    Introduction Early identification (EI) and brief interventions (BIs) for risky drinkers are effective tools in primary care. Lack of time in daily practice has been identified as one of the main barriers to implementation of BI. There is growing evidence that facilitated access by primary healthcare professionals (PHCPs) to a web-based BI can be a time-saving alternative to standard face-to-face BIs, but there is as yet no evidence about the effectiveness of this approach relative to conventional BI. The main aim of this study is to test non-inferiority of facilitation to a web-based BI for risky drinkers delivered by PHCP against face-to-face BI. Method and analysis A randomised controlled non-inferiority trial comparing both interventions will be performed in primary care health centres in Catalonia, Spain. Unselected adult patients attending participating centres will be given a leaflet inviting them to log on to a website to complete the Alcohol Use Disorders Identification Test (AUDIT-C) alcohol screening questionnaire. Participants with positive results will be requested online to complete a trial module including consent, baseline assessment and randomisation to either face-to-face BI by the practitioner or BI via the alcohol reduction website. Follow-up assessment of risky drinking will be undertaken online at 3 months and 1 year using the full AUDIT and D5-EQD5 scale. Proportions of risky drinkers in each group will be calculated and non-inferiority assessed against a specified margin of 10%. Assuming reduction of 30% of risky drinkers receiving standard intervention, 1000 patients will be required to give 90% power to reject the null hypothesis. Ethics and dissemination The protocol was approved by the Ethics Commmittee of IDIAP Jordi Gol i Gurina P14/028. The findings of the trial will be disseminated through peer-reviewed journals, national and international conference presentations. Trial registration number ClinicalTrials.gov NCT02082990. PMID

    Aims: In 2011, online marketing became the largest marketing channel in the UK, overtaking television for the first time. This study aimed to describe the exposure of children and young adults to alcohol marketing on social media websites in the UK. Methods: We used commercially available data on the three most used social media websites among young people in the UK, from December 2010 to May 2011. We analysed by age (6–14 years; 15–24 years) and gender the reach (proportion of internet users who used the site in each month) and impressions (number of individual pages viewed on the site in each month) for Facebook, YouTube and Twitter. We further analysed case studies of five alcohol brands to assess the marketer-generated brand content available on Facebook, YouTube and Twitter in February and March 2012. Results: Facebook was the social media site with the highest reach, with an average monthly reach of 89% of males and 91% of females aged 15–24. YouTube had a similar average monthly reach while Twitter had a considerably lower usage in the age groups studied. All five of the alcohol brands studied maintained a Facebook page, Twitter page and YouTube channel, with varying levels of user engagement. Facebook pages could not be accessed by an under-18 user, but in most cases YouTube content and Twitter content could be accessed by those of all ages. Conclusion: The rise in online marketing of alcohol and the high use of social media websites by young people suggests that this is an area requiring further monitoring and regulation. PMID:24293506

    Since the 1990s, we have suggested the concept of pre-alcoholism which encompasses patients who have drunk a great deal of alcohol leading to alcohol related problems such as health issues, domestic violence, drunken driving and black-outs. Pre-alcoholism excludes alcohol-dependent patients who have experienced continuous drinking or withdrawal symptoms. We have treated many outpatients with pre-alcoholism for several years. Our regimen demands that the patients must be abstinent for half a year at the beginning of their treatment. After half a year they can choose whether they will continue to be abstinent or they will resume drinking with the aim of reducing their total alcohol consumption. The study clarified the character of pre-alcoholism by investigation of the patients' background and re-diagnosis of the patients based on the International Classification of Diseases, 10th Revision (ICD-10). A remarkable ratio of pre-alcoholic patients was diagnosed with alcohol dependence under ICD-10. We classified pre-alcoholic patients into two groups, one diagnosed as having ICD-10-classed alcohol dependence and the other which did not fulfill the ICD-10 diagnostic criteria of alcohol dependence, and examined the therapeutic processes of the two groups. It was shown that most pre-alcoholic patients could finally take required courses of treatment by themselves without regard to diagnosis under ICD-10, even if they chose any treatment and made alcohol related mistakes on the way. Our findings suggested that pre-alcoholic patients, a portion of whom may have exhibited mild alcohol dependence, could select drinking reduction as a primary goal of treatment after a certain period of abstinence.

    Based on the knowledge that alcohol misuse causes a multitude of diseases and increased mortality, this systematic review examines whether a reduction of the individual alcohol consumption can contribute to a minimization of health risks within a harm reduction approach. In fact, the reviewed 63 studies indicate that interventions aiming at alcohol reduction (including total abstinence as one possible therapeutic aim) indeed resulted in or were associated with positive effects in harmful, hazardous or alcohol-dependent drinkers. Major benefits were observed for reducing alcohol-associated injuries, recovery of ventricular heart function in alcoholic cardiomyopathy, blood pressure lowering, normalization of biochemical parameter, body weight reduction, histological improvement in pre-cirrhotic alcohol-related liver disease and slowed progression of an already existing alcohol-attributable liver fibrosis. Furthermore, reduced withdrawal symptoms, prevalence of psychiatric episodes and duration of in-patient hospital days, improvement of anxiety and depression symptoms, self-confidence, physical and mental quality of life, fewer alcohol-related adverse consequences as well as lower psychosocial stress levels and better social functioning can result from reduced alcohol intake. The reviewed literature demonstrated remarkable socioeconomic cost benefits in areas such as the medical health-care system or workforce productivity. Individuals with heightened vulnerability further benefit significantly from alcohol reduction (e.g. hypertension, hepatitis C, psychiatric co-morbidities, pregnancy, but also among adolescents and young adults). Concluding, the reviewed studies strongly support and emphasize the importance and benefits of early initial screening for problematic alcohol use followed by brief and other interventions in first contact medical health-care facilities to reduce alcohol intake.

    Background Methadone-Maintained (MM) clients who engage in excessive alcohol use are at high risk for HIV and Hepatitis B virus (HBV) infection. Nurse-led Hepatitis Health Promotion (HHP) may be one strategy to decrease alcohol use in this population. Objective To evaluate the impact of nurse-led HHP, delivered by nurses compared to Motivational Interviewing (MI), delivered by trained therapists in group sessions or one-on-one on reduction of alcohol use. Methods A three-arm randomized, controlled trial, conducted with 256 MM adults attending one of five MM outpatient clinics in the Los Angeles area. Within each site, moderate-to-heavy alcohol-using MM participants were randomized into one of three conditions: 1) nurse-led hepatitis health promotion group sessions (n=87); 2) MI delivered in group sessions (MI-group; n=90), or 3) MI delivered one-on-one sessions (MI-single, n=79). Results Self-reported alcohol use was reduced from a median of 90 drinks/month at baseline to 60 drinks/month at six month follow-up. A Wilcoxon sign-rank test indicated a significant reduction in alcohol use in the total sample (p < .05). In multiple logistic regression analysis controlling for alcohol consumption at baseline and other covariates, no differences by condition were found. Discussion As compared to two programs delivered by MI specialists, a culturally-sensitive and easy to implement nurse-led HHP program produced similar reductions in alcohol use over six months. Employing nurse-led programs may allow cost savings for treatment programs as well as a greater integration of alcohol reduction counseling along with a more comprehensive focus on general health-related issues than previously conducted.

    Alcohol use during young adulthood may reflect a learning process whereby positive and negative alcohol-related experiences and interpretations of those experiences drive subsequent behavior. Understanding the effect of consequences and the evaluation of consequences could be informative for intervention approaches. Objective To examine the extent to which the number of positive and negative alcohol consequences experienced and the evaluation of those consequences predict subsequent alcohol use and consequences in college students. Method Students at three colleges (N = 679) completed biweekly web-based surveys on alcohol use, positive and negative consequences, and consequence evaluations for two academic years. Hierarchical linear modeling tested whether consequences and evaluations in a given week predicted changes in alcohol use and consequences at the next assessment. Moderation by gender and class year also were evaluated. Results Evaluating past-week negative consequences more negatively than one’s average resulted in decreases in alcohol use at the next assessment. More negative evaluation of negative consequences was followed in the subsequent observation by a higher number of positive consequences for females but not males. A higher number of positive consequences in a given week was followed by a higher number of both positive and negative consequences in the subsequent observation. Number of negative consequences experienced and evaluation of positive consequences had no effect on later behavior. Conclusions Salient negative consequences may drive naturalistic reductions in alcohol use, suggesting the possible efficacy of programs designed to increase the salience of the negative effects of alcohol.

    Alcohol abuse is one of the most important risk factors for health and is a major cause of death and morbidity. Despite this, only about one-tenth of individuals with alcohol abuse disorders receive therapeutic intervention and specific rehabilitation. Among the various dichotomies that limit an effective approach to the problem of alcohol use disorder treatment, one of the most prominent is integrated treatment versus harm reduction. For years, these two divergent strategies have been considered to be opposite poles of different philosophies of intervention. One is bound to the search for methods that aim to lead the subject to complete abstinence; the other prioritizes a progressive decline in substance use, with maximum reduction in the damage that is correlated with curtailing that use. Reduction of alcohol intake does not require any particular setting, but does require close collaboration between the general practitioner, specialized services for addiction, alcohology services and psychiatry. In patients who reach that target, significant savings in terms of health and social costs can be achieved. Harm reduction is a desirable target, even from an economic point of view. At the present state of neuroscientific knowledge, it is possible to go one step further in the logic that led to the integration of psychosocial and pharmacological approaches, by attempting to remove the shadows of social judgment that, at present, are aiming for a course of treatment that is directed towards absolute abstention.

    Objectives The objective of the present study was to explore whether the possibility of offering facilitated access to an alcohol electronic brief intervention (eBI) instead of delivering brief face-to-face advice increased the proportion of consulting adults who were screened and given brief advice. Design The study was a 12-week implementation study. Sixty primary healthcare units (PHCUs) in 5 jurisdictions (Catalonia, England, the Netherlands, Poland and Sweden) were asked to screen adults who attended the PHCU for risky drinking. Setting A total of 120 primary healthcare centres from 5 jurisdictions in Europe. Participants 746 individual providers (general practitioners, nurses or other professionals) participated in the study. Primary outcome Change in the proportion of patients screened and referred to eBI comparing a baseline 4-week preimplementation period with a 12-week implementation period. Results The possibility of referring patients to the eBI was not found to be associated with any increase in the proportion of patients screened. However, it was associated with an increase in the proportion of screen-positive patients receiving brief advice from 70% to 80% for the screen-positive sample as a whole (p<0.05), mainly driven by a significant increase in brief intervention rates in England from 87% to 96% (p<0.01). The study indicated that staff displayed a low level of engagement in this new technology. Staff continued to offer face-to-face advice to a larger proportion of patients (54%) than referral to eBI (38%). In addition, low engagement was seen among the referred patients; on average, 18% of the patients logged on to the website with a mean log-on rate across the different countries between 0.58% and 36.95%. Conclusions Referral to eBI takes nearly as much time as brief oral advice and might require more introduction and training before staff are comfortable with referring to eBI.

    Primary alcohols can be deoxygenated cleanly and in high yield by reduction of derived diphenyl phosphate esters with lithium triethylborohydride in tetrahydrofuran at room temperature. Selective deoxygenation of a primary alcohol in the presence of a secondary alcohol was demonstrated. The two-step process can be performed in one pot, making it both simple and convenient.

    2007-01-01

    In an effort to identify groups who may be more vulnerable to tension-reduction drinking (Frone, 2003), we examine whether drinking alcohol in response to work stress varies as a function of whether workers were raised in homes where (a) both parents abstained from alcohol, (b) at least one parent drank nonproblematically, (c) at least one parent drank problematically, or (d) both parents drank problematically. Employees participating in a large, longitudinal study who reported using alcohol in the previous year (N=895) completed various measures of work stressors, alcohol use, and alcohol problems. We found few mean group differences for either the work stressor or alcohol measures, but we did find a greater number of significant and moderate correlations between work stressors and alcohol for those reporting that both parents drank alcohol problematically. Interestingly, a number of significant correlations were found for those reporting that both parents abstained from alcohol; few were found for the two groups reporting that at least one parent drank with or without alcohol problems. Results are interpreted in light of where and how alcohol expectancies and other coping methods are learned. PMID:17658697

  13. Determinants of underage college student drinking: implications for four major alcohol reduction strategies.

    Paek, Hye-Jin; Hove, Thomas

    2012-01-01

    Guided by the assumptions of the social ecological model and the social marketing approach, this study provides a simultaneous and comprehensive assessment of 4 major alcohol reduction strategies for college campuses: school education programs, social norms campaigns, alcohol counter-marketing, and alcohol control policies. Analysis of nationally representative secondary survey data among 5,472 underage students reveals that alcohol marketing seems to be the most formidable risk factor for underage drinking, followed by perceived drinking norms (injunctive norm) and lax policy enforcement. This analysis suggests that, to make social norms campaigns and alcohol control policies more effective, alcohol reduction strategies should be developed to counter the powerful influence of alcohol marketing and promotions.

  14. Asymmetric reduction and oxidation of aromatic ketones and alcohols using W110A secondary alcohol dehydrogenase from Thermoanaerobacter ethanolicus.

    An enantioselective asymmetric reduction of phenyl ring-containing prochiral ketones to yield the corresponding optically active secondary alcohols was achieved with W110A secondary alcohol dehydrogenase from Thermoanaerobacter ethanolicus (W110A TESADH) in Tris buffer using 2-propanol (30%, v/v) as cosolvent and cosubstrate. This concentration of 2-propanol was crucial not only to enhance the solubility of hydrophobic phenyl ring-containing substrates in the aqueous reaction medium, but also to shift the equilibrium in the reduction direction. The resulting alcohols have S-configuration, in agreement with Prelog's rule, in which the nicotinamide-adenine dinucleotide phosphate (NADPH) cofactor transfers its pro-R hydride to the re face of the ketone. A series of phenyl ring-containing ketones, such as 4-phenyl-2-butanone (1a) and 1-phenyl-1,3-butadione (2a), were reduced with good to excellent yields and high enantioselectivities. On the other hand, 1-phenyl-2-propanone (7a) was reduced with lower ee than 2-butanone derivatives. (R)-Alcohols, the anti-Prelog products, were obtained by enantiospecific oxidation of (S)-alcohols through oxidative kinetic resolution of the rac-alcohols using W110A TESADH in Tris buffer/acetone (90:10, v/v).

    Binge alcohol consumption in adolescents is increasing, and studies in animal models show that adolescence is a period of high vulnerability to brain insults. The purpose of the present study was to determine the deleterious effects of binge alcohol on hippocampal neurogenesis in adolescent nonhuman primates. Heavy binge alcohol consumption over 11 mo dramatically and persistently decreased hippocampal proliferation and neurogenesis. Combinatorial analysis revealed distinct, actively dividing hippocampal neural progenitor cell types in the subgranular zone of the dentate gyrus that were in transition from stem-like radial glia-like cells (type 1) to immature transiently amplifying neuroblasts (type 2a, type 2b, and type 3), suggesting the evolutionary conservation of milestones of neuronal development in macaque monkeys. Alcohol significantly decreased the number of actively dividing type 1, 2a, and 2b cell types without significantly altering the early neuronal type 3 cells, suggesting that alcohol interferes with the division and migration of hippocampal preneuronal progenitors. Furthermore, the lasting alcohol-induced reduction in hippocampal neurogenesis paralleled an increase in neural degeneration mediated by nonapoptotic pathways. Altogether, these results demonstrate that the hippocampal neurogenic niche during adolescence is highly vulnerable to alcohol and that alcohol decreases neuronal turnover in adolescent nonhuman primate hippocampus by altering the ongoing process of neuronal development. This lasting effect, observed 2 mo after alcohol discontinuation, may underlie the deficits in hippocampus-associated cognitive tasks that are observed in alcoholics.

    Modified electrodes using immobilized alcohol dehydrogenase enzymes for the efficient electroreduction of butyraldehyde to butanol are presented as an important step for the utilization of CO2-reduction products. Alcohol dehydrogenase was immobilized, embedded in an alginate–silicate hybrid gel, on a carbon felt (CF) electrode. The application of this enzyme to the reduction of an aldehyde to an alcohol with the aid of the coenzyme nicotinamide adenine dinucleotide (NADH), in analogy to the final step in the natural reduction cascade of CO2 to alcohol, has been already reported. However, the use of such enzymatic reductions is limited because of the necessity of providing expensive NADH as a sacrificial electron and proton donor. Immobilization of such dehydrogenase enzymes on electrodes and direct pumping of electrons into the biocatalysts offers an easy and efficient way for the biochemical recycling of CO2 to valuable chemicals or alternative synthetic fuels. We report the direct electrochemical addressing of immobilized alcohol dehydrogenase for the reduction of butyraldehyde to butanol without consumption of NADH. The selective reduction of butyraldehyde to butanol occurs at room temperature, ambient pressure and neutral pH. Production of butanol was detected by using liquid-injection gas chromatography and was estimated to occur with Faradaic efficiencies of around 40 %. PMID:26113881

    Objective To evaluate the psychometric properties of a new self-report questionnaire designed to assess college students’ intentions to employ 31 specific alcohol-reduction strategies. Method Students attending a large public university were recruited to complete alcohol-reduction, drinking history, and personality questionnaires online. Results Based on item-total correlations and principal components analysis, we eliminated three items and calculated average intention ratings across the remaining 28 items. The resulting scale had appropriate unidimensionality and excellent internal consistency. Correlations of intention questionnaire scores with measures of drinking history, alcohol outcome expectancies, sensation seeking, and impression management provided some support for criterion and discriminant validity of the questionnaire. Conclusion This questionnaire could be employed as an outcome measure to evaluate prevention programs and as a clinical tool to identify clients who have little intention to employ drinking reduction strategies in heavy drinking situations.

    2013-01-01

    Objectives. We took advantage of a natural experiment to assess the impact on suicide mortality of a suite of Russian alcohol policies. Methods. We obtained suicide counts from anonymous death records collected by the Russian Federal State Statistics Service. We used autoregressive integrated moving average (ARIMA) interrupted time series techniques to model the effect of the alcohol policy (implemented in January 2006) on monthly male and female suicide counts between January 2000 and December 2010. Results. Monthly male and female suicide counts decreased during the period under study. Although the ARIMA analysis showed no impact of the policy on female suicide mortality, the results revealed an immediate and permanent reduction of about 9% in male suicides (Ln ω0 = −0.096; P = .01). Conclusions. Despite a recent decrease in mortality, rates of alcohol consumption and suicide in Russia remain among the highest in the world. Our analysis revealed that the 2006 alcohol policy in Russia led to a 9% reduction in male suicide mortality, meaning the policy was responsible for saving 4000 male lives annually that would otherwise have been lost to suicide. Together with recent similar findings elsewhere, our results suggest an important role for public health and other population level interventions, including alcohol policy, in reducing alcohol-related harm.

    The effects of setting goals on goal commitment, self-efficacy for goal achievement, and goal achievement in the context of an alcohol use intervention were examined using an experimental design in which participants were randomized to participatively set goals, assigned goals, and no goal conditions. One hundred and twenty-six heavy-drinking college students received a single cognitive-behavioral assessment/intervention session and completed measures of goal commitment, self-efficacy for goal achievement, and alcohol use. Results were consistent with, and expanded upon, previous research by demonstrating that having a goal for limiting alcohol consumption was predictive of lower quantity and frequency of alcohol use relative to not having a goal. Participation in goal setting yielded greater goal commitment and self-efficacy for goal achievement than assigned goals, but did not result in significantly greater reductions in alcohol use relative to assigned goals. Goal commitment and self-efficacy explained unique variance in the prediction of alcohol use at follow-up. Findings support the importance of goal setting in alcohol interventions and suggest areas for further research.

    The regioselective reductive hydration of terminal alkynes using two complementary dual catalytic systems is described. Branched or linear alcohols are obtained in 75-96% yield with ≥25:1 regioselectivity from the same starting materials. The method is compatible with terminal, di-, and trisubstituted alkenes. This reductive hydration constitutes a strategic surrogate to alkene oxyfunctionalization and may be of utility in multistep settings.

    Background Cigarette taxation has been recognized as one of the most significant policy instruments to reduce smoking. Smoking and drinking are highly comorbid behaviors, and the public health benefits of cigarette taxation may extend beyond smoking-related outcomes to impact alcohol consumption. The current study is the first to test whether increases in cigarette taxes are associated with reductions in alcohol consumption among smokers using a large, prospective U.S. sample. Method Our sample included 21,473 alcohol consumers from the National Epidemiological Survey on Alcohol and Related Conditions (NESARC). Multiple linear regression analyses were conducted to evaluate whether increases in cigarette taxes between Waves I (2001–2002) and II (2004–2005) were associated with reductions in quantity and frequency of alcohol consumption, adjusting for demographics, baseline alcohol consumption, and alcohol price. Stratified analyses were conducted by sex, hazardous drinking status, and age and income group. Results Increases in cigarette taxes were associated with modest reductions in typical quantity of alcohol consumption and frequency of binge drinking among smokers. Cigarette taxation was not associated with changes in alcohol consumption among non-smokers. In analyses stratified by sex, the inverse associations of cigarette taxes with typical quantity and binge drinking frequency were found only for male smokers. Further, the inverse association of cigarette taxation and alcohol consumption was stronger among hazardous drinkers (translating into approximately 1/2 a drink less alcohol consumption per episode), young adult smokers, and smokers in the lowest income category. Conclusions Findings from this longitudinal, epidemiological study suggest increases in cigarette taxes are associated with modest to moderate reductions in alcohol consumption among vulnerable groups. Additional research is needed to further quantify the public health benefits of cigarette

  11. Changes in volatile composition and sensory attributes of wines during alcohol content reduction.

    A desirable sensory profile is a major consumer driver for wine acceptability and should be considered during the production of reduced alcohol wines. Although various viticultural practices and microbiological approaches show promising results, separation technologies such as membrane filtration, in particular reverse osmosis, evaporative perstraction, and vacuum distillation represent the most common commercial methods used to produce reduced alcohol wine. However, ethanol removal from wine can result in a significant loss of volatile compounds such as esters (ethyl octanoate, ethyl acetate, isoamyl acetate) that contribute positively to the overall perceived aroma. These losses can potentially reduce the acceptability of the wine to consumers and decrease their willingness to purchase wines that have had their alcohol level reduced. The change in aroma as a result of the ethanol removal processes is influenced by a number of factors: the type of alcohol reduction process; the chemical-physical properties (volatility, hydrophobicity, steric hindrance) of the aroma compounds; the retention properties of the wine non-volatile matrix; and the ethanol level. This review identifies and summarises possible deleterious influences of the dealcoholisation process and describes best practice strategies to maintain the original wine composition.

  12. Secondary alcohol dehydrogenase catalyzes the reduction of exogenous acetone to 2-propanol in Trichomonas vaginalis.

    Secondary alcohols such as 2-propanol are readily produced by various anaerobic bacteria that possess secondary alcohol dehydrogenase (S-ADH), although production of 2-propanol is rare in eukaryotes. Specific bacterial-type S-ADH has been identified in a few unicellular eukaryotes, but its function is not known and the production of secondary alcohols has not been studied. We purified and characterized S-ADH from the human pathogen Trichomonas vaginalis. The kinetic properties and thermostability of T. vaginalis S-ADH were comparable with bacterial orthologues. The substantial activity of S-ADH in the parasite's cytosol was surprising, because only low amounts of ethanol and trace amounts of secondary alcohols were detected as metabolic end products. However, S-ADH provided the parasite with a high capacity to scavenge and reduce external acetone to 2-propanol. To maintain redox balance, the demand for reducing power to metabolize external acetone was compensated for by decreased cytosolic reduction of pyruvate to lactate and by hydrogenosomal metabolism of pyruvate. We speculate that hydrogen might be utilized to maintain cytosolic reducing power. The high activity of Tv-S-ADH together with the ability of T. vaginalis to modulate the metabolic fluxes indicate efficacious metabolic responsiveness that could be advantageous for rapid adaptation of the parasite to changes in the host environment.

    Alcohol dehydrogenases (ADHs) are enzymes that catalyze the reversible reduction of carbonyl compounds to their corresponding alcohols. We have been studying a thermostable, nicotinamide-adenine dinucleotide phosphate (NADP(+))-dependent, secondary ADH from Thermoanaerobacter ethanolicus (TeSADH). In the current work, we expanded our library of TeSADH and adopted the site-saturation mutagenesis approach in creating a comprehensive mutant library at W110. We used phenylacetone as a model substrate to study the effectiveness of our library because this substrate showed low enantioselectivity in our previous work when reduced using W110A TeSADH. Five of the newly designed W110 mutants reduced phenylacetone at >99.9% ee, and two of these mutants exhibit an enantiomeric ratio (E-value) of over 100. These five mutants also reduced 1-phenyl-2-butanone and 4-phenyl-2-butanone to their corresponding (S)-configured alcohols in >99.9% ee. These new mutants of TeSADH will likely have synthetic utility for reduction of aromatic ketones in the future.

    HIV-infected patients have considerable need for alcohol reduction support, and HIV care providers are strategically placed to implement a “prevention for positives” alcohol reduction approach through alcohol screening and brief interventions (SBIs). To facilitate this approach, we provided alcohol SBI education and training to HIV care providers in four hospital-based, New York City HIV Care Centers in 2007. Interviews with the medical directors and 14 of the HIV care providers who attended the training identified barriers to implementing alcohol SBIs. These included limited time for alcohol screening, patients’ incomplete disclosure of alcohol use, providers’ perceptions that alcohol use is not a major problem for their patients, and provider specialization that assigns patients with problematic alcohol use to specifically designated providers. Identified facilitators for alcohol SBI implementation included adequate time to conduct the SBI; availability of information, tools, and key points to emphasize with HIV-infected patients; and use of a brief alcohol screening tool.

    One of the foremost challenges in lignocellulose conversion encompasses the integration of effective lignin valorization in current carbohydrate-oriented biorefinery schemes. Catalytic reductive fractionation (CRF) of lignocellulose offers a technology to simultaneously produce lignin-derived platform chemicals and a carbohydrate-enriched pulp via the combined action of lignin solvolysis and metal-catalyzed hydrogenolysis. Herein, the solvent (composition) plays a crucial role. In this contribution, we study the influence of alcohol/water mixtures by processing poplar sawdust in varying MeOH/water and EtOH/water blends. The results show particular effects that strongly depend on the applied water concentration. Low water concentrations enhance the removal of lignin from the biomass, while the majority of the carbohydrates are left untouched (scenario A). Contrarily, high water concentrations favor the solubilization of both hemicellulose and lignin, resulting in a more pure cellulosic residue (scenario B). For both scenarios, an evaluation was made to determine the most optimal solvent composition, based on two earlier introduced empirical efficiency descriptors (denoted LFDE and LFFE). According to these measures, 30 (A) and 70 vol % water (B) showed to be the optimal balance for both MeOH/water and EtOH/water mixtures. This successful implementation of alcohol/water mixtures allows operation under milder processing conditions in comparison to pure alcohol solvents, which is advantageous from an industrial point of view.

    Visual attention problems have been reported in association with prenatal alcohol exposure (PAE). With related behavioral data documented in literature, further investigation of this PAE effect would benefit from integrating functional and anatomical imaging data to ascertain its neurobiological basis. The current study investigated the possible functional and anatomical bases for the PAE-related visual sustained attention deficit. Functional magnetic resonance imaging (fMRI) data were collected while the subjects performed a sustained visual attention task. High resolution, three dimensional anatomical images were also collected for morphometric evaluation. In the alcohol-affected subjects, we observed a significant white and gray matter volume reduction in the occipital-temporal area. Meanwhile, their fMRI activations in the same region resided more superiorly than that of the controls resulting in reduced activation in the ventral occipital-temporal area. The location of this PAE functional abnormality approximately matches that of the significant structural reduction. In addition to the well documented corpus callosum abnormalities observed in PAE subjects, the present results reveal a teratogenic effect on the occipital-temporal area. Furthermore, as the occipital-temporal area plays an important role in visual attention, the current observation suggests a neurobiological underpinning for the PAE related deficit in sustained visual attention.

  20. The Huge Reduction in Adult Male Mortality in Belarus and Russia: Is It Attributable to Anti-Alcohol Measures?

    PubMed Central

    2015-01-01

    Background and Aim Harmful alcohol consumption has long been recognized as being the major determinant of male premature mortality in the European countries of the former USSR. Our focus here is on Belarus and Russia, two Slavic countries which continue to suffer enormously from the burden of the harmful consumption of alcohol. However, after a long period of deterioration, mortality trends in these countries have been improving over the past decade. We aim to investigate to what extent the recent declines in adult mortality in Belarus and Russia are attributable to the anti-alcohol measures introduced in these two countries in the 2000s. Data and Methods We rely on the detailed cause-specific mortality series for the period 1980–2013. Our analysis focuses on the male population, and considers only a limited number of causes of death which we label as being alcohol-related: accidental poisoning by alcohol, liver cirrhosis, ischemic heart diseases, stroke, transportation accidents, and other external causes. For each of these causes we computed age-standardized death rates. The life table decomposition method was used to determine the age groups and the causes of death responsible for changes in life expectancy over time. Conclusion Our results do not lead us to conclude that the schedule of anti-alcohol measures corresponds to the schedule of mortality changes. The continuous reduction in adult male mortality seen in Belarus and Russia cannot be fully explained by the anti-alcohol policies implemented in these countries, although these policies likely contributed to the large mortality reductions observed in Belarus and Russia in 2005–2006 and in Belarus in 2012. Thus, the effects of these policies appear to have been modest. We argue that the anti-alcohol measures implemented in Belarus and Russia simply coincided with fluctuations in alcohol-related mortality which originated in the past. If these trends had not been underway already, these huge mortality

    TiO₂ nanoparticles were prepared with various linear alkyl chains of alcohols under a sol-gel process. The structure characterization and the photocatalytic reduction of hexavalent chromium of the TiO₂ nanoparticles were investigated. The phase transformation temperature, crystal aggregation and surface area of prepared TiO₂ samples were found to be strongly influenced by alcohol used. The phase transformation from anatase to rutile was retarded and the surface area was reduced for TiO₂ prepared with alcohols of longer alkyl chain. TiO₂ nanoparticles prepared with methanol or ethanol exhibited higher photocatalytic reduction activity of hexavalent chromium possibly due to greater and more positively charged surface area.

    Palladium (PdNTs) and gold nanotubes (AuNTs) were synthesized by the galvanic displacement of silver nanowires. PdNTs and AuNTs have wall thicknesses of 6 nm, outer diameters of 60 nm, and lengths of 5-10 and 5-20 μm, respectively. Rotating disk electrode experiments showed that the PdNTs and AuNTs have higher area normalized activities for the oxygen reduction reaction (ORR) than conventional nanoparticle catalysts. The PdNTs produced an ORR area activity that was 3.4, 2.2, and 3.7 times greater than that on carbon-supported palladium nanoparticles (Pd/C), bulk polycrystalline palladium, and carbon-supported platinum nanoparticles (Pt/C), respectively. The AuNTs produced an ORR area activity that was 2.3, 9.0, and 2.0 times greater than that on carbon-supported gold nanoparticles (Au/C), bulk polycrystalline gold, and Pt/C, respectively. The PdNTs also had lower onset potentials than Pd/C and Pt/C for the oxidation of methanol (0.236 V), ethanol (0.215 V), and ethylene glycol (0.251 V). In comparison to Pt/C, the PdNTs and AuNTs further demonstrated improved alcohol tolerance during the ORR.

    The effects of noise, alcohol, and the combination of the two were studied on muscular fatigue in several mouse strains to investigate a possible interaction between the two stresses. Muscular fatigue was measured by latency to submersion during a forced-swimming test. Animals were exposed to acoustic stimuli of fixed frequency and intensity for 2h preceding the test. Ethanol was administered orally from 30 min to 3h 30 min prior to testing. Alcohol doses and sound intensities were subliminal when administered separately. While no significant interaction occurred between alcohol and audible sound, the interaction between alcohol and infrasound was highly significant indicating that their joint effects are more than merely additive. Blood alcohol measurements indicate that these interactive effects are prolonged for more than 2h after elimination of alcohol from the blood. Effects are similar in genetically deaf and hearing mice, implicating involvement of nonauditory pathways.

