strategies. The Pragmatics Project involved 89 undergraduate students on a large Midwestern university campus in the design and implementation of projects focused on reducing harm associated with high-risk drinking and off-campus parties. The engagement model used an innovative course piloted in the Human Development and Family Science department. The course successfully involved both students and the community in addressing local alcohol issues. The course design described would fit well into a Master of Public Health, Community Psychology, Health Psychology, or interdisciplinary curricula as well as the service learning model, and it is applicable in addressing other health risk behaviors.

Staying safe while consuming alcohol: a qualitative study of the protective strategies and informational needs of college freshmen.

Howard, Donna Elise; Griffin, Melinda; Boekeloo, Bradley; Lake, Kristin; Bellows, Denise

2007-01-01

In this qualitative study, the authors examined how students attempt to minimize harm to themselves and others when drinking. The authors recruited freshmen at a large, mid-Atlantic US public university during the fall semester of 2005 to participate in 8 focus groups. The moderator's guide was developed through an iterative process that included input from experts and pilot testing. The researchers audiotaped focus group conversations, transcribed them, and subjected them to an interrater reliability check. Analysis was based on the framework of Information-Motivation-Behavioral Skills Model and a phenomenological approach. College students have a repertoire of coping strategies they use in an attempt to safeguard themselves and their friends from harm when drinking. Strategies encompass planning a safe context for drinking, using safety measures to minimize harm when drinking, and taking care of someone who has consumed too much alcohol. A harm-reduction focus that acknowledges and builds on existing protective strategies may be a promising avenue for alcohol interventions.

Text messaging for addiction: a review.

Keoleian, Victoria; Polcin, Douglas; Galloway, Gantt P

2015-01-01

Individuals seeking treatment for addiction often experience barriers due to cost, lack of local treatment resources, or either school or work schedule conflicts. Text-messaging-based addiction treatment is inexpensive and has the potential to be widely accessible in real time. We conducted a comprehensive literature review identifying 11 published, randomized controlled trials (RCTs) evaluating text-messaging-based interventions for tobacco smoking, four studies for reducing alcohol consumption, one pilot study in former methamphetamine (MA) users, and one study based on qualitative interviews with cannabis users. Abstinence outcome results in RCTs of smokers willing to make a quit attempt have been positive overall in the short term and as far out as at six and 12 months. Studies aimed at reducing alcohol consumption have been promising. More data are needed to evaluate the feasibility, acceptability, and efficacy of this approach for other substance use problems.

2008-01-01

Alcoholic patients in inpatient detoxification were randomized to treatment as usual (TAU) or to a brief family treatment (BFT) intervention to promote continuing care post-detox. BFT consisted of meeting with the patient and an adult family member (in person or over the phone) with whom the patient lived, to review and recommend potential continuing care plans for the patient. Results showed that BFT patients (N=24), were significantly more likely than TAU patients (N=21), to enter a continuing care program after detoxification. This was a medium to large effect size. In the 3 months after detoxification, days using alcohol or drugs (a) trended lower for treatment-exposed BFT patients who had an in-person family meeting than TAU counterparts (medium effect), and (b) were significantly lower for patients who entered continuing care regardless of treatment condition (large effect).

Strategies for production of wines containing lower alcohol concentrations are in strong demand, for reasons of quality, health, and taxation. Development and application of wine yeasts that are less efficient at transforming grape sugars into ethanol has the potential to allow winemakers the freedom to make lower alcohol wines from grapes harvested at optimal ripeness, without the need for post-fermentation processes aimed at removing ethanol. We have recently shown that two non-conventional wine yeast species Metschnikowia pulcherrima and Saccharomyces uvarum were both able to produce wine with reduced alcohol concentration. Both species produced laboratory-scale wines with markedly different volatile aroma compound composition relative to Saccharomyces cerevisiae. This work describes the volatile composition and sensory profiles of reduced-alcohol pilot-scale Merlot wines produced with M. pulcherrima and S. uvarum. Wines fermented with M. pulcherrima contained 1.0% v/v less ethanol than S. cerevisiae fermented wines, while those fermented with S. uvarum showed a 1.7% v/v reduction in ethanol. Compared to S. cerevisiae ferments, wines produced with M. pulcherrima showed higher concentrations of ethyl acetate, total esters, total higher alcohols and total sulfur compounds, while wines fermented with S. uvarum were characterised by the highest total concentration of higher alcohols. Sensorially, M. pulcherrima wines received relatively high scores for sensory descriptors such as red fruit and fruit flavour and overall exhibited a sensory profile similar to that of wine made with S. cerevisiae, whereas the main sensory descriptors associated with wines fermented with S. uvarum were barnyard and meat. This work demonstrates the successful application of M. pulcherrima AWRI3050 for the production of pilot-scale red wines with reduced alcohol concentration and highlights the need for rigorous evaluation of non-conventional yeasts with regard to their sensory impacts.

Individuals with posttraumatic stress disorder (PTSD) often exhibit high-risk substance use behaviors. Complementary and alternative therapies are increasingly used for mental health disorders, although evidence is sparse. Investigate the effect of a yoga intervention on alcohol and drug abuse behaviors in women with PTSD. Secondary outcomes include changes in PTSD symptom perception and management and initiation of evidence-based therapies. The current investigation analyzed data from a pilot randomized controlled trial comparing a 12-session yoga intervention with an assessment control for women age 18 to 65 years with PTSD. The Alcohol Use Disorder Identification Test (AUDIT) and Drug Use Disorder Identification Test (DUDIT) were administered at baseline, after the intervention, and a 1-month follow-up. Linear mixed models were used to test the significance of the change in AUDIT and DUDIT scores over time. Treatment-seeking questions were compared by using Fisher exact tests. The mean AUDIT and DUDIT scores decreased in the yoga group; in the control group, mean AUDIT score increased while mean DUDIT score remained stable. In the linear mixed models, the change in AUDIT and DUDIT scores over time did not differ significantly by group. Most yoga group participants reported a reduction in symptoms and improved symptom management. All participants expressed interest in psychotherapy for PTSD, although only two participants, both in the yoga group, initiated therapy. Results from this pilot study suggest that a specialized yoga therapy may play a role in attenuating the symptoms of PTSD, reducing risk of alcohol and drug use, and promoting interest in evidence-based psychotherapy. Further research is needed to confirm and evaluate the strength of these effects.

Preventing alcohol-exposed pregnancies (AEPs) could reduce the incidence of fetal alcohol spectrum disorders. Previous face-to-face interventions significantly reduced risk for AEP, but a scalable intervention is needed to reach more women at risk. This study compared a 6 Core automated, interactive, and tailored Internet intervention, the Contraception and Alcohol Risk Reduction Internet Intervention (CARRII), to a static patient education (PE) website for its effect on AEP risk. Participants were recruited online to a pilot randomized clinical trial (RCT) with baseline, 9 weeks posttreatment, and 6-month (6-M) follow-up assessments. Seventy-one women completed online questionnaires and telephone interviews and were randomized to CARRII (n = 36) or PE (n = 35). Primary outcomes were rates of risky drinking, unprotected sex episodes, and AEP risk, collected from online prospective diaries. CARRII participants showed significant reductions in rate of unprotected sex from pretreatment (88.9%) to posttreatment (70.6%) (p < 0.04) and to 6-M follow-up (51.5%) (p = 0.001); rate of risky drinking from pretreatment (75.0%) to posttreatment (50.0%) (p < 0.02), but insignificant change from pretreatment to 6-M follow-up (57.6%) (p < 0.09); and rate of AEP risk from pretreatment (66.7%) to posttreatment (32.4%) (p = 0.001) and to 6-M follow-up (30.3%) (p = 0.005). PE participants demonstrated no significant changes on all 3 variables across all time points. Intent-to-treat group-by-time tests were not significant, but power was limited by missing diaries. Over 72% of CARRII participants completed all 6 Cores. Exploratory analyses suggest that higher program utilization is related to change. These data show that CARRII was acceptable, feasible, promising to reduce AEP risk, and merits further testing in a fully powered RCT. Copyright © 2018 by the Research Society on Alcoholism.

Abstract Background: This study presents results from qualitative interviews conducted with participants in a study on the effectiveness of the Location-Based Monitoring and Intervention System for Alcohol Use Disorders (LBMI-A), a smartphone-based, stand-alone intervention application (app) for adults with alcohol use disorders. Materials and Methods: Participants were provided an LBMI-A-enabled smartphone to use during a 6-week pilot study. The LBMI-A was composed of psychoeducational modules, assessment and feedback of alcohol use patterns, geographic high-risk location monitoring and alerts, and in vivo assessment and intervention for alcohol cravings and help with managing psychological distress. Semistructured interviews were conducted with all participants following 6 weeks of interacting with the LBMI-A app (n=26). Interviews explored user perceptions of the ease and utility of LBMI-A features, module helpfulness, barriers to use, and recommendations for improvements to the program. Researchers applied a systematic qualitative coding process to transcripts that included both a priori themes identified as important by the research team and new themes that emerged during the coding process. Results and Conclusions: Narrative analysis found the emergence of five main themes identified by LBMI-A users as the most helpful functions of the phone: (1) Awareness, (2) Accountability, (3) Skill Transference, (4) Tracking Progress, and (5) Prompts. These themes are explored, and implications of these findings for future smartphone-based interventions are discussed. PMID:25243480

We sought to examine the efficacy and safety of acamprosate augmentation of escitalopram in patients with concurrent major depressive disorder (MDD) and alcohol use disorders. Twenty-three adults (43% female; mean ± SD age, 46 ± 14 years) were enrolled and received 12 weeks of treatment with psychosocial support; escitalopram, 10 to 30 mg/d; and either acamprosate, 2000 mg/d (n = 12), or identical placebo (n = 11). Outcomes included change in clinician ratings of depressive symptoms, MDD response and remission rates, changes in frequency and intensity of alcohol use, retention rates, and adverse events. Twelve subjects (acamprosate, n = 7; placebo, n = 5) completed the study. There was significant mean reduction in ratings of depressive symptoms from baseline in both treatment arms (P < 0.05), with no significant difference between the groups. Those in the acamprosate group had a 50% MDD response rate and a 42% remission rate, whereas those in the placebo arm had a 36% response and remission rate (not significant). Those assigned to acamprosate had significant reduction in number of drinks per week and drinks per month during the trial, whereas those assigned to placebo demonstrated no significant change in any alcohol use parameter, but the between-group difference was not significant. There were no significant associations between change in depressive symptoms and change in alcohol use. Attrition rates did not differ significantly between the 2 arms. Acamprosate added to escitalopram in adults with MDD and alcohol use disorders was associated with reduction in the frequency of alcohol use. The present study was not powered to detect superiority versus placebo. Further study in a larger sample is warranted. PMID:23131884

Background Continued high alcohol consumption levels by college students highlight the need for more effective alcohol interventions and novel treatment engagement strategies. The purpose of this study was to investigate a behavioral sleep intervention as a means to engage heavy-drinking college students in treatment and reduce alcohol use and alcohol-related consequences. Methods Heavy-drinking college students (N=42) were assigned to 1 of 2 web-based interventions comprised of 4 modules delivered over 4 weeks. The experimental intervention focused primarily on sleep and included evidence-based sleep content (i.e., stimulus control instructions, sleep scheduling (consistent bed/rise times; ideal sleep duration for adolescents/young adults), sleep hygiene advice, relaxation training, cognitive strategies to target sleep-disruptive beliefs) and alcohol content (i.e., normative and blood alcohol level feedback, moderate drinking guidelines, controlled drinking strategies, effects of alcohol on sleep and the body, advice to moderate drinking for improved sleep) in young adults. The healthy behaviors control condition provided basic advice about nutrition, exercise, sleep (i.e., good sleep hygiene only) and drinking (i.e., effects of alcohol on the body, moderate drinking guidelines, advice to moderate drinking for sleep). Participants in both conditions monitored their sleep using daily web-based diaries and a wrist-worn sleep tracker. Results Recruitment ads targeting college students with sleep concerns effectively identified heavy-drinking students. The program generated a high number of inquiries and treatment completion rates were high. Both interventions significantly reduced typical week drinking and alcohol-related consequences and improved sleep quality and sleep-related impairment ratings. The control condition yielded greater reductions in total drinks in a heaviest drinking week. The effects on drinking were larger than those observed in typical brief alcohol intervention studies for college students. Greater sleep improvement tended to predict better subsequent drinking outcomes. The results suggest that sleep treatment may be a promising strategy for targeting and treating heavy-drinking college students. PMID:28118486

PTSD and substance use disorder (SUD) are highly prevalent among Veterans returning from Iraq and Afghanistan (Operation Enduring Freedom/Operation Iraqi Freedom; OEF/OIF). Seeking Safety (SS) is a cognitive-behavioral psychotherapy for co-occurring PTSD/SUD. This pilot study with fourteen male OEF/OIF Veterans suggests that SS may help to reduce alcohol use, PTSD, and depression in some participants at clinically significant levels, even when providing less than half of the full model. We emphasize several SS features as especially helpful: the case management component to help engage clients in further mental health and SUD care; offering PTSD as an entry point, and emphasis on community resources. Issues particular to Veterans include reintegration to civilian life and supporting Veterans’ connection with other Veterans. PMID:20464809

There is a paucity of quality measures to assess the care for the range of unhealthy alcohol use, ranging from risky drinking to alcohol use disorders. Using a two-phase expert panel review process, we sought to develop an expanded set of quality of care measures for unhealthy alcohol use, focusing on outpatient care delivered in both primary care and specialty care settings. This process generated 25 candidate measures. Eight measures address screening and assessment, 11 address aspects of treatment, and six address follow-up. These quality measures represent high priority targets for future development, including creating detailed technical specifications and pilot testing them to evaluate their utility in terms of feasibility, reliability, and validity.

Background This study's aim was to compare the dental biofilm metabolite-profile of caries-active (N=11) or caries-free (N=4) children by gas chromatography-mass spectrometry (GC/MS) analyses. Methods Samples collected after overnight fasting, with or without a previous glucose rinse, were combined for each child based on the caries status of the site, re-suspended in ethanol and analyzed by GC/MS. Results Biofilm from caries-active sites exhibited a different chromatographic profile compared to caries-free sites. Qualitative and quantitative analysis suggested a special cluster of branched alcohols and esters present at substantially higher intensity in biofilms of caries-active sites. Conclusions This pilot study indicates that there are metabolites present in the biofilm which have the potential to provide a characteristic metabolomics signature for caries activity.

Pavlovian processes are thought to play an important role in the development, maintenance and relapse of alcohol dependence, possibly by influencing and usurping ongoing thought and behavior. The influence of pavlovian stimuli on ongoing behavior is paradigmatically measured by pavlovian-to-instrumental transfer (PIT) tasks. These involve multiple stages and are complex. Whether increased PIT is involved in human alcohol dependence is uncertain. We therefore aimed to establish and validate a modified PIT paradigm that would be robust, consistent and tolerated by healthy controls as well as by patients suffering from alcohol dependence, and to explore whether alcohol dependence is associated with enhanced PIT. Thirty-two recently detoxified alcohol-dependent patients and 32 age- and gender-matched healthy controls performed a PIT task with instrumental go/no-go approach behaviors. The task involved both pavlovian stimuli associated with monetary rewards and losses, and images of drinks. Both patients and healthy controls showed a robust and temporally stable PIT effect. Strengths of PIT effects to drug-related and monetary conditioned stimuli were highly correlated. Patients more frequently showed a PIT effect, and the effect was stronger in response to aversively conditioned CSs (conditioned suppression), but there was no group difference in response to appetitive CSs. The implementation of PIT has favorably robust properties in chronic alcohol-dependent patients and in healthy controls. It shows internal consistency between monetary and drug-related cues. The findings support an association of alcohol dependence with an increased propensity towards PIT. © 2014 S. Karger AG, Basel.

The use of pesticides in agricultural production originates residues in the environment where they are applied. Pesticide aerial application is a frequent source of exposure to pesticides by persons dedicated to agricultural practices and those living in neighboring communities of sprayed fields. The aim of the study was to assess the genotoxic effects of pesticides in workers occupationally exposed to these chemicals during their aerial application to agricultural fields of Sinaloa, Mexico. The study involved 30 pilots of airplanes used to apply pesticides via aerial application and 30 unexposed controls. Damage was evaluated through the micronucleus assay and by other nuclear abnormalities in epithelial cells of oral mucosa. The highest frequency ratios (FR) equal to 269.5 corresponded to binucleated cells followed by 54.2, corresponding to cells with pyknotic nuclei, 45.2 of cells with chromatin condensation, 3.7 of cells with broken-egg, 3.6 of cells with micronucleus, and 2.0 of karyolytic cells. Age, worked time, smoking, and alcohol consumption did not have significant influence on nuclear abnormalities in the pilots studied. Pesticide exposure was the main factor for nuclear abnormality results and DNA damage. Marked genotoxic damage was developed even in younger pilots with 2 years of short working period, caused by their daily occupational exposure to pesticides.

Preclinical studies suggest that cortical alterations within the prefrontal cortex (PFC) are critical to the pathophysiology of alcohol dependence. Combined transcranial magnetic stimulation (TMS) and electroencephalography (EEG) allows direct assessment of cortical excitability and inhibition within the PFC of human subjects. We report the first application of TMS-EEG to measure these indices within the PFC of alcohol-dependent (ALD) patients post-detoxification. Cortical inhibition was assessed in 12 ALD patients and 14 healthy controls through single and paired-pulse TMS paradigms. Long-interval cortical inhibition indexed cortical inhibition in the PFC. In the motor cortex (MC), short- interval intracortical inhibition and cortical silent period determined inhibition, while intracortical facilitation measured facilitation, resting and active motor threshold indexed cortical excitability. ALD patients demonstrated altered cortical inhibition across the bilateral frontal cortices relative to controls. There was evidence of altered cortical excitability in ALD patients; however, no significant differences in MC inhibition. Our study provides first direct evidence of reduced cortical inhibition in the PFC of ALD patients post-detoxification. Altered cortical excitability in the MC may reflect hyper-excitability within the cortex associated with chronic alcohol consumption. These findings provide initial neurophysiological evidence of disrupted cortical excitability within the PFC of ALD patients.

Keoleian, Victoria; Polcin, Douglas; Galloway, Gantt P.

2015-01-01

Individuals seeking treatment for addiction often experience barriers due to cost, lack of local treatment resources, or either school or work schedule conflicts. Text messaging-based addiction treatment is inexpensive and has the potential to be widely accessible in real time. We conducted a comprehensive literature review identifying 11 published randomized controlled trials (RCTs) evaluating text messaging-based interventions for tobacco smoking, 4 studies for reducing alcohol consumption, 1 pilot study in former methamphetamine (MA) users, and 1 study based on qualitative interviews with cannabis users. Abstinence outcome results in RCTs of smokers willing to make a quit attempt have been positive overall in the short term and as far out as at 6 and 12 months. Studies aimed at reducing alcohol consumption have been promising. More data are needed to evaluate the feasibility, acceptability, and efficacy of this approach for other substance use problems.

Use of a symptom-triggered scale to measure the severity of alcohol withdrawal could reduce the rate of seizures and other complications. The current standard scale, the Clinical Institute of Withdrawal Assessment (CIWA), takes a mean (±SD) of 5 minutes to complete, requiring 30 minutes of nursing time per patient when multiple measures are required. The objective was to assess the feasibility and reliability of a brief scale of alcohol withdrawal severity. The SHOT is a brief scale designed to assess alcohol withdrawal in the emergency department (ED). It includes four items: sweating, hallucinations, orientation, and tremor (SHOT). It was developed based on a literature review and a consensus process by emergency and addiction physicians. The SHOT was first piloted in one ED, and then a prospective observational study was conducted at a different ED to measure its feasibility and reliability. Subjects included patients who were in alcohol withdrawal. One nurse administered the SHOT and CIWA, and the physician repeated the SHOT independently. The SHOT was done only at baseline, before treatment was administered. In the pilot study (12 patients), the SHOT took 1 minute to complete on average, and the CIWA took 5 minutes. Sixty-one patients participated in the prospective study. For the SHOT and the CIWA done by the same nurse, the kappa was 0.88 (95% confidence interval [CI] = 0.52 to 1.0; p < 0.0001), and the Pearson's r was 0.71 (p < 0.001). The kappa for the nurse's CIWA score and the physician's SHOT score was 0.61 (95% CI = 0.25 to 0.97; p < 0.0006), and the Pearson's r was 0.48 (p = 0.002). The SHOTs performed by the nurse and physician agreed on the need for benzodiazepine treatment in 30 of 37 cases (82% agreement, kappa = 0.35, 95% CI = 0.03 to 0.67; p < 0.02). The mean (±SD) time taken by nurses and physicians to complete the SHOT was 1 (± 0.52) minute (median = 0.6 minutes). Seventeen percent of patients scored positive on the SHOT for hallucinations or disorientation. The SHOT has potential as a feasible and acceptable tool for measuring pretreatment alcohol withdrawal severity in the ED. Further research is needed to validate the SHOT, to assess the utility of serial measurements of the SHOT, and to demonstrate that its use reduces length of stay and improves clinical outcomes. © 2010 by the Society for Academic Emergency Medicine.

Nicotine and Nicotine Abstinence Do Not Interfere with GABAA Receptor Neuroadaptations During Alcohol Abstinence.

Alcohol dependence and tobacco smoking are highly comorbid, and treating both conditions simultaneously is controversial. Previously, we showed that tobacco smoking interferes with GABAA receptor neuroadaptations during alcohol withdrawal in humans, while this effect did not occur with continued nicotine use during alcohol abstinence in nonhuman primates. Here, we extend our previous work by measuring GABAA receptor availability with positron emission tomography (PET) during drug abstinence in nonhuman primates exposed to alcohol alone, nicotine and alcohol together, and alcohol abstinence with continued nicotine exposure. Twenty-four adolescent male rhesus macaques orally self-administered alcohol and nicotine, available separately in water and saccharin, over 20 weeks. The groups included alcohol alone (n = 8); nicotine and alcohol with simultaneous abstinence (n = 8); nicotine and alcohol with alcohol abstinence while nicotine was still available (n = 8); and a pilot group of animals consuming nicotine alone (n = 6). Animals were imaged with [(11)C]flumazenil PET to measure binding potential (BPND), an index of GABAA receptor availability. Imaging occurred at baseline (drug-naíve), and following alcohol and/or nicotine cessation at 1 day, 8 days, and 12 weeks of abstinence. Generalized linear mixed models were used to examine the time course of [(11)C]flumazenil BPND during alcohol abstinence across groups. Animals consumed 3.95 ± 1.22 g/kg/d alcohol and 55.4 ± 35.1 mg/kg/d nicotine. No significant group effects were observed in [(11)C]flumazenil BPND during alcohol abstinence; however, a main effect of time was detected. Post hoc analyses indicated that all groups abstaining from alcohol exhibited significantly increased GABAA receptor availability at 1 day and 8 days (but not 12 weeks) of abstinence relative to baseline, while no changes in [(11)C]flumazenil BPND during nicotine abstinence alone were observed. These data indicate that neither nicotine nor nicotine abstinence interferes with GABAA receptor neuroadaptations during alcohol withdrawal. This conclusion is consistent with our previous study and does not contradict the use of nicotine replacement therapies or non-nicotinic-acting pharmaceuticals to quit smoking during alcohol withdrawal from a GABAergic perspective.

Cross-linking methods have been investigated to determine their effect on the performance of polyvinyl alcohol (PVA) films as alkaline battery separators. The following types of cross-linked PVA films are discussed: (1) PVA-dialdehyde blends post-treated with an acid or acid periodate solution (two-step method) and (2) PVA-dialdehyde blends cross-linked during film formation (drying) by using a reagent with both aldehyde and acid functionality (one-step method). Laboratory samples of each cross-linked type of film were prepared and evaluated in standard separator screening tests. Then pilot-plant batches of films were prepared and compared to measure differences due to the cross-linking method. The pilot-plant materials were then tested in nickel oxide-zinc cells to compare the two methods with respect to performance characteristics and cycle life. Cell test results are compared with those from tests with Celgard.

The purpose of our study was to examine the coagulation status in patients with vascular anomalies who had undergone sclerotherapy or embolization. Ours was a prospective pilot study of 29 patients who had undergone sclerotherapy or embolization of large vascular anomalies. Fibrinogen, platelet, and d-dimer levels and prothrombin time were obtained before, immediately after, and on the day after the procedure. Five patients with venous malformations had positive d-dimer levels before the procedure. A subgroup analysis revealed a relationship between the type of agent used and the change in coagulation status. Specifically, a positive relationship was found between the use of dehydrated alcohol or sodium tetradecyl sulfate and a disruption in coagulation profiles as evidenced by a decrease in platelets and fibrinogen, an increase in prothrombin time, and a conversion from negative to positive d-dimers. In contrast, sclerotherapy or embolization with cyanoacrylic, polyvinyl alcohol foam particles, or platinum microcoils was not associated with coagulation disturbances. The coagulation disturbances that occur in response to dehydrated alcohol or sodium tetradecyl sulfate sclerotherapy or embolization could compromise the patient's clotting ability. Patients who receive dehydrated alcohol or sodium tetradecyl sulfate during a preoperative sclerotherapy or embolization may experience coagulation disturbances that could increase the risk of bleeding, thrombosis, or hematoma. This patient population may benefit from the use of glue, foam, or coils as a substitute for dehydrated alcohol or sodium tetradecyl sulfate.

Impact of alcohol harm reduction strategies in community sports clubs: pilot evaluation of the Good Sports program.

Approximately 4.5 million Australians are involved in community sports clubs. A high level of alcohol consumption tends to be commonplace in this setting. The only program of its type in the world, the Good Sports program was designed to reduce harmful alcohol consumption in these Australian community sports clubs. The program offers a staged accreditation process to encourage the implementation of alcohol harm-reduction strategies. We conducted a postintervention adoption study to evaluate whether community sports club accreditation through the Good Sports program was associated with lower rates of alcohol consumption. We examined alcohol consumption rates in 113 clubs (N = 1,968 participants) and compared these to consumption rates in the general community. We hypothesized that members of clubs with more advanced implementation of the Good Sports accreditation program (Stage Two) would consume less alcohol than those with less advanced implementation (Stage One). Multilevel modeling (MLM) indicated that on days when teams competed, Stage Two club members consumed 19% less alcohol than Stage One club members. MLM also indicated that the length of time a club had been in the Good Sports program was associated with reduced rates of weekly drinking that exceeded Australian short-term risky drinking guidelines. However consumption rates for all clubs were still higher than the general community. Higher accreditation stage also predicted reduced long-term risky drinking by club members. Our findings suggest that community sports clubs show evidence of higher levels of alcohol consumption and higher rates of risky consumption than the general community. Implementation of the Good Sports accreditation strategy was associated with lower alcohol consumption in these settings.

To investigate and analysis the prevalence and risk factors of snoring and excessive daytime sleepiness among male pilots. 1108 subjects were derived from a random sample of pilots. They were asked to answer the questions from a questionnaire concerning their snoring and daytime sleepiness, etc. 1054 questionnaire were available for evaluation. The overall prevalence of snoring among male pilots was 51.04% (538/1054), while moderate and severe snorers accounted for 26.28% (227/1054). The prevalence of snoring among male pilots aged over 30 yr was 63.68% (426/669). The prevalence and severity of snoring increase with age and BMI. Age, overweight and obesity, alcohol ingestion and family history of snoring were associated with the prevalence and severity of snoring. There was significant difference in Epworth sleepiness scale scores among without snoring group and various severity of snoring groups (chi2 = 16.948, P < 0.05). The prevalence of snoring is high in male pilots. The Epworth sleepiness scale score increase with increasing degree of snoring. Doctors should pay more attention to snoring in male pilot.

Although negative affect is a common precipitant of alcohol relapse, there are few interventions for alcohol dependence that specifically target negative affect. In this Stage 1a/1b treatment development study, several affect regulation strategies (e.g., mindfulness, prolonged exposure, distress tolerance) were combined to create a new treatment supplement called Affect Regulation Training (ART), which could be added to enhance Cognitive-Behavioral Therapy (CBT) for alcohol dependence. A draft therapy manual was given to therapists and treatment experts before being administered to several patients who also provided input. After two rounds of manual development (Stage 1a), a pilot randomized clinical trial (N = 77) of alcohol-dependent outpatients who reported drinking often in negative affect situations was conducted (Stage 1b). Participants received 12-weekly, 90-minute sessions of either CBT for alcohol dependence plus ART (CBT + ART) or CBT plus a healthy lifestyles control condition (CBT + HLS). Baseline, end-of-treatment, and 3- and 6-month posttreatment interviews were conducted. For both treatment conditions, participant ratings of treatment satisfaction were high, with CBT + ART rated significantly higher. Drinking outcome results indicated greater reductions in alcohol use for CBT + ART when compared to CBT + HLS, with moderate effect sizes for percent days abstinent, drinks per day, drinks per drinking day, and percent heavy drinking days. Overall, findings support further research on affect regulation interventions for negative affect drinkers. PMID:23876455

After two rounds of manual development (stage 1a), a pilot randomized clinical trial (N=77) of alcohol-dependent outpatients who reported drinking often in negative affect situations was conducted (stage 1b). Participants received 12-weekly, 90-minute sessions of either CBT for alcohol dependence plus ART (CBT+ART) or CBT plus a healthy lifestyles control condition (CBT+HLS). Baseline, end-of-treatment, and 3- and 6-month posttreatment interviews were conducted. For both treatment conditions, participant ratings of treatment satisfaction were high, with CBT+ART rated significantly higher. Drinking outcome results indicated greater reductions in alcohol use for CBT+ART when compared to CBT+HLS, with moderate effect sizes for percent days abstinent, drinks per day, drinks per drinking day, and percent heavy drinking days. Overall, findings support further research on affect regulation interventions for negative affect drinkers. © 2013.

This article describes formative research (a pilot study, interviews, and focus groups) conducted as part of a feasibility test of 2 versions (Analysis vs. Planning) of a brief media literacy intervention titled Youth Message Development (YMD). The intervention targets high school student alcohol use with activities to understand persuasion strategies, increase counter-arguing, and then apply these new skills to ad analysis or a more engaging ad poster planning activity. Based on the theory of active involvement (Greene, 2013), the Planning curriculum is proposed to be more effective than the Analysis curriculum. Overall, results of the formative research indicated that students (N = 182) and mentors/teachers (N = 53) perceived the YMD Planning curriculum as more interesting, involving, and novel, and these ratings were associated with increased critical thinking about the impact of advertising, lower alcohol use intentions, and fewer positive expectations about the effects of alcohol use. Qualitative feedback indicated a need to supplement alcohol-focused ad stimuli with ads targeting other advertising images, use incentives and competition-based activities to further enhance student motivation, and provide flexibility to enhance the appropriateness of the curriculum to various settings. These concerns led to the development of a revised curriculum and plans for further study.

Affordable alcohol- and drug-free housing that supports recovery is limited in many areas. Sober living houses (SLHs) offer a unique living environment that supports abstinence and maintenance of a recovery lifestyle. Previous studies show that SLH residents make improvements on alcohol, drug and other problems that are maintained at 18-month follow-up (Polcin et al. 2010). However, for SLHs to maximize their impact they must recognize how they are viewed by community stakeholders and successfully address barriers. This pilot study recruited a convenience sample of two stakeholder groups, certified alcohol and drug counselors (N = 85) and licensed mental health therapists (N = 49), to explore knowledge and views about SLHs using an online survey. Therapists and counselors had similar views about SLHs, although counselors had more direct experience with them and were more knowledgeable. Both groups were highly supportive of increasing the role of SLHs to address addiction problems in their communities. Those who were most supportive had more knowledge about SLHs, agreed that alcohol and drug problems were caused by a physical disease, and agreed that successful recovery required an abstinent living environment. Both groups identified a variety of barriers, particularly social stigma. Recommendations are made for knowledge dissemination and decreasing barriers.

Peracetic acid sporicidal wipes have been shown to be an effective disinfectant, but in controlled test environments. Their high cost may restrict use. This pilot study investigated the efficacy and compared the costs of routine universal use of peracetic acid sporicidal wipes versus sporicidal quaternary ammonium compound and alcohol wipes in the disinfection of a hospital environment. The routine universal use of peracetic acid wipes (Clinell Sporicidal; GAMA Healthcare Ltd, London, UK) was allocated to a study ward, whereas the control ward continued with the use of quaternary ammonium compound wipes (Tuffie 5; Vernacare, Bolton, UK) and alcohol wipes (PDI Sani-Cloth 70; PDI, Flint, UK). Twenty high-touch areas in the 2 wards were sampled for the presence of indicator organisms. The weekly detection rates of indicator organisms and weekly healthcare associated infection (HCAI) rates in the 2 wards were compared and examined for decreasing trends over the trial period. The detection rates of indicator organisms and HCAI rates were not significantly different in the 2 wards, and did not decrease significantly over the trial period. However, the peracetic acid wipes seem to be more effective against gram-negative organisms but at a significantly higher cost. Further prospective studies are needed to assess the cost-effectiveness of peracetic acid wipes. Copyright © 2016 Association for Professionals in Infection Control and Epidemiology, Inc.

This study aimed to assess the impact of a stethoscope disinfection sensitization campaign among doctors and nurses in a Nigerian teaching hospital. The design was a before-and-after study. Pre-program measurements were used to provide a baseline against which the post-program results were compared. Interventions that promoted compliance with stethoscope disinfection practice that were implemented included training and education on stethoscope disinfection and introduction of 70% isopropyl alcohol disinfectant at points-of-care places. Microbiological assessment of stethoscopes used by health workers was conducted after the intervention and the outcome was compared with the pilot study results. After the intervention, of the 89 stethoscopes screened, 18 (20.2%) were contaminated with bacterial agents. A higher prevalence of stethoscope contamination was observed among stethoscopes from the intensive care unit (66.7%), the VIP unit (50%), and the antenatal unit (37.5%). The main isolates were Staphylococcus aureus (44.4%) and Escherichia coli (50%). The antibiotic sensitivity assessment indicated that the bacterial isolates were resistant to nearly all the antibiotics tested. All the 89 health workers whose stethoscopes were screened after the intervention admitted to cleaning their stethoscopes after seeing each patient, representing a compliance rate of 100%, unlike the 15% compliance at the pilot phase. The baseline stethoscope contamination rate was 78.5% versus 20.2% post-intervention. Training and education and introduction of alcohol-based disinfectants inexpensive but very effective methods to improve stethoscope disinfection compliance among health workers in low-income settings.

In this study, corn oil as vegetable oil, chicken fat and fleshing oil as animal fats were used to produce methyl ester in a biodiesel pilot plant. The FFA level of the corn oil was below 1% while those of animal fats were too high to produce biodiesel via base catalyst. Therefore, it was needed to perform pretreatment reaction for the animal fats. For this aim, sulfuric acid was used as catalyst and methanol was used as alcohol in the pretreatment reactions. After reducing the FFA level of the animal fats to less than 1%, the transesterification reaction was completed with alkaline catalyst. Due to low FFA content of corn oil, it was directly subjected to transesterification. Potassium hydroxide was used as catalyst and methanol was used as alcohol for transesterification reactions. The fuel properties of methyl esters produced in the biodiesel pilot plant were characterized and compared to EN 14214 and ASTM D6751 biodiesel standards. According to the results, ester yield values of animal fat methyl esters were slightly lower than that of the corn oil methyl ester (COME). The production cost of COME was higher than those of animal fat methyl esters due to being high cost biodiesel feedstock. The fuel properties of produced methyl esters were close to each other. Especially, the sulfur content and cold flow properties of the COME were lower than those of animal fat methyl esters. The measured fuel properties of all produced methyl esters met ASTM D6751 (S500) biodiesel fuel standards. Copyright © 2014 Elsevier Ltd. All rights reserved.

In obesity and diabetes the liver is highly susceptible to abnormal uptake and storage of fat. In certain individuals hepatic steatosis predisposes to the development of non-alcoholic steatohepatitis (NASH), a disease marked by hepatic inflammation and fibrosis. Although the precise pathophysiology of NASH is unknown, it is believed that the gut microbiota-liver axis influences the development of this disease. With few treatment strategies available for NASH, exploration of gut microbiota-targeted interventions is warranted. We investigated the therapeutic potential of a prebiotic supplement to improve histological parameters of NASH. In a placebo-controlled, randomized pilot trial, 14 individuals with liver-biopsy-confirmed NASH [non-alcoholic fatty liver activity score (NAS) ≥ 5] were randomized to receive oligofructose (8 g/day for 12 weeks followed by 16 g/day for 24 weeks) or isocaloric placebo for 9 months. The primary outcome measure was the change in liver biopsy NAS score and the secondary outcomes included changes in body weight, body composition, glucose tolerance, inflammatory markers, and gut microbiota. Independent of weight loss, oligofructose improved liver steatosis relative to placebo and improved overall NAS score (P = 0.016). Bifidobacterium was enhanced by oligofructose, whereas bacteria within Clostridium cluster XI and I were reduced with oligofructose (P < 0.05). There were no adverse side effects that deterred individuals from consuming oligofructose for treatment of this disease. Independent of other lifestyle changes, prebiotic supplementation reduced histologically-confirmed steatosis in patients with NASH. Larger follow-up studies are warranted. This trial was registered at Clinicaltrials.com as NCT03184376.

The objective of this study was to determine the prevalence of Staphylococcus-contaminated stethoscopes belonging to emergency department (ED) staff and to identify the proportion of these that were Staphylococcus aureus or methicillin-resistant Staphylococcus aureus (MRSA). We conducted a prospective observational cohort study of bacterial cultures from 100 ED staff members' stethoscopes at three EDs. Study participants were asked to complete a questionnaire. Fifty-four specimens grew coagulase-negative staphylococci and one grew methicillin-susceptible S. aureus. No MRSA was cultured. Only 8% of participants, all of whom were nurses, reported cleaning their stethoscope before or after each patient assessment. Alcohol-based wipes were most commonly used to clean stethoscopes. A lack of time, being too busy, and forgetfulness were the most frequently reported reasons for not cleaning the stethoscope in the ED. This study indicates that although stethoscope contamination rates in these EDs are high, the prevalence of S. aureus or MRSA on stethoscopes is low.

Many alcohol-dependent patients suffer from cognitive impairment of variable severity, manifested by alterations in retrograde and anterograde memory, visuospatial processing, cognitive abilities and attention, some of which are reversible. In this context, cognitive remediation therapies could significantly improve patients' performance; therefore, these are considered a valuable alternative. The aim of this study was to implement cognitive remediation therapy in patients with alcohol dependence and cognitive impairment and evaluate its viability and effectiveness. The participants were sixteen abstinent, alcohol-dependent patients (mean age of 59 years, 63% males) from the Addictive Behaviours Unit of a tertiary hospital. Over 6 months, a nurse led 1-hour weekly sessions (24 sessions in total) during which exercises for improving functional, social and cognitive performance were completed. Patients were assessed at baseline, at the end of the study and 6 months later, using the Mini-Mental State Examination (MMSE) and the Memory Alteration Test (M@T). Their respective scores were 26.4 (SD 3.16), 29 (SD 1.67) and 27 (SD 3.1) for the MMSE and 38.7 (SD 6.81), 45.7 (SD 5.6) and 41.1 (SD 7.86) for the M@T. Changes were assessed with both Friedman and Wilcoxon signed-rank tests, with mostly statistically significant differences (p < 0.05). Assistance and satisfaction were high. Therefore, the therapy was viable, widely accepted and effective.

Explore relationships among traumatic brain injury (TBI), substance misuse and other mental health disorders in US service members and to identify risk factors for substance misuse. Service members (n = 93 in final sample) injured while deployed to Operation Enduring Freedom or Operation Iraqi Freedom. Longitudinal survey at 6 and 12 months post-intake. The following measures were used: problem substance use, Alcohol Expectancies Questionnaire-III, MINI International Neuropsychiatric Interview Substance Abuse Modules, Ohio State University TBI Identification Method, Neurobehavioural Symptom Inventory, Rivermead Post-Concussion Symptoms Questionnaire, Buss-Perry Aggression Questionnaire, Post-Traumatic Stress Disorder Checklist-Civilian Version, Beck Depression Inventory-II, Beck Anxiety Inventory. More severe TBI and post-traumatic stress disorder (PTSD) symptoms at 6 months post-enrolment were associated with decreased odds of substance misuse 12 months after study enrolment. Alcohol expectancies and incurring a TBI at a younger age increased the odds of substance misuse. While the ability to generalize the current findings to a larger population is limited, the results provide direction for future studies on the prevention and treatment of substance misuse following TBI. The unexpected protective effect of more severe TBI may result from prospective attention to the injury and its consequences. Greater preventive benefit may result from identifying more service members with elevated risk. Lifetime history of TBI and alcohol expectancies may be candidate indicators for greater attention.

This study adapted an existing computer-delivered brief alcohol intervention (cBAI) for use in Veterans with the hepatitis C virus (HCV) and examined its acceptability and feasibility in this patient population. A four-stage model consisting of initial pilot testing, qualitative interviews with key stakeholders, development of a beta version of the cBAI, and usability testing was used to achieve the study objectives. In-depth interviews gathered feedback for modifying the cBAI, including adding HCV-related content such as the health effects of alcohol on liver functioning, immune system functioning, and management of HCV, a preference for concepts to be displayed through "newer looking" graphics, and limiting the use of text to convey key concepts. Results from usability testing indicated that the modified cBAI was acceptable and feasible for use in this patient population. The development model used in this study is effective for gathering actionable feedback that can inform the development of a cBAI and can result in the development of an acceptable and feasible intervention for use in this population. Findings also have implications for developing computer-delivered interventions targeting behavior change more broadly.

The current pilot study examined the preliminary efficacy of a brief intervention (BI) for at-risk drinking in an employee assistance program. Clients (N = 107) entering the employee assistance program (EAP) for mental health services were screened and met criteria for at-risk drinking. EAP therapists were randomly assigned to deliver either the BI plus EAP services as usual (SAU) or SAU only. Participants in the final analyses consisted of 44 BI + SAU (30 women, 14 men) and 30 SAU (21 women, 9 men) EAP clients who completed a 3-month follow-up. Results suggested that participants in the BI + SAU group had significant reductions in peak blood alcohol concentration, peak quantity, and alcohol-related consequences compared with the SAU group. Men in the BI + SAU group had greater reductions in alcohol-related problems compared with men in the SAU group. Groups did not differ by number of total EAP sessions attended or rates of presenting problem resolution. Results provide preliminary evidence to support the integration of alcohol screening and BI as a low-cost method of intervening with clients with at-risk drinking in the context of co-occurring presenting problems.

This study focused on the efficacy of cognitive training for verbal learning and memory deficits in a population of older veterans with alcohol use disorders. Veterans with alcohol use disorders, who were in outpatient treatment at VA facilities and in early-phase recovery (N = 31), were randomized to receive a three-month trial of daily cognitive training plus work therapy (n = 15) or work therapy alone (n = 16), along with treatment as usual. Participants completed assessments at baseline and at three- and six-month follow-ups; the Hopkins Verbal Learning Task (HVLT) was the primary outcome measure. Participants were primarily male (97%) and in their mid-50s (M = 55.16, SD = 5.16) and had been sober for 1.64 (SD = 2.81) months. Study retention was excellent (91% at three-month follow-up) and adherence to treatment in both conditions was very good. On average, participants in the cognitive training condition had more than 41 hours of cognitive training, and both conditions had more than 230 hours of productive activity. HVLT results at three-month follow-up revealed significant condition effects favoring cognitive training for verbal learning (HVLT Trial-3 T-score, p < .005, Cohen's d = 1.3) and verbal memory (HVLT Total T-score, p < .01, Cohen's d = 1.1). Condition effects were sustained at six-month follow-up. At baseline, 55.9% of participants showed a significant deficit in verbal memory and 58.8% showed a deficit in verbal learning compared with a premorbid estimate of verbal IQ. At three-month follow-up there was a significant reduction in the number of participants in the cognitive training condition with clinically significant verbal memory deficits (p < .01, number needed to treat = 3.0) compared with the work therapy alone condition and a trend toward significance for verbal learning deficits, which was not sustained at six-month follow-up. This National Institute on Drug Abuse-funded pilot study demonstrates that cognitive training within the context of another activating intervention (work therapy) may have efficacy in remediating verbal learning and memory deficits in patients with alcohol use disorder. Findings indicate a large effect for cognitive training in this pilot study, which suggests that further research is warranted. This study is registered on ClinicalTrials.gov (NCT 01410110).

To examine the effects of Sensorimotor Training to Affect Balance, Engagement, and Learning (STABEL), a virtual reality system to train sensory adaptation for balance control, for children with fetal alcohol spectrum disorders (FASDs). Twenty-three children with FASDs received STABEL training in a university laboratory, or home, or were controls. The Movement Assessment Battery for Children-2nd edition (MABC-2) and Pediatric Clinical Test of Sensory Interaction for Balance-2 (P-CTSIB-2) were analyzed by group (lab, home, and control), session (pre-STABEL, 1 week post-STABEL, and 1 month post-STABEL), and group-by-session interaction. Significant effects were group and session for MABC-2 Balance and interaction for MABC-2 Total Motor and P-CTSIB-2. Preliminary results support improved sensory adaptation, balance, and motor performance post-STABEL, which warrant further study with a larger, randomized sample.

Stress is important in substance use disorders (SUDs). Mindfulness training (MT) has shown promise for stress-related maladies. No studies have compared MT to empirically validated treatments for SUDs. The goals of this study were to assess MT compared to cognitive behavioral therapy (CBT) in substance use and treatment acceptability, and specificity of MT compared to CBT in targeting stress reactivity. Thirty-six individuals with alcohol and/or cocaine use disorders were randomly assigned to receive group MT or CBT in an outpatient setting. Drug use was assessed weekly. After treatment, responses to personalized stress provocation were measured. Fourteen individuals completed treatment. There were no differences in treatment satisfaction or drug use between groups. The laboratory paradigm suggested reduced psychological and physiological indices of stress during provocation in MT compared to CBT. This pilot study provides evidence of the feasibility of MT in treating SUDs and suggests that MT may be efficacious in targeting stress.

