    Alcohol dependence is a major public health problem worldwide. Brain and behavioral disruptions including changes in cognitive abilities are common features of alcohol addiction. Thus, the present study was aimed to investigate spatial learning and memory in 29 alcoholic men undergoing alcohol detoxification by using a virtual Morris maze task. As age-matched controls we recruited 29 men among occasional drinkers without history of alcohol dependence and/or alcohol related diseases and with a negative blood alcohol level at the time of testing. We found that the responses to the virtual Morris maze are impaired in men undergoing alcohol detoxification. Notably they showed increased latencies in the first movement during the trials, increased latencies in retrieving the hidden platform and increased latencies in reaching the visible platform. These findings were associated with reduced swimming time in the target quadrant of the pool where the platform had been during the 4 hidden platform trials of the learning phase compared to controls. Such increasing latency responses may suggest motor control, attentional and motivational deficits due to alcohol detoxification. PMID:26143187

    "To quit drinking" is not the panacea of alcohol dependence treatment; it is only its first step. Abstinence should be considered more as a mean than a purpose of the after-withdrawal cares. The frequent resistance of the alcoholic patient to undertake in a long term abstinence can be by-passed by suggesting to fix himself renewable terms for periods during which he feels rather confident to raise the bet of a "most accomplished possible" abstinence. To facilitate the realization and the preservation of this abstinence in the best conditions (potentiation of the profits and minimization of the difficulties), a "therapeutic menu" will be proposed to the patient besides a "minimum plan" containing a medical follow-up over one year, with variable frequency of visits according to the evolution and the prescription of one or two anti-craving drugs registered. Psychotherapies using different techniques as Cognitive Behavioural Therapy, group therapy or psychoanalysis could be proposed after a necessary clarification to the patients of the mechanism of action of each and the waited profits. In the final, two thirds of the patients with alcohol dependence fire in one year a profit of their treatments; the practitioner takes, actually, no risk and should propose systematically a project to the only 20% of them who come to consult him.

    Background This study examined predictors associated with readmission to detoxification in a sample of adult Alaska Native patients admitted to inpatient alcohol detoxification. Even though Alaska Native people diagnosed with alcoholism have been identified as frequent utilizers of the health care system and at elevated risk of death, little is known about factors associated with readmission to detoxification for this group. Methods We sought to predict readmission using a retrospective cohort study. The sample included 383 adult Alaska Native patients admitted to an inpatient detoxification unit and diagnosed with alcohol withdrawal during 2006 and 2007. Cox proportional hazard modeling was used to estimate unadjusted and adjusted associations with time to readmission within one year. Results Forty-two percent of the patients were readmitted within one year. Global Assessment Functioning (GAF; Axis V in the multi-axial diagnostic system of the Diagnostic and Statistical Manual of Mental Disorders [DSM IV]) score measured at the time of intake was associated with readmission. A one point increase in the GAF score (HR = .96, 95% CL = .94, .99, P = .002) was associated with a four percent decrease in readmission. The results also indicated that the GAF mediated the relationship between readmission and: employment and housing status. Conclusions The GAF measures both illness severity and adaptive functioning, is part of standard behavioral health assessments, and is easy to score. Readmission rates potentially could be decreased by creating clinical protocols that account for differences in adaptive functioning and illness severity during detoxification treatment and aftercare.

    Contrary to a published report, blood acetaldehyde concentrations become undetectable in patients 1--2 days following admission for alcohol detoxification. The persistently elevated blood acetaldehydes reported by others probably were due to artifactual formation during analysis. Nevertheless, our admission blood acetaldehyde concentrations are significant enough to support the contention that acetaldehyde has a cytotoxic role in alcoholic disease. PMID:663401

    Forty-eight patients undergoing inpatient detoxification for alcohol dependence were assigned to either brief advice (BA) to attend Alcoholics Anonymous or a motivational enhancement for 12-step involvement (ME-12) intervention that focused on increasing involvement in 12-step self-help groups. Attendance at 12-step groups did not differ significantly by treatment condition over 6 months of follow-up, nor did drinking outcomes. There was a significant interaction between 12-step experience and treatment condition, indicating that ME-12 was associated with relatively better alcohol outcomes at the low ends of 12-step experience, whereas BA was associated with relatively better outcomes at the high ends of 12-step experience. Results indicate that among patients undergoing alcohol detoxification, ME-12 may be beneficial only for those who have little experience with 12-step groups. PMID:15301659

    Korean pear (Pyrus pyrifolia cv. Shingo) has been used as a traditional medicine for alleviating alcohol hangover. However, scientific evidence for its effectiveness or mechanism is not clearly established. To investigate its mechanism of alcohol detoxification, both in vitro and in vivo studies were performed with an aldehyde dehydrogenase 2 (ALDH2) alternated animal model. The pear extract (10 mL/kg bw) was administered to Aldh2 normal (C57BL/6) and deficient (Aldh2 -/-) male mice. After 30 min, ethanol (1 g or 2 g/kg bw) was administered to the mice via gavage. Levels of alcohol and acetaldehyde in blood were quantified by GC/MS. First, it was observed that the pears stimulated both alcohol dehydrogenase (ADH) and ALDH activities by 2∼3-  and 1.3-fold in in vitro studies, respectively. Second, mouse PK data (AUC(∞) and C(max) ) showed that the pear extract decreased the alcohol level in blood regardless of ALDH2 genotype. Third, the pear increased the acetaldehyde level in blood in Aldh2 deficient mice but not in Aldh2 normal mice. Therefore, the consistent in vitro and in vivo data suggest that Korean pears stimulate the two key alcohol-metabolizing enzymes. These stimulations could be the main mechanism of the Korean pear for alcohol detoxification. Finally, the results suggest that polymorphisms of human ALDH2 could bring out individual variations in the effects of Korean pear on alcohol detoxification. PMID:22451246

    To determine if the addition of a behavioral intervention during alcohol detoxification would facilitate initiation of subsequent care, we randomized 150 detoxification patients to receive: treatment as usual (TAU), a Motivation Enhancement Therapy (MET) intervention, or a Peer-delivered Twelve Step Facilitation (P-TSF) intervention. The main outcome was the initiation of any type of subsequent care (i.e., professional treatment or self-help) within 30 and 90 days of discharge. Other outcomes included: alcohol and drug use, completion of subsequent professional treatment, and readmission for detoxification. The mean age of the participants was 45 years; 65% were men, and 84% were white. At the 30-day follow-up, there was no significant difference among the groups in the rate of initiation of any type of subsequent care (82%, 74%, and 82% respectively, p = 0.617); however, the MET group had significantly more patients initiate subsequent inpatient treatment by the 90-day follow-up compared to the P-TSF group (31% and 61%, p = 0.007) and a greater proportion of MET participants completed subsequent inpatient treatment compared to both TAU and P-TSF. There were no differences in drinking-related outcomes (e.g., number of days before first drink, percent days abstinent) between the groups. We conclude that MET during detoxification may provide additional benefits in terms of initiating and maintaining patients in aftercare inpatient treatment programs. PMID:21491295

    In this study, heat-treated cucumber juice was assessed for its protective effect on blood alcohol levels and hepatic alcohol metabolic enzyme system in experimental rats. Initially, during detoxification of alcohol, all groups were orally dosed to 22% alcohol (6ml/kg body weight) along with different concentrations of heat-treated cucumber juice (10, 100 and 500mg/kg) and commercial goods for hangover-removal on sale (2ml/kg). Cucumber juice was dosed before 30 min, and simultaneously after 30min of alcohol administration, and its hepatoprotective effect on blood alcohol levels and hepatic alcohol metabolic enzyme system in experimental rats was evaluated. As a result, after 7h, remarkable reduction was found in the blood alcohol levels for all concentrations of cucumber juice treatment. Treatment with cucumber juice resulted in increasing dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) enzymatic activities in rat liver at 9h after alcohol administration thereby stimulated blood alcohol metabolism as compared with control group. The effect of heat-treated cucumber juice on alcohol detoxification was observed only in the rats treated before 30min from alcohol administration. These findings indicate that heat-treated cucumber juice has significant protective effect on alcohol detoxification in experimental rats, suggesting its usefulness in the treatment of liver injury caused by alcohol consumption.

    The objective of this study was to verify the effects of ethanol consumption and alcohol detoxification on the biomechanics, area and thickness of cortical and trabecular bone in rat femur. This was an experimental study in which 18 male Wistar rats were used, with 40 days of age, weighing 179 ± 2.5 g. The rats were divided into three groups (n=06): CT (control), AC (chronic alcoholic), DT (detoxification). After experimental procedures, the animals were euthanized by an overdose of the anesthetic and their femurs were collected for mechanical testing and histological processing. All animals did not present malnutrition or dehydration during experimentation period. Morphometric analysis of cortical and trabecular bones in rat femurs demonstrated that AC animals showed inferior dimensions and alcohol detoxification (DT) allowed an enhancement in area and thickness of cortical and trabecular bone. Material and structural properties data of AC group highlighted the harmful effects of ethanol on bone mechanical properties. The results of this study demonstrated that chronic alcoholic rats (AC) presented major bone damage in all analyzed variables. Those findings suggested that alcohol detoxification is highly suggested in pre-operative planning and this corroborates to the success of bone surgery and bone tissue repair.

    Introduction Stronger alcohol policies predict decreased alcohol consumption and binge drinking in the United States. We examined the relationship between the strength of states’ alcohol policies and alcoholic cirrhosis mortality rates. Methods We used the Alcohol Policy Scale (APS), a validated assessment of policies of the 50 US states and Washington DC, to quantify the efficacy and implementation of 29 policies. State APS scores (theoretical range, 0–100) for each year from 1999 through 2008 were compared with age-adjusted alcoholic cirrhosis death rates that occurred 3 years later. We used Poisson regression accounting for state-level clustering and adjusting for race/ethnicity, college education, insurance status, household income, religiosity, policing rates, and urbanization. Results Age-adjusted alcoholic cirrhosis mortality rates varied significantly across states; they were highest among males, among residents in states in the West census region, and in states with a high proportion of American Indians/Alaska Natives (AI/ANs). Higher APS scores were associated with lower mortality rates among females (adjusted incidence rate ratio [IRR], 0.91 per 10-point increase in APS score; 95% confidence interval [95% CI], 0.84–0.99) but not among males (adjusted IRR, 0.97; 95% CI, 0.90–1.04). Among non-AI/AN decedents, higher APS scores were also associated with lower alcoholic cirrhosis mortality rates among both sexes combined (adjusted IRR, 0.89; 95% CI, 0.82–0.97). Policies were more strongly associated with lower mortality rates among those living in the Northeast and West census regions than in other regions. Conclusions Stronger alcohol policy environments are associated with lower alcoholic cirrhosis mortality rates. Future studies should identify underlying reasons for racial/ethnic and regional differences in this relationship. PMID:26469950

    Aldehyde inhibitors such as furfural and 5-hydroxymethylfurfural (HMF) are generated from biomass pretreatment. Scheffersomyces stipitis is able to reduce furfural and HMF to less toxic furanmethanol and furan-2,5-dimethanol; however, the enzymes involved in the reductive reaction still remain unknown. In this study, transcription responses of two known and five putative alcohol dehydrogenase genes from S. stipitis were analyzed under furfural and HMF stress conditions. All the seven alcohol dehydrogenase genes were also cloned and overexpressed for their activity analyses. Our results indicate that transcriptions of SsADH4 and SsADH6 were highly induced under furfural and HMF stress conditions, and the proteins encoded by them exhibited NADH- and/or NADPH-dependent activities for furfural and HMF reduction, respectively. For furfural reduction, NADH-dependent activity was also observed in SsAdh1p and NAD(P)H-dependent activities were also observed in SsAdh5p and SsAdh7p. For HMF reduction, NADPH-dependent activities were also observed in SsAdh5p and SsAdh7p. SsAdh4p displayed the highest NADPH-dependent specific activity and catalytic efficiency for reduction of both furfural and HMF among the seven alcohol dehydrogenases. Enzyme activities of all SsADH proteins were more stable under acidic condition. For most SsADH proteins, the optimum temperature for enzyme activities was 30 °C and more than 50 % enzyme activities remained at 60 °C. Reduction activities of formaldehyde, acetaldehyde, isovaleraldehyde, benzaldehyde, and phenylacetaldehyde were also observed in some SsADH proteins. Our results indicate that multiple alcohol dehydrogenases in S. stipitis are involved in the detoxification of aldehyde inhibitors derived from lignocellulosic biomass conversion. PMID:23912116

    The purpose of this study is to describe the characteristics of a statistical technique appropriate for analysing multi-episode data (multi-episode survival analysis), and to show its application in modelling the flow of readmissions at an inpatient detoxification unit. Data are from 784 opioid-dependent patients admitted at an inpatient detoxification unit, who totalled 1,255 admission episodes. Information stored prospectively at the unit database was reviewed for the following variables at the time of each patient discharge: episode serial number, sex, route of heroin administration, reason for discharge, time of discharge, and transition time (re-entry into the inpatient detoxification unit). Cox's semi-parametric regression model seems the most appropriate for describing the series of episodes. Amongst the parametric models, most noteworthy was the superior fit of the Gompertz-Makeham model, suggesting that the transition rate decreases monotonically with time. The influence of the variables assessed differed based on the serial number of the episode. The results suggest that multi-episode survival analysis is a statistical method that can fully address the long-term perspective on treatment utilization. PMID:17399908

    Compliance with pathways for hospitalised patients with alcohol dependency syndrome is often poor. A pathway for recognition and treatment of alcohol dependency was redesigned as part of a 12 month service improvement project in the acute medical unit using plan, do, study, act (PDSA) cycles. A needs assessment was undertaken: Audit data from 2013 showed over-prescription of chlordiazepoxide for detoxification treatment (DT) leading to prolonged hospital admissions with an average length of stay of 5.5 days in 2012/2013. Acceptability of screening tools was tested: Common screening tools (CEWA, AUDIT) were rejected by junior doctors due to the high number of questions as too cumbersome for routine practice. Compliance with usage in random samples over a three month period was persistently (n=10%. Testing of an abbreviated AUDIT questionnaire with only two questions and a specified threshold showed a AUROC of 1 (p<0.001 for correct identification). The screening tool was implemented in several PDSAs cycles. After the final cycle a random sample of 100 patients was reviewed for pathway compliance over a three months period. Eighty-six patients were screened with the two-question tool of these 18 were identified as possible risk. Of these 16 patients had the full AUDIT questionnaire, only eight with elevated values were started on DT. Overall compliance with the pathway increased to 84%. PMID:26734413

    Studies of ethyl glucuronide (EtG) blood kinetics have so far been performed on healthy volunteers with ingestion of low to moderate doses of ethanol. These data are not necessarily transferable to heavy drinkers where the consumed doses of ethanol are much higher. The aim of this study was to investigate the pharmacokinetics of EtG and ethyl sulphate (EtS) in blood in heavy drinkers after termination of alcohol ingestion. Sixteen patients from an alcohol withdrawal clinic were included directly after admission. Time of end of drinking, estimated daily intake of ethanol (EDI) and medical history were recorded. Three to five blood samples over 20-43 h were collected from each patient subsequent to admission. The median EDI was 172 g (range 60-564). The first sample was collected median 2.5 h after end of drinking (range 0.5-23.5). Two patients had levels of EtG and EtS below LOQ in all samples, the first collected 19.25 and 23.5 h after cessation of drinking, respectively. Of the remaining 14 patients, one subject, suffering from both renal and hepatic disease, showed concentrations of EtG and EtS substantially higher than the rest of the material. This patient's initial value of EtG was 17.9 mg/L and of EtS 5.9 mg/L, with terminal elimination half lives of 11.9 h for EtG and 12.5 h for EtS. Among the remaining 13 patients, the initial median values were 0.7 g/L (range 0-3.7) for ethanol, 1.7 mg/L (range 0.1-5.9) for EtG and 0.9 mg/L (range 0.1-1.9) for EtS. Elimination occurred with a median half-life of 3.3 h for EtG (range 2.6-4.3) and 3.6 h for EtS (range 2.7-5.4). In conclusion, elimination of EtG in heavy drinkers did not significantly differ from healthy volunteers, and EtS appeared to have similar elimination rate. In the present work, there was one exception to this, and we propose that this could be explained by the patient's renal disease, which would delay excretion of these conjugated metabolites.

    There has long been interest in utilizing photochemical methods for destroying hazardous organic materials. Researchers at the University of Dayton Research Institute (UDRI) have developed a unique photothermal process that overcomes many of the problems previously encountered with direct photochemical detoxification techniques. Specifically, it has been found that there are numerous advantages to conducting photochemical detoxification at relatively high temperatures. Under the conditions of simultaneous exposure to heat and ultraviolet (UV) radiation the rate of destructive photothermal reactions can be greatly increased and that these reactions result in the complete mineralization of the waste feed. Futhermore, it has been demonstrated that at the elevated temperatures used in this process the efficiency of UV radiation absorption also increases resulting in an overall improvement in process efficiency. These features (i.e., fast, efficient, and complete destruction of organic wastes) makes this process a promising technique for destroying hazardous organic wastes in the gas-phase.

    Background Many concerns about liver transplantation in alcoholic patients are related to the risk of alcohol recidivism. Starting from 2002, an Alcohol Addiction Unit was formed within the Liver Transplant Centre for the management of alcoholic patients affected by end-stage liver disease and included in the waiting list for transplantation. We evaluated retrospectively the impact of the Alcohol Addiction Unit on alcohol recidivism after transplantation. The relationship between alcohol recidivism and the duration of alcohol abstinence before transplant was evaluated as well. Methods Between 1995 and 2010, 92 cirrhotic alcoholic patients underwent liver transplantation. Clinical evaluation and management of alcohol use in these patients was provided by psychiatrists with expertise in addiction medicine not affiliated to the Liver Transplant Centre before 2002 (n=37; group A), or by the clinical staff of the Alcohol Addiction Unit within the Liver Transplant Centre starting from 2002 (n=55; group B). Results Group B, as compared to group A, showed a significantly lower prevalence of alcohol recidivism (16.4% vs. 35.1%; p=0.038) and a significantly lower mortality (14.5% vs. 37.8%; p=0.01). Furthermore, an analysis of group B patients with either ≥6 months or <6 months of alcohol abstinence before transplantation showed no difference in the rate of alcohol recidivism (21.1% vs. 15.4%; p=ns). Conclusions The presence of an Alcohol Addiction Unit within a Liver Transplant Centre reduces the risk of alcohol recidivism after transplantation. A pre-transplant abstinence period <6 months might be considered, at least in selected patients managed by an Alcohol Addiction Unit. PMID:23578009

    Aims To investigate the relationship between legalization of Sunday alcohol sales and alcohol consumption in the United States. Design State-level per capita consumption of beer, wine, and spirits was analyzed using difference-in-differences econometric methods. Setting United States. Participants 5 treatment states that repealed their laws restricting Sunday alcohol sales during 1990–2007 and 12 control states that retained their Sunday alcohol laws during the same period. Measurements Outcome measures are state-level per capita consumption of overall alcohol, beer, wine, and spirits. Findings Among the states that legalized Sunday sales of alcoholic beverages, Delaware, Pennsylvania, and New Mexico experienced significant increases in overall alcohol consumption (P<0.05). However, the effect of the legalization of Sunday alcohol sales in Massachusetts and Rhode Island on per capita alcohol consumption was insignificant (P=0.964 and P=0.367). Conclusions Three out of five states in the USA that repealed their laws restricting Sunday sale of alcoholic beverages during 1990–2007, experienced significant increases in per capita alcohol consumption. This finding implies that increased alcohol availability leads to an increase in alcohol consumption. PMID:24103041

    Detoxification refers to the safe discontinuation from a substance of dependence and is distinct from relapse prevention. Detoxification usually takes between a few days and a few weeks to complete, depending on the substance being misused, the severity of dependence and the support available to the user. Psychosocial therapies alongside pharmacological treatments are essential to improve outcome. The dependencies considered in this overview are detoxification from opioids (with methadone, buprenorphine, α2-adrenoceptor agonists and adjunct medications), alcohol (with benzodiazepines, anti-glutamatergics and γ-aminobutyric acid (GABA)-ergic drugs), stimulants and cannabis (with no clear recommended pharmacological treatments), benzodiazepines (with dose tapering) and nicotine (with nicotine replacement therapy, antidepressants and partial agonists). Evidence is limited by a lack of controlled trials robust enough for review bodies, and more research is required into optimal treatment doses and regimes, alone and in combination. PMID:24118014

    As domestic gas was detoxified in the United States, the rate of suicide by domestic gas decreased. During this time period (1950-60), there was a parallel increase in the per capita ownership of cars and an accompanying increase in the rate of suicide by motor vehicle exhaust. However, displacement of suicide method from domestic gas to car exhaust occurred only for males and not for females.

    Several studies have shown the opioid antagonist naltrexone to be effective when combined with psychosocial therapies for the treatment of patients who are dependent on alcohol with fixed medication and time (12 weeks). In this study, 121 nonabstinent outpatients with alcohol dependence (DSM-IV) were treated with sessions of cognitive coping skills (N = 67) or supportive therapy (N = 54) and either naltrexone 50 mg/day (N = 63) or placebo (N = 58) daily for the first 12 weeks and thereafter for 20 weeks only when craving alcohol (i.e., targeted medication) in a prospective one-center, dual, double-blind, randomized clinical trial. The dropout rate for all subjects was 16.5% during the first 12-week period and approximately twice that level by the end of the study. There were no significant group differences in study completion and therapy participation rates. After the continuous medication (12 weeks), the coping/naltrexone group had the best outcome, and coping/placebo had the worst. This difference remained during the targeted medication period (the following 20 weeks). Naltrexone was not better than placebo in the supportive groups, but it had a significant effect in the coping groups: 27% of the coping/naltrexone patients had no relapses to heavy drinking throughout the 32 weeks, compared with only 3% of the coping/placebo patients. The authors' data confirm the original finding of the efficacy of naltrexone in conjunction with coping skills therapy. In addition, their data show that detoxification is not required and that targeted medication taken only when craving occurs is effective in maintaining the reduction in heavy drinking.

    The central element of the "qualified withdrawal treatment" of alcohol dependence is - in addition to physical withdrawal treatment - psychotherapy. The treatment of the underlying addictive disorder that is displayed by intoxication, harmful behaviour and withdrawal symptoms is only possible with a combination of somatic and psychotherapeutic treatment elements. The successfully established multimodal therapy of the "qualified alcohol withdrawal treatment", postulated in the current S3-Treatment Guidelines, requires a multi-disciplinary treatment team with psychotherapeutic competence. The aim of the present work is to calculate the normative staff requirement of a guideline-based 21-day qualified withdrawal treatment and to compare the result with the staffing regulations of the German Institute for Hospital Reimbursement. The present data support the hypothesis that even in the case of a hundred per cent implementation of these data, adequate therapy of alcohol-related disorders, according to the guidelines, is not feasible. This has to be considered when further developing the finance compensation system based on the described superseded elements of the German Institute for Hospital Reimbursement. PMID:26842899

  10. Costs of Alcohol-Involved Crashes, United States, 2010

    2013-01-01

    This paper estimates total and unit costs of alcohol-involved crashes in the U.S. in 2010. With methods from earlier studies, we estimated costs per crash survivor by MAIS, body part, and fracture/dislocation involvement. We multiplied them times 2010 crash incidence estimates from NHTSA data sets, with adjustments for underreporting of crashes and their alcohol involvement. The unit costs are lifetime costs discounted at 3%. To develop medical costs, we combined 2008 Health Care Utilization Program national data for hospitalizations and ED visits of crash survivors with prior estimates of post-discharge costs. Productivity losses drew on Current Population Survey and American Time Use Survey data. Quality of life losses came from a 2011 AAAM paper and property damage from insurance data. We built a hybrid incidence file comprised of 2008–2010 and 1984–86 NHTSA crash surveillance data, weighted with 2010 General Estimates System weights. Fatality data came from the 2010 FARS. An estimated 12% of 2010 crashes but only 0.9% of miles driven were alcohol-involved (BAC > .05). Alcohol-involved crashes cost an estimated $125 billion. That is 22.5% of the societal cost of all crashes. Alcohol-attributable crashes accounted for an estimated 22.5% of US auto liability insurance payments. Alcohol-involved crashes cost $0.86 per drink. Above the US BAC limit of .08, crash costs were $8.37 per mile driven; 1 in 788 trips resulted in a crash and 1 in 1,016 trips in an arrest. Unit costs for crash survivors by severity are higher for impaired driving than for other crashes. That suggests national aggregate impaired driving cost estimates in other countries are substantial underestimates if they are based on all-crash unit costs. PMID:24406941

  11. A descriptive study of alcohol-dependent women attending Alcoholics Anonymous, a regional council on alcoholism and an alcohol treatment unit.

    1992-11-01

    A total of 86 women, attending three different agencies, were interviewed on their help-seeking behaviours for problem drinking. Each agency represented a different type of help available in the community. Self-help was represented by Alcoholics Anonymous; the non-statutory sector by a regional council on alcoholism's offices; and the statutory sector by an alcohol treatment unit's out-patient department. Differences between the groups in terms of demography and drinking history are explored in this paper. It was found that the regional council group resembled the female problem drinkers in other alcohol treatment agencies in terms of alcohol dependency, pattern of alcohol consumption and drinking styles, but differed in age and abstinence behaviour.

    Compounds such as furfural and 5-hydroxymethylfurfural (5-HMF) are generated through the dehydration of xylose and glucose, respectively, during dilute-acid pretreatment of lignocellulosic biomass and are also potent microbial growth and fermentation inhibitors. The enzymatic reduction of these furan aldehydes to their corresponding, and less toxic, alcohols is an engineering approach that has been successfully implemented in both Saccharomyces cerevisiae and ethanologenicEscherichia coli, but has not yet been investigated in thermophiles relevant to biofuel production through consolidated bioprocessing (CBP). Developing CBP-relevant biocatalysts that are either naturally resistant to such inhibitors, or are amenable to engineered resistance, is therefore, an important component in making biofuels production from lignocellulosic biomass feasible.

    2014-08-01

    The slow epidemic of liver disease in the UK over the past 30 years is a result of increased consumption of strong cheap alcohol. When we examined alcohol consumption in 404 subjects with a range of liver disease, we confirmed that patients with alcohol-related cirrhosis drank huge amounts of cheap alcohol, with a mean weekly consumption of 146 units in men and 142 in women at a median price of 33p/unit compared with £1.10 for low-risk drinkers. For the patients in our study, the impact of a minimum unit price of 50p/unit on spending on alcohol would be 200 times higher for patients with liver disease who were drinking at harmful levels than for low-risk drinkers. As a health policy, a minimum unit price for alcohol is exquisitely targeted at the heaviest drinkers, for whom the impact of alcohol-related illness is most devastating. PMID:25099842

    Abstract Objectives This study sought to assess the use of clinical detoxification therapies used by licensed naturopathic doctors (NDs) in the United States. Design This was a qualitative, descriptive, online survey of a convenience sample of NDs. Methods An online survey was conducted of NDs who were licensed in the United States. Responses were analyzed descriptively regarding the use of clinical detoxification therapies. Respondents were recruited from a membership list provided by the American Association of Naturopathic Physicians, and from alumni e-mail lists of Council of Naturopathic Medical Education accredited naturopathic medical schools. Results Surveys were sent out to 1442 e-mail addresses (261 were returned to sender); a total of 196 respondents completed the survey (16.6%). Ninety-two percent (92%) of respondents reported using clinical detoxification therapies. Over 75% of respondents utilized detoxification therapies primarily to treat patients for environmental exposures, general cleansing/preventive medicine, gastrointestinal disorders, and autoimmune disease. Regarding methods used, >75% reported using dietary measures, reducing environmental exposures, and using botanicals as detoxification therapies. Eighty-three percent (83%) of NDs surveyed reported using follow-up measurements to determine efficacy of detoxification therapies. The most common were patient symptom questionnaires (66%), patient medical histories (54%), and urinary provocative challenge testing (53%). Conclusions The majority of NDs responding to this survey reported routine use of clinical detoxification therapies to treat a range of medical conditions utilizing multiple therapeutic approaches. Although the majority of NDs reported using some follow-up measurements after detoxification therapy, few of these are an objective means to determine treatment efficacy. Further research is needed in the field of complementary and alternative medicine clinical detoxification to

    Purpose Few studies have compared acute use of alcohol in suicide decedents with that in a nonsuicide group. This study provides the first national analysis of acute use of alcohol prior to suicide compared with an estimate of acute use of alcohol in a living sample. Methods Pooled 2003-2011 National Violent Death Reporting System data were used to estimate the prevalence of postmortem blood alcohol content positivity (BAC >0.0 g/dl) and intoxication (BAC ≥ 0.08 g/dl). Population estimates of comparable use of alcohol (within the past 48 hours) were based on the National Epidemiologic Survey on Alcohol and Related Conditions. Results Compared to the living sample, male and female suicide decedents showed, respectively, a 1.83- (95% confidence interval [CI], 1.73-1.93) and 2.40-fold (95% CI, 2.24-2.57) increased risk of alcohol ingestion prior to their death after age, race/ethnicity, and chronic alcohol problems were controlled. Furthermore, male and female decedents exhibited, respectively, a 6.18- (95% CI, 5.57-6.86) and a 10.04-fold (95% CI, 8.67-11.64) increased risk of being intoxicated prior to their death after confounders were considered. Conclusions The findings underscore the crucial need to include among the essential components of suicide prevention policies programs that minimize use of alcohol, particularly drinking to intoxication.

  18. Youth exposure to alcohol advertising on radio--United States, June-August 2004.

    PubMed

    2006-09-01

    In the United States, more underage youth drink alcohol than smoke tobacco or use illicit drugs. Excessive alcohol consumption leads to many adverse health and social consequences and results in approximately 4,500 deaths among underage youth each year. Recent studies have emphasized the contribution of alcohol marketing to underage drinking and have demonstrated that a substantial proportion of alcohol advertising appears in media for which the audience composition is youth-oriented (i.e., composed disproportionately of persons aged 12-20 years). To determine the proportion of radio advertisements that occurred on radio programs with audiences composed disproportionately of underage youth and the proportion of total youth exposure to alcohol advertising that occurs as a result of such advertising, researchers at the Center on Alcohol Marketing and Youth (Health Policy Institute, Georgetown University, District of Columbia) evaluated the placement of individual radio advertisements for the most advertised U.S. alcohol brands and the composition of audiences in the largest 104 markets in the United States. This report summarizes the results of that study, which indicate that alcohol advertising is common on radio programs which have disproportionately large youth audiences and that this advertising accounts for a substantial proportion of all alcohol radio advertising heard by underage youth. These results further indicate that 1) the current voluntary standards limiting alcohol marketing to youth should be enforced and ultimately strengthened, and 2) ongoing monitoring of youth exposure to alcohol advertising should continue.

  19. What are the policy lessons of National Alcohol Prohibition in the United States, 1920-1933?

    PubMed

    Hall, Wayne

    2010-07-01

    National alcohol prohibition in the United States between 1920 and 1933 is believed widely to have been a misguided and failed social experiment that made alcohol problems worse by encouraging drinkers to switch to spirits and created a large black market for alcohol supplied by organized crime. The standard view of alcohol prohibition provides policy lessons that are invoked routinely in policy debates about alcohol and other drugs. The alcohol industry invokes it routinely when resisting proposals to reduce the availability of alcohol, increase its price or regulate alcohol advertising and promotion. Advocates of cannabis law reform invoke it frequently in support of their cause. This paper aims: (i) to provide an account of alcohol prohibition that is more accurate than the standard account because it is informed by historical and econometric analyses; (ii) to describe the policy debates in the 1920s and 1930s about the effectiveness of national prohibition; and (iii) to reflect on any relevance that the US experience with alcohol prohibition has for contemporary policies towards alcohol. It is incorrect to claim that the US experience of National Prohibition indicates that prohibition as a means of regulating alcohol is always doomed to failure. Subsequent experience shows that partial prohibitions can produce substantial public health benefits at an acceptable social cost, in the absence of substantial enforcement. PMID:20331549

    Background There are no existing data on alcoholic beverage prices and ethanol content at the level of alcohol brand. A comprehensive understanding of alcohol prices and ethanol content at the brand level is essential for the development of effective public policy to reduce alcohol use among underage youth. The purpose of this study was to comprehensively assess alcoholic beverage prices and ethanol content at the brand level. Methods Using online alcohol price data from 15 control states and 164 online alcohol stores, we estimated the average alcohol price and percentage alcohol by volume for 900 brands of alcohol, across 17 different alcoholic beverage types, in the United States in 2011. Results There is considerable variation in both brand-specific alcohol prices and ethanol content within most alcoholic beverage types. For many types of alcohol, the within-category variation between brands exceeds the variation in average price and ethanol content among the several alcoholic beverage types. Despite differences in average prices between alcoholic beverage types, in 12 of the 16 alcoholic beverage types, customers can purchase at least one brand of alcohol that is under one dollar per ounce of ethanol. Conclusions Relying on data or assumptions about alcohol prices and ethanol content at the level of alcoholic beverage type is insufficient for understanding and influencing youth drinking behavior. Surveillance of alcohol prices and ethanol content at the brand level should become a standard part of alcohol research. PMID:22316218

    2008-10-01

    The most rapidly growing segment of the US population is that of older adults (> or =65 years). Trends of aging adults (those aged > or =50 years) show that fewer women than men consume alcohol, women consume less alcohol than men, and total alcohol intake decreases after retirement. A U- or J-shaped relationship between alcohol intake and mortality exists among middle-aged (age 45 to 65 years) and older adults. Thus, alcohol can be considered either a tonic or a toxin in dose-dependent fashion. Active areas of research regarding the possible benefits of moderate alcohol consumption among aging individuals include oxidative stress, dementia, psychosocial functioning, dietary contributions, and disease prevention. Yet, due to the rising absolute number of older adults, there may be a silent epidemic of alcohol abuse in this group. Dietary effects of moderate and excessive alcohol consumption are reviewed along with mechanisms by which alcohol or phytochemicals modify physiology, mortality, and disease burden. Alcohol pharmacokinetics is considered alongside age-related sensitivities to alcohol, drug interactions, and disease-related physiological changes. International guidelines for alcohol consumption are reviewed and reveal that many nations lack guidelines specific to older adults. A review of national guidelines for alcohol consumption specific to older adults (eg, those offered by the National Institute on Alcohol Abuse) suggests that they may be too restrictive, given the current literature. There is need for greater quantification and qualification of per capita consumption, consumption patterns (quantity, frequency, and stratified combinations), and types of alcohol consumed by older adults in the United States.