    Lactobacillus brevis alcohol dehydrogenase (Lb-ADH) catalyzes reduction of prochiral carbonyl compounds to chiral alcohol and meanwhile consumes its cofactor NADH into NAD(+), while the cofactor regeneration can be catalyzed by Candida boidinii formate dehydrogenase (Cb-FDH). This work presents three different Escherichia coli whole-cell biocatalyst systems expressing recombinant ADH/FDH, FDH-LIN1-ADH and FDH-LIN2-ADH, respectively, all of which display very high efficacies of prochiral carbonyl conversion with respect to conversion rates and enantiomeric excess values. ADH/FDH represents co-expression of Lb-ADH and Cb-FDH under different promoters in a single vector. Fusion of Lb-ADH and Cb-FDH by a linker peptide LIN1 (GGGGS)₂ or LIN2 (EAAAK)₂ generates the two bifunctional enzymes FDH-LIN1-ADH and FDH-LIN2-ADH, which enable efficient asymmetric reduction of prochiral ketones in whole-cell biotransformation.

    The hydrogenation of α,β-unsaturated aldehydes to allylic alcohols or saturated aldehydes provides a typical example to study the catalytic effect on structure-sensitive reactions. In this work, supported platinum nanocatalysts over hydrotalcite were synthesized by an alcohol reduction method. The Pt catalyst prepared by the reduction with a polyol (ethylene glycol) outperforms those prepared with ethanol and methanol in the hydrogenation of cinnamaldehyde. The selectivity towards the C=O bond is the highest over the former, although its mean size of Pt particles is the smallest. The hydroxyl groups on hydrotalcite could act as an internally accessible promoter to enhance the selectivity towards the C=O bond. The optimal Pt catalyst showed a high activity with an initial turnover frequency (TOF) of 2.314 s(-1). This work unveils the synergic effect of metal valence and in situ promoter on the chemoselective hydrogenation, which could open up a new direction in designing hydrogenation catalysts.

  10. Integrated energy production and reduction of the environmental impact at alcohol distillery plants.

    In Brazil cane is being been grown at large scale to produce alcohol as an automotive fuel. Alcohol is the sole product, but there is generation of a large quantity of gaseous (CO2), liquid (vinasse) and solid (bagasse) by-products, which currently have very little or even negative value. By using steam turbines fuelled with bagasse combustion, electric power can be generated at a rate of 1 MWh per m3 of produced alcohol. Anaerobic digestion can be applied to vinasse to produce enough biogas for 0.5 MWh per m3 of alcohol, bringing total electric power production from subproducts to 1.5 MWh per m3 of alcohol. These operations are presently implemented at some distilleries at full scale. It has been shown at bench scale that by applying anaerobic digestion also to bagasse and burning the non-biodegradable residual, the power output can be increased to 2.25 MWh per m3 of alcohol, but the economic feasibility of this option depends on the maximum loading rate of the bagasse digester and the energy price. At the current alcohol production level of 13 x 10(6) m3/year, the power generation potential is 2.2 GW, which represents 4% of the power demand in Brazil. The digested waste water contains about 70% of the nutrient demand of the cane fields, which can be recycled. A preliminary economic evaluation shows that productive use of the subproducts of alcohol distilleries is economically feasible if the price is more than US$30 per MWHh, which is the current sales price in Brazil. Another important advantage of the rational use of by-products is that the generation of electric power has the potential to reduce the emission of CO2 to the atmosphere by 0.8-1.2t per m3 of alcohol compared to generation using natural gas.

    The purification and characterization of three enzymes involved in ethanol formation from acetyl-CoA in Thermoanaerobacter ethanolicus 39E (formerly Clostridium thermohydrosulfuricum 39E) is described. The secondary-alcohol dehydrogenase (2 degrees Adh) was determined to be a homotetramer of 40 kDa subunits (SDS/PAGE) with a molecular mass of 160 kDa. The 2 degrees Adh had a lower catalytic efficiency for the oxidation of 1 degree alcohols, including ethanol, than for the oxidation of secondary (2 degrees) alcohols or the reduction of ketones or aldehydes. This enzyme possesses a significant acetyl-CoA reductive thioesterase activity as determined by NADPH oxidation, thiol formation and ethanol production. The primary-alcohol dehydrogenase (1 degree Adh) was determined to be a homotetramer of 41.5 kDa (SDS/PAGE) subunits with a molecular mass of 170 kDa. The 1 degree Adh used both NAD(H) and NADP(H) and displayed higher catalytic efficiencies for NADP(+)-dependent ethanol oxidation and NADH-dependent acetaldehyde (identical to ethanal) reduction than for NADPH-dependent acetaldehyde reduction or NAD(+)-dependent ethanol oxidation. The NAD(H)-linked acetaldehyde dehydrogenase was a homotetramer (360 kDa) of identical subunits (100 kDa) that readily catalysed thioester cleavage and condensation. The 1 degree Adh was expressed at 5-20% of the level of the 2 degrees Adh throughout the growth cycle on glucose. The results suggest that the 2 degrees Adh primarily functions in ethanol production from acetyl-CoA and acetaldehyde, whereas the 1 degree Adh functions in ethanol consumption for nicotinamide-cofactor recycling.

    Administration of neuropeptide Y (NPY) reduces anxiety-like behavior and alcohol intake in alcohol-preferring rats. The present experiment examined whether the effects of NPY on alcohol drinking are modulated by stress exposure during continuous access or following ethanol deprivation. Female P rats underwent 6 weeks of continuous access to 15% v/v ethanol and water prior to intracerebroventricular (ICV) cannula implantation. Deprived rats underwent two cycles of 5 days of ethanol exposure followed by 2 days of ethanol deprivation, while non-deprived rats had uninterrupted access to ethanol. Stressed rats in both ethanol access groups were exposed to restraint stress for 1 hour 4-6 hours after ethanol was removed from the deprived group in both cycles. ICV infusions of 5.0 μg NPY or aCSF were administered 48 hours following the deprivation/stress procedure, after which ethanol was returned. Rats showed increased ethanol intake following ethanol deprivation compared to non-deprived controls. Food and water intake were increased, while ethanol intake was decreased, in rats infused with NPY. Stress did not increase ethanol intake or alter the response to NPY. Although no stress effects were found, the present experiment replicates previous findings regarding the effectiveness of NPY in reducing ethanol consumption. Future studies aimed at determining the extent to which stress may affect relapse to ethanol drinking and response to NPY would benefit from implementing different stress paradigms and varying the pattern of ethanol access.

    Chromite ore processing residue (COPR), the solid waste product from the high-temperature alkaline processing of ferrochromite (FeO·CrO), contains Cr(VI) in soluble and insoluble compounds formed in the roasting process. This research investigated tartaric acid in combination with Mn and isopropyl alcohol (IPOH ) as co-reductants for reagent- and COPR-derived Cr(VI). The reduction of Cr(VI) by tartaric acid alone at pH 5.0 or greater was negligible; however, in the presence of Mn or IPOH, reduction occurred in hours. Isopropyl alcohol enhanced Cr(VI) reduction, probably via formation of a termolecular complex with the alcohol, tartaric acid, and Cr(VI). In aqueous solutions of reagent-derived Cr(VI) at pH 4, 12 mmol L tartaric acid with 1.0 mmol L Mn or 1.0 mmol L Mn and 0.29 mol L (2% v/v) IPOH reduced 1.0 mmol L Cr(VI) in 48 h. The same treatments at pH 5.5 reduced 0.60 and 0.58 mmol L Cr(VI) (60%) in 96 h, respectively. A minimum half-life of 10.2 h was calculated from first-order rate constants obtained from Mn and IPOH-Mn co-reductant treatments with tartaric acid at pH 4. The most COPR-derived Cr(VI) reduced in suspension was by IPOH and Mn at high acidity (pH 5.8), which reduced 0.52 mmol L (52%) of the COPR-derived soluble Cr(VI) at 96 h. The enhanced reduction of soluble Cr(VI) by tartaric acid by the addition of Mn proceeds within a complex formed by an esterification reaction between tartaric acid and Cr(VI) with Mn bound to tartaric acid. The combined treatment of tartaric acid, IPOH, Mn, and a strong acid to lower the pH of COPR-enriched soils would be effective in field applications of this chemistry. By creating a slurry of the field soil with these amendments, mass transfer limitations would be overcome, and Cr(VI) would be reduced to Cr(III) in days.

    Alcohol is a recognized global risk factor for many diseases and injury types and a major contributor to disability and death. While cost-effective interventions do exist, many countries lack a comprehensive national alcohol harm reduction policy. The Arab world includes 22 diverse countries stretching from North Africa to Western Asia having varying dispositions with regards to alcohol sale and consumption. Epidemiological data is scattered and the picture on alcohol consumption remains blurry. This paper presents the findings of an extensive review conducted on all 22 Arab countries, specifically describing: (1) the density and methodology of alcohol-related peer-reviewed publications over the last two decades (1993-2013); (2) the epidemiology of alcohol consumption given all available data; and (3) the current status of policies in the region. Our search revealed a strikingly low number of alcohol-related peer-reviewed published studies - a total of 81 publications across 22 countries and two decades. Most studies are based on clinical or student samples. Where data is available, age of onset is low and drinking is frequent, in the absence of any available or enforced harm reduction policies. We submit that countries in the Arab region can be divided into four categories by alcohol ban and published data. One category includes countries where alcohol is not banned but data is absent, suggesting an ostrich-like response to a controversial behavior, or reflecting a weak research infrastructure and/or policy landscape. Evidence-informed recommendations and future directions for policy and research are discussed and tailored to countries' current stance on alcohol legislation and consumption. Given the particular vulnerability of youth to uptake of alcohol as well as the resulting short and long term consequences, the paper concludes by focusing on the implications of the findings for youth alcohol harm reduction.

  20. Reduction of furfural to furfuryl alcohol by ethanologenic strains of bacteria and its effect on ethanol production from xylose.

    The ethanologenic bacteria Escherichia coli strains KO11 and LYO1, and Klebsiella oxytoca strain P2, were investigated for their ability to metabolize furfural. Using high performance liquid chromatography and 13C-nuclear magnetic resonance spectroscopy, furfural was found to be completely biotransformed into furfuryl alcohol by each of the three strains with tryptone and yeast extract as sole carbon sources. This reduction appears to be constitutive with NAD(P)H acting as electron donor. Glucose was shown to be an effective source of reducing power. Succinate inhibited furfural reduction, indicating that flavins are unlikely participants in this process. Furfural at concentrations >10 mM decreased the rate of ethanol formation but did not affect the final yield. Insight into the biochemical nature of this furfural reduction process may help efforts to mitigate furfural toxicity during ethanol production by ethanologenic bacteria.

    Legislation requires the healthcare industry to directly engage patients through technology. This paper proposes a model that can be used to review hospital websites for features that engage patients in their healthcare. The model describes four levels of patient engagement in website design. The sample consisted of 130 hospital websites from hospitals listed on 2010 and 2011 Most Wired Hospitals. Hospital websites were analyzed for features that encouraged patient interaction with their healthcare according to the levels in the model. Of the four levels identified in the model, websites ranged from "informing" to "collaborative" in website design. There was great variation of features offered on hospital websites with few being engaging and interactive.

    Over recent decades, the average ethanol concentration of wine has increased, largely due to consumer preference for wine styles associated with increased grape maturity; sugar content increases with grape maturity, and this translates into increased alcohol content in wine. However, high ethanol content impacts wine sensory properties, reducing the perceived complexity of flavors and aromas. In addition, for health and economic reasons, the wine sector is actively seeking technologies to facilitate the production of wines with lower ethanol content. Nonconventional yeast species, in particular, non-Saccharomyces yeasts, have shown potential for producing wines with lower alcohol content. These yeast species, which are largely associated with grapes preharvest, are present in the early stages of fermentation but, in general, are not capable of completing alcoholic fermentation. We have evaluated 50 different non-Saccharomyces isolates belonging to 24 different genera for their capacity to produce wine with a lower ethanol concentration when used in sequential inoculation regimes with a Saccharomyces cerevisiae wine strain. A sequential inoculation of Metschnikowia pulcherrima AWRI1149 followed by an S. cerevisiae wine strain was best able to produce wine with an ethanol concentration lower than that achieved with the single-inoculum, wine yeast control. Sequential fermentations utilizing AWRI1149 produced wines with 0.9% (vol/vol) and 1.6% (vol/vol) (corresponding to 7.1 g/liter and 12.6 g/liter, respectively) lower ethanol concentrations in Chardonnay and Shiraz wines, respectively. In Chardonnay wine, the total concentration of esters and higher alcohols was higher for wines generated from sequential inoculations, whereas the total concentration of volatile acids was significantly lower. In sequentially inoculated Shiraz wines, the total concentration of higher alcohols was higher and the total concentration of volatile acids was reduced compared with those in

    Aim To test the possibility of identifying community readiness changes over time. Method Key responders in seven municipalities in Stockholm County were interviewed about the availability of alcohol and parental support. The results were analyzed with paired t tests. Changes in community readiness were assessed. Ninety-three key responders from the participating communities were interviewed three times each, resulting in a total of 315 interviews. Data were collected on three occasions separated by ten months from semistructured telephone interviews based on the community readiness model. Findings Significant readiness changes were found for both issues from baseline to the first follow-up. In terms of the six dimensions of community readiness, significant differences were evident from baseline to the first follow-up for parental support and the reduction of alcohol availability. Apart from knowledge of reduced alcohol availability, there were no significant changes in overall readiness or in the dimensions from the first follow-up to the second. The findings of this study are discussed in relation to earlier studies. Conclusion In communities with an initial vague awareness of issues, a change in readiness level occurs in less than a year.

    The radiolytic reduction of colourless tetrazolium salts to coloured formazans in liquid and solid state is suggested for dosimetry purposes. In order to clarify the reaction mechanism, a pulse radiolysis study was conducted in aqueous and aqueous-alcoholic solutions under oxidative and reductive conditions. Under reducing conditions, fast formation of the electron adduct tetrazolinyl radical was observed: coloured formazan final product formed during the decay of electron adduct. Both the decay of the tetrazolinyl radical and the formation of the formazan were found to be second order. The spectra of the formazan were similar in neutral and alkaline solutions, but with higher absorbance in the latter solutions due to the higher molar absorption coefficient. Under oxidative conditions formazan did not form; hydroxylated products through OH-adducts were observed in the pH range studied.

    We assessed the feasibility of measuring the extracellular reduction of ferricyanide in the presence of an intermediate carrier (menadione) as a means of estimating the activity of yeasts during alcoholic fermentation. A spectrophotometric and a potentiometric approach were used. Comparison of specific reductase activity and gas production rate during the stationary phase indicated that measuring the menadione-catalyzed reduction of ferricyanide provides a good estimate of the total activity of the yeast cells in a fermenting must. The response observed following the addition of an electron acceptor (acetaldehyde) confirmed that the reductase activity of menadione is dependent on the availability of NADH. The stability of menadione in the fermentation medium, as assessed by the potentiometric method, suggested that electrochemical reoxidation of the ferrocyanide can act as a substitute for the addition of an electron acceptor when studying the redox regulation of fermenting yeasts.

    Electrochemical reduction of CO2 in an aqueous 0.5 M KHCO3 solution is studied by use of novel nanostructured Cu-Au alloys, which are prepared through electrochemical deposition with a nanoporous Cu film (NCF) as template. Linear voltammetry results show that the as-synthesized Cu-Au alloys exhibit obvious catalysis towards electrochemical reduction of CO2. Further analysis of products reveals that faradic efficiencies of alcohols (methanol and ethanol) are greatly dependent on the nanostructures and compositions of Cu-Au alloys. It is expected that this work could provide new insight into the development of powerful electrocatalysts for reduction of CO2 to alcohols.

    The reactions of deuterated methanol, ethanol, 1-propanol, 1-butanol, 2-propanol, 2-butanol and t-butanol over cyclic (MO3)3 (M = Mo, W) clusters were studied experimentally with temperature programmed desorption (TPD) and theoretically with coupled cluster CCSD(T) theory and density functional theory. The reactions of two alcohols per M3O9 cluster are required to provide agreement with experiment for D2O release, dehydrogenation and dehydration. The reaction begins with the elimination of water by proton transfers and forms an intermediate dialkoxy species which can undergo further reaction. Dehydration proceeds by a β hydrogen transfer to a terminal M=O. Dehydrogenation takes place via an α hydrogen transfer to an adjacent MoVI = O atom or a WVI metal center with redox involved for M = Mo and no redox for M = W. The two channels have comparable activation energies. H/D exchange to produce alcohols can take place after olefin is released or via the dialkoxy species depending on the alcohol and the cluster. The Lewis acidity of the metal center with WVI being larger than MoVI results in the increased reactivity of W3O9 over Mo3O9 for dehydrogenation and dehydration.

    The objective of the present study was to investigate the changes in gene expression in the fetal brain (forebrain and hippocampus) caused by maternal binge alcohol consumption. Pregnant C57BL/6J mice were treated intragastrically with distilled phosphate-buffered saline (PBS) or ethanol (2.9 g/kg) from embryonic day (ED) 8-12. Microarray analysis revealed that a significant number of genes were altered at ED 18 in the developing brain. Specifically, in hippocampus, nuclear factor one alpha (Nfia) and three N-methyl-D-aspartate (Nmda) receptors (Nmdar1, Nmdar2b, and Nmdar2d) were down-regulated. The transcription factor Nfia controls gliogenesis, cell proliferation and Nmda-induced neuronal survival by regulating the expression of target genes. Some of the Nfia-target gene (Aldh1a, Folh1, Gjb6, Fgf1, Neurod1, Sept4, and Ntsr2) expressions were also altered as expected. These results suggest that the altered expression of Nfia and Nmda receptors may be associated with the etiology of fetal alcohol syndrome (FAS). The data presented in this report will contribute to the understanding of the molecular mechanisms associated with the effects of alcohol in FASD individuals.

    The NASA combustion branch is a leader in developing and applying combustion science to focused aerospace propulsion systems concepts. It is widely recognized for unique facilities, analytical tools, and personnel. In order to better communicate the outstanding research being done in this Branch to the public and other research organization, a more substantial website was desired. The objective of this project was to build an up-to-date site that reflects current research in a usable and attractive manner. In order to accomplish this, information was requested from all researchers in the Combustion branch, on their professional skills and on the current projects. This information was used to fill in the Personnel and Research sections of the website. A digital camera was used to photograph all personnel and these photographs were included in the personnel section as well. The design of the site was implemented using the latest web standards: xhtml and external css stylesheets. This implementation conforms to the guidelines recommended by the w3c. It also helps to ensure that the web site is accessible by disabled users, and complies with Section 508 Federal legislation (which mandates that all Federal websites be accessible). Graphics for the new site were generated using the gimp (www.gimp.org) an open-source graphics program similar to Adobe Photoshop. Also, all graphics on the site were of a reasonable size (less than 20k, most less than 2k) so that the page would load quickly. Technologies such as Macromedia Flash and Javascript were avoided, as these only function on some clients which have the proper software installed or enabled. The website was tested on different platforms with many different browsers to ensure there were no compatibility issues. The website was tested on windows with MS IE 6, MSIE 5 , Netscape 7, Mozilla and Opera. On a Mac, the site was tested with MS IE 5 , Netscape 7 and Safari.

    Production of alcohol-free beer by limited fermentation is optimally performed in a packed-bed reactor. This highly controllable system combines short contact times between yeast and wort with the reduction of off-flavors to concentrations below threshold values. In the present study, the influence of immobilization of yeast to DEAE-cellulose on sugar fermentation and aldehyde reduction was monitored. Immobilized cells showed higher activities of hexokinase and pyruvate decarboxylase compared to cells grown in batch culture. In addition, a higher glucose flux was observed, with enhanced excretion of main fermentation products, indicating a reduction in the flux of sugar used for biomass production. ADH activity was higher in immobilized cells compared to that in suspended cells. However, during prolonged production a decrease was observed in NAD-specific ADH activity, whereas NADP-specific activity increased in the immobilized cells. The shifts in enzyme activities and glucose flux correlate with a higher in vivo reduction capacity of the immobilized cells.

    Samarium iodide-mediated cross-coupling of N-tosyl ferrocenylideneamine with planar chiral ferrocenecarboxaldehydes or benzaldehyde chromium complexes gave diastereoselectively the corresponding anti-beta-amino alcohol derivatives in good yields, while N-tosyl benzylideneamine produced syn-beta-amino alcohols by coupling with planar chiral arylaldehydes. Dynamic kinetic resolution of a configurationally equilibrated reactive species generated from achiral N-tosyl ferrocenilideneamine and benzylideneamine by reduction with samarium iodide was observed in the cross-coupling with planar chiral arylaldehydes giving both antipodes of beta-amino alcohols depending on the planar chirality. The obtained anti-beta-amino alcohol with the ferrocene ring was utilized as a chiral ligand for catalytic asymmetric reduction of acetophenone.

    In the presence of a catalyst system consisting of a ruthenium/triphos complex and the Brønsted acid trifluoromethanesulfonimide, mixtures of fatty acids and aliphatic alcohols are converted into the corresponding ethers at 70 bar H2 . The protocol allows the sustainable one-step synthesis of valuable long-chain ether fragrances, lubricants, and surfactants from renewable sources. The reaction protocol is extended to various fatty acids and esters both in pure form and as mixtures, for example, tall oil acids or rapeseed methyl ester (RME). Even the mixed triglyceride rapeseed oil was converted in one step.

    The ethanol intake of Fawn-Hooded rats, a serotonin deficient strain, was examined under a two bottle choice between ethanol (10%) and tap water. The Fawn-Hooded rats drank as much ethanol as the alcohol preferring strain of rats (approximately 6 times that of the control Wistar rats), but drank more fluid and ate more. In general, direct and indirect serotonin agonists, reduced ethanol intake to a smaller degree in the Fawn-Hooded rats compared to the P rats. In contrast the centrally acting antimuscarinic scopolamine reduced ethanol intake to a similar degree in the two strains.

    Reduction of Cu 2+ ions with and without I - as a ligand was studied in N 2-purged alcoholic solutions by pulse radiolysis. In the absence of iodide ion, the initial rate constant for e -sol reaction with Cu 2+ was determined following the decay of solvated electrons in different alcohols; kbimol values are in the range of 0.8-1.1×10 10 dm 3 mol -1 s -1. In the presence of 10 -3 mol dm -3 KI, the respective kbimol remained almost same. Generally, on reduction, Cu(II) ion changes to Cu(I) ion initially and later it produces metallic copper (Cu°), and the stability of these intermediates depends on the conditions of the matrix. In the presence of I -, Copper ions such as Cu(II) or Cu(I) ions get reduced to metallic copper (Cu°) having initial absorption around 740 and below 400 nm. Later, at 100 μs time after the electron pulse, it gets transformed into a nanoparticle with an absorption band at 580 nm. Such formation of copper nanoparticle was observed only in 2-propanolic medium in the presence of iodide ions. During γ-radiolysis of N 2-purged 1.5×10 -4 CuSO 4 solutions in 2-propanol, reddish pink colored copper nanoparticles were formed, which are quite similar to those reported earlier in aqueous solution. But, in the presence of I - (2-propanolic solutions), such phenomenon was not noticed on γ-radiolysis. Interestingly, the formation of copper nanoparticle was observed also in the reactions of copper (II) ions with alcohol radicals formed during γ-radiolysis in N 2O-purged system, where e -sol were scavenged by N 2O. The nanoparticles generated both in N 2 and N 2O-purged alcoholic systems, viz. methanol, ethanol and 2-propanol, were found to be oxygen sensitive. The contradictory results from pulse and γ-radiolysis studies in the presence and absence of iodide ions are explained to account for the nanoparticle generation.

    2008-09-01

    In this research we demonstrated a new method to produce alcohols. It was experimentally feasible to produce ethanol, propanol and butanol from solely volatile fatty acids (VFAs) with hydrogen as electron donor. In batch tests, VFAs such as acetic, propionic and butyric acids were reduced by mixed microbial cultures with a headspace of 1.5 bar of hydrogen. Observed alcohol concentrations were 3.69+/-0.25 mM of ethanol, 8.08+/-0.85 mM of propanol and 3.66+/-0.05 mM of n-butanol. The conversion efficiency based on the electron balance was 55.1+/-5.6% with acetate as substrate, 50.3+/-4.7% with propionate and 46.7+/-2.2% with n-butyrate. Methane was the most predominant by-product in each batch experiment, 33.6+/-9.6% of VFA and hydrogen was converted to methane with acetate as substrate; which was 27.1+/-7.1% with propionate and 36.6+/-2.2% with n-butyrate. This VFAs reducing renewable fuel production process does not require carbohydrates like fermentable sugars, but uses biomass with high water content or low sugar content that is unsuitable as feedstock for current fermentation processes. This so-called low-grade biomass is abundantly present in many agricultural areas and is economically very attractive feedstock for the production of biofuels.

    Previous studies have suggested that administration of oxytocin (OT) can have modulatory effects on social and anxiety-like behavior in mammals that may endure beyond the time of acute OT administration. The current study examined whether repeated administration of OT to male Wistar rats (n = 48) during a key developmental epoch (early adolescence) altered their physiology and behavior in later-life. Group housed rats were given intraperitoneal injections of either 1 mg/kg OT or vehicle during early adolescence (post natal-days [PND] 33-42). OT treatment caused a transient inhibition of body weight gain that recovered quickly after the cessation of treatment. At PND 50, the rats pre-treated with OT displayed less anxiety-like behavior on the emergence test, while at PND 55 they showed greater levels of social interaction. A subgroup of OT pre-treated rats examined at PND 63 showed a strong trend towards increased plasma OT levels, and also displayed significantly increased OT receptor mRNA in the hypothalamus. Rats pre-treated with OT and their controls showed similar induction of beer intake in daily 70 min test sessions (PND 63 onwards) in which the alcohol concentration of beer was gradually increased across days from 0.44% to 4.44%. However, when given ad libitum access to beer in their home cages from PND 72 onwards (early adulthood), consumption of beer but not water was significantly less in the OT pre-treated rats. A "booster" shot of OT (1 mg/kg) given after 25 days of ad libitum access to beer had a strong acute inhibitory effect on beer intake without affecting water intake. Overall these results suggest that exogenous OT administered during adolescence can have subtle yet enduring effects on anxiety, sociability and the motivation to consume alcohol. Such effects may reflect the inherent neuroplasticity of brain OT systems and a feed-forward effect whereby exogenous OT upregulates endogenous OT systems.

    Fetal alcohol spectrum disorders (FASD) are associated with cognitive and behavioral deficits, and decreased volume of the whole brain and cerebral cortex. Rodent models have shown that early postnatal treatments, which mimic ethanol toxicity in the third trimester of human pregnancy, acutely induce widespread apoptotic neuronal degeneration and permanent behavioral deficits. However, the lasting cellular and anatomical effects of early ethanol treatments are still incompletely understood. This study examined changes in neocortex volume, thickness, and cellular organization that persist in adult mice after postnatal day 7 (P7) ethanol treatment. Post mortem brain volumes, measured by both MRI within the skull and by fluid displacement of isolated brains, were reduced 10-13% by ethanol treatment. The cerebral cortex showed a similar reduction (12%) caused mainly by lower surface area (9%). In spite of these large changes, several features of cortical organization showed little evidence of change, including cortical thickness, overall neuron size, and laminar organization. Estimates of total neuron number showed a trend level reduction of about 8%, due mainly to reduced cortical volume but unchanged neuron density. However, counts of calretinin (CR) and parvalbumin (PV) subtypes of GABAergic neurons showed a striking >30% reduction of neuron number. Similar ethanol effects were found in male and female mice, and in C57BL/6By and BALB/cJ mouse strains. Our findings indicate that the cortex has substantial capacity to develop normal cytoarchitectonic organization after early postnatal ethanol toxicity, but there is a selective and persistent reduction of GABA cells that may contribute to the lasting cognitive and behavioral deficits in FASD.

    Fetal alcohol spectrum disorders (FASD) are associated with cognitive and behavioral deficits, and decreased volume of the whole brain and cerebral cortex. Rodent models have shown that early postnatal treatments, which mimic ethanol toxicity in the third trimester of human pregnancy, acutely induce widespread apoptotic neuronal degeneration and permanent behavioral deficits. However, the lasting cellular and anatomical effects of early ethanol treatments are still incompletely understood. This study examined changes in neocortex volume, thickness, and cellular organization that persist in adult mice after postnatal day 7 (P7) ethanol treatment. Post mortem brain volumes, measured by both MRI within the skull and by fluid displacement of isolated brains, were reduced 10–13% by ethanol treatment. The cerebral cortex showed a similar reduction (12%) caused mainly by lower surface area (9%). In spite of these large changes, several features of cortical organization showed little evidence of change, including cortical thickness, overall neuron size, and laminar organization. Estimates of total neuron number showed a trend level reduction of about 8%, due mainly to reduced cortical volume but unchanged neuron density. However, counts of calretinin (CR) and parvalbumin (PV) subtypes of GABAergic neurons showed a striking >30% reduction of neuron number. Similar ethanol effects were found in male and female mice, and in C57BL/6By and BALB/cJ mouse strains. Our findings indicate that the cortex has substantial capacity to develop normal cytoarchitectonic organization after early postnatal ethanol toxicity, but there is a selective and persistent reduction of GABA cells that may contribute to the lasting cognitive and behavioral deficits in FASD.

    Lysosomal Acid Lipase (LAL) is a key enzyme involved in lipid metabolism, responsible for hydrolysing the cholesteryl esters and triglycerides. Wolman Disease represents the early onset phenotype of LAL deficiency rapidly leading to death. Cholesterol Ester Storage Disease is a late onset phenotype that occurs with fatty liver, elevated aminotransferase levels, hepatomegaly and dyslipidaemia, the latter characterized by elevated LDL-C and low HDL-C. The natural history and the clinical manifestations of the LAL deficiency in adults are not well defined, and the diagnosis is often incidental. LAL deficiency has been suggested as an under-recognized cause of dyslipidaemia and fatty liver. Therefore, LAL activity may be reduced also in non-obese patients presenting non-alcoholic fatty liver disease (NAFLD), unexplained persistently elevated liver transaminases or with elevation in LDL cholesterol. In these patients, it could be indicated to test LAL activity. So far, very few studies have been performed to assess LAL activity in representative samples of normal subjects or patients with NAFLD. Moreover, no large study has been carried out in adult subjects with NAFLD or cryptogenic cirrhosis. PMID:26602919

    Hand washing is the most effective way to prevent the spread of communicable disease. The purpose of this double-blind, placebo-controlled study was to assess whether an alcohol-free, instant hand sanitizer containing surfactants, allantoin, and benzalkonium chloride could reduce illness absenteeism in a population of 769 elementary school children and serve as an effective alternative when regular soap and water hand washing was not readily available. Prior to the study, students were educated about proper hand washing technique, the importance of hand washing to prevent transmission of germs, and the relationship between germs and illnesses. Children in kindergarten through the 6th grade (ages 5-12) were assigned to the active or placebo hand-sanitizer product and instructed to use the product at scheduled times during the day and as needed after coughing or sneezing. Data on illness absenteeism were tracked. After 5 weeks, students using the active product were 33% less likely to have been absent because of illness when compared with the placebo group.