To investigate alcohol drinking status and the association between drinking patterns and visual impairment in an adult population in northern China. Cluster sampling was used to select samples. The protocol consisted of an interview, pilot study, visual acuity (VA) testing and a clinical examination. Visual impairment was defined as presenting VA worse than 20/60 in any eye. Drinking patterns included drinking quantity (standard drinks per week) and frequency (drinking days in the past week). Information on alcohol consumption was obtained from 8445 subjects, 963 (11.4%) of whom reported consuming alcohol. In multivariate analysis, alcohol consumption was significantly associated with older age (p < 0.001), male sex (p < 0.001), and higher education level (p < 0.01). Heavy intake (>14 drinks/week) was associated with higher odds of visual impairment. However, moderate intake (>1-14 drinks/week) was significantly associated with lower odds (adjusted odds ratio, OR, 0.7, 95% confidence interval, CI, 0.5-1.0) of visual impairment (p = 0.03). Higher drinking frequency was significantly associated with higher odds of visual impairment. Multivariate analysis showed that older age, male sex, and higher education level were associated with visual impairment among current drinkers. Age- and sex-adjusted ORs for the association of cataract and alcohol intake showed that higher alcohol consumption was not significantly associated with an increased prevalence of cataract (OR 1.2, 95% CI 0.4-3.6), whereas light and moderate alcohol consumption appeared to reduce incidence of cataract. Drinking patterns were associated with visual impairment. Heavy intake had negative effects on distance vision; meanwhile, moderate intake had a positive effect on distance vision.

Yeasts Diversity in Fermented Foods and Beverages

NASA Astrophysics Data System (ADS)

Tamang, Jyoti Prakash; Fleet, Graham H.

People across the world have learnt to culture and use the essential microorganisms for production of fermented foods and alcoholic beverages. A fermented food is produced either spontaneously or by adding mixed/pure starter culture(s). Yeasts are among the essential functional microorganisms encountered in many fermented foods, and are commercially used in production of baker's yeast, breads, wine, beer, cheese, etc. In Asia, moulds are predominant followed by amylolytic and alcohol-producing yeasts in the fermentation processes, whereas in Africa, Europe, Australia and America, fermented products are prepared exclusively using bacteria or bacteria-yeasts mixed cultures. This chapter would focus on the varieties of fermented foods and alcoholic beverages produced by yeasts, their microbiology and role in food fermentation, widely used commercial starters (pilot production, molecular aspects), production technology of some common commercial fermented foods and alcoholic beverages, toxicity and food safety using yeasts cultures and socio-economy

Risky drinking is a significant public health issue in young Australian adults. Brief interventions are one of few effective methods of reducing risky drinking but are time and cost intensive; innovative methods of delivery are therefore of interest. Mobile phones offer new opportunities to collect data and intervene during risky drinking events. Mobile phones have successfully been used for delivery of alcohol-related brief interventions and data collection but not in combination with or during drinking events. This pilot study will investigate the efficacy of an ecological momentary intervention (EMI), with combined ecological momentary assessment (EMA) and brief intervention delivered by mobile phones to young adults during risky drinking events. We will use a 3-armed randomized controlled trial to investigate the efficacy of the intervention for reducing peak single occasion drinking. Our sample is recruited from an observational cohort study of young, risky drinkers. Participants will be randomized into 1 of 3 intervention arms. On 6 nights across a 12-week study period, EMI and EMA groups will complete hourly EMA surveys on their mobile phone. EMI participants will receive tailored feedback short message service (SMS) texts corresponding to their EMA survey responses. The EMI participants will not receive feedback SMS. A third group will have no contact (no-contact control). All groups will then be contacted for a follow-up interview within 4 weeks of the 12-week study period ending. The primary outcome is mean reduction in standard drinks consumed during their most recent heavy drinking occasion as measured at follow-up. Secondary outcomes include alcohol consumption over the previous 6 months, experiences of alcohol-related harms, attitudes toward drinking and drunkenness, hazardous drinking and use of tobacco and illicit drugs. A random effects mixed modelling approach using maximum likelihood estimation will be used to provide estimates of differences in mean drinking levels between those receiving the intervention and control participants. This study is novel in that, unlike previous work, it will intervene repeatedly during single occasion drinking events. Further, it extends previous research in this area, which has applied limited tailoring of message content for SMS-based brief interventions. The findings of this study will contribute to the growing body of evidence to inform the use of mobile health interventions for reducing alcohol consumption and harms.

Minimal hepatic encephalopathy (MHE) is highly prevalent, observed in up to 80% of patients with liver dysfunction. Minimal hepatic encephalopathy is defined as hepatic encephalopathy with cognitive deficits and no grossly evident neurologic abnormalities. Clinical management may be delayed due to the lack of in vivo quantitative methods needed to reveal changes in brain neurobiochemical biomarkers. To gain insight into the development of alcoholic liver disease-induced neurological dysfunction (NDF), a mouse model of late-stage alcoholic liver fibrosis (LALF) was used to investigate changes in neurochemical levels in the thalamus and hippocampus that relate to behavioral changes. Proton magnetic resonance spectroscopy of the brain and behavioral testing were performed to determine neurochemical alterations and their relationships to behavioral changes in LALF. Glutamine levels were higher in both the thalamus and hippocampus of alcohol-treated mice than in controls. Thalamic levels of taurine and creatine were significantly diminished and strongly correlated with alcohol-induced behavioral changes. Chronic long-term alcohol consumption gives rise to advanced liver fibrosis, neurochemical changes in the nuclei, and behavioral changes which may be linked to NDF. Magnetic resonance spectroscopy represents a sensitive and noninvasive measurement of pathological alterations in the brain, which may provide insight into the pathogenesis underlying the development of MHE.

In the present study, a pilot-scale reactor incorporating polyvinyl alcohol gel beads as biomass carrier and operating in biological activated sludge mode (a combination of moving bed biofilm reactor (MBBR) and activated sludge) was investigated for the treatment of actual municipal wastewater. The results, during a monitoring period of 4 months, showed effective removal of chemical oxygen demand (COD), biological oxygen demand (BOD) and NH3-N at optimum conditions with 91%, ∼92% and ∼90% removal efficiencies, respectively. Sludge volume index (SVI) values of activated sludge varied in the range of 25-72 mL/g, indicating appreciable settling characteristics. Furthermore, soluble COD and BOD in the effluent of the pilot plant were reduced to levels well below discharge limits of the Punjab Pollution Control Board, India. A culture dependent method was used to enrich and isolate abundant heterotrophic bacteria in activated sludge. In addition to this, 16S rRNA genes analysis was performed to identify diverse dominant bacterial species in suspended and attached biomass. Results revealed that Escherichia coli, Pseudomonas sp. and Nitrosomonas communis played a significant role in biomass carrier, while Acinetobactor sp. were dominant in activated sludge of the pilot plant. Identification of ciliated protozoa populations rendered six species of ciliates in the plant, among which Vorticella was the most dominant.

The acute effect of pleasurable music on craving for alcohol: A pilot crossover study.

PubMed

Mathis, Walter S; Han, Xiaotong

Chronic administration of drugs of abuse leads to a dopamine deficient state in the mesolimbic system, causing dysphoria in abstinence and contributing to craving and return to use. Recent functional imaging studies have shown that listening to personally pleasing music activates the mesolimbic reward system in a fashion similar to drugs of abuse. It has been proposed that such activation could ameliorate the dysphoria and craving of the hypodopaminergic state. The present study sought to evaluate the efficacy of listening to personally pleasing or moving music on reducing craving in abstinent alcoholics using a single-blind, within-subject randomized block design, with three randomly determined presentations of each condition. Twelve participants with Alcohol Use Disorder on a residential substance rehabilitation unit reported their level of craving with a Visual Analog Scale before and after listening to either the participant-selected song or white noise. Using a mixed model to analyze the crossover design, the music intervention was found to have a statistically significant advantage in craving reduction compared to the noise control. Our results indicate that personally pleasing music might have a role in augmenting substance use disorder treatment via craving reduction. Further study is warranted to elucidate factors which predict the most robust response from this intervention. Copyright © 2017 Elsevier Ltd. All rights reserved.

As adolescents gain freedom to explore new environments unsupervised, more time in proximity to alcohol outlets may increase risks for alcohol and marijuana use. This pilot study: 1) Describes variations in adolescents' proximity to outlets by time of day and day of the week, 2) Examines variations in outlet proximity by drinking and marijuana use status, and 3) Tests feasibility of obtaining real-time data to study adolescent proximity to outlets. U.S. adolescents (N = 18) aged 16-17 (50% female) carried GPS-enabled smartphones for one week with their locations tracked. The geographic areas where adolescents spend time, activity spaces, were created by connecting GPS points sequentially and adding spatial buffers around routes. Proximity to outlets was greater during after school and evening hours. Drinkers and marijuana users were in proximity to outlets 1½ to 2 times more than non-users. Findings provide information about where adolescents spend time and times of greatest risk, informing prevention efforts.

Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease in the United States. Binge eating disorder (BED) is the most common form of eating disorder. NAFLD and BED have similar risk factors, including obesity, insulin resistance, and metabolic syndrome. The aim of our study was to examine prevalence of BED in NAFLD patients. We administered the Binge Eating Scale (BES), a questionnaire validated to screen for BED, to NAFLD patients at our Fatty Liver Center. Demographics were retrieved retrospectively from our electronic medical record. Of the total 95 NAFLD patients screened, 22 (23.1%) had binge eating tendencies; 6 of the 22 (6.3%) scored 27 or more points, suggestive of severe binge eating. Patient demographics included 59 females and 36 males (14 females and 8 males positive for BED). Liver disease severity and of metabolic syndrome presence were similar in both groups: 45 patients had steatosis, 25 steatohepatitis, and 24 cirrhosis, of which 10 steatosis, 5 steatohepatitis, and 7 cirrhosis patients screened positive for BED. Of the NAFLD patients with BED, 50.0% had insulin resistance, 68.2% hypertension, and 50.0% hyperlipidemia, whereas among non-BED NAFLD patients 58.9% had insulin resistance, 63.0% hypertension, and 67.1% hyperlipidemia. This pilot study suggests that BED may have a higher prevalence among NAFLD patients than in the general population. Based on these preliminary results, further study into the prevalence of BED is recommended. More data is need to identify effects of BED on the progression of NAFLD and role of BED treatment.

Background Stress is important in substance use disorders (SUDs). Mindfulness training (MT) has shown promise for stress-related maladies. No studies have compared MT to empirically-validated treatments for SUDs. Goals to assess MT compared to cognitive behavioral therapy (CBT) in substance use and treatment acceptability, and specificity of MT compared to CBT in targeting stress reactivity. Methods 36 individuals with alcohol and/or cocaine use disorders were randomly assigned to receive group MT or CBT in an outpatient setting. Drug use was assessed weekly. After treatment, responses to personalized stress provocation were measured. Results Fourteen individuals completed treatment. There were no differences in treatment satisfaction, or drug use between groups. The laboratory paradigm suggested reduced psychological and physiological indices of stress during provocation in MT compared to CBT. Conclusions This pilot study provides evidence of the feasibility of MT in treating SUDs and suggests that MT may be efficacious in targeting stress. PMID:19904666

Risky alcohol use among service members is a threat to both military readiness and the health of service members. This report describes an analysis using the Defense Medical Surveillance System (DMSS) to identify all active component service members who returned from deployment and completed the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) alcohol use screen as part of the Post Deployment Health Assessment (PDHA) and Post Deployment Health Reassessment (PDHRA) during 2008-2014. This analysis identified that 3.4% of PDHA forms and 4.8% of PDHRA forms completed indicated severe risk for alcohol abuse, defined as an AUDIT-C score of 8 or higher. Among those at severe risk on the PDHRA who were not already under care for alcohol abuse, only 37.7% received a referral for treatment: 21.7% to primary care, 13.4% to behavioral health in primary care, 7.5% to mental health specialty care, and 5.6% to a substance abuse program. Referrals for treatment for those at severe risk were lower than their respective counterparts among males, white non-Hispanics, members of the Air Force, junior officers, and pilots/air crew. There were significant trends of increasing frequencies of subsequent injury and alcohol-related conditions as alcohol use levels increased.

23 years of toxicology testing fatally injured pilots: Implications for aviation and other modes of transportation.

McKay, Mary Pat; Groff, Loren

2016-05-01

Use of over-the-counter, prescription, and illicit drugs is increasing in the United States (US). Many of these drugs are psychoactive and can affect the user's ability to safely operate a vehicle. However, data about drug use by vehicle operators is typically limited to a small proportion of operators and a short list of drugs. For instance, required testing for commercial vehicle operators following most accidents is limited to a urine test for 11 drugs. By comparison, the Federal Aviation Administration (FAA), routinely tests fatally injured pilots' blood and tissues for hundreds of compounds. This study used the results from these tests to assess drug use in aviation. Using matched data from the FAA's Civil Aerospace Medical Institute toxicology database and the National Transportation Safety Board's (NTSB's) aviation accident database, this study examined trends in the prevalence of over-the-counter, prescription, and illicit drugs identified in toxicology tests of fatally injured pilots between 1990 and 2012. Cases that failed to match or where toxicology testing had not been performed were excluded. Pilots identified by the NTSB investigation as being the "flying pilot" at the time of the accident and results from blood or tissues were included. Toxicology results for ethanol and other alcohols were not included. Positive test results were categorized by drug type and potential for causing impairment. Analysis used SPSS Version 19.1 to perform linear by linear chi-squared statistics. The study included 6677 pilots or 87% of the eligible subjects. The large majority were male (98%) and flying general aviation operations (96%) at the time of their fatal accident. There were increasing trends in pilots' use of all drugs, potentially impairing drugs, drugs used to treat potentially impairing conditions, drugs designated as controlled substances, and illicit drugs. The most common potentially impairing drug pilots had used was diphenhydramine, a sedating antihistamine that is an active ingredient in many over-the-counter allergy formulations, cold medicines, and sleep aids in the US. Although evidence of illicit drug use was found only in a small number of cases, the percentage of pilots testing positive for marijuana use increased during the study period, mostly in the last 10 years.

Paukste, Ernesta; Harris, Neil

2015-04-01

Alcohol, tobacco and other drugs (ATODs) usage among adolescents, particularly those living in lower socioeconomic communities, is a population health problem in Australia that requires innovative health promotion strategies. There is a growing recognition of the potential of arts-based approaches to engage youth in health promoting activities. This paper presents the process evaluation of the pilot VoxBox intervention that used rap to build adolescents' awareness of risks associated with ATODs. The VoxBox intervention was piloted in Logan, Queensland, at five high schools with 18 adolescents completing the intervention. Data collection methods included observation, focus groups, semi-structured interviews and a survey of adolescent participants. The intervention was well received by participants and stakeholders. Three factors characterising the project's successful engagement of adolescents were: participate - go with the flow, learning from the real deal and resourced to make some noise. In VoxBox, the emphasis on engaging adolescents in an activity of real interest that was appropriately resourced and delivered was central to credibility and success. SO WHAT?: The findings highlight the importance of interventions matching the interests of the targeted population group.

Adolescents with Intellectual Disability (ID) are at risk for tobacco and alcohol use, yet little or no prevention programs are available for this group. 'Prepared on time' is an e-learning program based on the attitude - social influence - efficacy model originally developed for fifth and sixth grades of mainstream primary schools. The goals of this study were (1) to examine the lifetime use of tobacco and alcohol among this target group and (2) to gain a first impression of the efficacy of 'Prepared on time' among 12-16-year old students with moderate or mild ID (MMID). Students form three secondary special-needs schools were assigned to the experimental (e-learning) group (n=37) or the control group (n=36). Pre-intervention and follow-up data (3 weeks after completion) were gathered using semi-structured interviews inquiring about substance use among students with MMID and the behavioral determinants of attitude, subjective norm, modelling, intention, and knowledge. The lifetime tobacco use and alcohol consumption rates in our sample were 25% and 59%, respectively. The e-learning program had a positive effect on the influence of modelling of classmates and friends. No significant effects were found on other behavioral determinants and knowledge. A substantial proportion of adolescents with MMID in secondary special-needs schools use tobacco or alcohol. This study showed that an e-learning prevention program can be feasible for adolescents with MMID. Copyright © 2016 Elsevier Ltd. All rights reserved.

Directional errors of movements and their correction in a discrete tracking task. [pilot reaction time and sensorimotor performance

Subjects can correct their own errors of movement more quickly than they can react to external stimuli by using three general categories of feedback: (1) knowledge of results, primarily visually mediated; (2) proprioceptive or kinaesthetic such as from muscle spindles and joint receptors, and (3) corollary discharge or efference copy within the central nervous system. The effects of these feedbacks on simple reaction time, choice reaction time, and error correction time were studied in four normal human subjects. The movement used was plantarflexion and dorsiflexion of the ankle joint. The feedback loops were modified, by changing the sign of the visual display to alter the subject's perception of results, and by applying vibration at 100 Hz simultaneously to both the agonist and antagonist muscles of the ankle joint. The central processing was interfered with when the subjects were given moderate doses of alcohol (blood alcohol concentration levels of up to 0.07%). Vibration and alcohol increase both the simple and choice reaction times but not the error correction time.

Innovations in the brewing industry: light beer.

PubMed

Blanco, Carlos A; Caballero, Isabel; Barrios, Rosa; Rojas, Antonio

2014-09-01

The demand for light beers has led brewers to innovate by developing light beer. However, these products are not widely accepted in Europe compared to North America and Australasia because of their lack of fullness in the taste and low bitterness compared with conventional beer. The lower levels of some important compounds, present in light beer, can explain these features since they are responsible for the characteristics of the beer. These include alcohol soluble proteins, oligosaccharides, glycerol, polyphenols, iso-α-acids, fusel alcohols and trihydroxy fatty acids. Light beer is produced by several methods, the most commonly used is the addition of glucoamylase to the wort before or during fermentation. This enzyme metabolizes residual carbohydrates (mainly dextrins) transforming them into fermentable sugars and reducing the caloric and alcohol content in this type of beer. Recently pilot studies have been carried out with genetically engineered yeast strains in which amylolytic genes are introduced into the yeast genome in order to metabolize carbohydrate residues. When introducing amylolytic genes, a better fermentability occurs although the fullness of flavor still becomes reduced.

Being able to measure the acute effects of alcohol consumption on psychomotor functions in natural settings could be useful in injury prevention interventions. This study examined the feasibility and acceptability of collecting app-based measures of information processing, working memory, and gait stability during times of typical alcohol consumption among young adults. Ten young adults (aged 21-26) with hazardous drinking completed a baseline assessment and ecological momentary assessments (EMA) on 4 consecutive Fridays and Saturdays, every hour from 8 pm to 12 am. EMA assessed alcohol consumption and perceived intoxication, followed by a digit symbol substitution task (DSST), a visuospatial working memory task (VSWMT), and a 5-step tandem gait task (TGT). Exit interviews probed user experiences. Multilevel models explored relationships between estimated blood alcohol concentration (eBAC; mg/dL) and DSST and VSWMT performance. Participants completed 32% of EMA. Higher rates of noninitiation occurred later in the evening and over time. In multilevel models, higher eBAC was associated with lower DSST scores. Eight out of 10 individuals had at least 1 drinking occasion when they did not perceive any intoxication. Lower DSST scores would identify impairment in 45% of these occasions. Exit interviews indicated that adding real-time feedback on task performance could increase awareness of alcohol effects. Collecting app-based psychomotor performance data from young adults during drinking occasions is feasible and acceptable, but strategies to reduce barriers to task initiation are needed. Mobile DSST is sensitive to eBAC levels and could identify occasions when an individual may not perceive impairments.

The association between harmful use of alcohol and HIV infection is well documented. To address this dual epidemic, the US President's Emergency Plan for AIDS Relief (PEPFAR) developed and implemented a multi-pronged approach primarily in Namibia and Botswana. We present the approach and preliminary results of the public health investigative and programmatic activities designed, initiated and supported by PEPFAR to combat the harmful use of alcohol and its association as a driver of HIV morbidity and mortality from 2008 to 2013. PEPFAR supported comprehensive alcohol programming using a matrix model approach that combined the socio-ecological framework and the Alcohol Misuse Prevention and Intervention Continuum. This structure enabled seven component objectives: (1) to quantify harmful use of alcohol through rapid assessments; (2) to develop and evaluate alcohol-based interventions; (3) to promote screening programs and alcohol abuse resource services; (4) to support stakeholder networks; (5) to support policy interventions and (6) structural interventions; and (7) to institutionalize universal prevention messages. Targeted PEPFAR support for alcohol activities resulted in several projects to address harmful alcohol use and HIV. Components are graphically conceptualized within the matrix model, demonstrating the intersections between primary, secondary and tertiary prevention activities and individual, interpersonal, community, and societal factors. Key initiative successes included leveraging alcohol harm prevention activities that enabled projects to be piloted in healthcare settings, schools, communities, and alcohol outlets. Primary challenges included the complexity of multi-sectorial programming, varying degrees of political will, and difficulties monitoring outcomes over the short duration of the program.

Goal-directed arm movements in children with fetal alcohol syndrome: a kinematic approach.

2011-02-01

Although many studies have documented deficits in general motor functioning in children with fetal alcohol syndrome (FAS), few have employed detailed measurements to explore the specific nature of such disabilities. This pilot study explores whether three-dimensional (3D) kinematic analysis may generate increased knowledge of the effect of intrauterine alcohol exposure on motor control processes by detecting atypical upper-limb movement pattern specificity in children with FAS relative to typically developing (TD) children. Left and right arm and head movements during a sequential unimanual goal-directed precision task in a sample of children with FAS and in TD children were registered by an optoelectronic tracking system (ProReflex, Qualisys Inc.). Children with FAS demonstrated evidently poorer task performance compared with TD children. Additionally, analyses of arm movement kinematics revealed atypical spatio-temporal organization in the children with FAS. In general, they exhibited longer arm movement trajectories at both the proximal and distal level, faster velocities at the proximal level but slower at the distal level, and more segmented distal movements. Children with FAS also showed atypically augmented and fast head movements during the task performance. Findings indicate neuromotor deficits and developmental delay in goal-directed arm movements because of prenatal alcohol exposure. It is suggested that 3D kinematic analysis is a valid technique for furthering the understanding of motor control processes in children with FAS/fetal alcohol spectrum disorders. A combination with relevant neuroimaging techniques in future studies would enable a more clear-cut interpretation of how atypical movement patterns relate to underlying brain abnormalities. © 2010 The Author(s).

Alcohol use, "alcohol abuse," and illicit drug use were investigated in a representative sample of 1076 urban, northern Italian high school students aged 14 to 19 years in 2001. In addition to questions on substance use, the participants were asked about school achievements and perceived substance use among friends. All the students were submitted to Zuckerman Sensation Seeking Scale (SSS) scale, Eysenck Personality Questionnaire (EPQ), Buss-Durkee Hostility Inventory (BDHI), and Parental Bonding Instrument (PBI). Lifetime alcohol use was found in 80.5%, "alcohol abuse" in 37.7%, cannabis use in 26.2%, ecstasy in 2.8%, heroin in 3.8%, and cocaine in 8.3% of the students: gender differences were significant for alcohol use, "alcohol abuse" and ecstasy use, with male subjects outnumbering females, but not for reported cannabis, heroin, and cocaine use. Early substance use onset among adolescents aged 14-16 years was detected. Higher sensation seeking on SSS, social coping impairment on EPQ, direct aggressiveness on BDHI, poor school achievements, and lower parental care on PBI were found associated with illicit drug use and "alcohol abuse" (multiple drugs users). Increased levels of aggressiveness and sensation seeking were evidenced both in minimal experimenters (ME) and habitual users (HU), without any significant difference, in comparison with abstinent students. Similarly, ME scored higher than abstinent subjects on EPQ for social coping impairment, but lower than HU. Parental care perception was lower in HU, but not in ME with, respect to abstinent subjects. Pearson inverse correlation was demonstrated between PBI scores and EPQ maladaptation and BDHI aggressiveness. Data from this preliminary pilot study suggest that temperamental traits and personality changes may be associated to early substance use "proneness" and reduced perception of parental care.

Suicide and Murder-Suicide Involving Aircraft.

2016-04-01

This is a systematic review of suicide and homicide-suicide events involving aircraft. In aeromedical literature and in the media, these very different events are both described as pilot suicide, but in psychiatry they are considered separate events with distinct risk factors. Medical databases, internet search engines, and aviation safety databases were searched in a systematic way to obtain relevant cases. Relevant articles were searched for additional references. There were 65 cases of pilot suicide and 6 cases of passengers who jumped from aircraft found. There were also 18 cases of homicide-suicide found involving 732 deaths. Pilots perpetrated 13 homicide-suicide events. Compared to non-aviation samples, a large percentage of pilot suicides in this study were homicide-suicides (17%). Homicide-suicide events occur extremely rarely. However, their impact in terms of the proportion of deaths is significant when compared to deaths from accidents. There is evidence of clustering where pilot suicides occur after by media reports of suicide or homicide-suicide. Five of six homicide-suicide events by pilots of commercial airliners occurred after they were left alone in the cockpit. This, along with a sixth incident in which active intervention by a Japan Air crew saved 147 lives, suggests that having two flight members in the cockpit is potentially protective. No single factor was associated with the risk for suicide or homicide-suicide. Factors associated with both events included legal and financial crises, occupational conflict, mental illness, and relationship stressors. Drugs and/or alcohol played a role in almost half of suicides, but not in homicide-suicides.

This article presents the short-term effects of a pilot study of keepin'it REAL (Manténte REAL) conducted in central Mexico by a binational team of investigators. This middle school-based model program for preventing substance use was adapted for Mexico linguistically but not culturally. Two Guadalajara public middle schools were recruited and randomly assigned to either implement the prevention program or serve as a control site. The program was implemented in the treatment site by the students' regular teachers, who were trained by the research team. Seventh graders in ten classrooms in the treatment and control schools (N = 432) completed a pretest and posttest survey in Spanish similar to the survey utilized in the original efficacy trial of keepin'it REAL in the US. T-tests and OLS regressions were conducted to determine the effects of the intervention on substance use outcomes. Differences between treatment and control groups in frequency of use of alcohol and tobacco, the two substances of choice in this sample, were significant and in the desired direction. Differences in amount of use were also in the preferred direction but were not significant for alcohol and only marginally significant for tobacco. When the sample was split by gender, statistically significant treatment effects remained for females but were not observed among males. Effects of the linguistically adapted version of keepin'it REAL appears to be driven by the change in female use; however, the difference in male and female outcomes was not statistically significant. Implications for cultural adaptation and prevention in Mexico are discussed from a communication competency perspective. The promising results of the pilot study suggest that the linguistic adaptation was effective, but that a comprehensive cultural adaptation of keepin'it REAL in partnership with Mexican investigators and communities may be warranted.

2017-01-01

Background Brief interventions can reduce alcohol consumption in young people through screening and delivery of personally relevant feedback. Recently, Web and mobile platforms have been harnessed to increase the reach of brief interventions. Existing literature on mobile-based alcohol brief interventions indicates mixed use of theory in developing interventions. There is no research available to guide the development of SMS text messaging (short message service, SMS) interventions delivered during risky drinking events. Objective The aim of this study was to develop and pilot an alcohol-related risk-reduction brief intervention delivered by SMS to Australian young adults during drinking events. This paper describes the development of intervention message content, with specific focus on the context of delivery during drinking events. Methods A sample of 42 young adults attended 4 workshops; these comprised focus-group style discussion on drinking habits and motivations, discussion of intervention design, analysis of existing alcohol media campaigns, and participant development of message content. Data were analyzed thematically. Results Participants described a focus on having fun and blocking out any incongruent negative influences during drinking episodes. For content to be acceptable, nonjudgmental and non-authoritative language was deemed essential. A preference for short, actionable messages was observed, including suggestions for reminders around drinking water, organizing transport home, checking on friends, and plans the next day. Participants were excited about the potential for messages to be tailored to individuals, as previous alcohol-related campaigns were deemed too generic and often irrelevant. Normative-based messages were also perceived as largely irrelevant as participants felt that they understood the drinking-related norms of their immediate peers already. Conclusions Findings from this study offer insights into young adults’ drinking events and practical advice for designing alcohol-related brief interventions. During our formative development process, we demonstrated a neat correspondence between young people’s preferences for alcohol harm reduction interventions and the theoretical principles of brief interventions, including acceptable topics and message style.

Daily affect and substance use covary among college students, but little is known about these associations among young adults not in college. The current pilot study examines associations between positive and negative affect and alcohol and marijuana use, with a focus on differences between college student and nonstudent young adults. High school seniors completed a baseline survey during the spring of 2012 and were then randomly selected to participate in an intensive measurement follow-up. Participants in the follow-up (N = 72, 40.3% men, 77.8% White, 66.7% full-time college students) completed up to 14 consecutive web-based daily surveys during the fall after high school completion. Multilevel models in which days (Level 1) were nested in persons (Level 2) were estimated. Weekend days were associated with increased alcohol use among all young adults, increased marijuana use among college students, and decreased marijuana use among nonstudents. For young adults not in college, greater daily positive affect was associated with increased likelihood of binge drinking, consuming a greater number of drinks, and lower odds of marijuana use; greater daily negative affect was associated with lower odds of alcohol use and lower odds of binge drinking for non-students. For college students, greater daily negative affect was associated with lower odds of marijuana use. Daily affect and alcohol and marijuana use covary among young adults, though these associations differ between students and non-students. Results highlight the need to examine predictors of alcohol and marijuana use among young adults who do not attend college.

Stepped-care has been recommended in the alcohol and other drug field and adopted in a number of service settings, but few research projects have examined this approach. This article aims to describe a pilot trial of stepped-care methods in the treatment of methamphetamine use and depression comorbidity. An adaptive treatment strategy was developed based on recommendations for stepped-care among methamphetamine users, and incorporating cognitive behaviour therapy/motivational intervention for methamphetamine use and depression. The adaptive treatment strategy was compared with a fixed treatment, comprising an extended integrated cognitive behaviour therapy/motivational intervention treatment. Eighteen participants across two study sites were involved in the trial, and were current users of methamphetamines (at least once weekly) exhibiting at least moderate symptoms of depression (score of 17 or greater on the Beck Depression Inventory II). Treatment delivered via the adaptive treatment (stepped-care) model was associated with improvement in depression and methamphetamine use, however, was not associated with more efficient delivery of psychological treatment to this population relative to the comparison treatment. This pilot trial attests to the potential for adaptive treatment strategies to increase the evidence base for stepped-care approaches within the alcohol and other drug field. However, in order for stepped-care treatment in this trial to be delivered efficiently, specific training in the delivery and philosophy of the model is required.

Few effective treatment options exist for cannabis-using youth. This pilot study aimed to test Approach-Avoidance Training to reduce cannabis use with non-treatment-seeking adolescents. Eighty cannabis-using non-treatment-seeking adolescents (average age 19) were recruited from San Diego, California and Charleston, South Carolina, and randomized to complete either six sessions of Cannabis Approach-Avoidance Task Training (CAAT-training) designed to reduce automatic approach biases for cannabis cues or CAAT-sham training. Change in two primary outcome variables was examined: 1) cannabis approach bias and 2) percent cannabis use days over study enrollment. Change in percent alcohol use days over study enrollment was explored as a secondary outcome. A mixed models repeated measures analysis confirmed the group by time interaction effect for approach bias failed to reach statistical significance (p = .06). Significant group by time interaction effects (ps < 0.05) predicted percent days of cannabis and alcohol use over study enrollment. Participants randomized to the avoid cannabis condition (CAAT-training) reported 7% fewer days of cannabis use compared to 0% change for sham; unexpectedly, those in the avoid cannabis condition reported 10% percent more alcohol use days compared to 3% more for sham. Computerized cognitive bias modification paradigms may have utility in reducing adolescent cannabis use. Future work should consider developing a paradigm that addresses both cannabis and alcohol, as well as alternative computerized approaches for coping with addictive behavior in conjunction with bias modification.

Given the documented multiple health risks college students engage in, and the dearth of effective programs addressing them, the authors developed a computer-based brief multiple-health behavior intervention. This study reports immediate outcomes and feasibility of a pilot of this program. Two hundred students attending a midsized university participated. Participants were randomly assigned to the intervention or control program, both delivered via computer. Immediate feedback was collected with the computer program. Results indicate that the intervention had an early positive impact on alcohol and cigarette use intentions, as well as related constructs underlying the Behavior-Image Model specific to each of the 3 substances measured. Based on the implementation process, the program proved to be feasible to use and acceptable to the population. Results support the potential efficacy of the intervention to positively impact behavioral intentions and linkages between health promoting and damaging behaviors among college students.

Persons addicted to alcohol and drugs are at 5–10 times higher risk for suicide as compared to the general population. To address the need for improved suicide prevention strategies in this population, the Preventing Addiction Related Suicide (PARS) module was developed. Pilot testing of 78 patients demonstrated significant post-treatment changes in knowledge (t (66) = 12.07, p= .000) and attitudes (t (75) = 6.82, p = .000) toward suicide prevention issues. Significant gains were maintained at one-month follow-up for changes in knowledge (t (55) = 6.33, p= .000) and attitudes (t (61) = 3.37, p= .0001), with changes in positive help seeking behaviors in dealing with suicidal issues in friends (χ2 (1) =10.49, p = .007), family (χ2 (1) = 9.81, p = .015), and self (χ2 (1) = 19.62, p= .008) also observed. The PARS was also highly rated by treatment staff as feasible within their standard clinical practice. PMID:23375569

Introduction Recent evidence suggests that text messaging may help to reduce problem drinking as an extension to in-person services, but very little is known about the effectiveness of remote messaging on problem drinking as a stand-alone intervention, or how different types of messages may improve drinking outcomes in those seeking to moderate their alcohol consumption. Methods We conducted an exploratory, single-blind randomized controlled pilot study comparing four different types of alcohol reduction-themed text messages sent daily to weekly drink self-tracking texts in order to determine their impact on drinking outcomes over a 12-week period in 152 participants (≈ 30 per group) seeking to reduce their drinking on the internet. Messaging interventions included: weekly drink self-tracking mobile assessment texts (MA), loss-framed texts (LF), gain-framed texts (GF), static tailored texts (ST), and adaptive tailored texts (TA). Poisson and least squares regressions were used to compare differences between each active messaging group and the MA control. Results When adjusting for baseline drinking, participants in all messaging groups except GF significantly reduced the number of drinks consumed per week and the number of heavy drinking days compared to MA. Only the TA and GF groups were significantly different from MA in reducing the number of drinking days. While the TA group yielded the largest effect sizes on all outcome measures, there were no significant differences between active messaging groups on any outcome measure. 79.6% of individuals enrolled in the study wanted to continue receiving messages for an additional 12 weeks at the end of the study. Discussion Results of this pilot study indicate that remote automated text messages delivered daily can help adult problem drinkers reduce drinking frequency and quantity significantly more than once-a-week self-tracking messages only, and that tailored adaptive texts yield the largest effect sizes across outcomes compared to MA. Larger samples are needed to understand differences between messaging interventions and to target their mechanisms of efficacy. PMID:28146560

Project PRIDE (Promoting Resilience In Discriminatory Environments) is an 8-session small group intervention aimed at reducing negative mental and behavioral health outcomes resulting from minority stress. This study reports the results of a one-armed pilot test of Project PRIDE, which aimed to examine the feasibility and potential for efficacy of the intervention in a sample of 33 gay and bisexual men aged 18 to 25. The intervention appeared feasible to administer in two different sites and all participants who completed posttreatment (n = 22) or follow-up (n = 19) assessments reported high satisfaction with the intervention. Small to large effect sizes were observed for increases in self-esteem; small effect sizes were found for decreases in loneliness and decreases in minority stress variables; and small and medium effect sizes were found for reductions in alcohol use and number of sex partners, respectively. Overall, Project PRIDE appears to be a feasible intervention with promise of efficacy. Copyright © 2017. Published by Elsevier Ltd.

This mixed-methods pilot study examined the feasibility, acceptability, and impact of a web-based gratitude exercise (the ‘Three Good Things’ exercise (TGT)) among 23 adults in outpatient treatment for alcohol use disorder (AUD). Participants were randomized to TGT or a placebo condition. The intervention was feasible with high rates of completion. Participants found TGT acceptable and welcomed the structure of daily emails; however, they found it difficult at times and discontinued TGT when the study ended. Participants associated TGT with gratitude, although there were no observed changes in grateful disposition over time. TGT had a significant effect on decreasing negative affect and increasing unactivated (e.g., feeling calm, at ease) positive affect, although there were no differences between groups at the 8 week follow up. Qualitative results converged on quantitative findings that TGT was convenient, feasible, and acceptable, and additionally suggested that TGT was beneficial for engendering positive cognitions and reinforcing recovery.

1996-03-01

Fatal civil aviation crashes in Ontario from 1985 to 1989 were studied. Data regarding accident circumstances, injury patterns and medical factors (disease, alcohol/drugs) which could have contributed to accident causation was obtained from a review of the files of the Chief Coroner for Ontario in Toronto and the aviation occurrence reports of the Transportation Safety Board of Canada. Forty-seven crashes involving mainly general aviation type aircraft but also 2 gyroplanes, 2 ultralights and a glider were reviewed. About half occurred during the cruise phase of the flight. Seventy (40 pilots; 30 passengers) of the 98 occupants died. The bodies of 68 victims were recovered; 63 were dead at the scene and 5 survived up to ten hours after impact. Multiple trauma killed about half of all the victims (n = 34); 29% (n = 20) drowned; 16% (n = 11) and 3% (n = 2) died of head/neck injuries and coronary disease respectively. Neck trauma was observed mostly in pilots and was the most frequent major blunt trauma injury in drowning victims. Passengers sustained relatively more craniofacial fractures and abdominal/retroperitoneal trauma. Pilot error was the most frequent cause of crashes (55%; 26/47 impacts) followed by mechanical failure (15%; 7/47) and adverse weather/environmental conditions (11%; 5/47). Coronary artery disease incapacitated two pilots (4% of crashes) and ethanol intoxication was implicated in two other accidents. Other drugs did not appear to be a definite factor in accident causation.

In 2013, the American Society of Addiction Medicine (ASAM) approved its Standards of Care for the Addiction Specialist Physician. Subsequently, an ASAM Performance Measures Panel identified and prioritized the standards to be operationalized into performance measures. The goal of this study is to describe the process of operationalizing 3 of these standards into quality measures, and to present the initial measure specifications and results of pilot testing these measures in a large health care system. By presenting the process rather than just the end results, we hope to shed light on the measure development process to educate, and also to stimulate debate about the decisions that were made. Each measure was decomposed into major concepts. Then each concept was operationalized using commonly available administrative data sources. Alternative specifications examined and sensitivity analyses were conducted to inform decisions that balanced accuracy, clinical nuance, and simplicity. Using data from the US Veterans Health Administration (VHA), overall performance and variation in performance across 119 VHA facilities were calculated. Three measures were operationalized and pilot tested: pharmacotherapy for alcohol use disorder, pharmacotherapy for opioid use disorder, and timely follow-up after medically managed withdrawal (aka detoxification). Each measure was calculable with available data, and showed ample room for improvement (no ceiling effects) and wide facility-level variability. Next steps include conducting feasibility and pilot testing in other health care systems and other contexts such as standalone addiction treatment programs, and also to study the specification and predictive validity of these measures.

Social aspects of collegiate holiday drinking have been studied frequently, but physiological consequences are often overlooked. This study examined self-reported stress, endocrine and immune indicators in students at an American university before and after their week-long spring break (SB) holiday. Participants (n = 27; 9 males) provided saliva samples and completed surveys pre- and post-SB. Based on their cortisol reaction to SB, participants were grouped as cortisol nonresponders (CNR; n = 14) or increasers (CI; n = 13). Groups were matched on demographics, baseline alcohol use, family history of alcoholism, and SB plans. Differences over time and between groups were examined for α-amylase, quantity/frequency of alcohol use (quantity/frequency index, QFI) and the immunoglobulin A (IgA) to albumin ratio (IgA:albumin). α-Amylase decreased over time. A time × group interaction was noted for QFI, in which CNRs increased drinking over SB, but CIs did not. Time and time × group effects occurred for IgA:albumin. CIs decreased IgA:albumin over SB, whereas CNRs did not. Pre-SB QFI and pre-/post-SB QFI changes were correlated with changes in IgA:albumin. These findings support previously published relationships between blunted cortisol responses and risk for problem drinking, as well as elevated cortisol and decreased immune response. These data also highlight the importance of physiological measures in the study of collegiate holiday drinking. © 2015 S. Karger AG, Basel.

Reduced Social Network Drinking is Associated with Improved Response Inhibition in Women During Early Recovery from Alcohol Use Disorders: A Pilot Study.

Social support for recovery from alcohol use disorders (AUDs) is associated with improvements in self-reported impulsive behavior in individuals treated for AUDs. We build on these findings using a behavioral task-based measure of response inhibition, a well-defined component of impulsivity, to examine the association of disinhibition with alcohol-specific social network characteristics during early recovery. Women (n = 28) were recruited from treatment for AUD within 3 to 4 weeks of their last drink and were assessed at baseline and again 3 months later. Outcome measures were level of disinhibition at baseline and change in disinhibition from baseline to follow-up, measured using a computer-based continuous performance test. The primary independent variables were level of drinking in the social network at baseline and change in network drinking from baseline to follow-up. The sample [50% black, age M (SD) = 42.3 (9.5)] reported high rates of physical and sexual abuse before age 13 (43%), psychiatric disorder (71%), drug use disorder (78%), and previous treatment (71%). More drinking in participants' social networks was associated with greater disinhibition at baseline (β = 12.5, 95% CI = 6.3, 18.7). A reduction in network drinking from baseline to follow-up was associated with reduced disinhibition (β = -6.0, 95% CI = -11.3, -0.78) independent of IQ, recent alcohol consumption, and self-reported negative urgency. This study extends previous findings of an association between social networks and self-reported impulsivity to a neurobehavioral phenotype, response inhibition, suggesting that abstinence-supporting social networks may play a role in cognitive change during early recovery from AUDs.

Alcohol use is a global public health problem, including as a risk factor for HIV infection, but few data are available on the epidemiology of alcohol use and alcohol use disorders (AUD) among young people in sub-Saharan Africa. We conducted a cross-sectional survey among 4 groups of young people aged 15-24 years old (secondary school students, college/university students, employees of local industries and casual labourers) in two regions (Kilimanjaro and Mwanza) of northern Tanzania. Using a multistage stratified random sampling strategy, we collected information on demographics, alcohol use, and behavioural factors. We screened severity of alcohol use using the Alcohol Use Disorder Identification Test (AUDIT) and estimated the quantity and frequency of alcohol consumption using the timeline-follow-back-calendar (TLFB) method. A total of 1954 young people were surveyed. The prevalence of reported alcohol use was higher among males (47-70% ever users and 20-45% current users) than females (24-54% ever users and 12-47% current users). Prevalence of use was substantially higher in Kilimanjaro than Mwanza region. In both regions, participants reported high exposure to alcohol advertisements, and wide alcohol availability. College students reported the highest prevalence of current alcohol use (45% among males; 26% among females) and of heavy episodic drinking (71% among males; 27% among females) followed by casual labourers. Males were more likely to have AUD (an AUDIT score ≥8) than females, with 11-28% of males screening positive for AUD. Alcohol use was associated with male gender, being in a relationship, greater disposable income, non-Muslim religion and a higher number of sexual partners. Alcohol use is a significant problem among young people in northern Tanzania. There is an urgent need to develop, pilot and deliver interventions to help young people delay initiation and reduce levels of harmful drinking, particularly among college students and casual labourers.

To evaluate the short, half and long term effects of treatment of addiction to alcohol or cocaine in the TC run by "Fundacion Salud y Comunidad" (Foundation Health and Community). descriptive pilot study, with a sequential design of cohort. 91 users completed a survey specifically designed to know their evolution at different follow-up periods (1, 3, 5 or 10 years after their exit from the TC): socio-demographic, psychoactive substance use, other variables related to the stay at the TC. Changes between before the TC and the present time regarding variables such as academic, labour, drug consumption, health, family and social adaptation and their criminal behaviour are described. the cohorts showed a relatively common previous socio-demographic pattern having received a similar treatment. The users reported to have diminished the frequent consumption of the main drug, having 48.9% never relapsed even through an occasional consumption of the drug/s. Also they perceived to have improved their health and family relations, as well as their aggressive behaviour and legal problems linked with their consumption of drug/s. after their rehabilitation in a TC, the users report a global decrease of the consumption of drugs and perceive an improvement of their health, family relations, violence and other problems linked to their former drug use.

Occupational exposure to antineoplastic drugs has been documented to result in various adverse health effects. Despite the implementation of control measures to minimize exposure, detectable levels of drug residual are still found on hospital work surfaces. Cleaning these surfaces is considered as one means to minimize the exposure potential. However, there are no consistent guiding principles related to cleaning of contaminated surfaces resulting in hospitals to adopt varying practices. As such, this pilot study sought to evaluate current cleaning protocols and identify those factors that were most effective in reducing contamination on drug preparation surfaces. Three cleaning variables were examined: (1) type of cleaning agent (CaviCide®, Phenokil II™, bleach and chlorhexidine), (2) application method of cleaning agent (directly onto surface or indirectly onto a wipe) and (3) use of isopropyl alcohol after cleaning agent application. Known concentrations of antineoplastic drugs (either methotrexate or cyclophosphamide) were placed on a stainless steel swatch and then, systematically, each of the three cleaning variables was tested. Surface wipes were collected and quantified using high-performance liquid chromatography-tandem mass spectrometry to determine the percent residual of drug remaining (with 100% being complete elimination of the drug). No one single cleaning agent proved to be effective in completely eliminating all drug contamination. The method of application had minimal effect on the amount of drug residual. In general, application of isopropyl alcohol after the use of cleaning agent further reduced the level of drug contamination although measureable levels of drug were still found in some cases.