    2013-01-01

    Background Several studies have found participants pour more than 1 standard drink or unit as their usual glass. This is the first study to measure actual and perceived amounts of alcohol in a self-defined usual glass of wines and spirits in the general population. Methods Participants were a convenience sample of adults who drink alcohol or who pour drinks for other people (n = 283, 54% women) at 6 sites in South East England. The survey was face to face and comprised a self-completion questionnaire and pouring task. Estimation accuracy, categorised as correct (±0.5 units), underestimate (>0.5 units), or overestimate (>0.5 units) was the main outcome. Results The mean number of units poured was 1.90 (SD 0.80; n = 264) for wine and 1.93 (SD 0.78; n = 201) for spirits. The amount of alcohol in a self-defined usual glass was estimated in 440 glasses (248 wine and 192 spirits). Overestimation took place in 42% glasses of spirit poured and 29% glasses of wine poured, and underestimation in 17 and 19%, respectively. Multinomial logistic regression found volume poured to be significantly associated with underestimating both wines and spirits, and additionally for wine only, belonging to a non-white ethnic group and being unemployed or retired. Not having a university degree was significantly associated with overestimating both drink types. Conclusions This study is the first in the general population and did not identify systematic underestimation of the amount of alcohol in a self-defined usual glass. Underestimation is significantly associated with volume poured for both drink types; therefore, advocating pouring smaller glasses could reduce underestimation of alcohol consumption. PMID:23278164

    SUMMARY BACKGROUND Excess alcohol use among tuberculosis (TB) patients complicates TB control strategies. OBJECTIVES To characterize the role of excess alcohol use in TB control, we describe the epidemiology of excess alcohol use and TB in the United States among those aged ≥15 years. DESIGN Using data reported to the National Tuberculosis Surveillance System, 1997–2012, we examined associations between excess alcohol use and TB treatment outcomes and markers for increased transmission (involvement in a local genotype cluster of cases) using multivariate logistic regression. We used Cox proportional hazards regression analysis to examine the relationship between excess alcohol use and the rate of conversion from positive to negative in sputum culture results. RESULTS Excess alcohol use was documented for 31 207 (15.1%) of 207 307 patients. Prevalence of excess alcohol use was greater among male patients (20.6%) and US-born patients (24.6%). Excess alcohol use was associated with a positive sputum smear result (aOR 1.23, 95%CI 1.18–1.28) and death during treatment (vs. completion of treatment) (aOR 1.16, 95%CI 1.10–1.22). The rate of culture conversion was higher among patients without excess alcohol use (adjusted hazard ratio 1.20, 95%CI 1.18–1.23). CONCLUSIONS Excess alcohol use was common among patients with TB, and was associated with TB transmission, lower rates of sputum culture conversion, and greater mortality. PMID:25519800

    1990-01-01

    Initiatives by individuals, private foundations and government have led to improvements in the United States in medical education dealing with alcohol and drug-related problems. Progress has been made, particularly in the past 5 years, in developing new medical school curricula and in faculty development. Greater activity by national professional organizations has helped raise the priority of training in alcohol- and drug-related areas for undergraduate and postgraduate medical education. As an example, Project ADEPT (Alcohol and Drug Education for Physician Training in primary care) at Brown University in Providence, Rhode Island, is described. The importance of positive and motivated faculty role models and of skills training is emphasized. PMID:2224678

  14. Drinking norms and alcohol-related problems in the United States.

    PubMed

    Linsky, A S; Colby, J P; Straus, M A

    1986-09-01

    One of Bales's three related hypotheses concerning how cultures or social structures influence the level of alcoholism in a population--that culturally determined attitudes toward drinking and intoxication determine whether alcohol will be used to relieve the stress generated in a society--is examined in the first systematic test of that hypothesis based on American data. A proscriptive norm index was computed for each of the 50 states based on percentage population residing in legally dry areas, the degree of legal restrictions on the sale or consumption of alcoholic beverages and the percentage population of Mormons and Fundamentalists. The most proscriptive states are located in the southern region of the United States. Proscriptive norms are significantly correlated with all of the indicators of alcohol-related problems studied. Most of the correlations remain significant when five other variables are controlled. Proscriptive norms are negatively correlated with the indicators of heavy drinking, but positively correlated with the "social disruptiveness" of alcohol (arrest data). Thus driving while intoxicated and other alcohol-related arrests do not appear to arise as a response to the total amount of drinking. Instead, such alcohol-related problems appear to be a response to the strong cultural disapproval of drinking, with the proscriptively oriented states experiencing the highest rates of disruptive behaviors related to alcohol. The findings are consistent with a social control explanation for this link. PMID:3762162

  15. The price of a drink: levels of consumption and price paid per unit of alcohol by Edinburgh's ill drinkers with a comparison to wider alcohol sales in Scotland

    2011-01-01

    Aim To compare alcohol purchasing and consumption by ill drinkers in Edinburgh with wider alcohol sales in Scotland. Design Cross-sectional. Setting Two hospitals in Edinburgh in 2008/09. Participants A total of 377 patients with serious alcohol problems; two-thirds were in-patients with medical, surgical or psychiatric problems due to alcohol; one-third were out-patients. Measurements Last week's or typical weekly consumption of alcohol: type, brand, units (1 UK unit 8 g ethanol), purchase place and price. Findings Patients consumed mean 197.7 UK units/week. The mean price paid per unit was £0.43 (lowest £0.09/unit) (£1 = 1.6 US$ or 1.2€), which is below the mean unit price, £0.71 paid in Scotland in 2008. Of units consumed, 70.3% were sold at or below £0.40/unit (mid-range of price models proposed for minimum pricing legislation by the Scottish Government), and 83% at or below £0.50/unit proposed by the Chief Medical Officer of England. The lower the price paid per unit, the more units a patient consumed. A continuous increase in unit price from lower to higher social status, ranked according to the Scottish Index of Multiple Deprivation (based on postcode), was not seen; patients residing in postcodes in the mid-quintile paid the highest price per unit. Cheapness was quoted commonly as a reason for beverage choice; ciders, especially ‘white’ cider, and vodka were, at off-sales, cheapest per unit. Stealing alcohol or drinking alcohol substitutes was only very rarely reported. Conclusions Because patients with serious alcohol problems tend to purchase very cheap alcohol, elimination of the cheapest sales by minimum price or other legislation might reduce their consumption. It is unknown whether proposed price legislation in Scotland will encourage patients with serious alcohol problems to start stealing alcohol or drinking substitutes or will reduce the recruitment of new drinkers with serious alcohol problems and produce predicted longer-term gains in

    Introduction Despite strong evidence that increasing alcohol taxes reduces alcohol-related harm, state alcohol taxes have declined in real terms during the past 3 decades. Opponents of tax increases argue that they are unfair to “responsible” drinkers and those who are financially disadvantaged. The objectives of this study were to assess the impact of hypothetical state alcohol tax increases on the cost of alcohol for adults in the United States on the basis of alcohol consumption and sociodemographic characteristics. Methods The increased net cost of alcohol (ie, product plus tax) from a series of hypothetical state alcohol tax increases was modeled for all 50 states using data from the 2011 Behavioral Risk Factor Surveillance System, IMPACT Databank, and the Alcohol Policy Information System. Costs were assessed by drinking pattern (excessive vs nonexcessive) and by sociodemographic characteristics. Results Among states, excessive drinkers would pay 4.8 to 6.8 times as much as nonexcessive drinkers on a per capita basis and would pay at least 72% of aggregate costs. For nonexcessive drinkers, the annual cost from even the largest hypothetical tax increase ($0.25 per drink) would average less than $10.00. Drinkers with higher household incomes and non-Hispanic white drinkers would pay higher per capita costs than people with lower incomes and racial/ethnic minorities. Conclusion State-specific tax increases would cost more for excessive drinkers, those with higher incomes, and non-Hispanic whites. Costs to nonexcessive drinkers would be modest. Findings are relevant to developing evidence-based public health practice for a leading preventable cause of death. PMID:27197080

    The negative impact of alcohol is a significant concern to the US military given the costs associated with alcohol-related offenses. Despite considerable research in active duty personnel, relatively little is known about the current extent of alcohol use among incoming recruits. We examined the history of alcohol use and harmful patterns of alcohol consumption among recruits entering the United States Air Force (USAF; N=50,549) over the span of 4 years (2010-2014). Across all years, drinking rates reflected national average trends for those aged 18-24 (NIDA, 2014). However, when abstainers were excluded, those under 21 (n=10,568) reported an average of 18.4 drinks per week, whereas those age 21 and over (n=14,188) reported an average of 14.1 drinks per week, suggesting that for those who drink, those under 21 are exhibiting more risky drinking rates. Alcohol Use Disorders Identification Task (AUDIT) scores for drinkers reflected these same trends. For those under 21, 58% scored in risk categories of 2 or higher (risky drinking warranting attention), compared with 40% for those age 21 and over. These scores indicate that for recruits in the USAF, approximately half report alcohol use immediately prior to basic training, resulting in the inheritance of these potential alcohol related issues for those conducting training of these recruits. Based upon these numbers, brief alcohol interventions could have a potential positive impact on individuals in their initial training stages of the USAF to prevent these baseline issues from resulting in problems later in their military careers.

    Greater access to alcohol has been widely found to be associated with many negative outcomes including violence perpetration. This study examines the relationship between alcohol outlet density, alcohol use, and intimate partner violence (IPV) victimization among young women in the United States. A direct association between alcohol outlet density in one's neighborhood and the likelihood of IPV victimization was examined. Data were from Wave III of the National Longitudinal Study of Adolescent Health (Add Health), which followed a nationally representative sample of adolescents into adulthood. Participants were young adult females age 18 to 26 at Wave III. Of the 4,571 female respondents who reported a current heterosexual relationship and had IPV data, 13.2% reported having been the victim of physical violence only and 6.5% experienced sexual only or physical and sexual violence in the relationship during the past year. In the regression models tested, there was no significant direct association between neighborhood alcohol outlet density and IPV victimization nor was there an association between outlet density and drinking behaviors, thus eliminating the possibility of an indirect association. Results of fully adjusted models indicate females who drank heavily, whether infrequently or frequently, were at significant risk for experiencing sexual only IPV or sexual and physical IPV. Asians and Native Americans were at significantly greater odds of experiencing sexual only or sexual and physical IPV compared with non-Hispanic Whites, while non-Hispanic Blacks were at significantly greater odds for physical only IPV. We conclude that a continuous measure of alcohol outlet density was not associated with IPV in models controlling for individual and other neighborhood characteristics. Young women who drink heavily, whether infrequently or frequently, have greater odds of experiencing sexual only or sexual and physical compared to abstainers. Similar to previous study

    Background Alcoholic hepatitis (AH) is a major cause of liver-related hospitalization. The profile, treatment patterns, and outcomes of subjects admitted for AH in routine clinical practice are unknown. Also, it is not known whether these are changing over time. This study is thus aimed to identify temporal trends in hospitalization rates, clinical characteristics, treatment patterns, and outcomes of subjects admitted for AH in a routine clinical setting. Methods A retrospective analysis of adults admitted for AH from 2000 to 2011 was performed using an anonymized EMR database of patient-level data from 169 U.S. medical centers. Results (i) Epidemiology: The proportion of baby boomers admitted for AH increased from 2000 to 2011 (26 to 31%, p < 0.0001). (ii) Clinical: The median Model for End-Stage Liver Disease (MELD) score increased over time from 12 to 14 (p = 0.0014) driven mainly by increased international normalized ratio (1.2 to 1.4, p < 0.0001). The median Charlson Comorbidity Index increased from 0 to 1 (p < 0.0001) with increased diabetes, chronic obstructive pulmonary disease, and heart disease. (iii) Complications: The following increased from 2001 to 2011: Gastrointestinal bleed—7 to 10% (p = 0.03); hepatic encephalopathy—7 to 13% (p < 0.0001); hepatorenal syndrome—1.8 to 2.8% (p = 0.0003); sepsis—0 to 6% (p < 0.0001); and pancreatitis—11 to 16% (p = 0.0061). (iv) Treatment patterns and mortality: Eight to 9% of subjects received steroids while pentoxifylline use increased to 2.2%. In those with MELD ≥ 22, mortality remained between 19 and 20% and only steroids modestly improved survival in this subset. Conclusions Severe AH continues to have a high mortality. The severity and comorbidities and complications associated with AH have worsened. Drug therapy remains suboptimal. PMID:27147285

    Background US-born Latinos have higher rates of alcohol use than Latinos who have immigrated to the United States. However, little is known about the pre-immigration drinking patterns of Latino immigrants or about the changes in their drinking behaviors in the 2 years post-immigration. Objectives This article reports findings of a longitudinal study that compared rates of regular, binge, and heavy drinking among a cohort of recent Latino immigrants, ages 18–34, prior to immigration to the United States and in the 2 years post-immigration. Methods Baseline data were collected on the drinking patterns of 405 Latino immigrants living in the United States for 12 months or less. A follow-up assessment occurred during their second year in the United States. Results Findings indicate that number of days of drinking declined significantly post-immigration. Binge alcohol use (five or more drinks on the same occasion during the past 90 days) significantly declined during the post-immigration period. Heavy alcohol use (five or more drinks on the same occasion on five or more days during the past 90 days) also significantly decreased. Conclusions Results suggest a need for continued exploration of pre-immigration drinking patterns and research to uncover underlying factors associated with declines in rates of problematic alcohol use among recent Latino immigrants. Scientific Significance The results of this study can aid in furthering our understanding of the alcohol use of Latino immigrants ages 18–34 prior to and post immigration to the United States to guide future research and the development of culturally tailored clinical interventions.

    Excessive alcohol use is risk factor for a wide range of health and social problems including liver cirrhosis, certain cancers, depression, motor vehicle crashes, and violence. Alcohol use during pregnancy can lead to fetal alcohol spectrum disorders (FASDs) and other adverse birth outcomes . Community studies estimate that as many as 2% to 5% of first grade students in the United States might have an FASD, which include physical, behavioral, or learning impairments. In 2005, the Surgeon General reissued an advisory urging women who are or might be pregnant to abstain from alcohol consumption to eliminate the risk for FASDs or other negative birth outcomes. To estimate current prevalences of any alcohol use and binge drinking (consuming four or more drinks on an occasion) among pregnant and nonpregnant women aged 18-44 years in the United States, CDC analyzed 2011-2013 Behavioral Risk Factor Surveillance System (BRFSS) data. Among pregnant women, the prevalences of any alcohol use and binge drinking in the past 30 days were 10.2% and 3.1%, respectively. Among nonpregnant women, the prevalences of any alcohol use and binge drinking in the past 30 days were 53.6% and 18.2%, respectively. Among binge drinkers, pregnant women reported a significantly higher frequency of binge drinking than nonpregnant women (4.6 and 3.1 episodes, respectively); the largest amount consumed during binge drinking was also higher among pregnant women than nonpregnant women (7.5 versus 6.0 drinks), although this difference was not statistically significant. Implementation of evidence-based clinical and community-level strategies would be expected to reduce binge drinking among pregnant women and women of childbearing age, and any alcohol consumption among women who are or might be pregnant. Healthcare professionals can support these efforts by implementing alcohol screening and brief interventions in their primary care practices, and informing women that there is no known safe level of

    Summary Background Several countries are considering a minimum price policy for alcohol, but concerns exist about the potential effects on drinkers with low incomes. We aimed to assess the effect of a £0·45 minimum unit price (1 unit is 8 g/10 mL ethanol) in England across the income and socioeconomic distributions. Methods We used the Sheffield Alcohol Policy Model (SAPM) version 2.6, a causal, deterministic, epidemiological model, to assess effects of a minimum unit price policy. SAPM accounts for alcohol purchasing and consumption preferences for population subgroups including income and socioeconomic groups. Purchasing preferences are regarded as the types and volumes of alcohol beverages, prices paid, and the balance between on-trade (eg, bars) and off-trade (eg, shops). We estimated price elasticities from 9 years of survey data and did sensitivity analyses with alternative elasticities. We assessed effects of the policy on moderate, hazardous, and harmful drinkers, split into three socioeconomic groups (living in routine or manual households, intermediate households, and managerial or professional households). We examined policy effects on alcohol consumption, spending, rates of alcohol-related health harm, and opportunity costs associated with that harm. Rates of harm and costs were estimated for a 10 year period after policy implementation. We adjusted baseline rates of mortality and morbidity to account for differential risk between socioeconomic groups. Findings Overall, a minimum unit price of £0·45 led to an immediate reduction in consumption of 1·6% (−11·7 units per drinker per year) in our model. Moderate drinkers were least affected in terms of consumption (−3·8 units per drinker per year for the lowest income quintile vs 0·8 units increase for the highest income quintile) and spending (increase in spending of £0·04 vs £1·86 per year). The greatest behavioural changes occurred in harmful drinkers (change in consumption of −3·7% or

    Corporate actors seek to influence alcohol policies through various means, including attempts to shape the evidential content of policy debates. In this case study, we examined how SABMiller engaged the think tank Demos to produce reports on binge drinking, which were heavily promoted among policymakers at crucial stages in the development of the UK government’s 2012 alcohol strategy. One key report coincided with other SABMiller-funded publications, advocating measures to enhance parenting as an alternative to minimum unit pricing. In this instance, the perceived independence of an influential think tank was used to promote industry interests in tactics similar to those of transnational tobacco corporations. This approach is in keeping with other alcohol industry efforts to marginalize the peer-reviewed literature. PMID:24922137

    An anisotropic united-atom (AUA4) intermolecular potential has been derived for the family of alkanols by first optimizing a set of charges to reproduce the electrostatic potential of the isolated molecules of methanol and ethanol and then by adjusting the parameters of the OH group to fit selected equilibrium properties. In particular, the proposed potential includes additional extra-atomic charges in order to improve the matching to the electrostatic field. Gibbs ensemble Monte Carlo simulations were performed to determine the phase equilibria, while the critical region was explored by means of grand canonical Monte Carlo simulations combined with histogram reweighting techniques. In order to increase the transferability of the model, only the parameters of the Lennard-Jones OH group have been fitted, the parameters of the other AUA groups are taken from previous works. Nevertheless, a good level of agreement was obtained for all compounds considered in this work. In particular, excellent results were obtained for the Henry constants calculation of different gases in alkanols. PMID:18646801

    Alcoholic beverages consumption by adolescents is a global problem with repercussion on different social sectors. However, the reasons that cause this behavior are still little studied. This qualitative research aimed to understand the socially constructed representations of adolescents about the consumption of alcoholic beverages, in a Family Health Unit in the city of Feira de Santana, state of Bahia, Brazil. Subjects were twenty-one adolescents of both genders. Observation, focus groups and semi-structured interviews were used for data collection, followed by interpretation of meanings as data analysis. Results showed that this practice represents "to drink much", which is close to the concept of binge drinking and "to be in the group", evidencing the socializing character of drinking. It also means a rite of passage. Among the factors that influence this representation, adults' attitudes to alcohol, especially the father and media, are highlighted. It is concluded that this substance represents a symbolic capital, with contradictions regarding the issue, precariousness of protective factors and existence of vulnerability factors. Rethinking adolescent-targeted and alcohol-related public policies is needed. PMID:20464186

    Alcohol use typically is initiated during adolescence, an age period that overlaps with critical structural and functional maturation of the brain. Brain maturation and associated improvements in decision-making continue into the second decade of life, reaching plateaus within the period referred to as “emerging adulthood” (18–24 years). Emerging adulthood is the typical age span of the traditionally aged college student, which includes the age (21 years) when alcohol consumption becomes legal in the United States. This review highlights neurobiological evidence indicating the vulnerabilities of the emerging adult brain to alcohol effects. This review also identifies that reduced sensitivity to alcohol sedation and increased sensitivity to alcohol-related disruptions in memory, positive family history of alcoholism effects on brain structure and function, and emerging co-morbid psychiatric conditions serve as unique vulnerabilities that increase the risks associated with underage alcohol use. These vulnerabilities likely contribute to excessive and unsupervised drinking in college students. Discouraging alcohol consumption until neurobiological adulthood is reached is important for minimizing alcohol-related disruptions in brain development and decision-making capacity, and reducing the negative behavioral consequences associated with underage alcohol use.

    Meconium fatty acid ethyl esters (FAEEs) are sensitive and specific biomarkers for prenatal alcohol exposure (PAE) in pregnancy. We recently reported a 2.5% rate of FAEE positive meconium in a general population sample of infants born in the region of Grey-Bruce, Ontario. Women in this region with high-risk pregnancies are transferred to a tertiary care facility in London, Ontario. The objective of this study was to determine, in a population-based sample, whether high-risk pregnancies are associated with an increased risk of in utero alcohol exposure. Grey-Bruce residents transferred to the high-risk obstetric unit of St. Joseph's Health Care in London, Ontario were identified and consented to this anonymous prevalence study. Meconium was collected and analyzed for FAEE using gas chromatography with mass spectrometry. The prevalence of FAEE positive meconium was compared with the population-based prevalence in the Grey-Bruce. Fifty meconium specimens were collected from August 1, 2006 to July 31, 2007. Fifteen (30%) specimens tested positive for FAEE. The results indicate that infants born in the high-risk obstetric unit had a 12-fold higher risk of screening positive for second and third trimester alcohol exposure compared with infants born in the general population of Grey-Bruce (relative risk=12.04, 95% confidence interval=6.40-22.65, P<.0001). These results suggest that the high-risk pregnancies should be screened for PAE and followed-up for potential diagnosis of fetal alcohol spectrum disorder. PMID:20584588

    Organomercurials including methylmercury are ubiquitous environmental pollutants and highly toxic to humans. Now it could be shown that N-methylimidazole based thiones/selones having an N-CH2CH2OH substituent are remarkably effective in detoxifying various organomercurials to produce less toxic HgE (E=S, Se) nanoparticles. Compounds lacking the N-CH2CH2OH substituent failed to produce HgE nanoparticles upon treatment with organomercurials, suggesting that this moiety plays a crucial role in the detoxification by facilitating the desulfurization and deselenization processes. This novel way of detoxifying organomercurials may lead to the discovery of new compounds to treat patients suffering from methylmercury poisoning. PMID:26205242

    Alcohol use and associated alcohol-related harm (ARH) are a prevalent and important public health problem, with alcohol representing about 4% of the global burden of disease. A discussion of ARH secondary to alcohol consumption necessitates a consideration of the amount of alcohol consumed and the drinking pattern. This study examined the association between alcohol drinking patterns and self-reported ARH. Pearson chi-square test (χ2) and logistic regression analyses were used on data from the National Comorbidity Survey Replication (NCS-R). The NCS-R is a cross-sectional nationally representative sample. Data was obtained by face-to-face interviews from 9282 adults aged ≥18 years in the full sample, and 5,692 respondents in a subsample of the full sample. Results presented as odds ratio (OR) and 95% confidence intervals (95% CI). Alcohol drinking patterns (frequency of drinking, and drinks per occasion) were associated with increased risks of self-reported ARH; binge or “risky” drinking was strongly predictive of ARH than other categories of drinks per occasion or frequency of drinking; and men had significantly higher likelihood of ARH in relation to frequency of drinking and drinks per occasion. Findings provide evidence for public health practitioners to target alcohol prevention strategies at the entire population of drinkers. PMID:25057502

    Data from a population-based study of newly diagnosed cases of prostate cancer (n = 362) and age-matched controls (n = 685) conducted in Utah (United States) between 1983 and 1986 were used to determine if cigarette smoking, alcohol, coffee, tea, caffeine, and theobromine were associated with prostate cancer risk. These factors were examined since their use differs in the Utah population, which is comprised predominantly of members of the Church of Jesus Christ of Latter-day Saints (LDS or Mormon), from most other populations. Pack-years of cigarettes smoked, alcohol intake, and consumption of alcohol, coffee, tea, and caffeine were not associated with prostate cancer risk. Compared with men with very low levels of theobromine intake, older men consuming 11 to 20 and over 20 mg of theobromine per day were at increased risk of prostate cancer (odds ratio [OR] for all tumors = 2.06, 95 percent confidence interval [CI] = 1.33-3.20, and OR = 1.47, CI = 0.99-2.19, respectively; OR for aggressive tumors = 1.90, CI = 0.90-3.97, and OR = 1.74, CI = 0.91-3.32, respectively). We present biological mechanisms for a possible association between prostate cancer and theobromine. This finding needs further exploration in studies with a wider range of theobromine exposures and more men with aggressive tumors. PMID:8280834

    Transition metal based nanomaterials have been used in concurrence with Atmospheric Pressure Non Equilibrium Plasma (APNEP) generated using microwaves to detoxify volatile organic compound (VOC) polluted gas streams. Sol-gel synthesized titania nanostructured surfaces using reverse micelles alone or with further surface modification on alumina and cordierite substrate geometries, have been developed. By the construction of a pilot reactor which contains the heterogeneous catalyst after the plasma generation chamber, it was shown that the nanostructured titania greatly enhanced the destruction of the model VOC compounds (Toluene and 1,2 dichlorobenzene) as opposed to the plasma stream alone. Experiments presented show the effect of microwave power, gas stream composition (N2, N2/O2 and N2/H2O) and temperature on the effectiveness of the catalyst. These experimental variables cause a change in the Fermi electron (e-) and electron hole density (h+) of the nanostructured material, therefore, causing enhanced redox VOC destruction to occur on the surface of the nanoparticles. It was observed that the catalyst is greatly enhanced at low microwave plasma power by doping the surface of the nanoparticles with noble metals at low concentrations by chemical vapour deposition (CVD). These results demonstrate that APNEP microwave technology performance is greatly enhanced with the use of nanostructured heterogeneous catalysis for detoxification of VOC polluted gas streams.

    Clinicians who work in the postanesthesia care unit (PACU), operating room (OR), and intensive care unit (ICU) have a greater opportunity to cross-contaminate patients because of high workloads and frequent patient contact events. Much progress has been made to increase hand hygiene compliance with the introduction of alcohol-based wall, bedside, and pocket dispensers. The introduction of body-worn alcohol-based dispensers to anesthesia and ICU providers has been shown to decrease ICU hospital-acquired infections and ventilator-associated pneumonias, and decrease contamination of the anesthesia workplace. Body-worn alcohol-based dispensers are an improvement in ergonomics, especially for those working in high intensity areas. The unit worn on the belt or scrubs waist is readily accessible, can be activated with one hand, and can be a vital tool to close the gap for hand hygiene. PMID:23522268

Methods In 2012, we conducted an online, self-administered survey of a national sample of 1,031 underage drinkers, ages 13-20, to determine the prevalence of past 30-day consumption for each of 898 alcoholic beverage brands, including 62 FABs, and each brand’s youth consumption share, based on the estimated total number of standard drinks consumed. There were three brand-specific outcome measures: prevalence of consumption, prevalence of consumption during heavy episodic drinking, and consumption share, defined as the percentage of the total drinks consumed by all respondents combined that was attributable to a particular brand. Results The FAB brands with the highest prevalence of past 30-day consumption were Smirnoff Malt Beverages, 17.7%; Mike’s, 10.8%; Bacardi Malt Beverages, 8.0%; and Four Loko/Four MaXed, 6.1%. Just five brands accounted for almost half (49.1%) of the total consumption share by volume within the FAB category. Conclusion Flavored alcoholic beverages are highly popular among underage drinkers, and their FAB brand preferences are highly concentrated among a small number of brands. To decrease the consumption of FABs by underage youth, all states should re-classify these beverages as distilled spirits rather than beer. PMID:24266600

    Alcohol consumption patterns and recognition of health outcomes related to hazardous drinking vary widely internationally, raising the question whether these national differences are reflected in brain damage observed in alcoholism. This retrospective analysis assessed variability of alcoholism's effects on brain cerebrospinal fluid (CSF) and white matter volumes between France and the United States (U.S.). MRI data from two French sites (Caen and Orsay) and a U.S. laboratory (SRI/Stanford University) were acquired on 1.5T imaging systems in 287 controls, 165 uncomplicated alcoholics (ALC), and 26 alcoholics with Korsakoff's Syndrome (KS). All data were analyzed at the U.S. site using atlas-based parcellation. Results revealed graded CSF volume enlargement from ALC to KS and white matter volume deficits in KS only. In ALC from France but not the U.S., CSF and white matter volumes correlated with lifetime alcohol consumption, alcoholism duration, and length of sobriety. MRI highlighted CSF volume enlargement in both ALC and KS, serving as a basis for an ex vacuo process to explain correlated gray matter shrinkage. By contrast, MRI provided a sensitive in vivo biomarker of white matter volume shrinkage in KS only, suggesting a specific process sensitive to mechanisms contributing to Wernicke's encephalopathy, the precursor of KS. Identified structural brain abnormalities may provide biomarkers underlying alcoholism's heterogeneity in and among nations and suggest a substrate of gray matter tissue shrinkage. Proposed are hypotheses for national differences in interpreting whether the severity of sequelae observe a graded phenomenon or a continuum from uncomplicated alcoholism to alcoholism complicated by KS.

    Background In the United Kingdom (UK), there is an extensive market for the class 'A' drug heroin. Many heroin users spend time in prison. People addicted to heroin often require prescribed medication when attempting to cease their drug use. The most commonly used detoxification agents in UK prisons are buprenorphine, dihydrocodeine and methadone. However, national guidelines do not state a detoxification drug of choice. Indeed, there is a paucity of research evaluating the most effective treatment for opiate detoxification in prisons. This study seeks to address the paucity by evaluating routinely used interventions amongst drug using prisoners within UK prisons. Methods/Design The Leeds Evaluation of Efficacy of Detoxification Study (LEEDS) Prisons Pilot Study will use randomised controlled trial methodology to compare the open use of buprenorphine and dihydrocodeine for opiate detoxification, given in the context of routine care, within HMP Leeds. Prisoners who are eligible and give informed consent will be entered into the trial. The primary outcome measure will be abstinence status at five days post detoxification, as determined by a urine test. Secondary outcomes during the detoxification and then at one, three and six months post detoxification will be recorded. PMID:17210080

    Underage alcohol use is a global public health problem and alcohol advertising has been associated with underage drinking. The alcohol industry regulates itself and is the primary control on alcohol advertising in many countries around the world, advising trade association members to advertise only in adult-oriented media. Despite high levels of compliance with these self-regulatory guidelines, in several countries youth exposure to alcohol advertising on television has grown faster than adult exposure. In the United States, we found that exposure for underage viewers ages 18-20 grew from 2005 through 2011 faster than any adult age group. Applying a method adopted from a court in the US to identify underage targeting of advertising, we found evidence of targeting of alcohol advertising to underage viewers ages 18-20. The court's rule appeared in Lockyer v. Reynolds (The People ex rel. Bill Lockyer v. R.J. Reynolds Tobacco Company, GIC764118, 2002). We demonstrated that alcohol companies were able to modify their advertising practices to maintain current levels of adult advertising exposure while reducing youth exposure. PMID:24424494

    Rapid Opiate Detoxification under Anesthesia (RODA) involves the use of opiate antagonists combined with anesthesia and pharmacotherapy to reduce withdrawal symptoms. The aim of our study was to measure the plasma concentrations of heroin metabolites and methadone during anesthesia and patient stay at the hospital in order to assess the amount of active substances at each protocol step. Plasma concentrations of antagonists were also quantified and compared to the recommended target values. Blood samples were drawn in 10 patients undergoing RODA at different times of the procedure (during anesthesia, in post-anesthesia care unit and in psychiatry unit). The plasma concentrations of heroin metabolites, methadone and antagonists were measured using a previously described method. Heroin active metabolites were no longer detected in the patient blood when helshe left the hospital; by contrast, methadone was still present at significant concentrations 3 days after the beginning of the detoxification procedure. Naltrexone analysis allowed us to adjust doses to insure opiate receptor blockade during acute withdrawal, which is a critical period. PMID:23888580

    Objective To evaluate the potential impact of two alcohol control policies under consideration in England: banning below cost selling of alcohol and minimum unit pricing. Design Modelling study using the Sheffield Alcohol Policy Model version 2.5. Setting England 2014-15. Population Adults and young people aged 16 or more, including subgroups of moderate, hazardous, and harmful drinkers. Interventions Policy to ban below cost selling, which means that the selling price to consumers could not be lower than tax payable on the product, compared with policies of minimum unit pricing at £0.40 (€0.57; $0.75), 45p, and 50p per unit (7.9 g/10 mL) of pure alcohol. Main outcome measures Changes in mean consumption in terms of units of alcohol, drinkers’ expenditure, and reductions in deaths, illnesses, admissions to hospital, and quality adjusted life years. Results The proportion of the market affected is a key driver of impact, with just 0.7% of all units estimated to be sold below the duty plus value added tax threshold implied by a ban on below cost selling, compared with 23.2% of units for a 45p minimum unit price. Below cost selling is estimated to reduce harmful drinkers’ mean annual consumption by just 0.08%, around 3 units per year, compared with 3.7% or 137 units per year for a 45p minimum unit price (an approximately 45 times greater effect). The ban on below cost selling has a small effect on population health—saving an estimated 14 deaths and 500 admissions to hospital per annum. In contrast, a 45p minimum unit price is estimated to save 624 deaths and 23 700 hospital admissions. Most of the harm reductions (for example, 89% of estimated deaths saved per annum) are estimated to occur in the 5.3% of people who are harmful drinkers. Conclusions The ban on below cost selling, implemented in the England in May 2014, is estimated to have small effects on consumption and health harm. The previously announced policy of a minimum unit price, if set at

    Objectives. We investigated tobacco companies’ knowledge about concurrent use of tobacco and alcohol, their marketing strategies linking cigarettes with alcohol, and the benefits tobacco companies sought from these marketing activities. Methods. We performed systematic searches on previously secret tobacco industry documents, and we summarized the themes and contexts of relevant search results. Results. Tobacco company research confirmed the association between tobacco use and alcohol use. Tobacco companies explored promotional strategies linking cigarettes and alcohol, such as jointly sponsoring special events with alcohol companies to lower the cost of sponsorships, increase consumer appeal, reinforce brand identity, and generate increased cigarette sales. They also pursued promotions that tied cigarette sales to alcohol purchases, and cigarette promotional events frequently featured alcohol discounts or encouraged alcohol use. Conclusions. Tobacco companies’ numerous marketing strategies linking cigarettes with alcohol may have reinforced the use of both substances. Because using tobacco and alcohol together makes it harder to quit smoking, policies prohibiting tobacco sales and promotion in establishments where alcohol is served and sold might mitigate this effect. Smoking cessation programs should address the effect that alcohol consumption has on tobacco use. PMID:21852637

    This paper analyzes what portion of US nonfatal crashes are alcohol-involved and how well police and hospitals detect involvement. A capture recapture model estimated alcohol involvement from levels detected by police and hospitals and the extent of detection overlap. We analyzed 550,933 Crash Outcome Data Evaluation System driver records from 2006–2008 police crash report censuses probabilistically linked to hospital inpatient and emergency department (ED) discharge censuses for CT, KY (admissions only), MD, NE, NY, SC, and UT. We computed national estimates from NHTSA’s General Estimates System. Nationally an estimated 7.5% of drivers in nonfatal crashes and 12.9% of nonfatal crashes were alcohol-involved. (Crashes often involve multiple drivers but rarely are two alcohol-involved.) Police correctly identified an estimated 32% of alcohol-involved drivers in non-fatal crashes including 48% in injury crashes. Excluding KY, police in the six states reported 47% of alcohol involvement for cases treated in EDs and released and 39% for admitted cases. In contrast, hospitals reported 28% of involvement for ED cases and 51% for admitted cases. Underreporting varied widely between states. Police reported alcohol involvement for 44% of those who hospitals reported were alcohol-involved, while hospitals reported alcohol involvement for 33% of those who police reported were alcohol-involved. Police alcohol reporting completeness rose with police-reported driver injury severity. At least one system reported 62% of alcohol involvement. Police and hospitals need to communicate better about alcohol involvement. Despite the proven effectiveness of brief alcohol intervention, EDs rarely detect, much less intervene with crash-involved drinking drivers. Both police and EDs particularly need to assess alcohol involvement in minor injury better. PMID:23169120

    Life relies on numerous biochemical processes working synergistically and correctly. Certain substances disrupt these processes, inducing living organism into an abnormal state termed intoxication. Managing intoxication usually requires interventions, which is referred as detoxification. Decades of development on detoxification reveals the potential of enzymes as ideal therapeutics and antidotes, because their high substrate specificity and catalytic efficiency are essential for clearing intoxicating substances without adverse effects. However, intrinsic shortcomings of enzymes including low stability and high immunogenicity are major hurdles, which could be overcome by delivering enzymes with specially designed nanocarriers. Extensive investigations on protein delivery indicate three types of enzyme-nanocarrier architectures that show more promise than others for systemic detoxification, including liposome-wrapped enzymes, polymer-enzyme conjugates, and polymer-encapsulated enzymes. This review highlights recent advances in these nano-architectures and discusses their applications in systemic detoxifications. Therapeutic potential of various enzymes as well as associated challenges in achieving effective delivery of therapeutic enzymes will also be discussed. PMID:25980935

    Introduction Excessive alcohol consumption is a leading cause of premature mortality in the United States. The objectives of this study were to update national estimates of alcohol-attributable deaths (AAD) and years of potential life lost (YPLL) in the United States, calculate age-adjusted rates of AAD and YPLL in states, assess the contribution of AAD and YPLL to total deaths and YPLL among working-age adults, and estimate the number of deaths and YPLL among those younger than 21 years. Methods We used the Centers for Disease Control and Prevention’s Alcohol-Related Disease Impact application for 2006–2010 to estimate total AAD and YPLL across 54 conditions for the United States, by sex and age. AAD and YPLL rates and the proportion of total deaths that were attributable to excessive alcohol consumption among working-age adults (20-64 y) were calculated for the United States and for individual states. Results From 2006 through 2010, an annual average of 87,798 (27.9/100,000 population) AAD and 2.5 million (831.6/100,000) YPLL occurred in the United States. Age-adjusted state AAD rates ranged from 51.2/100,000 in New Mexico to 19.1/100,000 in New Jersey. Among working-age adults, 9.8% of all deaths in the United States during this period were attributable to excessive drinking, and 69% of all AAD involved working-age adults. Conclusions Excessive drinking was responsible for 1 in 10 deaths among working-age adults in the United States. AAD rates vary across states, but excessive drinking remains a leading cause of premature mortality nationwide. Strategies recommended by the Community Preventive Services Task Force can help reduce excessive drinking and harms related to it. PMID:24967831

    Some individuals hospitalized for alcohol or drug detoxification leave against medical advice (AMA). We hypothesized that certain characteristics would be associated with AMA discharges. A case-control study of 1,426 hospital admissions for detoxification (representing 1,080 individuals) was conducted to compare patients leaving the hospital AMA (n=231) with a random sample of those completing detoxification (n=286). Latino ethnicity, detoxification from drugs, Friday or Saturday discharge, Medicaid or no health insurance, and not being treated by one specific attending physician were characteristics associated with an AMA discharge in a backward logistic regression model. Although 85% of the patients with all these characteristics left AMA, only one patient, without any of these five characteristics, did so. We conclude that clinicians can use certain clinical features to predict AMA discharge. Additional research could evaluate if treatment strategies that consider these ethnic and socioeconomic disparities may reduce rates of AMA discharge. PMID:16597577

    Motor vehicle accidents are the leading cause of death among youths and young adults aged 16-25 years in the United States (1). The prevalence of drinking and driving among high school students aged 16-19 years has declined by 54%, from 22.3% in 1991 to 10.3% in 2011 (2). However, the prevalence of weekend nighttime driving under the influence of marijuana (based on biochemical assays) among drivers aged ≥16 years has increased by 48%, from 8.6% in 2007 to 12.6% in 2013-2014 (3). Use of marijuana alone and in combination with alcohol has been shown to impair driving abilities (4-9). This report provides the most recent self-reported national estimates of driving under the influence of alcohol, marijuana, and alcohol and marijuana combined among persons aged 16-25 years, using data from the Substance Abuse and Mental Health Services Administration (SAMHSA) National Survey on Drug Use and Health (NSDUH) from 2002-2014. Prevalence data on driving under the influence of both substances were examined for two age groups (16-20 years and 21-25 years) and by sex and race/ethnicity. During 2002-2014, the prevalence of driving under the influence of alcohol alone significantly declined by 59% among persons aged 16-20 years (from 16.2% in 2002 to 6.6% in 2014; p<0.001) and 38% among persons 21-25 years (from 29.1% in 2002 to 18.1% in 2014; p<0.001). In addition, the prevalence of driving under the influence of alcohol and marijuana combined significantly declined by 39%, from 2.3% in 2002 to 1.4% in 2014 (p<0.001) among persons aged 16-20 years and from 3.1% in 2002 to 1.9% in 2014 (p<0.001) among persons aged 21-25 years. The prevalence of driving under the influence of marijuana alone declined 18%, from 3.8% in 2002 to 3.1% in 2014 (p = 0.05) only among persons aged 16-20 years.