    The Trajectory Browser is a web-based tool developed at the NASA Ames Research Center to be used for the preliminary assessment of trajectories to small-bodies and planets and for providing relevant launch date, time-of-flight and V requirements. The site hosts a database of transfer trajectories from Earth to asteroids and planets for various types of missions such as rendezvous, sample return or flybys. A search engine allows the user to find trajectories meeting desired constraints on the launch window, mission duration and delta V capability, while a trajectory viewer tool allows the visualization of the heliocentric trajectory and the detailed mission itinerary. The anticipated user base of this tool consists primarily of scientists and engineers designing interplanetary missions in the context of pre-phase A studies, particularly for performing accessibility surveys to large populations of small-bodies. The educational potential of the website is also recognized for academia and the public with regards to trajectory design, a field that has generally been poorly understood by the public. The website is currently hosted on NASA-internal URL http://trajbrowser.arc.nasa.gov/ with plans for a public release as soon as development is complete.

    In an attempt to understand the nature of selectivity in Ti-mediated reductive cross-coupling between homoallylic alcohols and imines, we investigated whether thermodynamic equilibration of the presumed organometallic intermediate plays a role in selectivity. No evidence could be found for olefin exchange in preformed azatitanacyclopentanes--an observation that is consistent with a model based on kinetically controlled selective carbometalation.

    A randomized control trial was conducted at a midsized private university in the Northeast to evaluate the short-term impact of AlcoholEdu for College 8.0, an online alcohol course for first-year students. In September 2007, 1,620 matriculated first-year students were randomly assigned to either a treatment group or an assessment-only control group. Both groups of students completed a baseline survey and knowledge test. Treatment group students finished the course, took a second knowledge test, and 30 days later completed a postintervention survey. Control group students completed the postintervention survey and knowledge test during the same time period. Compared with the control group, treatment group students reported a significantly lower level of alcohol use, fewer negative drinking consequences, and less positive alcohol-related attitudes. AlcoholEdu 8.0 had a positive impact on the first-year students' alcohol-related attitudes, behaviors, and consequences. Additional investigations of online alcohol education courses are warranted.

    Neuropathy and neurocognitive deficits are common among chronic alcohol users, which are believed to be associated with mitochondrial dysfunction in the brain. The specific type of brain mitochondrial respiratory chain complexes (mRCC) that are adversely affected by alcohol abuse has not been studied. Thus, we examined the alterations of mRCC in freshly isolated mitochondria from mice brain that were pair-fed the ethanol (4% v/v) and control liquid diets for 7–8 weeks. We observed that alcohol intake severely reduced the levels of complex I and V. A reduction in complex I was associated with a decrease in carnitine palmitoyltransferase 1 (cPT1) and cPT2 levels. The mitochondrial outer (cPT1) and inner (cPT2) membrane transporter enzymes are specialized in acylation of fatty acid from outer to inner membrane of mitochondria for ATP production. Thus, our results showed that alterations of cPT1 and cPT2 paralleled a decrease β-oxidation of palmitate and ATP production, suggesting that impairment of substrate entry step (complex I function) can cause a negative impact on ATP production (complex V function). Disruption of cPT1/cPT2 was accompanied by an increase in cytochrome C leakage, while reduction of complex I and V paralleled a decrease in depolarization of mitochondrial membrane potential (ΔΨ, monitored by JC-1 fluorescence) and ATP production in alcohol intake. We noted that acetyl-L-carnitine (ALC, a cofactor of cPT1 and cPT2) prevented the adverse effects of alcohol while coenzyme Q10 (CoQ10) was not very effective against alcohol insults. These results suggest that understanding the molecular, biochemical, and signaling mechanisms of the CNS mitochondrial β-oxidation such as ALC can mitigate alcohol related neurological disorders.

  18. Improved conversion efficiencies for n-fatty acid reduction to primary alcohols by the solventogenic acetogen "Clostridium ragsdalei".

    PubMed

    Isom, Catherine E; Nanny, Mark A; Tanner, Ralph S

    2015-01-01

    "Clostridium ragsdalei" is an acetogen that ferments synthesis gas (syngas, predominantly H2:CO2:CO) to ethanol, acetate, and cell mass. Previous research showed that C. ragsdalei could also convert propionic acid to 1-propanol and butyric acid to 1-butanol at conversion efficiencies of 72.3 and 21.0 percent, respectively. Our research showed that C. ragsdalei can also reduce pentanoic and hexanoic acid to the corresponding primary alcohols. This reduction occurred independently of growth in an optimized medium with headspace gas exchange (vented and gassed with CO) every 48 h. Under these conditions, conversion efficiencies increased to 97 and 100 % for propionic and butyric acid, respectively. The conversion efficiencies for pentanoic and hexanoic acid to 1-pentanol and 1-hexanol, respectively, were 82 and 62 %. C. ragsdalei also reduced acetone to 2-propanol at a conversion efficiency of 100 %. Further, we showed that C. ragsdalei uses an aldehyde oxidoreductase-like enzyme to reduce n-fatty acids to the aldehyde intermediates in a reaction that requires ferredoxin and exogenous CO.

    2016-01-01

    Background Alcohol is known to affect two epigenetic phenomena, DNA methylation and DNA hydroxymethylation, and iron is a cofactor of ten-eleven translocation (TET) enzymes that catalyze the conversion from methylcytosine to hydroxymethylcytosine. In the present study we aimed to determine the effects of alcohol on DNA hydroxymethylation and further effects of iron on alcohol associated epigenetic changes. Methods Twenty-four male Sprague-Dawley rats were fed either Lieber-DeCarli alcohol diet (36% calories from ethanol) or Lieber-DeCarli control diet along with or without iron supplementation (0.6% carbonyl iron) for 8 weeks. Hepatic non-heme iron concentrations were measured by colorimetric assays. Protein levels of hepatic ferritin and transferrin receptor were determined by Western blotting. Methylcytosine, hydroxymethylcytosine and unmodified cytosine in DNA were simultaneously measured by liquid chromatography/mass spectrometry method. Results Iron supplementation significantly increased hepatic non-heme iron contents (P < 0.05) but alcohol alone did not. However, both alcohol and iron significantly increased hepatic ferritin levels and decreased hepatic transferrin receptor levels (P < 0.05). Alcohol reduced hepatic DNA hydroxymethylation (0.21% ± 0.04% vs. 0.33% ± 0.04%, P = 0.01) compared to control, while iron supplementation to alcohol diet did not change DNA hydroxymethylation. There was no significant difference in methylcytosine levels, while unmodified cytosine levels were significantly increased in alcohol-fed groups compared to control (95.61% ± 0.08% vs. 95.26% ± 0.12%, P = 0.03), suggesting that alcohol further increases the conversion from hydroxymethylcytosine to unmodified cytosine. Conclusions Chronic alcohol consumption alters global DNA hydroxymethylation in the liver but iron supplementation reverses the epigenetic effect of alcohol. PMID:28053961

    Objectives: Reduced vitamin E levels have been reported in patients with non-alcoholic steatohepatitis (NASH), but no conclusive data on patients with simple steatosis (SS) are available. Aim of this study was to investigate the association between serum vitamin E levels and SS. Methods: A cohort of 312 patients with cardio-metabolic risk factors was screened for liver steatosis by ultrasonography (US). We reasonably classified as SS patients with US-fatty liver, normal liver function tests (LFTs) and with Cytokeratin 18 <246 mIU/ml. Liver biopsy was performed in 41 patients with US-fatty liver and persistent elevation of LFTs (>6 months). Serum cholesterol-adjusted vitamin E (Vit E/chol) levels were measured. Results: Mean age was 53.9±12.5 years and 38.4% were women. Non-alcoholic fatty liver disease (NAFLD) was detected at US in 244 patients; of those 39 had biopsy-proven NASH and 2 borderline NASH. Vit E/chol was reduced in both SS (3.4±2.0, P<0.001), and NASH (3.5±2.1, P=0.006) compared with non-NAFLD patients (4.8±2.0 μmol/mmol chol). No difference was found between SS and NASH (P=0.785). After excluding patients with NASH, a multivariable logistic regression analysis found that Vit E/chol (odds ratio (OR): 0.716, 95% confidence interval (CI) 0.602–0.851, P<0.001), alanine aminotransferase (ALT, OR: 1.093, 95% CI 1.029–1.161, P=0.004), body mass index (OR: 1.162, 95% CI 1.055–1.279, P=0.002) and metabolic syndrome (OR: 5.725, 95% CI 2.247–14.591, P<0.001) were factors independently associated with the presence of SS. Conclusions: Reduced vitamin E serum levels are associated with SS, with a similar reduction between patients with SS and NASH, compared with non-NAFLD patients. Our findings suggest that the potential benefit of vitamin E supplementation should be investigated also in patients with SS. PMID:26426796

    2011-12-01

    Alcohol use and firearm ownership are risk factors for violent injury and death. To determine whether firearm ownership and specific firearm-related behaviours are associated with alcohol-related risk behaviours, the author conducted a cross-sectional study using Behavioral Risk Factor Surveillance System data for eight states in the USA from 1996 to 1997 (the most recent data available). Altogether, 15 474 respondents provided information on firearm exposure. After adjustment for demographics and state of residence, firearm owners were more likely than those with no firearms at home to have ≥5 drinks on one occasion (OR 1.32; 95% CI 1.16 to 1.50), to drink and drive (OR 1.79; 95% CI 1.34 to 2.39) and to have ≥60 drinks per month (OR 1.45; 95% CI 1.14 to 1.83). Heavy alcohol use was most common among firearm owners who also engaged in behaviours such as carrying a firearm for protection against other people and keeping a firearm at home that was both loaded and not locked away. The author concludes that firearm ownership and specific firearm-related behaviours are associated with alcohol-related risk behaviours.

With simulations of the model, we can explain most of the important characteristics of websites. These characteristics include a power-law distribution of the number of visitors to websites, fluctuation in the fractional growth of individual websites, and the relationship between the age and the popularity of the websites. We also investigated a few variants of the model and showed that the ingredients included in the model adequately explain the behavior of the websites.

    Aims To evaluate whether an alcohol harm reduction intervention was associated with reduced interpersonal violence or engagement in sex work among female sex workers (FSWs) in Mombasa, Kenya. Design Randomized controlled trial. Setting HIV prevention drop-in centers in Mombasa, Kenya. Participants 818 women 18 or older in Mombasa who visited HIV prevention drop-in centers, were moderate-risk drinkers and engaged in transactional sex in past six months (410 and 408 in intervention and control arms, respectively). Intervention 6 session alcohol harm reduction intervention. Comparator 6 session non-alcohol related nutrition intervention. Measurements In-person interviews were conducted at enrollment, immediately post-intervention and 6-months post-intervention. General linear mixed models examined associations between intervention assignment and recent violence (physical violence, verbal abuse, and being robbed in the past 30 days) from paying and non-paying sex partners and engagement in sex work in the past 30 days. Findings The alcohol intervention was associated with statistically significant decreases in physical violence from paying partners at 6 months post-intervention and verbal abuse from paying partners immediately post-intervention and 6-months post-intervention. Those assigned to the alcohol intervention had significantly reduced odds of engaging in sex work immediately post-intervention and 6-months post-intervention. Conclusions The alcohol intervention was associated with reductions in some forms of violence and with reductions in engagement in sex work among FSWs in Mombasa, Kenya. PMID:26872880

    Laboratory methodology websites are specialized niche websites. The visibility of a niche website transforms it into an authority site on a particular “niche of knowledge.” This article presents some ways in which a laboratory methodology website can maintain its sustainability. The optimal composition of the website includes a basic content, a blog, and an ancillary part. This article discusses experimenting with the search engine optimization query results page.

    The opiate antagonist naltrexone (Ntx) has demonstrated efficacy in the treatment of alcohol dependence and as a component of treatment to reduce heavy drinking. At present, there are no published dose-ranging clinical trials of the oral preparation for treatment of problem drinking. The present study evaluated the effects of Ntx on alcohol use among the subset of hazardous drinkers (n=102) who participated in a placebo-controlled, dose-ranging trial of oral Ntx (25-mg, 50-mg and 100-mg doses) combined with open-label transdermal nicotine patch for enhancing smoking cessation. On the primary outcome--no hazardous drinking (drinking that exceeded weekly or daily limits) during treatment--25 mg and 50 mg Ntx were superior to placebo (each p<0.05). These findings remained after controlling for baseline predictors or smoking abstinence during treatment. Time to remission of hazardous drinking was examined as a secondary outcome with definitions of hazardous drinking based on weekly limits, daily limits and the combination of weekly and daily limits and the results were consistent with the primary findings. In conclusion, the findings suggest that Ntx can reduce the risk of hazardous drinking in smokers who are not seeking or receiving alcohol treatment, providing strong evidence for the pharmacological effects of Ntx on drinking. This effect appears to favour lower doses that may be better tolerated and less expensive than the higher 100-mg dose. Given its efficacy and favourable side-effect profile, the 25-mg dose should be considered for future studies of combination therapy.

    Alcohol/water mixtures, such as those produced by fermentation of biomass material, are separated by extraction of alcohol with a solvent, comprising a higher aliphatic alcohol in major amount and an aliphatic hydrocarbon in minor amount, especially suited to such extraction and to subsequent removal. The solvent alcohol desirably has a branched chain, or the hydrocarbon an unsaturated bond, or both. Conventional distillation steps to concentrate alcohol and eliminate water are rendered unnecessary at a considerable reduction in heat energy requirement (usually met with fossil fuel). Optional addition of gasoline between the solvent extraction and solvent recovery steps not only aids the latter separation but produces alcohol already denatured for fuel use.

    Certain attributes are particularly desirable for public educational websites, and websites for ethics education in particular. Among the most important of these attributes is wide accessibility through adherence to the World Wide Web Consortium (W3C) standards for HTML code. Adherence to this standard produces webpages that can be rendered by a full range of web browsers, including Braille and speech browsers. Although almost no academic websites, including ethics websites, and even fewer commercial websites are accessible by W3C standards, as illustrated by the Online Ethics Center for Engineering and Science , even websites created on limited budgets and with an undergraduate student staff can fulfill these standards. Other desirable attributes, such as provision of annotation for all links and the use of annotated links to give the user alternate ways of ordering and organizing content, are important for making full use of the educational possibilities of hypermedia for websites.

    The novel reductive graphene oxide-based magnetic molecularly imprinted poly(ethylene-co-vinyl alcohol) polymers (rGO@m-MIPs) were successfully synthesized as adsorbents for six kinds of polychlorinated biphenyls (PCBs) in fish samples. rGO@m-MIPs was prepared by surface molecular imprinting technique. Besides, Fe3 O4 nanoparticles (NPs) were employed as magnetic supporters, and rGO@Fe3 O4 was in situ synthesis. Different from functional monomer and cross-linker in traditional molecularly imprinted polymer, here, 3,4-dichlorobenzidine was employed as dummy molecular and poly(ethylene-co-vinyl alcohol) was adopted as the imprinted polymers. After morphology and inner structure of the magnetic adsorbent were characterized, the adsorbent was employed for disperse solid phase extraction toward PCBs and exhibited great selectivity and high adsorption efficiency. This material was verified by determination of PCBs in fish samples combined with gas chromatography-mass spectrometry (GC-MS) method. According to the detection, the low detection limits (LODs) of PCBs were 0.0035-0.0070 µg l(-1) and spiked recoveries ranged between 79.90 and 94.23%. The prepared adsorbent can be renewable for at least 16 times and expected to be a new material for the enrichment and determination of PCBs from contaminated fish samples.

    Couple-based treatments for alcohol use disorders (AUDs) produce higher rates of abstinence than individual-based treatments and posit that active involvement of both identified patients (IPs) and significant others (SOs) is partly responsible for these improvements. Separate research on couples' communication has suggested that pronoun usage can indicate a communal approach to coping with health-related problems. The present study tested whether communal coping, indicated by use of more first-person plural pronouns ("we" language), fewer second-person pronouns ("you" language), and fewer first-person singular pronouns ("I" language), predicted improvements in abstinence in couple-based AUD treatment. Pronoun use was measured in first- and mid-treatment sessions for 188 heterosexual couples in four clinical trials of alcohol behavioral couple therapy (ABCT). Percentages of days abstinent were assessed during treatment and over a 6-month follow-up period. Greater IP and SO "we" language during both sessions was correlated with greater improvement in abstinent days during treatment. Greater SO "we" language during first- and mid-treatment sessions was correlated with greater improvement in abstinence at follow-up. Greater use of IP and SO "you" and "I" language had mixed correlations with abstinence, typically being unrelated to or predicting less improvement in abstinence. When all pronoun variables were entered into regression models, only greater IP "we" langue and lower IP "you" language predicted improvements in abstinence during treatment, and only SO "we" language predicted improvements during follow-up. Most pronoun categories had little or no association with baseline relationship distress. Results suggest that communal coping predicts better abstinence outcomes in couple-based AUD treatment.

    Silver nanoparticle immobilized mesoporous cross-linked polyacrylic acid (Ag-MCP-1) has been synthesized via aqueous-phase polymerization of acrylic acid followed by the surface immobilization with silver nanoparticles. The nanocomposite material has been characterized by different spectroscopic techniques. Powder X-ray diffraction patterns revealed the formation of silver nanoparticles, while transmission electron microscope image showed that Ag nanoparticles are formed and uniformly dispersed in the mesoporous polyacrylic acid. The Ag-MCP-1 nanocomposite can be used as an efficient heterogeneous catalyst in the reductive coupling of nitrobenzenes and alcohols using glycerol as hydrogen source. This nanocomposite can be reused more than five times without any significant decrease in its catalytic activity.

    Background Ex-drinkers suffer from worse health than drinkers; however, whether a worsening of health is associated with a change in drinking status from early adulthood has not been previously investigated. We assess whether a worsening of health is associated with a cessation in consumption or reduction to special occasion drinking from early adulthood to middle age. Methods Multinomial logistic regression assessing whether a change in self-reported limiting longstanding illness (LLI) was associated with ceasing alcohol consumption, or a reduction to special occasion drinking compared with being a persistent drinker from age 23 in separate models at ages 33, 42, and 50. All models adjusted for sex, poor psychosocial health, education, marital status, and children in the household. Sample included participants from Great Britain followed longitudinally in the National Child Development Study from ages 23 to 33 (N = 5,529), 42 (N = 4,787), and 50 (N = 4,476). Results Developing an LLI from the previous wave was associated with ceasing alcohol consumption at ages 33 (odds ratio [ORs] = 2.71, 95% confidence interval [CI] = 1.16–4.93), 42 (OR = 2.44, 95%CI = 1.24–4.81), and 50 (OR = 3.33, 95%CI = 1.56–7.12) and a reduction to special occasion drinking at ages 42 (OR = 2.04, 95%CI = 1.40–2.99) and 50 (OR = 2.04, 95%CI = 1.18–3.53). Having a persistent LLI across 2 waves increased the odds of ceasing consumption at ages 42 (OR = 3.22, 95%CI = 1.06–9.77) and 50 (OR = 4.03, 95%CI = 1.72–9.44) and reducing consumption to special occasion drinking at ages 33 (OR = 3.27, 95%CI = 1.34–8.01) and 42 (OR = 2.25, 95%CI = 1.23–4.50). Persistent drinkers at older ages had the best overall health suffering less from previous poor health compared with those who reduced or ceased consumption at an earlier time point.

    This study investigates the effects of alcohol advertising on adolescent alcohol consumption. The theory of an industry response function and evidence from prior studies indicate the importance of maximizing the variance in advertising measures. Monitoring the Future (MTF) and National Longitudinal Survey of Youth 1997 (NLSY97) data are augmented with alcohol advertising, originating on the market level, for five media. The large sample of the MTF allows estimation of race and gender-specific models. The longitudinal nature of the NLSY97 allows controls for unobserved heterogeneity with state-level and individual fixed effects. Price and advertising effects are generally larger for females relative to males. Controls for individual heterogeneity yield larger advertising effects, implying that the MTF results may understate the effects of alcohol advertising. Results from the NLSY97 suggest that a 28% reduction in alcohol advertising would reduce adolescent monthly alcohol participation from 25% to between 24 and 21%. For binge participation, the reduction would be from 12% to between 11 and 8%. The past month price-participation elasticity is estimated at -0.26, consistent with prior studies. The results show that reduction of alcohol advertising can produce a modest decline in adolescent alcohol consumption, though effects may vary by race and gender.

    Introduction Non-alcoholic fatty liver disease (NAFLD) affects a large part of the human population. One of the major environmental factors associated with the risk of NAFLD is the lack of physical activity. Aim To compare the level of physical activity and the insulin resistance in NAFLD patients. Material and methods Thirty patients with NAFLD underwent a six-month dietary intervention based on the principles of classical dietetics. Data about diet and physical activity was based on 72-hour nutrition diaries and International Physical Activity Questionnaire (IPAQ). Standard blood biochemical analyses were carried out before and after diet at the University Hospital Laboratory. Results The study showed that total physical activity and physical activity in leisure time are negatively correlated with insulin resistance (HOMA-IR) (p < 0.05). Insulin (p < 0.05), body weight (p < 0.05), and waist-hip ratio (WHR) (p < 0.05) were also negatively correlated with physical activity in free time. In addition, we noticed a positive correlation between sitting time and the risk of insulin resistance, in the case of HOMA-IR and insulin concentration (p < 0.05). Conclusions Dietary intervention and a physical activity plan are important factors in the treatment of non-alcoholic fatty liver disease. Taking regular exercise increases insulin sensitivity and prevents further development of the disease. It seems that diet and physical activity are not the only one risk factors of NAFLD. Our study reveals that the reduction of sitting time has a positive effect on the level of insulin and it reduces insulin resistance in patients with NAFLD. PMID:28053680

    This study investigates the treatment of the distilleries vinasse using a hybrid process integrating ozone oxidation and granular activated carbons (GAC) in both batch and continuous operation mode. The batch-process studies have been carried out to optimize initial influent pH, GAC doses, the effect of the ozone (O3) and hydrogen peroxide (H2O2) concentrations on chemical oxygen demand (COD) and color removal of the distilleries vinasse. The continuous process was carried out on GAC and ozone treatment alone as well as the hybrid process comb both methods to investigate the synergism effectiveness of the two methods for distilleries vinasse COD reduction and color removal. In a continuous process, the Yan model described the experimental data better than the Thomas model. The efficiency of ozonation of the distilleries vinasse was more effective for color removal (74.4%) than COD removal (25%). O3/H2O2 process was not considerably more effective on COD and color removal. Moreover, O3/GAC process affected negatively on the removal efficiency by reducing COD and color from distilleries vinasse. The negative effect decreased by increasing pH value of the influent.

    This study deals with the impact of virtual reality (VR) features that are embedded in a hotel website on travelers' anxiety. Having more information is thought to be a factor in relieving anxiety in travel. A hotel website can be a good place for gathering information about the accommodation. In this study, we posit that a hotel website with VR functions should lead to a reduction in travelers' anxiety about travel. We built a website of a hotel and used VR functions to show the exterior, the lobby, a guest room, and a restaurant through an interactive and spatial shot of the hotel images. The experiment was conducted with a premise that the subjects were about to embark on a journey to an unknown place and to stay at an unknown hotel whose website contained VR functions. The subjects were asked to play with VR functions of the hotel website and then to complete a survey with questions regarding the degree of anxiety on the travel and psychological relief that might have been perceived by the subjects. The result confirms our hypothesis that there is a statistically significant relationship between the degree of travel anxiety and psychological relief caused by the use of VR functions of a hotel website.

    Non-alcoholic fatty liver disease (NAFLD) is associated with multi-organ (hepatic, skeletal muscle, adipose tissue) insulin resistance (IR). Exercise is an effective treatment for lowering liver fat but its effect on IR in NAFLD is unknown. We aimed to determine whether supervised exercise in NAFLD would reduce liver fat and improve hepatic and peripheral (skeletal muscle and adipose tissue) insulin sensitivity. Sixty nine NAFLD patients were randomized to 16 weeks exercise supervision (n=38) or counselling (n=31) without dietary modification. All participants underwent MRI/spectroscopy to assess changes in body fat and in liver and skeletal muscle triglyceride, before and following exercise/counselling. To quantify changes in hepatic and peripheral insulin sensitivity, a pre-determined subset (n=12 per group) underwent a two-stage hyperinsulinaemic euglycaemic clamp pre- and post-intervention. Results are shown as mean [95% confidence interval (CI)]. Fifty participants (30 exercise, 20 counselling), 51 years (IQR 40, 56), body mass index (BMI) 31 kg/m(2) (IQR 29, 35) with baseline liver fat/water % of 18.8% (IQR 10.7, 34.6) completed the study (12/12 exercise and 7/12 counselling completed the clamp studies). Supervised exercise mediated a greater reduction in liver fat/water percentage than counselling [Δ mean change 4.7% (0.01, 9.4); P<0.05], which correlated with the change in cardiorespiratory fitness (r=-0.34, P=0.0173). With exercise, peripheral insulin sensitivity significantly increased (following high-dose insulin) despite no significant change in hepatic glucose production (HGP; following low-dose insulin); no changes were observed in the control group. Although supervised exercise effectively reduced liver fat, improving peripheral IR in NAFLD, the reduction in liver fat was insufficient to improve hepatic IR.

  3. Effect of iron(III) sulphate on radiation-induced reduction of methyl viologen incorporated in poly(vinyl alcohol) film

    Addition of iron(III) sulfate (Fe 2(SO 4) 3) to the methyl viologen (MV 2+)-poly(vinyl alcohol) (PVA) film dosimeter led to the induction dose ( Di) before appearance of blue-colored cation radical (MV +.) and reduction of G-value of MV +.. As a result, the measurable range for ionizing radiation (200 kV electron beam) was expanded to the higher dose >400 kGy, which was >25 times larger than that of base MV 2+-PVA film (<14 kGy). In the MV 2+-Fe 2(SO 4) 3-PVA film, iron(II) ion (Fe 2+) was also accumulated without any induction dose. The Fe 2+ still increased after Di, with the G-value relatively smaller than that before Di. Increase in pH ((pH) i) of the source aqueous PVA solution, subjected to casting into films, led to the decrease in Di and increase in G-value of MV +. ( G(MV +.)). The ratio of initial concentration of Fe 3+ (( CFe) i) to Di was apparently independent of ( CFe) i at given (pH) i. These results suggest the mechanism that radiation-induced electrons in the PVA matrix reduce both MV 2+ and Fe 3+, and the resulting MV +. successively reacts with neighboring Fe 3+ to regenerate MV 2+ in the initial stage of irradiation (within Di). At the dose of Di, such neighboring Fe 3+ is consumed entirely and substantial formation of MV +. can be observed.

    Yayac, Michael; Javandal, Mitra; Mulcahey, Mary K.

    2017-01-01

    Background: A substantial number of orthopaedic surgeons apply for sports medicine fellowships after residency completion. The Internet is one of the most important resources applicants use to obtain information about fellowship programs, with the program website serving as one of the most influential sources. The American Orthopaedic Society for Sports Medicine (AOSSM), San Francisco Match (SFM), and Arthroscopy Association of North America (AANA) maintain databases of orthopaedic sports medicine fellowship programs. A 2013 study evaluated the content and accessibility of the websites for accredited orthopaedic sports medicine fellowships. Purpose: To reassess these websites based on the same parameters and compare the results with those of the study published in 2013 to determine whether any improvement has been made in fellowship website content or accessibility. Study Design: Cross-sectional study. Methods: We reviewed all existing websites for the 95 accredited orthopaedic sports medicine fellowships included in the AOSSM, SFM, and AANA databases. Accessibility of the websites was determined by performing a Google search for each program. A total of 89 sports fellowship websites were evaluated for overall content. Websites for the remaining 6 programs could not be identified, so they were not included in content assessment. Results: Of the 95 accredited sports medicine fellowships, 49 (52%) provided links in the AOSSM database, 89 (94%) in the SFM database, and 24 (25%) in the AANA database. Of the 89 websites, 89 (100%) provided a description of the program, 62 (70%) provided selection process information, and 40 (45%) provided a link to the SFM website. Two searches through Google were able to identify links to 88% and 92% of all accredited programs. Conclusion: The majority of accredited orthopaedic sports medicine fellowship programs fail to utilize the Internet to its full potential as a resource to provide applicants with detailed information about the

    Tafuri, Silvio; Gallone, Maria S; Gallone, Maria F; Zorico, Ivan; Aiello, Valeria; Germinario, Cinzia

    2014-01-01

    Babies’ parents and people who look for information about vaccination often visit anti-vaccine movement’s websites, blogs by naturopathic physicians or natural and alternative medicine practitioners. The aim of this work is to provide a quantitative analysis on the type of information available to Italian people regarding vaccination and a quality analysis of websites retrieved through our searches. A quality score was created to evaluate the technical level of websites. A research was performed through Yahoo, Google, and MSN using the keywords “vaccine” and “vaccination,” with the function “OR” in order to identify the most frequently used websites. The 2 keywords were input in Italian, and the first 15 pages retrieved by each search engine were analyzed. 149 websites were selected through this methodology. Fifty-three per cent of the websites belonged to associations, groups, or scientific companies, 32.2% (n = 48) consisted of a personal blog and 14.8% (n = 22) belonged to some of the National Health System offices. Among all analyzed websites, 15.4% (n = 23) came from anti-vaccine movement groups. 37.6% reported webmaster name, 67.8% webmaster e-mail, 28.6% indicated the date of the last update and 46.6% the author’s name. The quality score for government sites was higher on average than anti-vaccine websites; although, government sites don’t use Web 2.0 functions, as the forums. National Health System institutions who have to promote vaccination cannot avoid investing in web communication because it cannot be managed by private efforts but must be the result of Public Health, private and scientific association, and social movement synergy.

  13. Development of the Nutrition4Kids website.

    PubMed

    Williams, Michelle S

    2012-01-01

    According to the 2009 National Vital Statistics Report, cancer is the second-leading cause of death in the United States. Researchers have determined that consuming a diet low in fruits, vegetables, and whole grains is a common risk factor associated with the risk of developing several types of cancer including stomach, colorectal, breast, and pancreatic. Currently, there are few websites devoted to increasing students' knowledge about the role of a healthy diet in cancer prevention. The Nutrition4Kids website is a unique health education tool that targets youth aged 10 to 14 years. The website content and design were based on the Health Belief Model, the Information-Motivation and Behavioral Skills Model, and the principles of health literacy. The information included on the website was based on recommendations from the American Institute for Cancer Research and the World Cancer Research Fund. The website contains nutrition information, recipes that emphasize the consumption of fruits, vegetables, and whole grains, and interactive games. The primary objectives of the Nutrition4Kids website are to 1) increase students' knowledge of how poor dietary habits can affect their health, 2) increase students' knowledge of healthy dietary habits that can reduce their risk for cancer, 3) increase students' ability to prepare healthy, well-balanced meals and snacks, 4) increase students' ability to discuss healthy eating with their family and friends, and 5) increase students' knowledge of nutrients that have healthful benefits.

  14. Dental practice websites: creating a Web presence.

    PubMed

    Miller, Syrene A; Forrest, Jane L

    2002-07-01

    Web technology provides an opportunity for dentists to showcase their practice philosophy, quality of care, office setting, and staff in a creative manner. Having a Website provides a practice with innovative and cost-effective communications and marketing tools for current and potential patients who use the Internet. The main benefits of using a Website to promote one's practice are: Making office time more productive, tasks more timely, follow-up less necessary Engaging patients in an interactive and visual learning process Providing online forms and procedure examples for patients Projecting a competent and current image Tracking the usage of Web pages. Several options are available when considering the development of a Website. These options range in cost based on customization of the site and ongoing support services, such as site updates, technical assistance, and Web usage statistics. In most cases, Websites are less expensive than advertising in the phone book. Options in creating a Website include building one's own, employing a company that offers Website templates, and employing a company that offers customized sites. These development options and benefits will continue to grow as individuals access the Web and more information and sites become available.