Background A pilot study was conducted to determine the effects of Spirulina (Arthrospira platensis) on Cretan patients with non-alcoholic fatty liver disease (NAFLD). Spirulina is a filamentous cyanobacterium taken as a dietary supplement. Methods Fifteen adult Cretan outpatients (13 men), median age 48 (range: 29-62) years, with NAFLD were orally supplemented with 6 g of Spirulina (Greek production) per day for six months. Anthropometric characteristics (height, weight, waist circumference), systolic and diastolic blood pressure, complete blood count, biochemical assessments, homeostasis model assessment of insulin resistance (HOMA-IR) index, health-related quality of life and abdominal sonographic findings were recorded and measured, before and after Spirulina supplementation. Results At the end of the 6-month intervention period, the mean levels of aspartate aminotransferase, alanine aminotransferase, gamma-glutamyltransferase, triglycerides, low-density lipoprotein-cholesterol, total cholesterol, and the ratio of total cholesterol to high-density lipoprotein cholesterol were significantly decreased: 38.5%, 37.5%, 26.7%, 24.8%, 9.6%, 9.1%, and 13.5% respectively, whereas the mean levels of high-density lipoprotein-cholesterol and hemoglobin were significantly increased: 4.2% and 4.1% respectively. Spirulina supplementation resulted also in a significant reduction in weight and HOMA-IR index (8.1% and 19.6% respectively) and a significant improvement in health-related quality of life scale. No changes in sonographic findings were observed. Conclusion Spirulina supplementation at a high dosage of 6 g daily in NAFLD patients has strong and multiple beneficial metabolic effects and improves their health-related quality of life.

Butanol is considered as a superior biofuel, which is conventionally produced by clostridial acetone-butanol-ethanol (ABE) fermentation. Among ABE, only butanol and ethanol can be used as fuel alternatives. Coproduction of acetone thus causes lower yield of fuel alcohols. Thus, this study aimed at developing an improved Clostridium acetobutylicum strain possessing enhanced fuel alcohol production capability. For this, we previously developed a hyper ABE producing BKM19 strain was further engineered to convert acetone into isopropanol. The BKM19 strain was transformed with the plasmid pIPA100 containing the sadh (primary/secondary alcohol dehydrogenase) and hydG (putative electron transfer protein) genes from the Clostridium beijerinckii NRRL B593 cloned under the control of the thiolase promoter. The resulting BKM19 (pIPA100) strain produced 27.9 g/l isopropanol-butanol-ethanol (IBE) as a fuel alcohols with negligible amount of acetone (0.4 g/l) from 97.8 g/l glucose in lab-scale (2 l) batch fermentation. Thus, this metabolically engineered strain was able to produce 99% of total solvent produced as fuel alcohols. The scalability and stability of BKM19 (pIPA100) were evaluated at 200 l pilot-scale fermentation, which showed that the fuel alcohol yield could be improved to 0.37 g/g as compared to 0.29 g/g obtained at lab-scale fermentation, while attaining a similar titer. To the best of our knowledge, this is the highest titer of IBE achieved and the first report on the large scale fermentation of C. acetobutylicum for IBE production. © 2013 American Institute of Chemical Engineers.

Hearing impairment from noise exposure has been reported in fix-wing pilots, especially in civilized countries. However, there are few studies on rotary wing aviators and aircraft mechanics, especially in developing countries whose hearing conservative program is not well established. The present study, therefore, was done to evaluate the prevalence of noise induced hearing loss and the contributing factors that may effect both groups of noise-exposed population. Report questionnaires were reviewed and physical examination combined with audiometric records of 34 pilots and 42 mechanics in the Royal Thai Army Aviation Center, Lobburi, were examined. Hearing loss was studied using four categories of significant threshold shift (STS). Amplitude of noise radiated by aircraft was also measured at different distances. No significant difference was found in prevalence of hearing loss in aviators (32.4%) and aircraft mechanics (47.6%), but in the aircraft mechanics group there were more damage of frequency involvement including speech frequency and high frequency and more decibels loss than aviators. The type of hearing protection and smoking index were strongly correlated with hearing loss. Age, flight time and alcohol habit had no significant effect and ninety percent of the subjects had no self awareness of hearing loss. Aircraft mechanics had more severity on hearing loss than aviators. Types of noise protector and cigarette smoking had significant association with hearing loss.

Adolescents with mental health conditions represent a high-risk group for substance use, deliberate self-harm (DSH), and risky sexual behavior. Mental health treatment does not uniformly decrease these risks. Effective prevention efforts are needed to offset the developmental trajectory from mental health problems to these behaviors. This study tested an adjunctive cognitive-behavioral family-based alcohol, DSH, and HIV prevention program (ASH-P) for adolescents in mental healthcare. A two group randomized design was used to compare ASH-P to an assessment only control (AO-C). Participants included 81 adolescents and a parent. Assessments were completed at pre-intervention as well as 1, 6, and 12-months post-enrollment, and included measures of family-based mechanisms and high-risk behaviors. ASH-P relative to AO-C was associated with greater improvements in most family process variables (perceptions of communication and parental disapproval of alcohol use and sexual behavior) as well as less DSH and greater refusal of sex to avoid a sexually transmitted infection. It also had a moderate (but non-significant) effect on odds of binge drinking. No differences were found in suicidal ideation, alcohol use, or sexual intercourse. ASH-P showed initial promise in preventing multiple high-risk behaviors. Further testing of prevention protocols that target multiple high-risk behaviors in clinical samples is warranted.

Monitoring the quality and availability of alcohol and other drug (AOD) services must be a central tenet of any health-related performance measurement system. The Washington Circle Group (WCG), which was convened by the Center for Substance Abuse Treatment Office of Managed Care in March 1998, has developed a core set of performance measures for AOD services for public- and private-sector health plans. It is also collaborating with a broad range of stakeholders to ensure widespread adoption of these performance measures by health plans, private employers, public payers, and accrediting organizations. Four domains were identified, with specific measures developed for each domain: (1) prevention/education, (2) recognition, (3) treatment (including initiation of alcohol and other plan services, linkage of detoxification and AOD plan services, treatment engagement, and interventions for family members/significant others), and (4) maintenance of treatment effects. Four measures that are based on administrative information from health plans and two measures that require a consumer survey of behavioral health care are undergoing extensive pilot testing. The WCG has reached out to a broad range of stakeholders in performance measurement and managed care to acquaint them with the measures and to promote their investigation and adoption. As results of pilot testing become available, these outreach efforts will continue. Performance measures for AOD services need to become an integral part of a comprehensive set of behavioral and physical health performance measures for managed care plans.

The aim of this study was to investigate the prevalence of obesity, alcoholic beverage consumption, unhealthy alcohol use and sudden sleep onset at the wheel among Italian truck drivers. In addition to prevalence rates, this study also aimed at investigating potential predictors for sudden-onset sleepiness and obesity. A sample of truck drivers was extracted from the database of the High Risk Professional Driver Study. Data concerning demographics, anthropometry, medical information and working conditions were collected using anonymous questionnaires. Logistic regression analyses were performed to assess the association of the reported body mass index (BMI), alcohol consumption and sudden sleep onset with working conditions and general lifestyle factors. Three hundred and thirty-five questionnaires were collected. According to their BMI, 45% of the participants were overweight and 21.4% of them were obese. Twenty-four point two percent declared they drank alcoholic beverages during working hours or work breaks and 21.3% of the drivers had an Alcohol Use Disorders Identification Test Consumption (AUDIT C) score ≥ 5 (the threshold value for unhealthy alcohol use). Forty-one point six percent of the interviewees experienced one episode of sudden sleep onset at the wheel per month (5.5% per week and 0.9% daily). Predictive factors for obesity were: length of service (odds ratio (OR) = 1.09, confidence interval (95% CI): 1.04-1.15, p < 0.001) and the AUDIT C total score (OR = 1.34, 95% CI: 1.08-1.66, p = 0.008). Predictive factors for sudden-onset sleepiness at the wheel were: age > 55 years old (OR = 5.22, 95% CI: 1.29-21.1, p = 0.020), driving more than 50 000 km per year (OR = 2.89, 95% CI: 1.37-6.11, p = 0.006) and the Chalder Fatigue Questionnaire (CFQ) score > 11 (adjusted OR = 2.97, 95% CI: 1.22-7.21, p = 0.016). This study strongly emphasizes the need for intervention in order to reduce and prevent important risk factors for the sake of road safety and truck drivers' health.

Neurocognitive findings in compulsive sexual behavior: a preliminary study.

PubMed

Derbyshire, Katherine L; Grant, Jon E

2015-06-01

BACKGROUND AND AIMS :Compulsive sexual behavior (CSB) is a common behavior affecting 3-6% of the population, characterized by repetitive and intrusive sexual urges or behaviors that typically cause negative social and emotional consequences. For this small pilot study on neurological data, we compared 13 individuals with CSB and gender- matched healthy controls on diagnostic assessments and computerized neurocognitive testing. No significant differences were found between the groups. These data contradict a common hypothesis that CSB is cognitively different from those without psychiatric comorbidities as well as previous research on impulse control disorders and alcohol dependence. Further research is needed to better understand and classify CSB based on these findings.

This study was conducted to understand the factors influencing the food habits of restaurant chefs in northern New Jersey. Data was collected from participants (N = 12) using dietary recalls, and semi-structured interviews based on the socio-ecological model. Dietary recall analysis revealed multiple nutritional intake hazards including skipping meals, and substitution of foods rich in fats and sugar for fruits and vegetables, and increased consumption of alcohol. Qualitative data analysis revealed that their food habits were influenced by a repertoire of individual, organizational, and interpersonal factors. The relevance of these findings to nutrition intervention programs for this population is discussed.

[The German promille law--overview and guideline for legal traffic applications].

1. The alcohol level regulation affects everyone who participates in public road, rail, shipping and air traffic. In legal terms a person participating in traffic is anyone who has a direct, physical influence on the traffic flow i.e. as a pedestrian, a vehicle driver, an aircraft captain or a train driver. Participation in any kind of traffic requires a physical, mental and psychological joint effort which is controlled by the central nervous system. The influence of alcohol drastically deteriorates driver performance to the detritment of traffic safety. In cases of traffic law determination of dangerous driving or in cases of the legal limitations of diminished or no responsibility, recognised discoveries in traffic medicine as well as blood alcohol research, psychiatry and statistics have played a significant role. The main medical-scientific used to determine the alcohol level regulation, in particular the borderline cases, essentially rely on on experiments (mainly driving experiments). These experiments are carried out with drivers under the influence of alcohol and who drive road vehicles, particularly motor vehicles. At present, no comparable, scientifically convincing research is available for the other groups of participants in traffic. Therefore, the determination of a universal alcohol level regulation including pedestrians and train drivers for example, can not be justified. Blood alcohol effect has been thoroughly researched, the metabolic reaction is well known, alcohol is easily quantifiable, its effect can be easily reviewed and is reproducible to a large extent. Therefore, due to existence of certain alcohol level values, legal conclusions can be drawn which affect all participants in traffic. The main issue is, that the blood alcohol level taken at the time of the accident is definite, regardless whether it was taken by means by a blood sample or by means of a statement of the amount of alcohol consumed. Whether or not the driving under the influence of alcohol falls under the category of "infringement of the law" or "criminal offence" depends largely on the abstract danger caused to the traffic. According to section 316 StGB a motorized or non-motorized driver under the influence of alcohol is considered to be unsafe if he/she is incapable of driving the vehicle safely for a long span of time or when sudden difficulties arise. It would apply if the alcohol has caused a personality change which would not enable the driver to drive safely despite wilfully trying. This applies respectively to drivers of vehicles that don't circulate on roads. 2. Currently, the following alcohol limit regulation applied in Germany: Criminal offences section 316, section 315 c section 1 no. 1 a StGB 1. Drivers of motor vehicles on the road--0.3 to 1.09/1000 and an additional error to due the consumption of alcohol--1.10/1000 (including the body's alcohol resorption effect) and more, with or without errors due to the consumption of alcohol. 2. Cyclists--0.3 to 1.59/1000 and an additional error due to the consumption of alcohol--1.60/1000 (including the body's resorption effect) and more, with oder without error due to the consumption of alcohol. 3. Carriage drivers, motorized wheelchair users--0.3/1000 and more and an additional error due to the consumption of alcohol. Section 316, Section 315 StGB 4. Train drivers, airplane pilots and persons in charge of ships--0.3/1000 and more and an additional error due to the consumption of alcohol. Author's opinion: airplane pilots, from 0.1/1000 even without an error due to the consumption of alcohol. Infringement of the law section 24 StVG--0.80 (including body's alcohol resorption effect) to 1.09/1000 without error due to the comsumption of alcohol. Sections 2, 69 a section 1 no. 1 StVZO pedestrians with or without special means of transport, animal leaders/animal drovers, pillion rider or passenger on a motor-bike--0.3/1000 and more and an additional error due to the consumption of alc

Previous trials on acupuncture in alcohol addiction were in outpatients and focused on relapse prevention. Rates of dropout were high and interpretation of results difficult. We compared auricular laser and needle acupuncture with sham laser stimulation in reducing the duration of alcohol withdrawal. Inpatients undergoing alcohol withdrawal were randomly allocated to laser acupuncture (n = 17), needle acupuncture (n = 15) or sham laser stimulation (n = 16). Attempts were made to blind patients, therapists and outcome assessors, but this was not feasible for needle acupuncture. The duration of withdrawal symptoms (as assessed using a nurse-rated scale) was the primary outcome; the duration of sedative prescription was the secondary outcome. Patients randomized to laser and sham laser had identical withdrawal symptom durations (median 4 days). Patients randomized to needle stimulation had a shorter duration of withdrawal symptoms (median 3 days; P = 0.019 versus sham intervention), and tended to have a shorter duration of sedative use, but these differences diminished after adjustment for baseline differences. The data from this pilot trial do not suggest a relevant benefit of auricular laser acupuncture for alcohol withdrawal. A larger trial including adequate sham interventions is needed, however, to reliably determine the effectiveness of any type of auricular acupuncture in this condition.

To present time, scientific knowledge about symptoms of common mental disorders and adverse health behaviours among professional soccer players is lacking. Consequently, the aim of the study was to determine the prevalence of symptoms of common mental disorders (distress, anxiety/depression, sleep disturbance) and adverse health behaviours (adverse alcohol behaviour, smoking, adverse nutrition behaviour) among professional soccer players, and to explore their associations with potential stressors (severe injury, surgery, life events and career dissatisfaction). Cross-sectional analyses were conducted on baseline questionnaires from an ongoing prospective cohort study among male professional players. Using validated questionnaires to assess symptoms of common mental disorders and adverse health behaviours as well as stressors, an electronic questionnaire was set up and distributed by players’ unions in 11 countries from three continents. Prevalence of symptoms of common mental disorders and adverse health behaviours among professional soccer players ranged from 4% for smoking and 9% for adverse alcohol behaviour to 38% for anxiety/depression and 58% for adverse nutrition behaviour. Significant associations were found for a higher number of severe injuries with distress, anxiety/depression, sleeping disturbance and adverse alcohol behaviour, an increased number of life events with distress, sleeping disturbance, adverse alcohol behaviour and smoking, as well as an elevated level of career dissatisfaction with distress, anxiety/depression and adverse nutrition behaviour. Statistically significant correlations (p<0.01) were found for severe injuries and career dissatisfaction with most symptoms of common mental disorders. High prevalence of symptoms of common mental disorders and adverse health behaviours was found among professional players, confirming a previous pilot-study in a similar study population.

Field production of scleroglucan biopolymer for micellular flooding near an injection well could eliminate two major polymer production costs, alcohol precipitation of polymer broth and resuspension of dry polymer in water. The use of microscreening could decrease these and another major polymer production cost, that of diatomaceous earth filtration. Bench and pilot tests using Rexnord 1, 6, and 21-..mu..m screens indicate that they provide efficient removal of gross solids from Sclerotium rolfsii culture broth partially diluted to viscosities suitable for field injection. Pilot centrifuge tests indicate that the microscreen backwash could be concentrated to a solid content of 2 tomore » 3% as volatile suspended solids, suitable for animal feed or by-product use. Although polishing filtration is required to remove residual formation plugging constituents, substantial decreases in capital costs and operating energy appear attainable if microscreening is used. 3 figures, 3 tables.« less

This article presents findings of a pilot test of a Motivational Interviewing social network intervention (MI-SNI) to enhance motivation to reduce high risk alcohol and other drug (AOD) use among formerly homeless individuals transitioning to housing. Delivered in-person by a facilitator trained in MI, this four-session computer-assisted intervention provides personalized social network visualization feedback to help participants understand the people in their network who trigger their alcohol and other drug (AOD) use and those who support abstinence. If ready, participants are encouraged to make changes to their social network to help reduce their own high-risk behavior. Participants were 41 individuals (33 male, 7 female, 1 other; 23 African-American, 5 non-Latino White, 6 Latino, 7 other, mean age 48) who were transitioning from homelessness to permanent supportive housing. They were randomly assigned to either the MI-SNI condition or usual care. Readiness to change AOD use, AOD abstinence self-efficacy, and AOD use were assessed at baseline and shortly after the final intervention session for the MI-SNI arm and around 3-months after baseline for the control arm. Acceptability of the intervention was also evaluated. MI-SNI participants reported increased readiness to change AOD use compared to control participants. We also conducted a subsample analysis for participants at one housing program and found a significant intervention effect on readiness to change AOD use, AOD abstinence self-efficacy, and alcohol use compared to control participants. Participants rated the intervention as highly acceptable. We conclude that a brief computer-assisted Motivational Interviewing social network intervention has potential to efficaciously impact readiness to change AOD use, AOD abstinence self-efficacy, and AOD use among formerly homeless individuals transitioning to permanent supportive housing, and warrants future study in larger clinical trials.

Although alcohol and nicotine administration studies have demonstrated that manipulating subjects’ expectancies regarding drug content affects drug response, research with marijuana has not adequately studied drug expectancy effects. The present pilot study was the first to evaluate the credibility and effect of expectancy manipulation on subjective measures and smoking patterns using a marijuana administration balanced-placebo design (BPD). In a 2 × 2 instructional set (told delta-9-tetrahydrocannabinol [THC] vs. told no THC) by drug (smoked marijuana with 2.8% THC vs. placebo) between-subjects design, the authors examined the effect of marijuana expectancy manipulation and the pharmacologic effect on affective and physiologic measures, cigarette ratings, and smoking behavior with 20 marijuana smokers (mean age = 20 years; 25% female). Large main effects of expectancy were found on ratings of cigarette potency, strength, taste, smell, and satisfaction, and observed smoking behavior. Pharmacologic effects were particularly evident for self-reported physical reactions to marijuana and cigarette potency and satisfaction ratings. This study demonstrated the feasibility of the BPD research with marijuana and yielded promising results for future studies examining the independent and combined effects of marijuana pharmacology and expectancies.

Young adult veterans from the wars in Iraq and Afghanistan represent a population at-risk for heavy and problematic alcohol use. Unfortunately, few seek treatment for alcohol concerns and those that do seek care may drop out from lengthy multicomponent treatments. Additionally, veterans who live in rural areas and those who are not engaged in the Veterans Affairs Healthcare System are often overlooked, difficult to engage in treatment, and may not be actively seeking treatment for heavy patterns of use that may develop into an alcohol use disorder. The objective of this proposed randomized controlled trial is to develop and pilot test a brief, stand-alone Internet-based alcohol intervention with young adult veterans to help them reduce their drinking and prevent the development of problematic alcohol use. Recruitment and intervention is delivered entirely over the Internet to address barriers to seeking care among this at-risk group. The online intervention consists of an assessment followed by a single module of personalized normative feedback (PNF), which provides individuals with accurate information to reduce misperceptions regarding the frequency and acceptability of risky peer behavior. PNF has established efficacy as included within multicomponent interventions targeting military populations or as a stand-alone intervention with young adult college students, but has not yet been empirically supported for the at-risk veteran population. This paper describes the development of the PNF intervention content and details the protocol for the intervention study, which will utilize a sample of 600 young adult veterans to examine the efficacy of the brief PNF intervention targeted toward reducing perceived norms, intentions to drink, actual drinking behavior, and consequences. Specific subpopulations of this veteran population, including those with mental health concerns and those differentiated by level of drinking problems, reasons for drinking, and connection to peers, will be examined to support generalizability of the intervention. This intervention has the potential to improve veteran health care by utilizing a novel approach to increase access to care, assist with drinking reductions, and prevent alcohol-related problems.

Aloe barbadensis miller or Aloe vera has been used for therapeutic purposes since ancient times with antifungal activity known to be amongst its medicinal properties. We conducted a pilot study to determine the antifungal properties of Malaysian Aloe vera leaf extract on otomycosis species including Aspergillus niger and Candida albicans. This laboratory-controlled prospective study was conducted at the Universiti Sains Malaysia. Extracts of Malaysian Aloe vera leaf was prepared in ethanol and solutions via the Soxhlet extraction method. Sabouraud dextrose agar cultured with the two fungal isolates were inoculated with the five different concentrations of each extract (50 g/mL, 25 g/mL, 12.5 g/mL, 6.25 g/mL, and 3.125 g/mL) using the well-diffusion method. Zone of inhibition was measured followed by minimum inhibitory concentration (MIC). For A. niger, a zone of inhibition for alcohol and aqueous extract was seen for all concentrations except 3.125 g/mL. There was no zone of inhibition for both alcohol and aqueous extracts of Aloe vera leaf for C. albicans . The MIC values of aqueous and alcohol extracts were 5.1 g/mL and 4.4 g/mL for A. niger and since no zone of inhibition was obtained for C. albicans the MIC was not determined. The antifungal effect of alcohol extracts of Malaysian Aloe vera leaf is better than the aqueous extract for A. niger ( p < 0.001). Malaysian Aloe vera has a significant antifungal effect towards A. niger.

In pursuit of a self-sustaining college alcohol intervention: Deploying gamified PNF in the real world.

Our recent work (Boyle, Earle, LaBrie, & Smith, 2017) showed that the efficacy of personalized normative feedback-based (PNF) college alcohol interventions can be improved through the addition of gamified elements including points, chance, competition, and personal avatars. However, participants in that study were compensated with subject pool credit. In the current study, we piloted an upgraded, smartphone-based version of the game, which was designed to be truly self-sustaining (i.e., engaging enough that students play voluntarily without the presence of external motivators). First-year students were invited to play the game weekly for six rounds, with participants submitting and voting on their own questions each week and receiving a novel type of feedback in addition to standard descriptive PNF: opposite peers' judgments of participants' self-reported drinking behavior, or reflective norms. With no play-based incentives, 222 first-year college students voluntarily played the game, CampusGANDR. ANCOVA models revealed that, relative to participants randomized to receive feedback on control topics during the three intervention rounds, those who received both descriptive and reflective feedback on peer alcohol use had significantly reduced normative perceptions and reduced alcohol use two months post intervention. This was especially true among heavy drinkers. The results suggest that our gamified "GANDR" approach shows promise as a self-sustaining intervention and, further, that high-risk drinkers may benefit disproportionately from this methodology. Thus, self-sustaining interventions represent an encouraging avenue for future research and development and may hold the potential to impact risky college drinking on a large scale.

Field-scale simulation of chemical flooding

Saad, N.

1989-01-01

A three-dimensional compositional chemical flooding simulator (UTCHEM) has been improved. The new mathematical formulation, boundary conditions, and a description of the physicochemical models of the simulator are presented. This improved simulator has been used for the study of the low tension pilot project at the Big Muddy field near Casper, Wyoming. Both the tracer injection conducted prior to the injection of the chemical slug, and the chemical flooding stages of the pilot project, have been analyzed. Not only the oil recovery but also the tracers, polymer, alcohol and chloride histories have been successfully matched with field results. Simulation results indicatemore » that, for this fresh water reservoir, the salinity gradient during the preflush and the resulting calcium pickup by the surfactant slug played a major role in the success of the project. In addition, analysis of the effects of the crossflow on the performance of the pilot project indicates that, for the well spacing of the pilot, crossflow does not play as important a role as it might for a large-scale project. To improve the numerical efficiency of the simulator, a third order convective differencing scheme has been applied to the simulator. This method can be used with non-uniform mesh, and therefore is suited for simulation studies of large-scale multiwell heterogeneous reservoirs. Comparison of the results with one and two dimensional analytical solutions shows that this method is effective in eliminating numerical dispersion using relatively large grid blocks. Results of one, two and three-dimensional miscible water/tracer flow, water flooding, polymer flooding, and micellar-polymer flooding test problems, and results of grid orientation studies, are presented.« less

Young drivers are overrepresented in collisions resulting in fatalities. It is not uncommon for young drivers to socially binge drink and decide to drive a vehicle a few hours after consumption. To better understand the risks that may be associated with this behaviour, the present study has examined the effects of a social drinking bout followed by a simulated drive in undergraduate students on the descending limb of their BAC (blood alcohol concentration) curve. Two groups of eight undergraduate students (n = 16) took part in this study. Participants in the alcohol group were assessed before drinking, then at moderate and low BAC as well as 24 hours post-acute consumption. This group consumed an average of 5.3 ± 1.4 (mean ± SD) drinks in an hour in a social context and were then submitted to a driving and a predicted crash risk assessment. The control group was assessed at the same time points without alcohol intake or social context.; at 8 a.m., noon, 3 p.m. and 8 a.m. the next morning. These multiple time points were used to measure any potential learning effects from the assessment tools (i.e. driving simulator and useful field of view test (UFOV)). Diminished driving performance at moderate BAC was observed with no increases in predicted crash risk. Moderate correlations between driving variables were observed. No association exists between driving variables and UFOV variables. The control group improved measures of selective attention after the third asessement. No learning effect was observed from multiple sessions with the driving simulator. Our results show that a moderate BAC, although legal, increases the risky behaviour. Effects of alcohol expectancy could have been displayed by the experimental group. UFOV measures and predicted crash risk categories were not sentitive enough to predict crash risk for young drivers, even when intoxicated. PMID:25723618

Introduction In the UK, a significant proportion of male remand prisoners have alcohol problems. Alcohol Brief Interventions (ABIs) are an effective component of a population-level approach to harmful and hazardous drinking. ABIs have been shown to reduce the aggregate level of alcohol consumed and therefore reduce harm to the individual and to others. However, in relation to remand prisoners, there is no evidence as to how effective ABIs could be. The aims of this study are therefore to explore the feasibility and acceptability of an ABI for adult male remand prisoners and to develop an ABI for this group to be piloted in a future trial. Methods and analysis The study will comprise three stages. Stage 1: a cross-sectional survey of adult male remand and convicted prisoners (n=500) at one Scottish prison and one English prison will be undertaken to assess acceptability and feasibility of delivering an ABI, as well as prevalence rates of harmful, hazardous and dependent drinking. Stage 2: in-depth interviews will be conducted with a sample of remand prisoners (n=24) who undertook the survey (n=12 in Scotland; n=12 in England). Two focus groups (one in Scotland and one in England) with six to eight key stakeholders associated with alcohol-related healthcare provision in prisons will be conducted to explore views on barriers, facilitators and levers to ABI delivery. Stage 3: through formal intervention mapping, the analysed data will inform the refinement of an acceptable ABI that is feasible to deliver to male remand prisoners. Ethics and dissemination The project has been approved by the National Research Ethics Committee (NRES), National Offender Management System, Health Board Research and Development, Scottish Prison Service and ethics committee at The University of Edinburgh. Results will be published in peer-reviewed journals and presented at local, national and international conferences. PMID:28473514

HIV-affected families report higher rates of harmful alcohol use, intimate partner violence (IPV) and family conflict, which can have detrimental effects on children. Few evidence-based interventions exist to address these complex issues in Sub-Saharan Africa. This mixed methods study explores the potential of a family-based intervention to reduce IPV, family conflict and problems related to alcohol use to promote child mental health and family functioning within HIV-affected families in post-genocide Rwanda. A family home-visiting, evidence-based intervention designed to identify and enhance resilience and communication in families to promote mental health in children was adapted and developed for use in this context for families affected by caregiver HIV in Rwanda. The intervention was adapted and developed through a series of pilot study phases prior to being tested in open and randomized controlled trials (RCTs) in Rwanda for families affected by caregiver HIV. Quantitative and qualitative data from the RCT are explored here using a mixed methods approach to integrate findings. Reductions in alcohol use and IPV among caregivers are supported by qualitative reports of improved family functioning, lower levels of violence and problem drinking as well as improved child mental health, among the intervention group. This mixed methods analysis supports the potential of family-based interventions to reduce adverse caregiver behaviors as a major mechanism for improving child well-being. Further studies to examine these mechanisms in well-powered trials are needed to extend the evidence-base on the promise of family-based intervention for use in low- and middle-income countries.

Persons addicted to alcohol and drugs are at 5-10 times higher risk for suicide as compared to the general population. To address the need for improved suicide prevention strategies in this population, the Preventing Addiction Related Suicide (PARS) module was developed. Pilot testing of 78 patients demonstrated significant post-treatment changes in knowledge [t(66) = 12.07, p = .000] and attitudes [t(75) = 6.82, p = .000] toward suicide prevention issues. Significant gains were maintained at 1-month follow-up for changes in knowledge [t(55) = 6.33, p = .000] and attitudes [t(61) = 3.37, p = .0001], with changes in positive help seeking behaviors in dealing with suicidal issues in friends [χ(2)(1) = 10.49, p = .007], family [χ(2)(1) = 9.81, p = .015], and self [χ(2)(1) = 19.62, p = .008] also observed. The PARS was also highly rated by treatment staff as feasible within their standard clinical practice. Copyright © 2013 Elsevier Inc. All rights reserved.

Given that alcohol misuse elevates risk of suicide death among ideators, the paucity of treatment outcome research for individuals presenting with both suicide ideation and problem drinking is particularly troubling. Dialectical behavior therapy (DBT) skills training, which effectively targets behaviors associated with emotion dysregulation including addictive and suicidal behaviors, provides a fitting model amenable to computerization. As stigma and scarcity stand as potential barriers to treatment, online dissemination platforms provide means for efficient treatment delivery that can augment the utility of suitable interventions. This pilot RCT sought to evaluate the feasibility, acceptability, and preliminary efficacy of an Internet-delivered DBT skills training intervention (iDBT-ST) for suicidal individuals who engage in heavy episodic drinking METHODS: Participants (N = 59) were randomized to receive iDBT-ST immediately or after an 8-week waiting period. Clinical outcomes were suicide ideation, alcohol use, and emotion dysregulation. Participants on average saw a significant reduction in all outcomes over the four-month study period. Compared to waitlist controls, individuals who received iDBT-ST immediately showed faster reductions in alcohol consumption. Preliminary results suggest that iDBT-ST may be a viable resource for the high-risk and underserved group represented in this study, and pathways for future development are suggested. There was difficulty retaining and engaging participants due to technological barriers. Copyright © 2018 Elsevier B.V. All rights reserved.

Hand sanitizer and rates of acute illness in military aviation personnel.

Alcohol-based hand sanitizer (HS) kills most organisms that cause acute illness, an important cause of lost duty time among aviation personnel. This preliminary study observed the impact on the acute illness rate when HS was made readily accessible to pilots. Wall-mounted HS dispensers were placed in two fighter squadron operations buildings during November 2005 and various media were used to alert all base personnel to the importance of hand hygiene and cough hygiene. Data were obtained for two groups of personnel on the same base: 1) pilots who worked in the two HS-equipped buildings (Squadron) (n = 56); and 2) pilots and air traffic controllers who worked at other locations (Non-Squadron) (n = 61). The incidence of acute illness and the cumulative number of duty days lost was determined in each group for the winters of 2004-05 (no HS) and 2005-06 (HS available). For the Squadron group, the acute illness rates were 2.4% in 2004-5 (210 duty days lost) (no HS) compared with 0.9% in 2005-6 (78 duty days lost) when HS was provided. No year-to-year difference was apparent for the Non-Squadron group, where the illness rates were 2.4% in 2004-5 (229 duty days lost) and 2.3% in 2005-6 (221 duty days lost). Making HS readily available at locations frequented by pilots together with educating them regarding hand hygiene may reduce the occurrence of acute illness and number of duty days lost.

Objective: Severely mentally ill youths are at elevated risk for human immunodeficiency virus infection, but little is known about acquired immunodeficiency syndrome (AIDS) risk behavior in adolescents who seek outpatient mental health services or about the links between psychiatric problems and particular high-risk behaviors. This pilot study used structural equation modeling to conduct a path analysis to explore the direct and indirect effects of adolescent psychopathology on risky sex, drug/alcohol use, and needle use. Method: Ethnically diverse youths (N = 86) and their caregivers who sought outpatient psychiatric services in Chicago completed questionnaires of adolescent psychopathology. Youths reported their relationship attitudes, peer influence, sexual behavior, and drug/alcohol use. Results: Different AIDS-risk behaviors were associated with distinct forms of adolescent psychopathology (e.g., delinquency was linked to drug/alcohol use, whereas aggression was related to risky sexual behavior), and peer influence mediated these linkages. Some patterns were similar for caregiver- and adolescent-reported problems (e.g., peer influence mediated the relation between delinquency and drug/alcohol use), but others were different (e.g., caregiver-reported delinquency was associated with risky sex, whereas adolescent-reported delinquency was not). Conclusions: Findings underscore the complexity of factors (types of informants and dimensions of psychopathology) that underlie AIDS risk in troubled youths, and they offer specific directions for designing and implementing uniquely tailored AIDS prevention programs, for example, by targeting delinquent behavior and including high-risk peers and important family members in interventions.

The Internet has increasingly been studied as mode of delivery for interventions targeting problematic alcohol use. Most interventions have been fully automated, but some research suggests that adding counselor guidance may improve alcohol consumption outcomes. An eight-module Internet-based self-help program based on cognitive behavioral therapy (CBT) was tested among Internet help-seekers. Eighty participants with problematic alcohol use according to the Alcohol Use Disorders Identification Test (AUDIT; scores of ≥ 6 for women and ≥ 8 for men) were recruited online from an open access website and randomized into three different groups. All groups were offered the same self-help program, but participants in two of the three groups received Internet-based counselor guidance in addition to the self-help program. One of the guidance groups was given a choice between guidance via asynchronous text messages or synchronous text-based chat, while the other guidance group received counselor guidance via asynchronous text messages only. In the choice group, 65% (13 of 20 participants) chose guidance via asynchronous text messages. At the 10-week post-treatment follow-up, an intention-to-treat (ITT) analysis showed that participants in the two guidance groups (choice and messages) reported significantly lower past week alcohol consumption compared to the group without guidance; 10.8 (SD = 12.1) versus 22.6 (SD = 18.4); p = 0.001; Cohen's d = 0.77. Participants in both guidance groups reported significantly lower scores on the AUDIT at follow-up compared to the group without guidance, with a mean score of 14.4 (SD = 5.2) versus 18.2 (SD = 5.9); p = 0.003; Cohen's d = 0.68. A higher proportion of participants in the guidance groups said that they would recommend the program compared to the group without guidance (81% for choice; 93% for messages versus 47% for self-help). Self-help programs for problematic alcohol use can be more effective in reducing alcohol consumption over a 10-week period when counselor guidance is added. Clinicaltrials.gov NCT02384304.

Excess body weight and heavy alcohol consumption are two of the greatest contributors to global disease. Alcohol use peaks in early adulthood. Alcohol consumption can also exacerbate weight gain. A high body mass index and heavy drinking are independently associated with liver disease but, in combination, they produce an intensified risk of damage, with individuals from lower socio-economic status groups disproportionately affected. We will conduct searches in MEDLINE, Embase, PubMed, PsycINFO, ERIC, ASSIA, Web of Knowledge (WoK), Scopus, CINAHL via EBSCO, LILACS, CENTRAL and ProQuest Dissertations and Theses for studies that assess targeted preventative interventions of any length of time or duration of follow-up that are focused on reducing unhealthy eating behaviour and linked risky alcohol use in 18-25-year-olds. Primary outcomes will be reported changes in: (1) dietary, nutritional or energy intake and (2) alcohol consumption. We will include all randomised controlled trials (RCTs) including cluster RCTs; randomised trials; non-randomised controlled trials; interrupted time series; quasi-experimental; cohort involving concurrent or historical controls and controlled before and after studies. Database searches will be supplemented with searches of Google Scholar, hand searches of key journals and backward and forward citation searches of reference lists of identified papers. Search records will be independently screened by two researchers, with full-text copies of potentially relevant papers retrieved for in-depth review against the inclusion criteria. Methodological quality of RCTs will be evaluated using the Cochrane risk of bias tool. Other study designs will be evaluated using the Cochrane Public Health Review Group's recommended Effective Public Health Practice Project Quality Assessment Tool for Quantitative Studies. Studies will be pooled by meta-analysis and/or narrative synthesis as appropriate for the nature of the data retrieved. It is anticipated that exploration of intervention effectiveness and characteristics (including theory base, behaviour change technique; modality, delivery agent(s) and training of intervention deliverers, including their professional status; and frequency/duration of exposure) will aid subsequent co-design and piloting of a future intervention to help reduce health risk and social inequalities due to excess weight gain and alcohol consumption.

Risky drinking in pregnancy by UK women is likely to result in many alcohol-exposed pregnancies. Studies from the USA suggest that brief intervention has promise for alcohol risk reduction in antenatal care. However, further research is needed to establish whether this evidence from the USA is applicable to the UK. This pilot study aims to investigate whether pregnant women can be recruited and retained in a randomized controlled trial of brief intervention aimed at reducing risky drinking in women receiving antenatal care. The trial will rehearse the parallel-group, non-blinded design and procedures of a subsequent definitive trial. Over 8 months, women aged 18 years and over (target number 2,742) attending their booking appointment with a community midwife (n = 31) in north-east England will be screened for alcohol consumption using the consumption questions of the Alcohol Use Disorders Identification Test (AUDIT-C). Those screening positive, without a history of substance use or alcohol dependence, with no pregnancy complication, and able to give informed consent, will be invited to participate in the trial (target number 120). Midwives will be randomized in a 1:1 ratio to deliver either treatment as usual (control) or structured brief advice and referral for a 20-minute motivational interviewing session with an alcohol health worker (intervention). As well as demographic and health information, baseline measures will include two 7-day time line follow-back questionnaires and the EuroQoL EQ-5D-3 L questionnaire. Measures will be repeated in telephone follow-ups in the third trimester and at 6 months post-partum, when a questionnaire on use of National Health Service and social care resources will also be completed. Information on pregnancy outcomes and stillbirths will be accessed from central health service records before the follow-ups. Primary outcomes will be rates of eligibility, recruitment, intervention delivery, and retention in the study population, to inform power calculations for a definitive trial. The health-economics component will establish how cost-effectiveness will be assessed, and examine which data on health service resource use should be collected in a main trial. Participants' views on instruments and procedures will be sought to confirm their acceptability. The study will produce a full trial protocol with robust sample-size calculations to extend evidence on effectiveness of screening and brief intervention. Current Controlled Trials ISRCTN43218782.

Novel psychoactive substance and other drug use by young adults in Western australia.

There is a lack of information regarding the use of novel psychoactive substances (NPS) in Western Australia. The aim of this study was to pilot-test an online survey to obtain data on the prevalence of NPS and other drug use by young Western Australians aged between 18 and 35 years. The Young Adult Drug and Alcohol Survey (YADAS) was a questionnaire deployed online for a period of six months. Participants were recruited via a combined targeted sampling and snowball methodology. There were 472 valid responses. Overall lifetime use of NPS was relatively high (17.6%), while use in the last year was lower (6.6%). These proportions were comparable to that of cocaine use. The most popular NPS were the synthetic cannabinoids. The proportions of respondents drinking alcohol at risky levels, mixing alcohol with energy drinks, and using pharmaceuticals such as ADHD medications for non-medical reasons were high. The YADAS is the first survey to ascertain the prevalence of use of numerous types of NPS in a large sample of young Western Australian adults. The utilization of an online survey methodology yielded valid results as compared to more intensive surveys, and enables researchers greater flexibility in being able to capture current trends.

As part of a multicenter project supported by the World Health Organization, we developed a web-based intervention to reduce alcohol use and related problems. We evaluated the predictors of adherence to, and the outcomes of the intervention. Success was defined as a reduction in consumption to low risk levels or to <50% of the baseline levels of number of drinks. From the 32,401 people who accessed the site, 3389 registered and 929 completed the full Alcohol Use Disorders Identification Test (AUDIT), a necessary condition to be considered eligible to take part in the intervention. Based on their AUDIT scores, these participants were classified into: low risk users (LRU; n=319) harmful/hazardous users (HHU; n=298) or suggestive of dependence users (SDU; n=312). 29.1% of the registered users (LRU=42; HHU=90; SDU=82) completed the evaluation form at the end of the six-week period, and 63.5% reported low-risk drinking levels. We observed a significant reduction in alcohol consumption in the HHU (62.5%) and SDU (64.5%) groups in relation to baseline. One month after the intervention, in the follow-up, 94 users filled out the evaluation form, and their rate of success was similar to the one observed in the previous evaluation. Logistic regression analyses indicated that HHU participants presented higher adherence than LRU. Despite a relatively low adherence to the program, its good outcomes and low cost, as well as the high number of people that can be reached by a web-based intervention, suggest it has good cost-effectiveness.

Although non-alcoholic fatty liver disease (NAFLD) is the leading aetiology of liver disorders in the world, there is no proven treatment for NAFLD patients with normal or low BMI. The aim of this study was to evaluate the efficacy of synbiotics supplementation in NAFLD patients with normal or low BMI. In this randomised, double-blind, placebo-controlled, clinical trial, fifty patients with NAFLD were assigned to take either a synbiotic supplement or a placebo capsule for 28 weeks. Both groups were advised to follow a healthy lifestyle. At the end of the study, hepatic steatosis and fibrosis reduced in both groups; however, the mean reduction was significantly greater in the synbiotic group rather than in the placebo group (P<0·001). Furthermore, serum levels of fasting blood sugar, TAG and most of the inflammatory mediators reduced in the synbiotic group significantly compared with the placebo group (P<0·05). Our results provide evidence that synbiotic supplementation improves the main features of NAFLD in patients with normal and low BMI, at least partially through reduction in inflammatory indices. Further studies are needed to address the exact mechanism of action of these effects.

Objectives To assess the feasibility of conducting a cost-effectiveness study of using care farms (CFs) to improve quality of life and reduce reoffending among offenders undertaking community orders (COs). To pilot questionnaires to assess quality of life, connection to nature, lifestyle behaviours, health and social-care use. To assess recruitment and retention at 6 months and feasibility of data linkage to Police National Computer (PNC) reconvictions data and data held by probation services. Design Pilot study using questionnaires to assess quality of life, individually linked to police and probation data. Setting The pilot study was conducted in three probation service regions in England. Each site included a CF and at least one comparator CO project. CFs are working farms used with a range of clients, including offenders, for therapeutic purposes. The three CFs included one aquaponics and horticulture social enterprise, a religious charity focusing on horticulture and a family-run cattle farm. Comparator projects included sorting secondhand clothes and activities to address alcohol misuse and anger management. Participants We recruited 134 adults (over 18) serving COs in England, 29% female. Results 52% of participants completed follow-up questionnaires. Privatisation of UK probation trusts in 2014 negatively impacted on recruitment and retention. Linkage to PNC data was a more successful means of follow-up, with 90% consenting to access their probation and PNC data. Collection of health and social-care costs and quality-adjusted life year derivation were feasible. Propensity score adjustment provided a viable comparison method despite differences between comparators. We found worse health and higher reoffending risk among CF participants due to allocation of challenging offenders to CFs, making risk of reoffending a confounder. Conclusions Recruitment would be feasible in a more stable probation environment. Follow-up was challenging; however, assessing reconvictions from PNC data is feasible and a potential primary outcome for future studies. PMID:29550778

Factors affecting maritime pilots' health and well-being: a systematic review.

PubMed

Main, Luana C; Chambers, Timothy P

2015-01-01

Maritime pilotage is a demanding occupation where pilots are required to perform complex procedures in sometimes unfamiliar working environments. These psychological stressors, in addition to the physical demands associated with the role (e.g., reduced sleep, boarding, and departing vessels), may over time have a damaging effect on pilots' physical and mental health. Therefore the aim of this paper was to systematically review the existing literature on maritime pilots' health and well-being. The databases academic search complete, MEDLINE and MEDLINE complete, PsycINFO, PsycARTICLES, PubMed, and ScienceDirect were searched from the earliest available record until 1 May 2015. From an initial pool of 167 manuscripts retrieved, only 18 were peer-reviewed original research and discussed topics associated with maritime pilots' health and well-being. In total, 29 factors associated with maritime pilot health and well-being were identified. These were loosely categorised into physical (n = 14), psychosocial (n = 8), and workplace issues (n = 7). The most commonly investigated factors were blood pressure or heart rate, sleep or fatigue, smoking and alcohol consumption, perceived stress, and shift duration or cycle. Findings from the review suggest that the prevention of cardiovascular diseases and associated cardio-metabolic risk factors seems to be of paramount importance, with ample evidence indicating that modern-day pilots present as being overweight or obese. What remains unknown is whether these physical factors are associated with variations in psychosocial functioning. Therefore, it is recommended that future pilotage investigations adopt a multidisciplinary approach to better quantify the impact of maritime pilotage on long-term health and well-being.