    Little attention has been paid to alcohol use by children aged 12 and younger. The present article summarizes findings on the prevalence of alcohol use from US national and statewide surveys of children in grades 6 and younger based on reports located in searches of the literature and the Internet. Four national surveys and seven statewide surveys of children's alcohol and drug use were located that present rates of lifetime sipping and tasting, lifetime experience of more than a sip, alcohol use in the past year, use in the past month, and use in the past week. Prevalence rates decrease with the level of involvement assessed. Alcohol use increases with age, doubling between grades four and six, with the largest jump in prevalence between grades five and six. At each grade level, boys are more likely to have used alcohol than girls. African-American children are nearly as likely as white and Hispanic children to have used alcohol. Over the past decade or so, the prevalence of both lifetime and current alcohol use has been declining in children. The failure to assess intensity of children's use hampers evaluation of the level of risk experienced by children. There is a need for ongoing nationwide surveillance of alcohol use in this population and for greater education of parents regarding the dangers of introducing children to alcohol use. PMID:17629790

People addicted to heroin often require prescribed medication when attempting to cease their drug use. The most commonly used detoxification agents in UK prisons are currently buprenorphine and methadone, both are recommended by national clinical guidelines. However, these agents have never been compared for opiate detoxification in the prison estate and there is a general paucity of research evaluating the most effective treatment for opiate detoxification in prisons. This study seeks to address this paucity by evaluating the most routinely used interventions amongst drug users within UK prisons. Methods/Design This study uses randomised controlled trial methodology to compare the open use of buprenorphine and methadone for opiate detoxification, given in the context of routine care, within three UK prisons. Prisoners who are eligible and give informed consent will be entered into the trial. The primary outcome will be abstinence status eight days after detoxification, as determined by a urine test.

    New building units (unimers) for metallo-supramolecular polymers 2,5-bis(2,2':6',2''-terpyridine-4'-yl)thiophene, M, and 5,5'-bis(2,2':6',2''-terpyridine-4'-yl)(2,2'-bithiophene), B, with ionic groups attached to thiophene rings are prepared by the modification of corresponding bromo-precursors and assembled with Zn(2+) and Fe(2+) ions into alcohol-soluble conjugated constitutional-dynamic polyelectrolytes (polyelectrolyte dynamers). Ionization of side groups only slightly affects the absorption spectra of unimers as well as dynamers but dramatically changes their solubility. Cyclic conformations of unimer molecules resulting from intramolecular interactions between tpy end-groups and cationic or polar (-CH2Br) side groups are proposed to explain the spectral conformity of the M- and B-type unimers and their dynamers and also inhibition of the ionization reaction with tpy end-groups. The absorption spectra and excitation profiles of Raman spectra show that mainly the red arm of the metal-to-ligand charge transfer band of Fe-dynamers is significantly contributed with transitions involving thiophene rings. The constitutional dynamics of Zn-dynamers is fast while that of Fe-dynamers is so slow that it allows effective separation of the dynamer to fractions in SEC columns. Electronic spectra and viscosity measurements proved that excess of Fe(2+) ions results in shortening of the dynamer chains and their end-capping by these ions. PMID:25941777

    Introduction and aims The National Institute for Health Care and Excellence recommend that alcohol screening and brief intervention (ASBI) should be routinely implemented in secondary care. This study used theoretical frameworks to understand how health professionals can be supported to adapt their behaviour and clinical practice. Design and methods Staff training and support was conducted using theoretical frameworks. A 12-week study, delivering ASBI was carried out as part of routine practice in an endoscopy day-unit. Anonymised patient data were collected using the Alcohol Use Disorders Identification Tool (AUDIT) and whether patients received a brief intervention. Staff completed the Shortened Alcohol and Alcohol Problems Perceptions Questionnaire at three time points and took part in a focus group both pre and post study. Results For staff, levels or role adequacy, role legitimacy, motivation to discuss alcohol, security in their role, job satisfaction and commitment to working with patients who drink increased during the time of the study. 1598 individual patients were seen in the department in the timeframe. Of these, 1180 patients were approached (74%); 18% (n=207) of patients were AUDIT positive. Discussion This study has shown that it is possible to reach a high number of patients in a busy hospital out-patient department and deliver ASBI by working with staff using theoretical frameworks for training. Embedding evidence-based public health interventions into routine clinical environments is complex. The social system in which professionals operate requires consideration alongside individual professionals’ real and perceived barriers and facilitators to change. PMID:26834957

    Background Mass media influence public acceptability, and hence feasibility, of public health interventions. This study investigates newsprint constructions of the alcohol problem and minimum unit pricing (MUP). Methods Quantitative content analysis of 901 articles about MUP published in 10 UK and Scottish newspapers between 2005 and 2012. Results MUP was a high-profile issue, particularly in Scottish publications. Reporting increased steadily between 2008 and 2012, matching the growing status of the debate. The alcohol problem was widely acknowledged, often associated with youths, and portrayed as driven by cheap alcohol, supermarkets and drinking culture. Over-consumption was presented as a threat to health and social order. Appraisals of MUP were neutral, with supportiveness increasing slightly over time. Arguments focused on health impacts more frequently than more emotive perspectives or business interests. Health charities and the NHS were cited slightly more frequently than alcohol industry representatives. Conclusion Emphases on efficacy, evidence and experts are positive signs for evidence-based policymaking. The high profile of MUP, along with growing support within articles, could reflect growing appetite for action on the alcohol problem. Representations of the problem as structurally driven might engender support for legislative solutions, although cultural explanations remain common. PMID:25312002

    Aims To test the hypotheses that stronger policy environments are associated with less impaired driving and that driving-oriented and drinking-oriented policy subgroups are independently associated with impaired driving. Design State-level data on 29 policies in 50 states from 2001–2009 were used as lagged exposures in generalized linear regression models to predict self-reported impaired driving. Setting Fifty United States and Washington, D.C. Participants A total of 1,292,245 adults (≥ 18 years old) biennially from 2002–2010. Measures Alcohol Policy Scale scores representing the alcohol policy environment were created by summing policies weighted by their efficacy and degree of implementation by state-year. Past-30-day alcohol-impaired driving from 2002–2010 was obtained from the Behavioral Risk Factor Surveillance System surveys. Findings Higher Alcohol Policy Scale scores are strongly associated with lower state-level prevalence and individual-level risk of impaired driving. After accounting for driving-oriented policies, drinking-oriented policies had a robust independent association with reduced likelihood of impaired driving. Reduced binge drinking mediates the relationship between drinking-oriented policies and impaired driving, and driving-oriented policies reduce the likelihood of impaired driving among binge drinkers. Conclusions Efforts to reduce alcohol-impaired driving should focus on reducing excessive drinking in addition to preventing driving among those who are impaired. PMID:26925185

    The objective of this analysis was to assess the mortality rate and risk factors in adults, with substance dependence, who are not receiving primary medical care (PC). Date and cause of death were identified using the National Death Index data and death certificates for 470 adults without PC over a period of almost 4 years after detailed clinical assessment after detoxification. Factors associated with risk of mortality were determined using stepwise Cox proportional hazards models. Subjects were 76% male, 47% homeless, and 47% with chronic medical illness; 40% reported alcohol, 27% heroin, and 33% cocaine as substance of choice. Median age was 35. During a period of up to 4 years, 27 (6%) subjects died. Median age at death was 39. Causes included: poisoning by any substance (40.9% of deaths), trauma (13%), cardiovascular disease (13.6%), and exposure to cold (9.1%). The age adjusted mortality rate was 4.4 times that of the general population in the same city. Among these individuals without PC in a detoxification unit, risk factors associated with death were the following: drug of choice [heroin: hazard ratio (HR) 6.9 (95% confidence interval (CI) 1.6–31.1]; alcohol: HR 3.7 (95% CI 0.79–16.9) compared to cocaine); past suicide attempt (HR 2.1, 95% CI 0.96–4.5); persistent homelessness (HR 2.4, 95% CI 1.1–5.3); and history of any chronic medical illness (HR 2.1, 95% CI 0.93–4.7). Receipt of primary care was not significantly associated with death (HR 0.85, 95% CI 0.34–2.1). Risk of mortality is high in patients with addictions and risk factors identifiable when these patients seek help from the health care system (i.e., for detoxification) may help identify those at highest risk for whom interventions could be targeted.

    Early liver transplantation (LT) in European centers reportedly improved survival in patients with severe alcoholic hepatitis (AH) not responding to medical therapy. Our aim was to determine if a strategy of early LT for severe AH could be applied successfully in the United States. We reviewed 111 patients with severe AH at our center from January 2012 to January 2015. The primary end point was mortality at 6 months or early LT, with a secondary end point of alcohol relapse after LT. Survival was compared between those receiving early LT and matched patients who did not. Using a process similar to the European trial, 94 patients with severe AH not responding to medical therapy were evaluated for early LT. Overall, 9 (9.6%) candidates with favorable psychosocial profiles underwent early LT, comprising 3% of all adult LT during the study period. The 6-month survival rate was higher among those receiving early LT compared with matched controls (89% vs 11%, p<0.001). Eight recipients are alive at a median of 735 days with 1 alcohol relapse. Early LT for severe AH can achieve excellent clinical outcomes with low impact on the donor pool and low rates of alcohol relapse in highly selected patients in the United States. PMID:26710309

    In contrast to animals, which release the signal molecule sulfide in small amounts from cysteine and its derivates, phototrophic eukaryotes generate sulfide as an essential intermediate of the sulfur assimilation pathway. Additionally, iron-sulfur cluster turnover and cyanide detoxification might contribute to the release of sulfide in mitochondria. However, sulfide is a potent inhibitor of cytochrome c oxidase in mitochondria. Thus, efficient sulfide detoxification mechanisms are required in mitochondria to ensure adequate energy production and consequently survival of the plant cell. Two enzymes have been recently described to catalyze sulfide detoxification in mitochondria of Arabidopsis thaliana, O-acetylserine(thiol)lyase C (OAS-TL C), and the sulfur dioxygenase (SDO) ethylmalonic encephalopathy protein 1 (ETHE1). Biochemical characterization of sulfide producing and consuming enzymes in mitochondria of plants is fundamental to understand the regulatory network that enables mitochondrial sulfide homeostasis under nonstressed and stressed conditions. In this chapter, we provide established protocols to determine the activity of the sulfide releasing enzyme β-cyanoalanine synthase as well as sulfide-consuming enzymes OAS-TL and SDO. Additionally, we describe a reliable and efficient method to purify OAS-TL proteins from plant material. PMID:25747485

  10. Detoxification reactions: relevance to aging

    PubMed Central

    2008-01-01

    It is widely (although not universally) accepted that organismal aging is the result of two opposing forces: (i) processes that destabilize the organism and increase the probability of death, and (ii) longevity assurance mechanisms that prevent, repair, or contain damage. Processes of the first group are often chemical and physico-chemical in nature, and are either inevitable or only under marginal biological control. In contrast, protective mechanisms are genetically determined and are subject to natural selection. Life span is therefore largely dependent on the investment into protective mechanisms which evolve to optimize reproductive fitness. Recent data indicate that toxicants, both environmental and generated endogenously by metabolism, are major contributors to macromolecular damage and physiological dysregulation that contribute to aging; electrophilic carbonyl compounds derived from lipid peroxidation appear to be particularly important. As a consequence, detoxification mechanisms, including the removal of electrophiles by glutathione transferase-catalyzed conjugation, are major longevity assurance mechanisms. The expression of multiple detoxification enzymes, each with a significant but relatively modest effect on longevity, is coordinately regulated by signaling pathways such as insulin/insulin-like signaling, explaining the large effect of such pathways on life span. The major aging-related toxicants and their cognate detoxification systems are discussed in this review. PMID:18547875

    Background Little is known about brand-specific alcohol consumption among underage youth, as existing information is collected at the level of alcoholic beverage type. This study identifies the alcohol brands consumed by a nationally representative sample of underage youth in the U.S. Methods We obtained a national sample of 1,032 underage youth, ages 13–20, using a pre-recruited internet panel maintained by Knowledge Networks. Youth ages 18–20 were recruited directly from the panel via email invitation. Teens ages 13–17 were identified by asking adult panelists to identify a member of their household. The survey assessed the past 30-day consumption of 898 brands of alcohol among 16 alcoholic beverage types, including the frequency and amount of each brand consumed in the past 30 days. Market share for a given brand was calculated by dividing the total number of drinks for that brand in the past 30 days across the entire sample by the total number of drinks for all identified brands. Results The alcohol brands with highest prevalence of past 30-day consumption were Bud Light (27.9%, 95% confidence interval [CI] 23.3%–32.4%), Smirnoff malt beverages (17.0%, 95% CI 12.9%–21.1%), and Budweiser (14.6%, 95% CI 11.0%–18.3%). Brand market share was concentrated in a relatively small number of brands, with the top 25 brands accounting for nearly half of all market share. Conclusions Underage youth alcohol consumption, although spread out over several alcoholic beverage types, is concentrated among a relatively small number of alcohol brands. This finding has important implications for alcohol research, practice, and policy. PMID:23398328

    Aims To examine state alcohol control policy implementation by policy efficacy and intent. Design A descriptive longitudinal analysis of policy implementation. Setting The United States, 1999–2011. Participants Fifty states and the District of Columbia. Measurements Twenty-nine state-level policies were rated based on an implementation rating (IR; range = 0.0–1.0) gathered from the Alcohol Policy Information System, government and industry reports and other sources; and expert judgment about policy efficacy for addressing binge drinking and alcohol-impaired driving among the general population and youth, respectively. Findings On average, implementation of the most effective general population policies did not change [mean IR = 0.366 in 1999; 0.375 in 2011; slope for annual change = 0.001; 95% confidence interval (CI) for the slope −0.001, 0.002]. In contrast, implementation increased over time for less effective policies (mean IR = 0.287 in 1999; 0.427 in 2011; slope for annual change compared with most effective policies = 0.009; slope 95% CI = 0.002–0.007), for youth-oriented policies (mean IR = 0.424 in 1999; 0.511 in 2011; slope for annual change compared with most effective policies = 0.007; slope 95% CI = 0.005–0.009), and for impaired driving policies (mean IR = 0.493 in 1999; 0.608 in 2011; slope for annual change compared with most effective policies = 0.0105; slope 95% CI = 0.007–0.014). Conclusions Implementation of politically palatable state alcohol policies, such as those targeting youth and alcohol-impaired driving, and less effective policies increased during 1999–2011 in the United States, while the most effective policies that may maximally protect public health remained underused.

  14. Youth exposure to alcohol advertising on television--25 markets, United States, 2010.

    PubMed

    2013-11-01

    Excessive alcohol consumption accounted for an estimated 4,700 deaths and 280,000 years of potential life lost among youths aged <21 years each year during 2001-2005. Exposure to alcohol marketing increases the likelihood to varying degrees that youths will initiate drinking and drink at higher levels. By 2003, the alcohol industry voluntarily agreed not to advertise on television programs where >30% of the audience is reasonably expected to be aged <21 years. However, the National Research Council/Institute of Medicine (NRC/IOM) proposed in 2003 that "the industry standard should move toward a 15% threshold for television advertising". Because local media markets might have different age distributions, the Center on Alcohol Marketing and Youth, Johns Hopkins Bloomberg School of Public Health, evaluated the proportion of advertisements that appeared on television programs in 25 local television markets* and resulting youth exposure that exceeded the industry standard (i.e., >30% aged 2-20 years) or the proposed NRC/IOM standard (i.e., >15% aged 12-20 years). Among national television programs with alcohol advertising, placements were assessed for the 10 programs with the largest number of youth viewers within each of four program categories: network sports, network nonsports, cable sports, and cable nonsports (40 total). Of the 196,494 alcohol advertisements that aired on television programs with the largest number of youth viewers in these local markets, placement of 23.7% exceeded the industry threshold and 35.4% exceeded the NRC/IOM threshold. These results indicate that the alcohol industry's self-regulation of its advertising could be improved, and youth exposure to alcohol advertising could be further reduced by adopting and complying with the NRC/IOM standard. In addition, continued public health surveillance would allow for sustained assessment of youth exposure to alcohol advertising and inform future interventions. PMID:24196664

    This study investigated whether underage drinkers with varied media use patterns differentially consume popular brands of alcohol. A survey was conducted with a national online panel of 1,032 underage youth 13-20 years of age who had consumed at least 1 drink in the past 30 days. A latent class analysis identified four distinct media use patterns. Further analyses explored whether these media use groups differentially consumed the most frequently used alcohol brands. The results showed that past 30-day consumption of specific alcohol brands differed significantly across the four media use clusters, even after controlling for sex, race/ethnicity, household income, U.S. geographic region, frequency of parent's alcohol overconsumption, cigarette smoking, and seatbelt use. This study shows that youth use media in different ways, and this differential use is significantly associated with the consumption of specific alcohol brands. The media clusters revealed in this analysis may inform future research about the association between specific alcohol media exposures and individual brand consumption. PMID:25631372

    Because alcohol use typically is initiated during adolescence and young adulthood and may have long-term consequences, the Monitoring the Future (MTF) study annually assesses various measures of alcohol use among 8th-, 10th-, and 12th-grade students. These analyses have found that although alcohol use among these age groups overall has been declining since 1975, levels remain high. Thus, in 2011 about one-quarter of 8th graders, one-half of 10th graders, and almost two-thirds of 12th graders reported drinking alcohol in the month preceding the interview. Binge drinking (i.e., consumption of five or more drinks in a row) was also prevalent. Specific rates of drinking, binge drinking, and getting drunk varied among different student subgroups based on gender and race/ethnicity. The MTF study has also identified numerous factors that influence the risk of alcohol use among adolescents, including parents and peers, school and work, religiosity and community attachment, exercise and sports participation, externalizing behavior and other drug use, risk taking and sensation seeking, well-being, and drinking attitudes and reasons for alcohol use. Drinking during adolescence can have long-term effects on a person’s life trajectory. Therefore, these findings have broad implications for prevention and intervention efforts with this population.

    In vivo detoxification of furfural by the oleaginous yeast, Trichosporon fermentans, under lipid-producing (i.e., nitrogen-limited) conditions was evaluated for the first time. During the initial fermentation phase, furfural was rapidly reduced to furfuryl alcohol, which is more toxic to T. fermentans than furfural. Furfuryl alcohol was subsequently oxidized to furoic acid which has low toxicity to T. fermentans and is the end product of the in vivo detoxification of furfural in this organism. These observations explain how T. fermentans can grow and accumulate lipids in medium containing furfural. They also indicate that strategies to minimize the transient production of furfuryl alcohol could further improve the capacity of the strain to produce lipids from furfural-containing lignocellulosic hydrolysates.

    Brazil's experience in the use of ethyl alcohol, produced from sugar cane, as a motor fuel in the pure form or in the form of a 20 percent additive to gasoline, is examined. The production of ethanol was 4.2 billion liters from 1981 to 1982 and the plan calls for the production of 5.2 billion liters between 1982 and 1983. The total number of motor vehicles in Brazil which operate on pure alcohol reached 900,000 by the end of 1983 and the expenditure of alcohol in them reached 3 billion liters. The expansion of the use of ethanol as a motor fuel must substantially reduce Brazilian expenditures on the import of oil products, improve the use of agricultural resources and increase the labor force in agriculture. An analogous experience is justified for the U.S.A., but sugar beets must serve as the raw material for the production of ethanol in their case.

    Background The alcohol brand preferences of U.S. underage drinkers have recently been identified, but it is not known whether youth are simply mimicking adult brand choices or whether other factors are impacting their preferences. This study is the first to compare the alcohol brand preferences of underage drinkers and adults. Methods We conducted a cross-sectional assessment of youth and adult alcohol brand preferences. A 2012 internet-based survey of a nationally representative sample of 1,032 underage drinkers, ages 13–20, was used to determine the prevalence of past 30-day consumption for each of 898 alcohol brands, and each brand’s youth market share, based on the total number of standard drinks consumed. Data on the brand-specific prevalence of past 30-day or past 7-day consumption among older youth (ages 18–20), adults (ages 21+), and young adults (ages 21–34) was obtained from Gfk MRI’s Survey of the Adult Consumer for the years 2010–12. Overall market shares for each brand, also measured by the total number of standard drinks consumed, were estimated from national data compiled by Impact Databank for the year 2010. Results Although most alcohol brands popular among underage drinkers were also popular among adult drinkers, there were several brands that appeared to be disproportionately consumed by youth. Conclusions This paper provides preliminary evidence that youth do not merely mimic the alcohol brand choices of adults. Further research using data derived from fully comparable data sources is necessary to confirm this finding. PMID:24483601

    Background Minimum unit pricing of alcohol is a novel public health policy with the potential to improve population health and reduce health inequalities. Theories of the policy process may help to understand the development of policy innovation and in turn identify lessons for future public health research and practice. This study aims to explain minimum unit pricing’s development by taking a ‘multiple-lenses’ approach to understanding the policy process. In particular, we apply three perspectives of the policy process (Kingdon’s multiple streams, Punctuated-Equilibrium Theory, Multi-Level Governance) to understand how and why minimum unit pricing has developed in Scotland and describe implications for efforts to develop evidence-informed policymaking. Methods Semi-structured interviews were conducted with policy actors (politicians, civil servants, academics, advocates, industry representatives) involved in the development of MUP (n = 36). Interviewees were asked about the policy process and the role of evidence in policy development. Data from two other sources (a review of policy documents and an analysis of evidence submission documents to the Scottish Parliament) were used for triangulation. Findings The three perspectives provide complementary understandings of the policy process. Evidence has played an important role in presenting the policy issue of alcohol as a problem requiring action. Scotland-specific data and a change in the policy ‘image’ to a population-based problem contributed to making alcohol-related harms a priority for action. The limited powers of Scottish Government help explain the type of price intervention pursued while distinct aspects of the Scottish political climate favoured the pursuit of price-based interventions. Conclusions Evidence has played a crucial but complex role in the development of an innovative policy. Utilising different political science theories helps explain different aspects of the policy process

    Many medicines available over the counter from pharmacies are known to have abuse potential, including diphenhydramine (DPH), an antihistamine with antimuscarinic properties used for the treatment of insomnia. We present a brief review of the literature describing DPH abuse, and report the case of GF, a 56 year old woman who was admitted to an inpatient addictions unit for detoxification from DPH. A literature search revealed five case reports of DPH abuse including a total of six patients, published between 1986 and 2001. All reported cases exhibited features of DSM-IV criteria for substance dependence, and there was an apparent link with antipsychotic usage. GF was treated with antipsychotics, and was using up to thirty 50 mg DPH tablets each day. She described feeling 'good and calm' and 'it stopped the tremors'. GF tolerated a gradual dose reduction schedule, and completed the detoxification programme relatively comfortably. She was discharged from the inpatient detoxification unit as planned, and had not relapsed at six months. The described case report highlights the importance of enquiring about non prescribed medication when taking a drug history. Similarly community pharmacists and GPs should be vigilant to excessive requests for DPH, particularly in patients with a psychotic illness. PMID:18308811

    Gambling opportunities on and near Native American lands have increased in recent decades; yet there is a lack of research examining the patterns of problem gambling and alcohol abuse among Native Americans in the US. Traditional Native American cultural identity may be a protective factor for problem gambling and alcohol abuse among Native Americans. Telephone interviews were conducted with 415 Native American adults aged 18 years and older across the US. The past-year prevalence of gambling among Native Americans is similar to the rate for non-Native Americans in the US (80 vs. 77%). However, Native Americans have over twice the rate of problem gambling as the US sample (18 vs. 8%). Although Native Americans have a lower rate of past-year alcohol use than the US population (47 vs. 68%), they have a somewhat higher rate of alcohol abuse than their US counterparts (5.5 vs. 4.3%). Logistic regression analysis, with problem gambling as the dependent variable, revealed that lower socioeconomic status is significantly associated with an increased odds of problem gambling for Native Americans. Counter to the hypothesis, the higher the score on the Native American orientation, the higher the odds of being a problem gambler. Further, living by the "White way of life" was associated with a decreased odds of being a problem gambler; and perceived gambling convenience was associated with an increased odds of being a problem gambler. None of the Native American factors was significant in predicting alcohol abuse. These findings highlight the need for further investigation into the influence of cultural factors on Native American gambling. PMID:25408467

    Caffeic acid O-methyltransferase (COMT) is a bifunctional enzyme that methylates the 5- and 3-hydroxyl positions on the aromatic ring of monolignol precursors, with a preference for 5-hydroxyconiferaldehyde, on the way to producing sinapyl alcohol. Lignins in COMT-deficient plants contain benzodioxane substructures due to the incorporation of 5-hydroxyconiferyl alcohol (5-OH-CA), as a monomer, into the lignin polymer. The derivatization followed by reductive cleavage method can be used to detect and determine benzodioxane structures because of their total survival under this degradation method. Moreover, partial sequencing information for 5-OH-CA incorporation into lignin can be derived from detection or isolation and structural analysis of the resulting benzodioxane products. Results from a modified derivatization followed by reductive cleavage analysis of COMT-deficient lignins provide evidence that 5-OH-CA cross couples (at its β-position) with syringyl and guaiacyl units (at their O-4-positions) in the growing lignin polymer and then either coniferyl or sinapyl alcohol, or another 5-hydroxyconiferyl monomer, adds to the resulting 5-hydroxyguaiacyl terminus, producing the benzodioxane. This new terminus may also become etherified by coupling with further monolignols, incorporating the 5-OH-CA integrally into the lignin structure. PMID:20427467

    Caffeic acid O-methyltransferase (COMT) is a bifunctional enzyme that methylates the 5- and 3-hydroxyl positions on the aromatic ring of monolignol precursors, with a preference for 5-hydroxyconiferaldehyde, on the way to producing sinapyl alcohol. Lignins in COMT-deficient plants contain benzodioxane substructures due to the incorporation of 5-hydroxyconiferyl alcohol (5-OH-CA), as a monomer, into the lignin polymer. The derivatization followed by reductive cleavage method can be used to detect and determine benzodioxane structures because of their total survival under this degradation method. Moreover, partial sequencing information for 5-OH-CA incorporation into lignin can be derived from detection or isolation and structural analysis of the resulting benzodioxane products. Results from a modified derivatization followed by reductive cleavage analysis of COMT-deficient lignins provide evidence that 5-OH-CA cross couples (at its beta-position) with syringyl and guaiacyl units (at their O-4-positions) in the growing lignin polymer and then either coniferyl or sinapyl alcohol, or another 5-hydroxyconiferyl monomer, adds to the resulting 5-hydroxyguaiacyl terminus, producing the benzodioxane.

    Alcohol use disorders present a significant public health problem in France and the United States (U.S.), but whether the untoward effect of alcohol on the brain results in similar damage in both countries remains unknown. Accordingly, we conducted a retrospective collaborative investigation between two French sites (Caen and Orsay) and a U.S. laboratory (SRI/Stanford University) with T1-weighted, structural MRI data collected on a common imaging platform (1.5T, General Electric) on 288 normal controls (NC), 165 uncomplicated alcoholics (ALC), and 26 patients with alcoholic Korsakoff's syndrome (KS) diagnosed at all sites with a common interview instrument. Data from the two countries were pooled, then preprocessed and analyzed together at the U.S. site using atlas-based parcellation. National differences indicated that thalamic volumes were smaller in ALC in France than the U.S. despite similar alcohol consumption levels in both countries. By contrast, volumes of the hippocampus, amygdala, and cerebellar vermis were smaller in KS in the U.S. than France. Estimated amount of alcohol consumed over a lifetime, duration of alcoholism, and length of sobriety were significant predictors of selective regional brain volumes in France and in the U.S. The common analysis of MRI data enabled identification of discrepancies in brain volume deficits in France and the U.S. that may reflect fundamental differences in the consequences of alcoholism on brain structure between the two countries, possibly related to genetic or environmental differences.

    Background There has been insufficient research attention to alcohol industry methods of influencing public policies. With the exception of the tobacco industry, there have been few studies of the impact of corporate lobbying on public health policymaking more broadly. Methods We summarize here findings from documentary analyses and interview studies in an integrative review of corporate efforts to influence UK policy on minimum unit pricing (MUP) of alcohol 2007–10. Results Alcohol producers and retailers adopted a long-term, relationship-building approach to policy influence, in which personal contacts with key policymakers were established and nurtured, including when they were not in government. The alcohol industry was successful in achieving access to UK policymakers at the highest levels of government and at all stages of the policy process. Within the United Kingdom, political devolution and the formation for the first time of a Scottish National Party (SNP) government disrupted the existing long-term strategy of alcohol industry actors and created the conditions for evidence-based policy innovations such as MUP. Conclusions Comparisons between policy communities within the United Kingdom and elsewhere are useful to the understanding of how different policy environments are amenable to influence through lobbying. Greater transparency in how policy is made is likely to lead to more effective alcohol and other public policies globally by constraining the influence of vested interests. PMID:24261642

    Aliphatic alcohols (C1 - C4), aldehydes (C1 - C2) and ketones (C3 - C4) have been determined at Tucson, Arizona, and at two rural sites about 40 km distant. Acetonitrile was also measured at the rural sites. The method involved condensation sampling, condensate preconcentration, and gas chromatography. Henry's law coefficients were required for all components and were determined. Mean concentrations in Tucson were higher than those in the rural areas by factors typically between 2 and 8; urban formaldehyde was only slightly elevated. Mean alcohol concentrations ranged from 7.9 ppb (C1) to 0.12 ppb (C4) within the city and from 2.6 ppb (C1) to 0.06 ppb (C4) at the rural sites. Acetone was found at 12 ppb in the city and 2.8 ppb at the rural sites. Concentrations of butanone were a factor of 5 lower. Acetaldehyde, at 23 ppb (city) and 6.9 ppb (rural), far exceeded formaldehyde concentrations (1.8 ppb in the city, and 1.5 ppb at the rural sites). Acetonitrile was found at the rural sites at a mean concentration of 60 ppt. A dimensionless Henry's law coefficient (mol L-1 of liquid/mol L-1 of vapor) was suprisingly similar for the alcohols at 0°C, ranging between 2×104 and 3.4×104 (900-1500 mol L-1 atm-1) the ketones were a factor of 10 lower. For acetaldehyde the coefficient was 1.7×103 (76 mol L-1 atm-1) and for acetonitrile 3.7×103 (165 mol L-1 atm-1). Concentrations of oxygenated organics in the condensates and in precipitation were compared; it was tentatively concluded that concentration differences of the carbonyls were consistent with these species being produced within the cloud, for example, by aqueous photochemistry.

    Objective: We identified associations between time spent watching television and time spent playing video or computer games or using computers and involvement in interpersonal violence, alcohol and drug use in a nationally representative sample of United States high school students. Methods: We analyzed data from the 2007 national Youth Risk Behavior Survey. Exposure variables were time spent watching television and time spent playing computer or video games or using computers (hereafter denoted as “computer/video game use”) on an average school day; outcome variables included multiple measures assessing involvement in violence and alcohol or drug use. Chi-square tests were used to identify statistically significant associations between each exposure variable and each of the outcome variables. We used logistic regression to obtain crude odds ratios for outcome variables with a significant chi-square p-value and to obtain adjusted odds ratios controlling for sex, race, and grade in school. Results: Overall, 35.4% (95% CI=33.1%–37.7%) of students reported frequent television (TV) use and 24.9% (95% CI=22.9%–27.0%) reported frequent computer/video game use. A number of risk behaviors, including involvement in physical fights and initiation of alcohol use before age 13, were significantly associated with frequent TV use or frequent computer/video game use, even after controlling for sex, race/ethnicity and grade. Conclusion: Findings highlight the need for additional research to better understand the mechanisms by which electronic media exposure and health-risk behaviors are associated and for the development of strategies that seek to understand how the content and context (e.g., watching with peers, having computer in common area) of media use influence risk behaviors among youth.

    Little is known about the nature and extent of alcohol and other drug (AOD) use among pregnant women in Cape Town, South Africa, despite the very high levels of AOD use in this part of the country. A cross-sectional survey was conducted among pregnant women attending 11 Midwife Obstetric Units (MOUs) in greater Cape Town. A two-stage cluster survey design was used. In total, 5231 pregnant women were screened to assess self-reported prevalence estimates. Of these, 684 (13.1%) were intentionally subsampled and completed an interviewer-administered questionnaire and provided a urine sample for biological screening. Urinalyses showed that 8.8% (95% CI: 6.7–10.9) of the subsample tested positive for at least one illicit drug. This is higher than the self-reported prevalence (3.6%). In addition, 19.6% (95% CI: 16.3–22.8) of the sub-sample tested positive for alcohol which is lower than the self-reported prevalence (36.9%). There are high levels of substance use among pregnant women attending public sector antenatal clinics. There is a need for routine screening for AOD use and appropriate responses depending on the women's level of risk. PMID:24639899

    Background and aims Minimum unit pricing is a fiscal intervention intended to tackle the social and health harms from alcohol to individual drinkers and wider society. This paper presents the first large-scale qualitative examination of how newsprint media framed the debate around the harms of alcohol consumption to ‘others’ during the development and passing of minimum unit pricing legislation in Scotland. Methods Qualitative content analysis was conducted on seven UK and three Scottish national newspapers between 1 January 2005 and 30 June 2012. Relevant articles were identified using the electronic databases Nexis UK and Newsbank. A total of 403 articles focused on the harms of alcohol consumption to ‘others’ and were eligible for detailed coding and analysis. Results Alcohol harms to wider society and communities were identified as being a worsening issue increasingly affecting everyone through shared economic costs, social disorder, crime and violence. The availability of cheap alcohol was blamed, alongside a minority of ‘problem’ youth binge drinkers. The harm caused to families was less widely reported. Conclusions If news reporting encourages the public to perceive the harms caused by alcohol to wider society as having reached crisis point, a population-based intervention may be deemed necessary and acceptable. However, the current focus in news reports on youth binge drinkers may be masking the wider issue of overconsumption across the broader population. PMID:24279299

    The mountain pine beetle, Dendroctonus ponderosae, is a native species of bark beetle (Coleoptera: Curculionidae) that caused unprecedented damage to the pine forests of British Columbia and other parts of western North America and is currently expanding its range into the boreal forests of central and eastern Canada and the USA. We conducted a large-scale gene expression analysis (RNA-seq) of mountain pine beetle male and female adults either starved or fed in male-female pairs for 24 hours on lodgepole pine host tree tissues. Our aim was to uncover transcripts involved in coniferophagous mountain pine beetle detoxification systems during early host colonization. Transcripts of members from several gene families significantly increased in insects fed on host tissue including: cytochromes P450, glucosyl transferases and glutathione S-transferases, esterases, and one ABC transporter. Other significantly increasing transcripts with potential roles in detoxification of host defenses included alcohol dehydrogenases and a group of unexpected transcripts whose products may play an, as yet, undiscovered role in host colonization by mountain pine beetle.