  15. HON label and DISCERN as content quality indicators of health-related websites.

    PubMed

    Khazaal, Yasser; Chatton, Anne; Zullino, Daniele; Khan, Riaz

    2012-03-01

    Content quality indicators are warranted in order to help patients and consumers to judge the content quality of health-related on-line information. The aim of the present study is to evaluate web-based information on health topics and to assess particular content quality indicators like HON (Health on the Net) and DISCERN. The present study is based on the analysis of data issued from six previous studies which assessed with a standardized tool the general and content quality (evidence-based health information) of health-related websites. Keywords related to Social phobia, bipolar disorders, pathological gambling as well as cannabis, alcohol and cocaine addiction were entered into popular World Wide Web search engines. Websites were assessed with a standardized proforma designed to rate sites on the basis of accountability, presentation, interactivity, readability and content quality (evidence-based information). "Health on the Net" (HON) quality label, and DISCERN scale scores were used to verify their efficiency as quality indicators. Of 874 websites identified, 388 were included. Despite an observed association with higher content quality scores, the HON label fails to predict good content quality websites when used in a multiple regression. Sensibility and specificity of a DISCERN score >40 in the detection of good content quality websites were, respectively, 0.45 and 0.96. The DISCERN is a potential quality indicator with a relatively high specificity. Further developments in this domain are warranted in order to facilitate the identification of high-quality information on the web by patients.

    Johnson, Nicholas L.

    2006-01-01

    Purpose: The website provides information about the NASA Orbital Debris Program Office at JSC, which is the lead NASA center for orbital debris research. It is recognized world-wide for its leadership in addressing orbital debris issues. The NASA Orbital Debris Program Office has taken the international lead in conducting measurements of the environment and in developing the technical consensus for adopting mitigation measures to protect users of the orbital environment. Work at the center continues with developing an improved understanding of the orbital debris environment and measures that can be taken to control its growth. Major Contents: Orbital Debris research is divided into the following five broad efforts. Each area of research contains specific information as follows: 1) Modeling - NASA scientists continue to develop and upgrade orbital debris models to describe and characterize the current and future debris environment. Evolutionary and engineering models are described in detail. Downloadable items include a document in PDF format and executable software. 2) Measurements - Measurements of near-Earth orbital debris are accomplished by conducting ground-based and space-based observations of the orbital debris environment. The data from these sources provide validation of the environment models and identify the presence of new sources. Radar, optical and surface examinations are described. External links to related topics are provided. 3) Protection - Orbital debris protection involves conducting hypervelocity impact measurements to assess the risk presented by orbital debris to operating spacecraft and developing new materials and new designs to provide better protection from the environment with less weight penalty. The data from this work provides the link between the environment defined by the models and the risk presented by that environment to operating spacecraft and provides recommendations on design and operations procedures to reduce the risk as

    PubMed

    Househ, Mowafa; Alsughayar, Abdulrahman; Al-Mutairi, Maha

    2013-01-01

    Little information is known about how Saudi health websites compare internationally. The purpose of this paper is to compare two leading Saudi health websites with leading international health websites. The study was conducted as a convenience sample at a graduate health college in Saudi Arabia. A total of 42 students participated in the study. The study found that, in general, English websites have higher levels of performance with regard to quality of information, authority and objectivity, coverage and currency, and design. However, the respondents considered Saudi health websites to be superior with regard to maintaining privacy and security. The results indicate that much more work is needed in designing Saudi Health to make them more trustworthy and credible. The limitations of this work and future research directions are also discussed.

    Ransom, Khadijah S.; Johnson, Grace K.

    2012-01-01

    As a continuation from summer 2012, the Shuttle Case Study Collection has been developed using lessons learned documented by NASA engineers, analysts, and contractors. Decades of information related to processing and launching the Space Shuttle is gathered into a single database to provide educators with an alternative means to teach real-world engineering processes. The goal is to provide additional engineering materials that enhance critical thinking, decision making, and problem solving skills. During this second phase of the project, the Shuttle Case Study Collection website was developed. Extensive HTML coding to link downloadable documents, videos, and images was required, as was training to learn NASA's Content Management System (CMS) for website design. As the final stage of the collection development, the website is designed to allow for distribution of information to the public as well as for case study report submissions from other educators online.

  2. Professionalism and Commercialism on Cosmetic Surgeons' Websites.

    PubMed

    Park, Sung-Yeon; Park, SangHee

    2016-07-15

    This study analyzed the homepages of 250 cosmetic surgeons' websites by focusing on the representation of cosmetic surgery providers, cosmetic surgery recipients, and cosmetic surgery practice itself. Based on a literature review, some common elements of the webpages were preidentified as the indicators of professionalism or commercialism. Subsequently, each homepage was scrutinized for their presence and salience. Overall, cosmetic surgeons' websites were high in professionalism and low in commercialism in their representation of the service providers. In depicting the recipients, the websites were moderate in both professionalism and commercialism. The representation of practice was low in professionalism and moderate in commercialism. Implications of these findings for doctors, regulators, and consumer advocates are discussed and directions for future research are proposed.

    Objective Naltrexone, an opioid antagonist, may facilitate reduction in drinking among young adults. We compared the efficacy and safety of naltrexone administered daily plus targeted dosing with placebo to reduce drinking in heavy drinking young adults. Methods Randomized, double-blind, placebo-controlled study, outpatient research center, March 2008-January 2012. Participants were ages 18-25, reporting ≥ 4 heavy drinking days in the prior 4 weeks. Interventions included naltrexone 25 mg daily plus 25 mg targeted (at most daily) in anticipation of drinking (n = 61) or daily/targeted placebo (n = 67). All received a personalized feedback session and brief counseling every other week. Primary outcomes were percent days heavy drinking (PHDD) and percent days abstinent (PDA) over the 8-week treatment period. Secondary outcomes included drinks/drinking day and percent days with estimated blood alcohol levels ≥0.08 g/dL. Results Of 140 randomized, 128 began treatment, comprising the evaluable sample. During treatment, PHDD (Naltrexone M=21.60, SD=16.05; Placebo M=22.90, SD=13.20) (p=0.58) and PDA (Naltrexone M=56.60, SD=22.52; Placebo M=62.50, SD=15.75) (p=0.39) did not differ by group. Naltrexone significantly reduced drinks per drinking day (Naltrexone M=4.90, SD=2.28; Placebo M=5.90, SD=2.51) (p=0.009) and percentage of drinking days with estimated BAC ≥0.08 g/dL (Naltrexone M=35.36, SD=28.40; Placebo M=45.74, SD=26.80) (p=0.042). There were no serious adverse events. Sleepiness was more common with naltrexone. Conclusions Naltrexone did not reduce frequency of drinking or heavy drinking days, but reduced secondary measures of drinking intensity. While effects were modest, the risk-benefit ratio favors offering naltrexone to help young adult heavy drinkers reduce their drinking. Registration clinicaltrials.gov NCT00568958 PMID:25742208

    Objectives Healthcare costs and usage are rising. Evidence-based online health information may reduce healthcare usage, but the evidence is scarce. The objective of this study was to determine whether the release of a nationwide evidence-based health website was associated with a reduction in healthcare usage. Design Interrupted time series analysis of observational primary care data of healthcare use in the Netherlands from 2009 to 2014. Setting General community primary care. Population 912 000 patients who visited their general practitioners 18.1 million times during the study period. Intervention In March 2012, an evidence-based health information website was launched by the Dutch College of General Practitioners. It was easily accessible and understandable using plain language. At the end of the study period, the website had 2.9 million unique page views per month. Main outcomes measures Primary outcome was the change in consultation rate (consultations/1000 patients/month) before and after the release of the website. Additionally, a reference group was created by including consultations about topics not being viewed at the website. Subgroup analyses were performed for type of consultations, sex, age and socioeconomic status. Results After launch of the website, the trend in consultation rate decreased with 1.620 consultations/1000 patients/month (p<0.001). This corresponds to a 12% decline in consultations 2 years after launch of the website. The trend in consultation rate of the reference group showed no change. The subgroup analyses showed a specific decline for consultations by phone and were significant for all other subgroups, except for the youngest age group. Conclusions Healthcare usage decreased by 12% after providing high-quality evidence-based online health information. These findings show that e-Health can be effective to improve self-management and reduce healthcare usage in times of increasing healthcare costs. PMID:28186945

    2013-01-01

    Background: The exponential use of the internet as a learning resource coupled with varied quality of many websites, lead to a need to identify suitable websites for teaching purposes. Aim: The aim of this study is to develop and to validate a tool, which evaluates the quality of undergraduate medical educational websites; and apply it to the field of pathology. Methods: A tool was devised through several steps of item generation, reduction, weightage, pilot testing, post-pilot modification of the tool and validating the tool. Tool validation included measurement of inter-observer reliability; and generation of criterion related, construct related and content related validity. The validated tool was subsequently tested by applying it to a population of pathology websites. Results and Discussion: Reliability testing showed a high internal consistency reliability (Cronbach's alpha = 0.92), high inter-observer reliability (Pearson's correlation r = 0.88), intraclass correlation coefficient = 0.85 and κ =0.75. It showed high criterion related, construct related and content related validity. The tool showed moderately high concordance with the gold standard (κ =0.61); 92.2% sensitivity, 67.8% specificity, 75.6% positive predictive value and 88.9% negative predictive value. The validated tool was applied to 278 websites; 29.9% were rated as recommended, 41.0% as recommended with caution and 29.1% as not recommended. Conclusion: A systematic tool was devised to evaluate the quality of websites for medical educational purposes. The tool was shown to yield reliable and valid inferences through its application to pathology websites. PMID:24392243

    Objectives To systematically review the effectiveness of community pharmacy-delivered interventions for alcohol reduction, smoking cessation and weight management. Design Systematic review and meta-analyses. 10 electronic databases were searched from inception to May 2014. Eligibility criteria for selecting studies Study design: randomised and non-randomised controlled trials; controlled before/after studies, interrupted times series. Intervention: any relevant intervention set in a community pharmacy, delivered by the pharmacy team. No restrictions on duration, country, age, or language. Results 19 studies were included: 2 alcohol reduction, 12 smoking cessation and 5 weight management. Study quality rating: 6 ‘strong’, 4 ‘moderate’ and 9 ‘weak’. 8 studies were conducted in the UK, 4 in the USA, 2 in Australia, 1 each in 5 other countries. Evidence from 2 alcohol-reduction interventions was limited. Behavioural support and/or nicotine replacement therapy are effective and cost-effective for smoking cessation: pooled OR was 2.56 (95% CI 1.45 to 4.53) for active intervention vs usual care. Pharmacy-based interventions produced similar weight loss compared with active interventions in other primary care settings; however, weight loss was not sustained longer term in a range of primary care and commercial settings compared with control. Pharmacy-based weight management interventions have similar provider costs to those delivered in other primary care settings, which are greater than those delivered by commercial organisations. Very few studies explored if and how sociodemographic or socioeconomic variables moderated intervention effects. Insufficient information was available to examine relationships between effectiveness and behaviour change strategies, implementation factors, or organisation and delivery of interventions. Conclusions Community pharmacy-delivered interventions are effective for smoking cessation, and demonstrate that the pharmacy is a

Program websites serve as an effective recruitment tool for attracting prospective students, yet there is limited research on how school psychology programs use their websites to recruit diverse students. The purpose of this study was to evaluate whether school psychology program websites include sufficient levels of diversity-related content critical for attracting diverse applicants. The website content of 250 professional psychology programs (165 school psychology training programs and 85 clinical and counseling psychology programs) were examined for the presence of themes of diversity and multiculturalism that prospective racially/ethnically and linguistically diverse students deem important for selecting a graduate program. Results indicated that school psychology programs had less diversity-related content on their program's website relative to clinical and counseling psychology programs.' Implications for improving recruitment of racially/ethnically and linguistically diverse students through websites are discussed. (PsycINFO Database Record

    2013-01-01

    Purpose Information about dementia is important for persons with dementia (PWD) and their caregivers and the Internet has become the key source of health information. We reviewed the content and quality of information provided on Canadian websites for Alzheimer’s disease (AD). Methods We used the terms “dementia” and “Alzheimer” in Google to identify Canadian dementia websites. The contents of websites were compared to 16 guideline recommendations provided in Canadian Consensus Conference on Diagnosis and Treatment of Dementia. The quality of information provided on websites was evaluated using the DISCERN instrument. The content and quality of information provided on selected websites were then described. Results Seven websites were identified, three of which provided relatively comprehensive and high-quality information on dementia. Websites frequently provided information about diagnosis of dementia, its natural course, and types of dementia, while other topics were less commonly addressed. The quality of information provided on the websites varied, and many websites had several areas where the quality of information provided was relatively low according to the DISCERN instrument. Conclusions There is variation in the content and quality of dementia websites, although some websites provide high-quality and relatively comprehensive information which would serve as a useful resource for PWD, caregivers, and healthcare providers. Improvements in the content and quality of information provided on AD websites would provide PWD and their caregivers with access to better information. PMID:23440180

  9. Characterization of the Saccharomyces cerevisiae YMR318C (ADH6) gene product as a broad specificity NADPH-dependent alcohol dehydrogenase: relevance in aldehyde reduction.

    PubMed Central

    Larroy, Carol; Fernández, M Rosario; González, Eva; Parés, Xavier; Biosca, Josep A

    2002-01-01

    YMR318C represents an open reading frame from Saccharomyces cerevisiae with unknown function. It possesses a conserved sequence motif, the zinc-containing alcohol dehydrogenase (ADH) signature, specific to the medium-chain zinc-containing ADHs. In the present study, the YMR318C gene product has been purified to homogeneity from overexpressing yeast cells, and found to be a homodimeric ADH, composed of 40 kDa subunits and with a pI of 5.0-5.4. The enzyme was strictly specific for NADPH and was active with a wide variety of substrates, including aliphatic (linear and branched-chain) and aromatic primary alcohols and aldehydes. Aldehydes were processed with a 50-fold higher catalytic efficiency than that for the corresponding alcohols. The highest k(cat)/K(m) values were found with pentanal>veratraldehyde > hexanal > 3-methylbutanal >cinnamaldehyde. Taking into consideration the substrate specificity and sequence characteristics of the YMR318C gene product, we have proposed this gene to be called ADH6. The disruption of ADH6 was not lethal for the yeast under laboratory conditions. Although S. cerevisiae is considered a non lignin-degrading organism, the catalytic activity of ADHVI can direct veratraldehyde and anisaldehyde, arising from the oxidation of lignocellulose by fungal lignin peroxidases, to the lignin biodegradation pathway. ADHVI is the only S. cerevisiae enzyme able to significantly reduce veratraldehyde in vivo, and its overexpression allowed yeast to grow under toxic concentrations of this aldehyde. The enzyme may also be involved in the synthesis of fusel alcohols. To our knowledge this is the first NADPH-dependent medium-chain ADH to be characterized in S. cerevisiae. PMID:11742541

  11. Measuring interactivity on tobacco control websites.

    PubMed

    Freeman, Becky; Chapman, Simon

    2012-08-01

    With the increased reach of Web 2.0, Internet users expect webpages to be interactive. No studies have been conducted to assess whether tobacco control-relevant sites have implemented these features. The authors conducted an analysis of an international sample of tobacco control-relevant websites to determine their level of interactivity. The sample included 68 unique websites selected from Google searches in 5 countries, on each country's Google site, using the term smoking. The 68 sites were analyzed for 10 categories of interactive tools. The most common type of interactive content found on 46 (68%) of sites was for multimedia featuring content that was not primarily text based, such as photo galleries, videos, or podcasts. Only 11 (16%) websites-outside of media sites-allowed people to interact and engage with the site owners and other users by allowing posting comments on content and/or hosting forums/discussions. Linkages to social networking sites were low: 17 pages (25%) linked to Twitter, 15 (22%) to Facebook, and 11 (16%) to YouTube. Interactivity and connectedness to online social media appears to still be in its infancy among tobacco control-relevant sites.

  12. Quantitative Information on Oncology Prescription Drug Websites.

    PubMed

    Sullivan, Helen W; Aikin, Kathryn J; Squiers, Linda B

    2016-09-02

    Our objective was to determine whether and how quantitative information about drug benefits and risks is presented to consumers and healthcare professionals on cancer-related prescription drug websites. We analyzed the content of 65 active cancer-related prescription drug websites. We assessed the inclusion and presentation of quantitative information for two audiences (consumers and healthcare professionals) and two types of information (drug benefits and risks). Websites were equally likely to present quantitative information for benefits (96.9 %) and risks (95.4 %). However, the amount of the information differed significantly: Both consumer-directed and healthcare-professional-directed webpages were more likely to have quantitative information for every benefit (consumer 38.5 %; healthcare professional 86.1 %) compared with every risk (consumer 3.1 %; healthcare professional 6.2 %). The numeric and graphic presentations also differed by audience and information type. Consumers have access to quantitative information about oncology drugs and, in particular, about the benefits of these drugs. Research has shown that using quantitative information to communicate treatment benefits and risks can increase patients' and physicians' understanding and can aid in treatment decision-making, although some numeric and graphic formats are more useful than others.

  13. Customer privacy on UK healthcare websites.

    2006-09-01

    Privacy has been and continues to be one of the key challenges of an age devoted to the accumulation, processing, and mining of electronic information. In particular, privacy of healthcare-related information is seen as a key issue as health organizations move towards the electronic provision of services. The aim of the research detailed in this paper has been to analyse privacy policies on popular UK healthcare-related websites to determine the extent to which consumer privacy is protected. The author has combined approaches (such as approaches focused on usability, policy content, and policy quality) used in studies by other researchers on e-commerce and US healthcare websites to provide a comprehensive analysis of UK healthcare privacy policies. The author identifies a wide range of issues related to the protection of consumer privacy through his research analysis using quantitative results. The main outcomes from the author's research are that only 61% of healthcare-related websites in their sample group posted privacy policies. In addition, most of the posted privacy policies had poor readability standards and included a variety of privacy vulnerability statements. Overall, the author's findings represent significant current issues in relation to healthcare information protection on the Internet. The hope is that raising awareness of these results will drive forward changes in the industry, similar to those experienced with information quality.

  15. Clinical pathology of alcohol.

    PubMed Central

    Marks, V

    1983-01-01

    There is good though not conclusive evidence that a small to modest average daily intake of alcohol--that is, 20-30 g/day is associated with increased longevity due mainly to a reduction in death from cardiovascular disease. Larger average daily alcohol intakes--especially those in excess of 60 g/day for men and 40 g/day for women--are associated with gradually increasing morbidity and mortality rates from a variety of diseases. Alcohol may be unrecognised as the cause of somatic disease, which can occur without overt psychosocial evidence of alcohol abuse, unless the index of suspicion is high and a thorough drink history obtained. Laboratory tests for the detection and/or confirmation of alcohol abuse are useful but subject to serious limitations being neither as sensitive nor specific as sometimes believed. The value of random blood and/or breath alcohol measurements, in outpatients, as an aid to diagnosis of alcohol-induced organic disease is probably not sufficiently appreciated and, though relatively insensitive, is highly specific.

    Nath, Chinmoy; Huh, Jina; Adupa, Abhishek Kalyan

    2016-01-01

    Background An increasing number of people visit online health communities to seek health information. In these communities, people share experiences and information with others, often complemented with links to different websites. Understanding how people share websites can help us understand patients’ needs in online health communities and improve how peer patients share health information online. Objective Our goal was to understand (1) what kinds of websites are shared, (2) information quality of the shared websites, (3) who shares websites, (4) community differences in website-sharing behavior, and (5) the contexts in which patients share websites. We aimed to find practical applications and implications of website-sharing practices in online health communities. Methods We used regular expressions to extract URLs from 10 WebMD online health communities. We then categorized the URLs based on their top-level domains. We counted the number of trust codes (eg, accredited agencies’ formal evaluation and PubMed authors’ institutions) for each website to assess information quality. We used descriptive statistics to determine website-sharing activities. To understand the context of the URL being discussed, we conducted a simple random selection of 5 threads that contained at least one post with URLs from each community. Gathering all other posts in these threads resulted in 387 posts for open coding analysis with the goal of understanding motivations and situations in which website sharing occurred. Results We extracted a total of 25,448 websites. The majority of the shared websites were .com (59.16%, 15,056/25,448) and WebMD internal (23.2%, 5905/25,448) websites; the least shared websites were social media websites (0.15%, 39/25,448). High-posting community members and moderators posted more websites with trust codes than low-posting community members did. The heart disease community had the highest percentage of websites containing trust codes compared to

    Digital interventions are available to help people reduce their alcohol consumption, but it is not known who uses these interventions and how this treatment-seeking group compares with the general population of drinkers. The study objective was to compare the socio-demographic and drinking characteristics of users of the 'Drinks Meter' smartphone app with the general population of drinkers in England and website users of the same intervention. Data were used from the Drinks Meter app and website, and a nationally representative cross-sectional survey in England (Alcohol Toolkit Study). Participants were drinkers aged 16+ in England. Data were collected on participants' age, gender, region, sexual orientation, social grade and AUDIT score. Regression analyses were conducted to assess differences in socio-demographic and drinking characteristics between samples. Drinks Meter app users, compared with drinkers of the general population, were younger, more likely to be from the South, not heterosexual, less likely to be of a lower social grade and had a higher mean AUDIT score. Drinks Meter app users were younger than website users and reported greater alcohol consumption and related harms. Drinkers using the Drinks Meter app are more likely to be younger and report greater alcohol consumption and related harms compared with the general population of drinkers in England and website users of the same intervention. Apps that provide feedback on drinking appear to be reaching those who report greater alcohol consumption and related harms.

    2012-10-01

    Nowadays, there are many peoples who access to the internet to search for a proper hospital with their desired medical services. Hence, the website quality of hospitals or medical centers is very important to help patients/users. However, to design high qualitative medical websites, we should first know the medical quality metrics. Then, we should try to find a way to assess different medical websites based on the quality metrics. In fact, medical websites may have a significant role to increase the society's knowledge about people health, provided services for patients etc. Thus, it is necessary to design a framework to evaluate the quality of these websites. Even though there are many medical websites, unfortunately, there are a few studies about quality analysis of medical/hospital websites. In this paper, we propose a qualitative framework to assess different medical websites. The proposed framework consists of 7 main categories, each having different metrics. Finally, to show how these metrics can help designers to assess the websites quality, we have considered 3 different hospitals as case studies. We asked different people including doctors, website designers, and usual peoples to evaluate our defined metrics on each case study. At the end, the results are shown through different charts.

    To date, there have been efforts toward creating better health information access for Deaf American Sign Language (ASL) users. However, the usability of websites with access to health information in ASL has not been evaluated. Our article focuses on the usability of four health websites that include ASL videos. We seek to obtain ASL users' perspectives on the navigation of these ASL-accessible websites, finding the health information that they needed, and perceived ease of understanding ASL video content. ASL users (n = 32) were instructed to find specific information on four ASL-accessible websites, and answered questions related to (a) navigation to find the task, (b) website usability, and (c) ease of understanding ASL video content for each of the four websites. Participants also gave feedback on what they would like to see in an ASL health library website, including the benefit of added captioning and/or signer model to medical illustration of health videos. Participants who had lower health literacy had greater difficulty in finding information on ASL-accessible health websites. This article also describes the participants' preferences for an ideal ASL-accessible health website, and concludes with a discussion on the role of accessible websites in promoting health literacy in ASL users.

  2. A review of public opinion towards alcohol controls in Australia

    PubMed Central

    2011-01-01

    Background Increasing concern about the negative impact of alcohol on the Australian community has renewed calls for tighter regulatory controls. This paper reviews levels of and trends in public support for liquor control regulations, regulation of alcohol promotions, and alcohol pricing and taxation reforms in Australia between 1998 and 2009. Methods Six electronic databases and twenty public health and alcohol organisation websites were searched for research literature, reports and media releases describing levels of public support for alcohol controls. Only studies which randomly selected participants were included. Results Twenty-one studies were included in the review. The majority of the Australian public support most proposed alcohol controls. Levels of support are divided between targeted and universal controls. Conclusions Implementation of targeted alcohol policies is likely to be strongly supported by the Australian public, but universal controls are liable to be unpopular. Policy makers are provided with insights into factors likely to be associated with higher public support. PMID:21272368

  3. Biomass resources for alcohol fuels

    NASA Astrophysics Data System (ADS)

    MacDowell, J. E.

    The production of alcohol fuel from biomass represents a fast and practical means of adding to the dwindling petroleum supply. The biomass feed-stocks which will feed the alcohol distilleries must be carefully selected. Using food chain biomass crops for conversion to alcohol will cause a reduction in the amount of food available and increase the cost of food and alcohol feedstocks. The food chains should not be drastically interrupted, and agricultural economic balances should not be altered. Various alternatives to alcohol production are presented, which lie within the confines of selected biomass feedstocks and will not interrupt normal agricultural activities. A corn processing and distillation process is shown graphically as an example; the biomass to alcohol conversion potential of feedstocks is given, and the potential cropland for conversion in the U.S.A. is shown as a percentage of the nation's total land area.

    Background Health promotion and risk reduction are essential components of sexual health care. However, it can be difficult to prioritize these within busy clinical services. Digital interventions may provide a new method for supporting these. Objective The MenSS (Men’s Safer Sex) website is an interactive digital intervention developed by a multidisciplinary team, which aims to improve condom use in men who have sex with women (MSW). This paper describes the content of this intervention, and the rationale for it. Methods Content was informed by a literature review regarding men’s barriers to condom use, workshops with experts in sexual health and technology (N=16) and interviews with men in sexual health clinics (N=20). Data from these sources were analyzed thematically, and synthesized using the Behavior Change Wheel framework. Results The MenSS intervention is a website optimized for delivery via tablet computer within a clinic waiting room setting. Key targets identified were condom use skills, beliefs about pleasure and knowledge about risk. Content was developed using behavior change techniques, and interactive website features provided feedback tailored for individual users. Conclusions This paper provides a detailed description of an evidence-based interactive digital intervention for sexual health, including how behavior change techniques were translated into practice within the design of the MenSS website. Triangulation between a targeted literature review, expert workshops, and interviews with men ensured that a range of potential influences on condom use were captured. PMID:26142304

    5-((R)-1-Hydroxyethyl)-furo[2,3-c]pyridine ((R)-FPH) is a useful chiral building block in the synthesis of pharmaceuticals. An NADH-dependent alcohol dehydrogenase (AFPDH) isolated from Candida maris catalyzed the reduction of 5-acetylfuro[2,3-c]pyridine (AFP) to (R)-FPH with 100% enantiomeric excess. The gene encoding AFPDH was cloned and sequenced. The AFPDH gene comprises 762 bp and encodes a polypeptide of 27,230 Da. The deduced amino acid sequence showed a high degree of similarity to those of other members of the short-chain alcohol dehydrogenase superfamily. The AFPDH gene was overexpressed in Escherichia coli under the control of the lac promoter. One L of the cultured broth of an E. coli transformant coexpressing AFPDH and the glucose dehydrogenase (GDH) gene reduced 250 g of AFP to (R)-FPH in an organic solvent two-phase system. Under coupling with NADH regeneration using 2-propanol, 1 L of the cultured broth of an E. coli transformant expressing the AFPDH gene reduced 150 g of AFP to (R)-FPH. The optical purity of the (R)-FPH formed was 100% enantiomeric excess under both reaction conditions.

    Ethanol is an alcohol made from grain that can be blended with gasoline to extend petroleum supplies and to increase gasoline octane levels. Congressional proposals to encourage greater use of alternative fuels could increase the demand for ethanol. This report evaluates the growth potential of the ethanol industry to meet future demand increases and the impacts increased production would have on American agriculture and the federal budget. It is found that ethanol production could double or triple in the next eight years, and that American farmers could provide the corn for this production increase. While corn growers would benefit, other agricultural segments would not; soybean producers, for example could suffer for increased corn oil production (an ethanol byproduct) and cattle ranchers would be faced with higher feed costs because of higher corn prices. Poultry farmers might benefit from lower priced feed. Overall, net farm cash income should increase, and consumers would see slightly higher food prices. Federal budget impacts would include a reduction in federal farm program outlays by an annual average of between $930 million (for double current production of ethanol) to $1.421 billion (for triple production) during the eight-year growth period. However, due to an partial tax exemption for ethanol blended fuels, federal fuel tax revenues could decrease by between $442 million and $813 million.

  11. Design and implementation of website information disclosure assessment system.

    PubMed

    2015-01-01

    Internet application technologies, such as cloud computing and cloud storage, have increasingly changed people's lives. Websites contain vast amounts of personal privacy information. In order to protect this information, network security technologies, such as database protection and data encryption, attract many researchers. The most serious problems concerning web vulnerability are e-mail address and network database leakages. These leakages have many causes. For example, malicious users can steal database contents, taking advantage of mistakes made by programmers and administrators. In order to mitigate this type of abuse, a website information disclosure assessment system is proposed in this study. This system utilizes a series of technologies, such as web crawler algorithms, SQL injection attack detection, and web vulnerability mining, to assess a website's information disclosure. Thirty websites, randomly sampled from the top 50 world colleges, were used to collect leakage information. This testing showed the importance of increasing the security and privacy of website information for academic websites.

    We review programs and policies to prevent children from accessing alcohol marketing online. To update the literature, we present our recent studies that assess (i) in-built barriers to underage access to alcohol brand websites and (ii) commercial internet filters. Alcohol websites typically had poor filter systems for preventing entry of underage persons; only half of the sites required the user to provide a date of birth, and none had any means of preventing users from trying again. Even the most effective commercial internet filters allowed access to one-third of the sites we examined.

    2014-01-01

    Background: Charities exist to pursue a public benefit, whereas corporations serve the interests of their shareholders. The alcohol industry uses corporate social responsibility activities to further its interests in influencing alcohol policy. Many charities also seek to influence alcohol and other policy. The aim of this study was to explore relationships between the alcohol industry and charities in the UK and whether these relationships may be used as a method of influencing alcohol policy. Methods: The charity regulator websites for England and Wales and for Scotland were the main data sources used to identify charities involved in UK alcohol policy making processes and/or funded by the alcohol industry. Results: Five charities were identified that both receive alcohol industry funding and are active in UK alcohol policy processes: Drinkaware; the Robertson Trust; British Institute of Innkeeping; Mentor UK and Addaction. The latter two are the sole remaining non-industry non-governmental members of the controversial responsibility deal alcohol network, from which all other public health interests have resigned. Conclusion: This study raises questions about the extent to which the alcohol industry is using UK charities as vehicles to further their own interests in UK alcohol policy. Mechanisms of industry influence in alcohol policy making globally is an important target for further investigations designed to assist the implementation of evidenced-based policies. PMID:24913316

    The increase adoption of Internet among young users in Malaysia provides high prospect for online seller. Young users aged between 18 and 25 years old are important to online sellers because they are actively involved in online purchasing and this group of online buyers is expected to dominate future online market. Therefore, examining online sellers’ website quality and online buyers’ purchase intention is crucial. Based on the Theory of planned behavior (TPB), a conceptual model of online sellers’ website quality and purchase intention of online buyers was developed. E-tailQ instrument was adapted in this study which composed of website design, reliability/fulfillment, security, privacy & trust, and customer service. Using online questionnaire and convenience sampling procedure, primary data were obtained from 240 online buyers aged between 18 to 25 years old. It was discovered that website design, website reliability/fulfillment, website security, privacy & trust, and website customer service positively and significantly influence intention of online buyers to continuously purchase via online channels. This study concludes that online sellers’ website quality is important in predicting online buyers’ purchase intention. Recommendation and implication of this study were discussed focusing on how online sellers should improve their website quality to stay competitive in online business.

    The Internet is commonly used to seek health-related information, but little is known about the quality of websites on developmental disabilities. Therefore, we sought to evaluate the characteristics and quality of websites located by searching ten common terms related to developmental disabilities and explore relations between website characteristics and website quality in order to make recommendations on ways to ensure locating good online information. We located 208 unique websites in our November 2012 US searches of Google and Bing. Two independent coders evaluated 10 characteristics of the websites and two different coders assessed the quality of the websites. From the 208 websites, 104 (50%) provided relevant information about the disability being searched. Of these 104 websites, those found to be of highest quality were least likely to be a sponsored result, contain advertisements, be from a for-profit company, and did contain references to peer-reviewed publications or had a top-level domain of .gov or .org. Individuals with developmental disabilities and their family members who choose to obtain disability-related information online should remain vigilant to ensure that they locate high-quality and accurate information and should not replace information obtained from health-care professionals and educational specialists with information found online.