Influence of Volatile Anesthesia on the Release of Glutamate and other Amino Acids in the Nucleus Accumbens in a Rat Model of Alcohol Withdrawal: A Pilot Study

Background Alcohol withdrawal syndrome is a potentially life-threatening condition, which can occur when patients with alcohol use disorders undergo general anesthesia. Excitatory amino acids, such as glutamate, act as neurotransmitters and are known to play a key role in alcohol withdrawal syndrome. To understand this process better, we investigated the influence of isoflurane, sevoflurane, and desflurane anesthesia on the profile of excitatory and inhibitory amino acids in the nucleus accumbens (NAcc) of alcohol-withdrawn rats (AWR). Methods Eighty Wistar rats were randomized into two groups of 40, pair-fed with alcoholic or non-alcoholic nutrition. Nutrition was withdrawn and microdialysis was performed to measure the activity of amino acids in the NAcc. The onset time of the withdrawal syndrome was first determined in an experiment with 20 rats. Sixty rats then received isoflurane, sevoflurane, or desflurane anesthesia for three hours during the withdrawal period, followed by one hour of elimination. Amino acid concentrations were measured using chromatography and results were compared to baseline levels measured prior to induction of anesthesia. Results Glutamate release increased in the alcohol group at five hours after the last alcohol intake (p = 0.002). After 140 min, desflurane anesthesia led to a lower release of glutamate (p < 0.001) and aspartate (p = 0.0007) in AWR compared to controls. GABA release under and after desflurane anesthesia was also significantly lower in AWR than controls (p = 0.023). Over the course of isoflurane anesthesia, arginine release decreased in AWR compared to controls (p < 0.001), and aspartate release increased after induction relative to controls (p20min = 0.015 and p40min = 0.006). However, amino acid levels did not differ between the groups as a result of sevoflurane anesthesia. Conclusions Each of three volatile anesthetics we studied showed different effects on excitatory and inhibitory amino acid concentrations. Under desflurane anesthesia, both glutamate and aspartate showed a tendency to be lower in AWR than controls over the whole timecourse. The inhibitory amino acid arginine increased in AWR compared to controls, whereas GABA levels decreased. However, there were no significant differences in amino acid concentrations under or after sevoflurane anesthesia. Under isoflurane, aspartate release increased in AWR following induction, and from 40 min to 140 min arginine release in controls was elevated. The precise mechanisms through which each of the volatile anesthetics affected amino acid concentrations are still unclear and further experimental research is required to draw reliable conclusions.

Little is known about the use of positive psychology interventions (PPI) in addictions treatment. Questionnaires and interviews with alcohol and substance use disorder counselors explored theories of how PPIs might work, the degree to which they are used, and downsides. Results suggested that positive and pathology-based themes were attended in equal proportion, that substance abuse treatment should help clients develop a good life in recovery; that counselors already use PPI; and that PPI might counter negative cognitions and affect. Reservations for using PPI included relying on PPI exclusively and employing PPI indiscriminately without regard to client characteristics.

Cognitive-behavioral treatments (CBT) are among the most popular interventions offered for alcohol and other substance use disorders, but it is not clear how they achieve their effects. CBT is purported to exert its beneficial effects by altering coping skills, but data supporting coping changes as the mechanism of action are mixed. The purpose of this pilot study was to test a treatment in which coping skills were trained in a highly individualized way, allowing us to determine if such training would result in an effective treatment. Participants were assigned randomly to a comprehensive packaged CBT program (PCBT), or to an individualized assessment and treatment program (IATP). The IATP program employed experience sampling via cellphone to assess coping skills prior to treatment, and provided therapists with a detailed understanding of patients' coping strengths and deficits. Out-patient treatment. A total of 110 alcohol-dependent men and women. Participants in both conditions completed experience sampling of situations, drinking and coping efforts prior to, and following, 12 weeks of treatment. Time-line follow-back procedures were also used to record drinking at baseline and post-treatment. IATP yielded higher proportion of days abstinent (PDA) at post-treatment (P < 0.05) than did PCBT, and equivalent heavy drinking days. IATP also elicited more momentary coping responses and less drinking in high-risk situations, as recorded by experience sampling at post-treatment. Post-treatment coping response rates were associated with decreases in drinking. The IATP approach was more successful than PCBT at training adaptive coping responses for use in situations presenting a high risk for drinking. The highly individualized IATP approach may prove to be an effective treatment strategy for alcohol-dependent patients.

The current study sought to evaluate the feasibility and efficacy of a brief mindfulness intervention aimed to reduce rates and consequences of binge drinking among college students. Participants were 76 undergraduate students assigned to a mindfulness/cue exposure group (MG) or a control/cue exposure only group (CG). Assessments were administered at the beginning of the initial session (i.e., baseline), the end of the initial session (i.e., posttreatment) and weekly for the subsequent 4 weeks. During the initial session, participants engaged in a cue exposure protocol that differed by group. The MG participated in a 60-min individual mindfulness intervention composed of didactic and experiential activities during the initial session. They participated in a mindfulness practice during the Week 2 follow-up assessment and were asked to engage in 1 hr of out-of-session mindfulness meditation each week during the 4-week assessment period. Treatment outcome examined changes in frequency of binge episodes, consequences of alcohol use, readiness to change alcohol use, alcohol refusal self-efficacy, and dispositional mindfulness between groups over time. Group differences in readiness to change, self-efficacy, and dispositional mindfulness were not found from baseline to posttreatment. Four weeks after the initial intervention, the MG reported significantly less binge episodes, fewer consequences of alcohol use, higherself-efficacy and higher dispositional mindfulness than the CG. Feasibility and participant acceptability of the intervention was demonstrated by consistent attendance, low attrition and high satisfaction ratings by the MG. Results provide initial support for the efficacy of a brief, mindfulness-based intervention among college students who report binge drinking.

There is a considerable body of evidence supporting the effectiveness of personalized feedback interventions for hazardous alcohol use-whether delivered face-to-face, by postal mail, or over the Internet (probably now the primary mode of delivery). The Check Your Drinking Screener (CYD; see www.CheckYourDrinking.net) is one such intervention. The current treatment dismantling study assessed which components of personalized feedback interventions were effective in motivating change in drinking. Specifically, the major objective of this project was to conduct a randomized controlled trial (RCT) comparing the impact of the normative feedback and other personalized feedback components of the CYD intervention in the general population. Participants were recruited to take part in an RCT and received either the complete CYD final report, just the normative feedback sections of the CYD, just the personalized feedback components of the CYD, or were assigned to a no-intervention control group. Participants were followed-up at 3 months to assess changes in alcohol consumption. A total of 741 hazardous drinking participants were recruited for the trial, of which 73 percent provided follow-up data. Analyses using an intent-to-treat approach found some evidence for the impact of the personalized feedback components of the CYD in reducing alcohol consumption on the variables, number of drinks in a week and AUDIT-C (p = .028 and .047 respectively; no impact on highest number of drinks on one occasion; p = .594). However, there was no significant evidence of the impact of the normative feedback components (all p > .3). Personalized feedback elements alone could provide an active intervention for hazardous drinkers, particularly in situations where normative feedback information was not available.

Aims Cognitive-behavioral treatments (CBT) are among the most popular interventions offered for alcohol and other substance use disorders, but it is not clear how they achieve their effects. CBT is purported to exert its beneficial effects by altering coping skills, but data supporting coping changes as the mechanism of action are mixed. The purpose of this pilot study was to test a treatment in which coping skills were trained in a highly individualized way, allowing us to determine if such training would result in an effective treatment. Design Participants were assigned randomly to a comprehensive packaged CBT program (PCBT), or to an Individualized Assessment and Treatment Program (IATP). The IATP program employed experience sampling via cellphone to assess coping skills prior to treatment, and provided therapists a detailed understanding of patients' coping strengths and deficits. Setting Outpatient treatment. Participants A total of 110 alcohol dependent men and women. Measurements Participants in both conditions completed experience sampling of situations, drinking and coping efforts prior to, and following, 12 weeks of treatment. Timeline follow-back procedures were also used to record drinking at baseline and posttreatment. Findings IATP yielded higher proportion days abstinent (PDA) at posttreatment (p < .05) than did PCBT, and equivalent heavy drinking days. IATP also elicited more momentary coping responses, and less drinking, in high risk situations, as recorded by experience sampling at posttreatment. Posttreatment coping response rates were associated with decreases in drinking. Conclusions The IATP approach was more successful than PCBT at training adaptive coping responses for use in situations presenting high-risk for drinking. The highly individualized IATP approach may prove to be an effective treatment strategy for alcohol dependent patients. PMID:19712124

The use of non-Saccharomyces strains in aerated conditions has proven effective for alcohol content reduction in wine during lab-scale fermentation. The process has been scaled up to 20 L batches, in order to produce lower alcohol wines amenable to sensory analysis. Sequential instead of simultaneous inoculation was chosen to prevent oxygen exposure of Saccharomyces cerevisiae during fermentation, since previous results indicated that this would result in increased acetic acid production. In addition, an adaptation step was included to facilitate non-Saccharomyces implantation in natural must. Wines elaborated with Torulaspora delbrueckii or Metschnikowia pulcherrima in aerated conditions contained less alcohol than control wine (S. cerevisiae, non-aerated). Sensory and aroma analysis revealed that the quality of mixed fermentations was affected by the high levels of some yeast amino acid related byproducts, which suggests that further progress requires a careful selection of non-Saccharomyces strains and the use of specific N-nutrients.

The objective of this project is to design, fabricate, and operate a fermentation facility which will demonstrate on a pilot-scale level (3 oven-dry tons (ODT) per day of feedstock) the economic and technical feasibility of producing anhydrous ethyl alcohol from lignocellulosic biomass residues (wood, corn stover, and wheat straw principally). The resultant process development unit (PDU) will be flexibly designed so as to evaluate current and projected unit operations, materials of construction, chemical and enzymatic systems which offer the potential of significant technological and economic breakthroughs in alcohol production from biomass. The principal focus of the project is to generatemore » fuels from biomass. As such, in addition to alcohol which can be used as a transportation fuel, by-products are to be directed where possible to fuel applications. The project consists of two parts: (1) conceptual design, and (2) detailed engineering design. The first quarter's activities have focused on a critical review of several aspects of the conceptual design of the 3 ODT/day PDU, viz.: (1) biomass cost, availability, and characterization; (2) pretreatment processes for lignocellulosic residues; (3) hydrolytic processes (enzymatic and acidic); (4) fermentation processes; (5) alcohol recovery systems; (6) by-product streams utilization; and (7) process economics.« less

Alcohol and hospitalized road traffic injuries in the Philippines.

O'Connor, Lydia R; Ruiz, Roberto Andres Llanes

2014-09-01

Each year, there are approximately 1.24 million deaths due to road traffic injuries, the majority of which occur in low- and middle-income countries. Since 2008, 35 countries have passed legislation to implement road safety strategies. However, many countries have yet to pass comprehensive legislation while others lack adequate enforcement of current policies. The annual global mortality rate due to road trauma remains unacceptably high and reflects the need for governments to prioritize the passage and implementation of road safety legislation. Alcohol is a leading risk factor for road trauma globally and the leading cause of death and disability in the Western Pacific region. Despite the overwhelming evidence that strict enforcement of drunk-driving policies can lead to a drastic reduction in alcohol-related road incidents, many countries in the Western Pacific lack sufficient data that could facilitate the design of appropriate drunk-driving interventions. This paper provides an analysis of the current status of policies and attitudes related to alcohol and road injuries throughout the Western Pacific region, with a specific focus on the Philippines. Following the passage of drunk-driving legislation in 2013, a medical records review of alcohol-related road trauma patients in Manila Doctors Hospital was conducted. The findings of this pilot project further highlight the pervasive problem of missing or unreliable data regarding alcohol's role in road trauma. Assessing the burden of drunk driving is an important step in designing effective interventions and systematically changing attitudes about driving under the influence.

Alcohol misuse is an important cause of premature disability and death. While clinicians are recommended to ask patients about alcohol use and provide brief interventions and specialist referral, this is poorly implemented in routine practice. We undertook a national consultation to ascertain the appropriateness of proposed standards for recording information about alcohol use in electronic health records (EHRs) in the UK and to identify potential barriers and facilitators to their implementation in practice. A wide range of stakeholders in the UK were consulted about the appropriateness of proposed information standards for recording alcohol use in EHRs via a multi-disciplinary stakeholder workshop and online survey. Responses to the survey were thematically analysed using the Consolidated Framework for Implementation Research. Thirty-one stakeholders participated in the workshop and 100 in the online survey. This included patients and carers, healthcare professionals, researchers, public health specialists, informaticians, and clinical information system suppliers. There was broad consensus that the Alcohol Use Disorders Identification Test (AUDIT) and AUDIT-Consumption (AUDIT-C) questionnaires were appropriate standards for recording alcohol use in EHRs but that the standards should also address interventions for alcohol misuse. Stakeholders reported a number of factors that might influence implementation of the standards, including having clear care pathways and an implementation guide, sharing information about alcohol use between health service providers, adequately resourcing the implementation process, integrating alcohol screening with existing clinical pathways, having good clinical information systems and IT infrastructure, providing financial incentives, having sufficient training for healthcare workers, and clinical leadership and engagement. Implementation of the standards would need to ensure patients are not stigmatised and that patient confidentiality is robustly maintained. A wide range of stakeholders agreed that use of AUDIT-C and AUDIT are appropriate standards for recording alcohol use in EHRs in addition to recording interventions for alcohol misuse. The findings of this consultation will be used to develop an appropriate information model and implementation guide. Further research is needed to pilot the standards in primary and secondary care.

Objectives Meditation is a promising treatment for alcohol dependence. This 16-week prospective case series was designed to gather preliminary data about the efficacy of meditation for relapse prevention and to evaluate study methods feasibility. Methods Nineteen adult alcohol-dependent graduates of an intensive outpatient program were enrolled. Fifteen subjects completed the 8-week meditation course supplemented by at-home meditation and “standard of care” therapy. Outcome measures included surveys and 2 stress-responsive biomarkers. Results Subjects (N = 19, 38.4 standard deviation [SD] = 8.6-year-old) were abstinent for 30.9 (SD = 22.2) days at enrollment. Completers (N = 15) attended 82% of meditation course sessions and meditated on average 4.6 (SD = 1.1) days per week; they were abstinent on 94.5% (SD = 7.4) of study days, with 47% reporting complete abstinence and 47% reporting 1 or more heavy drinking days. Their severity of depression, anxiety, stress (P < 0.05), and craving (P < 0.08), documented relapse triggers, decreased, and the degree of mindfulness increased (P < 0.05). The meditation course was rated as a “very important” (8.7/10, SD = 1.8) and “useful relapse prevention tool” (8.5/10, SD = 2.1); participants reported being “very likely” to continue meditating (9.0/10, SD = 1.5). “Gaining skills to reduce stress,” “coping with craving,” and “good group support” were the most common qualitative comments about the course value. Compared with baseline, at 16 weeks, interleukin-6 levels decreased (N = 12, P = 0.05); cortisol levels (N = 10) were reduced but not significantly. There were no adverse events or side effects. Conclusions Meditation may be an effective adjunctive therapy for relapse prevention in alcohol dependence, worthy of investigation in a larger trial. The study methods are appropriate for such a trial. PMID:21768988

Homeless young adults ages 18–25 exhibit high rates of alcohol and other drug (AOD) use, and sexual risk behaviors such as unprotected sex. Yet few programs exist for this population that are both effective and can be easily incorporated into settings serving this population. This pilot cluster cross-over randomized controlled trial evaluates AWARE, a voluntary four session group-based motivational interviewing (MI) intervention to reduce AOD use and sexual risk behavior. We evaluated AWARE with 200 homeless young adults using drop-in center services in Los Angeles County (mean age=21.8 years; 73% male; 79% heterosexual; 31% non-Hispanic White, 25% African American, 24% Hispanic, 21% multiracial/other). Surveys were completed at baseline and three months after program completion. Retention in the AWARE program was excellent (79% attended multiple sessions) and participants reported high levels of satisfaction with the program. AWARE participants self-reported positive change in their past 3 month and past 30 day alcohol use (ps ≤ .05), motivation to change drug use (ps < .05), and condom use self-efficacy (p = .05) compared to the control group. Among those with multiple sex partners, AWARE participants showed a decrease in unprotected sexual events (p < .05), whereas the control group did not. Results from this pilot evaluation are promising, suggesting that a brief group-MI risk reduction intervention can be effective in helping homeless young adults make positive changes in their alcohol and condom use. Further work is needed to more fully evaluate the efficacy of AWARE on AOD behavior and sexual risk behavior outcomes. PMID:28340904

Brief motivational intervention (MI) is an efficacious approach to reduce heavy drinking and associated sexual risk behavior among Emergency Department (ED) patients, but the intensity of demands placed on ED staff makes the implementation of in-person MIs logistically challenging. This proof-of-concept pilot study examined the acceptability and logistic feasibility of using video-conferencing technology to deliver an MI targeting heavy drinking and risky sexual behavior to patients in an ED setting. Rigorous screening procedures were employed to ensure that the pilot sample represents the target portion of ED patients who would benefit from this multi-target MI. Mixed qualitative and quantitative data from a sample of seven ED patients (57% Female; Mage = 35 years) who received MI by video conference consistently demonstrated high levels of satisfaction, engagement, and acceptability. The observed completion rate supports logistic feasibility, and patient feedback identified methods to improve the experience by using high-definition hardware, ensuring stronger network connectivity, and effectively communicating information regarding protection of privacy. Post-intervention patient ratings and independent ratings of the audio-recorded sessions (using the Motivational Interviewing Skills Coding system) were very high, suggesting that intervention fidelity and MI adherence was not compromised by delivery modality. Collectively, these data suggest video conferencing is a viable technology that can be employed to implement brief evidence-based MIs in ED settings. PMID:28649188

Introduction Behavioral couples therapy (BCT) has been found to improve long-term abstinence rates in alcohol- and substance-dependent populations but has not been tested for smoking cessation. This pilot study examined the feasibility and acceptability of BCT for smoking-discordant couples. Methods Forty-nine smokers (smoking >10 cigarettes/day) with non-smoking partners were randomized to receive a couples social support (BCT-S) intervention, or an individually-delivered smoking cessation (ST) treatment. The couples were married or cohabiting for at least one year, with partners who had never smoked or had not used tobacco in one year. Both treatments included seven weekly sessions and 8-weeks of nicotine replacement therapy. Participants were followed for six months post-treatment. The Partner Interaction Questionnaire (PIQ) was used to measure perceived smoking-specific partner support. Results Participants were 67% male and 88% White. Biochemically-verified cessation rates were 40.9%, 50% and 45% in BCT-S, and 59.1%, 50%, and 55% in ST, at end of treatment, 3-, and 6-months, respectively, and did not differ significantly between treatment conditions at any time point (all p’s > .05). Perceived smoking-specific partner support at post-treatment did not significantly differ between treatment groups (M=2.45, SD .81 in BCT-S; M=2.27, SD .92 in ST; t(38) = .67, p = .51). Conclusions Results of this pilot study do not provide support for the efficacy of BCT in smoking discordant couples. PMID:25642582

A lesson program for schoolchildren about a clean and healthy life-style: a pilot study.

A health education project is underway in primary schools in the Wonogiri district of Indonesia. This project, implemented by the Yayasan Indonesia Sejahtera (YIS), is related to the Perilaku Hidup Bersih dan Sehat (PHBS) campaign developed by the Provincial Health Office of central Java to promote a healthy life-style. The PHBS campaign, which will eventually target households, industry, and schools, is currently promoting only 10 household-level indicators. Thus, YIS developed a curriculum for PHBS that includes those indicators that are relevant to primary school students. The longterm YIS project group includes the fifth-grade (11- and 12-year-old students) at every elementary school in the district. A single class in a village school is serving as the target group for the pilot study. Development of the pilot curriculum involved a pre/post test as well as a field test, and an evaluation is planned. The health topics chosen for the project are: clean water, use of family sanitation facilities, garbage disposal, mosquitoes, personal hygiene, dental hygiene, nutrition, smoking and alcohol, and family planning. The curriculum consists of seven lessons and is taught using visual aids and a participatory approach. Post-test results were disappointing because answers improved over pretest answers for only 5 out of 21 questions. One of the reasons may have been that the project had to begin before all of the supporting materials were ready. Evaluation is currently ongoing, and plans are underway to expand the program.

We studied 13 U.S. male military veterans and their female partners who consented to participate in an uncontrolled trial of couple treatment for alcohol use disorder and posttraumatic stress disorder (CTAP). CTAP is a 15-session, manualized therapy, integrating behavioral couples therapy for alcohol use disorder (AUD) with cognitive-behavioral conjoint therapy for posttraumatic stress disorder (PTSD). Due to ineligibility (n = 1) and attrition (n = 3), 9 couples completed the study, and 7 completed 12 or more sessions. There were 8 veterans who showed clinically reliable pre- to posttreatment reduction of PTSD outcomes. There were also significant group-level reductions in clinician-, veteran-, and partner-rated PTSD symptoms (d = 0.94 to 1.71). Most veterans showed clinically reliable reductions in percentage days of heavy drinking. Group-level reduction in veterans' percentage days of heavy drinking was significant (d = 1.01). There were 4 veterans and 3 partners with clinically reliable reductions in depression, and group-level change was significant for veterans (d = 0.93) and partners (d = 1.06). On relationship satisfaction, 3 veterans and 4 partners had reliable improvements, and 2 veterans and 1 partner had reliable deterioration. Group-level findings were nonsignificant for veteran relationship satisfaction (d = 0.26) and for partners (d = 0.52). These findings indicate that CTAP may be a promising intervention for individuals with comorbid PTSD and AUD who have relationship partners.

NC-TEST: noncontact thermal emissions screening technique for drug and alcohol detection

NASA Astrophysics Data System (ADS)

Prokoski, Francine J.

1997-01-01

Drug abuse is highly correlated with criminal behavior. The typical drug-using criminal commits hundreds of crimes per year. The crime rate cannot be significantly reduced without a reduction in the percentage of the population abusing drugs and alcohol. Accurate and timely estimation of that percentage is important for policy decisions concerning crime control, public health measures, allocation of intervention resources for prevention and treatment, projections of criminal justice needs, and the evaluation of policy effectiveness. Such estimation is particularly difficult because self reporting is unreliable; and physical testing has to date required blood or urine analysis which is expensive and invasive, with the result that too few people are tested. MIKOS Ltd. has developed a non-contact, passive technique with the potential for automatic, real- time screening for drug and alcohol use. The system utilizes thermal radiation which is spontaneously and continuously emitted by the human body. Facial thermal patterns and changes in patterns are correlated with standardized effects of specific drugs and alcohol. A portable system incorporating the collection and analysis technique can be used episodically to collect data for estimating drug and alcohol use by general unknown populations such as crowds at airports, or it can be used for repetitive routine screening of specific known groups such as airline pilots, military personnel, school children, or persons on probation or parole.

An Introduction to Body Vandalism: What is it? Who does it? When does it happen?

A number of typical consequences for alcohol and other substances have been well documented. However, a specific category of consequences which has received no attention in the existing literature includes acts (other than sexual assault) committed upon incapacitated individuals. We have termed this behavior Body Vandalism (BV), defined as the direct manipulation of an incapacitated individual through the addition of markings, objects or substances, removal of property or hair, or relocation of a body. The purpose of this paper is to provide a preliminary examination of rates of experiencing and variations in positive and negative perceptions of this behavior from victim's perspective. A pilot study was conducted aimed at examining the rates and demographic characteristics of body vandalism in a national sample of 981 adults. The majority of individuals had witnessed BV, half had perpetrated, and over 40% had been a victim in their lifetime. Rates of lifetime victimization and perpetration were low (1-2 times). Perpetrators most often targeted their friends and alcohol was typically a factor in victimization. Over half of victims reported experiencing positive social outcomes as a result of being victimized and about a third reported negative emotional outcomes. Findings suggest that experiences of body vandalism are relatively common, especially in young adults, associated with alcohol consumption, and result in both positive and negative outcomes for victims. This study offers evidence for BV as an outcome of social drinking, suggests contexts that increase the risk of BV occurrence, and provides a foundation from which future studies can build.

Aims: Long-term heavy use of cannabis and alcohol are known to be associated with memory impairments. In this study, we used event-related potentials to examine verbal learning and memory processing in a commonly used behavioral task. Method: We conducted two studies: first, a small pilot study of adolescent males, comprising 13 Drug-Naive Controls (DNC), 12 heavy drinkers (HD) and 8 cannabis users (CU). Second, a larger study of young adults, comprising 45 DNC (20 female), 39 HD (16 female), and 20 CU (9 female). In both studies, participants completed a modified verbal learning task (the Rey Auditory Verbal Learning Test, RAVLT) while brain electrical activity was recorded. ERPs were calculated for words which were subsequently remembered vs. those which were not remembered, and for presentations of learnt words, previously seen words, and new words in a subsequent recognition test. Pre-planned principal components analyses (PCA) were used to quantify the ERP components in these recall and recognition phases separately for each study. Results: Memory performance overall was slightly lower than published norms using the standardized RAVLT delivery, but was generally similar and showed the expected changes over trials. Few differences in performance were observed between groups; a notable exception was markedly poorer delayed recall in HD relative to DNC (Study 2). PCA identified components expected from prior research using other memory tasks. At encoding, there were no between-group differences in the usual P2 recall effect (larger for recalled than not-recalled words). However, alcohol-related differences were observed in a larger P540 (indexing recollection) in HD than DNC, and cannabis-related differences were observed in a smaller N340 (indexing familiarity) and a lack of previously seen > new words effect for P540 in Study 2. Conclusions: This study is the first examination of ERPs in the RAVLT in healthy control participants, as well as substance-using individuals, and represents an important advance in methodology. The results indicate alterations in recognition memory processing, which even if not manifesting in overt behavioral impairment, underline the potential for brain dysfunction with early exposure to alcohol and cannabis.

Absence of successful transition to post-detoxification treatment leads to high rates of relapse among detoxified heroin users. The present study evaluated a pilot buprenorphine treatment program (BTP). Heroin dependent individuals were inducted onto buprenorphine/naloxone in detox, maintained while transitioning through an intensive inpatient program (IIP), and gradually tapered off medication over 5 months of outpatient (OP) treatment. Compared to programmatic indicators of treatment engagement in the year prior to BTP implementation, referrals from detox to IIP, entry into and completion of IIP and subsequent OP, and days in OP treatment increased substantially. BTP completers, compared to non-completers, viewed abstinence as more difficult and as requiring more assistance to achieve, were less likely to be current cocaine and alcohol users or to have relapsed during the course of treatment. Although preliminary and in need of replication, initial adjunctive use of buprenorphine in an abstinence-based continuum of care may improve post-detoxification treatment entry, engagement, and completion.

It is well established that in both food- and drug-addicted individuals, there is dopamine resistance due to an association with the DRD2 gene A1 allele. Evidence is emerging whereby the potential of utilizing a natural, nonaddicting, safe, putative D2 agonist may find its place in recovery from reward deficiency syndrome (RDS) in patients addicted to psychoactive chemicals. Utilizing quantitative electroencephalography (qEEG) as an imaging tool, we show the impact of Synaptamine Complex Variant KB220™ as a putative activator of the mesolimbic system. We demonstrate for the first time that its intravenous administration reduces or "normalizes" aberrant electrophysiological parameters of the reward circuitry site. For this pilot study, we report that the qEEGs of an alcoholic and a heroin abuser with existing abnormalities (ie, widespread theta and widespread alpha activity, respectively) during protracted abstinence are significantly normalized by the administration of 1 intravenous dose of Synaptamine Complex Variant KB220™. Both patients were genotyped for a number of neurotransmitter reward genes to determine to what extent they carry putative dopaminergic risk alleles that may predispose them for alcohol or heroin dependence, respectively. The genes tested included the dopamine transporter (DAT1, locus symbol SLC6A3), dopamine D4 receptor exon 3 VNTR (DRD4), DRD2 TaqIA (rs1800497), COMT val158 met SNP (rs4680), monoamine oxidase A upstream VNTR (MAOA-uVNTR), and serotonin transporter-linked polymorphic region (5HTTLPR, locus symbol SLC6A4). We emphasize that these are case studies, and it would be unlikely for all individuals to carry all putative risk alleles. Based on previous research and our qEEG studies (parts 1 and 2 of this study), we cautiously suggest that long-term activation of dopaminergic receptors (ie, DRD2 receptors) will result in their proliferation and lead to enhanced "dopamine sensitivity" and an increased sense of happiness, particularly in carriers of the DRD2 A1 allele. This is supported by a clinical trial on Synaptamine Complex Variant KB220™ using intravenous administration in > 600 alcoholic patients, resulting in significant reductions in RDS behaviors. It is also confirmed by the expanded oral study on Synaptose Complex KB220Z™, published as part 2 of this study. Future studies must await both functional magnetic resonance imaging and positron emission tomography scanning to determine the acute and chronic effects of oral KB220™ on numbers of D2 receptors and direct interaction at the nucleus accumbens. Confirmation of these results in large, population-based, case-controlled experiments is necessary. These studies would provide important information that could ultimately lead to significant improvement in recovery for those with RDS and dopamine deficiency as a result of a multiple neurotransmitter signal transduction breakdown in the brain reward cascade.

Six lessons from state physician health programs to promote long-term recovery.

Dupont, Robert L; Skipper, Gregory E

2012-01-01

The success of the nation's state physician health programs (PHPs) provides important new evidence on the potential for dramatically reducing relapse and promoting long-term recovery from substance use disorders. This article summarizes the findings of the first national PHP study and outlines six lessons learned from this model of care management: (1) zero tolerance for any use of alcohol and other drugs; (2) thorough evaluation and patient-focused care; (3) prolonged, frequent random testing for both alcohol and other drugs; (4) effective use of leverage; (5) defining and managing relapses; and (6) the goal of lifelong recovery rooted in the 12-Step fellowships. PHPs are a part of a new paradigm of care management that includes the programs developed for commercial pilots (HIMS) and for attorneys (CoLAP). Elements of this model of care have been used with a dramatically different patient population, and with similar success, in the criminal justice system in HOPE Probation and 24/7 Sobriety. The authors review these programs and discuss implications for extending elements of the new paradigm more widely.

Managed alcohol programmes (MAP) are a harm reduction strategy used to minimise the personal harm and adverse societal effects that alcohol dependence can lead to by providing an alternative to zero-tolerance approaches that incorporate drinking goals (abstinence or moderation) that are compatible with the needs of the individual, and promoting access to services by offering low-threshold alternatives. This enables clients to gain access to services despite continued alcohol consumption and works to help the patient understand the risks involved in their behaviour and make decisions about their own treatment goals. To assess the effectiveness of MAP treatment regimens (serving limited quantities of alcohol daily to alcoholics) on their own or as compared to moderate drinking (self-controlled drinking), screening and brief intervention using a harm reduction approach, traditional abstinence-based interventions (12 step programmes) and no intervention. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL and PsycINFO up to March 2012. This search was expanded by handsearching of high-yield journals and conference proceedings that had not already been handsearched on behalf of The Cochrane Collaboration, searching reference lists of all papers and relevant reviews identified, references to ongoing and recently completed clinical trials in the National Research Register and IFPMA Clinical Trials Database (which contains ClinicalTrials.gov, Centerwatch, Current Controlled Trials and ClinicalStudyResults.gov, and Osservatorio Nazionale sulla Sperimentazione Clinica dei Medicinali). Trials registers, grey literature and reference lists were also searched. Individuals, organisations and experts in the field were contacted. Randomised control trials (RCT), controlled clinical trials (CCT), interrupted time series (ITS) studies, and control before and after (CBA) studies involving vulnerable people aged 18 years or older who were at high risk for alcohol abuse attending MAP, defined as a structured programme that provided clients with controlled amounts of alcohol on a daily schedule, comparing no treatment, moderate drinking, brief intervention or 12-step variants. All study citations were collated into a single database. Two review author independently screened titles and abstracts and selected references potentially relevant to the review. Differences between selection lists were resolved by discussion. Two review authors independently evaluated whether studies should be included or excluded according to the eligibility criteria. In the event of a disagreement, a third author was consulted. No studies were included in the review. This systematic review was intended to assess the effectiveness of a brief MAP on the reduction of incidence of harmful behaviour; however, no evidence was available to make this comparison; 22 articles were considered possibly relevant and all were excluded. Most articles were excluded because they failed to compare or consider managed alcohol as the experimental or control intervention, as well as one study (Baker 2010), which was also excluded because study participants were under 18 years of age. No study reviewed offered an intervention that was compared with managed alcohol or considered it as the intervention of interest, providing insufficient evidence to address the objectives of the review. Four studies (Aalto 2001; Baker 2010; Bertholet 2005; Tracy 2007) considered alcohol reduction as an outcome of interest, while four engaged interventions in a shelter setting or targeted vulnerable people (Baker 2010; Bradford 2005; Lapham 1993; McGlynn 1993); only one study (Kidd 2011) offered a qualitative assessment of a participant being admitted to MAP, but offered no analysis of the programme itself. These results accurately reflect the use of MAPs in current practice as existing programmes are ongoing only in a small number of sample pilot projects that target individuals with severe alcohol dependence or who consume non-beverage alcohol. The lack of evidence does not allow for a conclusion regarding the efficacy of MAP on their own, or as compared to brief intervention, moderate drinking, no intervention or 12-step variants. It is the review authors' opinion that it is likely to be the objective of MAPs that reduce their reportability and use in current practice, rather than a failure to provide an intervention that reduces the effects of alcohol dependence. Aiming to reduce harmful or antisocial behaviour in vulnerable individuals through the regulation of daily alcohol intake, rather than reducing harmful alcohol intake over time, provides considerable difficulty in developing measures of success from self-reported data (low treatment thresholds), monitoring long-term efficacy or establishing causal links between programme admission and a reduction in targeted behaviours, owing to the fact that prolonged participation in the programme is likely to indicate a willingness in the individual to change their behaviour patterns. More effort is needed to develop reporting measures, as well as methodologies, which address these specific challenges.

To date, placebo-controlled drug trials targeting the core social impairment of autistic disorder (autism) have had uniformly negative results. Given this, the search for new potentially novel agents targeting the core social impairment of autism continues. Acamprosate is U.S. Food and Drug Administration-approved drug to treat alcohol dependence. The drug likely impacts both gamma-aminobutyric acid and glutamate neurotransmission. This study describes our initial open-label experience with acamprosate targeting social impairment in youth with autism. In this naturalistic report, five of six youth (mean age, 9.5 years) were judged treatment responders to acamprosate (mean dose 1,110 mg/day) over 10 to 30 weeks (mean duration, 20 weeks) of treatment. Acamprosate was well tolerated with only mild gastrointestinal adverse effects noted in three (50%) subjects.

Gut microbial dysbiosis is implicated in the pathogenesis of non-alcoholic steatohepatitis (NASH). We investigated downstream effects of gut microbiota modulation on markers of hepatic inflammation, steatosis, and hepatic and peripheral insulin sensitivity in patients with NASH using rifaximin therapy. Patients with biopsy-proven NASH and elevated aminotransferase values were included in this open-label pilot study, all receiving 6 weeks rifaximin 400 mg twice daily, followed by a 6-week observation period. The primary endpoint was change in alanine aminotransferase (ALT) after 6 weeks of rifaximin. Secondary endpoints were change in hepatic lipid content and insulin sensitivity measured with a hyperinsulinemic-euglycemic clamp. Fifteen patients (13 men and 2 women) with a median (range) age of 46 (32-63) years were included. Seven had diabetes on oral hypoglycemic medications and 8 had no diabetes. After 6 weeks of therapy, no differences were seen in ALT (55 [33-191] vs. 63 [41-218] IU/L, P = 0.41), peripheral glucose uptake (28.9 [19.4-48.3] to 25.5 [17.7-47.9] μmol/kg/min, P = 0.30), hepatic insulin sensitivity (35.2 [15.3-51.7]% vs. 30.0 [10.8-50.5]%, P = 0.47), or hepatic lipid content (21.6 [2.2-46.2]% vs. 24.8 [1.7-59.3]%, P = 0.59) before and after rifaximin treatment. After 12 weeks from baseline, serum ALT increased to 83 (30-217) IU/L, P = 0.02. There was a significant increase in the homeostasis model assessment-estimated insulin resistance index (P = 0.05). The urinary metabolic profile indicated a significant reduction in urinary hippurate with treatment, which reverted to baseline after cessation of rifaximin, although there was no consistent difference in relative abundance of fecal microbiota with treatment. These data do not indicate a beneficial effect of rifaximin in patients with NASH. © 2017 The Japan Society of Hepatology.

To assess the feasibility of conducting a cost-effectiveness study of using care farms (CFs) to improve quality of life and reduce reoffending among offenders undertaking community orders (COs). To pilot questionnaires to assess quality of life, connection to nature, lifestyle behaviours, health and social-care use. To assess recruitment and retention at 6 months and feasibility of data linkage to Police National Computer (PNC) reconvictions data and data held by probation services. Pilot study using questionnaires to assess quality of life, individually linked to police and probation data. The pilot study was conducted in three probation service regions in England. Each site included a CF and at least one comparator CO project. CFs are working farms used with a range of clients, including offenders, for therapeutic purposes. The three CFs included one aquaponics and horticulture social enterprise, a religious charity focusing on horticulture and a family-run cattle farm. Comparator projects included sorting secondhand clothes and activities to address alcohol misuse and anger management. We recruited 134 adults (over 18) serving COs in England, 29% female. 52% of participants completed follow-up questionnaires. Privatisation of UK probation trusts in 2014 negatively impacted on recruitment and retention. Linkage to PNC data was a more successful means of follow-up, with 90% consenting to access their probation and PNC data. Collection of health and social-care costs and quality-adjusted life year derivation were feasible. Propensity score adjustment provided a viable comparison method despite differences between comparators. We found worse health and higher reoffending risk among CF participants due to allocation of challenging offenders to CFs, making risk of reoffending a confounder. Recruitment would be feasible in a more stable probation environment. Follow-up was challenging; however, assessing reconvictions from PNC data is feasible and a potential primary outcome for future studies. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Interventions for alcohol use disorders (AUDs) in HIV infected individuals have been primarily targeted at HIV risk reduction and improved antiretroviral treatment adherence. However, reduction in alcohol use is an important goal. Alcohol use affects other key factors that may influence treatment course and outcome. In this study the authors aim to administer an adapted intervention for AUDs to reduce alcohol use in people living with HIV/AIDS (PLWHA). This study is a cluster randomised controlled trial at 16 HIV care clinics. A motivational interviewing and cognitive behavioural therapy based intervention for AUDs, developed through adaptation and piloted in Zimbabwe, will be administered to PLWHA with AUDs recruited at HIV clinics. The intervention will be administered over 16 sessions at 8 HIV clinics. This intervention will be compared with an equal attention control in the form of the World Health Organization Mental Health Gap Action Programme (WHO mhGAP) guide, adapted for the Zimbabwean context. General function, quality of life, and adherence to highly active antiretroviral treatment (HAART) will be secondary outcomes. Booster sessions will be administered to both groups at 3 and 6 months respectively. The primary outcome measure will be the Alcohol Use Disorder Identification Test (AUDIT) score. The World Health Organisation Disability Assessment Schedule 2.0 (WHODAS 2.0), World Health Organisation Quality of Life (WHOQoL) HIV, viral load, and CD4 counts will be secondary outcome measures. Outcome assessments will be administered at baseline, 3, 6, and 12 months. Moderating factors such as perceived social support, how people cope with difficult situations and post-traumatic exposure and experience will be assessed at baseline. Trained research assistants will recruit participants. The outcome assessors who will be trained in administering the outcome and moderating tools will be blinded to the treatment arms allocated to the participants. However, the principal investigator, participants and intervention staff will be unblinded. Data will be analysed using STATA Version 14. Primary and secondary outcomes will be measured at four time points that is; at baseline, 3, 6, and 12 months respectively. All participants will be included in the analysis of primary and secondary outcome measures. The mean AUDIT scores will be compared between groups using student t-tests. Multilevel logistic regression analysis will be performed for binominal variables and multilevel linear regression for continuous variables. Descriptive statistics will be computed for baseline and follow-up assessments. The study will be the first to address problematic alcohol use in PLWHA in Zimbabwe. It seeks to use local resources in delivering a modified, brief, evidence-based, and culturally contextualised intervention. The study results will determine the effectiveness of adapting psychological interventions for AUDs in HIV infected adults using a task-sharing framework.

A high proportion of persons convicted of driving while impaired repeat the offense. Many continue drinking and driving, even when faced with long jail terms. Hence, they pose a serious public health threat. This preliminary study evaluated extended-release, injectable naltrexone suspension (XR-NTX) and supportive therapy in reducing (1) drinking and (2) attempts to drive after drinking among repeat driving while impaired offenders with an ignition interlock device installed in their vehicles. Treatment-seeking volunteers received medical management therapy and 3 monthly injections of XR-NTX. We compared data on alcohol consumption, alcohol biomarkers, and interlock information before, during, and after treatment using summary measures and Sign tests. Of 12 consented subjects, 10 received at least 1 injection, and 7 received all 3 injections. All subjects receiving medication reported a decrease in average drinks per day (P < 0.01) and abstinent days (P = 0.02) while on treatment versus pretreatment levels. Average daily drinks decreased by 77%, from 3.0 to 0.69 (P < 0.01), during treatment with XR-NTX. Average drinks per drinking day also declined by 39% during treatment, from 6.6 to 4.0 (P = 0.04). Percent days abstinent increased by 31%, from 56.8 to 81.96 (P = 0.02), which persisted after treatment completion. Biomarkers were consistent with reduced drinking. The percentage of vehicular failures to start due to elevated breath alcohol decreased from 3.1% of tests to 1.29% of tests. A randomized, controlled clinical trial is needed to demonstrate the efficacy of this promising treatment regimen for repeat offenders.

The need to develop effective and accessible interventions for suicidal individuals engaging in heavy episodic drinking (HED) cannot be understated. While the link between alcohol use and suicidality is a complex one that remains to be elucidated, emotion dysregulation may play a key role in alcohol-related suicide risk in these individuals. In the current study, an 8-week Internet-delivered dialectical behavior therapy (DBT) skills training intervention was developed and preliminarily evaluated for suicidal individuals who engage in HED to regulate emotions. The aim of the study is to evaluate the feasibility and effectiveness of the therapist-assisted and Internet-delivered intervention, and to inform the design of a subsequent full-scale study. The study was a pilot randomized controlled trial comparing participants receiving immediate-treatment (n=30) to waitlist controls (n=29) over a period of 16 weeks. Intervention effects will be assessed longitudinally using hierarchical linear modeling and generalized estimating equations, along with analyses of effect sizes and clinically significant change. The primary outcomes are suicidal ideation, alcohol problems, and emotion dysregulation. Secondary outcomes include alcohol-related consequences, reasons for living, skills use, and depression. The trial is ongoing. A total of 60 individuals returned their informed consent and were randomized, of whom 59 individuals were intended to treat. A total of 50 participants in the study were retained through the 16-week enrollment. There is a dearth of evidence-based treatment for individuals presenting with high risk and complex behaviors. Furthermore, computerized interventions may provide a beneficial alternative to traditional therapies. The particular clinical features and treatment needs of suicidal individuals who also engage in HED constitute key domains for further investigation that are needed to consolidate the design of appropriate interventions for this high-risk population.

Ecological momentary assessments (EMA) are data collection approaches that characterize behaviors in real-time. However, EMA is underutilized in alcohol and substance use research among men who have sex with men (MSM). The aim of this analysis is to explore the correlates of engagement in EMA text messages among substance-using MSM in San Francisco. The present analysis uses data collected from the Project iN pilot study (n=30). Over a two-month period, participants received and responded to EMA daily text messages inquiring about their study medication, alcohol, and methamphetamine use. Baseline characteristics including demographics, alcohol use, and substance use were examined as potential correlates of engagement in EMA text messages in logistic regression and proportional hazards models. Participants had a 74% response rate to EMA text messages over the study period. MSM of color had significantly lower adjusted odds of responding to EMA texts 80% of the time or more, compared to white MSM (adjusted odds ratio=0.05, 95%CI=0.01-0.38). College-educated MSM had a lower adjusted hazard of week-long discontinuation in EMA texts (adjusted hazard ratio=0.12, 95%CI=0.02-0.63). Older MSM had a higher adjusted hazard of week-long discontinuation in EMA texts (adjusted hazard ratio=1.15, 95%CI=1.01-1.31). Differences in engagement in EMA text prompts were discovered for MSM with different racial/ethnic backgrounds, ages, and education levels. Substance use variables were not correlated with engagement in text messages, suggesting that EMA may be a useful research tool among actively substance-using MSM in San Francisco.

The aim of this study was to compare the effectiveness of a brief and an intensive self-help alcohol intervention and to assess the feasibility of recruiting to such interventions in a workplace setting. Employees who screened positive for hazardous drinking (n = 85) received online personalized normative feedback and were randomly assigned to one out of two conditions: either they received an e-booklet about the effects of alcohol or they received a self-help intervention comprising 62 web-based, fully automated, and interactive sessions, plus reminder e-mails, and mobile phone text messages (Short Message Service). Two months after baseline, the responders in the intensive condition drank an average of five to six drinks less per week compared to the responders in the brief condition (B = 5.68, 95% CI = 0.48-10.87, P = .03). There was no significant difference between conditions, using baseline observation carried forward imputation (B = 2.96, 95% CI = -0.50-6.42, P = .09). Six months after baseline, no significant difference was found, neither based on complete cases nor intent-to-treat (B = 1.07, 95% CI = -1.29-3.44, P = .37). Challenges with recruitment are thoroughly reported. The study supports the feasibility and the safety of use for both brief and intensive Internet-based self-help in an occupational setting. The study may inform future trials, but due to recruitment problems and low statistical power, the findings are inconclusive in terms of the intensive program being more effective than brief intervention alone.

Improving substance use prevention efforts with executive function training.