    2015-01-01

    Detoxification is a vital cellular task that, if lacking, can lead to early morbidity and mortality. The process of detoxification involves the mobilization, biotransformation, and elimination of toxicants of exogenous and endogenous origin. This article discusses the phase I and phase II detoxification and biotransformation pathways and promotes using food to support these highly complex processes. The author identifies the comprehensive elimination diet as a useful therapeutic tool for clinicians and patients to use to achieve detoxification. Using this diet, the patient removes the most common allergenic foods and beverages from the diet and replaces them with nonallergenic choices for a period of 4 wk, gradually adding back the eliminated foods and observing their effects. Another effective clinical tool that the author discusses is the detox-focused core food plan, which identifies the variety of foods required to supply key nutrients that can maximize the effectiveness of detoxification. Finally, the author provides a case study in which these tools were used to help a patient suffering from major, debilitating illnesses that resulted from exposure to malathion, including severe vomiting and diarrhea, headaches, night sweats, severe arthralgias and myalgias, episcleritis, and shortness of breath. The article details the interventions used and the clinical results (ie, successful resolution of most issues after 3 mo). PMID:26026145

    Aims: The aim of the study was to assess the likely impact of the Scottish Government's proposed alcohol minimum unit pricing (MUP) policy on community off-sales outlets (convenience stores or corner shops), and, in turn, on the local people who purchase drinks at such premises. This research adds to our knowledge by linking sales of alcohol products which will be affected by MUP (e.g. at the proposed 50 ppu) to the types of communities where these are the ‘drinks-of-choice’. Methods: A survey of independent community off-sales operating within the city of Glasgow, Scotland (n = 271) returned 144 completed questionnaires enquiring about each shop's customer base, best-selling alcohol products and participating shopkeepers' views on MUP. Responses were measured against current alcohol product prices (i.e. whether potentially affected by MUP) and local levels of socio-economic deprivation. Results: Participating shopkeepers were divided in their support for MUP, although more were in favour than against. Support for MUP tended to be rooted in business concerns. A majority reported having at least one best-selling alcohol product which will be affected by the proposed MUP policy at current prices, with the beverages that would be most affected (e.g. white cider) tending to be best-sellers at shops serving deprived communities. Conclusion: MUP is likely to impact most in socio-economically deprived communities. This is also where alcohol-related health and other inequalities are currently greatest. PMID:24293505

    BACKGROUND This paper examines the effect of early adolescent alcohol use on mid-adolescent school suspension, truancy, commitment, and academic failure in Washington State, United States (US) and Victoria, Australia. Also of interest was whether associations remain after statistically controlling for other factors known to predict school outcomes. METHODS State-representative student samples were surveyed in 2002 (grade 7; N = 1858) and followed up annually to 2004 (grade 9) in both venues. Students completed a modified version of the Communities That Care survey to report alcohol use, school outcomes and risk and protective factors. Response rates were above 74% and retention rates exceeded 98% in both places. RESULTS Controlling for grade 7 risk factors, grade 7 current alcohol use and heavy episodic drinking were associated with grade 8 school suspension. Grade 7 current and frequent alcohol use and heavy episodic drinking were linked to grade 9 truancy. In fully adjusted analyses, associations between early alcohol use and academic failure and low school commitment did not remain. CONCLUSIONS Although alcohol use is one factor influencing school performance and connection, there are other risk factors that need to be targeted to improve school outcomes. PMID:25274170

    The aim of the present study is to evaluate lofexidine and clonidine, in an accelerated opiate detoxification procedure (3 days), without anaesthesia. Forty heroin-dependent individuals were detoxified, evaluating withdrawal symptoms, craving levels, mood changes, urine toxicologic screens, and dropout during therapy with either (1) clonidine, oxazepam, baclofen, and ketoprofene, with naloxone and naltrexone for 3 days (20 subjects) or (2) lofexidine, oxazepam, baclofen, and ketoprofene with naloxone and naltrexone for 3 days (20 subjects). Both clonidine and lofexidine rapid detoxifications were found effective. The subjects treated with lofexidine showed significantly lower levels of withdrawal symptoms, fewer mood problems, less sedation and hypotension. No significant differences in craving levels, morphine metabolites in urine, or dropout rate were evidenced between the two groups. The early use of naltrexone during detoxification in combination with either alpha-2-agonist facilitated the acceptance for long-term naltrexone treatment. Lofexidine appeared to be more useful than clonidine in a 3-day accelerated opiate detoxification, not only to counteract withdrawal symptoms, but also in the treatment of dysphoria and mood changes. Because lofexidine does not produce hypotension, safe outpatient treatment, without hospital support, could be possible. PMID:11516922

    2014-01-01

    Treatment of alcohol dependence consist of alcohol detoxification with withdrawal alleviation and relapse prevention or maintenance therapy. Drugs of choice for alcohol withdrawal cure are benzodiazepines and anticonvulsants are an alternative for them. Relapse prevention and alcohol abuse alleviation are carried out using disulfiram, acamprosate, naltrexone and nalmefene. Moreover, therapeutic possibilities of memantine, gabapentine, pregabalin, baclofen, modafinil, ondansetron D-cycloserine and aripiprazole are studying nowadays. Use of selective serotonin reuptake inhibitors including fluvoxamine for alcohol patients is of great importance due to frequent comorbidity of alcoholism, depression and anxiety. There are some doubtful methods of alcoholism treatment accepted in Russian addictive medicine such as clearance detoxification and use of antipsychotics for craving elimination. PMID:24988976

    The influences of parental divorce and alcohol abuse on adult offspring lifetime suicide attempt have not been examined in national data. This study analyzed data from the 2001-2002 NESARC to estimate main and interaction effects of parental divorce and alcohol abuse on lifetime suicide attempt. Adjusted for controls, parental divorce and parental alcohol abuse independently increased odds of lifetime suicide attempt. The effect of parental divorce was not significantly moderated by parental alcohol abuse. Further research is needed to examine whether additional parental and offspring psychiatric and substance use covariates attenuate the association between parental divorce and lifetime suicide attempt.

    Although it is well known that B-vitamin deficiencies directly affecting the brain are common in alcohol misuse, no concise guidelines on the use of vitamin supplements in alcohol misusers currently exist in the UK. The purpose of this study was to assess current practice and opinion among UK physicians. Questionnaires were completed by a total of 427 physicians comprising Accident and Emergency (A&E) specialists and psychiatrists, with a response rate of 25%. The main findings were that vitamin deficiency was perceived as being uncommon amongst alcohol misusers (<25%) and there was no consensus as to which B vitamins are beneficial in treatment or the best method of administration of B-vitamin supplementation. The majority of psychiatrists favoured oral administration for prophylaxis against the Wernicke-Korsakoff syndrome in chronic alcohol misusers and parenteral therapy in patients with signs of Wernicke-Korsakoff syndrome. Whilst only just over half the A&E specialists expressed a preference, most favoured parenteral therapy in both cases. Most respondents did not currently have a unit policy/protocol on the management of vitamin supplementation in chronic alcohol misusers. Overall, the findings suggest that there is wide variation in current practice and highlight the need for guidelines in this area. PMID:10659721

    Many patients fail to initiate aftercare for addictive disease rehabilitation following detoxification. This study of 136 inpatients compared characteristics of those who initiated aftercare (behavior therapy or self-help programs) during the week following discharge with those who did not. Among this group of patients, 77% (91/119) linked to aftercare. Self-help treatment related components were associated with increased aftercare treatment attendance rates and included: having a copy of the “12 Steps” (81% vs. 46%, P = .002), having read self-help literature (73% vs. 42%, P = .007) and having telephone numbers of self-help program members (50% vs. 18%, P = .008). Those who initiated aftercare treatment were also more likely to have remained abstinent from drugs and alcohol (81% vs. 39%, P <.001). Having self-help treatment-related components were associated with increased rates of aftercare attendance following hospital inpatient detoxification. PMID:19197592

    A strategy for the conjugation of alcohol-containing payloads to antibodies has been developed and involves the methylene alkoxy carbamate (MAC) self-immolative unit. A series of MAC β-glucuronide model constructs were prepared to evaluate stability and enzymatic release, and the results demonstrated high stability at physiological pH in a substitution-dependent manner. All the MAC model compounds efficiently released alcohol drug surrogates under the action of β-glucuronidase. To assess the MAC technology for ADCs, the potent microtubule-disrupting agent auristatin E (AE) was incorporated through the norephedrine alcohol. Conjugation of the MAC β-glucuronide AE drug linker to the anti-CD30 antibody cAC10, and an IgG control antibody, gave potent and immunologically specific activities in vitro and in vivo. These studies validate the MAC self-immolative unit for alcohol-containing payloads within ADCs, a class that has not been widely exploited. PMID:27198854

    2015-01-01

    Alcohol use disorders (AUD) during pregnancy are less prevalent than in non-pregnant women, but they can create a host of clinical challenges when encountered. Unfortunately, there is little research information available to guide clinical decision-making in this population. Drinking alcohol during pregnancy can have negative consequences on both fetus and mother, but there is controversy regarding the volume of alcohol consumption that correlates with these consequences. There is little evidence to support the use of pharmacologic interventions for AUD during pregnancy. Similarly, there are few data to guide management of alcohol detoxification in pregnant women, and the use of benzodiazepines (the mainstay of most alcohol detoxification protocols) in pregnant women is controversial. Despite a lack of robust data to guide management of AUDs in pregnancy, clinicians must nonetheless make management decisions when confronted with these challenging situations. Therefore, this paper reviews the epidemiology of AUDs in pregnancy, and the pharmacologic management of both AUDs and alcohol withdrawal in pregnant women, to better inform clinicians about what is known about managing these co-occurring conditions.

    Alcohol use disorders (AUDs) are less prevalent in pregnant women than in nonpregnant women, but these disorders can create a host of clinical challenges when encountered. Unfortunately, little evidence is available to guide clinical decision making in this population. Drinking alcohol during pregnancy can have negative consequences on both fetus and mother, but it remains controversial as to the volume of alcohol consumption that correlates with these consequences. Likewise, little evidence is available to support the use of particular pharmacologic interventions for AUDs during pregnancy or to guide the management of alcohol detoxification in pregnant women. The use of benzodiazepines (the mainstay of most alcohol detoxification protocols) in pregnant women is controversial. Nevertheless, despite the lack of robust data to guide management of AUDs in pregnancy, clinicians need to make management decisions when confronted with these challenging situations. In that context, this article reviews the epidemiology of AUDs in pregnancy and the pharmacologic management of both AUDs and alcohol withdrawal in pregnant women, with the goal of informing clinicians about what is known about managing these co-occurring conditions.

    Objective To examine the validity of police-reported alcohol data for drivers involved in fatal motor carrier crashes. Material and Methods We determined the availability of blood alcohol concentration (BAC) and police-reported alcohol data on 157,702 drivers involved in fatal motor carrier crashes between 1982 – 2005 using Fatality Analysis and Reporting System (FARS) data. Drivers were categorized as motor carrier drivers if they operated a vehicle with a gross vehicle weight rating of greater than 26,000 pounds. Otherwise, they were classified as non motor carrier drivers. The sensitivity and specificity of police-reported alcohol involvement were estimated for both driver types. Results Of the 157,702 drivers, 18% had no alcohol information, 15% had BAC results, 42% had police-reported alcohol data, and 25% had both. Alcohol information varied significantly by driver, crash, and vehicle characteristics. For example, motor carrier drivers were significantly more likely (51%) to have BAC testing results compared to non motor carrier drivers (31%) (p < 0.001). The sensitivity of police-reported alcohol involvement for a BAC level ≥ 0.08 was 83% (95% CI 79%, 86%) for motor carrier drivers and 90% (95% CI 89%, 90%) for non motor carrier drivers. The specificity rates were 96% (95% CI 95%, 96%) and 91% (95% CI 90%, 91%), respectively. Conclusions The sensitivity and specificity of police-reported alcohol involvement are reasonably high for drivers involved in fatal motor carrier crashes. Further research is needed to determine the extent to which the accuracy of police-reported alcohol involvement may be overestimated because of verification bias. PMID:19527818

    Chronic alcohol consumption results in considerable damage to many of the body's organs, and particularly to the brain. Beyond the confusional state occurring with acute intoxication or withdrawal, alcohol abuse is responsible of a constellation of neuropsychiatric syndromes including cognitive dysfunction, Wernicke-Korsakoff Syndrome, alcoholic cerebellar degeneration, Marchiafava-Bignami disease and alcohol-related dementia, ARD. ARD would account for nearly 20% of all admissions to state mental hospitals in the United-States. According to the DSM-IV, ARD is defined by a dementia associated with alcohol abuse. However, the concept of a dementia directly related to the neurotoxicity of alcohol for brain neurons is still a matter of debate. Several hypotheses have been proposed to explain the mechanisms of cognitive deficits related to chronic alcohol intoxication. This paper presents the epidemiological, neuropathological, neurochemical and clinical data on ARD. Alcoholism is responsible for cognitive deficits of various severity, which could be reversible or not with alcohol abstinence, but can also participate to the cognitive impairment related to other pathologies, such as Alzheimer disease. On account of this review, it is suggested that the term alcohol-related cognitive impairment should be more convenient than that of ARD, more restrictive and more confusing. Presently, there are no established treatment for alcohol-related cognitive impairment. Alcohol abstinence is a most important step. Psychosocial interventions are essential to support the patients in the daily life. PMID:15683959

    The alcohol withdrawal syndrome (AWS) is a common management problem in hospital practice for neurologists, psychiatrists and general physicians alike. Although some patients have mild symptoms and may even be managed in the outpatient setting, others have more severe symptoms or a history of adverse outcomes that requires close inpatient supervision and benzodiazepine therapy. Many patients with AWS have multiple management issues (withdrawal symptoms, delirium tremens, the Wernicke-Korsakoff syndrome, seizures, depression, polysubstance abuse, electrolyte disturbances and liver disease), which requires a coordinated, multidisciplinary approach. Although AWS may be complex, careful evaluation and available treatments should ensure safe detoxification for most patients. PMID:17986499

    On May 24th 2012, Scotland passed the Alcohol (Minimum Pricing) Bill. Minimum unit pricing (MUP) is an intervention that raises the price of the cheapest alcohol to reduce alcohol consumption and related harms. There is a growing literature on industry's influence in policymaking and media representations of policies, but relatively little about frames used by key claim-makers in the public MUP policy debate. This study elucidates the dynamic interplay between key claim-makers to identify lessons for policy advocacy in the media in the UK and internationally. Content analysis was conducted on 262 articles from seven UK and three Scottish national newspapers between 1st May 2011 and 31st May 2012, retrieved from electronic databases. Advocates' and critics' constructions of the alcohol problem and MUP were examined. Advocates depicted the problem as primarily driven by cheap alcohol and marketing, while critics' constructions focused on youth binge drinkers and dependent drinkers. Advocates justified support by citing the intervention's targeted design, but critics denounced the policy as illegal, likely to encourage illicit trade, unsupported by evidence and likely to be ineffective, while harming the responsible majority, low-income consumers and businesses. Critics' arguments were consistent over time, and single statements often encompassed multiple rationales. This study presents advocates with several important lessons for promoting policies in the media. Firstly, it may be useful to shift focus away from young binge drinkers and heavy drinkers, towards population-level over-consumption. Secondly, advocates might focus on presenting the policy as part of a wider package of alcohol policies. Thirdly, emphasis on the success of recent public health policies could help portray the UK and Scotland as world leaders in tackling culturally embedded health and social problems through policy; highlighting past successes when presenting future policies may be a valuable

    Context Scotland is the first country in the world to pass legislation introducing a minimum unit price (MUP) for alcohol in an attempt to reduce consumption and associated harms by increasing the price of the cheapest alcohol. We investigated the competing ways in which policy stakeholders presented the debate. We then established whether a change in framing helped explain the policy's emergence. Methods We conducted a detailed policy case study through analysis of evidence submitted to the Scottish parliament, and in-depth, one-to-one interviews (n = 36) with politicians, civil servants, advocates, researchers, and industry representatives. Findings Public- and voluntary-sector stakeholders tended to support MUP, while industry representatives were more divided. Two markedly different ways of presenting alcohol as a policy problem were evident. Critics of MUP (all of whom were related to industry) emphasized social disorder issues, particularly among young people, and hence argued for targeted approaches. In contrast, advocates for MUP (with the exception of those in industry) focused on alcohol as a health issue arising from overconsumption at a population level, thus suggesting that population-based interventions were necessary. Industry stakeholders favoring MUP adopted a hybrid framing, maintaining several aspects of the critical framing. Our interview data showed that public health advocates worked hard to redefine the policy issue by deliberately presenting a consistent alternative framing. Conclusions Framing alcohol policy as a broad, multisectoral, public health issue that requires a whole-population approach has been crucial to enabling policymakers to seriously consider MUP, and public health advocates intentionally presented alcohol policy in this way. This reframing helped prioritize public health considerations in the policy debate and represents a deliberate strategy for consideration by those advocating for policy change around the world and in

    Eighteen heroin addicts were treated as outpatients with acupuncture, electrical stimulation and staplepuncture. Results of treatment were compared with results in two similar groups of 18 persons in whom detoxification was carried out using methadone and propoxyphene napsylate. Withdrawal symptoms were relieved for about two hours in most of the patients after a treatment episode of acupuncture and electrical stimulation. Staplepuncture, which is the manipulation by hand of a surgical staple implanted in the concha of the ear, was reported to relieve withdrawal symptoms at least partially in approximately 40 percent of subjects. In only one person of the group treated with acupuncture or staplepuncture was complete detoxification achieved, compared with 13 and 10 persons, respectively, in the methadone and propoxyphene napsylate groups (p<.001). Use of acupuncture and staplepuncture in outpatient clinics may be limited unless techniques can be found that will relieve withdrawal symptoms for a longer period than that observed in this study.

    Few studies have examined the behavioral and protective correlates of alcohol use among young Hispanics. Using a national sample (N = 7,606), logistic regression and latent profile analysis (LPA) are employed to examine the relationships between alcohol use, psychosocial factors, and externalizing behavior among Hispanics during early adolescence. Early drinkers are more likely to report truancy, fighting, smoking, and drug use. LPA results revealed a three class solution. Classes identified included: psychosocial risk (41.11%), moderate protection (39.44%), and highly religious (19.44%). Alcohol use is clearly associated with externalizing behavior; however, an important degree of psychosocial and behavioral heterogeneity nevertheless exists. PMID:24491151

    Microalgae are aquatic organisms possessing molecular mechanisms that allow them to discriminate non-essential heavy metals from those essential ones for their growth. The different detoxification processes executed by algae are reviewed with special emphasis on those involving the peptides metallothioneins, mainly the post transcriptionally synthesized class III metallothioneins or phytochelatins. Also, the features that make microalgae suitable organisms technologies specially to treat water that is heavily polluted with metals is discussed. PMID:16405948

    The toxic fermentation inhibitors in lignocellulosic hydrolysates raise serious problems for the microbial production of fuels and chemicals. Furfural is considered to be one of the most toxic compounds among these inhibitors. Here, we describe the detoxification of furfural in Corynebacterium glutamicum ATCC13032 under both aerobic and anaerobic conditions. Under aerobic culture conditions, furfuryl alcohol and 2-furoic acid were produced as detoxification products of furfural. The ratio of the products varied depending on the initial furfural concentration. Neither furfuryl alcohol nor 2-furoic acid showed any toxic effect on cell growth, and both compounds were determined to be the end products of furfural degradation. Interestingly, unlike under aerobic conditions, most of the furfural was converted to furfuryl alcohol under anaerobic conditions, without affecting the glucose consumption rate. Both the NADH/NAD(+) and NADPH/NADP(+) ratio decreased in the accordance with furfural concentration under both aerobic and anaerobic conditions. These results indicate the presence of a single or multiple endogenous enzymes with broad and high affinity for furfural and co-factors in C. glutamicum ATCC13032. PMID:25112225

    Time perspective is an individual difference variable which assesses the extent to which orientation to the past, present and future affects current behaviors. The present study investigated the viability of temporal profiles and the degree (if any) to which these predict meaningful differences in alcohol-related problems. Participants were undergraduates recruited from a University in the North West of England. Full survey data were available for 455 individuals (aged 18-25; 49.7% male) on (a) time perspective, and (b) alcohol-related problems. Four profiles emerged and were labeled Future-Positive, Present, Past Negative-Future, and Ambivalent. As hypothesized, the Future-Positive profile was associated with the best alcohol-related outcomes. The Present profile was associated with the worst outcomes. This study demonstrates that temporal profiles are associated with alcohol-related problems. PMID:26735914

    This paper examines whether increased consumption of tobacco and alcohol products by minority groups is a function of the target marketing campaigns directed at these groups by marketers, and whether such contributes to the perpetuation of racism. First, a description of the tobacco and alcohol consumption rates of blacks and Hispanics compared to whites is presented, including a comparative analysis of the health effects and mortality rates resulting from the consumption of tobacco and alcohol. Second, the paper examines specific marketing strategies of targeting tobacco and alcohol products to ethnic minority consumers. This is followed by a discussion of whether these practices are a deliberate strategy driven by racism or just the pursuit of profit. A framework for answering the question is provided. Finally, the paper assesses the prospects for change in the future, and analyzes specific needs for future research. PMID:8882838

    The effect of early adolescent alcohol use on antisocial behavior was examined at one- and two-year follow-up in Washington, United States and Victoria, Australia. Each state used the same methods to survey statewide representative samples of students (N = 1,858, 52% female) in 2002 (Grade 7 [G7]), 2003 (Grade 8 [G8]), and 2004 (Grade 9 [G9]). Rates of lifetime, current, frequent, and heavy episodic alcohol use were higher in Victoria than Washington State, whereas rates of five antisocial behaviors were generally comparable across states. After controlling for established risk factors, few associations between alcohol use and antisocial behavior remained, except that G7 current use predicted G8 police arrests and stealing and G9 carrying a weapon and stealing; G7 heavy episodic use predicted G8 and G9 police arrests; and G7 lifetime use predicted G9 carrying a weapon. Hence, risk factors other than alcohol were stronger predictors of antisocial behaviors. PMID:25132702

    The relapse rate after discharge from inpatient detoxification is high. The objective of this pilot study is to assess the sociodemographic, clinical and therapeutic factors associated with maintaining abstinence in patients who participated in a brief motivational interviewing group during admission for detoxification. A total of 46 patients, diagnosed substance dependent according to DSM -IV, and admitted to the Hospital Detoxification Unit, participated in a brief motivational interviewing group. Sociodemographic, clinical, motivation to change (University of Rhode Island Change Assessment, URICA) and satisfaction with the treatment group (Treatment Perceptions Questionnaire, CPT) data were collected. Abstinence and treatment retention two months after discharge were assessed by weekly telephone calls. A survival analysis was performed. Being male, having more cognitions of the maintenance stage of change at discharge, being satisfied with group therapy and therapist during hospitalization are associated with longer abstinence after discharge. The brief motivational interviewing group approach with patients admitted for detoxification is related to greater likelihood of maintaining abstinence and subsequent treatment retention.

    Background The lack of adequate and standardized recording of leading risk factors for morbidity and mortality in medical records have downstream effects on research based on administrative databases. The measurement of healthcare is increasingly based on risk-adjusted outcomes derived from coded comorbidities in these databases. However inaccurate or haphazard assessment of risk factors for morbidity and mortality in medical record codes can have tremendous implications for quality improvement and healthcare reform. Objective We aimed to compare the prevalence of obesity, overweight, tobacco use and alcohol abuse of a large administrative database with a direct data collection survey. Materials and Methods We used the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes for four leading risk factors in the United States Nationwide Inpatient Sample (NIS) to compare them with a direct survey in the Behavioral Risk Factor Surveillance System (BRFSS) in 2011. After confirming normality of the risk factors, we calculated the national and state estimates and Pearson’s correlation coefficient for obesity, overweight, tobacco use and alcohol abuse between NIS and BRFSS. Results Compared with direct participant questioning in BRFSS, NIS reported substantially lower prevalence of obesity (p<0.01), overweight (p<0.01), and alcohol abuse (p<0.01), but not tobacco use (p = 0.18). The correlation between NIS and BRFSS was 0.27 for obesity (p = 0.06), 0.09 for overweight (p = 0.55), 0.62 for tobacco use (p<0.01) and 0.40 for alcohol abuse (p<0.01). Conclusions The prevalence of obesity, overweight, tobacco smoking and alcohol abuse based on codes is not consistent with prevalence based on direct questioning. The accuracy of these important measures of health and morbidity in databases is critical for healthcare reform policies. PMID:26536469

    In an open label pilot study, five opiate-dependent patients underwent baclofen-assisted opiate detoxification after abrupt discontinuation of methadone. Patients received baclofen in oral doses up to 80 mg/day, and all patients subjectively reported some reduction in discomfort. However, 3 of 5 (60%) patients could not complete detoxification with baclofen, primarily because of insufficient suppression of vomiting, myalgias, and headache. These patients successfully completed their detoxification with clonidine. These findings suggest that, in the dose range studied, baclofen is of limited use as a primary treatment for opiate dependence, although adjunctive roles for this medication in detoxification should be explored.

    We examined co-occurrence of (comorbid) alcohol, drug, and non-substance use psychiatric disorders in a population sample of Mexican-origin adults from rural and urban areas of central California. Co-occurring lifetime rates of alcohol or other drug disorders with non-substance use psychiatric disorders, or both, were 8.3% for men and 5.5% for women and were 12.3% for the US born and 3.5% for immigrants. Alcohol abuse or dependence with co-occurring psychiatric disorders is a primary disorder among Mexican-origin adult males (7.5% lifetime prevalence). US-born men and women are almost equally likely to have co-occurring disorders involving substances. Cobormidity is expected to increase in the Mexican-origin population owing to acculturation effects of both sexes. PMID:12835179

    Microorganisms have evolved various mechanisms to detoxify arsenic, an ubiquitous environmental toxin. Known mechanisms include arsenite efflux, arsenate reduction followed by arsenite efflux and arsenite methylation. In this issue, Chen et al. describe a novel mechanism for arsenate detoxification via synergistic interaction of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and a major facilitator superfamily protein (ArsJ). They propose that GAPDH catalyzes the formation of 1-arseno-3-phosphoglycerate, which is then extruded out of the cell by ArsJ. The significance of this pathway and questions for further research are discussed. PMID:27072877

    2015-12-01

    Mycotoxins have been identified as important toxins affecting animal species and humans ever since the discovery of aflatoxin B1 in 1960. Mycotoxigenic fungi are ubiquitous in nature and are held responsible for economic loss as they decrease crop yield and quality of food. The presence of fungi and their mycotoxins are reported not only in food grains but also in medicinal herbs and processed foods. Since prevention is not always possible, detoxification of mycotoxins have been attempted using several means; however, only few have been accepted for practical use, e.g. ammonia in the corn industry. Organizations such as the World Health Organization, US Food and Drug Administration and European Union have set regulations and safety limits of important mycotoxins, viz. aflatoxins, fusarium toxins, ochratoxin, patulin zearalenone, etc., to ensure the safety of the consumers. This review article is a brief and up-to-date account of the occurrence, detection and detoxification of mycotoxins for those interested in and considering research in this area. PMID:26648039

    In this study, we investigated the simultaneous saccharification, fermentation and detoxification SSDF process of steam-exploded cedar using a detoxification microorganism, Ureibacillus thermosphaericus A1, to facilitate efficient ethanol production. Steam explosion was applied as a pretreatment before enzymatic saccharification followed by alcohol fermentation. The highest glucose conversion rate was observed in the sample pretreated with a steam pressure of 45atm for 5min. Alcohol production by a heat-tolerant yeast, Saccharomyces cerevisiae BA11, was inhibited strongly by inhibitory materials present in the steam-exploded cedar, such as formic acid, furfural, and 5-hydroxymethylfurfural. The maximum amount of ethanol, i.e., 0.155g ethanol/g dry steam-exploded cedar, which corresponded to 74% of the theoretical ethanol yield, was obtained using the SSDF when U. thermosphaericus A1 degraded the inhibitory materials. A fed batch SSDF culture, in which U. thermosphaericus A1 was used to maintain low concentrations of inhibitory materials, was effective for increasing the ethanol concentration. PMID:25461004

    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. PMID:25307602

    A psychoanalytic-developmental treatment model includes individual and group psychotherapy which enables compulsive freebase cocaine smokers to articulate explanations for their drug dependence. Relapse prevention education includes recommendations for aftercare treatment. Psychosocial history and DSM-III diagnostic data (N = 31) reveals histories of dysfunctional family dynamics, high rates of depressive disorders, and personality disorders. A case history illustrates application of our treatment model and problems in currently available post-detox treatment. Residential therapeutic communities (TCs) need to offer variable program lengths and specialized crack residences in therapeutic milieus with trained clinical staff. TC programs should offer inpatient psychotherapy, family therapy, and provide direct entrance into program affiliated outpatient services. Recommendations for outpatient services include adjuncts to established anonymous self-help group networks in order to reduce changes of relapse. PMID:3041012

  13. A 'symptom-triggered' approach to alcohol withdrawal management.

    PubMed

    Murdoch, Jay; Marsden, Janet

    In acute hospital settings, alcohol withdrawal often causes significant management problems and complicates a wide variety of concurrent conditions, placing a huge burden on the NHS. A significant number of critical incidents around patients who were undergoing detoxification in a general hospital setting led to the need for a project to implement and evaluate an evidence-based approach to the management of alcohol detoxification-a project that included a pre-intervention case note audit, the implementation of an evidence-based symptom-triggered detoxification protocol, and a post-intervention case note audit. This change in practice resulted in an average reduction of almost 60% in length of hospital stay and a 66% reduction in the amount of chlordiazepoxide used in detoxification, as well as highlighting that 10% of the sample group did not display any signs of withdrawal and did not require any medication. Even with these reductions, no patient post-intervention developed any severe signs of withdrawal phenomena, such as seizures or delirium tremens. The savings to the trust (The Pennine Acute Hospital Trust) are obvious,but the development of a consistent, quality service will lead to fewer long-term negative effects for patients that can be caused by detoxification. This work is a project evaluation of a locally implemented strategy, which, it was hypothesised,would improve care by providing an individualised treatment plan for the management of alcohol withdrawal symptoms.

    The lignin content of biomass can impact the ease and cost of biomass processing. Lignin reduction through breeding and genetic modification therefore has potential to reduce costs in biomass-processing industries (e.g. pulp and paper, forage, and lignocellulosic ethanol). We investigated compositional changes in two low-lignin alfalfa (Medicago sativa) lines with antisense down-regulation of p-coumarate 3-hydroxylase (C3H) or hydroxycinnamoyl-CoA:shikimate hydroxycinnamoyltransferase (HCT). We investigated whether the difference in reactivity during lignification of 4-coumaryl alcohol (H) monomers versus the naturally dominant sinapyl alcohol and coniferyl alcohol lignin monomers alters the lignin structure. Sequential base extraction readily reduced the H monomer content of the transgenic lines, leaving a residual lignin greatly enriched in H subunits; the extraction profile highlighted the difference between the control and transgenic lines. Gel permeation chromatography of isolated ball-milled lignin indicated significant changes in the weight average molecular weight distribution of the control versus transgenic lines (CTR1a, 6000; C3H4a, 5500; C3H9a, 4000; and HCT30a, 4000).

    Drugged driving is a safety issue of increasing public concern. Using data from the Fatality Analysis Reporting System for 1999–2010, we assessed trends in alcohol and other drugs detected in drivers who were killed within 1 hour of a motor vehicle crash in 6 US states (California, Hawaii, Illinois, New Hampshire, Rhode Island, and West Virginia) that routinely performed toxicological testing on drivers involved in such crashes. Of the 23,591 drivers studied, 39.7% tested positive for alcohol and 24.8% for other drugs. During the study period, the prevalence of positive results for nonalcohol drugs rose from 16.6% in 1999 to 28.3% in 2010 (Z = −10.19, P < 0.0001), whereas the prevalence of positive results for alcohol remained stable. The most commonly detected nonalcohol drug was cannabinol, the prevalence of which increased from 4.2% in 1999 to 12.2% in 2010 (Z = −13.63, P < 0.0001). The increase in the prevalence of nonalcohol drugs was observed in all age groups and both sexes. These results indicate that nonalcohol drugs, particularly marijuana, are increasingly detected in fatally injured drivers. PMID:24477748

  18. Detoxification of aromatic pollutants by fungal enzymes

    SciTech Connect

    Bollag, J.M.; Dec, J.

    1995-12-31

    Fungal enzymes, such as laccase, peroxidase, and tyrosinase, play a prominent role in catalyzing the transformation of various aromatic compounds in the environment. The enzyme-mediated oxidative coupling reaction results in covalent binding of chlorinated phenols and anilines to soil organic matter or polymerization of the substrates in aquatic systems. Both of these processes are accompanied by a detoxification effect. Therefore, it has been postulated that they be exploited for the treatment of polluted soil and water. The mechanism and efficiency of oxidative coupling in pollutant removal were studied by incubation of chlorinated phenols and anilines with various humic substances or soil and analysis of the reaction products by chromatography and mass and {sup 13}C nuclear magnetic resonance (NMR) spectrometry. The decontamination effect could be enhanced by optimization of the reaction conditions and immobilization of enzymes on solid materials. The results obtained strongly support the concept of using enzymes for control of environmental pollution.

    In contrast to many remedial techniques that simply transfer hazardous wastes from one part of the environment to another (e.g., off-site landfilling), in situ restoration may offer a safe and cost-effective solution through transformation (to less hazardous products) or destruction of recalcitrant organics. Currently, the US Environmental Protection Agency and US Department of Energy are encouraging research that addresses the development of innovative alternatives for hazardous-waste control. One such alternative is biotic and abiotic immobilization and detoxification of polynuclear aromatic hydrocarbons (PNAs) as associated with the soil humification process. This paper discusses (1) the possibility of using abiotic catalysis (with manganese dioxide) to polymerize organic substances; (2) aspects associated with the thermodynamics and kinetics of the process, and (3) a simple model upon which analyses may be based. 36 refs., 7 figs., 3 tabs.

    This paper estimates 1993 U.S. highway crash incidence and costs by driver age, alcohol use, victim age, occupant status, and restraint use. Notable findings are: (1) crash costs of novice drivers are high enough to yield preliminary benefit-cost ratios around 4-8 for a provisional licensing system that restricts driving after midnight and 11 for zero alcohol tolerance for young drivers with violators receiving a 6-month suspension; (2) the costs to people other than the intoxicated driver per mile driven at BACs of 0.08-0.099% exceed the value of driver mobility; (3) the safety costs of drunk driving appear to exceed $5.80 per mile, compared with $2.50 per mile driven at BACs of 0.08-0.099%, and $0.11 per mile driven sober; (4) highway crashes cause an estimated 3.2% of U.S. medical spending, including more than 14% of medical spending for ages 15-24; (5) ignoring crash-involved occupants whose restraint use is unknown, the 13% of occupants who police reported were traveling unrestrained accounted for an estimated 42% of the crash costs; and (6) if these unrestrained occupants buckled up, the medical costs of crashes would decline by an estimated 18% (almost $4 billion annually) and the comprehensive costs by 24%.

    Background This study aimed to determine between-country differences and changes over time in the portrayal of youth risk behaviors in films rated for youth in Argentina, Brazil, Mexico and the United States. Methods Content and ratings were analyzed for 362 films that were popular across all four countries from 2002–2009. Country-specific ratings were classified as either youth or adult, and Generalized Estimating Equations were used to determine between-country differences in the presence of tobacco, alcohol, drugs, sexual content, and violence in youth-rated films. Within-country differences in this content over time were also assessed, comparing films released from 2002–2005 with those released from 2006–2009. Results In the US, films rated for youth were less likely to contain all five risk behaviors than in youth-rated films in Argentina, Brazil, and, when the “15 and older” rating was considered a youth rating, in Mexico. All three Latin American countries “downrated” films that received an adult rating in the US. Nevertheless, tobacco and drug use in youth-rated films declined over time in all countries, whereas moderate to extreme alcohol use and violence involving children or youth increased in all countries. Conclusions Tobacco and drug use have declined in popular US films, but these behaviors are still prevalent in films rated for youth across the Americas. The apparent success of advocacy efforts to reduce tobacco and other drugs in films suggests that similar efforts be directed to reduce alcohol portrayals. PMID:24316001

    An overusing and an addiction to alcoholic drinks are important problems in a medical society. The studies made in the United States had documented that about 8-12% doctors were addicted to alcohol. In many cases the doctors are able to keep their problem as a secret and their activity is satisfied up to the moment when a decrease is noticed. Some factors--such as a high level of stress--predispose doctors to alcoholic problems especially surgeons. Alcohol problems should be identified as early as possible, and therapy ought to be given as well. There is no reason to hide the problem. PMID:19025048

    Aims: To explore how policy actors attempted to deliberately frame public debate around alcohol minimum unit pricing (MUP) in the UK by comparing and contrasting their constructions of the policy in public (newspapers), semi-public (evidence submissions) and private (interviews). Methods: Content analysis was conducted on articles published in ten national newspapers between 1 January 2005 and 30 June 2012. Newsprint data were contrasted with alcohol policy documents, evidence submissions to the Scottish Parliament's Health and Sport Committee and 36 confidential interviews with policy stakeholders (academics, advocates, industry representatives, politicians and civil servants). Findings: A range of policy actors exerted influence both directly (through Parliamentary institutions and political representatives) and indirectly through the mass media. Policy actors were acutely aware of mass media's importance in shaping public opinion and used it tactically to influence policy. They often framed messages in subtly different ways, depending on target audiences. In general, newspapers presented the policy debate in a “balanced” way, but this arguably over-represented hostile perspective and suggested greater disagreement around the evidence base than is the case. Conclusions: The roles of policy actors vary between public and policy spheres, and how messages are communicated in policy debates depends on perceived strategic advantage. PMID:26045639

    Membrane extraction was used for the removal of sulfuric acid, acetic acid, 5-hydroxymethyl furfural and furfural from corn stover hydrolyzed with dilute sulfuric acid. Microporous polypropylene hollow fiber membranes were used. The organic extractant consisted of 15% Alamine 336 in: octanol, a 50:50 mixture of oleyl alcohol:octanol or oleyl alcohol. Rapid removal of sulfuric acid, 5-hydroxymethyl and furfural was observed. The rate of acetic acid removal decreased as the pH of the hydrolysate increased. Regeneration of the organic extractant was achieved by back extraction into an aqueous phase containing NaOH and ethanol. A cleaning protocol consisting of flushing the hydrolysate compartment with NaOH and the organic phase compartment with pure organic phase enabled regeneration and reuse of the module. Ethanol yields from hydrolysates detoxified by membrane extraction using 15% Alamine 336 in oleyl alcohol were about 10% higher than those from hydrolysates detoxified using ammonium hydroxide treatment.