    Prenatal ethanol exposure is associated with an increased incidence of depressive disorders in patient populations. However, the mechanisms that link prenatal ethanol exposure and depression are unknown. Several recent studies have implicated reduced brain-derived neurotrophic factor (BDNF) levels in the hippocampal formation and frontal cortex as important contributors to the etiology of depression. In the present studies, we sought to determine whether prenatal ethanol exposure is associated with behaviors that model depression, as well as with reduced BDNF levels in the hippocampal formation and/or medial frontal cortex, in a mouse model of fetal alcohol spectrum disorder (FASD). Compared to control adult mice, prenatal ethanol-exposed adult mice displayed increased learned helplessness behavior and increased immobility in the Porsolt forced swim test. Prenatal ethanol exposure was associated with decreased BDNF protein levels in the medial frontal cortex, but not the hippocampal formation, while total BDNF mRNA and BDNF transcripts containing exons III, IV or VI were reduced in both the medial frontal cortex and the hippocampal formation of prenatal ethanol-exposed mice. These results identify reduced BDNF levels in the medial frontal cortex and hippocampal formation as potential mediators of depressive disorders associated with FASD.

    "􀀶oftware engineering" is different from the general professional courses, it is born for getting rid of the software crisis and adapting to the development of software industry, it is a theory course, especially a practical course. However, due to the own characteristics of software engineering curriculum, in the daily teaching process, concerning theoretical study, students may feel boring, obtain low interest in learning and poor test results and other problems. ASPNET design technique is adopted and Access 2007 database is used for system to design and realize "Software Engineering" teaching website. System features mainly include theoretical teaching, case teaching, practical teaching, teaching interaction, database, test item bank, announcement, etc., which can enhance the vitality, interest and dynamic role of learning.

  1. A website for astronomical news in Spanish

    Ortiz-Gil, A.

    2008-06-01

    Noticias del Cosmos is a collection of web pages within the Astronomical Observatory of the University of Valencia's website where we publish short daily summaries of astronomical press releases. Most, if not all of, the releases are originally written in English, and often Spanish readers may find them difficult to understand because not many people are familiar with the scientific language employed in these releases. Noticias del Cosmos has two principal aims. First, we want to communicate the latest astronomical news on a daily basis to a wide Spanish-speaking public who would otherwise not be able to read them because of the language barrier. Second, daily news can be used as a tool to introduce the astronomical topics of the school curriculum in a more immediate and relevant way. Most of the students at school have not yet reached a good enough level in their knowledge of English to fully understand a press release, and Noticias del Cosmos offers them and their teachers this news in their mother tongue. During the regular programme of school visits at the Observatory we use the news as a means of showing that there is still a lot to be discovered. So far the visits to the website have been growing steadily. Between June 2003 and June 2007 we had more than 30,000 visits (excluding 2006). More than 50% of the visits come from Spain, followed by visitors from South and Central America. The feedback we have received from teachers so far has been very positive, showing the usefulness of news items in the classroom when teaching astronomy.

  2. Solar-Driven Reduction of Aqueous Protons Coupled to Selective Alcohol Oxidation with a Carbon Nitride-Molecular Ni Catalyst System.

    Solar water-splitting represents an important strategy toward production of the storable and renewable fuel hydrogen. The water oxidation half-reaction typically proceeds with poor efficiency and produces the unprofitable and often damaging product, O2. Herein, we demonstrate an alternative approach and couple solar H2 generation with value-added organic substrate oxidation. Solar irradiation of a cyanamide surface-functionalized melon-type carbon nitride ((NCN)CNx) and a molecular nickel(II) bis(diphosphine) H2-evolution catalyst (NiP) enabled the production of H2 with concomitant selective oxidation of benzylic alcohols to aldehydes in high yield under purely aqueous conditions, at room temperature and ambient pressure. This one-pot system maintained its activity over 24 h, generating products in 1:1 stoichiometry, separated in the gas and solution phases. The (NCN)CNx-NiP system showed an activity of 763 μmol (g CNx)(-1) h(-1) toward H2 and aldehyde production, a Ni-based turnover frequency of 76 h(-1), and an external quantum efficiency of 15% (λ = 360 ± 10 nm). This precious metal-free and nontoxic photocatalytic system displays better performance than an analogous system containing platinum instead of NiP. Transient absorption spectroscopy revealed that the photoactivity of (NCN)CNx is due to efficient substrate oxidation of the material, which outweighs possible charge recombination compared to the nonfunctionalized melon-type carbon nitride. Photoexcited (NCN)CNx in the presence of an organic substrate can accumulate ultralong-lived "trapped electrons", which allow for fuel generation in the dark. The artificial photosynthetic system thereby catalyzes a closed redox cycle showing 100% atom economy and generates two value-added products, a solar chemical, and solar fuel.

    One out of 2 Americans report drinking on a routine basis, making the excessive consumption of alcohol the third leading cause of preventable death in America (). Alcoholism and depression are common comorbidities that home healthcare professionals frequently encounter. To achieve the best patient outcomes, alcoholism should be addressed initially. Although all age groups are at risk, alcoholism and depression occur in more than 8 percent of older adults. Prevention through identifying alcohol use early in adolescence is vital to reduce the likelihood of alcohol dependence. This article provides an overview of the long-term effects of alcohol abuse, including alcoholic cirrhosis and hepatic encephalopathy. The diagnostic criteria for substance dependence and ideas for nonthreatening screening questions to use with patients who are adolescent or older are discussed. While providing patient care, home healthcare nurses share the patient's intimate home environment. This environment is perceived as a safe haven by the patient and home care nurses can take advantage of counseling and treatment opportunities in this nonthreatening environment.

    Alcohol use contributes to morbidity and mortality in developing countries by increasing the risk of trauma and disease, including alcohol dependence. Limited research addresses determinants of alcohol use beyond the individual level in sub-Saharan Africa. We test the association of community collective efficacy and alcohol outlet density with young men's drinking in a cross-sectional, locally representative survey conducted in rural northeast South Africa. Informal social control and cohesion show protective associations with men's heavy drinking, while alcohol outlet density is associated with more potential problem drinking. These findings provide initial support for intervening at the community level to promote alcohol reduction.

    Which features of websites are important for users' perceptions regarding aesthetics or usability? This study investigates how evaluations of aesthetic appeal and usability depend on high vs. low spatial frequencies. High spatial frequencies convey information on fine details, whereas low spatial frequencies convey information about the global layout. Participants rated aesthetic appeal and usability of 50 website screenshots from different domains. Screenshots were presented unfiltered, low-pass filtered with blurred targets or high-pass filtered with high-pass filtered targets. The main result is that low spatial frequencies can be seen to have a unique contribution in perceived website aesthetics, thus confirming a central prediction from processing fluency theory. There was no connection between low spatial frequencies and usability evaluations, whereas strong correlations were found between ratings of high-pass filtered websites and those of unfiltered websites in aesthetics and usability. This study thus offers a new perspective on the biological basis of users' website perceptions. This research links ergonomics to neurocognitive models of visual processing. This paper investigates how high and low spatial frequencies, which are neurologically processed in different visual pathways, independently contribute to users' perceptions of websites. This is very relevant for theories of website perceptions and for practitioners of web design.

    2015-01-01

    Nursing Home Compare (NHC) is a federal government website providing information for selecting a nursing home. However, not many consumers were aware of or can locate the site. This study analyzed 50 official state and District of Columbia websites from September through December 2013. Using Google "inlink:" operator, this study evaluated the visibility and findability of NHC links in each state-level website. The results show that a link to NHC is available in all states except for Connecticut, Florida, and Michigan. Although it took only 4.7 clicks on average to the page with a NHC link, consumers may still have difficulty to find NHC from a state website. This article provides a snapshot of the visibility and findability of NHC and indicates a need for further investigation of promising website dissemination strategies not yet adequately evaluated.

    2013-06-01

    Gamification design is considered as the predictor of collaborative storytelling websites' success. Although aforementioned studies have mentioned a broad range of factors that may influence gamification, they neither depicted the actual design features nor relative attractiveness among them. This study aims to identify attractive gamification features for collaborative storytelling websites. We first constructed a hierarchical system structure of gamification design of collaborative storytelling websites and conducted a focus group interview with eighteen frequent users to identify 35gamification features. After that, this study determined the relative attractiveness of these gamification features by administrating an online survey to 6333 collaborative storytelling websites users. The results indicated that the top 10 most attractive gamification features could account for more than 50% of attractiveness among these 35 gamification features. The feature of unpredictable time pressure is important to website users, yet not revealed in previous relevant studies. Implications of the findings were discussed.

    Careers provision for young people in the UK is being re-formulated on the basis of a central role for career websites but this policy is based on unproven assumptions about their value. In this article we consider the use and impact of the two main career websites in Scotland on pupils' career management skills. We found that pupils at risk of not achieving positive post-school destinations were less likely to use the websites, as were minority ethnic pupils. Although similar in functions, the two websites differed in their effect: one had no impact while the other impacted on only one aspect of pupils' career management skills. Careers policy needs to be informed by more extensive research on career websites.

    An online solid-phase microextraction coupled liquid chromatography-electrospray ionization-ion trap mass spectrometry was developed for the analysis of trace R- and S-4-phenyl-2-butanol (R- and S-pbol) in salt rich cell culture of Saccharomyces cerevisiae catalyzed stereoselective reduction of 4-pheny-2-butanone (pbone). A Supel-Q PLOT capillary column was used for the extraction and deionized distilled water was used as the extraction mobile phase. The extraction flow rate and extraction time were at 0.1 mL min(-1) and 0.95 min, respectively. The three target analytes, pbone, R-pbol, and S-4-pbol, were desorbed and eluted by the mobile phase of water/methanol/isopropanol (55/25/20, v/v/v) with a flow rate of 0.5 mL min(-1) and analyzed by a chiral column. The mass spectrometric detection of the three target analytes was in positive ion mode with the signal [M+Na](+). The matrix-matched external standard calibration curves with linear concentration range between 0 and 50 μg mL(-1) were used for quantitative analysis. The linear regression correlation coefficients (r(2)) of the standard calibration curves were between 0.9950 and 0.9961. The yeast mediated reduction was performed with a recation culture of yeast incubation culture/glycerol (70/30, v/v) for 4 days. This biotransformation possessed 82.3% yield and 92.9% S-enantomeric excess. The limit of detection (LOD)/limit of quantification (LOQ) for pbone, R-pbol, and S-pbol was 0.02/0.067, 0.01/0.033, and 0.01/0.033 μg mL(-1), respectively. The intra-day and inter-day precisions from repeated measurements were 10.8-21.1% and 11.6-18.7%, respectively. The analysis accuracy from spike recovery was 84-91%.

However, the goal of predicting chemical toxicity in its many manifestations, the `T' in 'ADMET' (adsorption, distribution, metabolism, elimination, toxicity), remains one of the most difficult and largely unmet challenges in a chemical screening paradigm [1]. It is widely acknowledged that the single greatest hurdle to improving structure-activity relationship (SAR) toxicity prediction capabilities, in both the pharmaceutical and environmental regulation arenas, is the lack of suffici

    An academic health sciences library wanted to redesign its website to provide better access to health information in the community. Virtual reference data were used to provide information about user searching behavior. This study analyzed three years (2012-2014) of virtual reference data, including e-mail questions, text messaging, and live chat transcripts, to evaluate the library website for redesigning, especially in areas such as the home page, patrons' terminology, and issues prompting patrons to ask for help. A coding system based on information links in the current library website was created to analyze the data.

    1990-01-01

    Alcohol dehydrogenase activity was measured in samples of liver tissue from a group of alcoholic and non-alcoholic subjects to determine whether decreased liver alcohol dehydrogenase activity is a consequence of ethanol consumption or liver damage. The alcoholic patients were classified further into the following groups: control subjects with no liver disease (group 1), subjects with non-cirrhotic liver disease (group 2), and subjects with cirrhotic liver disease (group 3). The non-alcoholic subjects were also divided, using the same criteria, into groups 4, 5, and 6, respectively. The analysis of the results showed no significant differences when mean alcohol dehydrogenase activities of alcoholic and non-alcoholic patients with similar degrees of liver pathology were compared (groups 1 v 4, 2 v 5, and 3 v 6. Alcohol dehydrogenase activity was, however, severely reduced in patients with liver disease compared with control subjects. Our findings suggest that alcohol consumption does not modify hepatic alcohol dehydrogenase activity. The reduction in specific alcohol dehydrogenase activity in alcoholic liver disease is a consequence of liver damage. PMID:2379876

    Consumption of alcohol was investigated in two groups of pregnant women: an intervention group (n = 58) (two structured interviews during pregnancy including counseling focused on reduction of alcohol consumption and potential benefits to the fetus, and interview after delivery), and a control group (n = 74) (interview after delivery). Prepregnancy 80% of the women were light or moderate alcohol consumers, and 20% teetotalers. Pregnancy considerably reduced alcohol consumption in both groups. 66% abstained from alcohol during pregnancy, and use of liquor nearly ceased. The changes in alcohol consumption occurred independently to the intervention program. Strategy for reducing alcohol consumption during pregnancy should include a structured alcohol anamnesis at the first ante-natal visit, accompanied by counseling focused on reduction of alcohol consumption. More extensive intervention programs may be reserved for pregnancies at higher risk (high-consumers, abusers).

    Despite the development of the web geographical information system (web GIS), many useful spatial analysis functions are ignored in the system implementation. As Kashgar is rich in natural resources, it is of great significance to monitor the ample natural resource and environment situation in the region. Therefore, with multiple uses of spatial analysis, resources and environment monitoring website of Kashgar was built. Functions of water, vegetation, ice and snow extraction, task management, change assessment as well as thematic mapping and reports based on TM remote sensing images were implemented in the website. The design of the website was presented based on database management tier, the business logic tier and the top-level presentation tier. The vital operations of the website were introduced and the general performance was evaluated.

  8. Assessing Website Pharmacy Drug Quality: Safer Than You Think?

    PubMed Central

    Bate, Roger; Hess, Kimberly

    2010-01-01

    Background Internet-sourced drugs are often considered suspect. The World Health Organization reports that drugs from websites that conceal their physical address are counterfeit in over 50 percent of cases; the U.S. Food and Drug Administration (FDA) works with the National Association of Boards of Pharmacy (NABP) to regularly update a list of websites likely to sell drugs that are illegal or of questionable quality. Methods and Findings This study examines drug purchasing over the Internet, by comparing the sales of five popular drugs from a selection of websites stratified by NABP or other ratings. The drugs were assessed for price, conditions of purchase, and basic quality. Prices and conditions of purchase varied widely. Some websites advertised single pills while others only permitted the purchase of large quantities. Not all websites delivered the exact drugs ordered, some delivered no drugs at all; many websites shipped from multiple international locations, and from locations that were different from those advertised on the websites. All drug samples were tested against approved U.S. brand formulations using Raman spectrometry. Many (17) websites substituted drugs, often in different formulations from the brands requested. These drugs, some of which were probably generics or perhaps non-bioequivalent copy versions, could not be assessed accurately. Of those drugs that could be assessed, none failed from “approved”, “legally compliant” or “not recommended” websites (0 out of 86), whereas 8.6% (3 out of 35) failed from “highly not recommended” and unidentifiable websites. Conclusions Of those drugs that could be assessed, all except Viagra® passed spectrometry testing. Of those that failed, few could be identified either by a country of manufacture listed on the packaging, or by the physical location of the website pharmacy. If confirmed by future studies on other drug samples, then U.S. consumers should be able to reduce their risk by

    Babies' parents and people who look for information about vaccination often visit anti-vaccine movement's websites, blogs by naturopathic physicians or natural and alternative medicine practitioners. The aim of this work is to provide a quantitative analysis on the type of information available to Italian people regarding vaccination and a quality analysis of websites retrieved through our searches. A quality score was created to evaluate the technical level of websites. A research was performed through Yahoo, Google, and MSN using the keywords "vaccine" and "vaccination," with the function "OR" in order to identify the most frequently used websites. The 2 keywords were input in Italian, and the first 15 pages retrieved by each search engine were analyzed. 149 websites were selected through this methodology. Fifty-three per cent of the websites belonged to associations, groups, or scientific companies, 32.2% (n = 48) consisted of a personal blog and 14.8% (n = 22) belonged to some of the National Health System offices. Among all analyzed websites, 15.4% (n = 23) came from anti-vaccine movement groups. 37.6% reported webmaster name, 67.8% webmaster e-mail, 28.6% indicated the date of the last update and 46.6% the author's name. The quality score for government sites was higher on average than anti-vaccine websites; although, government sites don't use Web 2.0 functions, as the forums.: National Health System institutions who have to promote vaccination cannot avoid investing in web communication because it cannot be managed by private efforts but must be the result of Public Health, private and scientific association, and social movement synergy.

    2013-01-01

    Background The unavailability of Internet pharmacy websites may impact a consumer’s drug purchases and health care. Objective To address the issue of attrition, a defined set of Canadian Internet pharmacy websites was examined at three separate time intervals. Methods In February to March 2006, 117 distinct, fully functional “Canadian Internet pharmacy” websites were located using the advanced search options of Google and the uniform resource locator (URL) for each website was recorded. To determine website attrition, each of the 117 websites obtained and recorded from the previous study was revisited at two later periods of time within a 4-year period. Results After approximately 4 years and 5 months, only 59 (50.4%) sites were found in the original state. Thirty-four sites (29.1%) had moved to a new URL address and were not functioning as the original Internet pharmacy. For 24 sites (20.5%) the viewer was redirected to another Canadian Internet pharmacy site. Conclusion Of concern for patients if Internet pharmacy sites were suddenly inaccessible would be the disruption of continuity of care. PMID:23983491

    Despite the widespread increase in online poker playing and the risk related to excessive poker playing, research on online poker websites is still lacking with regard to pathological gambling prevention strategies offered by the websites. The aim of the present study was to assess the pathological gambling-related prevention strategies of online poker websites. Two keywords ("poker" and "poker help") were entered into two popular World Wide Web search engines. The first 20 links related to French and English online poker websites were assessed. Seventy-four websites were assessed with a standardized tool designed to rate sites on the basis of accountability, interactivity, prevention strategies, marketing, and messages related to poker strategies. Prevention strategies appeared to be lacking. Whereas a substantial proportion of the websites offered incitation to gambling such as betting "tips," few sites offered strategies to prevent or address problem gambling. Furthermore, strategies related to poker, such as probability estimation, were mostly reported without acknowledging their limitations. Results of this study suggest that more adequate prevention strategies for risky gambling should be developed for online poker.

    Sialosis (sialadenosis) is a term used to describe a disorder that involves both secretory and parenchymal changes of the major salivary glands, most commonly the parotid. Seen often in a dental office, it is recognized as an indolent, bilateral, non-inflammatory, non-neoplastic, soft, symmetrical, painless and persistent enlargement of the parotid glands. Four major entities have commonly been associated with this disorder. They are alcoholism, endocrinopathy (particularly diabetes mellitus), maLnutrition and idiopathic. We are reporting a case of alcoholic sialosis with its clinical and diagnostic aspects. It is important for the dental practitioner to recognize sialosis, because it often indicates the existence of an unsuspected systemic disease.

    PubMed Central

    Collier, Andrew; Watts, Maggie; Ghosh, Sujoy; Rice, Peter; Dewhurst, Neil

    2015-01-01

    Aims and Methods The UK’s Driver Vehicle Licensing Authority (DVLA) requires individuals to report if they have a medical condition such as alcohol dependence. General Medical Council guidance indicates that medical practitioners should ensure patients are aware of their impairment and requirement to notify the DVLA. Results In a survey of 246 people with known alcohol dependence, none were aware of advice on driving given by medical practitioners and none had self-reported. In addition, 362 doctors, either attending a college symposium or visiting a college website, were asked about their knowledge of DVLA regulations regarding alcohol dependence: 73% of those attending the symposium and 63% of those visiting the website answered incorrectly. In Scotland, over 20 000 people have alcohol dependence (over 1 million people with alcohol abuse), yet only 2548 people with alcohol problems self-reported to the DVLA in 2011. Clinical implications If the DVLA regulations were implemented, it could make an enormous difference to the behaviours of the driving public. PMID:26191423

    Allylic amination, directly from alcohols, has been demonstrated without any Lewis acid activators using an efficient and regiospecific molecular iron catalyst. Various amines and alcohols were employed and the reaction proceeded through the oxidation/reduction (redox) pathway. A direct one-step synthesis of common drugs, such as cinnarizine and nafetifine, was exhibited from cinnamyl alcohol that produced water as side product.

  2. How to evaluate the quality of health related websites.

    PubMed

    Gattoni, Filippo; Sicola, Chiara

    2005-03-01

    To establish reliable quality criteria for medical websites is of foremost importance in relation to the increasing number of Internet users, both health professionals and lay people, searching for medical information in the mass of these sites. Quality in general refers to a set of features that distinguish one person or thing from others of the same type. The quality of a website is usually related to its content and usability. The first criteria we considered are contents and readability, which must be targeted to the intended type of user. Other important criteria include: transparency, consistency, honesty, references to sources, accountability, respect of privacy, currency of content material, responsibility, and accessibility. Technical criteria are the use of consolidated and standard technologies, soft colours, short page download time. Good medical websites should also follow the suggestions of organizations such as the World Health Organization, the Food and Drug Administration, the European Communities. Another organization, Health On Net Foundation, has issued some guidelines for medical websites, summarized in eight points, fundamental to assign real scientific value to a site. We believe, in agreement with the literature, that it is unnecessary to apply strict rules to medical website developers. We want to stress the importance of guidelines and recommendations to be modified with the development of web technology and the cultural evolution of patient and physicians. In the near future the presence on the Internet of websites certified by national or international medical web authorities will lead users to trust and give their preference to such sites, leading to the self-regulation of website developers and users.

    2013-01-01

    Purpose Little is known about Veterans Service Organizations (VSOs) and their perspectives on veterans smoking or military tobacco control. Veterans have high smoking rates and many started smoking in the military, where a culture promoting use exists. Design We conducted a cross-sectional qualitative content analysis of VSO websites to classify health topics and identify tobacco-related information. Setting Websites were coded by trained raters from January-June of 2011. Data were entered, cleaned and analyzed from July 2011-January 2012. Participants 24 active VSO websites meeting inclusion criteria were rated independently. Method A comprehensive form was used to code 15 veteran-relevant health topics across multiple content areas/domains within the websites. Raters achieved 94.5% inter-rater agreement over nearly 5,000 data-points. Results A total of 277 health topics were addressed with the top five being Insurance/Tricare/VA issues (28.2%), PTSD (15.5%), disability/amputation/wounds (13.4%), Agent Orange (10.5%), and traumatic brain injury (TBI; 9.0%). Tobacco was mentioned four times (1.4%) across all 24 VSO websites and smoking cessation was never addressed. Conclusions VSO websites provide little information on tobacco-related topics and none offered information about smoking cessation. Given the high rates of tobacco use among veterans and active duty service members, and the interaction between smoking and PTSD symptoms and treatment outcomes, VSOs should consider making tobacco control and smoking cessation higher priority health issues on their websites.

    2012-09-01

    The Expectancy Challenge Alcohol Literacy Curriculum (ECALC) is a single session group-delivered program designed to modify alcohol expectancy processes and reduce alcohol use among children and young adults. The objective of this study was to demonstrate the effectiveness of the ECALC in reducing risky alcohol use among heavy drinking college men. Four fraternities at a large state university were randomly assigned to receive either the single session ECALC or a control presentation (2 fraternity houses per condition, n=250). Alcohol expectancies were assessed before and immediately after program presentation. Results demonstrated significant changes on 5 of the 7 subscales of the Comprehensive Effects of Alcohol Scale (CEOA) among students who received the ECALC when compared with control participants. Alcohol use data were collected for 4 weeks before and 4 weeks after program presentation. Compared with those in the control condition, students who received the ECALC demonstrated significant reductions in all facets of alcohol use measured, including decreased mean and peak blood alcohol content (BAC), decreased mean number of days drinking per week, decreased mean drinks per sitting, and decreased number of binge-drinking episodes per month. This study represents 2 important advances. First is the significant reduction in risky alcohol use produced by a single session group-delivered program. The second important advance is the success in changing expectancy processes without using impractical elements common in previous expectancy challenge methods (e.g., a "barlab" environment and actual alcohol administration).

    2016-07-01

    The purpose of this study was to conduct a systematic content analysis of sex tour websites to understand how sex tours are marketed to potential clients. A total of 380 web pages from 21 sex tour websites were reviewed. The sex tour websites sought to promote privacy and hassle-free travel with a local 'escort' and the opportunity for 'hooks-ups' with no strings attached. Three themes emerged around the description of sex workers: (1) enjoyment and complete acceptance, (2) a 'total girlfriend experience' and (3) exoticisation of the 'Third World' woman. The majority of the sex tourism websites used marketplace mythologies concerning racism, sexism and imperialism to appeal to sex tourists' desires for fantasy experiences, power and domination, and a renewed sense of identity. Legal and STI-related information was largely missing from the websites, and when it was included it was aimed at protecting sex tourists, not sex workers. It is of importance for researchers, social workers and others engaging with sex workers and sexscapes to recognise the power of language, cultural myths and framings and their ability to generate real-world social and health implications.

    2011-01-01

    Typical public and military-sponsored websites on stress and depression tend to be prescriptive. Some require users to complete lengthy questionnaires. Others reproduce printed flyers, papers, or educational materials not adapted for online use. Some websites require users to follow a prescribed path through the material. Stress Gym was developed as a first-level, evidence-based, website intervention to help U.S. military members learn how to manage mild to moderate stress and depressive symptoms using a self-help intervention with progress tracking and 24/7 availablility. It was designed using web-based, health-management intervention design elements that have been proven effective and users reported they prefer. These included interactivity, self-pacing, and pleasing aesthetics. Users learned how to manage stress by accessing modules they choose, and by practicing proven stress management strategies interactively immediately after login. Test results of Stress Gym with Navy members demonstrated that it was effective, with significant decreases in reported perceived stress levels from baseline to follow-up assessment. Stress Gym used design elements that may serve as a model for future websites to emulate and improve upon, and as a template against which to compare and contrast the design and functionality of future online, health-intervention websites.

  11. Design and Implementation of Website Information Disclosure Assessment System

    PubMed Central

    Cho, Ying-Chiang; Pan, Jen-Yi

    2015-01-01

    Internet application technologies, such as cloud computing and cloud storage, have increasingly changed people’s lives. Websites contain vast amounts of personal privacy information. In order to protect this information, network security technologies, such as database protection and data encryption, attract many researchers. The most serious problems concerning web vulnerability are e-mail address and network database leakages. These leakages have many causes. For example, malicious users can steal database contents, taking advantage of mistakes made by programmers and administrators. In order to mitigate this type of abuse, a website information disclosure assessment system is proposed in this study. This system utilizes a series of technologies, such as web crawler algorithms, SQL injection attack detection, and web vulnerability mining, to assess a website’s information disclosure. Thirty websites, randomly sampled from the top 50 world colleges, were used to collect leakage information. This testing showed the importance of increasing the security and privacy of website information for academic websites. PMID:25768434

  12. Analysis of Usage Patterns in Large Multimedia Websites

    NASA Astrophysics Data System (ADS)

    Singh, Rahul; Bhattarai, Bibek

    User behavior in a website is a critical indicator of the web site's usability and success. Therefore an understanding of usage patterns is essential to website design optimization. In this context, large multimedia websites pose a significant challenge for comprehension of the complex and diverse user behaviors they sustain. This is due to the complexity of analyzing and understanding user-data interactions in media-rich contexts. In this chapter we present a novel multi-perspective approach for usability analysis of large media rich websites. Our research combines multimedia web content analysis with elements of web-log analysis and visualization/visual mining of web usage metadata. Multimedia content analysis allows direct estimation of the information-cues presented to a user by the web content. Analysis of web logs and usage-metadata, such as location, type, and frequency of interactions provides a complimentary perspective on the site's usage. The entire set of information is leveraged through powerful visualization and interactive querying techniques to provide analysis of usage patterns, measure of design quality, as well as the ability to rapidly identify problems in the web-site design. Experiments on media rich sites including the SkyServer - a large multimedia web-based astronomy information repository demonstrate the efficacy and promise of the proposed approach.

    Alcohol, like mental health, is a neglected topic in public health discussions. However, it should be defined as a priority public health area because the evidence available to support this is very persuasive. Although only half the world's population drinks alcohol, it is the world's third leading cause of ill health and premature death, after low birth weight and unsafe sex, and the world's greatest cause of ill health and premature death among individuals between 25 and 59 years of age. This article aims to outline current global experiences with alcohol policies and suggests how to communicate better evidence-based policy responses to alcohol-related harm using narratives. The text summarizes 6 actions to provide incentives that would favor a healthier relationship with alcohol in contemporary society. Actions include price and availability changes, marketing regulations, changes in the format of drinking places and on the product itself, and actions designed to nudge people at the time of their purchasing decisions. Communicating alcohol narratives to policymakers more successfully will likely require a discourse emphasizing the reduction of heavy drinking occasions and the protection of others from someone else's problematic drinking.

    2013-01-01

    Background During the past few years, there has been an increasing recognition that Internet is playing a significant role in the synthesis, the distribution and the consumption of Novel Psychoactive Substances (NPS).The aim of this study was to assess the online availability of NPS in Persian language websites. Methods: The Google search engine was used to carry out an accurate qualitative assessment of information available on NPS in a sample of 104 websites. Results: The monitoring has led to the identification of 14 NPS including herbal, synthetic, pharmaceutical and combination drugs that have been sold online. Conclusion: The availability of online marketing of NPS in Persian language websites may constitute a public health challenge at least across three Farsi-speaking countries in the Middle East. Hence, descriptions of this phenomenon are valuable to clinicians and health professional in this region. Further international collaborative efforts may be able to tackle the growth and expansion of regular offer of NPS. PMID:23802109

  17. Do You Ignore Information Security in Your Journal Website?

    Dadkhah, Mehdi; Borchardt, Glenn; Lagzian, Mohammad

    2016-11-24

    Nowadays, web-based applications extend to all businesses due to their advantages and easy usability. The most important issue in web-based applications is security. Due to their advantages, most academic journals are now using these applications, with papers being submitted and published through their websites. As these websites are resources for knowledge, information security is primary for maintaining their integrity. In this opinion piece, we point out vulnerabilities in certain websites and introduce the potential for future threats. We intend to present how some journals are vulnerable and what will happen if a journal can be infected by attackers. This opinion is not a technical manual in information security, it is a short inspection that we did to improve the security of academic journals.

  18. The Effect of Brand on the Evaluation of Websites

    NASA Astrophysics Data System (ADS)

    de Angeli, Antonella; Hartmann, Jan; Sutcliffe, Alistair

    The effect of brand on consumer attitudes towards real and virtual goods is largely documented in consumer psychology and marketing. There is an obvious link between the design of a website and its brand. Yet, this effect has attracted little attention from the HCI community. This paper presents empirical evidence showing that brand attitude influences the evaluation of websites. The effect was reliable across different measures: people holding better attitudes were more positive in the evaluation of aesthetics, pleasure and usability. A sample of students (N=145) with a background in HCI was tested, suggesting that brand may influence the output of expert evaluators. The study provides support to the proposition of UX as a contextual-dependent response to the interaction with computing systems and has important implications for the design and evaluation of websites which are discussed in the conclusion.