Pentz, Mary Ann; Riggs, Nathaniel R; Warren, Christopher M

Executive function (EF) includes emotional regulation, planning and decision-making, and behavioral impulse control. Improving youth substance use (SU) prevention by targeting EF poses challenges including determining whether specific sub-domains of EF are more associated with SU than others, whether EF is related to some types of SU more than others, and whether EF programs might be enhanced by inclusion of mindfulness training. Data were drawn from two studies from the Pathways to Health project: a randomized controlled trial of 4th-6th graders and a cross-sectional pilot study of the relationship of EF to specific types of SU in a sample of 7th graders. Survey measures included assessment of the EF subdomains of inhibitory control (IC), emotional control, working memory, organization/planning, lifetime SU (tobacco and alcohol use), and mindfulness. Analyses included multivariate and multiple group path analysis. Results suggested that the EF sub-domain of IC was the strongest and most consistent predictor of SU, particularly cigarette and e-cigarette use, though emotional control was predictive of alcohol use among late-elementary school students. In the 7th grade sample, IC was predictive of alcohol, cigarette, and e-cigarette use only among students in the low 75% of mindfulness. Findings from the present studies suggest that improvements in SU prevention efforts may result from increased curricular emphasis on IC and its application to multiple substance use prevention, and systematically integrating mindfulness with EF skills training. Future research should examine whether EF-SU relationships vary across patterns of SU and types of measures used to assess EF. Copyright © 2016 The Authors. Published by Elsevier Ireland Ltd..

The development of a brief self-report questionnaire to measure 'recent' rash impulsivity: a preliminary investigation of its validity and association with recent alcohol consumption.

PubMed

Mayhew, Matthew J; Powell, Jane H

Traditionally, impulsivity has been regarded as a stable trait. However, a series of longitudinal and behavioural laboratory studies has found that impulsivity can fluctuate within individuals, suggesting that it has a state as well as a trait manifestation. Whilst existing impulsivity questionnaires tap the former, there is no self-report instrument to assess recent fluctuations in impulsivity. Research aims and design The present study set out to develop and undertake preliminary validation of a measure of 'recent' impulsivity, focusing in particular on Rash Impulsivity. Part of the construct validation of the resulting Recent Rash Impulsivity Scale (RRIS) entailed examining its association with recent alcohol intake, since there are well-documented reciprocal relationships between alcohol consumption and inhibitory control. In developing the RRIS, items from existing trait impulsivity questionnaires were converted into a 'previous two weeks' format. The pilot RRIS was then administered, along with a parallel trait version (Trait Rash Impulsivity Scale; TRIS) and a well-established trait impulsivity measure (the BIS-11; Patton, Stanford & Barratt, 1995), to two cohorts of first-year undergraduates aged 17 to 25 (N=240), on two occasions one month apart. Information about habitual and recent alcohol intake was also gathered. Factor analyses on both the RRIS and TRIS identified two factors: 'Cognitive Impulsivity' (CogImp) and 'Motor Impulsivity' (MotImp). Consistent with the RRIS being sensitive to fluctuations in impulsivity, it was found that, as predicted: i) the RRIS was somewhat less strongly correlated than the TRIS with an established trait measure (the BIS-11; Patton et al., 1995); ii) the test-retest stability of 'Total' scores (CogImp and MotImp) was weaker for the RRIS than the TRIS; iii) there was evidence that the RRIS MotImp and Total scales were more strongly predicted by recent alcohol intake than were their trait equivalents; and iv) the RRIS CogImp and Total scales correlated more strongly with their trait equivalents in participants whose alcohol consumption had remained stable recently (relative to their habitual intake), compared to those whose consumption had recently changed. These data suggest that transient changes in impulsivity can be assessed via self-report, and that the RRIS is sensitive to recent changes in alcohol intake. Subject to a more intensive and detailed validation, it is thus promising as a tool for tapping and characterising fluctuations in behavioural control and for exploring a range of factors to which this might be associated.

An evaluation of the Swedish ignition interlock program.

Bjerre, Bo

2003-01-01

The Swedish alcohol ignition interlock program for driving while intoxicated (DWI) offenders, both first-time as well as multiple offenders, was launched as a pilot project in 1999. It is a volunteer program and differs in some respects from other programs: It covers a period of 2 years, it includes very strict medical regulations entailing regular checkups by a physician, it does not require a prior period of hard suspension, and it focuses strongly on changes in alcohol habits. Records from the 5 years prior to the offence showed that DWI offenders are generally in a high-risk category long before their offense, with a four to five times higher accident rate (road accidents reported by the police) and a three to four times higher rate of hospitalization due to a road accident. Only 12% of the eligible DWI offenders took part in the program and, of these, 60% could be diagnosed as alcohol dependent or alcohol abusers. During the program, alcohol consumption is monitored through self-esteem questionnaires (AUDIT) and five different biological markers. Our data show a noticeable reduction in alcohol consumption among the interlock users. This, combined with the high rate of compliance with the regulations, probably accounts for the fact that there was no case of recidivism during the program. Preliminary findings also suggest a reduction in the annual accident rate for interlock users while in the program. It still is too early to draw any conclusions concerning the rate of recidivism after completion of the program due to an insufficient amount of data for analysis. Nevertheless, the preliminary results are so promising that the program will now be expanded to cover all of Sweden as well as to include all driver's license categories.

Phosphatidylethanol (PEth) can be detected in blood from 14 to as many as 28 days after alcohol consumption, depending on the amount and frequency of alcohol consumed. PEth may have utility for verifying abstinence in a contingency management (CM) intervention for alcohol use, particularly in settings where frequent verification of abstinence is impossible or impractical. Five nontreatment-seeking heavy drinkers (40% men) participated in an 11-week, ABA-phased within-subject experiment for which they submitted blood spots for PEth measurement, urine samples for ethyl glucuronide (EtG) testing, and self-report drinking data weekly. Participants received reinforcers for submitting samples throughout the A phases. During the B phase (CM phase), they received additional reinforcers when their PEth level was reduced from the previous week and was verified by a negative EtG (<150 ng/ml) urine test and self-report. PEth, EtG, and self-report outcomes were compared between A phases (Weeks 1–3, 8–11) and B phases (Weeks 4–7). During the A phases, 23% of PEth results indicated alcohol abstinence, whereas 53% of PEth samples submitted during the CM (B phase) indicated alcohol abstinence. Participants were more likely to submit EtG-negative urine samples and report lower levels of drinking and heavy drinking during the B phase, relative to the A phases. We also explored the ability of PEth to detect self-reported drinking. The combined PEth homologs (16:0/18:1 and 16:0/18:2) predicted self-reported drinking with area under the curve from 0.81 (1 week) to 0.80 (3 weeks). Results support the initial feasibility of a Peth-based CM intervention. PMID:28714726

A pilot study was conducted to assess the performance of a municipal wastewater reclamation plant consisting of a combined coagulation-disk filtration (CC-DF) process, microfiltration (MF) and reverse osmosis (RO) membranes, in terms of the removal of water contaminants and changes in characteristics of effluent organic matter (EfOM). The CC-DF and MF membranes were not effective for the removal of dissolved water contaminants. However, they could partially reduce the turbidity associated with the cake layer formation by particulate materials on the membrane surfaces. Furthermore, most of water contaminants were completely removed by the RO membranes. Although the CC-DF process could remove approximately 20% of turbidity, the aluminium concentrations considerably increased after the CC-DF process due to the residual coagulants complexed with both carboxylic acid and alcohol functional groups of EfOM. Those aluminium-EfOM complexes had a lower negative charge and higher molecular weight (>0.1 μm pore size of the MF membranes) compared to non-complexed EfOM. These results indicate that the control of the formation of the aluminium-EfOM complexes should be considered as a key step to use the CC-DF process as a pre-treatment of the MF and RO membranes for mitigation of membrane fouling in the tested pilot plant.

Acetaldehyde is the first metabolite of ethanol and is produced in the epithelium by mucosal ALDH, while higher levels are derived from microbial oxidation of ethanol by oral microflora such as Candida species. However, it is uncertain whether acetaldehyde concentration in human breath is related to oral condition or local production of acetaldehyde by oral microflora. The aim of this pilot study was to investigate the relationship between physiological acetaldehyde concentration and oral condition in healthy volunteers. Sixty-five volunteers (51 males and 14 females, aged from 20 to 87 years old) participated in the present study. Acetaldehyde concentration in mouth air was measured using a portable monitor. Oral examination, detection of oral Candida species and assessment of alcohol sensitivity were performed. Acetaldehyde concentration [median (25%, 75%)] in mouth air was 170.7 (73.5, 306.3) ppb. Acetaldehyde concentration in participants with a tongue coating status score of 3 was significantly higher than in those with a score of 1 (p<0.017). After removing tongue coating, acetaldehyde concentration decreased significantly (p<0.05). Acetaldehyde concentration was not correlated with other clinical parameters, presence of Candida species, smoking status or alcohol sensitivity. Physiological acetaldehyde concentration in mouth air was associated with tongue coating volume.

Alcohol-use disorders (AUDs) have been associated with increased sepsis-related mortality. As patients with AUDs are often thiamine deficient, we investigated practice patterns relating to thiamine administration in patients with AUDs presenting with septic shock and explored the association between receipt of thiamine and mortality. We performed a retrospective cohort study of patients presenting with septic shock between 2008 and 2014 at a single tertiary care center. We identified patients with an AUD diagnosis, orders for microbial cultures and use of antibiotics, vasopressor dependency, and lactate levels≥4mmol/L. We excluded those who received thiamine later than 48h of sepsis onset. We included 53 patients. Thirty-four (64%) patients received thiamine. Five patients (15%) received their first thiamine dose in the emergency department. The median time to thiamine administration was 9 (quartiles: 4, 18) hours. The first thiamine dose was most often given parenterally (68%) and for 100mg (88%). In those receiving thiamine, 15/34 (44%) died, compared to 15/19 (79%) of those not receiving thiamine, p=0.02. A considerable proportion of patients with AUDs admitted for septic shock do not receive thiamine. Thiamine administration in this patient population was associated with decreased mortality.

Treating Trauma in Addiction with EMDR: A Pilot Study.

PubMed

Perez-Dandieu, Béatrice; Tapia, Géraldine

2014-01-01

Abstract Objective: This study investigated the effects of standard eye movement desensitization and reprocessing (EMDR) protocol in chronically dependent patients. We propose that reprocessing traumatic memories with EMDR would lead to measurable changes of addiction symptoms. Twelve patients with alcohol and/or drug dependency were randomly assigned to one of two treatment conditions: treatment as usual (TAU) or TAU plus eight sessions of EMDR (TAU+EMDR). Measures of PTSD symptoms, addiction symptoms, depression, anxiety, self-esteem, and alexithymia were included in this study. The TAU+EMDR group showed a significant reduction in PTSD symptoms but not in addiction symptoms. EMDR treatment was also associated with a significant decrease in depressive symptoms, while patients receiving TAU showed no improvement in this area. The TAU+EMDR group also showed significant changes in self-esteem and alexithymia post-treatment. This study suggests that PTSD symptoms can be successfully treated with standard EMDR protocol in substance abuse patients.

College freshmen face a variety of academic and social challenges as they adjust to college life that can place them at risk for a number of negative outcomes, including depression and alcohol-related problems. Orientation classes that focus on teaching incoming students how to better cope with college-oriented stress may provide an opportunity to prevent the development of these adjustment problems. This article outlines a program based on behavioral activation that can be integrated into college orientation programs to provide a more comprehensive orientation experience. Data are presented from an initial pilot study in which 71 first-semester freshman at the University of Maryland participated in a 15-week, 2 hr per week orientation class (n = 37 in the behavioral activation-enhanced orientation classes and n = 34 in the control orientation as usual classes). Students' depression and alcohol use were evaluated at the beginning, middle, and end of the course. Results indicated a Time × Group interaction such that problem drinking (but not consumption) was significantly reduced across assessments in the behavioral activation classes and largely unchanged in the standard classes. No difference was observed in depression scores; however, fairly low depression scores across the 3 time points may have limited the opportunity to observe any meaningful impact of the orientation classes on depression. The authors conclude with a discussion of the implications of their findings for preventing adjustment problems among incoming college students and future directions.

In this study, the authors evaluated if the 120-hour distance learning (DL) course SUPERA (an acronym in Portuguese meaning "System for detection of excessive use or dependence on psychoactive substances: brief Intervention, social reinsertion and follow-up") was an effective way to train health professionals and social workers to apply screening and brief intervention (SBI) for patients with substance use disorders. In the first phase, 2420 health professionals or social workers, who had completed the course, answered an online survey about their use of the SBI. In the second phase, 25 of those professionals applied the ASSIST (Alcohol, Smoking and Substance Involvement Screening Test) followed by a brief intervention (BI) to patients with substance use disorders. Three months after the SBI delivery, independent researchers followed up 79 patients who had received SBI, reapplying the ASSIST and a questionnaire to evaluate the patients'/clients' satisfaction with the intervention they received. In the first phase, it was found that most health professionals and social workers who completed the course applied the SBI in their work and felt very motivated to do it. In the second phase of the study, at a 3-month follow-up, most patients had significantly reduced their ASSIST scores in respect of alcohol and cocaine/crack in relation to their baseline levels. Those patients classified by their ASSIST score as "suggestive of dependence" presented a significant reduction in their scores regarding alcohol, tobacco, and cocaine/crack, whereas those classified as "at risk" presented a reduction in respect of alcohol problems only. Patients associated changes in their substance use with the SBI received. A reduction in substance use-related problems was associated with the SBI applied by the health professionals or social workers trained by the DL course SUPERA. Two significant limitations of this study were the small number of participants (professionals and patients in the follow-up) and the absence of a control group in the second phase of the study.

The abbreviated Alcohol Use Disorder Identification Test for Consumption (AUDIT-C) is rapidly becoming the alcohol screening tool of choice for busy practitioners in clinical settings and by researchers keen to limit assessment burden and reactivity. Cut-off scores for detecting drinking above recommended limits vary by population, setting, country and potentially format. This validation study aimed to determine AUDIT-C thresholds that indicated risky drinking among a population of people seeking help over the Internet. The data in this study were collected in the pilot phase of the Down Your Drink trial, which recruited people seeking help over the Internet and randomised them to a web-based intervention or an information-only website. Sensitivity, specificity, and positive and negative likelihood ratios were calculated for AUDIT-C scores, relative to weekly consumption that indicated drinking above limits and higher risk drinking. Receiver-operating characteristic (ROC) curves were created to assess the performance of different cut-off scores on the AUDIT-C for men and women. Past week alcohol consumption was used as the reference-standard and was collected via the TOT-AL, a validated online measure of past week drinking. AUDIT-C scores were obtained from 3720 adults (2053 female and 1667 male) searching the internet for help with drinking, mostly from the UK. The area under the ROC curve for risky drinking was 0.84 (95% CI 0.80, 0.87) (female) and 0.80 (95% CI 0.76, 0.84) (male). AUDIT-C cut-off scores for detecting risky drinking that maximise the sum of sensitivity and specificity were ≥8 for women and ≥8 for men; whereas those identifying the highest proportion of correctly classified individuals were ≥4 for women and ≥5 for men. AUDIT-C cut-off scores for detecting higher risk drinking were also calculated. AUDIT-C cut-off scores for identifying alcohol consumption above weekly limits in this largely UK based study population were substantially higher than those reported in other validation studies. Researchers and practitioners should select AUDIT-C cut-off scores according to the purpose of identifying risky drinkers and hence the relative importance of sensitivity and/or specificity.

So far no national or regional studies have been published in Germany regarding the number of fatal aviation accidents and results of autopsy findings. Therefore, we evaluated all fatal aviation accidents occurring in Lower Saxony from 1979 to 1996. A total of 96 aviation accidents occurred in this period involving 73 aeroplanes. The crashes resulted in the death of 154 people ranging in age from 19 to 68 years. The greatest number of victims in a single crash of an aircraft was (n=7). Other types of fatal accidents were crashes of aircraft and helicopter while on the ground (n=5), hot-air balloons (n=2), parachutes (n=10), hang glider accidents (n=5) and the striking of a bystander by a model airplane. Autopsies were performed on 68 of the 154 victims (44.2%), including 39 of the 73 pilots (53.4%). Some of the autopsies yielded findings relevant to the cause of the accident: gunshot wounds, the presence of alcohol or drugs in blood and preexisting diseases. Our findings emphasize the need for autopsy on all aviation accident victims, especially pilots, as this is the only reliable method to uncover all factors contributing to an accident.

To evaluate retrospectively the comorbidity of mental and addictive disorders in community mental health and substance misuse services in Madrid. The medical records of 400 patients from mental health and substance misuse services in Madrid were evaluated. Records were examined for the last 20 patients from each service unit. Dual pathology was constituted when a current diagnosis of mental and addictive disorders, excluding nicotine addiction, appeared on the patient's records. Prevalence of dual pathology was 34%. There were differences in the prevalence figures for the two kinds of service: 36.78% in substance misuse services, and 28.78% in mental health services. There was an association of dual diagnosis with alcohol or cocaine dependence, but not with opioid dependence. The mental disorders more prevalent in dually diagnosed than in non-dually diagnosed patients were mood disorders, personality disorders, and schizophrenia. There is a high prevalence of dual pathology in those seeking treatment, being higher in substance misuse services than in mental health services, and higher in patients with alcohol or cocaine dependence. These findings could be of help in the planning of care resource policies for these patients.

An acute post-rape intervention to prevent substance use and abuse.

The trauma of rape is routinely associated with extreme acute distress. Such peri-event anxiety increases risk of developing psychopathology and substance use or abuse post-rape, with the degree of initial distress positively predicting future problems. Unfortunately, the nature of post-rape forensic evidence collection procedures may exacerbate initial distress, thereby potentiating post-rape negative emotional sequelae. Consequently, substance use may increase in an effort to ameliorate this distress. To address this, a two-part video intervention was developed for use in acute post-rape time frames to (a) minimize anxiety during forensic rape examinations, thereby reducing risk of future emotional problems, and (b) prevent increased post-rape substance use and abuse. Pilot study data with 124 rape victims indicated that the low-cost, easily administered intervention was effective in reducing risk of marijuana abuse at 6 weeks. Nonstatistically significant trends also were evident for reduced marijuana use. Trends were also noted in favor of the intervention in the subgroup of women who were actively using substances pre-rape (among pre-rape alcohol users, 28% viewers vs. 43% nonviewers met criteria for post-rape alcohol abuse; among pre-rape marijuana users, the rates of post-marijuana use were 17% vs. 43%).

We tested the efficacy of daily contingent reinforcement for reducing alcohol use compared with (yoked) non-contingent reinforcement (NR) using a transdermal alcohol sensor to detect alcohol use. Pilot randomized controlled design with 1 baseline week, 3 intervention weeks and 1-month follow-up. New England, USA. Heavy drinking adults (46.7% female) not seeking treatment were randomized to (1) an escalating schedule of cash reinforcement (CR; n = 15) for days on which alcohol was neither reported nor detected or (2) yoked NR (n = 15). Reinforcement for CR participants started at $5 and increased $2 every subsequent day on which alcohol was not detected or reported, to a maximum of $17. Participants received no reinforcement for days on which alcohol use was detected or reported, and the reinforcer value was re-set to $5 the day after a drinking day. NR participants were yoked to the daily reinforcer value of an individual in the CR condition, in order of enrollment. Paired participants in CR and NR therefore received the same amount of money, but the amount for the NR participant was not behavior-related. The primary outcome was percentage of days without sensor-detected drinking. Secondary outcomes were number of consecutive days with no detected drinking, peak transdermal alcohol concentration (TAC), self-reported drinks per week and drinking below NIH low-risk guidelines. Controlling for baseline, CR had a higher percentage of days with no drinking detected (54.3%) than NR (31.2%) during intervention weeks [P = 0.05, Cohen's d = 0.74; 95% confidence interval (CI) = 0.007-1.47]. The longest period of consecutive days with no drinking detected was 8.0 for CR versus 2.9 for NR (P = 0.03, d = 0.85; 95% CI = 0.08-1.61). Peak TAC during intervention showed a non-significant group difference (P = 0.20; d = 0.48; 95% CI = 0.00-1.18); a similar result was found for drinks per week (P = 0.12; d = 0.59; 95% CI = 0.00-1.30). Four times more participants in CR drank below NIH low-risk drinking guidelines during intervention than did participants in NR: 31.1 versus 7.1% (P = 0.07; d = 0.71; 95% CI = -0.04 to 1.46). At 1-month follow-up, the highest number of consecutive days without drinking (self-report) did not differ significantly between conditions (P = 0.26), but showed a medium effect size (d = 0.44; 95% CI = -0.32 to 1.18). Cash incentives linked to a transdermal alcohol sensor can reduce heavy alcohol consumption while the incentives are in operation. © 2017 Society for the Study of Addiction.

Abstract To date, placebo-controlled drug trials targeting the core social impairment of autistic disorder (autism) have had uniformly negative results. Given this, the search for new potentially novel agents targeting the core social impairment of autism continues. Acamprosate is U.S. Food and Drug Administration–approved drug to treat alcohol dependence. The drug likely impacts both gamma-aminobutyric acid and glutamate neurotransmission. This study describes our initial open-label experience with acamprosate targeting social impairment in youth with autism. In this naturalistic report, five of six youth (mean age, 9.5 years) were judged treatment responders to acamprosate (mean dose 1,110 mg/day) over 10 to 30 weeks (mean duration, 20 weeks) of treatment. Acamprosate was well tolerated with only mild gastrointestinal adverse effects noted in three (50%) subjects. PMID:22136091

To determine the prevalence of occult brain abnormalities in magnetic resonance imaging of active amphetamine users. Prospective convenience study in a tertiary hospital emergency department (ED). Patients presenting to the ED for an amphetamine-related reason were eligible for inclusion. We collected demographic data, drug use data, and performed a mini-mental state examination (MMSE). The proportion of patients with an abnormality on their MRI scan. Of 38 patients enrolled, 30 had MRI scans. Nineteen were male and their mean age was 26.7 +/- 5.4 years (range 19-41 years). The mean age of first amphetamine use was 18 years (range 13-26 years). Sixteen patients used crystal methamphetamine (mean amount 2.5 g/week), nine used amphetamine ("speed") (mean amount 2.9 g/week), and 23 used ecstasy (mean amount 2.3 tablets/week). Marijuana was smoked by 26 (mean amount 5.9 g/week), and 28 drank alcohol (mean amount 207 g/week). The median MMSE score was 27/30 (interquartile range, 26-29). Abnormalities on brain MRI scans were identified in six patients, most commonly an unidentified bright object (n = 4). In this pilot study of brain MRI of young people attending the ED with an amphetamine-related presentation, one in five had an occult brain lesion. While the significance of this is uncertain, it is congruent with evidence that amphetamines cause brain injury.

X-1A on lakebed

The Bell Aircraft Corporation X-1A (48-1384) is photographed in 1955 sitting on the Rogers Dry Lakebed at Edwards, California. This view of the right side of the aircraft shows a middle section that contrasts quite distinctively with the over-all white paint scheme of the X-1A during its NACA High-Speed Flight Research Station tenure. The extreme cold of the liquid oxygen used as a propellant (along with alcohol) and its deleterious affect on paint dictated that the fuselage area next to the tank be left unpainted. The X-1A arrived at Edwards Air Force Base, California, on January 7, 1953. Bell test pilot Jean 'Skip' Ziegler made six test flights between 14 February and 25 April 1953. Air Force test pilots Maj. Charles 'Chuck' Yeager and Maj. Arthur 'Kit' Murray made 18 flights between 21 November 1953 and 26 August 1954. NACA test pilot Joe Walker made one successful flight on 20 July 1955. During a second flight attempt on 8 August 1955, an explosion damaged the aircraft shortly before launch. Walker climbed back up into the JTB-29A mothership, and the X-1A was jettisoned over the Edwards AFB bombing range.

To investigate the extent to which romantic relationship status influences condom use during vaginal, oral and anal sex among students from 12 universities in the Czech Republic, Hungary, Lithuania and Slovakia. A pilot study of 880 students from the ongoing Student Life Cohort in Europe (SLiCE) study. Multiple logistic regression was conducted to establish the effect of romantic relationship status on condom use during vaginal, anal and oral sex in the previous 30 days, while adjusting for participants' age, gender, use of alcohol and other drugs prior to sex, condom-carrying practices and number of sexual partners. Of the total sample, 73.7% were currently engaged in a romantic relationship and their condom use during vaginal sex (p < 0.001), oral sex (p < 0.001) and anal sex (p = 0.003) was significantly associated with their romantic relationship status. Students who were not in a romantic relationship had the lowest odds of condom use. Use of alcohol or other drugs before sex was detrimental to condom use (odds ratio 0.5; p = 0.045) during vaginal sex. Condom use during vaginal and oral sex was lower among older students. The need to target university students with more pragmatic sexual health risk reduction interventions that accommodate the role of romantic relationships on behavioural choices is justified.

Commercial conspiracy theories: a pilot study

Furnham, Adrian

2013-01-01

There are many ways to categorise conspiracy theories. In the present study, we examined individual and demographic predictors of beliefs in commercial conspiracy theories among a British sample of over 300 women and men. Results showed many people were cynical and sceptical with regard to advertising tricks, as well as the tactics of organisations like banks and alcohol, drug and tobacco companies. Beliefs sorted into four identifiable clusters, labelled sneakiness, manipulative, change-the-rules and suppression/prevention. The high alpha for the overall scale suggested general beliefs in commercial conspiracy. Regressions suggested that those people who were less religious, more left-wing, more pessimistic, less (self-defined as) wealthy, less Neurotic and less Open-to-Experience believed there was more commercial conspiracy. Overall the individual difference variables explained relatively little of the variance in these beliefs. The implications of these findings for the literature on conspiracy theories are discussed. Limitations of the study are also discussed. PMID:23818886

Procedures for the safe destruction of liquid pentaborane(9), B5H9, by solvolysis were investigated. The objective of the study was to establish the optimum conditions for a pilot plant operation that would use water, or alcohol, or water-alcohol mixtures as the solvolysis reagent Small amounts of B5H9 sprayed from a syringe will not necessarily enflame, nor will a small pool on a spot plate. Therefore, a procedure was developed to reproducibly demonstrate the flammability of B5H9 In these tests every sample of neat B5H9 ignited and burned with a very sooty flame till the sample was consumed. The spontaneous self-ignition of B5H9 was quenched by the addition of small concentrations of the ethers THF (tetrahydrofuran) or DME (1,2-dimethoxy ethane). It was found that 10% (volume) of either provided total quenching with a large margin of safety. When these stabilized solutions were exposed to air, they decomposed and evaporated leaving a residue that was identified by NMR analysis as boric acid. Most of the laboratory solvolysis experiments used the 90% B5H9, 10% THF solution. This mixture was safer to handle and its solvolysis reactivity was virtually identical to that of 100% B5H9. Reaction rates were analyzed by measurement of hydrogen evolved during the solvolysis reactions. In terms of the minimum overall complete reaction time, the data indicate that 50150 alcohol/water is the optimum solvolysis reagent. This reaction produced a mixture of boric acid, B(OH)3, and triethoxyborane, B(OEt)3 [Et = C2H5], and mixed exchange derivatives thereof.

The spontaneous self-ignition of B5H9 was quenched by the addition of small concentrations of ethers THF (tetrahydrofuran) or DME (1,2-dimethoxy ethane). It was found that ten percent (volume) of either provided total quenching with a large margin of safety. When these stabilized solutions were exposed to air, they decomposed and evaporated leaving a residue that was identified by nuclear magnetic resonance (NMR) analysis as boric acid. Most of the laboratory solvolysis experiments used the 90 percent B5H9, 10 percent THF solution. This mixture was safer to handle and its solvolysis reactivity was virtually identical to that of 100 percent B5H9. Reaction rates were analyzed by measurement of hydrogen evolved during the solvolysis reactions. In terms of the minimum overall complete reaction time, the data indicate that 50/50 alcohol/water is the optimum solvolysis reagent. This reaction produced a mixture of boric acid, B(OH)3, and triethoxyborane, B(OEt)3[Et = C2H5], and mixed exchange derivatives thereof.

Introduction A large proportion of children and adolescents participate in organised sport, making community sports clubs a promising setting to support healthy behaviours. To date, however, there have been few interventions conducted in junior sports clubs that have targeted health-promoting practices. The primary aim of this pilot study is to assess the potential effectiveness of an intervention to implement health-promoting policies and practices in junior sporting clubs targeting alcohol and tobacco practices, healthy food and beverage availability, and physical activity via participation in sport. A secondary outcome is to assess the impact of such strategies on child exposure to alcohol and tobacco use at the club, purchasing behaviours by/for children at the club canteen and child sports participation opportunities. Methods and analysis The study will employ a cluster randomised controlled trial design and be conducted in metropolitan and regional areas of two Australian states. Randomisation will occur at the level of the football league. Community football clubs with over 40 junior players (players under 18 years) within each league will be eligible to participate. The intervention will be developed based on frameworks that consider the social, cultural and environmental factors that influence health behaviours. Intervention clubs will be supported to implement 16 practices targeting alcohol management, tobacco use, nutrition practices, new player recruitment activity, equal participation for players and the development of policies to support these practices. Trained research staff will collect outcome data via telephone interviews at baseline and follow-up. Interviews will be conducted with both club representatives and parents of junior players. Ethics and dissemination The study has been approved by the University of Newcastle Human Research Ethics Committee (H-2013-0429). The results of the study will be disseminated via peer-reviewed publications and presentations at conferences. Trial registration number ACTRN12617001044314; Pre-results. PMID:29362260

Horticultural therapy (HT) is a subgroup of occupational therapy (OT). Both HT and OT have been successful as adjunctive treatment modalities in substance abuse treatment. Studies have indicated that gardening promotes neuroendocrine and affective restoration from stress. The study intended to assess the effect of HT versus nonhorticultural OT on cortisol levels, depression, symptoms of posttraumatic stress disorder (PTSD), alcohol cravings, and quality of life. The research team designed a randomized pilot study. The study was open for participation from July 2012-October 2012. It took place during multiple occurrences of a 28-d treatment programs for substance use disorder at a Veterans Affairs medical center. Participants • Participants were 49 veterans, averaging 46.4 y old (SD = 11.9); the dropout rate was 37%. Participants were randomly assigned to the HT or the OT group. They attended supervised HT and OT groups 5 h/d for 3 wk. Outcome Measures • Pre- and posttreatment, participants completed the Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form (Q-LES-Q-SF), the Alcohol Craving Questionnaire (ACQ-NOW), the Posttraumatic Stress Disorder Checklist Civilian Version (PCLC), and the Center for Epidemiologic Studies Depression Scale (CES-D). Salivary cortisol samples were taken at wk 1, 2, and 3. A repeated measures analysis of variance (ANOVA) (F2,20 = 0.878) revealed that the HT performed was associated with a 12% reduction in salivary cortisol levels from wk 1 to wk 3, but the difference was not statistically significant (P = .43). Separate 1-way analyses of covariance (ANCOVAs) revealed no statistically significant differences in the self-administered tests, although both the Q-LES-Q-SF and CES-D showed a trend toward improving quality of life and depressive symptoms in the HT group compared with the OT group. Additional analysis of the nonbiologic tests suggests that most participants in the HT and OT had some benefit from the programmed activities. The trends suggest that HT may modulate stress in veterans, as evidenced by decreased cortisol levels and depressive symptoms, and may improve quality of life more than the programs in which the OT group participated. Further investigation with larger samples, including a nontreatment control group, is needed to determine whether the observed trends are treatment effects or due to abstinence.

Excessive alcohol consumption, a major health problem worldwide, affects about 6% of the United States population. Caring for patients with alcohol withdrawal syndrome in a hospital ward presents complex physiologic and psycho-social challenges which are best met with evidence-based practices. An academic medical center in the United States has been experiencing an increase in patients with alcohol withdrawal syndrome. However, gaps in clinician knowledge and infrastructure supporting the management of these patients still existed. The aim of this project was to improve the continuity of care of patients undergoing alcohol withdrawal in a medical surgical high acuity transitional care unit by incorporating evidence-based practices, and thereby to positively impact on patient outcomes. Specific objectives were related to standardized assessments and pharmacologic management strategies. The project used the Joanna Briggs Institute's Practical Application of Clinical Evidence System and Getting Research into Practice audit tool for promoting change in health practice. A baseline clinical audit was conducted to assess compliance with best practices for managing alcohol withdrawal syndrome, which was followed by several interventions targeted at nurses and providers. A follow-up audit was conducted to assess compliance with the implemented strategies. The follow-up audit used the same evidence-based audit criteria as those used for the baseline audit. A non-probabilistic, convenience sampling approach was used. A sample size of 15 patients was used for both the baseline and follow-up audits. The baseline audit revealed a high compliance rate for four of the five audit criteria concerning risk assessment and pharmacologic strategies. There was sub-optimal compliance (53%) with the criterion regarding use of the Clinical Institute Withdrawal Assessment of Alcohol Scale (revised) (CIWA-Ar) scale to assess patients with alcohol withdrawal. After the interventions were implemented this criterion recorded an improvement to 100% compliance. None of the patients in the pilot were transferred to the intensive care unit (ICU) for reasons relating to alcohol withdrawal. The outcomes of this project demonstrated alcohol withdrawal management can be safely undertaken outside the ICU when the patients are appropriately assessed and treated for the severity of their withdrawal symptoms. This new clinical program significantly impacted on continuity of care. Challenges were resolved using an interdisciplinary team approach. The project resulted in plans for further areas of work concerning alcohol withdrawal management, including adoption of similar approaches by other acute and transitional care units.

Non-communicable diseases have emerged as a global health issue. Role of occupation in pathogenesis of non-communicable diseases has not been explored much especially in the hospitality industry. Objectives of this study include finding risk factor prevalence among hotel workers and studying relationship between occupational group and chronic disease risk factors chiefly high body mass index. A cross-sectional study was conducted among non-managerial employees from classified hotels in India. The study participants self-administered pre-designed pilot-tested questionnaires. The risk factor prevalence rates were expressed as percentages. Chi-square test was used for bi-variate analysis. Overweight was chosen as 'outcome' variable of interest and binary multi-logistic regression analysis was used to identify determinants. The prevalence rates of tobacco use, alcohol use, inadequate physical activity and inadequate intake of fruits and vegetables were 32%, 49%, 24% and 92% respectively among hotel employees. Tobacco use was significantly common among those in food preparation and service, alcohol use among those in food service and security and leisure time physical activity among front office workers. More than two-fifths (42.7%) were overweight. Among the hotel workers, those employed in food preparation and security had higher odds of 1.650 (CI: 1.025 - 2.655) and 3.245 (CI: 1.296 - 8.129) respectively of being overweight. Prevalence of chronic disease risk factors is high among hotel workers. Risk of overweight is significantly high in food preparation and security departments and workplace interventions are necessary to address these risks.

Technology-delivered interventions are useful tools for addressing unhealthy alcohol use. Smartphones in particular offer opportunities to deliver interventions at the user's convenience. A smartphone application with 5 modules (personal feedback, self-monitoring of drinking, designated driver tool, blood alcohol content [BAC] calculator, information) was developed. Its acceptability and associations between use and drinking outcomes were assessed. One hundred thirty adults with unhealthy alcohol use (>14 [men]/>7 [women] drinks/week or ≥1 episode/month with 6 or more drinks) recruited in Switzerland (n = 70) and Canada (n = 60) were offered to use the application. Follow-up occurred after 3 months. Appreciation, usefulness, and self-reported frequency of use of the modules, and drinking outcomes (drinks/week, binge drinking) were assessed. Associations between application use and drinking at 3 months were evaluated with negative binomial and logistic regression models, adjusted for baseline values and gender. Of the participants, 48% were women, mean (SD) age: 32.8 (10.0). Follow-up rate: 86.2%. There were changes from baseline (BL) to follow-up (FU) in number of drinks/week, BL: 15.0 (16.5); FU: 10.9 (10.5), P = .01, and binge drinking, BL: 95.4%; FU: 64.3%, P < .0001. All modules had median ratings between 6 and 8 (scale of 1-10). Among the participants, 77% used the application, 76% used the personal feedback module, 41% the self-monitoring of drinking, 22% the designated driver tool, 53% the BAC calculator, and 31% the information module. Participants using the application more than once reported significantly fewer drinks/week at follow-up: Incidence Rate Ratio (IRR), number of drinks per week = 0.70 (0.51; 0.96). A smartphone application for unhealthy alcohol use appears acceptable and useful (although there is room for improvement). Without prompting, its use is infrequent. Those who used the application more than once reported less weekly drinking than those who did not. Efficacy of the application should be tested in a randomized trial with strategies to increase frequency of its use.

Six specialties were represented including Mental Health (MH). Using Depression as the paradigmatic disorder, the following objectives were developed. Objective I - Leadership and Public Education: Linkage with like-minded agencies and organizations. The core message should be simple. Major Depression is a brain disorder. Depression is treatable. Timely treatment prevents disability and suicide. Objective II - Medical Education: To improve psychiatric education, it was proposed that (1) relations between US/UK and Indian mid-level institutions be established, (2) teaching methods such as tele-psychiatry and online courses be pursued, (3) use models of teaching excellence to arouse student interest, and (4) develop core curricula for other branches of medicine, and CME. Objective III - Reduce Complications of Depression (Suicide, Alcoholism): Goals include (1) decriminalizing attempted suicide, (2) improving reporting systems, and including depression, psychosis, alcoholism, and suicide in the national registry, (3) pilot studies in vulnerable groups on risk and interventions, and (4) education of colleagues on alcoholism as a link between psychiatric and medical disorders. Objective IV - Integrating MH Treatment& Primary Health Care: The focus should be on training of general practitioners in psychiatry. Available training modules including long distance learning modules to be suitably modified for India. Collaborations and specific project designs are to be developed, implemented and monitored by each specialty group and reviewed in future summits.

Process engineering and scale-up of autotrophic Clostridium strain P11 syngas fermentation

NASA Astrophysics Data System (ADS)

Kundiyana, Dimple Kumar Aiyanna

Scope and Method of Study. Biomass gasification followed by fermentation of syngas to ethanol is a potential process to produce bioenergy. The process is currently being researched under laboratory- and pilot-scale in an effort to optimize the process conditions and make the process feasible for commercial production of ethanol and other biofuels such as butanol and propanol. The broad research objectives for the research were to improve ethanol yields during syngas fermentation and to design a economical fermentation process. The research included four statistically designed experimental studies in serum bottles, bench-scale and pilot-scale fermentors to screen alternate fermentation media components, to determine the effect of process parameters such as pH, temperature and buffer on syngas fermentation, to determine the effect of key limiting nutrients of the acetyl-CoA pathway in a continuous series reactor design, and to scale-up the syngas fermentation in a 100-L pilot scale fermentor. Findings and Conclusions. The first experimental study identified cotton seed extract (CSE) as a feasible medium for Clostridium strain P11 fermentation. The study showed that CSE at 0.5 g L-1 can potentially replace all the standard Clostridium strain P11 fermentation media components while using a media buffer did not significantly improve the ethanol production when used in fermentation with CSE. Scale-up of the CSE fermentation in 2-L and 5-L stirred tank fermentors showed 25% increase in ethanol yield. The second experimental study showed that syngas fermentation at 32°C without buffer was associated with higher ethanol concentration and reduced lag time in switching to solventogenesis. Conducting fermentation at 40°C or by lowering incubation pH to 5.0 resulted in reduced cell growth and no production of ethanol or acetic acid. The third experiment studied the effect of three limiting nutrients, calcium pantothenate, vitamin B12 and CoCl2 on syngas fermentation. Results indicated that it is possible to modulate the product formation by limiting key nutrients of acetyl-CoA pathway and using a continuous fermentation in two-stage fermentor design to improve ethanol yields. The last experimental study was conducted to commission a pilot scale fermentor, and subsequently scale-up the Clostridium strain P11 fermentation from a bench-scale to a pilot scale 100-L fermentor. Results indicated a six-fold improvement in ethanol concentration (25.3 g L-1 at the end of 59 d) compared to previous Clostridium strain P11 and Clostridium carboxidivorans fermentations plus the formation of other compounds such as isopropyl alcohol, acetic acid and butanol, which are of commercial importance.

Gut-liver axis and probiotics: Their role in non-alcoholic fatty liver disease

The incidence of obesity and its related conditions, including non-alcoholic fatty liver disease (NAFLD), has dramatically increased in all age groups worldwide. Given the health consequences of these conditions, and the subsequent economic burden on healthcare systems, their prevention and treatment have become major priorities. Because standard dietary and lifestyle changes and pathogenically-oriented therapies (e.g., antioxidants, oral hypoglycemic agents, and lipid-lowering agents) often fail due to poor compliance and/or lack of efficacy, novel approaches directed toward other pathomechanisms are needed. Here we present several lines of evidence indicating that, by increasing energy extraction in some dysbiosis conditions or small intestinal bacterial overgrowth, specific gut microbiota and/or a “low bacterial richness” may play a role in obesity, metabolic syndrome, and fatty liver. Under conditions involving a damaged intestinal barrier (“leaky gut”), the gut-liver axis may enhance the natural interactions between intestinal bacteria/bacterial products and hepatic receptors (e.g., toll-like receptors), thus promoting the following cascade of events: oxidative stress, insulin-resistance, hepatic inflammation, and fibrosis. We also discuss the possible modulation of gut microbiota by probiotics, as attempted in NAFLD animal model studies and in several pilot pediatric and adult human studies. Globally, this approach appears to be a promising and innovative add-on therapeutic tool for NAFLD in the context of multi-target therapy. PMID:25400436

We report a Thermotoga hypogea (Th) alcohol dehydrogenase (ADH)-dependent spectrophotometric assay for quantifying the amount of butanol in growth media, an advance that will facilitate rapid high-throughput screening of hypo- and hyper-butanol-producing strains of solventogenic Clostridium species. While a colorimetric nitroblue tetrazolium chloride-based assay for quantitating butanol in acetone-butanol-ethanol (ABE) fermentation broth has been described previously, we determined that Saccharomyces cerevisiae (Sc) ADH used in this earlier study exhibits approximately 13-fold lower catalytic efficiency towards butanol than ethanol. Any Sc ADH-dependent assay for primary quantitation of butanol in an ethanol-butanol mixture is therefore subject to "ethanol interference". To circumvent this limitation and better facilitate identification of hyper-butanol-producing Clostridia, we searched the literature for native ADHs that preferentially utilize butanol over ethanol and identified Th ADH as a candidate. Indeed, recombinant Th ADH exhibited a 6-fold higher catalytic efficiency with butanol than ethanol, as measured using the reduction of NADP + to NADPH that accompanies alcohol oxidation. Moreover, the assay sensitivity was not affected by the presence of acetone, acetic acid or butyric acid (typical ABE fermentation products). We broadened the utility of our assay by adapting it to a high-throughput microtiter plate-based format, and piloted it successfully in an ongoing metabolic engineering initiative.

A pilot-scale sand-based fluidized bed bioreactor (FBBR) was utilized to treat both methyl tert-butyl ether (MTBE) and tert-butyl alcohol (TBA) from a contaminated aquifer. To evaluate the potential for re-use of the treated water, we tested for a panel of water quality indicator microorganisms and potential waterborne pathogens including total coliforms, Escherichia coli, Salmonella and Shigella spp., Campylobacter jejuni, Aeromonas hydrophila, Legionella pneumophila, Vibrio cholerae, Yersinia enterocolytica and Mycobacterium avium in both influent and treated waters from the bioreactor. Total bacteria decreased during FBBR treatment. E. coli, Salmonella and Shigella spp., C. jejuni, V. cholerae, Y. enterocolytica and M. avium were not detected in aquifer water or bioreactor treated water samples. For those pathogens detected, including total coliforms, L. pneumophila and A. hydrophila, numbers were usually lower in treated water than influent samples, suggesting removal during treatment. The detection of particular bacterial species reflected their presence or absence in the influent waters. Copyright © 2012 Elsevier B.V. All rights reserved.

As Australia's self-sufficiency in petroleum is rapidly declining and a liquid-fuel crisis looms large on the horizon, the government is backing research into biomass-derived fuels. An Australian Commonwealth Scientific and Industrial Research Organization group determined that such fuels could play a major role in supplementing the liquid fuels. They envisaged that two kinds of alcohol could be used. Ethanol would be produced by the fermentation of starches and sugars derived from special energy crops. A similar compound, methanol, or wood alcohol, would be made from fibrous or woody plant materials, namely: cereal straw, bagasse, logging and timber-mill wastes, and othermore » residues. Recently, trials were begun with a pilot-scale digester to convert waste foods into methane. Working properly, it is expected to generate the equivalent of about 30 litres of petrol per day. Generally, production costs of biomass-derived fuels are expected to be about 2 to 3 times those of petrol, with world crude oil prices at October 1978 levels.« less

To characterize a subgroup of arousal parasomnias associated with violent behavior in adults. A pilot study on clinical and polysomnographic data of 13 adult patients seen in a tertiary sleep center for the suspicion of arousal parasomnia associated with violence. Nine young patients (8 males 1 female) had a common pattern of abnormalities: similar 'claustrophobic' dream-like experiences and complex, vehement dream enactments; no REM sleep without atonia on polysomnography. We call this syndrome 'violent somnambulism'. The rest of the patients had alcoholic delirium, partial epilepsy, possible REM sleep behavior disorder and a single sleep walking episode provoked by a sleeping pill. Sleep related violence needs thorough diagnostic evaluation for preventing life-threatening consequences. Violent somnambulism appears to be a distinct NREM sleep-related overlap parasomnia.