    Insufficient thiamine intake during heavy alcohol dependence has been well established as a precursor to alcohol-related brain damage, including Wernicke-Korsakoff syndrome. This study compared the alcohol and thiamine intakes of 35 alcohol-dependent patients upon admission for detoxification with 49 healthy young undergraduates. Subjects were interviewed using a retrospective diary that recorded alcohol and food and vitamin consumption for the previous seven days. As predicted, the clinical group consumed significantly less thiamine than the healthy group, and well below the minimum safe daily intakes. Findings have implications for the prevention of alcohol-related brain damage and public health policy. PMID:15217037

    Background: Illicit opiate use has an increasing incidence and prevalence, which increases mortality and morbidity, marginalization, and criminal behaviors, and causes major adverse effects on society. Objectives: This study aimed to investigate and follow the outcome of patients who underwent ultrarapid opiate detoxification (UROD) prospectively. Patients and Methods: In this randomized clinical trial, 64 patients who underwent UROD were evaluated. The opiate antagonist regimen of naloxone was administered intravenously under general anesthesia, and detoxification was confirmed by naloxone challenge test. All patients were cared in intensive care unit (ICU) for 24 hours, and oral naltrexone was prescribed the next day, after recovery and discharge. Patients were followed up for one month after the procedure. Relapse was considered if routine use of opiates (daily use for at least two weeks) was reported by the patient after detoxification. The data was analyzed by SPSS 16.5 and the study was performed using descriptive analysis and Chi square test. Results: All 64 participants were opiate-dependent males (ASA physical status of I or II) who aged over 18 years with a mean age of 31.11 ± 8.93 years at the time of UROD. One month after UROD, 48 patients (75%) reported relapse and 16 (25%) reported abstinence; however, four patients of the non-relapsed group reported one episode of opiate use. There was no significant difference between relapsed and non-relapsed patients regarding their marital status, level of education, and family history of opiate dependency (P > 0.05). Conclusions: Although UROD by naloxone is a safe and effective method of detoxification, if used alone, it has a very high relapse rate in long term. PMID:25741479

    The Solar Detoxification Field Experiment was designed to investigate the photocatalytic decomposition of organic contaminants in groundwater at a Superfund site at Lawrence Livermore National Laboratory. The process uses ultraviolet (UV) energy available in sunlight in conjunction with a photocatalyst, titanium dioxide, to decompose organic chemicals into nontoxic compounds. The destruction mechanism, as in many other advanced oxidation processes, involves hydroxyl radicals. The field experiment was developed by three federal laboratories: The National Renewable Energy Laboratory, Sandia National Laboratory, and Lawrence Livermore National Laboratory. The United States Department of Energy funded the experiment. Groundwater at the test site was contaminated with trichloroethylene (TCE). A factorial test series examined four separate process variables: pH, catalyst loading, flow velocity, and solar intensity. Lowering the pH from pH 7 to pH 5 had the largest single effect, presumably by minimizing interference by bicarbonate. The catalyst was found to operate more efficiently at low, e.g. ambient sunlight, UV light levels. Information from these field tests suggest that treatment costs for the solar process would be similar to those for more conventional technologies. 8 refs., 10 figs., 4 tabs.

    Objective To examine the sociodeomographic, behavioral, and psychiatric correlates of cruelty to animals in the U.S. Materials and Methods Data were derived from a nationally representative sample of adults residing in the U.S. Structured psychiatric interviews (N = 43,093) were completed by trained lay interviewers between 2001 and 2002. Personality, substance use, mood, and anxiety disorders and cruelty to animals were assessed with the Alcohol Use Disorder and Associated Disabilities Interview Schedule (DSM-IV) version. Results The lifetime prevalence of animal cruelty in U.S. adults was 1.8%. Men, African-Americans, Native-Americans/Asians, native-born Americans, persons with lower levels of income and education and adults living the western region of the U.S. reported comparatively high levels of cruelty to animals, whereas Hispanics reported comparatively low levels of such behavior. Cruelty to animals was significantly associated with all assessed antisocial behaviors. Adjusted analyses revealed strong associations between lifetime alcohol use disorders, conduct disorder, antisocial, obsessive-compulsive, and histrionic personality disorders, pathological gambling, family history of antisocial behavior, and cruelty to animals. Conclusions Cruelty to animals is associated with elevated rates observed in young, poor, men with family histories of antisocial behavior and personal histories of conduct disorder in childhood, and antisocial, obsessive-compulsive and histrionic personality disorders, and pathological gambling in adulthood. Given these associations, and the widespread ownership of pets and animals, effective screening of children, adolescents and adults for animal cruelty and appropriate mental health interventions should be deployed.

    This study examines the associations between alcohol policies and motor vehicle fatality rates from 1984 to 1995 in the United States. State policies and state characteristics variables were merged with motor vehicle fatality rates over an 11 year period and analyzed using minimum logit chi-square method and fixed effects to create a quasi time-series analysis. Laws allowing individuals to sue bars for the drunken behavior of their patrons were the policies most strongly associated with lower minor and adult fatality rates. The mandatory first offense fine was associated with lower minor fatality rates but not adult fatality rates, while minor and adult rates fell after administrative per se license suspension and anti-consumption laws for all vehicle occupants. Many other public policies evaluated were not associated with lower fatality rates. PMID:10994599

    2008-01-01

    Alcohol dependence constitutes a neuroadaptive state critical for understanding alcoholism, and various methods have been utilized to induce alcohol dependence in animals, one of which is alcohol vapor exposure. Alcohol vapor inhalation provides certain advantages over other chronic alcohol exposure procedures that share the ultimate goal of producing alcohol dependence in rats. Chronic alcohol vapor inhalation allows the experimenter to control the dose, duration, and pattern of alcohol exposure. Also, this procedure facilitates testing of somatic and motivational aspects of alcohol dependence. Chronic exposure to alcohol vapor produces increases in alcohol-drinking behavior, increases in anxiety-like behavior, and reward deficits in rats. Alcohol vapor inhalation as a laboratory protocol is flexible, and the parameters of this procedure can be adjusted to accommodate the specific aims of different experiments. This unit describes the options available to investigators using this procedure for dependence induction, when different options are more or less appropriate, and the implications of each.

    α-Tomatine and chlorophyll (a and b) decreased, and β-carotene and lycopene increased with ripening of tomatoes. α-Tomatine was localised in peel of immature green tomatoes. The dose-response curve of α-tomatine determined by WST-1 (water soluble tetrazolium) assay was the same as that by LDH (lactate dehydrogenase) assay, suggesting that the cytotoxicity of α-tomatine depends on the destruction of plasma membrane. Immature green tomatoes had little cytotoxic effect after one month-incubation with 25% ethanol or 4.5% acetate at 7°C, and α-tomatine was decomposed by crude enzymes extracted from immature green tomatoes. Immature green tomatoes incubated with 4.5% acetic acid inhibited the accumulation of lipid in adipocytes. From the above facts the detoxification and the anti-obesity effect of immature green tomatoes are expected to be controlled by the removal of peel, the enzymatic decomposition or the incubation with 4.5% acetate or 25% ethanol.

    This report describes progress on the development of engineered photocatalysts for the detoxification of water polluted with toxic organic compounds and heavy metals. We examined a range of different oxide supports (titania, alumina, magnesia and manganese dioxide) for tin uroporphyrin and investigated the efficacy of a few different porphyrins. A water-soluble octaacetic-acid-tetraphenylporphyrin and its derivatives have been synthesized and characterized in an attempt to design a porphyrin catalyst with a larger binding pocket. We have also investigated photocatalytic processes on both single crystal and powder forms of semiconducting SiC with an ultimate goal of developing a dual-semiconductor system combining TiO{sub 2} and SiC. Mathematical modeling was also performed to identify parameters that can improve the efficiency of SiC-based photocatalytic systems. Although the conceptual TiO{sub 2}/SiC photodiode shows some promises for photoreduction processes, SiC itself was found to be an inefficient photocatalyst when combined with TiO{sub 2}. Alternative semiconductors with bandgap and band potentials similar to SiC should be tested in the future for further development and a practical utilization of the dual photodiode concept.

    Addition of sodium borohydride to a lignocellulose hydrolysate of Norway spruce affected the fermentability when cellulosic ethanol was produced using Saccharomyces cerevisiae. Treatment of the hydrolysate with borohydride improved the ethanol yield on consumed sugar from 0.09 to 0.31 g/g, the balanced ethanol yield from 0.02 to 0.30 g/g, and the ethanol productivity from 0.05 to 0.57 g/(L×h). Treatment of a sugarcane bagasse hydrolysate gave similar results, and the experiments indicate that sodium borohydride is suitable for chemical in situ detoxification. The model inhibitors coniferyl aldehyde, p-benzoquinone, 2,6-dimethoxybenzoquinone, and furfural were efficiently reduced by treatment with sodium borohydride, even under mild reaction conditions (20 °C and pH 6.0). While addition of sodium dithionite to pretreatment liquid from spruce improved enzymatic hydrolysis of cellulose, addition of sodium borohydride did not. This result indicates that the strong hydrophilicity resulting from sulfonation of inhibitors by dithionite treatment was particularly important for alleviating enzyme inhibition. PMID:23567704

    Kratom (Mitragyna speciosa) has been used for medicinal and recreational purposes. It has reported analgesic, euphoric and antitussive effects via its action as an agonist at opioid receptors. It is illegal in many countries including Thailand, Malaysia, Myanmar, South Korea and Australia; however, it remains legal or uncontrolled in the UK and USA, where it is easily available over the Internet. We describe a case of kratom dependence in a 44-year-old man with a history of alcohol dependence and anxiety disorder. He demonstrated dependence on kratom with withdrawal symptoms consisting of anxiety, restlessness, tremor, sweating and cravings for the substance. A reducing regime of dihydrocodeine and lofexidine proved effective in treating subjective and objective measures of opioid-like withdrawal phenomena, and withdrawal was relatively short and benign. There are only few reports in the literature of supervised detoxification and drug treatment for kratom dependence. Our observations support the idea that kratom dependence syndrome is due to short-acting opioid receptor agonist activity, and suggest that dihydrocodeine and lofexidine are effective in supporting detoxification.

    Non-pregnant women can avoid alcohol-exposed pregnancies (AEPs) by modifying drinking and/or contraceptive practices. The purpose of this study was to estimate the number and characteristics of women in the United States who are at risk of AEPs. We analyzed data from in-person interviews obtained from a national probability sample (i.e., the National Survey of Family Growth) of reproductive-aged women conducted from January 2002 to March 2003. To be at risk of AEP, a woman had to have met the following criteria in the last month: (1) was drinking; (2) had vaginal intercourse with a man; and (3) did not use contraception. During a 1-month period, nearly 2 million U.S. women were at risk of an AEP (95 % confidence interval 1,760,079-2,288,104), including more than 600,000 who were binge drinking. Thus, 3.4 %, or 1 in 30, of all non-pregnant women were at risk of an AEP. Most demographic and behavioral characteristics were not clearly associated with AEP risk. However, pregnancy intention was strongly associated with AEP risk (prevalence ratio = 12.0, P < 0.001) because women often continued to drink even after they stopped using contraception. Nearly 2 million U.S. women are at AEP risk and therefore at risk of having children born with fetal alcohol spectrum disorders. For pregnant women and women intending a pregnancy, there is an urgent need for wider implementation of prevention programs and policy approaches that can reduce the risk for this serious public health problem.

    Individuals with HIV infection are living substantially longer on antiretroviral therapy, but hospitalization rates continue to be relatively high. We do not know how overall or diagnosis-specific hospitalization rates compare between HIV-infected and uninfected individuals or what conditions may drive hospitalization trends. Hospitalization rates among United States Veterans were calculated and stratified by HIV serostatus and principal diagnosis disease category. Because alcohol-related diagnoses (ARD) appeared to have a disproportional effect, we further stratified our calculations by ARD history. A multivariable Cox proportional hazards model was fitted to assess the relative risk of hospitalization controlling for demographic and other comorbidity variables. From 1997 to 2011, 46,428 HIV-infected and 93,997 uninfected patients were followed for 1,497,536 person-years. Overall hospitalization rates decreased among HIV-infected and uninfected patients. However, cardiovascular and renal insufficiency admissions increased for all groups while gastrointestinal and liver, endocrine, neurologic, and non-AIDS cancer admissions increased among those with an alcohol-related diagnosis. After multivariable adjustment, HIV-infected individuals with an ARD had the highest risk of hospitalization (hazard ratio 3.24, 95 % CI 3.00, 3.49) compared to those free of HIV infection and without an ARD. Still, HIV alone also conferred increased risk (HR 2.08, 95 % CI 2.04, 2.13). While decreasing overall, risk of all-cause hospitalization remains higher among HIV-infected than uninfected individuals and is strongly influenced by the presence of an ARD. PMID:25711299

    Background Treatment engagement is a well-established performance measure for the treatment of substance use disorders. This study examined whether outpatient treatment engagement is associated with a reduced likelihood of subsequent detoxification admissions. Methods This study used administrative data on treatment services received by clients in specialty treatment facilities licensed in Massachusetts. The sample consisted of 11,591 adult clients who began an outpatient treatment episode in 2006. Treatment engagement was defined as receipt of at least one treatment service within 14 days of beginning a new outpatient treatment episode and receipt of at least two additional treatment services in the next 30 days. The outcome was a subsequent detoxification admission. Multilevel survival models examined the relationship between engagement and outcomes, with time to detoxification admission as the dependent variable censored at 365 days. Results Only 35% of clients met the outpatient engagement criteria and 15% of clients had a detoxification admission within a year after beginning their outpatient treatment episode. Controlling for client demographics, insurance type, and substance use severity, clients who met the engagement criteria had a lower hazard of having a detoxification admission during the year following the index outpatient visit than those who did not engage (Hazard Ratio = 0.87, p < .01). Conclusions Treatment engagement is a useful measure for monitoring quality of care. The findings from this study could help inform providers and policy makers on ways to target care and reduce the likelihood of more intensive services. PMID:26308604

    While it has been steadily declining since the 1960s, though at a slower pace over the last 5 years, the average alcohol consumption per capita and per year in France remains one of the highest in Europe. The available general population surveys reveal that the most visible change is the type of alcohol abuse. Two emerging trends have been observed over the last ten years, and seem to be worsening: the transfer from daily drinking to weekend drinking, and the increase in isolated risk-taking related to acute alcoholization associated with more-or-less conscious inebriation episodes. These changes require adapting prevention messages, the development of alcohol risk screening strategies in emergency units and the assessment of therapeutic programs aiming at reducing the risks of alcohol consumption rather than maintaining abstinence.

    Changes in the kinetic variables of the platelet serotonin uptake, Km and Vmax, were studied in 7 male alcoholics, admitted for detoxification and in sex- and age-matched volunteers. On admission the alcoholics had lower Km values than reference subjects (p less than 0.05). During detoxification the Km values normalized. Vmax was normal throughout the study in spite of the changes in platelet count. The results of the study suggest that the affinity of serotonin to its uptake receptor is transiently increased after a period of heavy drinking.

    Antineoplastics in excreta from patients have been considered to be one of the origins of cytotoxic, carcinogenic, teratogenic, and mutagenic contaminants in surface water. Recent studies have demonstrated that antineoplastics in clinical wastewater can be detoxified by electrolysis. In this study, to develop a method for the detoxification of antineoplastics in excreta, methotrexate solution in the presence of human urine was electrolyzed and evaluated. We found that urine inhibits detoxification by electrolysis; however, this inhibition decreased by diluting urine. In urine samples, the concentrations of active chlorine generated by anodic oxidation from 0.9% NaCl solution for inactivation of antineoplastics increased in dilution-dependent and time-dependent manner. These results indicate that electrolysis with platinum-based iridium oxide composite electrode is a possible method for the detoxification of a certain antineoplastic in urine. PMID:22154144

    Cytochrome P450s and glutathione-S-transferases (GSTs) constitute two of the largest groups of enzyme families that are responsible for detoxification of exogenous molecules in plants. Their activities differ from plant to plant with respect to metabolism and substrate specificity which is one of the reasons for herbicide selectivity. In the tuber forming yam bean, the legume Pachyrhizus erosus, their activities at the microsomal level were investigated to determine the detoxification status of the plant. The breakdown of the herbicide isoproturon (IPU) to two distinct metabolites, 1-OH-IPU and monodesmethyl-IPU, was demonstrated. GST activity was determined with model substrates, but also by the catalysed formation of the fluorescent glutathione bimane conjugate. This study demonstrates for the first time microsomal detoxification activity in Pachyrhizus and the fluorescence image description of microsomal GST catalysed reaction in a legume. PMID:15540603

    This study assessed the reliability, validity, discriminative accuracy, and factor structure of the Detoxification Fear Survey Schedule (DFSS). Prevalence of detoxification fear and its correlates also were assessed. Random samples from three geographically, culturally, and racially disparate populations (N = 271) of treated opioid addicts were used. The DFSS had a test-retest r = .935 and demonstrated several indicants of validity. A briefer version (DFSS-14) showed superior psychometric properties and could identify correctly 81% of the detox fear subjects while it excluded 55% of nonfear subjects. The DFSS-14 had a replicated three-factor structure that accounted for 62.1% of total item variance in the validation sample. Factor two, probably best named dose reduction fear, was replicated in all populations. A cut-off score set at the nonfear mean is recommended for clinical use. A brief clinical interview of positive scorers quickly should eliminate false positives and, thus, efficiently identify most of those with detoxification fear. PMID:3667947

    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 present study investigated the nature of physiological cue reactivity and craving in response to alcohol cues among alcohol-dependent patients (N = 80) who were enrolled in detoxification treatment. Further, the predictive value with regard to future drinking of both the magnitude of the physiological and craving response to alcohol cues while in treatment and the degree of alcohol-cue exposure in patients' natural environment was assessed. Physiological reactivity and craving in response to experimental exposure to alcohol and soft drink advertisements were measured during detoxification treatment using heart rate variability and subjective rating of craving. Following discharge, patients monitored exposure to alcohol advertisements for five consecutive weeks with a diary and were followed up with an assessment of relapse at 5 weeks and 3 months post-discharge. The results indicated that the presence of alcohol cues such as the portrayal of the drug and drinking behaviour induced physiological cue reactivity and craving. Additionally, cue reactivity and craving were positively correlated, and cue reactivity was larger for patients with shorter histories of alcohol dependence. Further, patients reported a substantial daily exposure to alcohol cues. The magnitude of cue reactivity and the craving response to alcohol cues at baseline and degree of exposure to alcohol cues in patients' natural environment did not predict relapse. It is concluded that the presence of alcohol cues such as portrayal of alcoholic beverages and drinking behaviour induces cue reactivity and craving in alcohol dependence through a conditioned appetitive response.

    Although completion of detoxification (detox) and a successful transition from detox to substance use disorder (SUD) treatment and/or mutual-help groups are associated with better SUD outcomes, many patients do not complete detox or do not receive SUD care following detox. The purpose of this structured evidence review, summarizing data extraction on a yield of 26 articles, is to identify patient, program, and system factors associated with the outcomes of completion of alcohol detox and successful transitions from alcohol detox to SUD treatment and mutual-help group participation. The review found wide variability among studies in the rates at which patients complete a detox episode (45 to 95%) and enter SUD treatment or mutual-help groups after detox (14 to 92%). Within program factors, behavioral practices that contribute to both detox completion and transitioning to SUD care after detox entail involving the patient's family and utilizing motivational-based approaches. Such practices should be targeted at younger patients, who are less likely to complete detox. Although more studies using a randomized controlled trial design are needed, the evidence suggests that barriers to detox completion and transition to SUD care can be overcome to improve patient outcomes.

    Methanol is among the most common short-chain alcohols in fermenting fruits, the natural food and oviposition sites of the fruit fly Drosophila melanogaster. Our previous results showed that cytochrome P450 monooxygenases (CYPs) were associated with methanol detoxification in the larvae. Catalases, alcohol dehydrogenases (ADHs), esterases (ESTs) and glutathione S-transferases (GSTs) were specifically inhibited by 3-amino-1,2,4-triazole (3-AT), 4-methylpyrazole (4-MP), triphenyl phosphate (TPP) and diethylmeleate (DEM), respectively. CYPs were inhibited by piperonyl butoxide (PBO) and 1-aminobenzotriazole (1-ABT). In the present paper, the involvements of these enzymes in methanol metabolism were investigated in female and male adults by determining the combination indices of methanol and their corresponding inhibitors. When PBO, 1-ABT, 3-AT, 4-MP and TPP were individually mixed with methanol, they exhibited significant synergism to the mortality of the adults after 72h of dietary exposure. In contrast, the DEM and methanol mixture showed additive effects. Moreover, methanol exposure dramatically increased CYP activity and up-regulated mRNA expression levels of several Cyp genes. Bioassays using different strains revealed that the variation in ADH activity and RNAi-mediated knockdown of α-Est7 significantly changed LC50 values for methanol. These results suggest that CYPs, catalases, ADHs and ESTs are partially responsible for methanol elimination in adults. It seems that there are some differences in methanol metabolism between larvae and adults, but not between female and male adults. PMID:23751173

    The ability to detoxify defensive compounds of competitors provides key ecological advantages that can influence community-level processes. Although common in plants and bacteria, this type of detoxification interaction is extremely rare in animals. Here, using laboratory behavioral assays and analyses of videotaped interactions in South America, we report widespread venom detoxification among ants in the subfamily Formicinae. Across both data sets, nine formicine species, representing all major clades, used a stereotyped grooming behavior to self-apply formic acid (acidopore grooming) in response to fire ant (Solenopsis invicta and S. saevissima) venom exposure. In laboratory assays, this behavior increased the survivorship of species following exposure to S. invicta venom. Species expressed the behavior when exposed to additional alkaloid venoms, including both compositionally similar piperidine venom of an additional fire ant species and the pyrrolidine/pyrroline alkaloid venom of a Monomorium species. In addition, species expressed the behavior following exposure to the uncharacterized venom of a Crematogaster species. However, species did not express acidopore grooming when confronted with protein-based ant venoms or when exposed to monoterpenoid-based venom. This pattern, combined with the specific chemistry of the reaction of formic acid with venom alkaloids, indicates that alkaloid venoms are targets of detoxification grooming. Solenopsis thief ants, and Monomorium species stand out as brood-predators of formicine ants that produce piperidine, pyrrolidine, and pyrroline venom, providing an important ecological context for the use of detoxification behavior. Detoxification behavior also represents a mechanism that can influence the order of assemblage dominance hierarchies surrounding food competition. Thus, this behavior likely influences ant-assemblages through a variety of ecological pathways. PMID:26385230

    The transcription and protein activity of defence mechanisms such as ABC transporters, phase I and II of cellular detoxification and antioxidant enzymes can be altered in the presence of emerging contaminants such as pharmaceuticals impacting the overall detoxification mechanism. The present work aimed to characterise the effects of simvastatin on the detoxification mechanisms of embryonic stages of Danio rerio. In a first approach, constitutive transcription of key genes involved in detoxification was determined. Embryos were collected at different developmental stages, and transcription patterns of genes coding for ABC transporters, phase I and II and oxidative stress were analysed. With exception of abcc2, all genes seem to be from maternal transfer (0-2 hpf). Embryos were then exposed to different concentrations of simvastatin (5 and 50 μg/L), verapamil and MK571 (10 μM; ABC protein inhibitors) and a combination of simvastatin and ABC inhibitors. mRNA expression levels of abcb4, abcc1, abcc2, abcg2, cyp1a, cyp3a65, gst, sod, cat was evaluated. Accumulation assays to measure ABC proteins activity and activity of EROD, GST, CAT and Cu/ZnSOD, were also undertaken. Simvastatin acted as a weak inhibitor of ABC proteins and increased EROD and GST activity, whereas Cu/ZnSOD and CAT activity were decreased. Simvastatin up-regulated abcb4 and cyp3a65 transcription (both concentrations), as well as abcc1 and abcc2 at 50 μg/L, and down-regulated gst, sod, cat at 5 μg/L. In conclusion, our data revealed the interaction of simvastatin with detoxification mechanisms highlighting the importance of monitoring the presence of this emerging contaminant in aquatic environments.

    A 55-year-old man was admitted for a femur fracture; an alcohol fetor was noted on admission. The following day, the patient began to experience tremors and nervousness. Intravenous haloperidol was administered. Shortly afterwards, the patient experienced two generalized seizures and then began to experience delirium and uncontrollable agitation. The patient was diagnosed with alcohol withdrawal syndrome; high doses of intravenous midazolam were prescribed and infused. A few hours later, the patient presented signs of respiratory depression, requiring a transfer to the intensive care unit. After a review of the medical history, it was determined that the patient had been admitted on 3 previous occasions due to alcohol withdrawal and had progressed to delirium tremens after experiencing seizures. Can the risk of alcohol withdrawal syndrome and the need for prophylactic treatment be assessed on admission? Were appropriate monitoring and treatment measures employed? Would it have been possible to change his outcome? PMID:25559647

    Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in children, with prevalence rising alongside childhood obesity rates. This study aimed to characterise the habitual diet and activity behaviours of children with NAFLD compared to obese children without liver disease in the United Kingdom (UK). Twenty-four biopsy-proven paediatric NAFLD cases and eight obese controls without biochemical or radiological evidence of NAFLD completed a 24-h dietary recall, a Physical Activity Questionnaire (PAQ), a Dutch Eating Behavior Questionnaire (DEBQ) and a 7-day food and activity diary (FAD), in conjunction with wearing a pedometer. Groups were well matched for age and gender. Obese children had higher BMI z-scores (p = 0.006) and BMI centiles (p = 0.002) than participants with NAFLD. After adjusting for multiple hypotheses testing and controlling for differences in BMI, no differences in macro- or micronutrient intake were observed as assessed using either 24-h recall or 7-day FAD (p > 0.001). Under-reporting was prevalent (NAFLD 75%, Obese Control 87%: p = 0.15). Restrained eating behaviours were significantly higher in the NAFLD group (p = 0.005), who also recorded more steps per day than the obese controls (p = 0.01). In conclusion, this is the first study to assess dietary and activity patterns in a UK paediatric NAFLD population. Only a minority of cases and controls were meeting current dietary and physical activity recommendations. Our findings do not support development of specific dietary/ physical activity guidelines for children with NAFLD; promoting adherence with current general paediatric recommendations for health should remain the focus of clinical management.

    2012-01-01

    Background To assess the feasibility of a randomised controlled trial of a licensed premises intervention to reduce severe intoxication and disorder; to establish effect sizes and identify appropriate approaches to the development and maintenance of a rigorous research design and intervention implementation. Methods An exploratory two-armed parallel randomised controlled trial with a nested process evaluation. An audit of risk factors and a tailored action plan for high risk premises, with three month follow up audit and feedback. Thirty-two premises that had experienced at least one assault in the year prior to the intervention were recruited, match paired and randomly allocated to control or intervention group. Police violence data and data from a street survey of study premises’ customers, including measures of breath alcohol concentration and surveyor rated customer intoxication, were used to assess effect sizes for a future definitive trial. A nested process evaluation explored implementation barriers and the fidelity of the intervention with key stakeholders and senior staff in intervention premises using semi-structured interviews. Results The process evaluation indicated implementation barriers and low fidelity, with a reluctance to implement the intervention and to submit to a formal risk audit. Power calculations suggest the intervention effect on violence and subjective intoxication would be raised to significance with a study size of 517 premises. Conclusions It is methodologically feasible to conduct randomised controlled trials where licensed premises are the unit of allocation. However, lack of enthusiasm in senior premises staff indicates the need for intervention enforcement, rather than voluntary agreements, and on-going strategies to promote sustainability.

    Alcohol is the most frequently consumed toxic substance in the world. Low to moderate daily intake of alcohol has been shown to have beneficial effects on the cardiovascular system. In contrast, exposure to high levels of alcohol for a long period could lead to progressive cardiac dysfunction and heart failure. Cardiac dysfunction associated with chronic and excessive alcohol intake is a specific cardiac disease known as alcoholic cardiomyopathy (ACM). In spite of its clinical importance, data on ACM and how alcohol damages the heart are limited. In this review, we evaluate available evidence linking excessive alcohol consumption with heart failure and dilated cardiomyopathy. Additionally, we discuss the clinical presentation, prognosis and treatment of ACM. PMID:25228956

    Alcohol consumption is common across subpopulations in the United States. However, the health burden associated with alcohol consumption varies across groups, including those defined by demographic characteristics such as age, race/ethnicity, and gender. Large national surveys, such as the National Epidemiologic Survey on Alcohol and Related Conditions and the National Survey on Drug Use and Health, found that young adults ages 18–25 were at particularly high risk of alcohol use disorder and unintentional injury caused by drinking. These surveys furthermore identified significant variability in alcohol consumption and its consequences among racial/ethnic groups. White respondents reported the highest prevalence of current alcohol consumption, whereas alcohol abuse and dependence were most prevalent among Native Americans. Native Americans and Blacks also were most vulnerable to alcohol-related health consequences. Even within ethnic groups, there was variability between and among different subpopulations. With respect to gender, men reported more alcohol consumption and binge drinking than women, especially in older cohorts. Men also were at greater risk of alcohol abuse and dependence, liver cirrhosis, homicide after alcohol consumption, and drinking and driving. Systematic identification and measurement of the variability across demographics will guide prevention and intervention efforts, as well as future research. PMID:27159807

    Background The ability to abstain from drinking, despite incentives to imbibe, is essential to recovery from alcoholism. Methods We used an incentive conflict task to investigate ability to abstain from responding during presentations of incentive cues. Both alcoholic (n = 23) and healthy subjects (n = 22) were required to withhold responding during the simultaneous presentation of two visual stimuli in which the individual presentation allowed responding for monetary reward. Brain structures activated during performance of the task were studied using functional magnetic resonance imaging in healthy volunteers (n = 8), and changes in gray matter volume were studied in a separate group of patients (n = 29) compared with control subjects (n = 31) in regions of interest identified on functional magnetic resonance imaging. Results Abstinent alcoholic patients were severely impaired on the incentive conflict task. The impairment was greater in patients with experience of several versus a single detoxification. Healthy volunteers, during the same incentive conflict task, showed distinct patterns of brain activation (including gyrus rectus, ventromedial prefrontal cortex, and superior frontal gyrus). Reduction of gray matter volume in ventromedial prefrontal cortex and superior frontal gyrus of patients was more extensive in those with multiple detoxifications. Conclusions Performance deficits in alcoholics are associated with withdrawal-induced impairments in prefrontal subfields, which are exacerbated following repeated episodes of detoxification. Detoxification thus compromises functional and structural integrity of prefrontal cortex and may thus impair the ability to control future drinking. Performance in the incentive conflict task is a sensitive biomarker for such deficits. PMID:21612768

  6. The psychiatric management of patients with alcohol dependence.

    Alcohol dependence is a chronic, relapsing biobehavioral disease mediated by various parts of the brain, including reward systems, memory circuits, and the prefrontal cortex. It is characterized by loss of the ability to drink alcohol in moderation and continued drinking despite negative consequences. The alcohol withdrawal syndrome is a common but not universal diagnostic feature of alcohol dependence. Benzodiazepine detoxification of the alcohol withdrawal syndrome prevents the development of withdrawal seizures and delirium tremens, and makes patients more comfortable, which promotes engagement in treatment. Symptom-triggered dosing, based on a withdrawal rating scale such as the Clinical Institute Withdrawal Assessment of Alcohol Scale, Revised, is optimal for minimizing the total benzodiazepine dosage. Use of a long-acting benzodiazepine (eg, chlordiazepoxide) is preferred in uncomplicated patients. Thiamine should be administered routinely before the administration of intravenous fluids to prevent the development of Wernicke's encephalopathy and Wernicke-Korsakoff syndrome. In combination with psychosocial treatment, disulfiram, naltrexone, and acamprosate can reduce the frequency of relapse. Naltrexone may be more effective for reduction of loss of control with the first drink and cue-related craving, and acamprosate may be more effective for stabilizing the physiology of post-acute withdrawal. Disulfiram, an aversive deterrent, can be useful if administration can be monitored and tied to meaningful contingencies or when used prophylactically for situations anticipated to carry high risk of relapse. Psychiatric comorbidity, especially depression, is common and is best addressed concurrently, although definitive diagnosis may have to await a period of prolonged sobriety. Prescription of addictive substances, including benzodiazepines beyond the period of acute detoxification, should be avoided, and if necessary should be closely monitored (eg, by frequent

    The detoxification mechanism of asbestos materials was investigated through simulations and experiments. The permittivities of pure CaO and Mg3Si4O12, as quasi-asbestos materials, were measured using the cavity perturbation method. The real and imaginary parts of the relative permittivity (ɛr' and ɛr″) of CaO are functions of temperature, and numerical simulations revealed the thermal distributions in an electromagnetic field with respect to both asbestos shape and material configuration based on permittivity. Optical microscopic observation revealed that the thickness of chrysotile fibers decreased as a result of CaO heating. The heating mechanism of asbestos materials has been determined using CaO phase, and the detoxification mechanism of asbestos materials was discussed based on the heating mechanism. PMID:25463234

    It has been appreciated for a long time that enzymes exist as conformational ensembles throughout multiple stages of the reactions they catalyze, but there is renewed interest in the functional implications. The energy landscape that results from conformationlly diverse poteins is a complex surface with an energetic topography in multiple dimensions, even at the transition state(s) leading to product formation, and this represents a new paradigm. At the same time there has been renewed interest in conformational ensembles, a new paradigm concerning enzyme function has emerged, wherein catalytic promiscuity has clear biological advantages in some cases. "Useful", or biologically functional, promiscuity or the related behavior of "multifunctionality" can be found in the immune system, enzymatic detoxification, signal transduction, and the evolution of new function from an existing pool of folded protein scaffolds. Experimental evidence supports the widely held assumption that conformational heterogeneity promotes functional promiscuity. The common link between these coevolving paradigms is the inherent structural plasticity and conformational dynamics of proteins that, on one hand, lead to complex but evolutionarily selected energy landscapes and, on the other hand, promote functional promiscuity. Here we consider a logical extension of the overlap between these two nascent paradigms: functionally promiscuous and multifunctional enzymes such as detoxification enzymes are expected to have an ensemble landscape with more states accessible on multiple time scales than substrate specific enzymes. Two attributes of detoxification enzymes become important in the context of conformational ensembles: these enzymes metabolize multiple substrates, often in substrate mixtures, and they can form multiple products from a single substrate. These properties, combined with complex conformational landscapes, lead to the possibility of interesting time-dependent, or emergent

    Gaseous sulfide intrusion into seagrasses growing in sulfidic sediments causes little or no harm to the plant, indicating the presence of an unknown sulfide tolerance or detoxification mechanism. We assessed such mechanism in the seagrass Zostera marina in the laboratory and in the field with scanning electron microscopy coupled to energy dispersive X-ray spectroscopy, chromatographic and spectrophotometric methods, and stable isotope tracing coupled with a mass balance of sulfur compounds. We found that Z. marina detoxified gaseous sediment-derived sulfide through incorporation and that most of the detoxification occurred in underground tissues, where sulfide intrusion was greatest. Elemental sulfur was a major detoxification compound, precipitating on the inner wall of the aerenchyma of underground tissues. Sulfide was metabolized into thiols and entered the plant sulfur metabolism as well as being stored as sulfate throughout the plant. We conclude that avoidance of sulfide exposure by reoxidation of sulfide in the rhizosphere or aerenchyma and tolerance of sulfide intrusion by incorporation of sulfur in the plant are likely major survival strategies of seagrasses in sulfidic sediments.

    Quinclorac is a highly selective auxin-type herbicide and is widely used in the effective control of barnyard grass in paddy rice fields, improving the world's rice yield. The herbicide mode of action of quinclorac has been proposed, and hormone interactions affecting quinclorac signaling has been identified. Because of widespread use, quinclorac may be transported outside rice fields with the drainage waters, leading to soil and water pollution and other environmental health problems. In this study, we used 57K Affymetrix rice whole-genome array to identify quinclorac signaling response genes to study the molecular mechanisms of action and detoxification of quinclorac in rice plants. Overall, 637 probe sets were identified with differential expression levels under either 6 or 24 h of quinclorac treatment. Auxin-related genes such as GH3 and OsIAAs responded to quinclorac treatment. Gene Ontology analysis showed that genes of detoxification-related family genes were significantly enriched, including cytochrome P450, GST, UGT, and ABC and drug transporter genes. Moreover, real-time RT-PCR analysis showed that top candidate genes of P450 families such as CYP81, CYP709C, and CYP72A were universally induced by different herbicides. Some Arabidopsis genes of the same P450 family were up-regulated under quinclorac treatment. We conducted rice whole-genome GeneChip analysis and the first global identification of quinclorac response genes. This work may provide potential markers for detoxification of quinclorac and biomonitors of environmental chemical pollution. PMID:26483837

    Introduction Although substantive declines in motor vehicle fatalities 1980–2010 have been observed, declines by position in the vehicle and alcohol involvement have not been well elucidated. Method Analyses of FARS data use the Intrinisic Estimator (IE) to produce estimates of all age, period, and cohort effects simultaneously by position in the car and by alcohol involvement. Results Declines in MVC deaths by position in the car vary for men and women by age and cohort over time. Cohorts born before 1970 had higher risks than those born later. Analyses using proxy indicators of alcohol involvement found highest risks for those aged 16–24. By period, these risks declined more rapidly than non- alcohol related traffic fatalities. Conclusion Changes in risk patterns are consistent with evidence regarding the contributions of new technologies and public policy efforts to reduce fatalities, but gains have not been shared evenly by sex or position in the car. Practical Application Greater attention is needed to reducing deaths among older drivers and pedestrians. Gender differences should be addressed in prevention efforts aimed at reducing MVCs due to alcohol involvement. PMID:25662882

    Wallace, B C

    1990-01-01

    The paper presents data on a sample (N = 61) of crack-cocaine-dependent patients who were treated on an inpatient detoxification unit. The investigation explores adult child of an alcoholic status as a possible etiological factor in the development of addiction to crack cocaine. Data suggests the prevalence of adult child of an alcoholic (ACA) status in this population (61%). Adult child of a dysfunctional family (ACDF) status is also explored as possibly playing an important role as an antecedent or determinant of addiction. The vast majority of patients are adult children of a dysfunctional family (ACDF) of one kind or another (97%); for example, patients experienced domestic violence (25%) and physical abuse (28%). Perhaps as a result of less than ideal object relations in dysfunctional families, many patients were also diagnosed as having personality disorders (31%) or affective disorders (21%). Case vignettes augment research findings, supporting the contention that childhood development in a dysfunctional family constitutes a specific etiological factor in the development of crack cocaine dependence. The paper recommends matching crack-addicted ACAs/ACDFs to treatment modalities that address and remediate the personality and emotional problems that characterize ACAs/ACDFs. PMID:2388314

    The Drug Addiction Treatment Act of 2000 (DATA 2000) was established to create a new paradigm for medication-assisted treatment of persons with opiate addiction in the United States. Before enactment of DATA 2000, the use of opioid medications to treat patients with opioid addiction was permissible only in federally approved treatment programs, ie, "methadone clinics." The only medications permitted were Schedule II drugs (eg, methadone hydrochloride and l-alpha-acetylmethadol [LAAM]), which could only be dispensed, not prescribed. Under provisions of DATA 2000, qualified physicians in a medical office and other appropriate settings outside the opioid treatment program system may prescribe and/or dispense Schedule III, IV, and V opioid medications for treating persons with opioid addiction if such medications have been specifically approved by the US Food and Drug Administration for that indication. Opioid addiction treatment programs were commonly known as methadone clinics. Such programs now may also dispense buprenorphine hydrochloride and the buprenorphine hydrochloride-naloxone combination.