  19. Student satisfaction with a Website designed for three nursing courses.

    PubMed

    Zwolski, K

    2000-01-01

    The website described was not designed to replace classroom teaching, but to serve as an additional tool for students attending a traditional course. Based on my experience and the data obtained from the evaluation questionnaire, the following points can be made: students are enthusiastic about the Internet and will access a web page that accompanies a particular course or courses a website can allow for objectives, not normally engendered by traditional methods, to be achieved. These may include, for instance, fostering a sense of community, providing new means of communication between professor and student and serving as a portal to the vast resources of the Internet. A single-theme website can effectively address the learning needs of students at different levels, in this case both undergraduate and graduate students A well-designed website can increase the visibility of the educational institution that sponsors it It is not easy to measure a website's effectiveness in helping students achieve traditional course objectives or its impact on student learning. The questionnaire results confirm students' satisfaction with the website and their belief that it was an important and useful learning tool. This is significant and positive. Future research is needed to measure the degree to which a website can increase learning in a particular area. The site required about 150 hours to construct and about 6-8 hours per week to maintain. This is a considerable amount of faculty time. Although I cannot speak for others, I firmly believe that this is a worthwhile investment. The website is clearly appreciated by students, and it seems logical to conclude that it is fulfilling some learning needs that may not be met by other methods. In addition, it provides the educator with a new vehicle for communication. It is exhilarating to create with new formats and to use expertise in a given area to reach students, foster community, and establish a presence beyond the classroom

  20. Website Service Quality in Ireland: An Empirical Study

    NASA Astrophysics Data System (ADS)

    Connolly, Regina

    Despite the fact that service quality is a critical determinant of website success, studies show that consumers frequently view the service quality delivered through websites as unsatisfactory. This paper outlines a study that investigated the dimensions of website service excellence valued by Irish customers of a small-to-medium enterprise specialising in gifts. The E-S-QUAL measurement instrument was applied to the customers who purchase products online from this retailer, in order to determine their purchasing patterns and the dimensions of e-service quality that they value. The results of this study indicate the effectiveness of the instrument in determining gaps in e-service quality. The findings will be of benefit both to practitioners and researchers seeking to improve their understanding of the factors that contribute towards the creation and maintenance of consumer satisfaction in Irish online transactions.

    We have investigated the gas-phase chemistry in dense cores where ice mantles containing ethanol and other alcohols have been evaporated. Model calculations show that methanol, ethanol, propanol, and butanol drive a chemistry leading to the formation of several large ethers and esters. Of these molecules, methyl ethyl ether (CH3OC2H5) and diethyl ether (C2H5)2O attain the highest abundances and should be present in detectable quantities within cores rich in ethanol and methanol. Gas-phase reactions act to destroy evaporated ethanol and a low observed abundance of gas-phase C,H,OH does not rule out a high solid-phase abundance. Grain surface formation mechanisms and other possible gas-phase reactions driven by alcohols are discussed, as are observing strategies for the detection of these large interstellar molecules.

    The NASA Langley Turbulence Model Resource (TMR) website has been active for over five years. Its main goal of providing a one-stop, easily accessible internet site for up-to-date information on Reynolds-averaged Navier-Stokes turbulence models remains unchanged. In particular, the site strives to provide an easy way for users to verify their own implementations of widely-used turbulence models, and to compare the results from different models for a variety of simple unit problems covering a range of flow physics. Some new features have been recently added to the website. This paper documents the site's features, including recent developments, future plans, and open questions.

    2017-03-09

    The aim of this study was to assess the scientific accuracy and the readability level of websites on kidney and bladder cancers. The search engines Google™, Yahoo™ and Bing™ were searched independently by assessors in November 2014 using the following keywords: "bladder cancer", "kidney cancer", "patient bladder cancer", "patient kidney cancer" and "bladder and kidney cancer". Only English-language websites were selected on the bases of predetermined inclusion and exclusion criteria. Assessors independently reviewed the findings and evaluated the accuracy and quality of each website by using the DISCERN and the LIDA instruments. The readability of the websites was calculated using the Flesch-Kincaid Grade Level Index and the Coleman-Liau Readability Index. Sixty-two websites were finally included in the study. The overall accuracy scores varied; for the DISCERN, the range was 28 to 76; out of 80 (mean ± SD, 47.1 ± 12.1; median = 46.0, interquartile range (IQR) = 19.2), and for the LIDA, the range was 52 to 125; out of 144 (mean ± SD, 101.9 ± 15.2; median, 103; IQR, 16.5). The creators of these websites were universities and research centres (n = 25, 40%), foundations and associations (n = 10, 16%), commercial and pharmaceutical companies (n = 13, 21%), charities and volunteer work (n = 4, 6%) and non-university educational bodies (n = 10, 16%). The readability scores (mean ± SD) were 11.2 ± 2.2 for the Flesch-Kincaid Grade Level Index and 11.2 ± 1.6 for the Coleman-Liau Readability Index. The accuracy and the quality of the websites on kidney and bladder cancers varied. In most websites, there were deficiencies in clarity of aims, presenting symptoms, investigations and treatment options. The readability matched grades 10-11 literacy levels-a level above the public readability level. The study highlights the needs for further improvement of the online information created for public and patients with kidney and bladder

  7. Trust in health information websites: A systematic literature review on the antecedents of trust.

    PubMed

    Kim, Yeolib

    2016-06-01

    Health websites are important sources of information for consumers. In choosing websites, trust in websites largely determines which website to access and how to best utilize the information. Thus, it is critical to understand why consumers trust certain websites and distrust others. A systematic literature review was conducted with the goal of identifying the antecedents of trust in health information websites. After four rounds of screening process, 20 articles between 2000 and 2013 were harvested. Factors that determine trust are classified into individual difference antecedents, website-related antecedents, and consumer-to-website interaction-related antecedents. The most frequently studied antecedents were socio-demographics, information quality, appearance, and perceived reputation of the website. Each antecedent of trust are discussed in detail and future research directions are proposed.

    Childhood obesity has reached epidemic proportions, and by 2012, more than one third of American children were overweight or obese. As a result, increasingly, children are developing complications of obesity including liver disease. In fact, non-alcoholic fatty liver disease is the most common form of chronic liver disease seen in children today. Recently, there has been a burgeoning literature examining the pathogenesis, genetic markers, and role of the microbiome in this disease. On the clinical front, new modalities of diagnosing hepatic steatosis and hepatic fibrosis are being developed to provide non-invasive methods of surveillance in children. Lastly, the mainstay of treatment of pediatric non-alcoholic fatty liver disease (NAFLD) has been largely through lifestyle interventions, namely, dieting and exercise. Currently, there are a number of clinical trials examining novel lifestyle and drug therapies for NAFLD that are registered with the US National Institutes of Health ClinicalTrials.gov website.

    Koo, Chulmo; Wati, Yulia; Park, Keeho

    2011-01-01

    Background The fact that patient satisfaction with primary care clinical practices and physician-patient communications has decreased gradually has brought a new opportunity to the online channel as a supplementary service to provide additional information. Objective In this study, our objectives were to examine the process of cognitive knowledge expectation-confirmation from eHealth users and to recommend the attributes of a “knowledge-intensive website.”. Knowledge expectation can be defined as users’ existing attitudes or beliefs regarding expected levels of knowledge they may gain by accessing the website. Knowledge confirmation is the extent to which user’s knowledge expectation of information systems use is realized during actual use. In our hypothesized research model, perceived information quality, presentation and attractiveness as well as knowledge expectation influence knowledge confirmation, which in turn influences perceived usefulness and end user satisfaction, which feeds back to knowledge expectation. Methods An empirical study was conducted at the National Cancer Center (NCC), Republic of Korea (South Korea), by evaluating its official website. A user survey was administered containing items to measure subjectively perceived website quality and expectation-confirmation attributes. A study sample of 198 usable responses was used for further analysis. We used the structural equation model to test the proposed research model. Results Knowledge expectation exhibited a positive effect on knowledge confirmation (beta = .27, P < .001). The paths from information quality, information presentation, and website attractiveness to knowledge confirmation were also positive and significant (beta = .24, P < .001; beta = .29, P < .001; beta = .18, P < .001, respectively). Moreover, the effect of knowledge confirmation on perceived usefulness was also positively significant (beta = .64, P < .001). Knowledge expectation together with knowledge confirmation

    2015-01-01

    Background Current concerns about vaccination resistance often cite the Internet as a source of vaccine controversy. Most academic studies of vaccine resistance online use quantitative methods to describe misinformation on vaccine-skeptical websites. Findings from these studies are useful for categorizing the generic features of these websites, but they do not provide insights into why these websites successfully persuade their viewers. To date, there have been few attempts to understand, qualitatively, the persuasive features of provaccine or vaccine-skeptical websites. Objective The purpose of this research was to examine the persuasive features of provaccine and vaccine-skeptical websites. The qualitative analysis was conducted to generate hypotheses concerning what features of these websites are persuasive to people seeking information about vaccination and vaccine-related practices. Methods This study employed a fully qualitative case study methodology that used the anthropological method of thick description to detail and carefully review the rhetorical features of 1 provaccine government website, 1 provaccine hospital website, 1 vaccine-skeptical information website focused on general vaccine safety, and 1 vaccine-skeptical website focused on a specific vaccine. The data gathered were organized into 5 domains: website ownership, visual and textual content, user experience, hyperlinking, and social interactivity. Results The study found that the 2 provaccine websites analyzed functioned as encyclopedias of vaccine information. Both of the websites had relatively small digital ecologies because they only linked to government websites or websites that endorsed vaccination and evidence-based medicine. Neither of these websites offered visitors interactive features or made extensive use of the affordances of Web 2.0. The study also found that the 2 vaccine-skeptical websites had larger digital ecologies because they linked to a variety of vaccine-related websites

    Argonne National Laboratory has completed the construction of a Website for the US Department of Energy (DOE) that provides detailed information on salt caverns and their use for disposing of nonhazardous oil field wastes (NOW) and naturally occurring radioactive materials (NORM). Specific topics in the Website include the following: descriptions of salt deposits and salt caverns within the US, salt cavern construction methods, potential types of wastes, waste emplacement, regulatory issues, costs, carcinogenic and noncarcinogenic human health risks associated with postulated cavern release scenarios, new information on cavern disposal (e.g., upcoming meetings, regulatory issues, etc.), other studies supported by the National Petroleum Technology Office (NPTO) (e.g., considerations of site location, cavern stability, development issues, and bedded salt characterization in the Midland Basin), and links to other associated Web sites. In addition, the Website allows downloadable access to reports prepared on the topic that were funded by DOE. Because of the large quantities of NOW and NORM wastes generated annually by the oil industry, information presented on this Website is particularly interesting and valuable to project managers, regulators, and concerned citizens.

    2011-06-01

    In the field of prevention, Internet websites and their related instruments constitute valuable tools for healthcare facilities, and particularly for Local Healthcare Authorities (LHA). As yet, however, their undoubted potential remains largely unexploited. Many LHA websites currently operating in Italy are organized in such a way that they fail to make adequate use of this precious resource. Indeed, communication regarding prevention is all too often limited to the simple reproduction of information and indications in a static and heterogeneous manner, so much so that it resembles a mere "online notice-board". The aim of the present research was to analyze the current situation and the various innovative proposals that have been made, in order to construct a more effective website model that could be used nationwide. To this end, the research was carried out through a two-pronged approach: on the one hand, all 190 LHA websites in Italy were analyzed; on the other, a questionnaire was administered to a sample of habitual users of the most modern and widespread social network, Facebook. Analysis and elaboration of the data gathered led to the creation of the model "@Prevention". This project is intended to introduce an innovative perspective into the field of online communication for healthcare prevention by providing a highly useful tool for the LHA, healthcare workers and, obviously, citizens.

    Background Pediatric dog bites are a significant public health problem worldwide. Existing prevention programs focused on altering children’s risky behavior with pet dogs tend to be atheoretical and only moderately effective. Objective Test efficacy of a website to train young children in relevant cognitive skills to be safe with pet dogs in their home. Setting Birmingham, Alabama, USA. Methods A randomized trial will be conducted with an expected sample of two groups of 34 children ages 4-6 (total N = 68). One group will engage in the newly-designed website at home for two weeks and the other group will engage in a control website on transportation safety for an equivalent amount of time. All participants will complete a battery of laboratory-based tests to assess safety with dogs and cognitive functioning both at baseline and post-intervention. Outcome Measures Primary analyses will be conducted through linear mixed models testing change over time. Children’s cognitive functioning, knowledge about safety with dogs, and behavior with dogs in simulation and in vivo will serve as the primary outcomes. Clinical Trial Registration This study is exempt from registry at the US government website, www.clinicaltrials.gov, based on being a behavioral trial in the early phases of testing. PMID:24871960

    Objective: The purpose of this study was to estimate the independent effects of increases in minimum alcohol prices and densities of private liquor stores on crime outcomes in British Columbia, Canada, during a partial privatization of off-premise liquor sales. Method: A time-series cross-sectional panel study was conducted using mixed model regression analysis to explore associations between minimum alcohol prices, densities of liquor outlets, and crime outcomes across 89 local health areas of British Columbia between 2002 and 2010. Archival data on minimum alcohol prices, per capita alcohol outlet densities, and ecological demographic characteristics were related to measures of crimes against persons, alcohol-related traffic violations, and non–alcohol-related traffic violations. Analyses were adjusted for temporal and regional autocorrelation. Results: A 10% increase in provincial minimum alcohol prices was associated with an 18.81% (95% CI: ±17.99%, p < .05) reduction in alcohol-related traffic violations, a 9.17% (95% CI: ±5.95%, p < .01) reduction in crimes against persons, and a 9.39% (95% CI: ±3.80%, p < .001) reduction in total rates of crime outcomes examined. There was no significant association between minimum alcohol prices and non–alcohol-related traffic violations (p > .05). Densities of private liquor stores were not significantly associated with alcohol-involved traffic violations or crimes against persons, though they were with non–alcohol-related traffic violations. Conclusions: Reductions in crime events associated with minimum-alcohol-price changes were more substantial and specific to alcohol-related events than the countervailing increases in densities of private liquor stores. The findings lend further support to the application of minimum alcohol prices for public health and safety objectives. PMID:26098040

  17. SUstaiNability: a science communication website on environmental research

    Environmental news mainly reach not specialist people by mass media, which generally focuses on fascinating or catastrophic events without reporting scientific data. Otherwise, scientific data on environment are published in peer-reviewed journals with specific language, so they could be not understandable to common people. In the last decade, Internet spread made easier to divulge environmental information. This allows everyone (scientist or not) to publish information without revision. In fact, World Wide Web includes many scientific sites with different levels of confidence. Within Italian scientific websites, there are those of University and Research Centre, but they mainly contain didactic and bureaucratic information, generally lacking in research news, or reporting them in peer-reviewed format. University and Research Centre should have an important role to divulge certified information, but news should be adapted to a general audience without scientific skills, in order to help population to gain knowledge on environmental issues and to develop responsible behavior. Therefore, an attractive website (www.sunability.unina2.it) has been created in order to divulge research products of Environmental, Biological and Pharmaceutical Sciences and Technologies Department (DiSTABiF) of Second University of Naples-SUN (Campania, Southern Italy). This website contains divulgation articles derived from peer-reviewed publications of DiSTABiF researchers and concerning studies on environmental, nutrition, and health issues, closely related topics. Environmental studies mainly referred to Caserta district (Southern Italy), where DiSTABiF is located. Divulgation articles have been shared by main social networks (Facebook: sunability, Twitter: @SUNability) and accesses have been monitored for 28 days in order to obtain demographic and geographic information about users and visualization number of both DiSTABiF website and social network pages.

    1998-02-16

    Furfural, 5-methylfurfural, and vanillin co-occurred in 64 barrel-aged red, white, and model wines with the reduction products, furfuryl alcohol, 5-methylfurfuryl alcohol, and vanillyl alcohol, and with the corresponding ethyl ethers of these alcohols. Hydrolytic studies in a model wine have shown that 5-methylfurfuryl ethyl ether is formed rapidly from 5-methylfurfuryl alcohol, but both decomposed quickly under the conditions. Vanillyl ethyl ether was also formed relatively rapidly, and both this ether and vanillyl alcohol were stable in the model wine. The formation of furfuryl ethyl ether from furfuryl alcohol and the subsequent decomposition of these two compounds were comparatively slow. The relative concentration of these aromatic alcohols and ethers in the barrel-aged wines was consistent with the observed stability of the furan derivatives, but low concentrations of vanillyl alcohol and vanillyl ethyl ether observed in all samples showed that factors other than solvolytic degradation were responsible for reducing the concentration of these compounds in wine. Furfuryl ethyl ether, which had an aroma threshold of 430 µg/L in a white wine, was found at approximate concentrations of up to 230 µg/L in the wines.

    2014-01-01

    Objective The goal of this study was to summarise the websites of electronic cigarette (e-cigarette) manufacturers in China and describe how they market their products. Methods From March to April 2013, we used two search keywords ‘electronic cigarette’ (Dian Zi Xiang Yan in Chinese) and ‘manufacturer’ (Sheng Chan Chang Jia in Chinese) to search e-cigarette manufacturers in China on Alibaba, an internet-based e-commerce business that covers business-to-business online marketplaces, retail and payment platforms, shopping search engine and data-centric cloud computing services. A total of 18 websites of 12 e-cigarette manufacturers in China were analysed by using a coding guide which includes 14 marketing claims. Results Health-related benefits were claimed most frequently (89%), followed by the claims of no secondhand smoke (SHS) exposure (78%), and utility for smoking cessation (67%). A wide variety of flavours, celebrity endorsements and e-cigarettes specifically for women were presented. None of the websites had any age restriction on access, references to government regulation or lawsuits. Instruction on how to use e-cigarettes was on 17% of the websites. Conclusions Better regulation of e-cigarette marketing messages on manufacturers’ websites is needed in China. The frequent claims of health benefits, smoking cessation, strategies appealing to youth and women are concerning, especially targeting women. Regulators should prohibit marketing claims of health benefits, no SHS exposure and value for smoking cessation in China until health-related, quality and safety issues have been adequately addressed. To avoid e-cigarette use for initiation to nicotine addiction, messages targeting youth and women should be prohibited. PMID:25335902

  6. [Medicine and driving: Alcohol and other toxins].

    PubMed

    Abramovici, Francis

    2015-10-01

    General practitioners and specialists, beyond their role of health care providers, have a societal responsibility regarding the use or misuse of alcohol, drugs including cannabis, and some medications. Alcohol remains the leading cause of road accidents, and more than 100,000 drivers were found to be driving while intoxicated in 2000. Other drugs are now systematically tested for in serious accidents. The various government and road safety websites as well as several significant studies on the subject show that drunk driving is still a major problem and that other drugs and medication are also a significant cause of accidents, either alone or in combination with alcohol. The role of psychiatric disorders sometimes complicates the risk. Doctors have an obligation to provide their patients with information and must have an accurate knowledge of relevant legislation. They may be liable for accidents caused by the driving of their patients. This liability requires them to be able to demonstrate that they gave the individual some information about insurance, the possible limitation of their driver's license, and the steps they should take should they misuse alcohol or other drugs, including some medications.

  7. Vaccine-criticism on the internet: new insights based on French-speaking websites.

    The internet is playing an increasingly important part in fueling vaccine related controversies and in generating vaccine hesitant behaviors. English language Antivaccination websites have been thoroughly analyzed, however, little is known of the arguments presented in other languages on the internet. This study presents three types of results: (1) Authors apply a time tested content analysis methodology to describe the information diffused by French language vaccine critical websites in comparison with English speaking websites. The contents of French language vaccine critical websites are very similar to those of English language websites except for the relative absence of moral and religious arguments. (2) Authors evaluate the likelihood that internet users will find those websites through vaccine-related queries on a variety of French-language versions of google. Queries on controversial vaccines generated many more vaccine critical websites than queries on vaccination in general. (3) Authors propose a typology of vaccine critical websites. Authors distinguish between (a) websites that criticize all vaccines ("antivaccine" websites) and websites that criticize only some vaccines ("vaccine-selective" websites), and between (b) websites that focus on vaccines ("vaccine-focused" websites) and those for which vaccines were only a secondary topic of interest ("generalist" websites). The differences in stances by groups and websites affect the likelihood that they will be believed and by whom. This study therefore helps understand the different information landscapes that may contribute to the variety of forms of vaccine hesitancy. Public authorities should have better awareness and understanding of these stances to bring appropriate answers to the different controversies about vaccination.

  8. Automated Assessment of the Quality of Depression Websites

    Tang, Thanh Tin; Hawking, David; Christensen, Helen

    2005-01-01

    Background Since health information on the World Wide Web is of variable quality, methods are needed to assist consumers to identify health websites containing evidence-based information. Manual assessment tools may assist consumers to evaluate the quality of sites. However, these tools are poorly validated and often impractical. There is a need to develop better consumer tools, and in particular to explore the potential of automated procedures for evaluating the quality of health information on the web. Objective This study (1) describes the development of an automated quality assessment procedure (AQA) designed to automatically rank depression websites according to their evidence-based quality; (2) evaluates the validity of the AQA relative to human rated evidence-based quality scores; and (3) compares the validity of Google PageRank and the AQA as indicators of evidence-based quality. Method The AQA was developed using a quality feedback technique and a set of training websites previously rated manually according to their concordance with statements in the Oxford University Centre for Evidence-Based Mental Health’s guidelines for treating depression. The validation phase involved 30 websites compiled from the DMOZ, Yahoo! and LookSmart Depression Directories by randomly selecting six sites from each of the Google PageRank bands of 0, 1-2, 3-4, 5-6 and 7-8. Evidence-based ratings from two independent raters (based on concordance with the Oxford guidelines) were then compared with scores derived from the automated AQA and Google algorithms. There was no overlap in the websites used in the training and validation phases of the study. Results The correlation between the AQA score and the evidence-based ratings was high and significant (r=0.85, P<.001). Addition of a quadratic component improved the fit, the combined linear and quadratic model explaining 82 percent of the variance. The correlation between Google PageRank and the evidence-based score was lower than

  9. Gasoline-aided production of alcohol and fuel

    SciTech Connect

    Roth, E.R.

    1984-04-10

    Gasoline aids production of alcohol and fuel in a solvent extraction and recovery process. Alcohol/water mixtures, such as those produced by fermentation of biomass material, are separated by extraction of alcohol with a solvent especially suited to such extraction and to subsequent removal. Conventional distillation steps to concentrate alcohol and eliminate water are rendered unnecessary at a considerable reduction in heat energy requirement (usually met with fossil fuel). Addition of gasoline between the solvent extraction and solvent recovery steps not only aids the latter separation but produces alcohol already denatured for fuel use.

    This year we implemented Teach Astronomy as a free online resource to be used as a teaching tool for non-science major astronomy courses and for a general audience interested in the subject. The comprehensive astronomy content of the website includes: an introductory text book, encyclopedia articles, images, two to three minute topical video clips, podcasts, and news articles. Teach Astronomy utilizes a novel technology to cluster, display, and navigate search results, called a Wikimap. We will present an overview of how Teach Astronomy works and how instructors can use it as an effective teaching tool in the classroom. Additionally, we will gather feedback from science instructors on how to improve the features and functionality of the website, as well as develop new assignment ideas using Teach Astronomy.

    2016-07-01

    Proper design has become a critical element needed to engage website and mobile application users. However, little research has been conducted to define the specific elements used in effective website and mobile application design. We attempt to review and consolidate research on effective design and to define a short list of elements frequently used in research. The design elements mentioned most frequently in the reviewed literature were navigation, graphical representation, organization, content utility, purpose, simplicity, and readability. We discuss how previous studies define and evaluate these seven elements. This review and the resulting short list of design elements may be used to help designers and researchers to operationalize best practices for facilitating and predicting user engagement.

  18. Surfing for history: websites featuring dental history object collections.

    2007-01-01

    Research is a key activity for any individual interested in dental history. It should come as no surprise that the ever-evolving Internet has become a major resource for those who seek the latest information available on this (or almost any other) subject. As a curator in a dental history museum, the author frequently checks other sources that feature dental objects while cataloging and identifying newly-acquired objects or those under consideration for exhibition. "Surfing" by computer is often the author's first activity in pursuing any research task. This paper is a tour of websites written in English that include historical dental objects. At the risk of stating the obvious, the author would like to point out that the accuracy and reliability of information on websites varies widely, depending on the source. Therefore, most of the sites listed here have been developed by institutions.

  19. Effects of Website Interactivity on Online Retail Shopping Behavior

    NASA Astrophysics Data System (ADS)

    Islam, Hafizul

    Motivations to engage in retail online shopping can include both utilitarian and hedonic shopping dimensions. To cater to these consumers, online retailers can create a cognitively and esthetically rich shopping environment, through sophisticated levels of interactive web utilities and features, offering not only utilitarian benefits and attributes but also providing hedonic benefits of enjoyment. Since the effect of interactive websites has proven to stimulate online consumer’s perceptions, this study presumes that websites with multimedia rich interactive utilities and features can influence online consumers’ shopping motivations and entice them to modify or even transform their original shopping predispositions by providing them with attractive and enhanced interactive features and controls, thus generating a positive attitude towards products and services offered by the retailer. This study seeks to explore the effects of Web interactivity on online consumer behavior through an attitudinal model of technology acceptance.

    2014-10-01

    The Internet often serves as a primary resource for individuals seeking health-related information, and a large and growing number of websites contain information related to developmental disabilities. This paper presents the results of an international evaluation of the characteristics and content of the top 10 ranked results (i.e., not including sponsored results - pay-per-click) returned when one of five terms related to developmental disabilities (i.e., ADHD, autism, down syndrome, learning disability, intellectual disability) was entered into one of six country specific Google online search engines (i.e., Australia (https://www.google.com.au), Canada (https://www.google.ca), Ireland (https://www.google.ie), New Zealand (https://www.google.co.nz), the United Kingdom (https://www.google.co.uk), and the United States (https://www.google.com)) on October 22, 2013. Collectively, we found that international consumers of websites related to developmental disabilities will encounter different websites with differing content and terminology, and should be critical consumers to ensure they locate the information they are seeking.

    2009-09-01

    This study assesses the availability of websites offering to sell psilocybin spores and psilocybin, a powerful hallucinogen contained in Psilocybe mushrooms. Over a 25-month period beginning in March 2003, eight searches were conducted in Google using the term "psilocybin spores." In each search the first 100 nonsponsored links obtained were scored by two independent raters according to standardized criteria to determine whether they offered to sell psilocybin or psilocybin spores. No attempts were made to procure the products offered for sale in order to ascertain whether the marketed psilocybin was in fact "genuine" or "counterfeit." Of the 800 links examined, 58% led to websites offering to sell psilocybin spores. Additionally, evidence that whole Psilocybe mushrooms are offered for sale online was obtained. Psilocybin and psilocybin spores were found to be widely available for sale over the Internet. Online purchase of psilocybin may facilitate illicit use of this potent psychoactive substance. Additional studies are needed to assess whether websites offering to sell psilocybin and psilocybin spores actually deliver their products as advertised.

  8. Measuring the readership of a health-related Website.

    PubMed

    Briggs, J S

    2000-01-01

    A national database of telemedicine was set up with the sponsorship of the British government to provide a source of information to anyone researching the field or proposing a telemedicine project. To monitor the readership of the database we subscribed to a free Internet service called Extreme Tracking. Since the Website was launched there have been over 9000 visits from over 5000 different Internet addresses. The peak was in the week after launch, when it had 400 visitors in four days. Subsequently, the number of visits tailed off slightly, but nine months later the database was still attracting about 800 visits per month. The majority of visits were via links from other Websites. Of the 288 different Websites identified, the one operated by the UK National Health Service (NHS) Information Authority generated the most visits, suggesting that many readers were from within the NHS. The second most common form of referral was from search engines. Most visits were on weekdays and during normal UK working hours. Taken together with the fact that the Internet domain that generated most visits was the '.uk' one, we concluded that most readers were based in the UK and accessed the site as part of their jobs rather than as a spare-time activity. This is encouraging for the take-up of telemedicine in the UK.

  9. Health websites in Italy: use, classification and international policy.

    PubMed

    Di Giacomo, Paola; Maceratini, Riccardo

    2002-09-01

    In this paper, we discuss international policy in relation to the use of health websites and we describe the results obtained from application of a search engine to the recognition and classification of health websites in Italy. We then compare the results with health websites in other countries. Effective use of technology has led to medical advances that have not only extended life expectancy, but also fuelled an increasingly well-informed public to expect more and more from today's healthcare providers. As a consequence of the Web's rapid, chaotic growth, the resulting network of information lacks organization and structure and the quest for a method of quickly finding relevant and reliable information is spawning the growth of Internet portal sites. The US and the European Union and now Italy, have established the importance of rules to check the quality of health sites both for the non-professional users (citizens), mainly for privacy and security (for example, of medical records); and for health operators (physicians and others), where the most important thing is to evaluate the quality of content. In June 2001, the search engine used here found 2627 Italian health sites, of which only 46 exhibited the HON Code, and they can be classified into: 1% personal medical sites, 17% health portals, 18%, metasites, 27% documental sites and 37% information sites for health operators and/or for citizens.

    2016-01-01

    Amateur meteor workers have always been interested to exchange information and experience. In the past this was only possible via personal contacts by letter or by specialized journals. With internet a much faster medium became available and plenty of websites, mailing lists, Facebook groups, etc., have been created in order to communicate about meteors. Today there is a wealth of meteor data circulating on internet, but the information is very scattered and not directly available to everyone. The authors have been considering how to organize an easy access to the many different meteor related publications. The best solution for the current needs of amateur meteor observers proved to be a dedicated website combined with a PDF journal, both being free available without any subscription fee or registration requirement. The authors decided to start with this project and in March 2016 the website meteornews.org has been created. A first issue of eMeteorNews was prepared in April 2016. The year 2016 will be a test period for this project.

    2003-08-01

    Consumers are faced with an ever-increasing array of blood pressure measuring devices, whether for use in clinical areas or for use by individuals anxious to measure their own blood pressure. Validation protocols that allow for independent evaluation of blood pressure measuring devices are available, and some of the devices on the market have been evaluated according to these protocols. The results of such evaluations have been published periodically in medical journals. However, such surveys are not readily available to the public and to health care authorities with responsibility for purchasing blood pressure measuring equipment for use in clinical medicine, and because of the necessarily lengthy publication process they are no longer up-to-date at the time of publication. Moreover, the results of published validation studies are often flawed because of protocol violations and the conclusions may not be valid. These considerations have been the stimulus for the establishment of an independent non-profit website, which will provide quarterly updates on the accuracy and performance of blood pressure measuring devices on the market as well as an expert assessment of the validation procedures on which recommendations are based. The ethos of the website is primarily educational and it is hoped that it will serve as a forum for the provision of much-needed information that will ultimately improve the management of hypertension. The website is due to be launched shortly and this paper outlines the general principles that have governed its establishment and the facilities that it will provide.

    The Navy Precision Optical Interferometer (NPOI) has been recording astronomical observations for nearly two decades, at this point with hundreds of thousands of individual observations recorded to date for a total data volume of many terabytes. To make maximum use of the NPOI data it is necessary to organize them in an easily searchable manner and be able to extract essential diagnostic information from the data to allow users to quickly gauge data quality and suitability for a specific science investigation. This sets the motivation for creating a comprehensive database of observation metadata as well as, at least, reduced data products. The NPOI database is implemented in MySQL using standard database tools and interfaces. The use of standard database tools allows us to focus on top-level database and interface implementation and take advantage of standard features such as backup, remote access, mirroring, and complex queries which would otherwise be time-consuming to implement. A website was created in order to give scientists a user friendly interface for searching the database. It allows the user to select various metadata to search for and also allows them to decide how and what results are displayed. This streamlines the searches, making it easier and quicker for scientists to find the information they are looking for. The website has multiple browser and device support. In this paper we present the design of the NPOI database and website, and give examples of its use.