Aims We tested the efficacy of daily contingent reinforcement for reducing alcohol use compared with (yoked) noncontingent reinforcement (NR) using a transdermal alcohol sensor to detect alcohol use. Design Pilot randomized controlled design with one baseline week, three intervention weeks, and one-month follow up. Setting New England, USA. Participants Heavy drinking adults (46.7% female) not seeking treatment were randomized to 1) an escalating schedule of cash reinforcement (CR; n =15) for days on which alcohol was neither reported nor detected or 2) yoked NR (n =15). Intervention and comparator Reinforcement for CR participants started at $5 and increased $2 every subsequent day on which alcohol was not detected or reported, to a maximum of $17. Participants received no reinforcement for days on which alcohol use was detected or reported, and the reinforcer value was re-set to $5 the day after a drinking day. NR participants were yoked to the daily reinforcer value of an individual in the CR condition, in order of enrollment. Paired participants in CR and NR therefore received the same amount of money, but the amount for the NR participant was not behavior-related. Measurements The primary outcome was percent days without sensor-detected drinking. Secondary outcomes were number of consecutive days with no detected drinking, peak transdermal alcohol concentration (TAC), self-reported drinks per week, and drinking below NIH low-risk guidelines. Findings Controlling for baseline, CR had higher percent days with no drinking detected (54.3%) than NR (31.2%) during intervention weeks (p = .05, Cohen’s d = 0.74; 95% CI: 007–1.47). The longest period of consecutive days with no drinking detected was 8.0 for CR vs. 2.9 for NR (p = .03, d = 0.85; 95% CI: .08–1.61). Peak TAC during intervention showed a nonsignificant group difference (p = .20; d = .48; 95% CI: .00–1.18); a similar result was found for drinks per week (p = .12; d = .59; 95% CI: .00–1.30). Four times more participants in CR drank below NIH low-risk drinking guidelines during intervention than did participants in NR: 31.1% vs. 7.1% (p = .07; d = .71; 95% CI: −0.04–1.46). At 1-month follow up, the highest number of consecutive days without drinking (self-report) did not differ significantly between conditions (p = .26), but showed a medium effect size (d = .44; 95% CI: −.32–1.18). Conclusions Cash incentives linked to a transdermal alcohol sensor can reduce heavy alcohol consumption while the incentives are in operation. PMID:28107772

A learning-type artificial pancreas has been proposed to exploit the repetitive nature in the blood glucose dynamics. We clinically evaluated the efficacy of the learning-type artificial pancreas. We conducted a pilot clinical study in 10 participants of mean age 36.1 years (standard deviation [SD] 12.7; range 16-58) with type 1 diabetes. Each trial was conducted for eight consecutive mornings. The first two mornings were open-loop to obtain the individualized parameters. Then, the following six mornings were closed-loop, during which a learning-type model predictive control algorithm was employed to calculate the insulin infusion rate. To evaluate the algorithm's robustness, each participant took exercise or consumed alcohol on the fourth or sixth closed-loop day and the order was determined randomly. The primary outcome was the percentage of time spent in the target glucose range of 3.9-8.0 mmol/L between 0900 and 1200 h. The percentage of time with glucose spent in target range was significantly improved from 51.6% on day 1 to 71.6% on day 3 (mean difference between groups 17.9%, confidence interval [95% CI] 3.6-32.1; P = 0.020). There were no hypoglycemic episodes developed on day 3 compared with two episodes on day 1. There was no difference in the percentage of time with glucose spent in target range between exercise day versus day 5 and alcohol day versus day 5. The learning-type artificial pancreas system achieved good glycemic regulation and provided increased effectiveness over time. It showed a satisfactory performance even when the blood glucose was challenged by exercise or alcohol.

A large proportion of children and adolescents participate in organised sport, making community sports clubs a promising setting to support healthy behaviours. To date, however, there have been few interventions conducted in junior sports clubs that have targeted health-promoting practices. The primary aim of this pilot study is to assess the potential effectiveness of an intervention to implement health-promoting policies and practices in junior sporting clubs targeting alcohol and tobacco practices, healthy food and beverage availability, and physical activity via participation in sport. A secondary outcome is to assess the impact of such strategies on child exposure to alcohol and tobacco use at the club, purchasing behaviours by/for children at the club canteen and child sports participation opportunities. The study will employ a cluster randomised controlled trial design and be conducted in metropolitan and regional areas of two Australian states. Randomisation will occur at the level of the football league. Community football clubs with over 40 junior players (players under 18 years) within each league will be eligible to participate. The intervention will be developed based on frameworks that consider the social, cultural and environmental factors that influence health behaviours. Intervention clubs will be supported to implement 16 practices targeting alcohol management, tobacco use, nutrition practices, new player recruitment activity, equal participation for players and the development of policies to support these practices. Trained research staff will collect outcome data via telephone interviews at baseline and follow-up. Interviews will be conducted with both club representatives and parents of junior players.

Both alcohol advertising and public health campaigns increase alcohol consumption in the short term, and this may be attributable to attentional capture by alcohol-related cues in both types of media. The present studies investigated the association between (a) visual attention to alcohol cues and responsible drinking statements in alcohol advertising and public health campaigns, and (b) next-week drinking intentions (Study 1) and drinking behavior in the lab (Study 2). In Study 1, 90 male participants viewed 1 of 3 TV alcohol adverts (conventional advert; advert that emphasized responsible drinking; or public health campaign; between-subjects manipulation) while their visual attention to alcohol cues and responsible drinking statements was recorded, before reporting their drinking intentions. Study 2 used a within-subjects design in which 62 participants (27% male) viewed alcohol and soda advertisements while their attention to alcohol/soda cues and responsible drinking statements was recorded, before completing a bogus taste test with different alcoholic and nonalcoholic drinks. In both studies, alcohol cues attracted more attention than responsible drinking statements, except when viewing a public health TV campaign. Attention to responsible drinking statements was not associated with intentions to drink alcohol over the next week (Study 1) or alcohol consumption in the lab (Study 2). However, attention to alcohol portrayal cues within alcohol advertisements was associated with ad lib alcohol consumption in Study 2, although attention to other types of alcohol cues (brand logos, glassware, and packaging) was not associated. Future studies should investigate how responsible drinking statements might be improved to attract more attention. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Epidemiological data on dementia and cognitive impairment are scarce in South America. In Argentina, no dementia/cognitive impairment population-based epidemiological studies are available. The Ceibo Study is a population-based epidemiological study of dementia and cognitive impairment in individuals over 60 to be conducted. The present paper reports the results of the pilot phase (survey of cognitive impairment) conducted in Cañuelas (province of Buenos Aires). Methods In a door-to-door survey, trained high school students evaluated 1453 individuals aged 60 years and over in one day using a demographic data and risk factors questionnaire, the Mini-Mental State Examination (MMSE) and the 15-item Geriatric Depression Scale (GDS). Results Mean age of the individuals was 70.9 (±7.5) years, 61.4% were women, mean schooling was 5.5 (±3.5) years. Mean MMSE score was 24.5 (±4.7) and mean GDS 3.1 (±2.7). Risk factors of higher prevalence in the population under study were: hypertension (40.6%), smoking (35.1%), alcohol consumption (32.8%), high cholesterol (16.1%), diabetes (12.5%), cranial trauma with loss of consciousness (12.5%), 7 points or more on the GDS (11.7%). Prevalence of cognitive impairment for the whole sample was 23%, and 16.9% in subjects aged 60-69, 23.3% in 70-79 and 42.5% in subjects aged 80 or over . A significant correlation of cognitive impairment with age, functional illiteracy, cranial trauma, high blood pressure, inactivity and depression was found. Conclusion In this pilot study, the prevalence of cognitive impairment was comparable with previous international studies. PMID:29213927

The implementation of the points-based driving license helps to change the drivers' behavior and is related to a reduction of traffic accidents and fatalities. In Spain, when a driver loses all points, the driving license is revoked, so the driver must enroll on a Driver Awareness and Re-education (DARE) course. However, at the moment offenders are not submitted to any test to confirm absence of alcohol or drugs of abuse consumption, even when 9% of Spanish drivers lose their driving license for driving under the influence (DUI). The objective of this pilot study was the comparison of the usefulness of psychological tests and hair analysis to identify those individuals with a chronic consumption of alcohol and drugs of abuse among drivers performing DARE courses. Volunteers were submitted to the AUDIT and DAST-10 tests. Also a hair sample was collected and analyzed for ethylglucuronide (EtG) (LOQ 5pg/mg) and 35 licit and illicit drugs (LOQ 5-50pg/mg) by LC-MS/MS. Sixty-one participants with a mean age of 37.2±11.6years, and mainly men (90.2%), were recruited and performed AUDIT and DAST-10 tests. All hair samples were analyzed for EtG and 17 samples for licit and illicit drugs. Mean AUDIT score was 9.6 (SD=7.5), showing a value ≥8 (indicator of hazardous and harmful alcohol use) in 52.4% of cases. Mean DAST-10 score was 2.9 (SD=3.3), but a score ≥6 was detected in 21.3% of cases (indicating drug abuse or dependence). Twenty-two samples were positive for EtG, 8 for drugs of abuse (8 cocaine, 2 opioids, 1 amphetamines, 1 cannabis), and 3 for medicines. EtG concentration (20.7-1254.1pg/mg) was higher than the Society of Hair Testing (SoHT) cut-off for chronic alcohol consumption (≥30pg/mg) in 21 cases. All positive cases for methadone and cannabis, and half of positive cases for opioids and cocaine presented higher concentrations than SoHT cut-offs for chronic consumption. Higher AUDIT score and higher EtG concentration in hair were statistically associated with declaration of alcohol consumption ≥4 times/month and with previous fine for DUI of alcohol. In addition, AUDIT scores and EtG concentration in hair had a moderate but significant Spearman correlation (r=0.331, p<0.05). The combination of psychological tests and hair analysis seems to be a promising tool to identify individuals with chronic and problematic consumption of alcohol and drugs of abuse. Moreover, their application during driving license regranting procedures could increase the effectiveness of DARE courses, reduce recidivism and improve road safety. Copyright © 2018 Elsevier B.V.

To test the effectiveness of the Healthy School and Drugs (HSD) programme on tobacco and alcohol use in Dutch secondary special education (SE) schools, and whether this depends upon subtypes of SE schools and the level of implementation. In a quasi-experimental design with baseline and post-treatment follow-up, 363 students were allocated arbitrarily or depending on teacher motivation to either intervention condition (n = 205) or usual curriculum (n = 158). Thirteen secondary SE schools spread throughout the Netherlands. Participants were recruited during the autumn of 2013 from three school subtypes: SE for adolescents with intellectual/physical disabilities (SEI; n = 13), behavioural/emotional difficulties (SEB; n = 136) and learning disabilities/developmental disorders (SEL; n = 214). Self-reported life-time smoking prevalence and life-time drinking frequency as outcomes, and school subtype (SEL/SEB) and implementation fidelity (high/low) as moderators. No significant differences were found at follow-up in life-time smoking [odds ratio (OR) = 1.52; 95% confidence interval (CI) = 0.74-3.12] and drinking frequency (d = 0.01; 95% CI = -0.16 to 0.18). Interaction analyses revealed adverse effects in SEB students for alcohol use (d = 0.43; 95% CI = 0.16-0.69). Effect on tobacco refusal self-efficacy was moderated positively by implementation fidelity (d = 0.35; 95% CI = 0.07-0.63). The Healthy School and Drugs programme adapted for secondary special education in the Netherlands lacked clear evidence for effects on all outcomes. This pilot study suggests further that, within special education, substance use interventions may need to be targeted at school subtypes, as these may have harmful effects among students with behavioural difficulties. Finally, limited evidence was found that programme effectiveness may depend upon implementation fidelity. © 2016 Society for the Study of Addiction.

Prenatal coke: what's behind the smoke? Prenatal cocaine/alcohol exposure and school-age outcomes: the SCHOO-BE experience.

Despite media reports and educators' concerns, little substantive data have been published to document or refute the emerging reports that children prenatally exposed to cocaine have serious behavioral problems in school. Recent pilot data from this institution have indeed demonstrated teacher-reported problem behaviors following prenatal cocaine exposure after controlling for the effects of prenatal alcohol use and cigarette exposure. Imperative in the study of prenatal exposure and child outcome is an acknowledgement of the influence of other control factors such as postnatal environment, secondary exposures, and parenting issues. We report preliminary evaluation from a large ongoing historical prospective study of prenatal cocaine exposure on school-age outcomes. The primary aim of this NIDA-funded study is to determine if a relationship exists between prenatal cocaine/alcohol exposures and school behavior and, if so, to determine if the relationship is characterized by a dose-response relationship. A secondary aim evaluates the relationship between prenatal cocaine/alcohol exposures and school achievement. Both relationships will be assessed in a black, urban sample of first grade students using multivariate statistical techniques for confounding as well as mediating and moderating prenatal and postnatal variables. A third aim is to evaluate the relationship between a general standardized classroom behavioral measure and a tool designed to tap the effects thought to be specific to prenatal cocaine exposure. This interdisciplinary research team can address these aims because of the existence of a unique, prospectively collected perinatal Database, funded in part by NIAAA and NICHD. The database includes repeated measures of cocaine, alcohol, and other substances for over 3,500 births since 1986. Information from this database is combined with information from the database of one of the largest public school systems in the nation. The final sample will be composed of over 600 first grade students for whom the independent variables, prenatal cocaine/alcohol exposures, were prospectively assessed and quantified at the university maternity center. After informed consent, the primary dependent variable, school behavior, is assessed, using the PROBS-14 (a teacher consensus developed instrument), the Child Behavior Check List, and the Conners' Teacher Rating Scale. The secondary dependent measure, school achievement, is measured by the Metropolitan Achievement Text and the Test of Early Reading Ability. Control variables, such as the environment and parenting, are measured by several instruments aimed at capturing the child and family ecology since birth. All analyses will be adjusted as appropriate for prospectively gathered control variables such as perinatal risk, neonatal risk, and other prenatal drug and cigarette exposures. Further adjustment will be made for postnatal social risk factors which may influence outcome. Of particular concern are characteristics of the home (adaptation of HOME), parent (depression, stress), and neighborhood (violence exposure). Finally, postnatal exposure to lead and other drugs is being considered.

X-1 research aircraft landing on lakebed

NASA Technical Reports Server (NTRS)

1947-01-01

The first of the rocket-powered research aircraft, the X-1 (originally designated the XS-1), was a bullet-shaped airplane that was built by the Bell Aircraft Company for the US Air Force and the National Advisory Committee on Aeronautics (NACA). The mission of the X-1 was to investigate the transonic speed range (speeds from just below to just above the speed of sound) and, if possible, to break the 'sound barrier'. The first of the three X-1s was glide-tested at Pinecastle Air Force Base, FL, in early 1946. The first powered flight of the X-1 was made on Dec. 9, 1946, at Edwards Air Force Base with Chalmers Goodlin, a Bell test pilot, at the controls. On Oct. 14, 1947, with USAF Captain Charles 'Chuck' Yeager as pilot, the aircraft flew faster than the speed of sound for the first time. Captain Yeager ignited the four-chambered XLR-11 rocket engines after being air-launched from under the bomb bay of a B-29 at 21,000 ft. The 6,000-lbthrust ethyl alcohol/liquid oxygen burning rockets, built by Reaction Motors, Inc., pushed him up to a speed of 700 mph in level flight. Captain Yeager was also the pilot when the X-1 reached its maximum speed of 957 mph. Another USAF pilot. Lt. Col. Frank Everest, Jr., was credited with taking the X-1 to its maximum altitude of 71,902 ft. Eighteen pilots in all flew the X-1s. The number three plane was destroyed in a fire before ever making any powered flights. A single-place monoplane, the X-1 was 31 ft long, 10 ft high, and had a wingspan of 29 ft. It weighed 4,900 lb and carried 8,200 lb of fuel. It had a flush cockpit with a side entrance and no ejection seat. This roughly 30-second video clip shows the X-1 landing on Rogers Dry Lakebed followed by the safety chase aircraft.

To examine the feasibility of a strategy training clinical trial in a small group of adults with stroke-related cognitive impairments in inpatient rehabilitation, and to explore the impact of strategy training on disability. Non-randomized two-group intervention pilot study. Two inpatient rehabilitation units within an academic health centre. Individuals with a primary diagnosis of acute stroke, who were admitted to inpatient rehabilitation and demonstrated cognitive impairments were included. Individuals with severe aphasia; dementia; major depressive disorder, bipolar, or psychotic disorder; recent drug or alcohol abuse; and anticipated length of stay less than five days were excluded. Participants received strategy training or an attention control session in addition to usual rehabilitation care. Sessions in both groups were 30-40 minutes daily, five days per week, for the duration of inpatient rehabilitation. We assessed feasibility through participants' recruitment and retention; research intervention session number and duration; participants' comprehension and engagement; intervention fidelity; and participants' satisfaction. We assessed disability at study admission, inpatient rehabilitation discharge, 3 and 6 months using the Functional Independence Measure. Participants in both groups (5 per group) received the assigned intervention (>92% planned sessions; >94% fidelity) and completed follow-up testing. Strategy training participants in this small sample demonstrated significantly less disability at six months (M (SE) = 117 (3)) than attention control participants (M(SE) = 96 (14); t 8 = 7.87, P = 0.02). It is feasible and acceptable to administer both intervention protocols as an adjunct to acute inpatient rehabilitation, and strategy training shows promise for reducing disability.

In the face of rising rates of substance use among Mexican youth and rapidly narrowing gender differences in use, substance use prevention is an increasingly urgent priority for Mexico. Prevention interventions have been implemented in Mexico but few have been rigorously evaluated for effectiveness. This article presents the long term effects of a Mexico-based pilot study to test the feasibility of a linguistically specific (Mexican Spanish) adapted version of keepin’ it REAL, a school-based substance abuse prevention model program. University affiliated researchers from Mexico and the US collaborated on the study design, program implementation, data collection, and analysis. Students and their teachers from two middle schools (secundarias) in Guadalajara participated in this field trial of Mantente REAL (translated to Spanish). The schools were randomly assigned to treatment and control conditions. The sample of 431 students reported last 30 day substance use at three times (one pretest and two posttests). Changes in substance use behaviors over time were examined using growth curve models. Long term desired intervention effects were found for alcohol and marijuana use but not for cigarettes. The intervention effects were greater for girls than for boys in slowing the typical developmental increase over time in alcohol use. Marijuana effects were based on small numbers of users and indicate a need for larger scale studies. These findings suggest that keepin’ it REAL is a promising foundation for cultural program adaptation efforts to create efficacious school-based universal prevention interventions for middle school students in Mexico.

Lesbian, gay, bisexual, and transgender (LGBT) populations are more likely to misuse alcohol and other drugs (AOD), compared to the general population. However, LGBT engagement with AOD treatment is often precluded by insensitivity and misunderstanding of LGBT issues. These treatment barriers may be a consequence of either worker attitudes, organizational factors or a combination of both. Few studies have compared service context as an impediment to AOD treatment. This pilot study sought to examine and compare staff attitudes, knowledge and awareness of LGBT issues in two state-wide AOD services within Australia. One organization was a government service, whilst the other was faith based. A cross-sectional study of a convenience sample (N = 130) of workers employed in a state-wide government AOD service (n = 65), and a state-wide non-government service (n = 65) was conducted. Participants self-completed a questionnaire comprising tools previously used to assess staff attitudes, knowledge and awareness of LGBT issues. Few significant differences in attitudes and awareness of LGBT issues between government and non-government respondents were found. Nearly all respondents were supportive of LGBT persons irrespective of organizational context, with a small number of negative views. Although most respondents demonstrated awareness of organizational policies and practices relating to LGBT clients, many were "unsure" or "neutral" of what these might be. It is confirming that the majority of staff report supportive attitudes towards LGBT clients. Findings suggest that organizations need to continue to take leadership to strengthen organizational training and capacity to deliver LGBT friendly AOD treatment practices.

Classic hallucinogens in the treatment of addictions.

Bogenschutz, Michael P; Johnson, Matthew W

2016-01-04

Addictive disorders are very common and have devastating individual and social consequences. Currently available treatment is moderately effective at best. After many years of neglect, there is renewed interest in potential clinical uses for classic hallucinogens in the treatment of addictions and other behavioral health conditions. In this paper we provide a comprehensive review of both historical and recent clinical research on the use of classic hallucinogens in the treatment of addiction, selectively review other relevant research concerning hallucinogens, and suggest directions for future research. Clinical trial data are very limited except for the use of LSD in the treatment of alcoholism, where a meta-analysis of controlled trials has demonstrated a consistent and clinically significant beneficial effect of high-dose LSD. Recent pilot studies of psilocybin-assisted treatment of nicotine and alcohol dependence had strikingly positive outcomes, but controlled trials will be necessary to evaluate the efficacy of these treatments. Although plausible biological mechanisms have been proposed, currently the strongest evidence is for the role of mystical or other meaningful experiences as mediators of therapeutic effects. Classic hallucinogens have an excellent record of safety in the context of clinical research. Given our limited understanding of the clinically relevant effects of classic hallucinogens, there is a wealth of opportunities for research that could contribute important new knowledge and potentially lead to valuable new treatments for addiction.

Research that investigates standalone effects of a mobile phone-based cognitive behavioral therapy without any human contact for reducing both psychological distress and risky drinking has been advancing; however, the number of studies is still limited. A mobile phone app called Self Record that facilitates cognitive restructuring through self-monitoring of daily thoughts and activities was developed in Japan. This study conducted a nonrandomized controlled pilot trial of the Self Record app to investigate standalone effects of the intervention on psychological distress and alcohol consumption among Japanese workers. Additionally, we examined moderating effects of negative mood regulation expectancies, which are beliefs about one's ability to control one's negative mood. A quasi-experimental design with a 1-month follow-up was conducted online in Japan from February 2016 to March 2016. A research marketing company recruited participants. The selection criteria were being a Japanese full-time worker (age 20-59 years), experiencing mild to moderate psychological distress, and having some interest in self-record apps. Assignment to group was based on participants' willingness to use the app in the study. All participants completed outcome measures of negative mood regulation expectancies, positive well-being, general distress, depression, anxiety, and typical/most weekly alcohol consumption. From the recruitment, 15.65% (1083/6921) of participants met the inclusion criteria. Of these, 51.43% (557/1083) enrolled in the study: 54.9% (306/557) in the intervention group and 45.1% (251/557) in the control group. At the 1-month follow-up, 15.3% (85/557) of participants had dropped out. Intention-to-treat analyses revealed that participants in the intervention group reported increased typical drinking (η2=.009) and heavy drinking (η2=.001). Adherence to using the app was low; 64.8% (199/306) of participants in the intervention group discontinued using the app on the first day. Additionally, 65.7% (366/557) of the total sample did not correctly answer the validity checks in the outcome measures (eg, "Please select 'mildly agree' for this item"). Therefore, per-protocol analyses were conducted after removing these participants. Results showed that continuing app users (42/127) in the intervention group reported increases in anxiety (η2=.006), typical drinking (η2=.005), and heavy drinking (η2=.007) compared to those in the control group (85/127). Negative mood regulation expectancies moderated the effects of the intervention for general distress (beta=.39). Results were contrary to our hypotheses. Self-recording methods of standalone mobile phone interventions may heighten individuals' awareness of their pathological thought and drinking behavior, but may be insufficient to decrease them unless combined with a more intense or face-to-face intervention. Limitations include high attrition in this study; measures to improve the response rate are discussed. ©Toshitaka Hamamura, Shinichiro Suganuma, Mami Ueda, Jack Mearns, Haruhiko Shimoyama.

A cross sectional descriptive study of 2048 subjects was conducted to determine the prevalence of depression and factors influencing depression among students in secondary school from urban and rural areas in the state of Selangor, Malaysia. The children's depression inventory (CDI) developed by Maria Kovacs was used in this study. Students who participated in this study come from two urban schools and three rural schools. It was found that in the yield for scores for five factors were 9.2% have negative mood, 5% have interpersonal problems, 8.3% have ineffectiveness, 9.8% have anhedonia and 10.6% have negative self esteem. Following the interpretive guidelines for the T-scores, it was found that 10.3% of the students were much above average in the depression scale. This study also found that: 1% of students were smoking, 1.6% of students were gum sniffling, 0.9% took drugs, 4.1% took alcohol and 9.9% took things from other people. Females were more depressed than males. The Chinese students were more depressed compared to Indian students. Students whose parents had no formal education or had only primary education were more depressed than students whose parents had secondary, college or university education. Depression increased with increasing number of siblings. Depression contributed to the habit of drug abuse, gum sniffing and stealing but not to smoking and alcohol abuse. Suicidal tendencies were more likely among the depressed students. It is imperative that not only caregivers but also teachers have to be equipped with the knowledge, attitude and skills to assist secondary school children cope with their emotions, handle conflicts and manage stress early so that a more productive society will develop in the future.

Traumatic events pose great challenges on mental health services in scarcity of specialist trauma clinicians and services. Simple short screening instruments for detecting adverse psychological responses are needed. Several brief screening instruments have been developed. However, some are limited, especially in relation to reflecting the posttraumatic stress disorder (PTSD) diagnosis. Recently, several studies have challenged pre-existing ideas about PTSD’s latent structure. Factor analytic research currently supports two four factor models. One particular model contains a dysphoria factor which has been associated with depression and anxiety. The symptoms in this factor have been hailed as less specific to PTSD. The scope of this article is therefore to present a short screening instrument, based on this research; Posttraumatic Stress Disorder (PTSD) – 8 items. The PTSD-8 is shown to have good psychometric properties in three independent samples of whiplash patients (n=1710), rape victims (n=305), and disaster victims (n=516). Good test-rest reliability is also shown in a pilot study of young adults from families with alcohol problems (n=56). PMID:21253461

Nosocomial infection is a common problem in neonatal intensive care. A pilot quality improvement initiative focussing on hand hygiene and aimed at reducing nosocomial infection in very low birth weight (VLBW) infants was introduced in five Neonatal Intensive Care Units. Line associated laboratory confirmed bloodstream infection (LCBSI) and ventilator associated pneumonia (VAP) were chosen as main outcome measures. In VLBW infants, the rate of line associated LCBSI per 1000 central venous catheter days fell by 24%. The rate of VAP per 1000 ventilator days in VLBW infants fell by 38%. Pre- and post-intervention questionnaires showed a statistically significant increase in use of alcohol-based gels and increased knowledge of hand hygiene.

Increasing numbers of youth entering the juvenile justice system on drug-related charges require new practice frameworks for youth advocates. Screening, assessment and intervention capabilities have not kept pace with the youth who need them. This article presents an overview of a new approach, based on the system of care movement, to integrated care service provision for this population. Utilizing the Reclaiming Futures initiative--being piloted in 10 communities in the United States--as a model for change, the article suggests that juvenile justice, in partnership with treatment and other community stakeholders, can have a positive impact on this social problem.

The Kodiak Area Native Association (KANA) provides primary health care in Kodiak, Alaska and 6 outlying villages. KANA sought to actively improve key preventive screening rates for its patients. KANA adopted an electronic health record in 2008 and deployed national clinical reminders from the Indian Health Service for 5 key preventive screenings: tobacco use, alcohol use, depression, intimate partner violence, and a comprehensive cardiovascular exam. Clinical reminders were deployed in a 5-step process: (a) establish clinical demand, (b) pilot test reminder, (c) expand reminder to all providers, (d) measure outcomes and share results, and (e) delegate clinical reminder follow-up (primarily to nurses). Data from 2007-2011 show screening rates for all 5 measures improved considerably, to levels significantly above the national average for Indian Health Service facilities. Clinical reminders have been a key part of a multistep process to improve screening for depression, tobacco cessation, intimate partner violence, alcohol use, and cardiovascular disease. If deployed correctly, reminders are valuable tools in identifying patients who are overdue for preventive health screenings.

Preventing Drug Interactions in Active Older Adults is an educational intervention to prevent prescription and over-the-counter (OTC) drug and alcohol interactions in active, community-living older adults. The objectives of the program are to increase older adults' knowledge of potential interactions of prescription medications with OTC drugs and alcohol and to increase their confidence (self-efficacy) about how to avoid such interactions. An interactive multimedia computer software program (Personal Education Program or PEP) was designed for the learning styles and psychomotor skills of older adults. Focus groups of older adults evaluated PEP components in a formative manner during development. The program content dealing with antacids, calcium supplements, and acid reducers was pilot tested with 60 older adults recruited from local senior centers. Participants used the PEP on notebook computers equipped with infrared-sensitive touchscreens. Users of PEP had greater knowledge and self-efficacy scores than controls. Participants indicated a high degree of satisfaction with the PEP and reported their intent to make specific changes in self-medication behaviors.

2014-01-01

Objectives Research has indicated that both peers and siblings influence adolescents' alcohol use (e.g. Windle, 2000). The present two studies examined if social comparison orientation (SCO) moderates the effects of perceived friend and sibling alcohol use on adolescents' alcohol use cognitions and behaviors. Design & Methods Two studies examined the role of SCO as a moderator of social influence (perceived friend alcohol use in Study 1 and both perceived friend use and sibling-reported alcohol use in Study 2) on prototype perceptions and willingness to drink alcohol (Studies 1 & 2) as well as actual alcohol consumption (Study 2) among early adolescents. Results In Study 1, cross-sectional results indicated that SCO moderated the effect of perceived friend alcohol use on favorable images of drinkers and willingness to drink. Study 2 found that SCO moderated the effects of perceived friend use and sibling use on favorable images of alcohol users, willingness to use alcohol, and change in alcohol use over three years such that adolescents who reported engaging in social comparison more often reported greater willingness, more favorable images, and increases in alcohol use when perceived friend use or sibling use was high. Conclusions These studies highlight the importance of SCO as a moderator of susceptibility to the social influences of friends and siblings and may hold important implications for adolescent alcohol use prevention programs and models of health-risk behavior.

This pilot study aimed to test the acceptability and short-term effectiveness of a telephone-delivered multiple health behaviour change intervention for relatives of colorectal cancer survivors. A community-based sample of 22 first-degree relatives of colorectal cancer survivors were recruited via a media release. Data were collected at baseline and at six weeks (post-intervention). Outcome measures included health behaviours (physical activity, television viewing, diet, alcohol, body mass index, waist circumference and smoking), health-related quality of life (Short Form-36) and perceived colorectal cancer risk. Intervention satisfaction levels were also measured. The intervention included six telephone health coaching sessions, a participant handbook and a pedometer. It focused on behavioural risk factors for colorectal cancer [physical activity, diet (red and processed meat consumption, fruit and vegetable intake), alcohol, weight management and smoking], and colorectal cancer risk. From baseline to six weeks, improvements were observed for minutes moderate-vigorous physical activity (150.7 minutes), processed meat intake (-1.2 serves/week), vegetable intake (1 serve/day), alcohol intake (-0.4 standard drinks/day), body mass index (-1.4 kg/m2), and waist circumference (-5.1 cm). Improvements were also observed for physical (3.3) and mental (4.4) health-related quality of life. Further, compared with baseline, participants were more likely to meet Australian recommendations post-intervention for: moderate-vigorous physical activity (27.3 vs 59.1%); fruit intake (68.2 vs 81.8%); vegetable intake (4.6 vs 18.2%); alcohol consumption (59.1 vs 72.7%); body mass index (31.8 vs 45.5%) and waist circumference (18.2 vs 27.3%). At six weeks participants were more likely to believe a diagnosis of CRC was related to family history, and there was a decrease in their perceived risk of developing CRC in their lifetime following participation in CanPrevent. The intervention retention rate was 100%, participants reported that it was highly acceptable and they would recommend it to others at risk of colorectal cancer. Positive behaviour change achieved through this intervention approach has the potential to impact on the progression of CRC and other cancers or chronic diseases. A large scale randomised controlled trial is required to confirm the positive results of this acceptability and short-term effectiveness study. ACTRN12612000516886.

The objective of this study is to examine the effect of fetal alcohol exposure on later substance dependence using an adoption study method. One hundred ninety-seven adoptees were interviewed for substance abuse disorders, including nicotine, alcohol, and drug dependence. Twenty-one adoptees had mothers who drank during pregnancy. Adoptees with fetal alcohol exposure were compared with those without fetal alcohol exposure for symptoms of adult nicotine, alcohol, and drug dependence. Adoptee symptom counts for alcohol, drug, and nicotine dependence were higher for those exposed to alcohol in utero. The effect of fetal alcohol exposure remained after controlling for gender, biological parent alcohol dependence diagnosis, birth weight, gestational age and other environmental variables. Fetal alcohol exposure may produce increased risk for later nicotine, alcohol, and drug dependence. Possible effects of fetal alcohol exposure on development of adult substance use patterns needs attention in genetic studies of substance abuse.

Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease globally. Advanced fibrosis (stage 3-4) is the most robust marker for future mortality, but diagnosis requires liver biopsy. Current non-invasive scoring systems aimed to identify advanced fibrosis are imperfect. Insulin-like growth factor I (IGF-I) and its binding protein IGFBP-1 are liver derived proteins, that are involved in various liver disorders. The aim of this study was to examine the possible association between advanced fibrosis and IGF-I and IGFBP-1 in NAFLD. Fasting blood samples were obtained from 52 patients diagnosed with NAFLD by liver biopsy. Total IGF-I and IGFBP-1 concentrations were determined in serum by in-house radio-immuno-assays. IGF-I levels were age-standardized (IGF-SD). A logistic regression model was used to investigate the association of IGF-SD and IGFBP-1 with advanced fibrosis (stage 3-4). Patients with advanced fibrosis (stage 3-4 vs. 0-2) had lower IGF-SD (-1.17 vs. 0.11, p = .01) and higher mean levels of IGFBP-1 (29.9 vs. 18.8 µg/l, p = .02). IGFBP-1 was associated with presence of advanced fibrosis (OR 1.04 per unit increase, 95%CI 1.0-1.07, p = .05), while IGF-1 was negatively associated with advanced fibrosis (OR 0.63 per standard deviation, 95%CI 0.44-0.92, p = .02). This pilot study suggests an association between serum IGFBP-1 and IGF-I levels with advanced fibrosis in NAFLD patients. IGFBP1 and IGF-1 could be of interest as future biomarkers. Similar studies in larger cohorts are needed.

Alcohol portrayals in movies, music videos and soap operas and alcohol use of young people: current status and future challenges.

2012-01-01

To provide an overview of studies of the effects of alcohol portrayals in movies, music videos and soap operas on alcohol consumption among young people. Moreover, we highlight important issues that need to be addressed in future research. This paper reviews the current literature on alcohol portrayals on-screen and the associated gaps and challenges in alcohol media research. Thirteen longitudinal studies, 8 cross-sectional studies and 6 experimental studies examined the effects of alcohol portrayals on-screen on alcohol consumption among young people. They showed a relation between on-screen alcohol exposure and onset and progression of alcohol consumption. A distinction can be made between long-term effects and immediate effects on alcohol consumption. Only lately, more attention has been paid to processes underlying the effects of on-screen alcohol exposure. Replication of findings and development of new research designs is essential. On-screen alcohol exposure does not affect everyone. It is important to test individual differences in susceptibility to on-screen alcohol portrayals. Further, not all media alcohol portrayal might provoke similar effects. It is therefore essential to test the effect of different types of alcohol portrayals.

A tutorial on pilot studies: the what, why and how

PubMed Central

2010-01-01

Pilot studies for phase III trials - which are comparative randomized trials designed to provide preliminary evidence on the clinical efficacy of a drug or intervention - are routinely performed in many clinical areas. Also commonly know as "feasibility" or "vanguard" studies, they are designed to assess the safety of treatment or interventions; to assess recruitment potential; to assess the feasibility of international collaboration or coordination for multicentre trials; to increase clinical experience with the study medication or intervention for the phase III trials. They are the best way to assess feasibility of a large, expensive full-scale study, and in fact are an almost essential pre-requisite. Conducting a pilot prior to the main study can enhance the likelihood of success of the main study and potentially help to avoid doomed main studies. The objective of this paper is to provide a detailed examination of the key aspects of pilot studies for phase III trials including: 1) the general reasons for conducting a pilot study; 2) the relationships between pilot studies, proof-of-concept studies, and adaptive designs; 3) the challenges of and misconceptions about pilot studies; 4) the criteria for evaluating the success of a pilot study; 5) frequently asked questions about pilot studies; 7) some ethical aspects related to pilot studies; and 8) some suggestions on how to report the results of pilot investigations using the CONSORT format.

Conception, implementation and evaluation of a risk-reducing and health-promoting brief intervention addressed to unemployed. Control-group-study with repeated measurement. 131 unemployed took part in the intervention group and 95 persons were matched according to age and sex and served as a reference group. The intervention group were recruited via flyers, press articles and several institutions, the reference group via the journal of a health insurance company. The reference group received a questionnaire twice assessing the same health-related variables as the intervention group. In the intervention group, life style-related variables - eating habits, exercising, smoking, alcohol consumption - were assessed via questionnaire. In a one-hour counselling session based on Motivational Interviewing, participants received an individual feedback on their results of the questionnaire, including a comparison against standards and a review of their personal risks and negative consequences as well as advice and recommendations, while the decision for or against a behaviour change was left to the participant. 85.2 % of the participants of the intervention reported that the counselling met their expectations, and 86.2 % would recommend the intervention to a friend. Statistically significant effects for the intervention group compared to the control group from pre- to post-measurement could be shown for alcohol consumption, eating habits, and exercise (p

The effect of alcohol advertising on immediate alcohol consumption in college students: an experimental study.

Survey studies have emphasized a positive association between exposure to alcohol advertising on television (TV) and the onset and continuation of drinking among young people. Alcohol advertising might also directly influence viewers' consumption of alcohol while watching TV. The present study therefore tested the immediate effects of alcohol advertisements on the alcohol consumption of young adults while watching a movie. Weekly drinking, problem drinking, positive and arousal expectancies of alcohol, ad recall, attitude, and skepticism toward the ads were tested as moderators. An experimental design comparing 2 advertisement conditions (alcohol ads vs. nonalcohol ads) was used. A total of 80 men, young adult friendly dyads (ages 18 to 29) participated. The study examined actual alcohol consumption while watching a 1-hour movie with 3 advertising breaks. A multivariate regression analysis was used to examine the effects of advertisement condition on alcohol consumption. Assignment to the alcohol advertisement condition did not increase alcohol consumption. In addition, no moderating effects between advertisement condition and the individual factors on alcohol consumption were found. Viewing alcohol advertising did not lead to higher alcohol consumption in young men while watching a movie. However, replications of this study using other samples (e.g., different countries and cultures), other settings (e.g., movie theater, home), and with other designs (e.g., different movies and alcohol ads, cumulative exposure, extended exposure effects) are warranted.

2014-01-01

Human laboratory studies have a long and rich history in the field of alcoholism. Human laboratory studies have allowed for advances in alcohol research in a variety of ways, including elucidating of the neurobehavioral mechanisms of risk, identifying phenotypically distinct sub-types of alcohol users, investigating of candidate genes underlying experimental phenotypes for alcoholism, and testing mechanisms of action of alcoholism pharmacotherapies on clinically-relevant translational phenotypes, such as persons exhibiting positive-like alcohol effects or alcohol craving. Importantly, the field of human laboratory studies in addiction has progressed rapidly over the past decade and has built upon earlier findings of alcohol's neuropharmacological effects to advancing translational research on alcoholism etiology and treatment. To that end, the new generation of human laboratory studies has focused on applying new methodologies, further refining alcoholism phenotypes, and translating these findings to studies of alcoholism genetics, medication development, and pharmacogenetics. The combination of experimental laboratory approaches with recent developments in neuroscience and pharmacology has been particularly fruitful in furthering our understanding of the impact of individual differences in alcoholism risk and in treatment response. This review of the literature focuses on human laboratory studies of subjective intoxication, alcohol craving, anxiety, and behavioral economics. Each section discusses opportunities for phenotype refinement under laboratory conditions, as well as its application to translational science of alcoholism. A summary and recommendations for future research are also provided. PMID:22309888

Association Between Alcohol Sports Sponsorship and Consumption: A Systematic Review.

Concerns have been raised about the impact of alcohol sports sponsorship on harmful consumption, with some countries banning this practice or considering a ban. We review evidence on the relationship between exposure to alcohol sports sponsorship and alcohol consumption. Search of electronic databases (PubMed, Cochrane Library, Google Scholar and International Alcohol Information Database) supplemented by hand searches of references and conference proceedings to locate studies providing data on the impact of exposure to alcohol sports sponsorship and outcomes relating to alcohol consumption. Seven studies met inclusion criteria, presenting data on 12,760 participants from Australia, New Zealand, the UK, Germany, Italy, Netherlands and Poland. All studies report positive associations between exposure to alcohol sports sponsorship and self-reported alcohol consumption, but the statistical significance of results varies. Two studies found indirect exposure to alcohol sports sponsorship was associated with increased levels of drinking amongst schoolchildren, and five studies found a positive association between direct alcohol sports sponsorship and hazardous drinking amongst adult sportspeople. These findings corroborate the results of previous systematic reviews that reported a positive association between exposure to alcohol marketing and alcohol consumption. The relationship between alcohol sports sponsorship and increased drinking amongst schoolchildren will concern policymakers. Further research into the effectiveness of restrictions on alcohol sports sponsorship in reducing harmful drinking is required. © The Author 2016.

To conduct a systematic review of studies exploring the relationship between exposure to Internet-based alcohol-related content and alcohol use among young people. Searches of electronic databases and reference lists of relevant articles were conducted to retrieve studies of relevance up until December 2015. Full texts of the studies that met the inclusion criteria were read, appraised for quality using the Kmet forms and guidelines, and included in this review. Fifteen relevant studies were identified. The included studies were a mix of cross-sectional, longitudinal, experimental and qualitative studies conducted in the USA, the UK, Australia and New Zealand. The age range of the participants involved in these studies was 12-25 years. Included studies employed a variety of study designs and a range of different exposure variables and outcome measures. Studies demonstrated significant associations between exposure to Internet-based alcohol-related content and intentions to drink and positive attitudes towards alcohol drinking among young people. Exposure to alcohol-related content on the Internet might predispose young people to patterns of alcohol use by promoting alcohol as a natural and vital part of life. However, the research exploring the influence of this novel form of advertising on young people's alcohol use is emergent, and comprised primarily of cross-sectional studies. To evaluate the direction of the association between exposure to online alcohol-related content and alcohol use, we call for further research based on longitudinal designs. From 15 relevant studies identified, this review reports significant associations between exposure to Internet-based alcohol-related content and intentions to drink and positive attitudes towards alcohol drinking among young people, with different influences found at different stages of alcohol use. ©The Author 2016.

Excessive alcohol consumption is the third-leading cause of preventable death in the U.S. This systematic review is one in a series exploring effectiveness of interventions to reduce alcohol-related harms. The focus of this review was on studies evaluating the effects of the privatization of alcohol retail sales on excessive alcohol consumption and related harms. Using Community Guide methods for conducting systematic reviews, a systematic search was conducted in multiple databases up to December 2010. Reference lists of acquired articles and review papers were also scanned for additional studies. A total of 17 studies assessed the impact of privatizing retail alcohol sales on the per capita alcohol consumption, a well-established proxy for excessive alcohol consumption; 9 of these studies also examined the effects of privatization on the per capita consumption of alcoholic beverages that were not privatized. One cohort study in Finland assessed the impact of privatizing the sales of medium-strength beer (MSB) on self-reported alcohol consumption. One study in Sweden assessed the impact of re-monopolizing the sale of MSB on alcohol-related harms. Across the 17 studies, there was a 44.4% median increase in the per capita sales of privatized beverages in locations that privatized retail alcohol sales (interquartile interval: 4.5% to 122.5%). During the same time period, sales of nonprivatized alcoholic beverages decreased by a median of 2.2% (interquartile interval: -6.6% to -0.1%). Privatizing the sale of MSB in Finland was associated with a mean increase in alcohol consumption of 1.7 liters of pure alcohol per person per year. Re-monopolization of the sale of MSB in Sweden was associated with a general reduction in alcohol-related harms. According to Community Guide rules of evidence, there is strong evidence that privatization of retail alcohol sales leads to increases in excessive alcohol consumption. Published by Elsevier Inc.

To test whether reducing the standard serving size of alcoholic beverages would reduce voluntary alcohol consumption in a laboratory (study 1) and a real-world drinking environment (study 2). Additionally, we modelled the potential public health benefit of reducing the standard serving size of on-trade alcoholic beverages in the United Kingdom. Studies 1 and 2 were cluster-randomized experiments. In the additional study, we used the Sheffield Alcohol Policy Model to estimate the number of deaths and hospital admissions that would be averted per year in the United Kingdom if a policy that reduces alcohol serving sizes in the on-trade was introduced. A semi-naturalistic laboratory (study 1), a bar in Liverpool, UK (study 2). Students and university staff members (study 1: n = 114, mean age = 24.8 years, 74.6% female), residents from local community (study 2: n = 164, mean age = 34.9 years, 57.3% female). In study 1, participants were assigned randomly to receive standard or reduced serving sizes (by 25%) of alcohol during a laboratory drinking session. In study 2, customers at a bar were served alcohol in either standard or reduced serving sizes (by 28.6-33.3%). Outcome measures were units of alcohol consumed within 1 hour (study 1) and up to 3 hours (study 2). Serving size condition was the primary predictor. In study 1, a 25% reduction in alcohol serving size led to a 20.7-22.3% reduction in alcohol consumption. In study 2, a 28.6-33.3% reduction in alcohol serving size led to a 32.4-39.6% reduction in alcohol consumption. Modelling results indicated that decreasing the serving size of on-trade alcoholic beverages by 25% could reduce the number of alcohol-related hospital admissions and deaths per year in the United Kingdom by 4.4-10.5% and 5.6-13.2%, respectively. Reducing the serving size of alcoholic beverages in the United Kingdom appears to lead to a reduction in alcohol consumption within a single drinking occasion. © 2018 The Authors.

Restricting marketing of alcoholic products is purported to be a cost-effective intervention to reduce alcohol consumption. The strength of evidence supporting this claim is contested. This systematic review aimed to assess immediate effects of exposure to alcohol marketing on alcoholic beverage consumption and related cognitions. Electronic searches of nine databases, supplemented with reference list searches and forward citation tracking, were used to identify randomised, experimental studies assessing immediate effects of exposure to alcohol marketing communications on objective alcohol consumption (primary outcome), explicit or implicit alcohol-related cognitions, or selection without purchasing (secondary outcomes). Study limitations were assessed using the Cochrane Risk of Bias tool. Random and fixed effects meta-analyses were conducted to estimate effect sizes. Twenty four studies met the eligibility criteria. A meta-analysis integrating seven studies (758 participants, all students) found that viewing alcohol advertisements increased immediate alcohol consumption relative to viewing non-alcohol advertisements (SMD = 0.20, 95 % CI = 0.05, 0.34). A meta-analysis integrating six studies (631 participants, all students) did not find that viewing alcohol portrayals in television programmes or films increased consumption (SMD = 0.16, 95 % CI = -0.05, 0.37). Meta-analyses of secondary outcome data found that exposure to alcohol portrayals increased explicit alcohol-related cognitions, but did not find that exposure to alcohol advertisements influenced explicit or implicit alcohol-related cognitions. Confidence in results is diminished by underpowered analyses and unclear risk of bias. Viewing alcohol advertisements (but not alcohol portrayals) may increase immediate alcohol consumption by small amounts, equivalent to between 0.39 and 2.67 alcohol units for males and between 0.25 and 1.69 units for females. The generalizability of this finding beyond students and to other marketing channels remains to be established.