    Natural products have a long history of use in traditional medicines and their activities against different diseases have been the focus of many basic and clinical researches in past few decades. The essential oils, volatile liquid containing aroma compound from plants, are known as active ingredients in the herbal medicine. Perillyl alcohol (POH) is usually available through dietary sources and is being explored for its cancer chemoprevention, tumor growth suppression, and regression. Citrus peels are the waste product of juice manufacturing industries and have been considered as a critical problem for environmental green ecology policies for years. One of the most well-known approaches to overcome this problem is transformation of these monoterpene by the use of specific strains of bacteria or yeasts. Limonene (1-methyl-4-isopropyl-cyclohexene) is a monoterpene, as other monoterpenes consists of two isoprene units, that comprises more than 90% of citrus essential oil and it exists in many fruits and vegetables. Although, the anticancer activity of d-limonene has identified nearly two decades ago, it has recently attracted much more attention in translational medicine. In this chapter, we will overview the anticancer effects of POH and d-limonene. Later, we will address the pharmacokinetics of these compounds, highlight the signaling pathways which are targeted by these proteins, review the clinical trials which have been done for these compounds in different cancer models, and finally discuss the future directions of the research in this field that might be more applicable in future cancer therapy strategies.

    Azo dyes account for >70% of the global industrial demand (∼9 million tons). Owing to their genotoxic/carcinogenic potential, the annual disposal of ∼4,500,000 tons of dyes and/or degraded products is an environmental and socio-economic concern. In comparison to physico-chemical methods, microbe-mediated dye degradation is considered to be low-input, cost-effective and environmentally-safe. However, under different environmental conditions, interactions of chemically diverse dyes with metabolically diverse microbes produce metabolites of varying toxicity. In addition, majority of studies on microbial dye-degradation focus on decolorization with least attention towards detoxification. Therefore, the environmental significance of microbial dye detoxification research of past >3 decades is critically evaluated with reference to dye structure and the possible influence of microbial interactions in different environments. In the absence of ecosystem-based studies, the results of laboratory-based studies on dye degradation, metabolite production and their genotoxic impact on model organisms are used to predict the possible fate and consequences of azo dyes/metabolites in the environment. In such studies, the predominance of fewer numbers of toxicological assays that too at lower levels of biological organization (molecular/cellular/organismic) suggests its limited ecological significance. Based on critical evaluation of these studies the recommendations on inclusion of multilevel approach (assessment at multiple levels of biological organization), multispecies microcosm approach and native species approach in conjunction with identification of dye metabolites have been made for future studies. Such studies will bridge the gap between the fundamental knowledge on dye-microbe-environment interactions and its application to combat dye-induced environmental toxicity. Thus an environmental perspective on dye toxicity in the background of dye structure and effects of

    Alcoholic hepatitis (AH) causes great morbidity and mortality in the United States and throughout the world. Advances in therapy have proven difficult. In part, this reflects challenges in diagnosis, including the distinction between AH and acute-on-chronic liver failure. Liver biopsy is the best method to clarify the cause in circumstances whereby conflicting clinical data confound the diagnosis. All treatment of AH begins with abstinence from alcohol. All patients with AH should be given sufficient nutrition. Prednisolone has become the principal agent for treating patients with severe AH. PMID:27373613

    Rationally designed nanoparticles that can bind toxins show great promise for detoxification. However, the conventional intravenous administration of nanoparticles for detoxification often leads to nanoparticle accumulation in the liver, posing a risk of secondary poisoning especially in liver-failure patients. Here we present a liver-inspired three-dimensional (3D) detoxification device. This device is created by 3D printing of designer hydrogels with functional polydiacetylene nanoparticles installed in the hydrogel matrix. The nanoparticles can attract, capture and sense toxins, while the 3D matrix with a modified liver lobule microstructure allows toxins to be trapped efficiently. Our results show that the toxin solution completely loses its virulence after treatment using this biomimetic detoxification device. This work provides a proof-of-concept of detoxification by a 3D-printed biomimetic nanocomposite construct in hydrogel, and could lead to the development of alternative detoxification platforms.

    The non-medical (recreational) use of cannabis is common particularly among young adults. In light of the ongoing legalization debate the clinical impact of physical and psychosocial consequences of regular recreational cannabis consumption should be presented. Health consequences appear to be more pronounced the earlier the regular recreational cannabis use had been started in the individual's development. There is an increasing demand from recreational cannabis users for medical treatment of cannabis-related complaints including the cannabis withdrawal syndrome. Physical sequelae such as chronic bronchitis, cyclical hyperemesis and fertility problems are usually reversible along with abstinence. The often debilitating cannabis-related mental and cognitive complaints respond on a qualified inpatient detoxification treatment with high effect sizes (Cohen's d 0.7 -1.4). The severity of the cannabis addiction benefits sustainably from psychotherapeutic approaches and individual psychosocial counseling (Cohen's d 0,5-1,2). Currently, the actual health hazard of recreational cannabis use was evaluated by addiction experts to be significantly lower than that of tobacco or alcohol use. PMID:26800074

    The importance of direct and indirect alcohol markers to evaluate alcohol consumption in clinical and forensic settings is increasingly recognized. While some markers are used to prove abstinence from ethanol, other markers are suitable for detection of alcohol misuse. Phosphatidyl ethanol (PEth) is ranked among the latter. There is only little information about the correlation between PEth and other currently used markers (ethyl glucuronide, ethyl sulfate, carbohydrate deficient transferrin, gamma-glutamyl transpeptidase, and methanol) and about their decline during detoxification. To get more information, 18 alcohol-dependent patients in withdrawal therapy were monitored for these parameters in blood and urine for up to 19 days. There was no correlation between the different markers. PEth showed a rapid decrease at the beginning of the intervention, a slow decline after the first few days, and could still be detected after 19 days of abstinence from ethanol. PMID:23274938

    Introduction The differential associations of beer, wine, and spirit consumption on cardiovascular risk found in observational studies may be confounded by diet. We described and compared dietary intake and diet quality according to alcoholic beverage preference in European elderly. Methods From the Consortium on Health and Ageing: Network of Cohorts in Europe and the United States (CHANCES), seven European cohorts were included, i.e. four sub-cohorts from EPIC-Elderly, the SENECA Study, the Zutphen Elderly Study, and the Rotterdam Study. Harmonized data of 29,423 elderly participants from 14 European countries were analyzed. Baseline data on consumption of beer, wine, and spirits, and dietary intake were collected with questionnaires. Diet quality was assessed using the Healthy Diet Indicator (HDI). Intakes and scores across categories of alcoholic beverage preference (beer, wine, spirit, no preference, non-consumers) were adjusted for age, sex, socio-economic status, self-reported prevalent diseases, and lifestyle factors. Cohort-specific mean intakes and scores were calculated as well as weighted means combining all cohorts. Results In 5 of 7 cohorts, persons with a wine preference formed the largest group. After multivariate adjustment, persons with a wine preference tended to have a higher HDI score and intake of healthy foods in most cohorts, but differences were small. The weighted estimates of all cohorts combined revealed that non-consumers had the highest fruit and vegetable intake, followed by wine consumers. Non-consumers and persons with no specific preference had a higher HDI score, spirit consumers the lowest. However, overall diet quality as measured by HDI did not differ greatly across alcoholic beverage preference categories. Discussion This study using harmonized data from ~30,000 elderly from 14 European countries showed that, after multivariate adjustment, dietary habits and diet quality did not differ greatly according to alcoholic beverage

    Alcohol consumption is a global phenomenon, as is the resultant health, social and economic harm. The nature of these harms varies with different drinking patterns and with the societal and political responses to the burden of harm; nevertheless, alcohol-related chronic diseases have a major effect on health. Strong evidence exists for the effectiveness of different strategies to minimize this damage and those policies that target price, availability and marketing of alcohol come out best, whereas those using education and information are much less effective. However, these policies can be portrayed as anti-libertarian and so viewing them in the context of alcohol-related harm to those other than the drinker, such as the most vulnerable in society, is important. When this strategy is successful, as in Scotland, it has been possible to pass strong and effective legislation, such as for a minimum unit price for alcohol. PMID:27188823

    Purpose An update on pharmacotherapy for achieving and maintaining abstinence and mitigating hepatic damage in patients with alcoholic liver disease (ALD) is presented. Summary Currently there are limited pharmacotherapy options for managing ALD, which encompasses a broad spectrum of disorders ranging from steatosis and alcoholic hepatitis to fibrosis, cirrhosis, and hepatocellular cancer. Individual variation in the severity, presentation, and complex pathologenesis of ALD defines barriers to effective treatment. Scoring of disease severity using validated assessment instruments should guide treatment approaches; abstinence and proper nutrition continue to be the cornerstones of management. A literature search (through December 31, 2013) identified no reports of randomized controlled trials using Food and Drug Administration (FDA)-approved medications for the treatment of alcohol dependence in ALD-spectrum disorders. Disulfiram, acamprosate, and naltrexone (oral and intramuscular), while approved by FDA for treatment of alcohol dependence, are not currently approved for use in patients with ALD. Baclofen (also not FDA-approved for use in ALD) is the only medication available in the United States with demonstrated safety and efficacy in reducing alcoholic behavior that has been formally tested in clinical trials in patients with ALD. Pharmacotherapy of alcoholic hepatitis using glucocorticoids or pentoxifylline has shown promise, but these options are reserved for severe ALD only. Conclusion Although various treatments have been investigated for ALD in patients with alcoholism, complete abstinence from alcohol is currently the only recommended form of hepatoprotection for the entire spectrum of ALD diagnoses.

    The rodent liver eliminates toxic ammonia. In mammals, three enzymes (or enzyme systems) are involved in this process: glutaminase, glutamine synthetase and the urea cycle enzymes, represented by carbamoyl phosphate synthetase. The distribution of these enzymes for optimal ammonia detoxification was determined by numerical optimization. This in silico approach predicted that the enzymes have to be zonated in order to achieve maximal removal of toxic ammonia and minimal changes in glutamine concentration. Using 13 compartments, representing hepatocytes, the following predictions were generated: glutamine synthetase is active only within a narrow pericentral zone. Glutaminase and carbamoyl phosphate synthetase are located in the periportal zone in a non-homogeneous distribution. This correlates well with the paradoxical observation that in a first step glutamine-bound ammonia is released (by glutaminase) although one of the functions of the liver is detoxification by ammonia fixation. The in silico approach correctly predicted the in vivo enzyme distributions also for non-physiological conditions (e.g. starvation) and during regeneration after tetrachloromethane (CCl4) intoxication. Metabolite concentrations of glutamine, ammonia and urea in each compartment, representing individual hepatocytes, were predicted. Finally, a sensitivity analysis showed a striking robustness of the results. These bioinformatics predictions were validated experimentally by immunohistochemistry and are supported by the literature. In summary, optimization approaches like the one applied can provide valuable explanations and high-quality predictions for in vivo enzyme and metabolite distributions in tissues and can reveal unknown metabolic functions.

    Water pollution represents a threat of increasing importance to human health. Bivalve mollusks are filter-feeding organisms that can accumulate chemical and microbiological contaminants in their tissues from very low concentrations in the water or sediments. Consumption of contaminated shellfish is one of the main causes of seafood poisoning. Thus, marine bivalves are normally depurated in sterilized seawater for 48 h to allow the removal of bacteria. However, this depuration time might be insufficient to eliminate chemical contaminants from their tissues. We have developed a novel technology that accelerates up to fourfold the excretion rate of xenobiotics in bivalves by treatment with the antioxidant and glutathione (GSH) pro-drug N-acetylcysteine (NAC) during the depuration period. NAC improved dose-dependently the detoxification of the organophosphate (OP) pesticide fenitrothion in the mussel Mytilus galloprovincialis, diminishing its levels up to nearly a hundred fold compared to conventional depuration, by enhancing the glutathione S-transferase (GST) activity and inducing the GSH anabolism (GSH synthesis and reduction by glutathione reductase). Notably, this induction in GSH anabolism and GST activity was also observed in uncontaminated bivalves treated with NAC. As the GSH pathway is involved in the detoxification of many pollutants and biotoxins from harmful algal blooms, we validated this proof of principle in king scallops (Pecten maximus) that naturally accumulated the amnesic shellfish poisoning (ASP) toxin domoic acid. We illustrate here a method that enhances the elimination of organic contaminants in shellfish, opening new avenues of depuration of marine organisms. PMID:24880785

    • Background and Aims The widespread calcifuge moss Pleurozium schreberi is moderately tolerant of SO2, whereas Rhytidiadelphus triquetrus is limited to calcareous soils in regions of the UK that were strongly affected by SO2 pollution in the 20th century. The proposition that tolerance of SO2 by these terricolous mosses depends on metabolic detoxification of dissolved bisulfite was investigated. • Methods The capacities of the two mosses to accelerate loss of bisulfite from aqueous solutions of NaHSO3 were studied using DTNB [5, 5-dithio-(2-nitrobenzoic acid)] to assay bisulfite, and HPLC to assay sulfate in the incubation solutions. Incubations were performed for different durations, in the presence and absence of light, at a range of solution pH values, in the presence of metabolic inhibitors and with altered moss apoplastic Ca2+ and Fe3+ levels. • Key Results Bisulfite disappearance was markedly stimulated in the light and twice as great for R. triquetrus as for P. schreberi. DCMU, an inhibitor of photosynthetic electron chain transport, significantly reduced bisufite loss. • Conclusions Bisulfite (SO2) tolerance in these terricolous mosses involves extracellular oxidation using metabolic (photo-oxidative) energy, passive oxidation by adsorbed Fe3+ (only available to the calcifuge) and probably also internal metabolic detoxification.

    Current events across the globe necessitate rapid technological advances to combat the epidemic of nerve agent chemical weapons. Biocatalysis has emerged as a viable tool in the detoxification of organophosphorus neurotoxins, such as the chemical weapons VX and sarin. Efficient detoxification of contaminated equipment, machinery, and soils are of principal concern. This study describes the incorporation of a biocatalyst (organophosphorus hydrolase, E.C. 3.1.8.1) into conventional formulations of fire fighting foam. The capacity of fire fighting foams to decrease volatilization of contained contaminants, increase surface wettability, and control the rate of enzyme delivery to large areas makes them useful vehicles for enzyme application at surfaces. The performance of enzyme containing foams has been shown to be not only reproducible but also predictable. An empirical model provides reasonable estimations for the amounts of achievable surface decontamination as a function of the important parameters of the system. Theoretical modeling illustrates that the enzyme-containing foam is capable of extracting agent from the surface and is catalytically active at the foam-surface interface and throughout the foam itself. Biocatalytic foam has proven to be an effective, "environmentally friendly" means of surface and soil decontamination. PMID:10068213

    To protect stream organisms in an ephemeral stream at the Savannah River Site, a proposed National Pollutant Discharge Elimination System (NPDES) permit reduced the copper limit from 25 {micro}g/l to 6 {micro}g/l at Outfall H-12. Efforts to reduce copper in the wastewater and stormwater draining to this outfall did not succeed in bringing copper levels below this limit. Numerous treatment methods were considered, including traditional methods such as ion exchange and natural treatment alternatives such as constructed wetlands and peat beds, all of which act to remove copper. However, the very low target metal concentration and highly variable outfall conditions presented a significant challenge for these treatment technologies. In addition, costs and energy use for most of these alternatives were high and secondary wastes would be generated. The Savannah River National Laboratory developed an entirely new 'detoxification' approach to treat the outfall water. This simple, lower-cost detoxification system amends outfall water with natural organic matter to bind up to 25 {micro}g/l copper rather than remove it, thereby mitigating its toxicity and protecting the sensitive species in the ecosystem. The amendments are OMRI (Organic Materials Review Institute) certified commercial products that are naturally rich in humic acids and are commonly used in organic farming.

    Doctors of many specialties, including the family doctors, encounter the problems of alcohol abuse in their patients. Due to the fact that many symptoms of dangerous diseases can be masked by the fact of alcoholism, a brief doctor's visit has to be conducted with watchfulness, caution and care. Family doctors have some brief testes (such as CAGE test, AUDIT test), besides of precise anamnesis and blood chemistry, which make it easier to identify a patient with an alcohol problem. People with disabilities are more exposed to alcohol abuse since they often experience additional factors such as unemployment, social isolation and homelessness. All of the above factors foster the more frequent alcohol usage. In Poland the main treatment method of alcohol addiction is psychotherapy practiced in the rehab centers. The detoxification treatment is voluntary and free of charge even though the patients checking into those facilities are doing it against their will. They are forced to do so by entourage, family, spouse or risk of unemployment. Acamprozate is considered as a drug, run to extend abstaining from alcohol. In the past, therapy with disulfiram substance was common, but now, it is considered as unethical behaviour. In practice of medicine, a patient with alcohol addiction creates not onlya medical but also legal problems. Therefore keeping of detailed medical documentation is very important as it may become significant evidence in the future. PMID:23243928

    Furfural and 5-hydroxymethylfurfural (HMF) are the two main aldehyde compounds derived from pentoses and hexoses, respectively, during lignocellulosic biomass pretreatment. These two compounds inhibit microbial growth and interfere with subsequent alcohol fermentation. Saccharomyces cerevisiae has the in situ ability to detoxify furfural and HMF to the less toxic 2-furanmethanol (FM) and furan-2,5-dimethanol (FDM), respectively. Herein, we report that an uncharacterized gene, YNL134C, was highly up-regulated under furfural or HMF stress and Yap1p and Msn2/4p transcription factors likely controlled its up-regulated expression. Enzyme activity assays showed that YNL134C is an NADH-dependent aldehyde reductase, which plays a role in detoxification of furfural to FM. However, no NADH- or NADPH-dependent enzyme activity was observed for detoxification of HMF to FDM. This enzyme did not catalyse the reverse reaction of FM to furfural or FDM to HMF. Further studies showed that YNL134C is a broad-substrate aldehyde reductase, which can reduce multiple aldehydes to their corresponding alcohols. Although YNL134C is grouped into the quinone oxidoreductase family, no quinone reductase activity was observed using 1,2-naphthoquinone or 9,10-phenanthrenequinone as a substrate, and phylogenetic analysis indicates that it is genetically distant to quinone reductases. Proteins similar to YNL134C in sequence from S. cerevisiae and other microorganisms were phylogenetically analysed. PMID:25656244

    Alcohol is the most commonly used and abused drug in the world, and alcohol use disorders pose a tremendous burden to healthcare systems around the world. The lifetime prevalence of alcohol abuse in the United States is estimated to be around 18%, and the economic consequences of these disorders are staggering. Studies on hospitalized patients demonstrate that about one in four patients admitted to critical care units will have alcohol-related issues, and unhealthy alcohol consumption is responsible for numerous clinical problems encountered in intensive care unit (ICU) settings. Patients with alcohol use disorders are not only predisposed to developing withdrawal syndromes and other conditions that often require intensive care, they also experience a considerably higher rate of complications, longer ICU and hospital length of stay, greater resource utilization, and significantly increased mortality compared to similar critically ill patients who do not abuse alcohol. Specific disorders seen in the critical care setting that are impacted by alcohol abuse include delirium, pneumonia, acute respiratory distress syndrome, sepsis, gastrointestinal hemorrhage, trauma, and burn injuries. Despite the substantial burden of alcohol-induced disease in these settings, critical care providers often fail to identify individuals with alcohol use disorders, which can have significant implications for this vulnerable population and delay important clinical interventions.

    Alcohol withdrawal is a common clinical condition that has a variety of complications and morbidities. The manifestations can range from mild agitation to withdrawal seizures and delirium tremens. The treatments for alcohol withdrawal include benzodiazepines, anticonvulsants, beta-blockers and antihypertensives. Although benzodiazepines are presently a first-line therapy, there is controversy regarding the efficacies of these medications compared with others. Treatment protocols often involve one of two contrasting approaches: symptom-triggered versus fixed-schedule dosing of benzodiazepines. We describe these protocols in our review and examine the data supporting symptom-triggered dosing as the preferred method for most patients in withdrawal.The Clinical Institute Withdrawal Assessment for Alcohol scoring system for alcohol withdrawal streamlines care, optimizes patient management, and is the best scale available for withdrawal assessment. Quality improvement implications for inpatient management of alcohol withdrawal include increasing training for signs of withdrawal and symptom recognition, adding new hospital protocols to employee curricula, and ensuring manageable patient-to-physician and patient-to-nurse ratios.

    Translation in eukaryotes is surveilled to detect toxins and virulence factors and coupled to the induction of defense pathways. C. elegans germline-specific mutations in translation components are detected by this system to induce detoxification and immune responses in distinct somatic cells. An RNAi screen revealed gene inactivations that act at multiple steps in lipid biosynthetic and kinase pathways that act upstream of MAP kinase to mediate the systemic communication of translation-defects to induce detoxification genes. Mammalian bile acids can rescue the defect in detoxification gene induction caused by C. elegans lipid biosynthetic gene inactivations. Extracts prepared from C. elegans with translation deficits but not from wild type can also rescue detoxification gene induction in lipid biosynthetic defective strains. These eukaryotic antibacterial countermeasures are not ignored by bacteria: particular bacterial species suppress normal C. elegans detoxification responses to mutations in translation factors.

    Background Opioids have been shown to affect learning and memory processes. Different protocols of morphine withdrawal can substantially vary in their success to prevent opioid induced impairments of cognitive performance. In the present study, we report the effects of single and repetitive ultra-rapid detoxification (URD) on spatial learning and memory in morphine addicted rats. Methods Morphine (10 mg/kg) was intraperitoneally (IP) injected in male rats once a day over one week and after which they were detoxified with naloxone administration under anesthesia. For the repetitive procedure, a second one week morphine treatment with a second subsequent detoxification was performed. Control groups received an equivalent volume of saline injections. Spatial learning and memory was evaluated using the Morris water maze (MWM) task. Findings Both protocols of morphine administration resulted in a severe spatial memory impairment that could be significantly prevented by both single and repetitive URD. However, memory abilities in animals treated with repetitive URD were still significantly lower than in animals of the corresponding control group. Alterations in motor activity or sensory-motor coordination between morphine treated and control animals could be ruled out by comparing swimming speed and visible platform performances that were not different between groups. Thus, URD and, specifically single URD, can prevent the spatial memory impairments in addicted rats. Conclusion As opioid addiction is an extending and serious concern in many societies, these findings may have clinical values and therapeutic implications for patients who experience multiple opioid relapses.

  11. Mixed emotions: alcoholics' impairments in the recognition of specific emotional facial expressions.

    Facial expression recognition is a central feature of emotional and social behaviour and previous studies have found that alcoholics are impaired in this skill when presented with single emotions of differing intensities. The aim of this study was to explore biases in alcoholics' recognition of emotions when they were a mixture of two closely related emotions. The amygdala is intimately involved in encoding of emotions, especially those related to fear. In animals an increased number of withdrawals from alcohol leads to increased seizure sensitivity associated with facilitated transmission in the amygdala and related circuits. A further objective therefore was to explore the effect of previous alcohol detoxifications on the recognition of emotional facial expressions. Fourteen alcoholic inpatients were compared with 14 age and sex matched social drinking controls. They were asked to rate how much of each of six emotions (happiness, surprise, fear, sadness, disgust and anger) were present in morphed pictures portraying a mix of two of those emotions. The alcoholic group showed enhanced fear responses to all of the pictures compared to the controls and showed a different pattern of responding on anger and disgust. There were no differences between groups on decoding of sad, happy and surprised expressions. In addition the enhanced fear recognition found in the alcoholic group was related to the number of previous detoxifications. These results provide further evidence for impairment in facial expression recognition present in alcoholic patients. In addition, since the amygdala has been associated with the processing of facial expressions of emotion, particularly those of fear, the present data furthermore suggest that previous detoxifications may be related to changes within the amygdala.

    Despite findings that opioid detoxification serves little more than a palliative function, few patients who enter detoxification subsequently transition to long-term treatment. The current study evaluated intensive role induction (IRI), a strategy adapted from a single-session intervention previously shown to facilitate engagement of substance-dependent patients in drug-free treatment. IRI was delivered either alone or combined with case management (IRI+CM) to determine the capacity of each condition to enhance transition and engagement in long-term treatment of detoxification patients. Study participants were 240 individuals admitted to a 30-day buprenorphine detoxification delivered at a publicly-funded outpatient drug treatment clinic. Following clinic intake, participants were randomly assigned to IRI, IRI+CM, or standard clinic treatment (ST). Outcomes were assessed in terms of adherence and satisfaction with the detoxification program, detoxification completion, and transition and retention in treatment following detoxification. Participants who received IRI and IRI+CM attended more counseling sessions during detoxification than those who received ST (both p’s < .001). IRI, but not IRI+CM participants, were more likely to complete detoxification (p = .017), rated their counselors more favorably (p = .01), and were retained in long-term treatment for more days following detoxification (p = .005), than ST participants. The current study demonstrates that an easily administered psychosocial intervention can be effective for enhancing patient involvement in detoxification and for enabling their engagement in long-term treatment following detoxification.

    Hepatic complications are a common side-effect of alcoholism. Without the detoxification capabilities of the liver, alcohol misuse induces changes in gene and protein expression throughout the body. A global proteomics approach was used to identify these protein changes in the brain. We utilised human autopsy tissue from the superior frontal gyrus (SFG) of six cirrhotic alcoholics, six alcoholics without comorbid disease, and six non-alcoholic non-cirrhotic controls. Synaptic proteins were isolated and used in two-dimensional differential in-gel electrophoresis coupled with mass spectrometry. Many expression differences were confined to one or other alcoholic sub-group. Cirrhotic alcoholics showed 99 differences in protein expression levels from controls, of which half also differed from non-comorbid alcoholics. This may reflect differences in disease severity between the sub-groups of alcoholics, or differences in patterns of harmful drinking. Alternatively, the protein profiles may result from differences between cirrhotic and non-comorbid alcoholics in subjects’ responses to alcohol misuse. Ten proteins were identified in at least two spots on the 2D gel; they were involved in basal energy metabolism, synaptic vesicle recycling, and chaperoning. These post-translationally modified isoforms were differentially regulated in cirrhotic alcoholics, indicating a level of epigenetic control not previously observed in this disorder. PMID:21886576

    Alcohol abuse causes 79,000 deaths stemming from severe organ damage in the United States every year. Clinical manifestations of long-term alcohol abuse on the cardiac muscle include defective contractility with the development of dilated cardiomyopathy and low-output heart failure; which has poor prognosis with less than 25% survival for more than three years. In contrast, low alcohol consumption has been associated with reduced risk of cardiovascular disease, however the mechanism of this phenomenon remains elusive. The aim of this study was to determine the significance of apoptosis as a mediating factor in cardiac function following chronic high alcohol versus low alcohol exposure. Adult rats were provided 5 mM (low alcohol), 100 mM (high alcohol) or pair-fed non-alcohol controls for 4–5 months. The hearts were dissected, sectioned and stained with cresyl violet or immunohistochemically for caspase-3, a putative marker for apoptosis. Cardiomyocytes were isolated to determine the effects of alcohol exposure on cell contraction and relaxation. High alcohol animals displayed a marked thinning of the left ventricular wall combined with elevated caspase-3 activity and decreased contractility. In contrast, low alcohol was associated with increased contractility and decreased apoptosis suggesting an overall protective mechanism induced by low levels of alcohol exposure. PMID:26610584

    Background: Opioid dependence remains a significant problem in India, and of late intravenous (IV) buprenorphine use has increased in India, especially in combination with antihistamines and benzodiazepines. Its usage has many serious consequences in the form of needle-transmitted hepatitis and HIV, which is showing an increasing trend. Buprenorphine is a partial agonist at μ-opioid receptors. In tablet form (and rarely as IV), it is widely used in the treatment of opioid detoxification. We assessed the safety and efficacy of transdermal patch of buprenorphine with week long duration of action in the treatment of detoxification of IV buprenorphine dependence in view of its many advantages. Materials and Methods: Six consecutive patients with International Classification of Diseases diagnosis of Opioid Dependence Syndrome (IV buprenorphine) were given a buprenorphine patch for treatment of withdrawal symptoms after receiving consent. Severity of opioid dependence was assessed by using Severity of Opioid Dependence Questionnaire on the day of presentation. Subjective and objective rating for opioid withdrawal was done by subjective opiate withdrawal scale (SOWS) and objective opiate withdrawal scale (OOWS) prepatch and postpatch 3rd and 7th day. Buprenorphine side effect checklist was applied on a daily basis. Results: The patients had a mean age of 30 years, of whom 83.3% are males. All were educated and 50% were currently employed. All of them had additional comorbid substance use as well as a comorbid psychiatric diagnosis. Each of them received a patch of varying dosage. The patch dose used initially was based on clinical considerations alone and was fairly adequate in controlling acute withdrawal symptoms. There is a significant improvement in SOWS and OOWS while comparing the baseline (prepatch) with 3rd and 7th day (postpatch) (P ≤ 0.05). None of the patients reported any side effect with the patch. Conclusion: This study shows that transdermal

    Background: Chemical and physical pretreatment of lignocellulosic biomass improves substrate reactivity for increased microbial biofuel production, but also restricts growth via the release of furan aldehydes such as furfural and 5-hydroxymethylfurfural (5-HMF). The physiological effects of these inhibitors on thermophilic, fermentative bacteria is important to understand; especially as cellulolytic strains are being developed for consolidated bioprocessing (CBP) of lignocellulosic feedstocks. Identifying mechanisms for detoxification of aldehydes in naturally resistant strains such as Thermoanaerobacter spp. may also enable improvements in candidate CBP microorganisms. Results: T. pseudethanolicus 39E, an anaerobic, saccharolytic thermophile, was found to grow readily in the presence of 30more » mM furfural and 20 mM 5-HMF and reduce these aldehydes to their respective alcohols in situ. The proteomes of T. pseudethanolicus 39E grown in the presence or absence of 15 mM furfural were compared to identify upregulated enzymes potentially responsible for the observed reduction. A total of 225 proteins were differentially regulated in response to the 15 mM furfural treatment with 152 upregulated vs. 73 downregulated. Only 86 proteins exhibited a 2-fold change in abundance in either direction. Of these, 53 were upregulated in the presence of furfural and 33 were downregulated. Two oxidoreductases were upregulated at least 2-fold by furfural and were targeted for further investigation: Teth39_1597, encodes a predicted butanol dehydrogenase (BdhA) and Teth39_1598, a predicted aldo/keto reductase (AKR). Both genes were cloned from T. pseudethanolicus 39E, with the respective enzymes overexpressed in E. coli and specific activities determined against a variety of aldehydes. BdhA showed significant activity with all aldehydes tested, including furfural and 5-HMF, using NADPH as the cofactor. AKR also showed significant activity with NADPH, but only with four carbon butyr

    2003-01-01

    This article describes the various forms of alcoholic liver disease (ALD), with particular emphasis on cirrhosis, the form of liver disease that often is most associated with alcohol abuse and about which the most information is available. Epidemiological research has evaluated the prevalence of ALD and the factors that often contribute to the disease. Although the most potent factor in ALD is the excessive consumption of alcoholic beverages, gender and ethnic differences also account for some important variations in rates of liver disease. Mortality rates from cirrhosis have declined in the United States and some other countries since the 1970s. A number of factors may have contributed to this decline, including increased participation in treatment for alcohol problems and Alcoholics Anonymous membership, decreases in alcohol consumption, and changes in the consumption of certain types of alcoholic beverages.

    When we consider alcoholism and the alcoholic patient--the phenomenon and the human being--we usually think in out-of-date terms. The criterion for excessive consumption of alcohol has been modified by our changed pattern of life, and what would once have been regarded as modest over-drinking--in a large, closely-knit family in a rural community--and tolerated and accepted as such, is no longer compatible with the demands of our technological age, with its small family units often in cramped conditions in big cities and living a life which demands precision and dexterity at all times, an acuteness of both mental and physical faculties--whether at home, in a factory or behind the wheel of a car. And it is these very qualities which the alcoholic has lost. Doctors, therefore, must be able to detect excessive consumption of alcohol before the dire stages of days gone by are reached and, supported by psychiatrists and the use of drugs where necessary, the doctor can provide the patient with a security and identity all too often lacking in the alcoholic patient, and thus help him to break away from his dependence on alcohol.

    Organophosphates have been widely used as insecticides and chemical warfare agents. The health risks associated with these agents have necessitated the need for better detoxification and bioremediation tools. Bacterial enzymes capable of hydrolyzing the lethal organophosphate nerve agents are of special interest. Phosphotriesterase (PTE) isolated from the soil bacteria Pseudomonas diminuta displays a significant rate enhancement and substrate promiscuity for the hydrolysis of organophosphate triesters. Directed evolution and rational redesign of the active site of PTE have led to the identification of new variants with enhanced catalytic efficiency and stereoselectivity toward the hydrolysis of organophosphate neurotoxins. PTE has been utilized to protect against organophosphate poisoning in vivo. Biotechnological applications of PTE for detection and decontamination of insecticides and chemical warfare agents are developing into useful tools. In this review, the catalytic properties and potential applications of this remarkable enzyme are discussed.

    Extracorporeal devices have great promise for cleansing the body of virulence factors that are caused by venomous injuries, bacterial infections, and biological weaponry. The clinically used extracorporeal devices, such as artificial liver-support systems that are mainly based on dialysis or electrostatic interaction, are limited to remove a target toxin. Here, a liver-mimetic device is shown that consists of decellularized liver scaffold (DLS) populated with polydiacetylene (PDA) nanoparticles. DLS has the gross shape and 3D architecture of a liver, and the PDA nanoparticles selectively capture and neutralize the pore-forming toxins (PFTs). This device can efficiently and target-orientedly remove PFTs in human blood ex vivo without changing blood components or activating complement factors, showing potential application in antidotal therapy. This work provides a proof-of-principle for blood detoxification by a nanoparticle-activated DLS, and can lead to the development of future medical devices for antidotal therapy. PMID:26914158

    Patulin is a mycotoxin produced by Penicillium species which often contaminates fruit and fruit-derived products. In this work the degradation of patulin by the yeast Rhodosporidium paludigenum was studied and the toxicity of the degradation product was determined. Patulin-degrading activity of R. paludigenum was inducible by patulin; it was located within yeast cells and the enzyme did not require a dissociable cofactor. Chromatographic behavior and molecular mass of the degradation product indicated that R. paludigenum transformed patulin into desoxypatulinic acid. The degradation product was significantly less toxic to Arabidopsis thaliana and human liver cells than patulin; it was not toxic to Escherichia coli at the highest concentration tested. The detoxification activity of R. paludigenum toward patulin is a promising tool for the control of patulin contamination in food and feed. PMID:25722132

    Atmospheric pressure non-thermal dielectric barrier discharge (DBD) plasma generated by helium gas at high voltage and input power of about 50 W was first applied to detoxification of Jatropha curcas phorbol esters (J. PEs) as well as standard phorbol ester (4β-12-O-tetradecanoyl phorbol-13-acetate, TPA) in water and methanol. Plasma irradiation on the solution sample was conducted for 15 min. In aqueous solution, only 16% of TPA was degraded and complete degradation of J. PEs was observed. On the contrary, complete degradation of both TPA and J. PEs in methanol was achieved by the same plasma irradiation condition. Hydroxyl radical (•OH) generated by plasma irradiation of the solution is expected as the main radical inducing the degradation of PEs.