    BACKGROUND AND OBJECTIVE Internet alcohol marketing is not well studied despite its prevalence and potential accessibility and attractiveness to youth. The objective was to examine longitudinal associations between self-reported engagement with Internet alcohol marketing and alcohol use transitions in youth. METHODS A US sample of 2012 youths aged 15 to 20 was surveyed in 2011. An Internet alcohol marketing receptivity score was developed, based on number of positive responses to seeing alcohol advertising on the Internet, visiting alcohol brand Web sites, being an online alcohol brand fan, and cued recall of alcohol brand home page images. We assessed the association between baseline marketing receptivity and both ever drinking and binge drinking (≥6 drinks per occasion) at 1-year follow-up with multiple logistic regression, controlling for baseline drinking status, Internet use, sociodemographics, personality characteristics, and peer or parent drinking. RESULTS At baseline, ever-drinking and binge-drinking prevalence was 55% and 27%, respectively. Many (59%) reported seeing Internet alcohol advertising, but few reported going to an alcohol Web site (6%) or being an online fan (3%). Higher Internet use, sensation seeking, having family or peers who drank, and past alcohol use were associated with Internet alcohol marketing receptivity, and a score of 1 or 2 was independently associated with greater adjusted odds of initiating binge drinking (odds ratio 1.77; 95% confidence interval, 1.13–2.78 and odds ratio 2.15; 95% confidence interval, 1.06–4.37 respectively) but not with initiation of ever drinking. CONCLUSIONS Although high levels of engagement with Internet alcohol marketing were uncommon, most underage youths reported seeing it, and we found a prospective association between receptivity to this type of alcohol marketing and future problem drinking, making additional research and ongoing surveillance important.

    2014-01-01

    Alcohol is widely consumed across the world in different cultural and social settings. Types of alcohol consumption differ between (a) light, only occasional consumption, (b) heavy chronic alcohol consumption, and (c) binge drinking as seen as a new pattern of alcohol consumption among teenagers and young adults. Heavy alcohol consumption is detrimental to many organs and tissues, including bones. Osteoporosis is regularly mentioned as a secondary consequence of alcoholism, and chronic alcohol abuse is established as an independent risk factor for osteoporosis. The review will present the different mechanisms and effects of alcohol intake on bone mass, bone metabolism, and bone strength, including alcoholism-related "life-style factors" such as malnutrition, lack of exercise, and hormonal changes as additional causative factors, which also contribute to the development of osteoporosis due to alcohol abuse.

    Online information seekers make heavy use of websites that accept their natural language questions. This study compared the three types of such websites: social question and answer (Q&A), digital reference services, and ask-an-expert services. Questions reflecting daily life, research, and crisis situations were posed to high use websites of all three types. The resulting answers' characteristics were analyzed in terms of speed, transparency, formality, and intimacy. The results indicate that social Q&A websites excel in speed, ask-an-expert websites in intimacy, and digital reference services in transparency and formality.

    2016-11-10

    Background The Internet has been reported to be the first informational resource for many fellowship applicants. The objective of this study was to assess the accessibility of orthopaedic foot and ankle fellowship websites and to evaluate the quality of information provided via program websites. Methods The American Orthopaedic Foot and Ankle Society (AOFAS) and the Fellowship and Residency Electronic Interactive Database (FREIDA) fellowship databases were accessed to generate a comprehensive list of orthopaedic foot and ankle fellowship programs. The databases were reviewed for links to fellowship program websites and compared with program websites accessed from a Google search. Accessible fellowship websites were then analyzed for the quality of recruitment and educational content pertinent to fellowship applicants. Results Forty-seven orthopaedic foot and ankle fellowship programs were identified. The AOFAS database featured direct links to 7 (15%) fellowship websites with the independent Google search yielding direct links to 29 (62%) websites. No direct website links were provided in the FREIDA database. Thirty-six accessible websites were analyzed for content. Program websites featured a mean 44% (range = 5% to 75%) of the total assessed content. The most commonly presented recruitment and educational content was a program description (94%) and description of fellow operative experience (83%), respectively. Conclusions There is substantial variability in the accessibility and quality of orthopaedic foot and ankle fellowship websites. Clinical Relevance Recognition of deficits in accessibility and content quality may assist foot and ankle fellowships in improving program information online.

  20. Kohonen Self-organizing Feature Maps as a Means to Benchmark College and University Websites

    2007-06-01

    Websites for colleges and universities have become the primary means for students to obtain information in the college search process. Consequently, institutions of higher education should target their websites toward prospective and current students' needs, interests, and tastes. Numerous parameters must be determined in creating a school website (e.g. number of links, page size, use of graphics, utilization of dynamic elements, and menuing options). This research details a decision support framework based upon Kohonen self-organizing feature maps to determine students' specific preferences for school websites. This research attempts to remove some of the subjectivity in designing a school website by finding the commonalities among websites that students find appealing and effective. Self-organizing feature maps are employed as a clustering method to compare the school's current website to other sites that students find both appealing and effective.

  1. Drive for muscularity and drive for thinness: the impact of pro-anorexia websites.

    Juarez, Lilia; Soto, Ernesto; Pritchard, Mary E

    2012-01-01

    In recent years, websites that stress the message of thinness as the ideal and only choice have surfaced on the internet. The possibility that pro-anorexia websites may reinforce restrictive eating and exercise behaviors is an area of concern. In addition, friends may be influencing one another to view these websites, further contributing to drive for thinness in women and drive for muscularity in men. Three hundred male and female undergraduate psychology students responded to questionnaires assessing: internalization of pro-anorexia website content, internalization of general media content, influence of friends to view pro-anorexia websites, peer influence, drive for muscularity, and drive for thinness. Results showed internalization of pro-anorexia website content was positively correlated with drive for thinness in women, and negatively correlated with drive for muscularity in men. Internalization of pro-anorexia website content was found to be related to both drive for thinness in women and drive for muscularity in men.

  2. Hand antiseptics: rubs versus scrubs, alcoholic solutions versus alcoholic gels.

    2001-08-01

    This report describes three different investigations undertaken to demonstrate the advantage of fluid alcoholic hand disinfectants. In the first study, the skin compatibility of Sterillium, a liquid alcoholic rub-in hand disinfectant was compared with that of Hibiscrub, a water-based handwashing antiseptic. Using various parameters such as image analysis of removed squames (D-squames), skin roughness or transepidermal water loss, Hibiscrub was found to be significantly inferior to Sterillium. Hibiscrub caused skin irritation in 15 volunteers who could not complete the test. In a second study, the microbicidal efficacy of Sterillium and Hibiscrub was tested in surgical hand disinfection. The microbial reduction by Sterillium was significantly greater than that of Hibiscrub, immediately after application as well as after the surgical procedure. In a third study, certain alcoholic gels were tested according to the EN 1500 'hygienic hand disinfection'. None of the gels tested passed the EN 1500 within 30s. However, Sterillium met the EN 1500 requirement within 30s. We conclude that Sterillium is superior to Hibiscrub in terms of skin tolerance and microbicidal efficacy in surgical hand disinfection. It is also superior to alcoholic gels.

    Given the uncertain effects of antidrug media campaigns, and the ease of finding online illegal drug information, research is needed on the Internet role in disseminating drug information to youths. This exploratory study analyzes National Survey of Parents and Youth (NSPY) data on drug website viewing among 12-18 year olds (N = 7,145). Approximately 10.4% reported drug-related website exposure: 5.4% viewed only websites that communicated how to avoid drugs or bad things about drugs (antidrug websites); 1.7% only viewed websites that communicated how to use drugs and good things about drugs (prodrug websites); and 3.2% viewed both types of websites. The low rates of viewing antidrug websites occurred despite efforts in the National Youth Antidrug Media Campaign (NYAMC) to encourage youths to visit such websites. Prodrug website viewers had used inhalants and been offered marijuana, perceived little risk in trying marijuana, intended to use marijuana, had close friends who used drugs, reported low parental monitoring, and had been exposed to antidrug media messages. Viewing antidrug websites was related to gender, income, likelihood of using marijuana in the next 12 months, having close friends who use drugs and talking to friends about avoiding drugs, parental monitoring, and drug prevention exposure. Prior prevention exposure increased drug website viewing overall, perhaps by increasing general curiosity about drugs. Because adolescents increasingly seek health information online, research is needed on how they use the Internet as a drug information source, the temporal relationships of prevention exposure and drug website viewing, and the effects of viewing prodrug websites on drug risk.

    Alcohol drinking habits and alcoholism are partly genetically determined. Alcohol is degraded primarily by alcohol dehydrogenase (ADH) wherein genetic variation that affects the rate of alcohol degradation is found in ADH1B and ADH1C. It is biologically plausible that these variations may be associated with alcohol drinking habits and alcoholism. By genotyping 9080 white men and women from the general population, we found that men and women with ADH1B slow vs fast alcohol degradation drank more alcohol and had a higher risk of everyday drinking, heavy drinking, excessive drinking and of alcoholism. For example, the weekly alcohol intake was 9.8 drinks (95% confidence interval (CI): 9.1-11) among men with the ADH1B.1/1 genotype compared to 7.5 drinks (95% CI: 6.4-8.7) among men with the ADH1B.1/2 genotype, and the odds ratio (OR) for heavy drinking was 3.1 (95% CI: 1.7-5.7) among men with the ADH1B.1/1 genotype compared to men with the ADH1B.1/2 genotype. Furthermore, individuals with ADH1C slow vs fast alcohol degradation had a higher risk of heavy and excessive drinking. For example, the OR for heavy drinking was 1.4 (95% CI: 1.1-1.8) among men with the ADH1C.1/2 genotype and 1.4 (95% CI: 1.0-1.9) among men with the ADH1B.2/2 genotype, compared with men with the ADH1C.1/1 genotype. Results for ADH1B and ADH1C genotypes among men and women were similar. Finally, because slow ADH1B alcohol degradation is found in more than 90% of the white population compared to less than 10% of East Asians, the population attributable risk of heavy drinking and alcoholism by ADH1B.1/1 genotype was 67 and 62% among the white population compared with 9 and 24% among the East Asian population.

    A brief overview of the reproductive capacities of both men and women in alcoholism is presented. A historical evaluation indicates a resurgence of interest in this area. The effect of chronic alcohol consumption on both male fertility and potency is reported in conjunction with alcohol-mediated effects on the female subject. Emphasis is placed on pharmacokinetics, metabolism and drinking behavior of the alcoholic female. The adverse actions of some therapeutic drugs and chronic alcohol consumption is discussed in relationship to fetal alcohol syndrome and the accompanied mental and somatic abnormalities.

    Alcoholism, a worldwide disorder, is the cause of a variety of neurologic disorders. In this article we discuss the cellular pathophysiology of ethanol addition and abuse as well as evidence supporting and refuting the role of inheritance in alcoholism. A genetic marker for alcoholism has not been identified, but neurophysiologic studies may be promising. Some neurologic disorders related to longterm alcoholism are due predominantly to inadequate nutrition (the thiamine deficiency that causes Wernicke's encephalopathy), but others appear to involve the neurotoxicity of ethanol on brain (alcohol withdrawal syndrome and dementia) and peripheral nerves (alcoholic neuropathy and myopathy).

  8. Assessment of function and clinical utility of alcohol and other drug web sites: An observational, qualitative study

    PubMed Central

    2011-01-01

    Background The increasing popularity and use of the internet makes it an attractive option for providing health information and treatment, including alcohol/other drug use. There is limited research examining how people identify and access information about alcohol or other drug (AOD) use online, or how they assess the usefulness of the information presented. This study examined the strategies that individuals used to identify and navigate a range of AOD websites, along with the attitudes concerning presentation and content. Methods Members of the general community in Brisbane and Roma (Queensland, Australia) were invited to participate in a 30-minute search of the internet for sites related to AOD use, followed by a focus group discussion. Fifty one subjects participated in the study across nine focus groups. Results Participants spent a maximum of 6.5 minutes on any one website, and less if the user was under 25 years of age. Time spent was as little as 2 minutes if the website was not the first accessed. Participants recommended that AOD-related websites should have an engaging home or index page, which quickly and accurately portrayed the site's objectives, and provided clear site navigation options. Website content should clearly match the title and description of the site that is used by internet search engines. Participants supported the development of a portal for AOD websites, suggesting that it would greatly facilitate access and navigation. Treatment programs delivered online were initially viewed with caution. This appeared to be due to limited understanding of what constituted online treatment, including its potential efficacy. Conclusions A range of recommendations arise from this study regarding the design and development of websites, particularly those related to AOD use. These include prudent use of text and information on any one webpage, the use of graphics and colours, and clear, uncluttered navigation options. Implications for future website

  9. Britain's alcohol market: how minimum alcohol prices could stop moderate drinkers subsidising those drinking at hazardous and harmful levels.

    PubMed

    Record, Chris; Day, Chris

    2009-10-01

    Discounting of alcoholic products is universal in U.K. supermarkets with some chains selling own brand spirits for less than the duty payable per item. Eighty per cent of alcohol purchases are made by 30% of the population and this group are the main beneficiaries. In December 2008 the government announced its intention to consult on modifications to the Licensing Act 2003 to enable the introduction of mandatory conditions for the sale of alcoholic products in order to curtail alcohol harm. In this article it is shown that families in Britain have nothing to fear from the introduction of a 50 p/unit minimum price of alcohol as the overall effect should be a reduction in average weekly supermarket bills for the majority while harmful and hazardous drinkers will pay more. By paying less for non-alcoholic products sold by supermarkets, moderate drinkers should no longer be effectively subsidising the alcohol purchased by the harmful and hazardous group.

    The objective of this study was to combine internationalization and localization of Websites and improvement of Website usability with user-centred design methods. This study designed for internationalization and localization of Websites for Asian users, and implemented usability engineering into every phase of Website usability testing, based on the internationalization and localization perspectives of the honeywell.com/your home Website. The first step was to develop the usage scenarios. Three Asian usability specialists carried out one heuristic evaluation session for the current honeywell.com/your home Website. The usability problems were analysed and possible solutions to these problems were discussed. In the next phase, cluster analysis was utilized to test current information architecture. The results provided options for future information architecture development for this Website. Finally, a performance measurement test was conducted to investigate the performance for Asian users. Based on the results, suggestions for improving the Website usability from the localization perspective were provided. The results demonstrate the user-centred design (UCD) approach and stress international and local issues in Website development to Website designers.

    Reynolds, Kristin A; Walker, John R; Walsh, Kate

    2015-10-01

    The goals of this study were to evaluate the quality of information concerning anxiety disorders in children that is available on the Internet and to evaluate changes in the quality of website information over time. The authors identified websites addressing child anxiety disorders (N = 26) using a Google search and recommendations from an expert in child anxiety. Each website was evaluated on the extent to which it addressed questions that parents consider important, the quality of information, and the reading level. All websites provided adequate information describing treatment options; however, fewer websites had information addressing many questions that are important to parents, including the duration of treatment, what happens when treatment stops, and the benefits and risks of various treatments. Many websites provided inadequate information on pharmacological treatment. Most websites were of moderate quality and had more difficult reading levels than is recommended. Five years after the initial assessment, authors re-analyzed the websites in order to investigate changes in content over time. The content of only six websites had been updated since the original analysis, the majority of which improved on the three aforementioned areas of evaluation. Websites could be strengthened by providing important information that would support parent decision-making.

    2010-06-01

    The purpose of this study was twofold: 1) to examine website content provided by U.S. and Canadian pediatric dentistry residency programs, and 2) to understand aspects of program websites that dental students report to be related to their interests. Sixty-eight program websites were reviewed by five interprofessional evaluators. A thirty-six-item evaluation form was organized into 1) program descriptive items listed on the American Academy of Pediatric Dentistry (AAPD) website (n=21); 2) additional program descriptive items not listed on the AAPD website but of interest (n=9); and 3) items related to website interface design (n=5). We also surveyed fifty-four dental students regarding their interest in various aspects of program descriptions. The results of this study suggest that pediatric dentistry residency programs in general tend to provide identical or less information than what is listed on the AAPD website. The majority of respondents (76 percent) reported that residency program websites would be their first source of information about advanced programs. The greatest gap between the available website information and students' interests exists in these areas: stipend and tuition information, state licensure, and program strengths. Pediatric dentistry residency programs underutilize websites as a marketing and recruitment tool and should incorporate more information in areas of students' priority interests.

    2012-12-01

    PhEDEx is the data-transfer management solution written by CMS. It consists of agents running at each site, a website for presentation of information, and a web-based data-service for scripted access to information. The website allows users to monitor the progress of data-transfers, the status of site agents and links between sites, and the overall status and behaviour of everything about PhEDEx. It also allows users to make and approve requests for data-transfers and for deletion of data. It is the main point-of-entry for all users wishing to interact with PhEDEx. For several years, the website has consisted of a single perl program with about 10K SLOC. This program has limited capabilities for exploring the data, with only coarse filtering capabilities and no context-sensitive awareness. Graphical information is presented as static images, generated on the server, with no interactivity. It is also not well connected to the rest of the PhEDEx codebase, since much of it was written before the data-service was developed. All this makes it hard to maintain and extend. We are re-implementing the website to address these issues. The UI is being rewritten in Javascript, replacing most of the server-side code. We are using the YUI toolkit to provide advanced features and context-sensitive interaction, and will adopt a Javascript charting library for generating graphical representations client-side. This relieves the server of much of its load, and automatically improves server-side security. The Javascript components can be re-used in many ways, allowing custom pages to be developed for specific uses. In particular, standalone test-cases using small numbers of components make it easier to debug the Javascript than it is to debug a large server program. Information about PhEDEx is accessed through the PhEDEx data-service, since direct SQL is not available from the clients’ browser. This provides consistent semantics with other, externally written monitoring tools, which

    Astronomy Picture of the Day (APOD) images may start on the apod.nasa.gov website, but their reach goes much further than the individual sitting at their computer screen. They provoke questions that then prompts the reader to email the authors; teachers use the images in their classrooms; students use them in their projects. This presentation will take a look at some of the work done using APOD images and text, including public outreach via middle school presentations and email communications, and academic uses beyond astronomy such as lesson plans on atmospheric refraction and even plagiarism, copyright and fair use.

    Rapid analysis of satellite observations of the state of the atmosphere and the contaminant levels within it can be used for pollution monitoring, forest fire detection and volcanic activity monitoring. There are numerous operational satellite instruments for which this is possible. The IASI instruments, currently flying on board the MetOp-A and MetOp-B satellite platforms, are used to produce Near Real Time (NRT) data using analysis algorithms developed by Oxford University. The data is then displayed on a website within 3 hours of measurement. This allows for the semi-continuous monitoring of the state of the atmosphere over most of the globe, both in daylight and at night. Global coverage is achieved 4 times per day, which is a significant advantage over most of the alternatives, either geostationary, giving limited spatial coverage, or UV instruments which are only able to observe during the daylight side of the orbit. The website includes flags for atmospheric contaminants detectable by IASI, including dust, biomass burning-derived species and volcanic ash and SO2. In the near future, the website will be developed to also include a quantitative estimate of the mass loading of SO2 contained within any volcanic cloud. Emissions of volcanic products, such as ash and SO2, are useful indicators of a change in the activity level of a volcano. Since many volcanoes are only monitored by remote sensing methods, such as satellite instruments, this can be the only such indicator available. These emissions are also dangerous to passing aircraft, causing damage to external surfaces of the plane and to the engines, sometimes leading to failure. Evacuation of regions surrounding volcanoes, and cessation or diversion of air traffic around actively erupting volcanoes is costly and highly disruptive but is sometimes required. Up to date information is of critical importance as to when to make these sensitive decisions. An archive of data will be available to allow for easy

    Prenatal exposure to alcohol can damage the developing fetus and is the leading preventable cause of birth defects and intellectual and neurodevelopmental disabilities. In 1973, fetal alcohol syndrome was first described as a specific cluster of birth defects resulting from alcohol exposure in utero. Subsequently, research unequivocally revealed that prenatal alcohol exposure causes a broad range of adverse developmental effects. Fetal alcohol spectrum disorder (FASD) is the general term that encompasses the range of adverse effects associated with prenatal alcohol exposure. The diagnostic criteria for fetal alcohol syndrome are specific, and comprehensive efforts are ongoing to establish definitive criteria for diagnosing the other FASDs. A large and growing body of research has led to evidence-based FASD education of professionals and the public, broader prevention initiatives, and recommended treatment approaches based on the following premises:▪ Alcohol-related birth defects and developmental disabilities are completely preventable when pregnant women abstain from alcohol use.▪ Neurocognitive and behavioral problems resulting from prenatal alcohol exposure are lifelong.▪ Early recognition, diagnosis, and therapy for any condition along the FASD continuum can result in improved outcomes.▪ During pregnancy:◦no amount of alcohol intake should be considered safe;◦there is no safe trimester to drink alcohol;◦all forms of alcohol, such as beer, wine, and liquor, pose similar risk; and◦binge drinking poses dose-related risk to the developing fetus.

    Three drugs are currently marketed in France in the prevention of relapse in alcohol-dependent patients. Their efficacy though real remains limited and it is useful to develop other molecules. Some products are at present under evaluation, and are already or could be used in the near future in the treatment of alcohol dependence: baclofene, oxybate de sodium (GHB), nalmefene, topiramate, ondansetron and aripiprazole. The available studies on these molecules are still limited and the results sometimes clinically modest. Nevertheless, some of them open interesting future prospects. If there is no big revolution to wait in the short term in the treatment of alcohol dependence, we can consider some interesting orientations: better effectiveness on alcohol consumption, but also change of paradigm concerning the objectives and the methods of this treatment: reduction of consumption versus abstinence, treatment on request, choice of the molecule guided by objective criteria (psychosocial, biological, genetic...).

    The detrimental effects of prenatal alcohol exposure on the developing brain include structural brain anomalies as well as cognitive and behavioral deficits. Initial neuroimaging studies of fetal alcohol spectrum disorders (FASD) using magnetic resonance imaging (MRI) confirmed previous autopsy reports of overall reduction in brain volume and central nervous system (CNS) disorganization, with specific structural abnormalities of the corpus callosum, cerebellum, caudate, and hippocampus. Advances in neuroimaging techniques have allowed detection of regional increases in cortical thickness and gray matter volume along with decreased volume and disorganization of white matter in individuals with FASD. In addition, functional imaging studies have found functional and neurochemical differences in those prenatally exposed to alcohol. Behavioral alterations noted in individuals with FASD are consistent with the findings noted in the brain imaging studies. Continued neuroimaging studies are needed to further advance understanding of the neuroteratogenic effects of alcohol. PMID:19731391

    Human studies are necessary to identify and classify the brain systems predisposing individuals to develop alcohol use disorders and those modified by alcohol, while animal models of alcoholism are essential for a mechanistic understanding of how chronic voluntary alcohol consumption becomes compulsive, how brain systems become damaged, and how damage resolves. Our current knowledge of the neuroscience of alcohol dependence has evolved from the interchange of information gathered from both human alcoholics and animal models of alcoholism. Together, studies in humans and animal models have provided support for the involvement of specific brain structures over the course of alcohol addiction, including the prefrontal cortex, basal ganglia, cerebellum, amygdala, hippocampus, and the hypothalamic–pituitary–adrenal axis.

    Background Medication is the most common intervention in health care, and written medication information can affect consumers’ medication-related behavior. Research has shown that a large proportion of Australians search for medication information on the Internet. Objective To evaluate the medication information content, based on consumer medication information needs, and usability of 4 Australian health websites: Better Health Channel, myDr, healthdirect, and NPS MedicineWise . Methods To assess website content, the most common consumer medication information needs were identified using (1) medication queries to the healthdirect helpline (a telephone helpline available across most of Australia) and (2) the most frequently used medications in Australia. The most frequently used medications were extracted from Australian government statistics on use of subsidized medicines in the community and the National Census of Medicines Use. Each website was assessed to determine whether it covered or partially covered information and advice about these medications. To assess website usability, 16 consumers participated in user testing wherein they were required to locate 2 pieces of medication information on each website. Brief semistructured interviews were also conducted with participants to gauge their opinions of the websites. Results Information on prescription medication was more comprehensively covered on all websites (3 of 4 websites covered 100% of information) than nonprescription medication (websites covered 0%-67% of information). Most websites relied on consumer medicines information leaflets to convey prescription medication information to consumers. Information about prescription medication classes was less comprehensive, with no website providing all information examined about antibiotics and antidepressants. Participants (n=16) were able to locate medication information on websites in most cases (accuracy ranged from 84% to 91%). However, a number of

    Consumer on-line behaviors are more important than ever due to highly growth of on-line shopping. The purposes of this study were to design placement methods of background music for shopping website and examine the effect on browsers' emotional and cognitive response. Three placement points of background music during the browsing, i.e. 2 min., 4 min., and 6 min. from the start of browsing were considered for entry points. Both browsing without music (no music) and browsing with constant music volume (full music) were treated as control groups. Participants' emotional state, approach-avoidance behavior intention, and action to adjust music volume were collected. Results showed that participants had a higher level of pleasure, arousal and approach behavior intention for the three placement points than for no music and full music. Most of the participants for full music (5/6) adjusted the background music. Only 16.7% (3/18) participants for other levels turn off the background music. The results indicate that playing background music after the start of browsing is benefit for on-line shopping atmosphere. It is inappropriate to place background music at the start of browsing shopping website. The marketer must manipulated placement methods of background music for a web store carefully.

    Despite the fact that Malaysian public institutions have progressed considerably on website and portal usage, web accessibility has been reported as one of the issues deserves special attention. Consistent with the government moves to promote an effective use of web and portal, it is essential for the government institutions to ensure compliance with established standards and guidelines on web accessibility. This paper evaluates accessibility of 25 Malaysian ministries websites using automated tools i.e. WAVE and Achecker. Both tools are designed to objectively evaluate web accessibility in conformance with Web Content Accessibility Guidelines 2.0 (WCAG 2.0) and United States Rehabilitation Act 1973 (Section 508). The findings reported somewhat low compliance to web accessibility standard amongst the ministries. Further enhancement is needed in the aspect of input elements such as label and checkbox to be associated with text as well as image-related elements. This findings could be used as a mechanism for webmasters to locate and rectify errors pertaining to the web accessibility and to ensure equal access of the web information and services to all citizen.

  16. A health literacy assessment of the epilepsy.com website.

    Current healthcare guidelines identify low health literacy as a major barrier to optimal health communication. Health literacy is defined as the degree to which individuals can obtain, process and understand basic health information and services needed to make appropriate health decisions. An estimated 90 million people in the U.S. have marginal health literacy. The Institute of Medicine and the U.S. Department of Education recommend that health related information be written at the 6th-8th grade level to address low health literacy. Epidemiological studies demonstrate that persons with epilepsy have significantly lower educational attainment and lower incomes placing them at risk for low health literacy and limited Internet access. While Internet users tend to have higher educational attainment, previous research indicates even good readers prefer simpler rather than more complex medical information. Health educational content that could be printed and given to patients addresses an important need in clinical epilepsy care. Previous reviews of health websites found they exceed recommended readability levels. Two online programs were used to assess the reading level of 1327 web pages on the www.epilepsy.com website using established readability formulas. Based on the Flesch Reading Ease assessment, only 3% of epilepsy.com web pages are written for a 6th grade reading level or below. If 8th grade level or below is used as the standard, only 15% are adequate. Recommendations and examples are provided for improving the readability of epilepsy-specific health education content.

    The FAST application was designed to replace the paper and pen method of checking out and checking in GSA Vehicles at KSC. By innovating from a paper and pen based checkout system to a fully digital one, not only the resources wasted by printing the checkout forms have been reduced, but it also reduces significantly the time that users and fleet managers need to interact with the system as well as improving the record accuracy for each vehicle. The vehicle information is pulled from a centralized database server in the SPSDL. In an attempt to add a new feature to the FAST application, the author of this report (alongside the FAST developers) has been designing and developing the FAST Management Website. The GSA fleet managers had to rely on the FAST developers in order to add new vehicles, edit vehicles and previous transactions, or for generating vehicles reports. By providing an easy-to-use FAST Management Website portal, the GSA fleet managers are now able to easily move vehicles, edit records, and print reports.

    2012-01-01

    Although job seekers' motivation to process the information encountered during recruitment partially influences recruitment success, little is known about what motivates more thorough information processing. To address this issue, we integrated recruitment and social information processing theories to examine the possibility that diversity cues on recruitment websites influence website viewers' processing of presented information. Utilizing a controlled experiment and a hypothetical organization, Study 1 revealed that both Blacks and Whites spent more time viewing recruitment websites and better recalled website information when the sites included racial diversity cues. These relationships were stronger for Blacks, and organizational attractiveness perceptions mediated these effects for Blacks but not for Whites. Study 2 found similar relationships for Black and White participants viewing real organizational recruitment websites after taking into account perceived organizational attributes and website design effects. Implications of these findings for recruiting organizations are discussed.

    2014-01-01

    Society has had an interest in controlling the production, distribution, and use of alcohol for millennia. The use of alcohol has always had consequences, be they positive or negative, and the role of government in the regulation of alcohol is now universal. This is accomplished at several levels, first through controls on production, importation, distribution, and use of alcoholic beverages, and second, through criminal laws, the aim of which is to address the behavior of users themselves. A number of interventions and policies reduce alcohol-related consequences to society by regulating alcohol pricing, targeting alcohol-impaired driving, and limiting alcohol availability. The legal system defines criminal responsibility in the context of alcohol use, as an enormous percentage of violent crime and motor death is associated with alcohol intoxication. In recent years, recovery-oriented policies have aimed to expand social supports for recovery and to improve access to treatment for substance use disorders within the criminal justice system. The Affordable Care Act, also know as "ObamaCare," made substantial changes to access to substance abuse treatment by mandating that health insurance include services for substance use disorders comparable to coverage for medical and surgical treatments. Rather than a simplified "war on drugs" approach, there appears to be an increasing emphasis on evidence-based policy development that approaches alcohol use disorders with hope for treatment and prevention. This chapter focuses on alcohol and the law in the United States.

  9. Kinetic and mechanistic studies of methylated liver alcohol dehydrogenase.

    PubMed Central

    Tsai, C S

    1978-01-01

    Reductive methylation of lysine residues activates liver alcohol dehydrogenase in the oxidation of primary alcohols, but decreases the activity of the enzyme towards secondary alcohols. The modification also desensitizes the dehydrogenase to substrate inhibition at high alcohol concentrations. Steady-state kinetic studies of methylated liver alcohol dehydrogenase over a wide range of alcohol concentrations suggest that alcohol oxidation proceeds via a random addition of coenzyme and substrate with a pathway for the formation of the productive enzyme-NADH-alcohol complex. To facilitate the analyses of the effects of methylation on liver alcohol dehydrogenase and factors affecting them, new operational kinetic parameters to describe the results at high substrate concentration were introduced. The changes in the dehydrogenase activity on alkylation were found to be associated with changes in the maximum velocities that are affected by the hydrophobicity of alkyl groups introduced at lysine residues. The desensitization of alkylated liver alcohol dehydrogenase to substrate inhibition is identified with a decrease in inhibitory Michaelis constants for alcohols and this is favoured by the steric effects of substituents at the lysine residues.

    The internet offers an accessible and cost-effective way to help women suffering with various types of postnatal mental illness and also can provide resources for healthcare professionals. Many websites on postnatal mental illness are available, but there is little information on the range or quality of information and resources offered. The current study therefore aimed to review postnatal health websites and evaluate their quality on a variety of dimensions. A systematic review of postnatal health websites was conducted. Searches were carried out on four search engines (Google, Yahoo, Ask Jeeves and Bing) which are used by 98% of web users. The first 25 websites found for each key word and their hyperlinks were assessed for inclusion in the review. Websites had to be exclusively dedicated to postnatal mental health or have substantial information on postnatal mental illness. Eligible websites (n=114) were evaluated for accuracy of information, available resources and quality. Results showed that information was largely incomplete and difficult to read; available help was limited and website quality was variable. The top five postnatal mental illness websites were identified for (1) postnatal mental illness sufferers and (2) healthcare professionals. It is hoped these top websites can be used by healthcare professionals both for their own information and to advise patients on quality online resources.