Background Pilot studies can play an important role in qualitative studies. Methodological and practical issues can be shaped and refined by undertaking pilots. Personal development and researchers' competence are enhanced and lessons learned can inform the development and quality of the main study. However, pilot studies are rarely published, despite their potential to improve knowledge and understanding of the research. Aim To present the main lessons learned from undertaking a pilot in a qualitative PhD study. Discussion This paper draws together lessons learned when undertaking a pilot as part of a qualitative research project. Important methodological and practical issues identified during the pilot study are discussed including access, recruitment, data collection and the personal development of the researcher. The resulting changes to the final study are also highlighted. Conclusion Sharing experiences of and lessons learned in a pilot study enhances personal development, improves researchers' confidence and competence, and contributes to the understanding of research. Implications for practice Pilots can be used effectively in qualitative studies to refine the final design, and provide the researcher with practical experience to enhance confidence and competence.

Pilot study of Creating Change, a new past-focused model for PTSD and substance abuse.

Najavits, Lisa M; Johnson, Kay M

2014-01-01

Creating Change (CC) is a new past-focused behavioral therapy model developed for comorbid posttraumatic stress disorder (PTSD) and substance use disorder (SUD). It was designed to address current gaps in the field, including the need for a past-focused PTSD/SUD model that has flexibility, can work with complex clients, responds to the staffing and resource limitations of SUD and other community-based treatment programs, can be conducted in group or individual format, and engages clients and clinicians. It was designed to follow the style, tone, and format of Seeking Safety, a successful present-focused PTSD/SUD model. CC can be used in conjunction with SS and/or other models if desired. We conducted a pilot outcome trial of the model with seven men and women outpatients diagnosed with current PTSD and SUD, who were predominantly minority and low-income, with chronic PTSD and SUD. Assessments were conducted pre- and post-treatment. Significant improvements were found in multiple domains including some PTSD and trauma-related symptoms (eg, dissociation, anxiety, depression, and sexual problems); broader psychopathology (eg, paranoia, psychotic symptoms, obsessive symptoms, and interpersonal sensitivity); daily life functioning; cognitions related to PTSD; coping strategies; and suicidal ideation (altogether 19 variables, far exceeding the rate expected by chance). Effect sizes were consistently large, including for both alcohol and drug problems. No adverse events were reported. Despite study methodology limitations, CC is promising. Clients can benefit from past-focused therapy that addresses PTSD and SUD in integrated fashion. © American Academy of Addiction Psychiatry.

The burden of hypertension and diabetes is on the increase globally with its attendant complications. Although self-care activities are critical to the successful management of both conditions, there are only a few reports on such activities, especially in this part of the world. This pilot study was therefore undertaken to assess the self-care activities among hypertensive and diabetic patients in Benin City. Hypertensive and diabetic patients were consecutively recruited from the out- patient department of the University of Benin Teaching Hospital. The questionnaires were developed based on past assessment scales such as the Hypertension Self-Care Activity Level Effects (H-SCALE) and the Summary of Diabetes Self-Care Assessment (SDSCA) for hypertensive and diabetic participants respectively. A total of 85(32 hypertensive, 24 diabetic and 29 co-morbid hypertensive diabetic) participants completed the study. Only 14 (16.5%) subjects had good self-care practice, 39 (45.9%) had fair practice while poor self-care practice was found in 32 (37.6%) subjects. Adherence to medications, clinic adherence, use of self-monitoring devices, regular exercising and dietician contact were generally low. However, only a relatively few subjects smoked tobacco or took significant alcohol. The health-related self-care practice among the patients was generally not good. There was no significant difference in the overall level of self-care among hypertensive, diabetic patients or those with co-morbid conditions. There is need for more aggressive health education aimed at improving the current health-related self-care habits among these patients.

This study investigated the coadministration of an energy drink with alcohol to study the effects on subjective intoxication and objective performance. This study aims to evaluate the objective and subjective effects of alcohol versus placebo at two alcohol doses, alone and in combination with an energy drink, in a balanced order, placebo-controlled, double-blind design. Two groups of ten healthy volunteers, mean (SD) age of 24 (6.5), participated in the study. One group consumed energy drink containing 80 mg of caffeine and the other consumed a placebo drink, with both receiving two alcohol doses (0.046 and 0.087% breathalyser alcohol concentration). Tests included breath alcohol assessment, objective measures of performance (reaction time, word memory and Stroop task) and subjective visual analogue mood scales. Participants showed significantly impaired reaction time and memory after alcohol compared to the no alcohol condition and had poorer memory after the higher alcohol dose. Stroop performance was improved with the energy drink plus alcohol combination compared to the placebo drink plus alcohol combination. Participants felt significant subjective dose-related impairment after alcohol compared to no alcohol. Neither breath alcohol concentration nor the subjective measures showed a significant difference between the energy drink and the placebo energy drink when combined with alcohol. Subjective effects reflected awareness of alcohol intoxication and sensitivity to increasing alcohol dose. There were no overall significant group differences for subjective measures between energy drink and placebo groups in the presence of alcohol and no evidence that the energy drink masked the subjective effects of alcohol at either dose.

The purpose of this study was to interpret the dynamics of Korean alcoholic family through the lens of Confucianism, using research conducted in South Korea. To gain an in-depth understanding of the family dynamics and the lived experiences of a certain alcoholic family having a specific ethnicity, health professionals must first understand the uniqueness of their own cultural bases and how those cultural components can shape dynamics of alcoholic family. Thus, we reviewed qualitative studies of Korean families with alcoholic fathers to investigate the unique characteristics of Korean alcoholic families in terms of Confucian thoughts and values and discuss how the Confucian thoughts affect family dynamics in those Korean alcoholic families. Relevant literature was found through Korean database Research Information Sharing Service by using several (Korean) searching terms: alcoholic, home, spouse, wife, children, and family. Articles were included if they were studies of a Korean alcoholic family and used qualitative methodology. If the studies did not include familial perspectives or not focused on alcoholism issues, those studies were excluded. Eleven qualitative studies of alcoholic family were searched. The members of alcoholic families in South Korea, including the alcoholic member, have expected roles and duties because of the influence of Confucian thoughts and values. By associating with family member's alcoholism, those expectations are a big burden on those family members. Therefore, future plans for community interventions and programs for this population should incorporate the findings from this study.

Objectives To explore the collective and individual experiences that Latin American females in the U.S. have with substance abuse, violence and risky sexual behaviors. Methods This study was conducted in two phases from July 2006 to June 2007 in south Florida. This paper covers Phase 2. In Phase 2, questionnaires were provided to women to test whether there is a relationship between demographics, acculturation, depression, self-esteem and substance use/abuse; whether there is a relationship between demographics, acculturation, depression, self-esteem and violence exposure and victimization; whether there is a relationship between demographics, acculturation, depression, self-esteem, HIV knowledge and STD and HIV/AIDS risks among respondents; and whether there is a relationship between substance abuse, violence victimization and HIV/AIDS risks among respondents. Results Participants reported high rates of alcohol and drug abuse among their current or most recent partners. This is a major concern because partner alcohol use and drug use was related to partner physical, sexual and psychological abuse. Only two factors were associated with lifetime drug use: income and acculturation. Over half of the participants reported being victims of at least one form of abuse during childhood and adulthood. A substantial component of abuse reported during adulthood was perpetrated by a currently or recent intimate partner. Conclusions The results from this study suggest that substance abuse, violence and HIV should be addressed in an integrative and comprehensive manner. Recommendations for the development of policies, programs and services addressing substance abuse, violence and risk for HIV among Latinos are provided. PMID:22504304

The concerns over health and workplace hazards of formalin fixative, joined to its cross-linking of molecular groups that results in suboptimal immunohistochemistry, led us to search for an innovative safe fixative. Shellac is a natural material which is used as a preservative in foods and pharmaceutical industries. This study was undertaken to evaluate the fixation adequacy and staining quality of histopathological specimens fixed in the "shellac alcoholic solution" (SAS), and also to determine the validity of immunohistochemical staining of SAS-fixed material in comparison to those fixed in formalin. Fresh samples from 26 cases from various human tissues were collected at the frozen section room of King Abdulaziz University Hospital, and fixed in SAS fixative or in neutral buffered formaldehyde (NBF) for 12, 18, 24, and 48 h, and processed for paraffin sectioning. Deparaffinized sections were stained with hematoxylin and eosin (H&E) and immunostained for different antigens. The tissues fixed in SAS for >18 h showed best staining quality of H&E comparable to NBF-fixed tissues. Comparison of the immunohistochemical staining of different tissues yielded nearly equivalent readings with good positive nuclear staining quality in both fixatives. These findings support the fixation and preservation adequacy of SAS. Furthermore, it was concluded that the good staining quality obtained with SAS-fixed tissues, which was more or less comparable with the quality obtained with the formalin fixed tissues, supports the validity of this new solution as a good innovative fixative.

To assess the effectiveness of two personalized digital interventions (OneTooMany and Drinks Meter) compared to controls. Randomized controlled trial (AEARCTR-0,001,082). Volunteers for the study, aged 18-30, were randomly allocated to one of two interventions or one of two control groups and were followed up 4 weeks later. Primary outcomes were AUDIT-C, drinking harms and pre-loading. Drinks Meter provided participants with brief screening and advice for alcohol in addition to normative feedback, information on calories consumed and money spent. OneTooMany presented a series of socially embarrassing scenarios that may occur when drinking, and participants were scored according to if/how recently they had been experienced. The study failed to recruit and obtain sufficient follow-up data to reach a prior estimated power for detecting a difference between groups and there was no indication in the analysable sample of 402 subjects of a difference on the primary outcome measures (Drinks Meter; AUDIT-C IRR = 0.98 (0.89-1.09); Pre-loading IRR = 1.01 (0.95-1.07); Harms IRR = 0.97 (0.79-1.20); OneTooMany; AUDIT-C IRR = 0.96 (0.86-1.07); Pre-loading IRR = 0.99 (0.93-1.06); Harms IRR = 1.16 (0.94-1.43). Further research is needed on the efficacy of such instruments and their ingredients. However, recruitment and follow-up are a challenge. © The Author 2017.

Alcoholism, as it has been hypothesized, is caused by a highly heterogeneous genetic load. Since 1960, many reports have used the bio-psycho-social approach to subtype alcoholism; however, no subtypes have been genetically validated. We reviewed and compared the major single-gene, multiple-gene, and gene-to-gene interaction studies on alcoholism published during the past quarter-century, including many recent studies that have made contributions to the subtyping of alcoholism. Four subtypes of alcoholism have been reported: [1] pure alcoholism, [2] anxiety/depression alcoholism, [3] antisocial alcoholism, and [4] mixed alcoholism. Most of the important studies focused on three genes: DRD2, MAOA, and ALDH2. Therefore, our review focuses on these three genes. © 2013.

Alcohol-Induced Blackouts: A Review of Recent Clinical Research with Practical Implications and Recommendations for Future Studies.

2016-05-01

Alcohol-induced blackouts, or memory loss for all or portions of events that occurred during a drinking episode, are reported by approximately 50% of drinkers and are associated with a wide range of negative consequences, including injury and death. As such, identifying the factors that contribute to and result from alcohol-induced blackouts is critical in developing effective prevention programs. Here, we provide an updated review (2010 to 2015) of clinical research focused on alcohol-induced blackouts, outline practical and clinical implications, and provide recommendations for future research. A comprehensive, systematic literature review was conducted to examine all articles published between January 2010 through August 2015 that focused on vulnerabilities, consequences, and possible mechanisms for alcohol-induced blackouts. Twenty-six studies reported on alcohol-induced blackouts. Fifteen studies examined prevalence and/or predictors of alcohol-induced blackouts. Six publications described the consequences of alcohol-induced blackouts, and 5 studies explored potential cognitive and neurobiological mechanisms underlying alcohol-induced blackouts. Recent research on alcohol-induced blackouts suggests that individual differences, not just alcohol consumption, increase the likelihood of experiencing an alcohol-induced blackout, and the consequences of alcohol-induced blackouts extend beyond the consequences related to the drinking episode to include psychiatric symptoms and neurobiological abnormalities. Prospective studies and a standardized assessment of alcohol-induced blackouts are needed to fully characterize factors associated with alcohol-induced blackouts and to improve prevention strategies.

The objective of this cross-sectional study was to determine lumbar spine bone mineral density (BMD) in breast cancer patients previously treated with adjuvant chemotherapy. Sixteen of 27 patients who received adjuvant chemotherapy became permanently amenorrheic as a result of chemotherapy. BMD was measured at the lumbar spine using dual energy X-ray absorptiometry (DEXA). Chemotherapy drugs and dosages along with a history of risk factors for reduced bone density including activity level, tobacco and/or alcohol use, metabolic bone disease, family history, and hormone exposure were identified. Results showed that women who became permanently amenorrheic as a result of chemotherapy had BMD 14% lower than women who maintained menses after chemotherapy. Chemotherapy-treated women who maintained ovarian function had normal BMD. This study suggests that women who have premature menopause as a result of chemotherapy for breast cancer are at increased risk of bone loss and may be at risk for early development of osteoporosis. Women who maintain menses do not appear to be at risk for accelerated trabecular bone loss.

The influence of alcohol-specific communication on adolescent alcohol use and alcohol-related consequences.

Alcohol-specific communication, a direct conversation between an adult and an adolescent regarding alcohol use, contains messages about alcohol relayed from the adult to the child. The current study examined the construct of alcohol-specific communication and the effect of messages on adolescent alcohol use and alcohol-related consequences. Parent-adolescent dyads were assessed biannually for 3 years (grades 9-11 at wave 6) to examine these relations in a large longitudinal study of adolescents initially in grades 6 through 8. An exploratory factor analysis identified two factors among alcohol-specific communication items, permissive messages and negative alcohol messages. Results showed previous level of adolescent alcohol use moderated the relation between permissive messages and alcohol use outcomes. Plotting of these interactions showed greater alcohol use and consequences with increasing permissive messages in adolescents with higher versus lower levels of previous alcohol use. Results suggest that parental messages regarding alcohol use may impact adolescent alcohol use beyond the effect of general parenting style and parental alcohol use.

Alcohol use is one of the most widely accepted and studied risk factors for teen dating violence (TDV). Too little research has explored longitudinally if it is true that an adolescent's alcohol use and TDV involvement simultaneously occur. In the current study, we examined whether there were latent status based on past-year TDV and alcohol use and whether female adolescents changed their statuses of TDV and alcohol use over time. The sample consisted of 583 female youths in seven public high schools in Texas. Three waves of longitudinal data collected from 2011 to 2013 were utilised in this study. Participants completed self-report assessments of alcohol use (past-year alcohol use, number of drinks in the past month and episodic heavy drinking within the past month) and psychological and physical TDV victimisation and perpetration. Latent transition analysis was used to examine if the latent status based on TDV and alcohol use changed over time. Five separate latent statuses were identified: (i) no violence, no alcohol; (ii) alcohol; (iii) psychological violence, no alcohol; (iv) psychological violence, alcohol; and (v) physical and psychological violence, alcohol. Latent transition analysis indicated that adolescents generally remained in the same subgroup across time. This study provides evidence on the co-occurrence of alcohol use and teen dating violence, and whether teens' status based on dating violence and alcohol use are stable over time. Findings from the current study highlight the importance of targeting both TDV and substance use in intervention and prevention programs.

Ethanol is important both forensically ('drunk driving' or driving while under the influence, 'DWI', regulations) and commercially (alcoholic beverages). Blood- and breath-alcohol testing can be imposed on individuals operating private vehicles such as cars, boats, or snowmobiles, or operators of commercial vehicles like trucks, planes, and ships. The various levels of blood alcohol that determine whether these operators are considered legally impaired vary depending on the circumstances and locality. Accurate calibration and validation of instrumentation is critical in areas of forensic testing where quantitative analysis directly affects the outcome of criminal prosecutions, as is the case with the determination of ethanol in blood and breath. Additionally, the accurate assessment of the alcoholic content of beverages is a commercially important commodity. In 2002, the CCQM conducted a Key Comparison (CCQM-K27) for the determination of ethanol in aqueous matrix with nine participants. A report on this project has been approved by the CCQM and can be found at the BIPM website and in this Technical Supplement. CCQM-K27 comprised three samples, one at low mass fraction of ethanol in water (nominal concentration of 0.8 mg/g), one at high level (nominal concentration of 120 mg/g), and one wine matrix (nominal concentration of 81 mg/g). Overall agreement among eight participants using gas chromatography with flame ionization detection (GC-FID), titrimetry, isotope dilution gas chromatography/mass spectrometry (GC-IDMS), and gas chromatography-combustion-isotope ratio mass spectrometry (ID-GC-C-IRMS) was good. The ninth participant used a headspace GC-FID method that had not been validated in an earlier pilot study (CCQM-P35). A follow-on Key Comparison, CCQM-K27-Subsequent, was initiated in 2003 to accommodate laboratories that had not been ready to benchmark their methods in the original CCQM-K27 study or that wished to benchmark a different method. Four levels of ethanol in water were used in the subsequent study (nominal concentrations of 0.2 mg/g, 1 mg/g, 3 mg/g, and 60 mg/g). The three participants in the CCQM-K27-Subsequent Key Comparison demonstrated their ability to measure ethanol in aqueous matrix in the concentration range of 0.2 mg/g to 60 mg/g. Main text.

To examine the extent and content of outdoor food advertisements and food availability from outlets in the vicinity of secondary schools. The sample of schools (n=10) was randomly selected from a sample frame of schools in both an urban and rural region (Wellington and Wairarapa regions respectively) and at each extreme of the socioeconomic status (SES) distribution (based on school characteristics). An area of 1-km radius around the schools was examined for food and non-food product advertisements and shops/outlets. Out of 1408 outdoor advertisements for products, 61.5% were for food (i.e. 28 per square kilometre). The major categories were soft drinks (21.6%), frozen confectionary (16.2%), savoury snacks (11.4%), and alcohol (8.1%). Overall, 70.2% of food advertisements were for foods classified as 'unhealthy' (i.e. inconsistent with the national nutritional guidelines for adolescents). A majority of the 224 outlets sold food (i.e. 56.3%). Those that primarily sold food were (on average) closer than other outlets to the secondary schools (p=0.03). Out of those schools that sold meals, the proportion of these that advertised a salad option was significantly lower in the low SES neighbourhoods (p=0.006). Other significantly different patterns for food outlet distribution, and category of advertised food were found by SES and rurality. Although only a pilot study, the information obtained suggests that food advertising and food outlets are prevalent in the vicinity of secondary schools and that the advertising is generally not compatible with nutritional guidelines for adolescents. Larger studies into such advertising are needed as well as consideration of policy options to control aspects of the 'obesogenic environment.'

The Effects of Longitudinal Control-System Dynamics on Pilot Opinion and Response Characteristics as Determined from Flight Tests and from Ground Simulator Studies

NASA Technical Reports Server (NTRS)

Sadoff, Melvin

1958-01-01

The results of a fixed-base simulator study of the effects of variable longitudinal control-system dynamics on pilot opinion are presented and compared with flight-test data. The control-system variables considered in this investigation included stick force per g, time constant, and dead-band, or stabilizer breakout force. In general, the fairly good correlation between flight and simulator results for two pilots demonstrates the validity of fixed-base simulator studies which are designed to complement and supplement flight studies and serve as a guide in control-system preliminary design. However, in the investigation of certain problem areas (e.g., sensitive control-system configurations associated with pilot- induced oscillations in flight), fixed-base simulator results did not predict the occurrence of an instability, although the pilots noted the system was extremely sensitive and unsatisfactory. If it is desired to predict pilot-induced-oscillation tendencies, tests in moving-base simulators may be required. It was found possible to represent the human pilot by a linear pilot analog for the tracking task assumed in the present study. The criterion used to adjust the pilot analog was the root-mean-square tracking error of one of the human pilots on the fixed-base simulator. Matching the tracking error of the pilot analog to that of the human pilot gave an approximation to the variation of human-pilot behavior over a range of control-system dynamics. Results of the pilot-analog study indicated that both for optimized control-system dynamics (for poor airplane dynamics) and for a region of good airplane dynamics, the pilot response characteristics are approximately the same.

2014-05-29

Stability in alcohol habits varies over time and in subgroups, but there are few longitudinal studies assessing stability in alcohol habits by socio-demographic subgroups and potential predictors of stability and change. The aim was to study stability and change in alcohol habits by sex, age, and socio-economic position (SEP). Data derived from two longitudinal population based studies in Sweden; the PART study comprising 19 457 individuals aged 20-64 years in 1998-2000, and the Stockholm Public Health Cohort (SPHC) with 50 067 individuals aged 18-84 years in 2002. Both cohorts were followed-up twice; PART 2000-2003 and 2010, and SPHC 2007 and 2010. Alcohol habits were measured with the Alcohol Use Disorders Identification Test (AUDIT), and with normal weekly alcohol consumption (NWAC). Stability in alcohol habits was measured with intraclass correlation. Odds ratios were estimated in multinomial logistic regression analysis to predict stability in alcohol habits. For the two drinking measures there were no consistent patterns of stability in alcohol habits by sex or educational level. The stability was higher for older age groups and self-employed women. To be a man aged 30-39 at baseline predicted both increase and decrease in alcohol habits. The findings illustrate higher stability in alcohol habits with increasing age and among self-employed women with risky alcohol habits. To be a man and the age 30-39 predicted change in alcohol habits. No conclusive pattern of socio-economic position as predictor of change in alcohol habits was found and other studies of potential predictors seem warranted.

Both intoxication and chronic heavy alcohol use are associated with suicide. There is extensive population-level evidence linking per capita alcohol consumption with suicide. While alcohol policies can reduce excessive alcohol consumption, the relationship between alcohol policies and suicide warrants a critical review of the literature. This review summarizes the associations between various types of alcohol policies and suicide, both in the United States and internationally, as presented in English-language literature published between 1999 and 2014. Study designs, methodological challenges, and limitations in ascertaining the associations are discussed. Because of the substantial between-states variation in alcohol policies, U.S.-based studies contributed substantially to the literature. Repeated cross-sectional designs at both the ecological level and decedent level were common among U.S.-based studies. Non-U.S. studies often used time series data to evaluate pre-post comparisons of a hybrid set of policy changes. Although inconsistency remained, the published literature in general supported the protective effect of restrictive alcohol policies on reducing suicide as well as the decreased level of alcohol involvement among suicide decedents. Common limitations included measurement and selection bias, and a focus on effects of a limited number of alcohol policies without accounting for other alcohol policies. This review summarizes a number of studies that suggest restrictive alcohol policies may contribute to suicide prevention on a general population level, and to a reduction of alcohol involvement among suicide deaths.

A Review of Existing Studies Reporting the Negative Effects of Alcohol Access and Positive Effects of Alcohol Control Policies on Interpersonal Violence

Fitterer, Jessica L.; Nelson, Trisalyn A.; Stockwell, Timothy

2015-01-01

Alcohol consumption often leads to elevated rates of violence yet alcohol access policies continue to relax across the globe. Our review establishes the extent alcohol policy can moderate violent crime through alcohol availability restrictions. Results were informed from comprehensive selection of peer-reviewed journals from 1950 to October 2015. Our search identified 87 relevant studies on alcohol access and violence conducted across 12 countries. Seventeen studies included quasi-control design, and 23 conducted intervention analysis. Seventy-one (82%) reported a significant relationship between alcohol access and violent offenses. Alcohol outlet studies reported the greatest percentage of significant results (93%), with trading hours (63%), and alcohol price following (58%). Results from baseline studies indicated the effectiveness of increasing the price of commonly consumed alcohol, restricting the hours of alcohol trading, and limiting the number of alcohol outlets per region to prevent violent offenses. Unclear are the effects of tax reductions, restriction of on-premises re-entry, and different outlet types on violent crime. Further, the generalization of statistics over broad areas and the low number of control/intervention studies poses some concern for confounding or correlated effects on study results, and amount of information for local-level prevention of interpersonal violence. Future studies should focus on gathering longitudinal data, validating models, limiting crime data to peak drinking days and times, and wherever possible collecting the joint distribution between violent crime, intoxication, and place. A greater uptake of local-level analysis will benefit studies comparing the influence of multiple alcohol establishment types by relating the location of a crime to establishment proximity. Despite, some uncertainties particular studies showed that even modest policy changes, such as 1% increases in alcohol price, 1 h changes to closing times, and limiting establishment densities to <25 outlets per postal code substantively reduce violent crime.

Background Alcohol-induced blackouts, or memory loss for all or portions of events that occurred during a drinking episode, are reported by approximately 50% of drinkers and are associated with a wide range of negative consequences, including injury and death. As such, identifying the factors that contribute to and result from alcohol-induced blackouts is critical in developing effective prevention programs. Here, we provide an updated review (2010–2015) of clinical research focused on alcohol-induced blackouts, outline practical and clinical implications, and provide recommendations for future research. Methods A comprehensive, systematic literature review was conducted to examine all articles published between January 2010 through August 2015 that focused on examined vulnerabilities, consequences, and possible mechanisms for alcohol-induced blackouts. Results Twenty-sex studies reported on alcohol-induced blackouts. Fifteen studies examined prevalence and/or predictors of alcohol-induced blackouts. Six publications described consequences of alcohol-induced blackouts, and five studies explored potential cognitive and neurobiological mechanisms underlying alcohol-induced blackouts. Conclusions Recent research on alcohol-induced blackouts suggests that individual differences, not just alcohol consumption, increase the likelihood of experiencing an alcohol-induced blackout, and the consequences of alcohol-induced blackouts extend beyond the consequences related to the drinking episode to include psychiatric symptoms and neurobiological abnormalities. Prospective studies and a standardized assessment of alcohol-induced blackouts are needed to fully characterize factors associated with alcohol-induced blackouts and to improve prevention strategies.

Background The family is the main environment where children are socialized and learn individual behavior. Although previous studies have examined predictors of preadolescent first alcohol use, few studies have analyzed factors associated with alcohol use in children in a country with low alcohol consumption. The aim of this study was to investigate the initiation of alcohol use by sixth graders and determine family factors associated with first alcohol use. Methods Data used in this study was collected as part of the Child and Adolescent Behaviors in Long-term Evolution (CABLE) project in 2002 (when study participants were in grade 5 and aged 10–11 years) and 2003 (when study participants were in grade 6 and aged 11–12 years). Data from a total of 1,183 participants was analyzed. Main study variables included children's alcohol use: (1) never user (never user in 2002 and 2003), or (2) first-time user (never user in 2002 but ever user in 2003); parents' alcohol use: (1) both parents ever users, (2) mother ever user and father never user, (3) father ever user and mother never user, (4) both parents never users; parental support; and family conflict. Correlates of first alcohol use were identified using logistic regression. Results There were 183 students (15.5%) who became first-time users of alcohol in the sixth grade. Having parents who both used alcohol, less parental support, and more family conflict were significant predictors of sixth graders' first alcohol use. Family interaction and parents' drinking were equally important predictors of preteen's first use of alcohol. Conclusion Family factors influence children's initiation of alcohol use. It is important to educate parents about the effects of alcohol on children and to emphasize the importance of prevention. PMID:19497107

Mortality risks in alcoholism and effects of abstinence and addiction treatment.

PubMed

Miller, N S

1999-06-01

The mortality rate from alcoholism and related comorbidities is high. Studies show multiple causes of premature death from alcoholism. Several studies showed that abstinence had a positive effective on the overall survival of alcoholics. Alcoholics who abstained from alcohol, particularly continuously, showed reduced mortality rates and increased years of longevity than alcoholics who relapsed to alcohol consumption. The sources of the findings tend to be derived from treatment populations, in which abstinence is expected to occur in higher rates than in the general population.

Continuous process of preparation of n-butyl(meth)acrylate by esterification of (meth)acrylic acid by butanol on thermostable sulfo-cation exchanger

The authors propose an effective thermostable sulfo-cation exchanger based on polymers with a system of conjugated bonds, sulfopolyphenylene ketone (SPP) differing from the known cation exchangers by the high thermostability (up to 250/sup 0/C), and also having the effect of the stabilization of the double bond in unsaturated monomers. The combination of inhibiting and cation exchange properties makes it also possible to use these sulfo-cation exchangers in the processes of esterification of (meth)acrylic acids by alcohols without addition of special inhibitors. The SPP catalyst was tested in esterification processes of acrylic an methacrylic acid by butanol at a pilot plant.

Background While the utility of experimental free-access alcohol self-administration paradigms is well-established, little data exist addressing the question of whether study participation influences subsequent natural alcohol consumption. We here present drinking reports of young adults before and after participation in intravenous alcohol self-administration studies. Methods Timeline Follow-back (TLFB) drinking reports for the 6 weeks immediately preceding the first, and the 6 weeks after the last experimental alcohol challenge were examined from subjects completing one of two similar alcohol self-administration paradigms. In study 1, eighteen social drinkers (9 females, mean age 24.1 years) participated in 3 alcohol self-infusion sessions up to a maximum blood alcohol concentration (BAC) of 160 mg%. Study 2 involved 60 participants (30 females, mean age 18.3 years) of the Dresden Longitudinal Study on Alcohol Use in Young Adults (D-LAYA), who participated in 2 sessions of alcohol self-infusion up to a maximum BAC of 120 mg%, and a non-exposed age- matched control group of 42 (28 females, mean age 18.4 years) subjects. Results In study 1, participants reported (3.7%) fewer heavy drinking days as well as a decrease of 2.5 drinks per drinking day after study participation compared to pre-study levels (p<.05 respectively).. In study 2, alcohol-exposed participants reported 7.1% and non- alcohol-exposed controls 6.5% fewer drinking days at post-study measurement (p<.001), while percent heavy drinking days and drinks per drinking day did not differ. Conclusion These data suggest that participation in intravenous alcohol self-administration experiments does not increase subsequent real-life drinking of young adults. PMID:25903217

Previous research has shown diagnosis or screening for cancer may be a 'teachable moment' for prevention through lifestyle change. Previous trials have been successful but have been delivered via national programmes targeting patients being screened for colorectal cancer. This manuscript reports the protocol for a proof-of-concept study to assess the feasibility and acceptability of a lifestyle change service targeting men suspected or diagnosed with cancer of the prostate in a secondary care cancer service within the UK. Lifestyle change will be promoted through integration of a lifestyle change service in a urology department in one NHS Board. The service is delivered by a Health Psychologist and uses motivational interviewing and behavioural change techniques to motivate and support patients to consider and address topics such as increasing physical activity and a healthy diet, smoking cessation, alcohol reduction and weight loss. A service evaluation will assess feasibility and acceptability via a patient experience survey, a survey exploring staff knowledge, attitudes and practice, pre- and post-intervention lifestyle behaviour survey and an audit of routine patient database. This pilot will assess the viability of using cancer testing and diagnosis as a teachable moment for lifestyle change in a unique population (i.e. men with suspected cancer of the prostate). If successful, this approach offers potential for preventative services to enhance routine and person-centred clinical cancer care provided within secondary care settings.

To efficiently utilize water-soluble compounds in bio-oil and evaluate the potential effects of these compounds on processes such as microbial electrolysis, our study investigated the physico-chemical properties of bio-oil and the associated aqueous phase generated from switchgrass using a semi-pilot scale auger pyrolyzer. Combining separation and detection strategies with organic solvent extraction, an array of analytical instruments and methods were used to identify and quantify the chemical constituents. Separation of an aqueous phase from crude bio-oil was achieved by adding water (water: crude bio-oil at 4:1 in weight), which resulted in a partition of 61 wt.% of the organic compoundsmore » into a bio-oil aqueous phase (BOAP). GC/MS analysis for BOAP identified over 40 compounds of which 16 were quantified. Acetic acid, propionic acid, and levoglucosan are the major components in BOAP. In addition, a significant portion of chemicals that have the potential to be upgraded to hydrocarbon fuels were extracted to BOAP (77 wt.% of the alcohols, 61 wt.% of the furans, and 52 wt.% of the phenolic compounds in crude bio-oil). Valorization of the BOAP may require conversion methods capable of accommodating a very broad substrate specificity. Ultimately, a better separation strategy is needed to selectively remove the acidic and polar components from crude bio-oil to improve economic feasibility of biorefinery operations.« less

Corticosteroid modulation and testosterone changes during alcohol intoxication affects voluntary alcohol drinking.

2017-06-01

A number of studies have shown that stress and an activated hypothalamic-pituitary-adrenal (HPA) axis are associated with increased voluntary alcohol drinking. Recently, associations have been found between activated HPA and hypothalamic-pituitary-gonadal (HPG) axes in alcohol-preferring AA and non-preferring ANA, F2 (crossbred second generation from original AA and ANA), and Wistar rats. The aim of the present study has been to determine the role of corticosterone and alcohol-related testosterone-effects in subsequent alcohol drinking in AA, ANA, F2 and Wistar rats. The present study comprises of four substudies presenting new analyses of existing data, by which correlations between basal corticosterone levels, changes in testosterone levels during alcohol intoxications and subsequent voluntary alcohol consumption are investigated. The results displayed positive correlations between basal corticosterone levels and subsequent alcohol-mediated testosterone elevations, which was positively associated with voluntary alcohol consumption. The results also showed a negative correlation between basal corticosterone levels and alcohol-mediated testosterone decreases, which was negatively associated with alcohol consumption. In conclusion, the present study displays novel results, according to which the HPA axis, one hand, relates to testosterone elevation (potentially causing and/or strengthening reinforcement) during alcohol intoxication, which in turn may relate to higher voluntary alcohol consumption (AA rats). Vice versa, the HPA axis may also relate to alcohol-mediated testosterone decrease (causing testosterone reduction and disinforcement) and low-alcohol drinking (ANA, F2 and Wistar rats). In addition, the present results showed that alcohol-mediated testosterone changes may also, independently of the HPA axis, correlate with voluntary alcohol drinking, which indicate the impact of genetic factors. Thus, the role of the HPA-axis may be more related to situational stress than to intrinsic factors. In further studies, it should be investigated, whether the present results also apply to stress and human alcohol drinking. Copyright © 2017 Elsevier Inc. All rights reserved.

Changes in alcohol policies and public opinions in Finland 2003-2013.

There is a constant and ongoing interplay between public opinions and public policies, alcohol policies being no exception. This article describes the development of public opinions regarding alcohol policy in Finland during a 10-year period between 2003 and 2013. Fluctuations in the alcohol policy opinion climate are put in context by looking at concurrent changes in alcohol policies and in total alcohol consumption. The study is based on data from opinion surveys on alcohol policies commissioned by the National Institute for Health and Welfare and the Finnish Social and Health Association. The opinion polls include questions about the general acceptance of prevailing alcohol policies, appropriate sales channels of different alcoholic beverage categories and opinions about the legal age limits and prices of alcoholic beverages. In the study, changes in alcohol policy during 2003-2013 are surveyed, and their relationship with changes in alcohol policy opinion is examined. There seem to be a strong positive correlation during the study period between the level of alcohol consumption and the share of those wanting a more restrictive alcohol policy in Finland. It seems that an increased level of awareness of alcohol-related issues among the general public created a more restrictive opinion climate on alcohol policy issues after the big alcohol excise duty decrease in 2004. The reverse seems to happen but in a lesser degree when alcohol excise duties has been increased after the year 2007. © 2014 Australasian Professional Society on Alcohol and other Drugs.

This study examined the association between mean age of pilot, pilot license, pilot medical certificate and drug use trends in pilots fatally injured in aircraft accidents. The prevalence of prescription drugs, OTC drugs, controlled drugs and drugs that may be potentially impairing was also examined. This study was a descriptive observational study in which the NTSB Aviation Accident Database was searched from the period beginning January 1, 2012 to December 31, 2014. During the study period a total of 706 accidents involving 711 fatalities were investigated by the NTSB. This study included 633 of these accidents, involving 646 fatalities. Of these pilots, 42.1% had drugs in their biological samples. The prevalence of prescription drugs, controlled drugs, OTC drugs, opioids, and potentially impairing drugs in the fatally injured pilot population over the study period was 28.9%, 15.0%, 20.1%, 5.1%, and 25.5%, respectively. Pilots with any drugs in their samples were significantly older than those without drugs. Medical certificate held was associated with drug use; pilots who held third class certificates had the highest prevalence at 54.1%. Pilot license was not associated with drug use. In 3.8% of the accidents, drugs were a contributing factor in the cause. Despite current FAA medical regulations, potentially impairing drugs are frequently found in biological samples of fatally injured pilots in the U.S. More education of airmen by aviation medical examiners is needed on the safety of drug use.Akparibo IY, Stolfi A.

Depression and debt are common in the UK. Debt Counselling for Depression in Primary Care: an adaptive randomised controlled pilot trial (DeCoDer) aimed to assess the clinical effectiveness and cost-effectiveness of the addition of a primary care debt counselling advice service to usual care for patients with depression and debt. However, the study was terminated early during the internal pilot trial phase because of recruitment delays. This report describes the rationale, methods and findings of the pilot study, and implications for future research. The overarching aim of the internal pilot was to identify and resolve problems, thereby assessing the feasibility of the main trial. The specific objectives were to confirm methods for practice recruitment and the ability to recruit patients via the proposed approaches; to determine the acceptability of the study interventions and outcome measures; to assess contamination; to confirm the randomisation method for main trial and the level of participant attrition; and to check the robustness of data collection systems. An adaptive, parallel, two-group multicentre randomised controlled pilot trial with a nested mixed-methods process and economic evaluation. Both individual- and cluster (general practice)-level were was used in the pilot phase to assign participants to intervention or control groups. General practices in England and Wales. Individuals were included who were aged ≥ 18 years, scored ≥ 14 on the Beck Depression Inventory II and self-identified as having debt worries. The main exclusion criteria were being actively suicidal or psychotic and/or severely depressed and unresponsive to treatment; having a severe addiction to alcohol/illicit drugs; being unable/unwilling to give written informed consent; currently participating in other research including follow-up phases; having received Citizens Advice Bureau (CAB) debt advice in the past year; and not wanting debt advice via a general practice. The participants in the intervention group were given debt advice provided by the CAB and shared biopsychosocial assessment, in addition to treatment as usual (TAU) and two debt advice leaflets. The participants in the control group were given advice leaflets provided by the general practitioner and TAU only. (1) Outcomes of the pilot trial - the proportion of eligible patients who consented, the number of participants recruited compared with target, assessment of contamination, and assessment of patient satisfaction with intervention and outcome measures. (2) Participant outcomes - primary - Beck Depression Inventory II; secondary - psychological well-being, health and social care utilisation, service satisfaction, substance misuse, record of priority/non-priority debts, life events and difficulties, and explanatory measures. Outcomes were assessed at baseline (pre-randomisation) and at 4 months post randomisation. Other data sources - qualitative interviews were conducted with participants, clinicians and CAB advisors. Of the 238 expressions of interest screened, 61 participants (26%) were recruited and randomised (32 in the intervention group and 29 in the control group). All participants provided baseline outcomes and 52 provided the primary outcome at 4 months' follow-up (14.7% dropout). Seventeen participants allocated to the intervention saw a CAB advisor. Descriptive statistics are reported for participants with complete outcomes at baseline and 4 months' follow-up. Our qualitative findings suggest that the relationship between debt and depression is complex, and the impact of each on the other is compounded by other psychological, social and contextual influences. As a result of low recruitment, this trial was terminated at the internal pilot phase and was too small for inferential statistical analysis. We recommend ways to reduce this risk when conducting complex trials among vulnerable populations recruited in community settings. These cover trial design, the design and delivery of interventions, recruitment strategies and support for sites. Current Controlled Trials ISRCTN79705874.

Genetic research: who is at risk for alcoholism.

PubMed

Foroud, Tatiana; Edenberg, Howard J; Crabbe, John C

2010-01-01

The National Institute on Alcohol Abuse and Alcoholism (NIAAA) was founded 40 years ago to help elucidate the biological underpinnings of alcohol dependence, including the potential contribution of genetic factors. Twin, adoption, and family studies conclusively demonstrated that genetic factors account for 50 to 60 percent of the variance in risk for developing alcoholism. Case-control studies and linkage analyses have helped identify DNA variants that contribute to increased risk, and the NIAAA-sponsored Collaborative Studies on Genetics of Alcoholism (COGA) has the expressed goal of identifying contributing genes using state-of-the-art genetic technologies. These efforts have ascertained several genes that may contribute to an increased risk of alcoholism, including certain variants encoding alcohol-metabolizing enzymes and neurotransmitter receptors. Genome-wide association studies allowing the analysis of millions of genetic markers located throughout the genome will enable discovery of further candidate genes. In addition to these human studies, genetic animal models of alcohol's effects and alcohol use have greatly advanced our understanding of the genetic basis of alcoholism, resulting in the identification of quantitative trait loci and allowing for targeted manipulation of candidate genes. Novel research approaches-for example, into epigenetic mechanisms of gene regulation-also are under way and undoubtedly will further clarify the genetic basis of alcoholism.

Impulsivity Moderates Subjective Responses to Alcohol in Alcohol-Dependent Individuals.

Westman, Jonathan G; Bujarski, Spencer; Ray, Lara A

Studies of social drinkers indicate that subjective response (SR) to alcohol and impulsivity are risk factors for the development of alcohol use disorder which may be related. It is unclear, however, whether there are significant relationships between SR and impulsivity among individuals with alcohol dependence. Using data from an intravenous (IV) alcohol challenge study, the present study is the first to explore the relationship between impulsivity and SR during alcohol administration among alcohol-dependent individuals. Non-treatment-seeking, alcohol-dependent individuals (N = 42) completed the Delay Discounting Task to measure impulsivity and then completed two counterbalanced, placebo-controlled IV alcohol administration sessions, which included assessments of SR at breath alcohol concentration (BrAC) levels of 0.00, 0.02, 0.04 and 0.06 g/dl. Analyses revealed that more impulsive participants experienced higher subjective stimulation and positive mood in response to rising BrACs as compared to less impulsive individuals. More impulsive participants also experienced increased sedation over time regardless of condition (i.e. alcohol vs. saline). These findings suggest that among alcohol-dependent individuals, impulsivity is positively associated with the hedonic effects of alcohol as compared to placebo. High impulsivity may characterize a subset of alcohol-dependent individuals who drink to experience the rewarding effects of alcohol. © The Author 2016.

Several [ 18 F]-FDG positron emission tomography (PET) studies in alcoholics have consistently reported decreases in overall brain glucose metabolism at rest and following acute alcohol administration. However, changes in cerebral glucose utilization associated with the transition to addiction are not well understood and require longitudinal translational imaging studies in animal models of alcoholism. Here, we studied brain glucose uptake in alcohol drinking rats in order to provide convergent evidence to what has previously been reported in human studies. Brain glucose metabolism was measured by [ 18 F]-FDG microPET imaging in different male Wistar rat groups: short-term drinking (three months), long-term drinking (twelve months) and alcohol-naïve. Global and regional cerebral glucose uptake was measured at rest and following acute alcohol administration. We showed that alcohol significantly reduced the whole-brain glucose metabolism. This effect was most pronounced in the parietal cortex and cerebellum. Alcohol-induced decreases in brain [ 18 F]-FDG uptake was most apparent in alcohol-naïve rats, less intense in short-term drinkers and absent in long-term drinkers. The latter finding indicates the occurrence of tolerance to the intoxicating effects of alcohol in long-term drinking individuals. In contrast, some regions, like the ventral striatum and entorhinal cortex, showed enhanced metabolic activity, an effect that did not undergo tolerance during long-term alcohol consumption. Our findings are comparable to those described in human studies using the same methodology. We conclude that [ 18 F]-FDG PET studies in rat models of alcoholism provide good translation and can be used for future longitudinal studies investigating alterations in brain function during different stages of the addiction cycle.

Approach to the genetics of alcoholism: a review based on pathophysiology.

PubMed

Köhnke, Michael D

2008-01-01

Alcohol dependence is a common disorder with a heterogenous etiology. The results of family, twin and adoption studies on alcoholism are reviewed. These studies have revealed a heritability of alcoholism of over 50%. After evaluating the results, it was epidemiologically stated that alcoholism is heterogenous complex disorder with a multiple genetic background. Modern molecular genetic techniques allow examining specific genes involved in the pathophysiology of complex diseases such as alcoholism. Strategies for gene identification are introduced to the reader, including family-based and association studies. The susceptibility genes that are in the focus of this article have been chosen because they are known to encode for underlying mechanisms that are linked to the pathophysiology of alcoholism or that are important for the pharmacotherapeutic approaches in the treatment of alcohol dependence. Postulated candidate genes of the metabolism of alcohol and of the involved neurotransmitter systems are introduced. Genetic studies on alcoholism examining the metabolism of alcohol and the dopaminergic, GABAergic, glutamatergic, opioid, cholinergic and serotonergic neurotransmitter systems as well as the neuropeptide Y are presented. The results are critically discussed followed by a discussion of possible consequences.