    The present study aimed to assess the safety and efficacy of mirtazapine in amphetamine detoxification in a 14-day randomized, placebo-controlled pilot trial in a Thai population. Subjects retained at a Specialized Probation Center, Department of Probation, Ministry of Justice, Thailand (n=20), who met DSM-IV criteria for amphetamine dependence and the inclusion criteria of the study, were randomized for either mirtazapine treatment or placebo. Efficacy was assessed by the Amphetamine Withdrawal Questionnaire (AWQ) for amphetamine withdrawal symptoms and the Montgomery-Asberg Depression rating scale (MADRS) for depression. Mirtazapine safety was assessed by interview during each follow-up period on days 3 and 14 after treatment. Nine subjects were randomized to the mirtazapine group and 11 to the placebo group. Among the initial 20 subjects, 16 (seven in the mirtazapine and nine in the placebo group) completed the study. There were significant improvements in the total AWQ score changes in the mirtazapine group versus placebo both at days 3 (P<0.005) and 14 (P<0.030). Significant improvements in favour of mirtazapine were also seen in the hyperarousal and the anxiety subscale score changes at days 3 (P<0.029) and 14 (P<0.018), respectively. No significant differences were seen (P>0.05) in the MADRS scores changes within or between the groups. Mild adverse events, such as headache, sedation, nausea and vomiting, were reported. In conclusion, despite its small sample size, this randomized, placebo-controlled pilot trial lends support to the hypothesis that mirtazapine may be an option in the meager armamentarium of amphetamine detoxification treatment.

    Whether aluminum toxicity is an apoplastic or symplastic phenomenon is still a matter of debate. Here, we found that three auxin overproducing mutants, yucca, the recessive mutant superroot2, and superroot1 had increased aluminum sensitivity, while a transfer DNA insertion mutant, xyloglucan endotransglucosylase/hydrolases15 (xth15), showed enhanced aluminum resistance, accompanied by low endogenous indole-3-acetic acid levels, implying that auxin may be involved in plant responses to aluminum stress. We used yucca and xth15 mutants for further study. The two mutants accumulated similar total aluminum in roots and had significantly reduced cell wall aluminum and increased symplastic aluminum content relative to the wild-type ecotype Columbia, indicating that altered aluminum levels in the symplast or cell wall cannot fully explain the differential aluminum resistance of these two mutants. The expression of Al sensitive1 (ALS1), a gene that functions in aluminum redistribution between the cytoplasm and vacuole and contributes to symplastic aluminum detoxification, was less abundant in yucca and more abundant in xth15 than the wild type, consistent with possible ALS1 function conferring altered aluminum sensitivity in the two mutants. Consistent with the idea that xth15 can tolerate more symplastic aluminum because of possible ALS1 targeting to the vacuole, morin staining of yucca root tip sections showed more aluminum accumulation in the cytosol than in the wild type, and xth15 showed reduced morin staining of cytosolic aluminum, even though yucca and xth15 had similar overall symplastic aluminum content. Exogenous application of an active auxin analog, naphthylacetic acid, to the wild type mimicked the aluminum sensitivity and distribution phenotypes of yucca, verifying that auxin may regulate aluminum distribution in cells. Together, these data demonstrate that auxin negatively regulates aluminum tolerance through altering ALS1 expression and aluminum distribution

    The narrow margin of requirement and toxicity for selenium makes it a difficult pollution problem to solve. Selenium bioaccumulation has been a major threat to wildlife in California and is becoming a major concern in the San Francisco Bay/Estuaries. Despite the past efforts in Se nutrition, chemistry, and remediation, its toxicity and detoxification mechanism(s) in wildlife, particularly primary producers, is still unclear, due to a lack of understanding in Se biochemistry. This is becoming a critical issue in assessing Se risk and remediation. To address this gap, the authors have been characterizing Se speciation and its linkage to detoxification mechanism(s) of two indigenous aquatic plants, duckweed (Lemna minor) and a microphyte (Chlorella). Using GT-MS analysis, they found that Chlorella monocultures transformed Se oxyanions into volatile dimethylselenide and dimethyidiselenide and into insoluble So at extremely high Se (up to 750 ppm) concentrations. This alga did not accumulate selenomethionine which is among the most toxic forms of Se to wildlife. Dimethylsulfide was also volatilized, consistent with the hypothesis that dimethylsulfide/dimethylselenide emissions share a similar biochemical pathway. Se-treated Chlorella biomass released dimethylsulfide/dimethylselenide upon alkaline hydrolysis, suggesting the presence of dimethylsulfonium and dimethylselenonium propionates. Dimethylsulfoniumpropionate is known as an osmoprotectant in marine phytoplankton and as a major contributor to global biogenic dimethylsulfide emissions. Dimethylselenoniumpropionate has not been identified previously and may be a byproduct of dimethylsulfoniumpropionate synthesis. The unusual Se tolerance of Chlorella may be due to its ability to volatilize and precipitate Se. Such activities may be utilized for in situ Se bioremediation. Similar investigations with duckweed is underway.

    Inpatient treatment has long been considered the reference in the treatment of alcoholism. It may indeed have many conceptual advantages, but practically it is a method of treatment with high costs and long waiting period. Moreover, reviews of studies evaluating effectiveness of treatment settings for alcohol dependence suggest that no significant differences exist between inpatient and outpatient programs. Therefore, it seems useful to determine indications of inpatient detoxification programs. As we may see, the choice of inpatient detox should be primarily guided by the contra-indications of outpatient detox. However, it also depends very much on patients' preference, essential to success, since they are the lead actors. Some other situations require urgent residential care, regardless of readiness to change or type of alcohol disorder underlying. PMID:22288351

    Bis(tpy)quaterthiophenes with symmetrically distributed two and four 6-bromohexyl side groups were prepared and modified by the reaction with triethylphosphine to give the corresponding ionic species. Both ionic and non-ionic bis(tpy)quaterthiophenes (unimers) were assembled with Zn(2+) and Fe(2+) ions to conjugated metallo-supramolecular polymers (MSPs), of which the ionic ones are soluble in alcohols and those derived from tetrasubstituted unimers are soluble even in water. The differences in assembly are specified between systems with (i) ionic and non-ionic unimers, (ii) Zn(2+) and Fe(2+) ion couplers, and (iii) methanol and water solvents. A substantial decrease in the stability of Fe-MSPs and a surprisingly high red shift of the luminescence band of Zn-MSPs were observed on going from methanol to aqueous solutions. PMID:26667325

    Long-term chronic alcoholism is associated with disparate and widespread residual consequences for brain functioning and behavior, and alcoholics suffer a variety of cognitive deficiencies and emotional abnormalities. Alcoholism has heterogeneous origins and outcomes, depending upon factors such as family history, age, gender, and mental or physical health. Consequently, the neuropsychological profiles associated with alcoholism are not uniform among individuals. Moreover, within and across research studies, variability among participants is substantial and contributes to characteristics associated with differential treatment outcomes after detoxification. In order to refine our understanding of alcoholism-related impaired, spared, and recovered abilities, we focus on five specific functional domains: (1) memory, (2) executive functions, (3) emotion and psychosocial skills, (4) visuospatial cognition, and (5) psychomotor abilities. The brain systems that are most vulnerable to alcoholism are the frontocerebellar and mesocorticolimbic circuitries. Over time, with abstinence from alcohol, the brain appears to become reorganized to provide compensation for structural and behavioral deficits. By relying on a combination of clinical and scientific approaches, future research will help to refine the compensatory roles of healthy brain systems, the degree to which abstinence and treatment facilitate the reversal of brain atrophy and dysfunction, and the importance of individual differences to outcome.

    Inpatient withdrawal treatment (detoxification) is common in opioid dependence, although dropout against medical advice often limits its outcome. This study aimed to assess baseline predictors of dropout from inpatient opioid detoxification with buprenorphine, including age, gender, current substance use, and type of postdetoxification planning. A retrospective hospital chart review was carried out for inpatient standard opioid detoxifications using buprenorphine taper, in a detoxification ward in Malmö, Sweden (N = 122). Thirty-four percent of patients (n = 42) dropped out against medical advice. In multivariate logistic regression, dropout was significantly associated with younger age (OR 0.93 [0.89-0.97]) and negatively predicted by inpatient postdetoxification plan (OR 0.41 [0.18-0.94]), thus favouring an inpatient plan as opposed to outpatient treatment while residing at home. Dropout was unrelated to baseline urine toxicology. In opioid detoxification, patients may benefit from a higher degree of postdetoxification planning, including transition to residential treatment, in order to increase the likelihood of a successful detoxification and treatment entry. Young opioid-dependent patients may need particular attention in the planning of detoxification. PMID:25530903

    Where alcohol industry self-regulation is the primary protection against youth exposure to alcohol advertising, independent, systematic monitoring of youth exposure can promote public awareness of and greater accountability in the industry's practices. Using commercially available databases, the Center on Alcohol Marketing and Youth has combined occurrence and audience data to calculate youth (aged 12-20 years) and adult (above the United States legal drinking age of 21 years) exposure to alcohol advertising on television and radio, in magazines and on the Internet. This research in the United States shows that alcohol companies have placed significant amounts of advertising where youth are more likely per capita to be exposed to it than adults. Further analyses by the Center have demonstrated that much of this excess exposure of youth to alcohol advertising in the United States could be eliminated if alcohol companies would adopt a threshold of 15% (roughly the proportion of 12-20-years-old in the population 12 and above) as the maximum youth audience composition for their advertising. Although adoption of such a threshold would still leave much youth exposure to alcohol marketing in such "unmeasured" activities as sponsorships, on-premise promotions and campus marketing, it would assist alcohol companies in reaching their intended audiences more efficiently while reducing overall youth exposure to their advertising.

    1985-05-14

    Alcohol substantially free of water is prepared by continuously fermenting a fermentable biomass feedstock in a fermentation unit, thereby forming an aqueous fermentation liquor containing alcohol and microorganisms. Continuously extracting a portion of alcohol from said fermentation liquor with an organic solvent system containing an extractant for said alcohol, thereby forming an alcohol-organic solvent extract phase and an aqueous raffinate. Said alcohol is separated from said alcohol-organic solvent phase. A raffinate comprising microorganisms and unextracted alcohol is returned to the fermentation unit.

    Alcohol is the most common drug used among adults in the United States. The use of alcohol is associated with an increased risk of injuries and accidents. Even a single episode of excessive drinking can lead to a negative outcome. Alcoholism and chronic use of alcohol are associated with numerous medical, psychiatric, social, and family problems. Family members, including children, exposed to a first-degree relative's alcohol problem are at risk for problems. Children of parents with alcohol addiction, for example, show higher rates of alcoholism than children who do not have parents with an alcohol addiction. It is important for social workers to keep in mind that alcohol and alcohol problems affect the health, safety, and well-being of people. PMID:23731412

    According to the 'Report on alcohol fuels policy review', published in 1979 by the US Department of Energy, cheese whey had a very low net feedstock cost/gal of ethanol produced ($0.22) and the production potential in the USA is 90 million gal ethanol/yr. Three processes are described, i.e. the Milbrew whey fermentation process using Kluyveromyces fragilis with whey of 10-15% TS under sterile or non-sterile conditions and in batch, semi-continuous or continuous operation (primarily, designed for the production of single-cell protein), the continuous Carbery process in commercial operation in Ireland (DSA 42, 7856) and the Danish process (Dansk Gaerings-industri, Copenhagen) producing edible alcohol from whey permeate, and methane from distillation wastes for use as fuel for heating the distillation units.

    Background An estimated 18 million adults in the United States meet the clinical criteria for diagnosis of alcohol abuse or alcoholism, a disorder ranked as the third leading cause of preventable death. In addition to brain pathology, heavy alcohol consumption is co-morbid with damage to major organs including heart, lungs, liver, pancreas and kidneys. Much of what is known about risk for and consequences of heavy consumption derive from rodent or retrospective human studies. The neurobiological effects of chronic intake in rodent studies may not easily translate to humans due to key differences in brain structure and organization between species, including a lack of higher-order cognitive functions, and differences in underlying prefrontal cortical neural structures that characterize the primate brain. Further, rodents do not voluntarily consume large quantities of EtOH and they metabolize it more rapidly than primates. Methods The basis of the Monkey Alcohol Tissue Research Resource (MATRR) is that nonhuman primates (NHPs), specifically monkeys, show a range of drinking excessive amounts of alcohol (>3.0 g/kg or a 12 drink equivalent/day) over long periods of time (12–30 months) with concomitant pathological changes in endocrine, hepatic and central nervous system (CNS) processes. The patterns and range of alcohol intake that monkeys voluntarily consume parallel what is observed in humans with alcohol use disorders and the longitudinal experimental design spans stages of drinking from the ethanol-naïve state to early exposure through chronic abuse. Age- and sex-matched control animals self-administer an isocaloric solution under identical operant procedures. Results The MATRR is a unique post-mortem tissue bank that provides CNS and peripheral tissues, and associated bioinformatics from monkeys that self-administer ethanol using a standardized experimental paradigm to the broader alcohol research community. Conclusions This resource provides a translational

    1982-08-01

    The self-report symptom inventory, SCL-90-R, was administered to 240 heroin addicts seeking ambulatory detoxification and 240 requesting methadone maintenance. Controlling for age, a stepwise discriminant analysis employing a backward elimination model was performed with the SCL-90-R's nine symptom factors to determine if the addicts described different levels of symptomatology. Interpersonal sensitivity and depression differentiated between the two groups; the ambulatory detoxification patients were more depressed and described less interpersonal sensitivity than the methadone maintenance patients. The results supported the contention that heroin addicts seeking ambulatory detoxification or methadone maintenance may display different symptoms. PMID:7128452

    Background Many opiate users entering British prisons require prescribed medication to help them achieve abstinence. This commonly takes the form of a detoxification regime. Previously, a range of detoxification agents have been prescribed without a clear evidence base to recommend a drug of choice. There are few trials and very few in the prison setting. This study compares dihydrocodeine with buprenorphine. Methods Open label, pragmatic, randomised controlled trial in a large remand prison in the North of England. Ninety adult male prisoners requesting an opiate detoxification were randomised to receive either daily sublingual buprenorphine or daily oral dihydrocodeine, given in the context of routine care. All participants gave written, informed consent. Reducing regimens were within a standard regimen of not more than 20 days and were at the discretion of the prescribing doctor. Primary outcome was abstinence from illicit opiates as indicated by a urine test at five days post detoxification. Secondary outcomes were collected during the detoxification period and then at one, three and six months post detoxification. Analysis was undertaken using relative risk tests for categorical data and unpaired t-tests for continuous data. Results 64% of those approached took part in the study. 63 men (70%) gave a urine sample at five days post detoxification. At the completion of detoxification, by intention to treat analysis, a higher proportion of people allocated to buprenorphine provided a urine sample negative for opiates (abstinent) compared with those who received dihydrocodeine (57% vs 35%, RR 1.61 CI 1.02–2.56). At the 1, 3 and 6 month follow-up points, there were no significant differences for urine samples negative for opiates between the two groups. Follow up rates were low for those participants who had subsequently been released into the community. Conclusion These findings would suggest that dihydrocodeine should not be routinely used for detoxification

    To investigate mechanisms predisposing to alcoholic brain damage, thiamine (vitamin B1 ), riboflavin (vitamin B2 ) and pyridoxine (vitamin B6 ) status was compared in persistent alcohol misusers (PAM) admitted for detoxification without evidence of significant brain damage, in alcoholics known to have severe chronic brain damage (BDAM), and in age, gender and ethnicity matched controls. Thus, activities of thiamine-dependent transketolase (ETK), riboflavin-dependent glutathione reductase, and pyridoxine-dependent aspartate amino transferase were assayed, together with the enzyme activities following addition of the appropriate co-factor. Twenty per cent of the PAM group had an abnormally low ETK activity and an abnormally high activation ratio, while 45% were abnormal in either one or both parameters. An additional 10% of the PAM group had an abnormally high activation ratio but normal ETK activity, as did 30% of the BDAM group. These subgroups of alcohol misusers may have increased requirements for thiamine secondary to an abnormality of the transketolase protein that may predispose such patients to alcoholic brain damage. There was no evidence of riboflavin or pyridoxine deficiency in either of the patient groups. We conclude that thiamine deficiency was commonly present in the alcoholic patients, and that a subgroup of patients may be predisposed to more severe brain damage as a consequence of abnormalities in the transketolase protein.

    Context: Alcohol dependence can lead to autonomic neuropathy resulting in increased cardiac morbidity and mortality. This has previously been evaluated using heart-rate variability. Aims: We compared sleep heart-rate variability of alcohol-dependent patients with that of healthy controls in this study. Settings and Design: This study was conducted at NIMHANS, Bangalore. A case control study design was adopted. Materials and Methods: Sleep heart-rate variability of 20 male alcohol-dependent inpatients was recorded on the 5th day after detoxification. Sleep heart-rate variability was also recorded in 18 age- and gender-matched healthy controls. Statistical Analysis: The groups were compared using t-test for continuous variables and Chi-squared test for discrete variables. Results: Both time and frequency domain measures were significantly lower in the patients as compared to the controls, indicating decreased HRV in alcohol-dependent individuals. Conclusions: Decreased HRV in alcohol dependence indicates potential autonomic neuropathy. PMID:23825854

    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.

    Objective To describe associations of antisocial behavioral syndromes, including DSM-IV antisocial personality disorder (ASPD) and conduct disorder without progression to ASPD (“CD only”), and syndromal antisocial behavior in adulthood without CD before age 15 (AABS, not a codable DSM-IV disorder), with body mass index (BMI) status in the general U.S. adult population. Methods This report is based on the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (n=43,093, response rate=81%). Respondents were classified according to whether they met criteria for ASPD, AABS, “CD only,” or no antisocial syndrome, and on current BMI status based on self-reported height and weight. Associations of antisocial syndromes with BMI status were examined using multinomial logistic regression. Results Among men, antisociality was not associated with BMI. Among women, ASPD was significantly associated with overweight and extreme obesity; AABS was associated with obesity and extreme obesity; and “CD only” was significantly associated with overweight, obesity, and extreme obesity. Conclusions Assessment of antisocial features appears warranted in overweight, obese, and extremely obese women, and assessment of BMI status appears indicated in antisocial women. Prevention and treatment guidelines for overweight and obesity may need revision to address comorbid antisociality, and interventions targeting antisociality may need to include attention to weight concerns.

    A portable magnetic separator device is being developed for a proposed magnetically based detoxification system. In this paper, the performance of this device was evaluated via preliminary in vitro flow experiments using simple fluids and a separator unit consisting of one tube and two metal wires, each at the top and bottom of the tube. The effects of the following factors were observed: mean flow velocity U(o) (0.14-45 cm s(-1)), magnetic field strength micro(o)H(o) (0.125-0.50 T), wire size R(w) (0.125, 0.250 and 0.500 mm), wire length L(w) (2, 5 and 10 cm), wire materials (nickel, stainless steel 304 and 430) and tube size (outer radius R(o) = 0.30 mm and inner radius R(i) = 0.25 mm; R(o) = 0.50 mm and R(i) = 0.375 mm; and R(o) = 2.0 mm and R(i) = 1.0 mm). Our observations showed that the experimental results fit well with the corresponding theoretical results from the model we previously developed at a low flow velocity area (for example, U(o) < or = 20 cm s(-1)), strong external magnetic field (for example, > or = 0.30 T) and long wire length (for example, L(w) = 10 cm). The experimental results also showed that more than 90% capture efficiency is indeed achievable under moderate systemic and operational conditions. Pressure drop measurements revealed that the device could work well under human physiological and clinical conditions, and sphere buildup would not have any considerable effect on the pressure drop of the device. The breakthrough experiments demonstrated that a lower flow rate V, higher applied magnetic field micro(o)H(o) and diluted sphere suspension, i.e. lower C(o), would delay the breakthrough. All the results indicate the promise of this portable magnetic separator device to efficiently in vivo sequestrate nano-/micro-spheres from blood flow in the future magnetically based detoxification system.

    Most patients with opioid addiction do not receive medication at the time of discharge from brief inpatient detoxification programs despite the high risk of relapse and the availability of three FDA-approved medications. We surveyed 164 inpatient opioid detoxification patients to assess desire for pharmacotherapy following detoxification program discharge. Participants were predominantly male (71.3%) and 80% had detoxed in the past. Reporting on their most recent previous inpatient detoxification, 27% had relapsed the day they were discharged, 65% within a month of discharge, and 90% within a year of discharge. 63% reported they wanted medication-assisted treatment (MAT) after discharge from the current admission. The odds of desiring a treatment medication increased by a factor of 1.02 for every 1% increase in perceived relapse risk (p < .01). These data suggest patient preference discussions including relapse risk could increase post-detox abstinence. PMID:23786852

    Objective To describe associations of DSM-IV antisocial personality disorder (ASPD), conduct disorder without progression to ASPD (“CD only”), and syndromal antisocial behavior in adulthood without CD before age 15 (AABS, not a DSM-IV diagnosis) with past-year physical health status and hospital care utilization in the general U.S. adult population. Methods This report is based on the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (n=43,093, response rate=81%). Respondents were classified according to whether they met criteria for ASPD, AABS, “CD only,” or no antisocial syndrome. Associations of antisocial syndromes with physical health status and care utilization were examined using normal-theory and logistic regression. Results ASPD and AABS were significantly but modestly associated with total past-year medical conditions, coronary heart and gastrointestinal diseases, and numbers of inpatient hospitalizations, inpatient days, emergency department visits, and clinically significant injuries. ASPD was also associated with liver disease, arthritis, and lower scores on the Short Form-12 version 2 (SF-12v2) Physical Component, Role Physical, and Bodily Pain Scales. AABS was associated with noncoronary heart disease, lower scores on the SF-12v2 General Health and Vitality Scales, and, among men, arthritis. “CD only” was associated with single but not multiple inpatient hospitalizations, emergency department visits, and clinically significant injuries. Conclusions Estimates of burden related to antisocial behavioral syndromes need to consider associated physical health problems. Prevention and treatment guidelines for injuries and common chronic diseases may need to address comorbid antisociality, and interventions targeting antisociality may need to consider general health status, including prevention and management of injuries and chronic diseases.

    1988-01-01

    To estimate the excess mortality due to alcohol in England and Wales death rates specific to alcohol consumption that had been derived from five longitudinal studies were applied to the current population divided into categories of alcohol consumption. Because of the J shaped relation between alcohol consumption and death the excess mortality used as a baseline was an alcohol consumption of 1-10 units/week and an adjustment was made for the slight excess mortality of abstainers. The number of excess deaths was obtained by subtracting the number of deaths expected if all the population had the consumption of the lowest risk group; correction for the total observed mortality in the population was made. This resulted in an estimate of 28,000 deaths each year in England and Wales as the excess mortality among people aged 15-74 associated with alcohol consumption. PMID:3140936

    Although current treatments for opioid detoxification are not always effective, medical detoxification remains a required step before long-term interventions. The use of opioid antagonist medications to improve detoxification has produced inconsistent results. Very low dose naltrexone (VLNTX) was recently found to reduce opioid tolerance and dependence in animal and clinical studies. We decided to evaluate safety and efficacy of VLNTX adjunct to methadone in reducing withdrawal during detoxification. In a multi-center, double-blind, randomized study at community treatment programs, where most detoxifications are performed, 174 opioid-dependent subjects received NTX 0.125 mg, 0.250 mg or placebo daily for 6 days, together with methadone in tapering doses. VLNTX-treated individuals reported attenuated withdrawal symptoms [F = 7.24 (2,170); P = 0.001] and reduced craving [F = 3.73 (2,107); P = 0.03]. Treatment effects were more pronounced at discharge and were not accompanied by a significantly higher retention rate. There were no group differences in use of adjuvant medications and no treatment-related adverse events. Further studies should explore the use of VLNTX, combined with full and partial opioid agonist medications, in detoxification and long-term treatment of opioid dependence. PMID:18715283

    2014-01-01

    Background The high cost of detoxification (detox) services and health risks associated with continued substance abuse make readmission to detox an important indicator of poor performance for substance use disorder treatment systems. This study examined the extent to which the structure of local networks available to detox programs affects patients’ odds of readmission to detox within 1 year. Methods Administrative data from 32 counties in California in 2008–2009 were used to map network ties between programs based on patient transfers. Social network analysis was employed to measure structural features of detox program networks. Contextual predictors included efficiency (proportion of ties within a network that are non-redundant) and out-degree (number of outgoing ties to other programs). A binary mixed model was used to predict the odds of readmission among detox patients in residential (non-hospital) facilities (N =18,278). Results After adjusting for patient-level covariates and continuity of service from detox to outpatient or residential treatment, network efficiency was associated with lower odds of readmission. Conclusion The impact of network structure on detox readmissions suggests that the interorganizational context in which detox programs operate may be important for improving continuity of service within substance use disorder treatment systems. Implications for future research are discussed. PMID:24529966

Discovery of novel GST and esterase inhibitors from phytochemicals could provide potential new insecticide synergists. Conifer tree species contain flavonoids, such as taxifolin, that inhibit in vitro GST activity. The objectives were to test the relative effectiveness of taxifolin as an enzyme inhibitor and as an insecticide synergist in combination with the organophosphorous insecticide, Guthion (50% azinphos-methyl), and the botanical insecticide, pyrethrum, using an insecticide-resistant Colorado potato beetle (CPB) Leptinotarsa decemlineata (Say) strain. Both taxifolin and its isomer, quercetin, increased the mortality of 1(st) instar CPB larvae after 48h when combined with Guthion, but not pyrethrum. Taxifolin had greater in vitro esterase inhibition compared with the commonly used esterase inhibitor, S, S, S-tributyl phosphorotrithioate (DEF). An in vivo esterase and GST inhibition effect after ingestion of taxifolin was measured, however DEF caused a greater suppression of esterase activity. This study demonstrated that flavonoid compounds have both in vitro and in vivo esterase inhibition, which is likely responsible for the insecticide synergism observed in insecticide-resistant CPB.

    Lignocellulose hydrolysates contain fermentation inhibitors causing decreased ethanol production. The inhibitors include phenolic compounds, furan aldehydes, and aliphatic acids. One of the most efficient methods for removing inhibiting compounds prior to fermentation is treatment of the hydrolysate with ion-exchange resins. The performance and detoxification mechanism of three different resins were examined: an anion exchanger, a cation exchanger, and a resin without charged groups (XAD-8). A dilute acid hydrolysate of spruce was treated with the resins at pH 5.5 and 10.0 prior to ethanolic fermentation with Saccharomyces cerevisiae. In addition to the experiments with hydrolysate, the effect of the resins on selected model compounds, three phenolics (vanillin, guaiacol, and coniferyl aldehyde) and two furan aldehydes (furfural and hydroxymethyl furfural), was determined. The cation exchanger increased ethanol production, but to a lesser extent than XAD-8, which in turn was less effective than the anion exchanger. Treatment at pH 10.0 was more effective than at pH 5.5. At pH 10.0, the anion exchanger efficiently removed both anionic and uncharged inhibitors, the latter by hydrophobic interactions. The importance of hydrophobic interactions was further indicated by a substantial decrease in the concentration of model compounds, such as guaiacol and furfural, after treatment with XAD-8.

    A solar-driven photocatalytic process is being developed to destroy low levels of toxic organics in water. Parabolic troughs with a glass pipe reactor and heliostats (large tracking mirrors) with a falling-film reactor were used to conduct engineering-scale solar detoxification of water experiments. We have assessed the effect of catalyst (titanium dioxide) loading and hydrogen peroxide concentration on the destruction of a model organic compound, salicylic acid. We found the optimal catalyst loading to be 0.1% for the conditions of 30 ppM salicylic acid and 300 ppM hydrogen peroxide. Hydrogen peroxide affected the reaction rates significantly, increasing the reaction rate over 4 times for stoichiometric amounts and more than 19 times for 10 times the stoichiometric amount. Destruction rates appear to be linearly proportional to the ultraviolet light intensity, though more data are needed to fully establish the relation. Initial tests with an actual water pollutant, trichloroethylene, demonstrated destruction from 1.2 ppM to less than 50 ppB in less than 5 minutes of exposure with a trough system. 15 refs., 6 figs.

    Manganese peroxidase (MnP) was produced from white rot edible mushroom Pleurotus ostreatus on the culture filtrate. The enzyme was purified to homogeneity using (NH4)2SO4 precipitation, DEAE-Sepharose and Sephadex G-100 column chromatography. The final enzyme activity achieved 81 U mL−1, specific activity 78 U mg−1 with purification fold of 130 and recovery 1.2% of the crude enzyme. SDS-PAGE indicated that the pure enzyme have a molecular mass of approximately 42 kDa. The optimum pH was between 4–5 and the optimum temperature was 25 °C. The pure MnP activity was enhanced by Mn2+, Cu2+, Ca2+ and K+ and inhibited by Hg+2 and Cd+2. H2O2 at 5 mM enhanced MnP activity while at 10 mM inhibited it significantly. The MnP-cDNA encoding gene was sequenced and determined (GenBank accession no. AB698450.1). The MnP-cDNA was found to consist of 497 bp in an Open Reading Frame (ORF) encoding 165 amino acids. MnP from P. ostreatus could detoxify aflatoxin B1 (AFB1) depending on enzyme concentration and incubation period. The highest detoxification power (90%) was observed after 48 h incubation at 1.5 U mL−1 enzyme activities. PMID:24948923

    Clays employed historically in the consumption of astringent acorns plus seven edible clays from Africa were examined in relation to the functional significance of human geophagy. On the basis of sorptive maxima for tannic acid ranging from 5.6 to 23.7 mg/g, we conclude that adsorption of tannic acid in traditional acorn preparation methods in California and Sardinia helped make these nuts palatable. Calcium available in solution at pH 2.0 and 0.1 mol NaCl/L was 2.10 and 0.71 mg/g for the Sardinian and Californian clays, respectively. The African clays released calcium, copper, iron, magnesium, manganese, or zinc in amounts of nutritional significance from some clays but not from others. A clay recovered from an archaeological site occupied by Homo erectus and early H. sapiens was indistinguishable mineralogically, in detoxification capacity and in available minerals, from clays used in Africa today. We suggest that the physiological significance of geophagy made it important in the evolution of human dietary behavior.

    As a cleanup alterative, the bioremediation potential of soil, contaminated by spills of three medium petroleum distillates, jet fuel heating oil (No. 2 fuel oil) and diesel fuel was evaluated in controlled-temperature laboratory soil columns and in outdoor lysimeters. Solvent extraction followed by gas chromatography (GC) was used routinely for analysis of fuel residues. Occasionally, class separation and GC-mass spectrometry (GC-MS) were also used in residue characterization. The decrease in toxic residues was evaluated by Microtox and Ames tests. Seed germination and plant growth bioassays were also performed. Persistence and toxicity of the fuels increased in the order of jet fuel [lt] heating oil [lt] diesel fuel. Bioremediation consisting of liming, fertilization and tilling decreased the half-lives of the pollutants in soil by a factor of 2-3. Biodegradation was faster at 27C than at 17 or 37C, but hydrocarbon concentration and soil quality had only modest influence on biodegradation rates and did not preclude successful bioremediation of these contaminated soils within one growing season. Microbial activity measurements by the fluorescein diacetate hydrolysis assay confirmed that microbial activity was the principal force in hydrocarbon elimination. Bioremediation was highly effective in eliminating also the polycyclic aromatic components of diesel fuel. The bioremediation and detoxification of fuel-contaminated soil was corroborated by Microtox, Ames and plant growth bioassays.

    Chylomicrons have been shown to protect against endotoxin-induced lethality. LPS-binding protein (LBP) is involved in the inactivation of bacterial toxin by lipoproteins. The current study examined the interaction among LBP, chylomicrons, and bacterial toxin. LBP was demonstrated to associate with chylomicrons and enhance the amount of LPS binding to chylomicrons in a dose-dependent fashion. In addition, LBP accelerated LPS binding to chylomicrons. This LBP-induced interaction of LPS with chylomicrons prevented endotoxin toxicity, as demonstrated by reduced cytokine secretion by PBMC. When postprandial circulating concentrations of chylomicrons were compared with circulating levels of low density lipoprotein, very low density lipoprotein, and high density lipoprotein, chylomicrons exceeded the other lipoproteins in LPS-inactivating capacity. Furthermore, highly purified lipoteichoic acid, an immunostimulatory component of Gram-positive bacteria, was detoxified by incubation with LBP and chylomicrons. In conclusion, our results indicate that LBP associates with chylomicrons and enables chylomicrons to rapidly bind bacterial toxin, thereby preventing cell activation. Besides a role in the detoxification of bacterial toxin present in the circulation, we believe that LBP-chylomicron complexes may be part of a local defense mechanism of the intestine against translocated bacterial toxin.

  13. Ultraviolet reflector materials for solar detoxification of hazardous waste

    1991-07-01

    Organic waste detoxification requires cleavage of carbon bonds. Such reactions can be photo-driven by light that is energetic enough to disrupt such bonds. Alternately, light can be used to activate catalyst materials, which in turn can break organic bonds. In either case, photons with wavelengths less than 400 nm are required. Because the terrestrial solar resource below 400 nm is so small (roughly 3% of the available spectrum), highly efficient optical concentrators are needed that can withstand outdoor service conditions. In the past, optical elements for solar application have been designed to prevent ultraviolet (uv) radiation from reaching the reflective layer to avoid the potentially harmful effects of such light on the collector materials themselves. This effectively forfeits the uv part of the spectrum in return for some measure of protection against optical degradation. To optimize the cost/performance benefit of photochemical reaction systems, optical materials must be developed that are not only highly efficient but also inherently stable against the radiation they are designed to concentrate. The requirements of uv optical elements in terms of appropriate spectral bands and level of reflectance are established based upon the needs of photochemical applications. Relevant literature on uv reflector materials is reviewed which, along with discussions with industrial contacts, allows the establishment of a data base of currently available materials. Although a number of related technologies exist that require uv reflectors, to date little attention has been paid to achieving outdoor durability required for solar applications. 49 refs., 3 figs.

    Inhibitory compounds that result from biomass hydrolysis are an obstacle to the efficient production of second-generation biofuels. Fermentative microorganisms can reduce compounds such as furfural and 5-hydroxymethyl furfural (HMF), but detoxification is accompanied by reduced growth rates and ethanol yields. In this study, we assess the effects of these furan aldehydes on pure and mixed yeast cultures consisting of a respiratory deficient mutant of Saccharomyces cerevisiae and wild-type Scheffersomyces stipitis using dynamic flux balance analysis. Uptake kinetics and stoichiometric equations for the intracellular reduction reactions associated with each inhibitor were added to genome-scale metabolic reconstructions of the two yeasts. Further modification of the S. cerevisiae metabolic network was necessary to satisfactorily predict the amount of acetate synthesized during HMF reduction. Inhibitory terms that captured the adverse effects of the furan aldehydes and their corresponding alcohols on cell growth and ethanol production were added to attain qualitative agreement with batch experiments conducted for model development and validation. When the two yeasts were co-cultured in the presence of the furan aldehydes, inoculums that reduced the synthesis of highly toxic acetate produced by S. cerevisiae yielded the highest ethanol productivities. The model described here can be used to generate optimal fermentation strategies for the simultaneous detoxification and fermentation of lignocellulosic hydrolysates by S. cerevisiae and/or S. stipitis.

  16. Inequality, deprivation and alcohol use.

    There are major social inequalities in health within societies. Alcohol and tobacco are major preventable causes of ill health. Using data from the United Kingdom, this paper examines the social distribution of tobacco and alcohol consumption; the role that tobacco and alcohol may play in mediating or modifying social inequalities in health; and the implications of social distribution for policies to reduce harm associated with consumption of alcohol and tobacco. In the United Kingdom, as in many other countries, there is clear inverse association between socio-economic position and consumption of cigarettes. Over the past three decades, the decline in smoking has been more rapid in men and women in higher socio-economic groups. United Kingdom suggest that among employed men and women, the prevalence of non-drinking shows an inverse association with occupational status; heavy drinking differs little; and moderate drinking is more common among those of higher socio-economic status. Smoking accounts for perhaps 25% of the social class difference in coronary heart disease (CHD) mortality, more for lung cancer, less for some other diseases. healthier patterns of drinking may contribute to the lower CHD rates of higher social classes. Although other factors are clearly important in generating social inequalities, it is important to take the social distribution of alcohol and tobacco into account when formulating policy. For cigarette consumption, there is evidence that in lower socio-economic groups demand is more sensitive to price; higher socio-economic groups are more responsive to health education. There has been less research of this nature for alcohol. Available analyses suggest that price responsiveness of heavy drinking may be greatest in young men and in those with lower incomes. A pricing strategy has important equity implications. PMID:9167283

  17. Insomnia, alcoholism and relapse.

    2003-12-01

    Insomnia and alcoholism are significantly associated in community surveys and patient samples. Insomnia occurs in 36-72% of alcoholic patients and may last for weeks to months after initiating abstinence from alcohol. Some correlates of insomnia in alcoholic patients are identical to those observed in non-alcoholic insomniacs, including anxiety and depression, tobacco smoking, and the use of alcohol to aid sleep. Other studies suggest that as the severity of alcoholism increases, so does the likelihood of insomnia in alcoholic patients. In the sleep laboratory, alcoholic patients who complain of insomnia have disrupted sleep continuity when compared to alcoholic patients without insomnia complaints. Recently sober alcoholics are also more likely than non-alcoholics to have sleep-disordered breathing and increased periodic leg movements, which might contribute to insomnia in some alcoholic patients. The co-occurrence of insomnia and alcoholism is clinically significant because alcoholism can exacerbate the adverse consequences of insomnia (e.g. mood changes and performance decrements) and because insomnia among patients entering treatment for alcoholism has been significantly associated with subsequent alcoholic relapse. Baseline polysomnographic correlates of subsequent relapse include prolonged sleep latency, decreased sleep efficiency and total sleep time, increased rapid eye movement sleep pressure, and decreased slow wave sleep. Whether treatment of insomnia in alcoholic patients reduces relapse rates is unknown, but preliminary treatment guidelines that accommodate the special characteristics of alcoholic patients are provided, with a goal to reduce daytime impairment and psychological distress.