    2011-07-01

    According to dual-process models, excessive alcohol use emerges when response inhibition ability is insufficient to inhibit automatic impulses to drink alcohol. This study examined whether strengthening response inhibition for alcohol-related cues decreases alcohol intake. Fifty-two heavy drinking students were randomly assigned to one of two conditions: In the beer/no-go condition, participants performed a go/no-go task that consistently paired alcohol-related stimuli with a stopping response, to increase response inhibition for alcohol-related stimuli. In the beer/go condition, in contrast, participants were always required to respond to alcohol-related stimuli during the go/no-go task. Before and after the go/no-go manipulation, we measured weekly alcohol intake and implicit attitudes toward alcohol. In addition, we measured alcohol consumption during a taste test immediately after the go/no-go manipulation. Following the manipulation, participants in the beer/no-go condition demonstrated significantly increased negative implicit attitudes toward alcohol, and a significant reduction in weekly alcohol intake, while participants in the beer/go condition showed a non-significant increase in implicit positive attitudes toward alcohol and a significant increase in weekly alcohol intake. This study demonstrates that repeatedly stopping prepotent responses toward alcohol-related stimuli can be an effective strategy to reduce excessive alcohol use.

    Edenberg, Howard J; Foroud, Tatiana

    2013-08-01

    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.

    Alcohol abuse is a significant contributor to the global burden of disease and can lead to tissue damage and organ dysfunction in a subset of alcoholics. However, a subset of alcoholics without any of these predisposing factors can develop alcohol-mediated organ injury. The gastrointestinal tract (GI) could be an important source of inflammation in alcohol-mediated organ damage. The purpose of review was to evaluate mechanisms of alcohol-induced endotoxemia (including dysbiosis and gut leakiness), and highlight the predisposing factors for alcohol-induced dysbiosis and gut leakiness to endotoxins. Barriers, including immunologic, physical, and biochemical can regulate the passage of toxins into the portal and systemic circulation. In addition, a host of environmental interactions including those influenced by circadian rhythms can impact alcohol-induced organ pathology. There appears to be a role for therapeutic measures to mitigate alcohol-induced organ damage by normalizing intestinal dysbiosis and/or improving intestinal barrier integrity. Ultimately, the inflammatory process that drives progression into organ damage from alcohol appears to be multifactorial. Understanding the role of the intestine in the pathogenesis of alcoholic liver disease can pose further avenues for pathogenic and treatment approaches. PMID:26501334

    2008-03-01

    It is of no coincidence that a number of recent Harm Reduction Digests have addressed the issue of the reduction of alcohol-related harm. Despite the dominant focus on illicit drug use in the popular discourse, alcohol remains Australia's number one drug problem, as it is in many other developed countries. In this Digest Munro and de Wever use the 'four Ps' of marketing: product, price, place and promotion, to critique the two decades industry self-regulation of alcohol marketing. They conclude that if we are going to develop policies which effectively change Australian drinking culture to reduce alcohol-related harm, we need first to accept that the alcohol industry and the health field have separate and conflicting interests.

In addition, a literature search in the discussed area was performed. Strong clinical and experimental evidence lead to recognition of the key toxic role of alcohol in the pathogenesis of ALD. The liver biopsy can confirm the etiology of NASH or alcoholic steatohepatitis (ASH) and assess structural alterations of cells, their organelles, as well as inflammatory activity. Three histological stages of ALD are simple steatosis, ASH, and chronic hepatitis with hepatic fibrosis or cirrhosis. These latter stages may also be associated with a number of cellular and histological changes, including the presence of Mallory's hyaline, megamitochondria, or perivenular and perisinusoidal fibrosis. Genetic polymorphisms of ethanol metabolizing enzymes such as cytochrome p450 (CYP) 2E1 activation may change the severity of ASH and NASH. Alcohol mediated hepatocarcinogenesis, immune response to alcohol in ASH, as well as the role of other risk factors such as its comorbidities with chronic viral hepatitis in the presence or absence of human deficiency virus are discussed. Dysregulation of hepatic methylation, as result of ethanol exposure, in hepatocytes transfected with hepatitis C virus (HCV), illustrates an impaired interferon signaling. The hepatotoxic effects of ethanol undermine the contribution of malnutrition to the liver injury. Dietary interventions such as micro and macronutrients, as well as changes to the microbiota are suggested. The clinical aspects of NASH, as part of metabolic syndrome in the aging population, are offered. The integrative symposia investigate different aspects of alcohol-induced liver damage and possible

  20. Alcohol disrupts sleep homeostasis.

    Alcohol is a potent somnogen and one of the most commonly used "over the counter" sleep aids. In healthy non-alcoholics, acute alcohol decreases sleep latency, consolidates and increases the quality (delta power) and quantity of NREM sleep during the first half of the night. However, sleep is disrupted during the second half. Alcoholics, both during drinking periods and during abstinences, suffer from a multitude of sleep disruptions manifested by profound insomnia, excessive daytime sleepiness, and altered sleep architecture. Furthermore, subjective and objective indicators of sleep disturbances are predictors of relapse. Finally, within the USA, it is estimated that societal costs of alcohol-related sleep disorders exceeds $18 billion. Thus, although alcohol-associated sleep problems have significant economic and clinical consequences, very little is known about how and where alcohol acts to affect sleep. In this review, we have described our attempts to unravel the mechanism of alcohol-induced sleep disruptions. We have conducted a series of experiments using two different species, rats and mice, as animal models. We performed microdialysis, immunohistochemical, pharmacological, sleep deprivation and lesion studies which suggest that the sleep-promoting effects of alcohol may be mediated via alcohol's action on the mediators of sleep homeostasis: adenosine (AD) and the wake-promoting cholinergic neurons of the basal forebrain (BF). Alcohol, via its action on AD uptake, increases extracellular AD resulting in the inhibition of BF wake-promoting neurons. Since binge alcohol consumption is a highly prevalent pattern of alcohol consumption and disrupts sleep, we examined the effects of binge drinking on sleep-wakefulness. Our results suggest that disrupted sleep homeostasis may be the primary cause of sleep disruption observed following binge drinking. Finally, we have also shown that sleep disruptions observed during acute withdrawal, are caused due to impaired

    There are not many studies exploring the association between alcohol use and risky sexual behaviors among migrant workers. This study analyzed how changes in alcohol use was associated with changes in risky sexual behavior and psychosocial variables. Data for this study was drawn from an HIV risk reduction project. Repeated measures ANOVA and Linear mixed model statistical method was conducted to find changes and association between alcohol use, sexual risk and psychosocial variables over time. The sample (n = 203) was composed of African Americans (33.0 %) and Hispanics (77.0 %) men. Both groups, over time, showed reduction in sexual risk in accordance with reduction in alcohol use. Changes in alcohol use and psychosocial variables showed significant association with sexual risk changes over time. Psychological strategies like building social support should be considered for HIV risk reduction intervention directed towards high alcohol consuming migrant workers.

    Background Internet websites and smartphone apps have become a popular resource to guide parents in their children’s feeding and nutrition. Given the diverse range of websites and apps on infant feeding, the quality of information in these resources should be assessed to identify whether consumers have access to credible and reliable information. Objective This systematic analysis provides perspectives on the information available about infant feeding on websites and smartphone apps. Methods A systematic analysis was conducted to assess the quality, comprehensibility, suitability, and readability of websites and apps on infant feeding using a developed tool. Google and Bing were used to search for websites from Australia, while the App Store for iOS and Google Play for Android were used to search for apps. Specified key words including baby feeding, breast feeding, formula feeding and introducing solids were used to assess websites and apps addressing feeding advice. Criteria for assessing the accuracy of the content were developed using the Australian Infant Feeding Guidelines. Results A total of 600 websites and 2884 apps were screened, and 44 websites and 46 apps met the selection criteria and were analyzed. Most of the websites (26/44) and apps (43/46) were noncommercial, some websites (10/44) and 1 app were commercial and there were 8 government websites; 2 apps had university endorsement. The majority of the websites and apps were rated poor quality. There were two websites that had 100% coverage of information compared to those rated as fair or poor that had low coverage. Two-thirds of the websites (65%) and almost half of the apps (47%) had a readability level above the 8th grade level. Conclusions The findings of this unique analysis highlight the potential for website and app developers to merge user requirements with evidence-based content to ensure that information on infant feeding is of high quality. There are currently no apps available to

  3. Spirituality and alcoholics anonymous.

    PubMed

    Tonigan, J Scott

    2007-04-01

    What can be confidently said about AA in general and about the role of spirituality in AA in particular? First, there is convincing evidence that alcoholism severity predicts later AA attendance. Second, atheists are less likely to attend AA, relative to individuals who already hold spiritual and/or religious beliefs. However, belief in God before AA attendance does not offer any advantage in AA-related benefits, and atheists, once involved, are at no apparent disadvantage in deriving AA-related benefits. Third, the spiritually-based principles of AA appear to be endorsed in AA meetings regardless of the perceived social dynamics or climate of a particular meeting, eg, highly cohesive or aggressive. Fourth, significant increases in spiritual and religious beliefs and practices seem to occur among AA-exposed individuals. Fifth, in spite of much discussion to the contrary there is little evidence that spirituality directly accounts for later abstinence. We are finding, however, that spirituality has an important indirect effect in predicting later drinking reductions. Specifically, in the past 20 years a number of effective methods have been developed to facilitate initial AA attendance (AA dropout is high, with some estimates ranging as high as 80%). Interventions that lead to initial increases in spirituality appear to lead to sustained AA affiliation, which, in turn, produces sustained recovery over time.

  4. Alcohol liver disease: A review of current therapeutic approaches to achieve long-term abstinence

    2015-01-01

    Harmful alcohol drinking may lead to significant damage on any organ or system of the body. Alcoholic liver disease (ALD) is the most prevalent cause of advanced liver disease in Europe. In ALD, only alcohol abstinence was associated with a better long-term survival. Therefore, current effective therapeutic strategy should be oriented towards achieving alcohol abstinence or a significant reduction in alcohol consumption. Screening all primary care patients to detect those cases with alcohol abuse has been proposed as population-wide preventive intervention in primary care. It has been suggested that in patients with mild alcohol use disorder the best approach is brief intervention in the primary care setting with the ultimate goal being abstinence, whereas patients with moderate-to-severe alcohol use disorder must be referred to specialized care where detoxification and medical treatment of alcohol dependence must be undertaken.

    The role alcohol abuse plays in criminality has been a matter of primary concern for scholars for decades, as indicated by numerous studies and research projects. Most of these studies focus on determining the presence of a relationship between criminal behaviour and alcohol use, and whether criminal inclinations increase with the consumption of alcohol. Research shows that alcohol use indeed increases the risk of criminal behaviour, and that there is an especially strong and consistent correlation between alcohol abuse and violent crimes. However, researchers still disagree on the exact extent to which alcohol use effects criminality, and on the mechanisms causing alcohol to induce violent behaviour. A significant proportion of studies have focused in recent years on aggressive behaviour as a result of drinking alcohol. One of the most important means of measurement is the study of violent behaviour in places where alcohol is on sale. Studying the forms and frequency of violence in pubs and near off-licence stores greatly enables experts to understand the general context of the problem. This is the reason for the increasing interest in the topic throughout the past few decades. The present study focuses mainly on the literature published in English and German in leading journals of criminology since 1980, as well as on the most recent and fundamental publications on the topic, with special regard to results concerning drinking habits, and the relationship between drinking alcohol and violent or criminal behaviour, respectively.

  6. Alcohol and suicidal behavior.

    PubMed

    Hufford, M R

    2001-07-01

    Alcohol dependence and alcohol intoxication are important risk factors for suicidal behavior. However, the mechanism for the relationship remains unclear. This review presents a conceptual framework relating alcohol to suicidal behavior. Distal risk factors create a statistical potential for suicide. Alcohol dependence, as well as associated comorbid psychopathology and negative life events, act as distal risk factors for suicidal behavior. Proximal risk factors determine the timing of suicidal behavior by translating the statistical potential of distal risk factors into action. The acute effects of alcohol intoxication act as important proximal risk factors for suicidal behavior among the alcoholic and nonalcoholic alike. Mechanisms responsible for alcohol's ability to increase the proximal risk for suicidal behavior include alcohol's ability to: (1) increase psychological distress, (2) increase aggressiveness, (3) propel suicidal ideation into action through suicide-specific alcohol expectancies, and (4) constrict cognition which impairs the generation and implementation of alternative coping strategies. Moreover, the proximal risk factors associated with acute intoxication are consistent with Baumeister's (1990) escape theory of suicide. Suggestions for additional research are discussed, including the possibility that a nonlinear cusp catastrophe model characterizes the relationship between alcohol intoxication and suicidal behavior.

  7. Genetics of alcoholism.

    1985-12-01

    Great progress has been made by research on the contribution genetic factors make to a vulnerability toward alcoholism. Animal studies have demonstrated the importance of genetics in ethanol preference and levels of consumption, and human family, twin, and adoption research have revealed a 4-fold higher risk for offspring of alcoholics, even if they were adopted out at birth. The work presented in this symposium reviews the ongoing search for genetic trait markers of a vulnerability toward alcoholism. Dr. Li has used both animal and human research to demonstrate the possible importance of the genetic control of enzymes involved in ethanol metabolism and has worked to help develop an animal model of alcoholism. The possible importance of subgroups with different levels of predisposition toward alcoholism is emphasized by Dr. Cloninger. An overview of the studies of sons of alcoholics, given by Dr. Schuckit, reveals the potential importance of a decreased intensity of reaction to ethanol as part of a predisposition toward alcoholism and discusses the possible impact of some brain waves and ethanol metabolites to an alcoholism vulnerability. Dr. Deitrich reviews interrelationships between studies of animals and humans in the search for factors involved in a genetic vulnerability toward alcoholism. Taken together, these presentations underscore the importance of genetic factors in alcoholism, review animal and human research attempting to identify markers of a vulnerability, and reveal the high level of interaction between human and animal research.

    This article summarizes the proceedings of a symposium presented at the 2003 RSA Meeting in Ft. Lauderdale, Florida, organized and chaired by Nancy Barnett. The purpose of the symposium was to present information and efficacy data about approaches to brief intervention with students who get into trouble on their campuses for alcohol and as a result are required to attend alcohol education or counseling. Presentations were (1) Differences Between Mandated College Students and Their Peers on Alcohol Use and Readiness to Change, by Tracy O’Leary Tevyaw; (2) An Effective Alcohol Prevention Program for Mandated College Students, by Kim Fromme; (3) Two Brief Alcohol Interventions for a Referred College Population, by Kate Carey; and (4) Brief Motivational Intervention With College Students Following Medical Treatment or Discipline for Alcohol, by Nancy Barnett. The data presented in this symposium indicated that students who are evaluated or disciplined for alcohol use are on average heavy drinkers who drink more heavily than their closest peers. Brief intervention approaches described by the speakers included group classroom sessions, individual motivational intervention, individual alcohol education, and computerized alcohol education. Reductions in consumption and problems were noted across the various intervention groups. Brief motivational intervention as a general approach with mandated students shows promise in that it reduced alcohol problems in a group of mandated students who were screened for being at risk (in the Borsari and Carey study) and increased the likelihood that students would attend further counseling (in the Barnett study).

    2011-01-01

    We examined 62 telehealth websites using four assessment criteria: design, literacy, information and telehealth content. The websites came from the member list of the American Telemedicine Association and the Office for the Advancement of Telehealth and partner sites, and were included if they were currently active and at least three clicks deep. Approximately 130 variables were examined for each website by two independent researchers. The websites reviewed contained most of the design variables (mean 74%, SD 6), but fewer of those relating to literacy (mean 26%, SD 6), website information (mean 35%, SD 16) and telehealth content (mean 37%, SD 18). Only 29% of websites encouraged users to ask about telehealth, and 19% contained information on overcoming telehealth barriers. Nonetheless, 84% promoted awareness of telehealth. All evaluation assessments were significantly correlated with each other except for literacy and information. The present study identified various matters that should be addressed when developing telehealth websites. Although much of this represents simple common sense in website design, our evaluation demonstrates that there is still much room for improvement.

    Objective The present study attempted to determine if behavioral economic indices of elevated alcohol reward value, measured before and immediately after a brief alcohol intervention, predict treatment response. Method Participants were 133 heavy drinking college students (49.6% female, 51.4% male; 64.3% Caucasian, 29.5% African American) who were randomized to one of three conditions: motivational interviewing plus personalized feedback (BMI), computerized personalized feedback intervention (e-CHUG), and assessment only. Results Baseline levels of alcohol demand significantly predicted drinks per week and alcohol problems at 1-month (demand intensity= maximum expenditure) and 6-month (relative discretionary expenditures on alcohol) follow-up. BMI and e-CHUG were associated with an immediate post-session reduction in alcohol demand (p < .001, ηρ2 = .29) that persisted at the 1-month follow-up, with greater post-session reductions in the BMI condition (p = .02, ηρ2 = .06). Reductions in demand intensity and Omax (maximum expenditure) immediately post-intervention significantly predicted drinking reductions at one-month follow up (p = .04, ΔR2 = .02 & p = .01, ΔR2 = .03, respectively). Reductions in relative discretionary expenditures on alcohol at 1-month significantly predicted drinking (p = .002, ΔR2 = .06,) and alcohol problem (p < .001, ΔR2 = .13) reductions at the 6-month follow-up. Conclusions These results suggest that behavioral economic reward value indices may function as risk factors for poor intervention response and as clinically-relevant markers of change in heavy drinkers.

    This paper describes how the Atlas of Human Cardiac Anatomy website can be used to improve cardiac device design throughout the process of development. The Atlas is a free-access website featuring novel images of both functional and fixed human cardiac anatomy from over 250 human heart specimens. This website provides numerous educational tutorials on anatomy, physiology and various imaging modalities. For instance, the 'device tutorial' provides examples of devices that were either present at the time of in vitro reanimation or were subsequently delivered, including leads, catheters, valves, annuloplasty rings and stents. Another section of the website displays 3D models of the vasculature, blood volumes and/or tissue volumes reconstructed from computed tomography and magnetic resonance images of various heart specimens. The website shares library images, video clips and computed tomography and MRI DICOM files in honor of the generous gifts received from donors and their families.

    2015-11-02

    Alcoholic liver disease is one of the most prevalent liver diseases worldwide, and a major cause of morbidity and mortality. Alcoholic hepatitis is a severe form of liver injury in patients with alcohol abuse, can present as an acute on chronic liver failure associated with a rapid decline in liver synthetic function, and consequent increase in mortality. Despite therapy, about 30%-50% of patients with severe alcoholic hepatitis eventually die. The pathogenic pathways that lead to the development of alcoholic hepatitis are complex and involve oxidative stress, gut dysbiosis, and dysregulation of the innate and adaptive immune system with injury to the parenchymal cells and activation of hepatic stellate cells. As accepted treatment approaches are currently limited, a better understanding of the pathophysiology would be required to generate new approaches that improve outcomes. This review focuses on recent advances in the diagnosis, pathogenesis of alcoholic hepatitis and novel treatment strategies.

    Diagnosis of alcoholism is very important, given its high prevalence and possibility of influencing the disease course. For this reason, the so-called biological markers of alcoholism are useful. These are analytic parameters that alter in the presence of excessive alcohol consumption. The two most relevant markers are the gamma-glutamyltranspeptidase and carbohydrate deficient transferrin. With this clinical comment, we aim to contribute to the knowledge of these tests and promote its use in the clinical practice.

    Introduction: Nowadays, hospitals have turned increasingly towards the Internet and develop their own web presence. Hospital Websites could be operating as effective web resources of information and interactive communication mediums to enhance hospital services to the public. Aim: Therefore, the aim of this study was to assess the quality of websites in Tehran’s public hospitals. Material and methods: This cross-sectional analysis involved all public hospitals in Iran’s capital city, Tehran, with a working website or subsites between April and June, 2014 (N=59). The websites were evaluated using three validated instruments: a localized checklist, Google page rank, and the Alexa traffic ranking. The mentioned checklist consisted of 112 items divided into five sections: technical characteristics, hospital information and facilities, medical services, interactive on-line services and external activities. Data were analyzed using descriptive and analytical statistics. Results: The mean website evaluation score was 45.7 out of 224 for selected public hospitals. All the studied websites were in the weak category based on the earned quality scores. There was no statistically significant association between the website evaluation score with Google page rank (P=0.092), Alexa global traffic rank and Alexa traffic rank in Iran (P>0.05). The hospital websites had a lower quality score in the interactive online services and external activities criteria in comparing to other criteria. Due to the low quality level of the studied websites and the importance of hospital portals in providing information and services on the Internet, the authorities should do precise planning for the appreciable improvement in the quality of hospital websites.

    Summary Background The Website Developmental Model for the Healthcare Consumer (WDMHC) is an extensive and successfully evaluated framework that incorporates user-centered design principles. However, due to its extensiveness its application is limited. In the current study we apply a subset of the WDMHC framework in a case study concerning the development and evaluation of a website aimed at childhood cancer survivors (CCS). Objective To assess whether the implementation of a limited subset of the WDMHC-framework is sufficient to deliver a high-quality website with few usability problems, aimed at a specific patient population. Methods The website was developed using a six-step approach divided into three phases derived from the WDMHC: 1) information needs analysis, mock-up creation and focus group discussion; 2) website prototype development; and 3) heuristic evaluation (HE) and think aloud analysis (TA). The HE was performed by three double experts (knowledgeable both in usability engineering and childhood cancer survivorship), who assessed the site using the Nielsen heuristics. Eight end-users were invited to complete three scenarios covering all functionality of the website by TA. Results The HE and TA were performed concurrently on the website prototype. The HE resulted in 29 unique usability issues; the end-users performing the TA encountered eleven unique problems. Four issues specifically revealed by HE concerned cosmetic design flaws, whereas two problems revealed by TA were related to website content. Conclusion Based on the subset of the WDMHC framework we were able to deliver a website that closely matched the expectancy of the end-users and resulted in relatively few usability problems during end-user testing. With the successful application of this subset of the WDMHC, we provide developers with a clear and easily applicable framework for the development of healthcare websites with high usability aimed at specific medical populations.

    Background Alcohol-induced intestinal dysbiosis disrupts homeostatic gut-liver axis function and is essential in the development of alcoholic liver disease. Here, we investigate changes in enteric microbiome composition in a model of early alcoholic steatohepatitis and dissect the pathogenic role of intestinal microbes in alcohol-induced liver pathology. Materials and methods Wild type mice received a 10-day diet that was either 5% alcohol-containing or an isocaloric control diet plus a single binge. 16S rDNA sequencing defined the bacterial communities in the cecum of alcohol- and pair-fed animals. Some mice were treated with an antibiotic cocktail prior to and throughout alcohol feeding. Liver neutrophils, cytokines and steatosis were evaluated. Results Acute-on-chronic alcohol administration induced shifts in various bacterial phyla in the cecum, including increased Actinobacteria and a reduction in Verrucomicrobia driven entirely by a reduction in the genus Akkermansia. Antibiotic treatment reduced the gut bacterial load and circulating bacterial wall component lipopolysaccharide (LPS). We found that bacterial load suppression prevented alcohol-related increases in the number of myeloperoxidase- (MPO) positive infiltrating neutrophils in the liver. Expression of liver mRNA tumor necrosis factor alpha (Tnfα), C-X-C motif chemokine ligand 1 (Cxcl1) and circulating protein monocyte chemoattractant protein-1 (MCP-1) were also reduced in antibiotic-treated alcohol-fed mice. Alcohol-induced hepatic steatosis measured by Oil-Red O staining was significantly reduced in antibiotic treated mice. Genes regulating lipid production and storage were also altered by alcohol and antibiotic treatment. Interestingly, antibiotic treatment did not protect from alcohol-induced increases in serum aminotransferases (ALT/AST). Conclusions Our data indicate that acute-on-chronic alcohol feeding alters the microflora at multiple taxonomic levels and identifies loss of Akkermansia as an

    Background The use of electronic interventions (e-interventions) may improve treatment of alcohol misuse. Purpose To characterize treatment intensity and systematically review the evidence for efficacy of e-interventions, relative to controls, for reducing alcohol consumption and alcohol-related impairment in adults and college students. Data Sources MEDLINE (via PubMed) from January 2000 to March 2015 and the Cochrane Library, EMBASE, and PsycINFO from January 2000 to August 2014. Study Selection English-language, randomized, controlled trials that involved at least 50 adults who misused alcohol; compared an e-intervention group with a control group; and reported outcomes at 6 months or longer. Data Extraction Two reviewers abstracted data and independently rated trial quality and strength of evidence. Data Synthesis In 28 unique trials, the modal e-intervention was brief feedback on alcohol consumption. Available data suggested a small reduction in consumption (approximately 1 drink per week) in adults and college students at 6 months but not at 12 months. There was no statistically significant effect on meeting drinking limit guidelines in adults or on binge-drinking episodes or social consequences of alcohol in college students. Limitations E-interventions that ranged in intensity were combined in analyses. Quantitative results do not apply to short-term outcomes or alcohol use disorders. Conclusion Evidence suggests that low-intensity e-interventions produce small reductions in alcohol consumption at 6 months, but there is little evidence for longer-term, clinically significant effects, such as meeting drinking limits. Future e-interventions could provide more intensive treatment and possibly human support to assist persons in meeting recommended drinking limits.

    This study investigates pathways from alcohol outcome expectancies to alcohol-related problems (ARPs), considering alcohol volume and episodic heavy drinking (EHD) as potential mediators. It is further examined whether these pathways vary by age. The population-based sample comprised 6,823 individuals aged 18 to 64 years reporting alcohol use in the past year. Direct and indirect effects of five alcohol expectancies (social assertiveness, tension reduction, sexual enhancement, cognitive impairment, aggression) and alcohol use (average daily intake, EHD) on a latent measure of ARPs (six items of the Alcohol Use Disorders Identification Test) were investigated. A multiple-group structural equation model with three age groups (18 to 24, 25 to 44, 45 to 64 years) was examined. In individuals aged 18 to 24 years, social assertiveness expectancies were positively associated with average intake and EHD, which in turn were associated with more ARPs. In addition, expectancies related to cognitive impairment and aggression were directly linked to more ARPs without mediation in this age group. In individuals aged 25 years and older, tension reduction expectancies were associated with more ARPs through increased average intake. In contrast, high scores on cognitive impairment were associated with lower average intake and in turn with fewer ARPs. Challenging expectancies of sociability in young and expectancies of relaxation in mid adulthood might help decrease high-risk drinking and subsequently ARPs. Considering negative alcohol expectancies may help to identify younger individuals at high risk for ARPs, even if they have not previously exhibited repeated excessive drinking.

    Alcohol is a major cause of liver cirrhosis in the Western world and accounts for the majority of cases of liver cirrhosis seen in district general hospitals in the UK. The three most widely recognised forms of alcoholic liver disease are alcoholic fatty liver (steatosis), acute alcoholic hepatitis, and alcoholic cirrhosis. The exact pathogenesis of alcoholic liver injury is still not clear but immune mediated and free radical hepatic injury are thought to be important. There is increasing interest in genetic factors predisposing to hepatic injury in susceptible individuals. Diagnosis is based on accurate history, raised serum markers such as γ-glutamyltransferase, mean corpuscular volume, and IgA and liver histology when obtainable. Abstinence is the most important aspect of treatment. Newer drugs such as acamprosate and naltrexone are used to reduce alcohol craving. Vitamin supplements and nutrition are vital while corticosteroids have a role in acute alcoholic hepatitis where there is no evidence of gastrointestinal haemorrhage or sepsis. Liver transplantation has excellent results in abstinent patients with end stage liver disease but there are concerns about recidivism after transplant.

    A mild step and atom-economical nonepimerizing chemo- and enantioselective N-alkylating procedure has been developed via oxidation/imine-iminium formation/reduction cascade using TEMPO-BAIB-HEH-Brønsted acid catalysis in DMPU as solvent and a stoichiometric amount of amine. The optimized conditions were further extended for the nonenzymatic kinetic resolution of the chiral amine thus formed under nonenzymatic in situ hydrogen-transfer conditions using VAPOL-derived phosphoric acid (VAPOL-PA) as the Brønsted acid catalyst. The enantioselective cascade of the presented reaction was successfully utilized in the synthesis of octahydropyrazinopyridoindole and its higher ring analogues.

    Background Purchasing electronic health records (EHRs) typically follows a process in which potential adopters actively seek information, compare alternatives, and form attitudes towards the product. A potential source of information on EHRs that can be used in the process is vendor websites. It is unclear how much product information is presented on EHR vendor websites or the extent of its value during EHR purchasing decisions. Objective To explore what features of EHR systems are presented by vendors in Ontario, Canada, on their websites, and the persuasive means they use to market such systems; to compare the online information available about primary care EHR systems with that about hospital EHR systems, and with data compiled by OntarioMD, a regional certifying agency. Methods A list of EHR systems available in Ontario was created. The contents of vendor websites were analyzed. A template for data collection and organization was developed and used to collect and organize information on the vendor, website content, and EHR features. First, we mapped information on system features to categories based on a framework from the Institute of Medicine (IOM). Second, we used a grounded theory–like approach to explore information for building consumer confidence in the vendor and product, and the various persuasive strategies employed on vendor websites. All data were first coded by one researcher. A peer reviewer independently analyzed a randomly chosen subset of the websites (10 of 21; 48%) and provided feedback towards a unified coding scheme. All data were then re-coded and categorized into themes. Finally, we compared information from vendor websites and data gathered by OntarioMD. Results Vendors provided little specific product information on their websites. Only two of five acute care EHR websites (40%) and nine of 16 websites for primary care systems (56%) featured seven or all eight of the IOM components. Several vendor websites included system interface

    The study investigated prenatal alcohol consumption and knowledge of alcohol risks and fetal alcohol syndrome among Korean women. The participants were 221 Korean women who attended the post-partum care centers in Seoul, Korea. The data included the participants' background characteristics, quantity-frequency typology, Student Alcohol Questionnaire, and a scale on the participants' knowledge of fetal alcohol syndrome. Alcohol was consumed during pregnancy by 12.7% of the participants. Of these, 60.7% drank alcohol with their spouse. A few participants reported that nurses identified their drinking habits and gave them information on alcohol consumption and fetal alcohol syndrome. Most of the participants did not have the opportunity for prenatal counseling about fetal alcohol syndrome. The knowledge level regarding alcohol risks and fetal alcohol syndrome among the participants was poor. Alcohol consumption before pregnancy was significantly related to prenatal alcohol consumption. Prenatal alcohol consumption was not related to knowledge about alcohol consumption and fetal alcohol syndrome. The assessment of alcohol consumption and counseling about alcohol are needed for pregnant women in order to prevent fetal alcohol syndrome.

  16. Defining maximum levels of higher alcohols in alcoholic beverages and surrogate alcohol products.

    PubMed

    Lachenmeier, Dirk W; Haupt, Simone; Schulz, Katja

    2008-04-01

    Higher alcohols occur naturally in alcoholic beverages as by-products of alcoholic fermentation. Recently, concerns have been raised about the levels of higher alcohols in surrogate alcohol (i.e., illicit or home-produced alcoholic beverages) that might lead to an increased incidence of liver diseases in regions where there is a high consumption of such beverages. In contrast, higher alcohols are generally regarded as important flavour compounds, so that European legislation even demands minimum contents in certain spirits. In the current study we review the scientific literature on the toxicity of higher alcohols and estimate tolerable concentrations in alcoholic beverages. On the assumption that an adult consumes 4 x 25 ml of a drink containing 40% vol alcohol, the maximum tolerable concentrations of 1-propanol, 1-butanol, 2-butanol, isobutanol, isoamyl alcohol and 1-hexanol in such a drink would range between 228 and 3325 g/hl of pure alcohol. A reasonable preliminary guideline level would be 1000 g/hl of pure alcohol for the sum of all higher alcohols. This level is higher than the concentrations usually found in both legal alcoholic beverages and surrogate alcohols, so that we conclude that scientific data are lacking so far to consider higher alcohols as a likely cause for the adverse effects of surrogate alcohol. The limitations of our study include the inadequate toxicological data base leading to uncertainties during the extrapolation of toxicological data between the different alcohols, as well as unknown interactions between the different higher alcohols and ethanol.