Local, state, and national laws and policies that limit the days of the week on which alcoholic beverages may be sold may be a means of reducing excessive alcohol consumption and related harms. The methods of the Guide to Community Preventive Services were used to synthesize scientific evidence on the effectiveness for preventing excessive alcohol consumption and related harms of laws and policies maintaining or reducing the days when alcoholic beverages may be sold. Outcomes assessed in 14 studies that met qualifying criteria were excessive alcohol consumption and alcohol-related harms, including motor vehicle injuries and deaths, violence-related and other injuries, and health conditions. Qualifying studies assessed the effects of changes in days of sale in both on-premises settings (at which alcoholic beverages are consumed where purchased) and off-premises settings (at which alcoholic beverages may not be consumed where purchased). Eleven studies assessed the effects of adding days of sale, and three studies assessed the effects of imposing a ban on sales on a given weekend day. The evidence from these studies indicated that increasing days of sale leads to increases in excessive alcohol consumption and alcohol-related harms and that reducing the number of days that alcoholic beverages are sold generally decreases alcohol-related harms. Based on these findings, when the expansion of days of sale is being considered, laws and policies maintaining the number of days of the week that alcoholic beverages are sold at on- and off-premises outlets in local, state, and national jurisdictions are effective public health strategies for preventing excessive alcohol consumption and related harms.

Objective: Craving has long been cited by patients and providers as a principal construct in alcohol use disorders and an essential target for treatment. The goal of the current study was to examine the effects of alcohol availability (20% vs. 80% availability), access to alcohol (“open” vs. “locked” trials), and medication (oral naltrexone [Revia] vs. placebo) on self-reported craving and two behavioral measures of drinking (latency of attempt to access alcohol, amount of alcohol consumed when access permitted) in response to an alcohol-cue availability procedure. Method: Non-treatment-seeking, alcohol-dependent men and women (N = 58) self-referred for an alcohol administration study and were administered a modified alcohol-cue availability procedure under two medication conditions (naltrexone, placebo) using a within-subjects, repeated-measures design. Results: Analyses demonstrated that the experimental manipulations used in this study had differential effects on craving and patterns of drinking. Specifically, reduced availability of alcohol (i.e., when alcohol was available in only 20% as opposed to 80% of trials) resulted in greater amounts of alcohol consumed per open trial; the unanticipated blocking of access to alcohol (i.e., a “locked” trial during the 80% availability condition) triggered more rapid attempts to obtain alcohol on subsequent trials. Naltrexone, relative to placebo, was associated with significant reductions in cravings for alcohol. Conclusions: Taken together, these findings offer partial support for the cognitive processing model and reinforce the utility of evaluating both self-report and behavioral indicators of motivation to drink in studies designed to identify factors associated with the construct of craving.

Life stress events and alcohol misuse: distinguishing contributing stress events from consequential stress events.

PubMed

Hart, Kenneth E; Fazaa, Norman

2004-07-01

This study examined the relationship between life stress events and level of alcohol misuse using two stress indices. The first index consisted of stress events that are not likely to be caused by alcohol misuse (i.e., alcohol uncontaminated stress events). The second stress index consisted of items that were judged as being likely consequences of alcohol misuse (i.e., alcohol contaminated stress events). Results based on a questionnaire study of 378 undergraduates in 2000 showed that level of alcohol misuse was much more strongly related to alcohol contaminated life stress events than alcohol uncontaminated life events. Comparative analysis of the coefficients of determination indicated the effect size of the association to alcohol contaminated life stress events was 240% larger than the corresponding effect size for the association to alcohol uncontaminated life events. Results suggest that studies, which are tests of the tension reduction hypothesis, should employ greater methodological rigor to ensure measures of life stress events are not inadvertently assessing the consequences of alcohol misuse. The results highlight the need to distinguish between stressful life events that contribute to alcohol misuse and stressful life events that are consequential to alcohol misuse.

The reduction of health care costs associated with alcoholism treatment: a 14-year longitudinal study.

PubMed

Holder, H D; Blose, J O

1992-07-01

This study utilized two separate research designs to examine whether the initiation of alcoholism treatment is associated with a change in overall medical care cost in a population of alcoholics enrolled under a health plan sponsored by a large midwestern manufacturing corporation. In the longest longitudinal study of alcoholism treatment costs to date, a review of claims filed from 1974 to 1987 identified 3,729 alcoholics (3,068 of whom received treatment and 661 of whom did not). In one design, a time-series analysis found that following treatment initiation the total health care costs of treated alcoholics--including the cost of alcoholism treatment--declined by 23% to 55% from their highest pretreatment levels. Costs for identified but untreated alcoholics rose following identification. In a second design, analysis of variance was used to control for group differences including pretreatment health status and age. This analysis indicated that the posttreatment costs of treated alcoholics were 24% lower than comparable costs for untreated alcoholics. The study provides considerable evidence that alcoholism treatment can reduce overall medical costs in a heterogeneous alcoholic population (white collar/blue collar; fee-for-service/HMO).

X-1 launch from B-29 mothership

NASA Technical Reports Server (NTRS)

1947-01-01

The first of the rocket-powered research aircraft, the X-1 (originally designated the XS-1), was a bullet-shaped airplane that was built by the Bell Aircraft Company for the US Air Force and the National Advisory Committee on Aeronautics (NACA). The mission of the X-1 was to investigate the transonic speed range (speeds from just below to just above the speed of sound) and, if possible, to break the 'sound barrier'. The first of the three X-1s was glide-tested at Pinecastle Air Force Base, FL, in early 1946. The first powered flight of the X-1 was made on Dec. 9, 1946, at Edwards Air Force Base with Chalmers Goodlin, a Bell test pilot, at the controls. On Oct. 14, 1947, with USAF Captain Charles 'Chuck' Yeager as pilot, the aircraft flew faster than the speed of sound for the first time. Captain Yeager ignited the four-chambered XLR-11 rocket engines after being air-launched from under the bomb bay of a B-29 at 21,000 ft. The 6,000-lb thrust ethyl alcohol/liquid oxygen burning rockets, built by Reaction Motors, Inc., pushed him up to a speed of 700 mph in level flight. Captain Yeager was also the pilot when the X-1 reached its maximum speed of 957 mph. Another USAF pilot. Lt. Col. Frank Everest, Jr., was credited with taking the X-1 to its maximum altitude of 71,902 ft. Eighteen pilots in all flew the X-1s. The number three plane was destroyed in a fire before ever making any powered flights. A single-place monoplane, the X-1 was 31 ft long, 10 ft high, and had a wingspan of 29 ft. It weighed 4,900 lb and carried 8,200 lb of fuel. It had a flush cockpit with a side entrance and no ejection seat. This roughly 30-second video clip shows the X-1 launched from a B-29, ignition of the XLR-11 rocket engine, and the succeeding flight, including a roll. At one point, the video shows observers of the flight from the ground.

The effect of alcoholic beverage excise tax on alcohol-attributable injury mortalities.

This study examines the effect of state excise taxes on different types of alcoholic beverages (spirits, wine, and beer) on alcohol-attributable injury mortalities--deaths caused by motor vehicle accidents, suicides, homicides, and falls--in the United States between 1995 and 2004, using state-level panel data. There is evidence that injury deaths attributable to alcohol respond differently to changes in state excise taxes on alcohol-specific beverages. This study examines the direct relationship between injury deaths and excise taxes without testing the degree of the association between excise taxes and alcohol consumption. The study finds that beer taxes are negatively related to motor vehicle accident mortality, while wine taxes are negatively associated with suicides and falls. The positive coefficient of the spirit taxes on falls implies a substitution effect between spirits and wine, suggesting that an increase in spirit tax will cause spirit buyers to purchase more wine. This study finds no evidence of a relationship between homicides and state excise taxes on alcohol. Thus, the study concludes that injury deaths attributable to alcohol respond differently to the excise taxes on different types of alcoholic beverages.

Delta Opioid Pharmacology in Relation to Alcohol Behaviors

2016-01-01

Delta opioid receptors (DORs) are heavily involved in alcohol-mediated processes in the brain. In this chapter we provide an overview of studies investigating how alcohol directly impacts DOR pharmacology and of early studies indicating DOR modulation of alcohol behavior. We will offer a brief summary of the different animal species used in alcohol studies investigating DORs followed by a broader overview of the types of alcohol behaviors modulated by DORs. We will highlight a small set of studies investigating the relationship between alcohol and DORs in analgesia. We will then provide an anatomical overview linking DOR expression in specific brain regions to different alcohol behaviors. In this section, we will provide two models that try to explain how endogenous opioids acting at DORs may influence alcohol behaviors. Next, we will provide an overview of studies investigating certain new aspects of DOR pharmacology, including the formation of heteromers and biased signaling. Finally, we provide a short overview of the genetics of the DORs in relation to alcohol use disorders (AUDs) and a short statement on the potential of using DOR-based therapeutics for treatment of AUDs.

Pearson, Matthew R.; Hustad, John T. P.

2014-01-01

The present study examined three alcohol-perception variables (descriptive norms, injunctive norms, and college-related alcohol beliefs) as mediators of the predictive effects of four personality traits (impulsivity, sensation seeking, anxiety sensitivity, and hopelessness) on alcohol use and alcohol-related consequences in a sample of mandated college students (n = 875). Our findings replicated several findings of a previous study of incoming freshman college students (Hustad et al., in press) in that impulsivity and hopelessness had direct effects on alcohol-related problems, sensation seeking and impulsivity had indirect effects on alcohol-related outcomes via college-related alcohol beliefs, and college-related alcohol beliefs predicted both alcohol use and alcohol-related problems. We discuss the implications of our findings for global college student interventions as well as personality-targeted interventions. PMID:24589869

Perceptions of Family Alcohol Use in a Young Adult Sample.

PubMed

Serafini, Kelly A; Stewart, David G

2015-09-01

Perceptions of family alcohol use have been linked to adolescent alcohol use behaviors, yet there have been no studies that have assessed this relationship in young adults. This study examined perceptions of family alcohol use and their association with participants' self-reported alcohol use. Participants included 171 undergraduate students (mean age = 21.67, 71.9 percent female, 75.4 percent Caucasian). Participants completed measures assessing quantity and frequency of alcohol use, negative consequences of use, and sibling relationship quality. They also reported their perceptions of alcohol use for siblings and parents during a typical week. Perceptions of siblings' quantity of weekly alcohol use were significantly associated with participants' quantity of alcohol use (r = .21, p = .006) and frequency of alcohol use (r = .23, p = .002). Perceptions of parental alcohol use were not related to the participants' alcohol use patterns.

2017-11-01

HIV and childhood sexual abuse (CSA) are intersecting public health problems for women. We pilot tested an integrated sexual risk reduction intervention for women with a history of CSA that addressed both the consequences of CSA [based on the Traumagenic Dynamics (TD) framework] and the antecedents of sexual risk behavior (based on the Information-Motivation-Behavioral Skills [IMB] model). Women with a history of CSA who were attending a public STI clinic (n = 84) were randomly assigned to a five-session integrated TD/IMB (experimental) group intervention or to a time-matched IMB-guided sexual risk reduction (control) group intervention. Preliminary findings indicated that women in the integrated TD/IMB intervention reduced their average number of episodes of unprotected sex with a primary partner, their alcohol use, and their likelihood of being in a violent relationship, relative to women in the IMB-only group. Our findings suggest that sexual risk reduction interventions that address both the consequences of CSA and the antecedents of sexual risk behavior may be efficacious in reducing sexual risk behavior among women who were sexually abused.

Paracoccus denitrificans for the effluent recycling during continuous denitrification of liquid food.

Nitrate is an undesirable component of several foods. A typical case of contamination with high nitrate contents is whey concentrate, containing nitrate in concentrations up to 25 l. The microbiological removal of nitrate by Paracoccus denitrificans under formation of harmless nitrogen in combination with a cell retention reactor is described here. Focus lies on the resource-conserving design of a microbal denitrification process. Two methods are compared. The application of polyvinyl alcohol-immobilized cells, which can be applied several times in whey feed, is compared with the implementation of a two step denitrification system. First, the whey concentrate's nitrate is removed by ion exchange and subsequently the eluent regenerated by microorganisms under their retention by crossflow filtration. Nitrite and nitrate concentrations were determined by reflectometric color measurement with a commercially available Reflectoquant device. Correction factors for these media had to be determined. During the pilot development, bioreactors from 4 to 250 mg x L(-1) and crossflow units with membrane areas from 0.02 to 0.80 m(2) were examined. Based on the results of the pilot plants, a scaling for the exemplary process of denitrifying 1,000 tons per day is discussed. Copyright 2010 American Institute of Chemical Engineers

The Glass Is Half Full: Evidence for Efficacy of Alcohol-Wise at One University But Not the Other

This research extends the growing literature about online alcohol prevention programs for first-year college students. Two independent randomized control studies, conducted at separate universities, evaluated the short-term effectiveness of Alcohol-Wise, an online alcohol prevention program not previously studied. It was hypothesized the prevention program would increase alcohol knowledge and reduce alcohol consumption, including high-risk alcohol-related behaviors, among first-year college students. At both universities, the intervention significantly increased alcohol-related knowledge. At one university, the prevention program also significantly reduced alcohol consumption and high-risk drinking behaviors, such as playing drinking games, heavy drinking, and extreme ritualistic alcohol consumption. Implications for the use of online alcohol prevention programs and student affairs are discussed. PMID:25909233

Alcohol-seeking and relapse: A focus on incentive salience and contextual conditioning.

PubMed

Valyear, Milan D; Villaruel, Franz R; Chaudhri, Nadia

2017-08-01

Environmental stimuli that reliably accompany alcohol intake can become associated with the pharmacological effects of alcohol through classical (Pavlovian) conditioning. Of growing interest to addiction researchers is whether or not this process results in the attribution of incentive salience to alcohol-predictive cues, which could motivate alcohol-seeking behavior and relapse. To evaluate this question, we present a review of rodent behavioral studies that examined the capacity of alcohol-predictive cues to (i) support sign-tracking behavior, (ii) serve as conditioned reinforcers, and (iii) produce Pavlovian-to-instrumental transfer. A second, emerging area of research is focused on delineating the role of context in alcohol-seeking behavior and relapse. Here, we review studies showing that alcohol-associated contexts (i) support conditioned place preference, (ii) renew extinguished alcohol-seeking behavior, and (iii) modulate alcohol-seeking responses elicited by discrete alcohol-predictive cues. These behavioral effects may be mediated by unique psychological processes, and have important implications for cue-reactivity studies and neurobiological research. Copyright © 2017 Elsevier B.V.

two studies aimed to explore the advice Dutch midwives give and the information Dutch pregnant women and partners of pregnant women receive about alcohol consumption in pregnancy. study 1 included individual semi-structured interviews with midwives. Study 2 involved focus groups and individual semi-structured interviews with pregnant women and partners. Interview content was based on the I-Change Model. study 1 was conducted nation-wide; Study 2 was conducted in the central and southern regions of the Netherlands. 10 midwives in Study 1; 25 pregnant women and nine partners in Study 2. study 1 showed that midwives intended to advise complete abstinence, although this advice was mostly given when women indicated to consume alcohol. Midwives reported to lack good screening skills and sufficient knowledge about the mechanisms and consequences of antenatal alcohol use and did not involve partners in their alcohol advice. In Study 2, the views of pregnant women and partners were congruent to the findings reported in Study 1. In addition, pregnant women and partners considered midwives as an important source of information on alcohol in pregnancy. Partners were interested in the subject, had a liberal view on antenatal alcohol use and felt ignored by midwives and websites. Pregnant women indicated to receive conflicting alcohol advice from their health professionals. midwives' alcohol advice requires improvement with regard to screening, knowledge about mechanisms and consequences of antenatal alcohol use and the involvement of the partners in alcohol advice during pregnancy. training should be given to Dutch midwives to increase their screening skills and their alcohol related knowledge to pregnant women. Research is needed to determine how the midwife's alcohol advice to the partner should be framed in order to optimise the partner's involvement concerning alcohol abstinence in pregnancy. More attention to the topic at a national level, for example via mass media campaigns, should also be considered to change views about alcohol use during pregnancy in all stakeholders.

Subjective and neural responses to intravenous alcohol in young adults with light and heavy drinking patterns.

Gilman, Jodi M; Ramchandani, Vijay A; Crouss, Tess; Hommer, Daniel W

2012-01-01

Heavy alcohol consumption during young adulthood is a risk factor for the development of serious alcohol use disorders. Research has shown that individual differences in subjective responses to alcohol may affect individuals' vulnerability to developing alcoholism. Studies comparing the subjective and objective response to alcohol between light and heavy drinkers (HDs), however, have yielded inconsistent results, and neural responses to alcohol in these groups have not been characterized. We performed a double-blind, placebo-controlled, randomized crossover alcohol challenge study comparing functional magnetic resonance imaging and subjective response to intravenously administered 6% v/v ethanol to a target blood alcohol concentration of 0.08% or placebo between HDs and social drinkers (SDs). During the imaging, we presented emotional cues in order to measure how emotion modulated the effects of alcohol on the brain's reward circuitry. We found that, at equivalent blood alcohol concentrations, HDs reported lower subjective alcohol effects than SDs. Alcohol significantly activated the nucleus accumbens in SDs, but not in HDs. Self-reported ratings of intoxication correlated with striatal activation, suggesting that activation may reflect subjective experience of intoxication. Fearful faces significantly activated the amygdala in the SDs only, and this activation was attenuated by alcohol. This study shows that HDs not only experience reduced subjective effects of alcohol, but also demonstrate a blunted response to alcohol in the brain's reward system. Our findings indicate that reduced subjective and neural response to alcohol in HDs may be suggestive of either the development of tolerance to alcohol, or of pre-existing decreased sensitivity to alcohol's effects.

Italian Credit Mobility Students Significantly Increase Their Alcohol Intake, Risky Drinking and Related Consequences During the Study Abroad Experience.

To examine changes in alcohol intake and consequences in Italian students studying abroad. Italian exchange students planning to study abroad were invited to report on their drinking and alcohol-related negative consequences before and after their time abroad. After excluding those who abstained throughout, data on 121 students were analysed and showed that they tended to consume more alcohol and experience more alcohol-related negative consequences compared to their pre-departure levels. The added alcohol risk of study abroad for Italian students merits consideration of possible opportunities for intervention. © The Author 2016. Medical Council on Alcohol and Oxford University Press.

Currently, time of alcohol purchase is not part of the policies to regulate alcohol consumption in South Korea. This study was conducted to determine the relationship between alcohol purchasing time and alcohol use disorder. The survey for this study was conducted in geographically diverse regions of South Korea in 2012. Respondents' purchasing behaviors for both on-licensed (i.e., allows for consumption within the premises) and off-licensed (i.e., where alcohol is consumed off the premises) outlets and time of alcohol consumption were collected. Alcohol consumption patterns were examined using the Rapid Alcohol Problem Screen 4 (RAPS4). Data were also analyzed by age, gender and purchasing time. Results showed that among the off-licensed premises, supermarkets appear to be the most popular venue while for on-licensed premises; alcohol was generally consumed inside hotels/pubs regardless of age and gender of the purchaser. Purchasing of alcohol was highest during the day and early evening period (9:00 a.m. to 9:59 p.m.). Females are most likely to abuse alcohol than males during the early morning period and is that period after 12:00 midnight. Analysis suggests that the survey instrument used in the International Alcohol Control Study is being used to collect data on alcohol purchasing time consumption; therefore, the potential is there to provide accurate results to contribute appropriate policy responses to reduce alcohol related-harm.

Neighborhood characteristics contribute to urban alcohol availability: Accounting for race/ethnicity and social disorganization.

PubMed

Snowden, Aleksandra J

2016-01-01

This study examined the role that race/ethnicity and social disorganization play in alcohol availability in Milwaukee, Wisconsin, census block groups. This study estimated negative binomial regression models to examine separately the relationship between neighborhood racial/ethnic composition and social disorganization levels for (1) total, (2) on-premise, and (3) off-premise alcohol outlets. Results of this study suggest that proportion Hispanic was positively associated with total and with off-premise alcohol outlets. Second, proportion African American was negatively associated with on-premise alcohol outlets and positively associated with off-premise alcohol outlets. Proportion Asian was not associated with total, on-premise, or off-premise alcohol outlets. However, the effects of race/ethnicity on alcohol availability were either unrelated or negatively related to alcohol outlet availability once neighborhood social disorganization levels were taken into account, and social disorganization was positively and significantly associated with all alcohol outlet types. Neighborhood characteristics contribute to alcohol availability and must be considered in any efforts aimed toward prevention of alcohol-related negative health and social outcomes.

Reinforcer pathologies: Predicting alcohol related problems in college drinking men and women.

Alcohol use in college is common, and problematic consequences of alcohol may affect college men and women differently. Approaches within behavioral economics have been used to improve our understanding of alcohol use in college students. The current study assessed relations between college students' delay discounting, demand for alcohol, and alcohol problems as measured by the Young Adult Alcohol Consequences Questionnaire (YAACQ). In this study, 80 college drinkers completed a monetary choice questionnaire that assessed delay discounting of money, a novel beer choice questionnaire that evaluated delay discounting of beer, and an alcohol purchase task that measured demand for alcohol. Behavioral economic measures associated with the reinforcer pathologies model (i.e., demand and discounting) predicted alcohol consequences as measured by the YAACQ. For men, these significant predictor variables included money discounting, beer discounting, and intensity of alcohol demand, whereas for women money discounting and essential value were significant predictors. These findings highlight the utility of the reinforcer pathologies approach for the study of alcohol use and the importance of considering gender differences in examining college drinking.

Alcohol education aims to increase knowledge on the harm related to alcohol, and to change attitudes and drinking behaviour. However, little (lasting) evidence has been found for alcohol education, in changing alcohol-related attitudes and behaviour. Social marketing uses marketing techniques to achieve a social or healthy goal, and can be used in alcohol education. Social marketing consists of eight principles: customer orientation, insight, segmentation, behavioural goals, exchange, competition, methods mix, and is theory based. This review investigates the application of social marketing in alcohol prevention interventions, and whether application of social marketing influences alcohol-related attitudes or behaviour. A literature search was conducted in PubMed, PsychInfo, Cochrane and Scopus. Inclusion criteria were that original papers had to describe the effects of an alcohol prevention intervention developed according to one or more principles of social marketing. No limits were set on the age of the participants or on the kind of alcohol prevention intervention. The abstracts of the 274 retrieved studies were reviewed and the full texts of potentially relevant studies were screened. Six studies met the inclusion criteria and were included in this review. These six studies showed associations for the application of social marketing techniques on alcohol-related attitudes or behaviour; one study relates to participation in a drinking event, four to alcohol drinking behaviour, two to driving a car while under the influence of alcohol, two to recognition of campaign messages or campaign logo, and one to awareness of the campaign. However, no associations were also found. In addition, the studies had several limitations related to a control group, response rate and study methodology. Based on this review, the effect of applying the principles of social marketing in alcohol prevention in changing alcohol-related attitudes or behaviour could not be assessed. More research, with a good quality methodology, like using a randomized control trial and measuring short, medium, and long-term effects, is required on this topic. Policy implications are discussed.

Applications of virtual reality in individuals with alcohol misuse: A systematic review.

PubMed

Ghiţă, Alexandra; Gutiérrez-Maldonado, José

2018-06-01

Alcohol use and misuse have been intensively studied, due to their negative consequences in the general population. Evidence-based literature emphasizes that alcohol craving plays a crucial role in the development and maintenance of alcohol-drinking patterns. Many individuals develop Alcohol Use Disorders (AUD); significantly, after treatment many also experience relapses, in which alcohol craving has been repeatedly implicated. Cue-exposure therapy (CET) has been widely used in the treatment of alcohol misuse, but the results are inconsistent. Virtual reality (VR) can add effectiveness to cue-exposure techniques by providing multiple variables and inputs that enable personalized alcohol use assessment and treatment. The aim of this review was to examine the applications of virtual reality in individuals who misuse alcohol. We conducted an exhaustive literature search of the Web of Science, Scopus, Embase, Google Scholar, and PsycInfo databases, using as search items terms such as "alcohol" and its derivates, and virtual reality. We identified 13 studies on alcohol craving that implemented virtual reality as an assessment or treatment tool. The studies that incorporate VR present clear limitations. First, no clinical trials were conducted to explore the efficacy of the VR as a treatment tool; nor were there any studies of the generalization of craving responses in the real world, or of the long-term effects of VR treatment. Despite these limitations, the studies included showed consistent results as regards eliciting and reducing alcohol craving. We suggest that VR shows promise as a tool for the assessment and treatment of craving among individuals with alcohol misuse. Further studies implementing VR in the field of alcohol consumption are now required. Copyright © 2018 Elsevier Ltd. All rights reserved.

Genome-wide association studies (GWAS) have revealed many single nucleotide polymorphisms (SNPs) associated with complex traits. Although these studies frequently fail to identify statistically significant associations, the top association signals from GWAS may be enriched for true associations. We therefore investigated the association of alcohol dependence with 43 SNPs selected from association signals in the first two published GWAS of alcoholism. Our analysis of 808 alcohol-dependent cases and 1,248 controls provided evidence of association of alcohol dependence with SNP rs1614972 in the ADH1C gene (unadjusted p = 0.0017). Because the GWAS study that originally reported association of alcohol dependence with this SNP [1] included only men, we also performed analyses in sex-specific strata. The results suggest that this SNP has a similar effect in both sexes (men: OR (95%CI) = 0.80 (0.66, 0.95); women: OR (95%CI) = 0.83 (0.66, 1.03)). We also observed marginal evidence of association of the rs1614972 minor allele with lower alcohol consumption in the non-alcoholic controls (p = 0.081), and independently in the alcohol-dependent cases (p = 0.046). Despite a number of potential differences between the samples investigated by the prior GWAS and the current study, data presented here provide additional support for the association of SNP rs1614972 in ADH1C with alcohol dependence and extend this finding by demonstrating association with consumption levels in both non-alcoholic and alcohol-dependent populations. Further studies should investigate the association of other polymorphisms in this gene with alcohol dependence and related alcohol-use phenotypes. PMID:23516558

1978-01-01

A pilot model analysis was performed that relates pilot control compensation, pilot aircraft system response, and aircraft response characteristics for longitudinal control. The results show that a higher aircraft short period frequency is required to achieve superior pilot aircraft system response in an altitude control task than is required in an attitude control task. These results were confirmed by a simulation study of target tracking. It was concluded that the pilot model analysis provides a theoretical basis for determining the effect of control task on pilot opinions.

Effects of three different preservation methods on the mechanical properties of human and bovine cortical bone.

In the development of new strategies for fracture fixation, new methods have to be tested biomechanically under in vitro conditions before clinical trials can be performed. The gold standard for laboratory evaluations is fresh-frozen specimen. As the availability of fresh-frozen specimens is limited and since their use bears infectious risks, specimens treated with various chemical embalming fluids are also used. These preservation methods may alter the mechanical properties of the specimens used. Therefore, the aims of the present study were to determine the effects of three different preservation methods (formalin fixation (FO), Thiel-fixation (TH), and alcohol-glycerine fixation (AG)) on the elastic and postyield mechanical properties of cortical bone and to compare these properties to those of fresh-frozen (FF) specimens. Cylindrical cortical specimens (diameter 3mm, length 60 mm) were obtained from human femurs (n=48) and bovine tibiae (n=40). Before specimen immersion in different fixation fluids, bone mineral density (BMD) as well as the initial Young's modulus was determined. The Young's modulus was determined in a nondestructive bending test, and measurements were repeated after 6 months of immersion in fixative solution. Subsequent to the nondestructive test, a destructive 3-point bending test was conducted to assess the postyield and fracture properties. The BMD as well as the initial Young's modulus showed no significant differences between the four test groups. After 6 months in fixative solution, the Young's modulus was significantly lowered in human Thiel specimens and only showed minor changes in formalin- and alcohol-glycerine-treated specimens. The plastic energy absorption of human and bovine specimens was altered significantly. Formalin as well as alcohol-glycerine fixation yielded a significant decrease in plastic energy absorption, whereas Thiel fixation significantly increased the plastic energy absorption. Because of the significantly altered plastic mechanical properties of cortical bone, the use fresh-frozen bone specimens is recommended in biomechanical studies investigating failure loads of orthopaedic implants. The use of embalmed specimens should be restricted to pilot tests. Copyright © 2010 Elsevier Inc. All rights reserved.

Effects of stress on alcohol drinking: a review of animal studies

PubMed Central

Lopez, Marcelo F.; Doremus-Fitzwater, Tamara L.

2011-01-01

Rationale While stress is often proposed to play a significant role in influencing alcohol consumption, the relationship between stress and alcohol is complex and poorly understood. Over several decades, stress effects on alcohol drinking have been studied using a variety of animal models and experimental procedures, yet this large body of literature has generally produced equivocal results. Objectives This paper reviews results from animal studies in which alcohol consumption is evaluated under conditions of acute/sub-chronic stress exposure or models of chronic stress exposure. Evidence also is presented indicating that chronic intermittent alcohol exposure serves as a stressor that consequently influences drinking. Results The effects of various acute/sub-chronic stress procedures on alcohol consumption have generally been mixed, but most study outcomes suggest either no effect or decreased alcohol consumption. In contrast, most studies indicate that chronic stress, especially when administered early in development, results in elevated drinking later in adulthood. Chronic alcohol exposure constitutes a potent stressor itself, and models of chronic intermittent alcohol exposure reliably produce escalation of voluntary alcohol consumption. Conclusions A complex and dynamic interplay among a wide array of genetic, biological, and environmental factors govern stress responses, regulation of alcohol drinking, and the circumstances in which stress modulates alcohol consumption. Suggestions for future directions and new approaches are presented that may aid in developing more sensitive and valid animal models that not only better mimic the clinical situation, but also provide greater understanding of mechanisms that underlie the complexity of stress effects on alcohol drinking.

Prenatal alcohol use: the role of lifetime problems with alcohol, drugs, depression, and violence.

PubMed

Flynn, Heather A; Chermack, Stephen T

2008-07-01

The purpose of this study was to examine a broader array of lifetime factors that theoretically may be associated with prenatal alcohol use than have previously been studied together, including family history of alcohol-use problems, history of physical or sexual abuse, lifetime major depressive disorder, alcohol-use disorder, illicit-drug-use problems, and partner violence. A total of 186 pregnant women, all of whom used alcohol in the year before pregnancy, were initially recruited in prenatal care settings. Women who reported no prenatal alcohol use (n = 96) were compared with women who drank 1-10 standard drinks during pregnancy (n = 75) and with women who drank more than 10 standard drinks during pregnancy (n = 13), considered to be a higher risk group, on the lifetime risk variables. Because of the public health implications, secondary analyses compared women who abstained during pregnancy with those who used any alcohol. Significant intercorrelations were found among most of the lifetime risk factors studied. Multivariate analyses showed that drug-use problems and partner violence were most strongly associated with prenatal alcohol use than any other variable studied. Consistent with a life span risk framework for alcohol-use problems, results of this study show that childhood abuse, familial alcoholism, lifetime major depressive disorder, and alcohol- and drug-use problems are interrelated. However, when considered together, only lifetime partner violence and drug use are significantly related to various levels of prenatal alcohol use. Identification, assessment, and intervention efforts should integrate these important factors.

It is generally agreed that traditional alcohol biomarkers lack in sensitivity to detect hazardous alcohol consumption. The present study was undertaken to evaluate the ability of phosphatidylethanol (PEth) and traditional alcohol markers to detect moderate alcohol consumption and to distinguish between moderate alcohol consumption and abstinence. Forty-four subjects, 32 females and 12 males, were included in the study. They were randomized to alcohol abstention or to alcohol consumption. Female participants consumed 150 ml of red wine (equivalent to 16 g of alcohol) per 24 h and the male participants double the amount. The study lasted for 3 months. Blood samples were drawn at the start and at the end of the study period. Blood samples were analysed for PEth, carbohydrate-deficient transferrin (CDT), mean corpuscular volume (MCV), γ-glutamyltransferase (GGT), aspartate aminotransferase (AST) and alanine aminotransferase (ALT). ROC curves for the various biochemical markers were plotted in order to assess their ability to discriminate between abstention and moderate daily consumption of alcohol. PEth and CDT were the only markers with AUROCs significantly higher than 0.5, and PEth was detected in all participants randomized to alcohol consumption. PEth was the only marker that could detect moderate intake and the present results also indicate that PEth probably can distinguish moderate alcohol consumption from abstinence. © The Author 2015.

This study examined the associations between unemployment and alcohol-related hospitalization or mortality and to what extent these associations may be confounded by alcohol consumption and alcohol problems before unemployment. The study was based on the Stockholm Public Health Cohort (SPHC), a population-based stratified random sample with a baseline questionnaire in 2002/2003 and record linkages up to year 2011. The final sample in the study consists of 15,841 people aged 18-60 years. Unemployment was defined as any registration at the public employment services during 2003-2005. The outcome was alcohol-related hospitalization and alcohol-related mortality during 2006-2011. Confounders were age, sex, and education, and we further adjusted for baseline alcohol consumption and alcohol-related hospitalization before the study period. Cox proportional hazard models were fit, and associations were expressed as hazard ratios (HRs). In the fully adjusted model, unemployment was associated with an increased risk of alcohol-related hospitalization or mortality, with a more than threefold hazard (HR = 3.38, 95% CI [1.81, 6.31]) compared with no unemployment during the exposure period. There was a moderate attenuating effect of prior alcohol consumption and alcohol-related hospitalization. Any unemployment in 2003-2005 was highly related to having experienced an alcohol-related diagnosis during the 6-year follow-up, even after controlling for risky use of alcohol and prior hospitalization.

Genetics and alcoholism.

Alcohol is widely consumed; however, excessive use creates serious physical, psychological and social problems and contributes to the pathogenesis of many diseases. Alcohol use disorders (that is, alcohol dependence and alcohol abuse) are maladaptive patterns of excessive drinking that lead to serious problems. Abundant evidence indicates that alcohol dependence (alcoholism) is a complex genetic disease, with variations in a large number of genes affecting a person's risk of alcoholism. Some of these genes have been identified, including two genes involved in the metabolism of alcohol (ADH1B and ALDH2) that have the strongest known affects on the risk of alcoholism. Studies continue to reveal other genes in which variants affect the risk of alcoholism or related traits, including GABRA2, CHRM2, KCNJ6 and AUTS2. As more variants are analysed and studies are combined for meta-analysis to achieve increased sample sizes, an improved picture of the many genes and pathways that affect the risk of alcoholism will be possible.

Homeless persons can be considered a vulnerable group and several studies showed in this group an higher prevalence of chronic and infectious diseases, a lower mental health status, and a higher abuse of alcohol. The aim of our study was to investigate the health status of homeless in Padua, Italy, administering a questionnaire composed by SF-36 and EQ-5D. We conducted a cross-sectional study from 15 December 2015 to 15 February 2016. We enrolled in our study 73 homeless persons welcomed in the municipal dorm of Padua. 5 persons refused to participate in the study; 9 had a mental status incompatible with the participation to the study. We administered to the participants a questionnaire composed by three parts: in the first part we asked sociodemographic information (gender, age, nationality, qualification, height and weight) to calculate BMI, time spent at the dorm, period of homelessness, alcohol intake, smoking habit, availability of a general practitioner, emergency room visits in the last year, admissions in the last year, pre-existing conditions and in act, participation in screening programs. The second part was represented by the Short Form 36 questionnaire. The third part by the EQ-5D questionnaire. Our sample was composed by 79% men and 21% women. 54.7% were Italian. The mean age was 48 years. 72.8% were smoker and 60,3% drunk alcohol. In this latter group 28.8% drunk more than 1 liter of wine per day. Non Italian homeless smoke less than the Italian: this difference is statistically significant (OR = 3.7 p = 0.032 ). Only 9 foreigners had a general practitioner compared to 30 Italian homeless: this difference is statistically significant (OR = 60 P < 0.01). 43 of the 59 respondents (72.8 % ) said to suffer from some disease. No one reported a history of tuberculosis. The most represented diseases were pneumonia (30%), myocardial infarction (17%), hepatitis C (13.5%). Participation in screening programs was very low. From the analysis of the SF-36 results, homeless persons obtained lower scores than Italian population. In our study, 40 persons reported a level 2 or 3 in the EQ-5D dimension called "anxiety/ depression". In the EQ visual-analogue scale, the homeless population showed a lower perception of its health status. Compared to the general population, the homeless reported a worse mental health, and this showed that they represent a particularly vulnerable group. Moreover they had a higher percentage of incorrect habits for their health (alcoholism and tobacco addiction), they suffered from chronic conditions, and tended to have a higher frequency of accesses to the emergency rooms. It would be better to improve the state of health of the homeless, through initiatives that could reduce the causes of homelessness, and that could prevent the onset of diseases in this group.

Hand washing and hand antisepsis are proven infection control measures in the school setting, yet barriers such as lack of soap, paper towels, and hand sanitizer can hinder compliance. This pilot study measured the prevalence of hand cleaning supplies in public schools. Ten school districts (93 schools) participated in school nurse inspections. In November 2008, 90 schools (97%) reported their inspection results. Among 697 total bathrooms, 88.8% had soap and 91.7% had paper towels or hand dryers. Hand sanitizer was reported in 1.2% of bathrooms and 15.2% of cafeterias. No difference was observed between boys' and girls' bathrooms, or primary and secondary schools, in the prevalence of soap or paper towels/hand dryers. Hand washing supplies were generally available in public school bathrooms. Alcohol-based hand sanitizer in school bathrooms was reported occasionally and should be discouraged. Hand sanitizer in a supervised setting, the school cafeteria, was not often reported and should be promoted.

Impaired self-control is an important symptom of addictive diseases. The average number of factors improving self-control among 117 men dependent on alcohol, other substances and pathological gamblers was 5.55 (SD=3.5). We classified strategies how to improve self-control into following groups (their ordering reflects the frequency of their use in our sample): 1. The help of others (professional treatment, self-help groups, and family), 2. Distraction and similar techniques, 3. The use of motivation, 4. Life-style changes including appropriate rest, 5. Physical activity, sports, physical work, 6. The use of environments, 7. Mastering of social and other relevant skills, 8. Relaxation based approaches, 9. Techniques working with improved self-awareness, 10. Pharmacotherapy, 11. Acknowledgement of an addictive disease and abstinence, 12. Disrupting risky behavioral patterns. To improve of self-control in addictive diseases simple techniques are appropriate because of temporarily impaired cognitive functions during craving. Frequent repetition are also important.

Nosocomial infections are a concern of growing interest in veterinary medicine. Clipper blades have been confirmed as fomites for numerous potential pathogens and, as such, may be associated with wound and surgical site infections. The goal of this study was to evaluate the disinfectant capabilities of several commonly used clipper blade cleaning products. Seventy sterile clipper blades were inoculated with strains of Pseudomonas aeruginosa , Escherichia coli , and Staphylococcus aureus . Blades were then subjected to one of seven treatment groups for disinfecting. Quantitative cultures of remaining bacteria were performed. All blades in the control group showed large amounts of bacterial recovery. Culture results showed no recovery in blades soaked in alcohol or chlorhexidine or those sprayed with an ethanol/o-phenylphenol product, while moderate recovery was seen with all other treatments. These results show that persistent contamination of clipper blades can occur with the use of several commonly used disinfectant products. Further research is necessary to evaluate fungicidal capabilities as well as the effect of disinfection on clipper blade maintenance.

Objective Despite evidence for detrimental effects of alcohol on sleep quality in laboratory studies, alcohol is commonly used as a self-prescribed sleep aid. This study examined the within-person associations of alcohol use with sleep duration and quality in everyday life to gain insight into the ecological validity of laboratory findings on the association between sleep and alcohol. Method A sample of 150 adults (age 19–89 years) were followed for 60+ days as part of an intensive experience sampling study wherein participants provided daily reports of their alcohol use, sleep duration, and sleep quality. Within-person and between-person associations of daily sleep duration and quality with alcohol use were examined using multilevel models. Results A significant, negative within-person association was observed between sleep quality and alcohol use. Sleep quality was lower on nights following alcohol use. Sleep duration did not vary as a function of within-person variation in alcohol use. Conclusions In line with laboratory assessments, alcohol use was associated with low sleep quality but was not associated with sleep duration, suggesting that laboratory findings generalize to everyday life. This examination of individuals’ daily lives suggests that alcohol does not systematically improve sleep quality or duration in real life. PMID:27249804

Unplanned Drinking and Alcohol-Related Problems: A Preliminary Test of the Model of Unplanned Drinking Behavior

Pearson, Matthew R.; Henson, James M.

Much research links impulsivity with alcohol use and problems. In two studies, unplanned (or impulsive) drinking is assessed directly to determine whether it has direct effects on alcohol use and alcohol-related problems. In study 1, we examined whether unplanned drinking serves as a proximal mediator of the effects of impulsivity-like traits on alcohol-related outcomes. With a sample of 211 college student drinkers, we found that the Unplanned Drinking Scale was significantly related to alcohol use, and perhaps more importantly, had a direct effect on alcohol-related problems even after controlling for frequency and quantity of alcohol use. Further, unplanned drinking partially mediated the effects of negative urgency on alcohol-related problems. In study 2, we examined whether unplanned drinking accounts for unique variance in alcohol-related outcomes when controlling for use of protective behavioral strategies. With a sample of 170 college students, we replicated the findings of Study 1 in that the Unplanned Drinking Scale had a significant direct effect on alcohol-related problems even after controlling for alcohol use; further, this effect was maintained when controlling for use of protective behavioral strategies. Limitations include the modest sample sizes and the cross-sectional design. Future directions for testing the Model of Unplanned Drinking Behavior are proposed. PMID:23276312

Elevated Behavioral Economic Demand for Alcohol in a Community Sample of Heavy Drinking Smokers.

Cigarette smokers are more likely to consume alcohol at higher levels and experience poorer response to treatment for alcohol problems than are nonsmokers. One previous study in university students suggests that a potential reason for the high overlap between alcohol and tobacco use is that concurrent smoking is associated with overvaluation of alcohol, as reflected in elevated behavioral economic demand. The present study sought to extend these initial findings in a community sample with heavier levels of alcohol and tobacco use. Participants were 111 non-treatment-seeking heavy drinkers(defined as 18+/14+ drinks per week for men/women) from a larger study on alcohol pharmacotherapy mechanisms. Forty-nine participants (44%) reported regular smoking (≥5 cigarettes/day). Participants completed a hypothetical alcohol purchase task assessing alcohol consumption at escalating levels of price. Covariates included demographics, drinking quantity, alcohol use disorder severity, depression, and delay discounting. In covariate-adjusted models, smokers reported significantly higher maximum alcohol expenditures (O max ) and breakpoint price (first price suppressing consumption to zero) compared with nonsmokers. Elevated alcohol demand correlated with drinking quantity and severity in the entire sample, but not with smoking frequency or nicotine dependence among smokers only. This study offers further evidence of increased reinforcing value of alcohol among smokers in a sample of heavy drinkers from the community. Clinical implications and potential mechanisms underlying this relationship are discussed.

Prior studies of the relationship between socioeconomic status (SES) and alcohol consumption and problems in adolescence have been inconclusive. Few studies have examined all three major SES indicators and a broad range of alcohol-related outcomes at different ages. In the Avon Longitudinal Study of Parents and Children cohort, we examined (by logistic regression, with differential weighting to control for attrition) the relationship between family income and parental education and occupational status, and five alcohol outcomes assessed at ages 16 and 18 years. At age 16, high SES-as indexed by income and education-significantly predicted frequent alcohol consumption. Low SES-as measured by education and occupational status-predicted alcohol-related problems. At age 18, high SES-particularly income and education-significantly predicted frequent alcohol consumption and heavy episodic drinking and, more weakly, symptoms of alcohol dependence. All three measures of SES were inversely related to high-quantity consumption and alcohol behavioral problems. In adolescents in the United Kingdom, the relationship between SES and alcohol-related behaviors is complex and varies as a function of age, SES measure, and specific outcome. High SES tends to predict increased consumption and, in later adolescence, heavy episodic drinking and perhaps symptoms of alcohol dependence. Low SES predicts alcohol-related behavioral problems and, in later adolescence, high-quantity alcohol consumption.

Reflections on science and the governance of alcohol policy.

To consider, briefly, science's role in informing alcohol policy, and how science could help reframe the present governance of alcohol policy. Expression of the two project coordinators' reflections based on discussions during project meetings of the Alcohol Measures for Public Health Research Alliance (AMPHORA) project. Three endeavours are considered important for science's role in informing alcohol policy: modelling studies that help predict the outcomes of differing policy approaches; studying the impact of live policy changes as a powerful set of natural experiments; and, improved study of the impact of integrated, coordinated and joined up alcohol policies, as opposed to the impact of individual alcohol policy measures. Three areas where science can contribute to strengthened alcohol policy governance include: analysis of different governance architectures that might promote joined-up actions between different sectors; the design of better metrics that measure the impact of public and private sector actions on health; and, by identifying incentives that help consumers make choices on the use of alcohol that improve health. The impact of science on better alcohol policy governance can only happen if there is more and better dialogue between scientists and those who design alcohol policy. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

Alcohol consumption and risk of type 2 diabetes mellitus in Japanese: a systematic review.

To evaluate the association between alcohol consumption and the risk for type 2 diabetes (DM) in Japanese. We searched the MEDLINE data base with the key words 'alcohol intake' (or 'alcohol consumption') and 'Japanese' cross-linked with 'diabetes mellitus' (or 'impaired glucose tolerance'). The reports we sought were restricted to prospective cohort studies, randomized controlled trials, meta-analyses and systematic reviews. Computerized and hand searches were conducted in June 2007. Seven prospective cohort studies were adopted. We previously reported that in lean Japanese men (BMI < or =22.0 kg/m2), moderate to heavy alcohol intake is a risk factor for diabetes. One study found heavy alcohol intake to be associated with an increased risk in low-BMI men while moderate alcohol intake was associated with a reduced risk in higher-BMI men. Another study suggested daily alcohol consumption to be a risk factor in low-BMI participants, while being protective in middle-BMI participants. Yet another study demonstrated a U-shaped association between alcohol consumption and the risk of diabetes in men. Three other studies, which did not divide the subjects in terms of BMI values, indicated alcohol intake to be an increased risk for diabetes, two being in men and one being in women, respectively. For a large number of Japanese men who have relatively low BMI, alcohol intake is an established risk factor for diabetes.