    Radioimmunoassays were used to measure serum levels of laminin and of procollagen III peptides, both with the intact antibody and with the Fab fragments, within one week of alcohol withdrawal in 83 alcoholics admitted for detoxification and/or treatment of concomitant medical problems. All patients underwent a diagnostic liver biopsy, which revealed simple fatty liver in 22, perivenular fibrosis in 20, septal fibrosis in 21, and cirrhosis in 20. Although all three serum measurements correlated significantly with the degree of fibrosis, only the Fab radioimmunoassay of procollagen III peptides discriminated between simple fatty liver and perivenular fibrosis in a significant number of subjects.

  4. Comparison of methods for detoxification of spruce hydrolysate for bacterial cellulose production

    PubMed Central

    2013-01-01

    Background Bacterial cellulose (BC) is a nanostructured material with unique properties and wide applicability. In order to decrease the production cost of bacterial cellulose, lignocellulose-based media have considerable potential as alternative cost-effective feedstocks. However, pretreatment and enzymatic hydrolysis of lignocellulose to sugars also generate fermentation inhibitors. Detoxification of lignocellulosic hydrolysates is needed to achieve efficient production of BC. In this investigation, different methods for detoxification of spruce hydrolysate prior to production of BC were compared with respect to effects on potential inhibitors and fermentable sugars, sugar consumption, BC yield, and cell viability. The objectives were to identify efficient detoxification methods and to achieve a better understanding of the role played by different inhibitors in lignocellulosic hydrolysates. Results In a first series of experiments, the detoxification methods investigated included treatments with activated charcoal, alkali [sodium hydroxide, calcium hydroxide (overliming), and ammonium hydroxide], anion and cation ion-exchange resins, and reducing agents (sodium sulfite and sodium dithionite). A second series of detoxification experiments included enzymatic treatments (laccase and peroxidase). The potential inhibitors studied included aliphatic acids, furan aldehydes, and phenolic compounds. The best effects in the first series of detoxification experiments were achieved with activated charcoal and anion exchanger. After detoxification with activated charcoal the BC yield was 8.2 g/L, while it was 7.5 g/L in a reference medium without inhibitors. Treatments with anion exchanger at pH 10 and pH 5.5 gave a BC yield of 7.9 g/L and 6.3 g/L, respectively. The first series of experiments suggested that there was a relationship between the BC yield and phenolic inhibitors. Therefore, the second series of detoxification experiments focused on treatments with phenol

  6. BOA detoxification of four summer weeds during germination and seedling growth.

    A recent greenhouse study revealed a significant reduction of germination and growth of redroot pigweed (Amaranthus retroflexus) and common purslane (Portulaca oleracea) by rye mulch, whereas velvetleaf (Abutilon theophrasti) and common lambsquarters (Chenopodium album) were not suppressed. Since BOA detoxification by metabolic alteration may influence the relation between the benzoxazinoid content of the soil mulch and weed suppression, we tested the dynamics in BOA detoxification in different plant organs of three and 10-day-old seedlings of four warm season weeds incubated with five BOA concentrations (4, 20, 40, 80, and 200 μmol g(-1) fresh weight). In addition, germination and length of 3-day-old seedlings were measured after exposure to 0, 0.3, 1.5, 3, 6, and 15 μmol BOA. Finally, we tested the influence of the MDR translocator inhibitors verapamil, nifedipine, and the GST inhibitor ethycrynic acid on BOA accumulation and detoxification activity. Due to BOA-detoxification, all weeds were able to grow in environments with low BOA contents. At higher contents, Abutilon theophrasti and Chenopodium album had a better chance to survive because of highly active mechanisms that avoided the uptake of BOA (A. theophrasti) and of efficient detoxification activities in youngest seedlings (C. album). The interpretation of all of the data gave the following sequence of increasing sensitivity: A. theophrasti < C. album < P. oleracea ≤ A. retroflexus. The results were in agreement with recent findings of the suppression of these weeds by rye mulches and their benzoxazinoid contents. Our studies demonstrate for the first time that the detoxification of BOA influences the survival of certain weeds in environments enriched with this allelochemical. Therefore, detoxification processes affect the potential for weed suppression by soil allelochemicals in sustainable weed management. PMID:22614450

    Bioremediation is one of the milestones achieved by the biotechnological innovations. It is generating superior results in waste management such as removal of textile dyes, which are considered xenobiotic compounds and recalcitrant to biodegradation. In the present bioremedial approach, Brevibacillus laterosporus was used as an effective microbial tool to decolorize disperse dye Disperse Red 54 (DR54). Under optimized conditions (pH 7, 40°C), B. laterosporus led to 100% decolorization of DR54 (at 50 mg L(-1)) within 48 h. Yeast extract and peptone, supplemented in medium enhanced the decolorization efficiency of the bacterium. During the decolorization process, activities of enzymes responsible for decolorization, such as tyrosinase, veratryl alcohol oxidase and NADH--DCIP reductase were induced by 1.32-, 1.51- and 4.37-fold, respectively. The completely different chromatographic/spectroscopic spectrum of metabolites obtained after decolorization confirmed the biodegradation of DR54 as showed by High pressure liquid chromatography, High pressure thin layer chromatography and Fourier transform infrared spectroscopy. Gas chromatography-Mass spectroscopy studies suggested the parent dye was biodegraded into simple final product, N-(1λ(3)-chlorinin-2-yl)acetamide. Phytotoxicity study suggested that the metabolites obtained after biodegradation of DR54 were non-toxic as compared to the untreated dye signifying the detoxification of the DR54 by B. laterosporus.

    Quality of life (QoL) in patients admitted to a general hospital was compared with those admitted to a detoxification unit for the treatment of substance use disorder (SUD). This study combines data from two separate data collections: a cross-sectional study in a general hospital unit (somatic sample, N = 519) and a follow-up study in a detoxification unit (SUD sample, N = 140). A total of 659 patients recruited during 2008–2013 were included in this study. All patients completed a generic QoL questionnaire at inclusion, and the SUD sample also completed it at the six-month follow-up. SUD patients experienced comparably low physical QoL and had significantly lower psychological, social, and existential QoL domain scores when compared with the somatic sample. Mental distress and having a SUD were the major factors explaining variations in QoL, with both influencing QoL negatively. In the SUD sample, QoL improved moderately at the six-month follow-up with less improvement for the domain relationship to a partner. To facilitate the recovery of SUD patients, clinicians must view their patients’ situation holistically and invest efforts into the different life domains affected by poor QoL. PMID:27226719

    Platinum drug delivery against the detoxification of cytoplasmic thiols is urgently required for achieving efficacy in breast cancer treatment that is over expressed by glutathione (GSH, thiol-oligopeptide). GSH-resistant polymer-cisplatin core-shell nanoparticles were custom designed based on biodegradable carboxylic functional polycaprolactone (PCL)-block-poly(ethylene glycol) diblock copolymers. The core of the nanoparticle was fixed as 100 carboxylic units and the shell part was varied using various molecular weight poly(ethylene glycol) monomethyl ethers (MW of PEGs = 100-5000 g mol(-1)) as initiator in the ring-opening polymerization. The complexation of cisplatin aquo species with the diblocks produced core-shell nanoparticles of 75 nm core with precise size control the particles up to 190 nm. The core-shell nanoparticles were found to be stable in saline solution and PBS and they exhibited enhanced stability with increase in the PEG shell thickness at the periphery. The hydrophobic PCL layer on the periphery of the cisplatin core behaved as a protecting layer against the cytoplasmic thiol residues (GSH and cysteine) and exhibited <5% of drug detoxification. In vitro drug-release studies revealed that the core-shell nanoparticles were ruptured upon exposure to lysosomal enzymes like esterase at the intracellular compartments. Cytotoxicity studies were performed both in normal wild-type mouse embryonic fibroblast cells (Wt-MEFs), and breast cancer (MCF-7) and cervical cancer (HeLa) cell lines. Free cisplatin and polymer drug core-shell nanoparticles showed similar cytotoxicity effects in the HeLa cells. In MCF-7 cells, the free cisplatin drug exhibited 50% cell death whereas complete cell death (100%) was accomplished by the polymer-cisplatin core-shell nanoparticles. Confocal microscopic images confirmed that the core-shell nanoparticles were taken up by the MCF-7 and HeLa cells and they were accumulated both at the cytoplasm as well at peri

    Although drinking problems are now well documented in adolescents and young people, few data are available on alcohol use in children younger than 12. In France, studies have shown that 60-70% of 11-year-olds reported having tasted alcohol drinks, 4-7% having experienced drunkenness at least once, and that 5-8% might be regarded as "regular" alcohol users. By comparison, the prevalence of child drinking in the United States seems to be lower. All studies show that parental alcohol-specific attitudes and parental educational practices have a strong influence on the initiation of alcohol use in children. Some of them also indicate that early-onset drinking in children may be related to psychosocial functioning in other life areas, such as problem behaviors, low school engagement, and poor relationships with parents, in association with temperamental and environmental risk factors similar to those described in substance use disorders. Since epidemiological studies showed that early initiation of alcohol use is linked to later alcohol-related problems, these data call for further attention to children's perceptions and attitudes with respect to alcohol in research to prevent alcohol misuse.

    Release of textile azo dyes to the environment is an issue of health concern while the use of microorganisms has proved to be the best option for remediation. Thus, in the present study, a bacterial consortium consisting of Providencia rettgeri strain HSL1 and Pseudomonas sp. SUK1 has been investigated for degradation and detoxification of structurally different azo dyes. The consortium showed 98-99 % decolorization of all the selected azo dyes viz. Reactive Black 5 (RB 5), Reactive Orange 16 (RO 16), Disperse Red 78 (DR 78) and Direct Red 81 (DR 81) within 12 to 30 h at 100 mg L(-1) concentration at 30 ± 0.2 °C under microaerophilic, sequential aerobic/microaerophilic and microaerophilic/aerobic processes. However, decolorization under microaerophilic conditions viz. RB 5 (0.26 mM), RO 16 (0.18 mM), DR 78 (0.20 mM) and DR 81 (0.23 mM) and sequential aerobic/microaerophilic processes viz. RB 5 (0.08 mM), RO 16 (0.06 mM), DR 78 (0.07 mM) and DR 81 (0.09 mM) resulted into the formation of aromatic amines. In distinction, sequential microaerophilic/ aerobic process doesn't show the formation of amines. Additionally, 62-72 % reduction in total organic carbon content was observed in all the dyes decolorized broths under sequential microaerophilic/aerobic processes suggesting the efficacy of method in mineralization of dyes. Notable induction within the levels of azoreductase and NADH-DCIP reductase (97 and 229 % for RB 5, 55 and 160 % for RO 16, 63 and 196 % for DR 78, 108 and 258 % for DR 81) observed under sequential microaerophilic/aerobic processes suggested their critical involvements in the initial breakdown of azo bonds, whereas, a slight increase in the levels of laccase and veratryl alcohol oxidase confirmed subsequent oxidation of formed amines. Also, the acute toxicity assay with Daphnia magna revealed the nontoxic nature of the dye-degraded metabolites under sequential microaerophilic/aerobic processes.

    Release of textile azo dyes to the environment is an issue of health concern while the use of microorganisms has proved to be the best option for remediation. Thus, in the present study, a bacterial consortium consisting of Providencia rettgeri strain HSL1 and Pseudomonas sp. SUK1 has been investigated for degradation and detoxification of structurally different azo dyes. The consortium showed 98-99 % decolorization of all the selected azo dyes viz. Reactive Black 5 (RB 5), Reactive Orange 16 (RO 16), Disperse Red 78 (DR 78) and Direct Red 81 (DR 81) within 12 to 30 h at 100 mg L-1 concentration at 30 ± 0.2 °C under microaerophilic, sequential aerobic/microaerophilic and microaerophilic/aerobic processes. However, decolorization under microaerophilic conditions viz. RB 5 (0.26 mM), RO 16 (0.18 mM), DR 78 (0.20 mM) and DR 81 (0.23 mM) and sequential aerobic/microaerophilic processes viz. RB 5 (0.08 mM), RO 16 (0.06 mM), DR 78 (0.07 mM) and DR 81 (0.09 mM) resulted into the formation of aromatic amines. In distinction, sequential microaerophilic/ aerobic process doesn’t show the formation of amines. Additionally, 62-72 % reduction in total organic carbon content was observed in all the dyes decolorized broths under sequential microaerophilic/aerobic processes suggesting the efficacy of method in mineralization of dyes. Notable induction within the levels of azoreductase and NADH-DCIP reductase (97 and 229 % for RB 5, 55 and 160 % for RO 16, 63 and 196 % for DR 78, 108 and 258 % for DR 81) observed under sequential microaerophilic/aerobic processes suggested their critical involvements in the initial breakdown of azo bonds, whereas, a slight increase in the levels of laccase and veratryl alcohol oxidase confirmed subsequent oxidation of formed amines. Also, the acute toxicity assay with Daphnia magna revealed the nontoxic nature of the dye-degraded metabolites under sequential microaerophilic/aerobic processes.

    Objectives: The aim of this research was to study the socio-demographic and behavioral determinants of obesity and Body Mass Index (BMI) in the United States, using a nationally representative sample. Methods: We used data from the 2010 US National Health Interview Survey. Analyses were limited to adults 18 years and older (N=23,434). Multivariate regression analyses were conducted to estimate the associations between covariates and obesity and BMI. Results: Overall, 28.1% in the sample were obese and the mean BMI was 27.6 kg/m2. In adjusted models, we found that older age, non-Hispanic Black race, lower education and income levels, Midwestern and Southern region of residence, former smoking, infrequent alcohol use, physical inactivity, consumption of less fruits, vegetables, brown rice and more cheese, fried potato and meat, were associated with obesity. These factors were also associated with higher BMI, along with male gender and higher consumption of meat, fried potatoes and cheese. Conclusions and Global Health Implications: The association of many of the socio-demographic and behavioral factors with obesity and higher BMI found in our study was consistent with previous findings. Persistence of such associations suggest a need for better understanding of the underlying mechanism as well as for evaluation of the current programs and policies targeted at reducing the obesity burden in the United States. In view of the rising global obesity epidemic, especially in the low- and middle-income countries, our findings could help guide development of effective health and social policies and programs aimed at reducing the obesity burden in other parts of the world.

    Anopheles sinensis is the most important vector of malaria in Southeast Asia, including China. Currently, the most effective measure to prevent malaria transmission relies on vector control through the use of insecticides, primarily pyrethroids. Extensive use of insecticides poses strong selection pressure on mosquito populations for resistance. Resistance to insecticides can arise due to mutations in the insecticide target site (target site resistance), which in the case of pyrethroids is the para-type sodium channel gene, and/or the catabolism of the insecticide by detoxification enzymes before it reaches its target (metabolic detoxification resistance). In this study, we examined deltamethrin resistance in An. sinensis from China and investigated the relative importance of target site versus metabolic detoxification mechanisms in resistance. A high frequency (>85%) of nonsynonymous mutations in the para gene was found in populations from central China, but not in populations from southern China. Metabolic detoxification as measured by the activity of monooxygenases and glutathione S-transferases (GSTs) was detected in populations from both central and southern China. Monooxygenase activity levels were significantly higher in the resistant than the susceptible mosquitoes, independently of their geographic origin. Stepwise multiple regression analyses in mosquito populations from central China found that both knockdown resistance (kdr) mutations and monooxygenase activity were significantly associated with deltamethrin resistance, with monooxygenase activity playing a stronger role. These results demonstrate the importance of metabolic detoxification in pyrethroid resistance in An. sinensis, and suggest that different mechanisms of resistance could evolve in geographically different populations.

    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.

    Rhizobia are recognized to establish N2-fixing symbiotic interactions with legume plants. Bradyrhizobium japonicum, the symbiont of soybeans, can denitrify and grow under free-living conditions with nitrate (NO3 (-)) or nitrite (NO2 (-)) as sole nitrogen source. Unlike related bacteria that assimilate NO3 (-), genes encoding the assimilatory NO3 (-) reductase (nasC) and NO2 (-) reductase (nirA) in B. japonicum are located at distinct chromosomal loci. The nasC gene is located with genes encoding an ABC-type NO3 (-) transporter, a major facilitator family NO3 (-)/NO2 (-) transporter (NarK), flavoprotein (Flp) and single-domain haemoglobin (termed Bjgb). However, nirA clusters with genes for a NO3 (-)/NO2 (-)-responsive regulator (NasS-NasT). In the present study, we demonstrate NasC and NirA are both key for NO3 (-) assimilation and that growth with NO3 (-), but not NO2 (-) requires flp, implying Flp may function as electron donor to NasC. In addition, bjgb and flp encode a nitric oxide (NO) detoxification system that functions to mitigate cytotoxic NO formed as a by-product of NO3 (-) assimilation. Additional experiments reveal NasT is required for NO3 (-)-responsive expression of the narK-bjgb-flp-nasC transcriptional unit and the nirA gene and that NasS is also involved in the regulatory control of this novel bipartite assimilatory NO3 (-)/NO2 (-) reductase pathway.

    The Microtox assay represents a rapid, accurate, and reproducible method for determining general microbial toxicity. This assay was used to evaluate the relative toxicity of a variety of hydrolysate samples derived from dilute-acid and alkaline biomass pretreatment. Toxicity is elicited from biomass degradation products, such as furfural, hydroxymethyl furfural, and acetic acid, generated during pretreatment. Microtox results indicate that the pretreatment samples examined ranged from 9 to 71 toxicity units (TU). Correlations of TU and sample absorbance at several wavelengths were evaluated for all sample series. Sample TU values best agreed with absorbance at 230 nm, but the unsatisfactory fit suggests that absorbance should not be used as an absolute measure of sample toxicity. Microtox data for pretreatment hydrolysate samples were correlated with the inhibition experienced by the ethanologenic yeast, Saccharomyces cerevisiae strain D{sub 5}A, during the simultaneous saccharification and fermentation (SSF) process of pretreated biomass. None of the alkaline pretreatment conditions produced inhibition during SSF. However, the acid pretreatment conditions did produce a wide range of inhibitory and noninhibitory hydrolysates. In general, fermentation was inhibited for acid-pretreated hydrolysate samples with values exceeding 45 TU. Preliminary studies that focused on reducing hydrolysate sample toxicity (detoxification) indicate that adding perlite and zeolite had little effect. However, the use of charcoal, a universal flocculent, or ion-exchange resins significantly reduced sample toxicity, holding promise for the efficient bioconversion of pretreated biomass to ethanol. Moreover, the developed toxicity measurement assay can quickly monitor the quality of the pretreatment process. In this way, biomass conversion operation processes can be reliably controlled at the pilot and commercial scales. 4 refs., 4 figs., 3 tabs.

    Alcohol dependence and abuse is one of the most costly health problems in the world from both a social and an economic point of view. It is a widespread problem, focusing attention not only psychiatrists but also doctors of other specialties. Patterns of drinking appear to be changing throughout the world, with more women and young people drinking heavily. Even risky drinking is a potential health risk, while chronic alcohol abuse contribute to the serious physical and mental complications. Alcohol used disorders associated with alcohol-induced brain damage include: withdrawal state, delirium tremens, alcoholic hallucinosis, alcoholic paranoia, Korsakoffs psychosis, alcoholic dementia, alcoholic depression. On the other hand, mental disorders as panic disorder, social anxiety disorder, agoraphobia, depression, bipolar disorder, schizophrenia, personality disorder most frequently comorbid with alcohol abuse or they trigger alcohol.

    The effects of alcohol on induction of arrhythmias is dose-dependent, independent of preexisting cardiovascular diseases or heart failure and can affect otherwise healthy subjects. While the probability of atrial fibrillation increases with the alcohol dosage, events of sudden cardiac death are less frequent with low and moderate consumption but occur more often in heavy drinkers with alcoholic cardiomyopathy. Men are first affected at higher dosages of alcohol but women can suffer from arrhythmias at lower dosages. Thromboembolisms and ischemic stroke can occur less often at lower dosages of alcohol; however, hemorrhagic stroke and subarachnoid hemorrhage are increased with higher alcohol dosages. Recognizable protective mechanisms of alcohol with respect to cardiovascular diseases only occur with lower amounts of alcohol of less than 10 g per day. Underlying mechanisms explain these controversial effects. Specific therapeutic options for alcohol-related arrhythmias apart from abstinence from alcohol consumption are not known. PMID:27582366

    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.

    An integrated detoxification process with electrodialysis (ED) followed by adsorption was performed to remove fermentation inhibitors from hemicellulose hydrolysates. The hydrolysates were prepared by oxalic acid pretreatment of yellow poplars at different temperatures. Of fermentation inhibitors, acetic acid showed high removal efficiency of about 90% and high transport rate during the ED process without membrane fouling. The integration of the detoxification processes increased up to the ethanol yield of 0.33g/g sugar, the ethanol production of about 9g/L, and the productivity of 0.12g/Lh, while the fermentation of non-detoxified hydrolysates did not produce bioethanol. The influence of inhibitor concentration on the fermentability showed that HMF had the highest inhibition effect. The results clearly showed that an integrated detoxification process with ED followed by adsorption removed fermentation inhibitors with high efficiency and increased the fermentability of the oxalic acid pretreated hemicellulose hydrolysates.

    Insecticides are thought to be among the major factors contributing to current declines in bee populations. However, detoxification mechanisms in healthy, unstressed honey bees are poorly characterised. Alkaloids are naturally encountered in pollen and nectar, and we used nicotine as a model compound to identify the mechanisms involved in detoxification processes in honey bees. Nicotine and neonicotinoids have similar modes of action in insects. Our metabolomic and proteomic analyses show active detoxification of nicotine in bees, associated with increased energetic investment and also antioxidant and heat shock responses. The increased energetic investment is significant in view of the interactions of pesticides with diseases such as Nosema spp which cause energetic stress and possible malnutrition. Understanding how healthy honey bees process dietary toxins under unstressed conditions will help clarify how pesticides, alone or in synergy with other stress factors, lead to declines in bee vitality.

    Alcohol consumption and its abuse is a major health problem resulting in significant healthcare cost in the United States. Chronic alcoholism results in damage to most of the vital organs in the human body. Among the alcohol-induced injuries, alcoholic liver disease is one of the most prevalent in the United States. Remarkably, ethanol alters expression of a wide variety of microRNAs that can regulate alcohol-induced complications or dysfunctions. In this review, we will discuss the role of microRNAs in alcoholic pancreatitis, alcohol-induced liver damage, intestinal epithelial barrier dysfunction, and brain damage including altered hippocampus structure and function, and neuronal loss, alcoholic cardiomyopathy, and muscle damage. Further, we have reviewed the role of altered microRNAs in the circulation, teratogenic effects of alcohol, and during maternal or paternal alcohol consumption. PMID:26610589

    Background Many opiate users require prescribed medication to help them achieve abstinence, commonly taking the form of a detoxification regime. In UK prisons, drug users are nearly universally treated for their opiate use by primary care clinicians, and once released access GP services where 40% of practices now treat drug users. There is a paucity of evidence evaluating methadone and buprenorphine (the two most commonly prescribed agents in the UK) for opiate detoxification. Aim To evaluate whether buprenorphine or methadone help to achieve drug abstinence at completion of a reducing regimen for heroin users presenting to UK prison health care for detoxification. Design Open-label, pragmatic, randomised controlled trial in three prison primary healthcare departments in the north of England. Method Prisoners (n = 306) using illicit opiates were recruited and given daily sublingual buprenorphine or oral methadone, in the context of routine care, over a standard reduced regimen of not more than 20 days. The primary outcome measure was abstinence from illicit opiates at 8 days post detoxification, as indicated by urine test (self-report/clinical notes where urine sample was not feasible). Secondary outcomes were also recorded. Results Abstinence was ascertained for 73.7% at 8 days post detoxification (urine sample = 52.6%, self report = 15.2%, clinical notes = 5.9%). There was no statistically significant difference in the odds of achieving abstinence between methadone and buprenorphine (odds ratio [OR] = 1.69; 95% confidence interval [CI] = 0.81 to 3.51; P = 0.163). Abstinence was associated solely with whether or not the participant was still in prison at that time (15.22 times the odds; 95% CI = 4.19 to 55.28). The strongest association for lasting abstinence was abstinence at an earlier time point. Conclusion There is equal clinical effectiveness between methadone and buprenorphine in achieving abstinence from opiates at 8 days post detoxification within prison

    Objective: Alcohol addiction too often remains insufficiently treated. It shows the same profile as severe chronic diseases, but no comparable, effective basic treatment has been established up to now. Especially patients with repeated relapses, despite all therapeutic approaches, and patients who are not able to attain an essential abstinence to alcohol, need a basic medication. It seems necessary to acknowledge that parts of them need any agonistic substance, for years, possibly lifelong. For >14 years, we have prescribed such substances with own addictive character for these patients. Methods: We present a documented best possible practice, no designed study. Since 1997, we prescribed Dihydrocodeine (DHC) to 102 heavily alcohol addicted patients, later, also Buprenorphine, Clomethiazole (>6 weeks), Baclofen, and in one case Amphetamine, each on individual indication. This paper focuses on the data with DHC, especially. The Clomethiazole-data has been submitted to a German journal. The number of treatments with the other substances is still low. Results: The 102 patients with the DHC treatment had 1367 medically assisted detoxifications and specialized therapies before! The 4 years-retention rate was 26.4%, including 2.8% successfully terminated treatments. In our 12-steps scale on clinical impression, we noticed a significant improvement from mean 3.7 to 8.4 after 2 years. The demand for medically assisted detoxifications in the 2 years remaining patients was reduced by 65.5%. Mean GGT improved from 206.6 U/l at baseline to 66.8 U/l after 2 years. Experiences with the other substances are similar but different in details. Conclusion: Similar to the Italian studies with GHB and Baclofen, we present a new approach, not only with new substances, but also with a new setting and much more trusting attitude. We observe a huge improvement, reaching an almost optimal, stable, long term status in around 1/4 of the patients already. Many further

    Alcohol use disorder (AUD) and its sequelae impose a major burden on the public health of the United States, and adequate long-term control of this disorder has not been achieved. Molecular and behavioral basic science research findings are providing the groundwork for understanding the mechanisms underlying AUD and have identified multiple candidate targets for ongoing clinical trials. However, the translation of basic research or clinical findings into improved therapeutic approaches for AUD must become more efficient. Translational research is a multistage process of streamlining the movement of basic biomedical research findings into clinical research and then to the clinical target populations. This process demands efficient bidirectional communication across basic, applied, and clinical science as well as with clinical practitioners. Ongoing work suggests rapid progress is being made with an evolving translational framework within the alcohol research field. This is helped by multiple interdisciplinary collaborative research structures that have been developed to advance translational work on AUD. Moreover, the integration of systems biology approaches with collaborative clinical studies may yield novel insights for future translational success. Finally, appreciation of genetic variation in pharmacological or behavioral treatment responses and optimal communication from bench to bedside and back may strengthen the success of translational research applications to AUD.

    Jatropha seed cake, a byproduct after biodiesel extraction, has several anti-nutrients and toxins. Solid-state fermentation was carried out for the detoxification of the Jatropha seed cake (JSC) using different fungal cultures. The reduction in the anti-nutritional components such as tannins, phytates, saponins, lectin and protease inhibitor, and phorbol esters on 6th, 9th, and 12th day of fermentation was analyzed. The phorbol ester content in the unfermented JSC was 0.83 mg/g, and the maximum degradation of phorbol esters to the extent of 75% was observed in the case of JSC fermented with Cunninghamella echinulata CJS-90. The phytate degradation in the fermented JSC was in the range of 65-96%. There was a gradual reduction of saponin content in the JSC from 6th to 12th day, and the reduction of saponin was in the range of 55-99% after solid-state fermentation. The trypsin inhibitor activity and lectin were 1,680 trypsin inhibitor units (TIU) per gram and 0.32 hemagglutinating unit in the unfermented JSC, respectively. Trypsin inhibitor activity and lectin could not be detected in JSC after 12th day of solid-state fermentation. Tannins accounted for 0.53% in unfermented JSC, and there was a marginal increase of tannins after solid-state fermentation. The results indicate that biological detoxification could be a promising method to reduce anti-nutritional compounds and toxins in the JSC. PMID:24435764

    The Aldo-Keto Reductase (AKR) superfamily comprises of several enzymes that catalyze redox transformations involved in biosynthesis, intermediary metabolism and detoxification. Substrates of the family include glucose, steroids, glycosylation end products, lipid peroxidation products, and environmental pollutants. These proteins adopt a (β/α)8 barrel structural motif interrupted by a number of extraneous loops and helixes that vary between proteins and bring structural identity to individual families. The human AKR family differs from the rodent families. Due to their broad substrate specificity, AKRs play an important role in the Phase II detoxification of a large number of pharmaceuticals, drugs, and xenobiotics. PMID:18949601

    Alcoholic hepatitis (AH) is an acute inflammatory syndrome causing significant morbidity and mortality. The prognosis is strongly dependent on disease severity, as assessed by clinical scoring systems. Reliable epidemiological data as well as knowledge of the clinical course of AH are essential for planning and resource allocation within the health care system. Likewise, individual evaluation of risk is desirable in the clinical handling of patients with AH as it can guide treatment, improve patient information, and serve as strata in clinical trials. The present PhD thesis is based on three studies using a cohort of nearly 2000 patients diagnosed with AH in Denmark from 1999 to 2008 as a cohort, in a population-based study design. The aims of this thesis were as follows. (1) To describe the incidence and short- and long-term mortality, of AH in Denmark (Study I). (2) To validate and compare the ability of the currently available prognostic scores to predict mortality in AH (Study II). (3) To investigate the short- and long-term causes of death of patients with AH (Study III). During the study decade, the annual incidence rate in the Danish population rose from 37 to 46 per 106 for men and from 24 to 34 per 106 for women. Both short- and long-term mortality rose for men and women, and the increase in short-term mortality was attributable to increasing patient age and prevalence of cirrhosis. Our evaluation of the most commonly used prognostic scores for predicting the mortality of patients with AH showed that all scores performed similarly, with Area under the Receiver Operator Characteristics curves giving values between 0.74 and 0.78 for 28-day mortality assessed on admission. Our study on causes of death showed that in the short-term (< 84 days after diagnosis), patients with AH were likely to die from liver-related events and infections. In the long-term (≥ 84 days after diagnosis), those who developed cirrhosis mainly died from liver-related causes, and

    Platinum drug delivery against the detoxification of cytoplasmic thiols is urgently required for achieving efficacy in breast cancer treatment that is over expressed by glutathione (GSH, thiol-oligopeptide). GSH-resistant polymer-cisplatin core-shell nanoparticles were custom designed based on biodegradable carboxylic functional polycaprolactone (PCL)-block-poly(ethylene glycol) diblock copolymers. The core of the nanoparticle was fixed as 100 carboxylic units and the shell part was varied using various molecular weight poly(ethylene glycol) monomethyl ethers (MW of PEGs = 100-5000 g mol-1) as initiator in the ring-opening polymerization. The complexation of cisplatin aquo species with the diblocks produced core-shell nanoparticles of 75 nm core with precise size control the particles up to 190 nm. The core-shell nanoparticles were found to be stable in saline solution and PBS and they exhibited enhanced stability with increase in the PEG shell thickness at the periphery. The hydrophobic PCL layer on the periphery of the cisplatin core behaved as a protecting layer against the cytoplasmic thiol residues (GSH and cysteine) and exhibited <5% of drug detoxification. In vitro drug-release studies revealed that the core-shell nanoparticles were ruptured upon exposure to lysosomal enzymes like esterase at the intracellular compartments. Cytotoxicity studies were performed both in normal wild-type mouse embryonic fibroblast cells (Wt-MEFs), and breast cancer (MCF-7) and cervical cancer (HeLa) cell lines. Free cisplatin and polymer drug core-shell nanoparticles showed similar cytotoxicity effects in the HeLa cells. In MCF-7 cells, the free cisplatin drug exhibited 50% cell death whereas complete cell death (100%) was accomplished by the polymer-cisplatin core-shell nanoparticles. Confocal microscopic images confirmed that the core-shell nanoparticles were taken up by the MCF-7 and HeLa cells and they were accumulated both at the cytoplasm as well at peri

    Korean pear has been used as a traditional prophylactic agent for alcohol hangover. However, its mechanism was not investigated in human yet. Therefore, we performed a randomized single blind crossover trial with 14 healthy young men to examine effects of Korean pear juice on alcohol hangover. All subjects consumed 540 ml of spirits (alcohol conc. 20.1 v/v%) after 30 min from the intervention, i.e. placebo or Korean pear juice treatment. Blood and urine specimens were collected in time-courses (9 time-points for 15 h after alcohol consumption). The total and average of hangover severity were alleviated to 16% and 21% by Korean pear juice at 15 h after the alcohol consumption, respectively (ps<0.05). Particularly, 'trouble concentrating' was significantly improved by the pear juice treatment (p<0.05). Impaired memory, and sensitivity to light and sound were significantly improved by Korean pear juice among the subjects with ALDH2*1/*1 or ALDH2*1/*2 genotypes (ps<0.05) but not in the subjects with ALDH2*2/*2 genotype. In addition, the pear juice treatment lowered levels of blood alcohol (p<0.01). Therefore, Korean pear juice may alleviate alcohol-hangover and its detoxification of alcohol seems to be modified by the genetic variation of ALDH2. PMID:23587660

    Alcohol dependence has traditionally been considered a brain disorder. Alteration in the composition of the gut microbiota has recently been shown to be present in psychiatric disorders, which suggests the possibility of gut-to-brain interactions in the development of alcohol dependence. The aim of the present study was to explore whether changes in gut permeability are linked to gut-microbiota composition and activity in alcohol-dependent subjects. We also investigated whether gut dysfunction is associated with the psychological symptoms of alcohol dependence. Finally, we tested the reversibility of the biological and behavioral parameters after a short-term detoxification program. We found that some, but not all, alcohol-dependent subjects developed gut leakiness, which was associated with higher scores of depression, anxiety, and alcohol craving after 3 wk of abstinence, which may be important psychological factors of relapse. Moreover, subjects with increased gut permeability also had altered composition and activity of the gut microbiota. These results suggest the existence of a gut–brain axis in alcohol dependence, which implicates the gut microbiota as an actor in the gut barrier and in behavioral disorders. Thus, the gut microbiota seems to be a previously unidentified target in the management of alcohol dependence. PMID:25288760

    2015-01-01

    Alcoholic liver disease (ALD) is major cause of chronic liver injury which results in liver fibrosis and cirrhosis. According to the surveillance report published by the National Institute on Alcohol Abuse and Alcoholism, liver cirrhosis is the 12th leading cause of death in the United States with 48 % of these deaths being attributed to excessive alcohol consumption. ALD includes a spectrum of disorders from simple steatosis to steatohepatitis, fibrosis, and hepatocellular carcinoma. Several mechanisms play a critical role in the pathogenesis of ALD. These include ethanol–induced oxidative stress and depletion of glutathione, pathological methionine metabolism, increased gut permeability and release of endotoxins into the portal blood, recruitment and activation of inflammatory cells including bone marrow-derived and liver resident macrophages (Kupffer cells). Chronic alcohol consumption results in liver damage and activation of hepatic stellate cells (HSCs) and myofibroblasts, leading to liver fibrosis. Here we discuss the current view on factors that are specific for different stages of ALD and those that regulate its progression, including cytokines and chemokines, alcohol-responsive intracellular signaling pathways, and transcriptional factors. We also review recent studies demonstrating that alcohol-mediated changes can be regulated on an epigenetic level, including microRNAs. Finally, we discuss the reversibility of liver fibrosis and inactivation of HSCs as a potential strategy for treating alcohol-induced liver damage. PMID:26594598

    Background Ecstasy use is prevalent among young people and often co-occurs with other drug use, but little is known about the past 12-month and lifetime psychiatric comorbidity and specific additional drug abuse among young adult ecstasy users in the general population. To provide this information, we compared current ecstasy users to former users, other illicit drug users, and non-illicit drug users. Method Data were gathered in a face-to-face survey of the United States conducted in the 2001–2002 (NESARC). Participants were household and group quarters residents aged 18–29 years (n = 8666). We measured current ecstasy use defined as any use in the past year; former ecstasy use as use prior to the past year only; other lifetime drug use included any drug other than ecstasy; lifetime non-illicit drug use as no illicit drug use. Associations were determined for nine other classes of illicit drugs, eight personality disorders, and seven mood and anxiety disorders. Results Of current ecstasy users, 44% used >3 other classes of illicit drugs in the past year, compared to 1.6% of non-ecstasy drug users. Current ecstasy use was associated with current anxiety (OR = 3.7), specifically panic disorder (OR = 7.7) and specific phobia (OR = 4.1), also alcohol abuse (OR = 21.6) and dependence (OR = 4.1) and any personality disorder (OR = 5.1) compared to non-illicit drug users. Conclusions Results indicate important differences in comorbidities of current and former ecstasy users compared to other drug users and lifetime non-illicit drug users that may affect phenotype definitions and etiologic studies. Ecstasy use may represent a distinct population of drug users for which unique treatments may be necessary. PMID:18524499

    Hazardous alcohol consumption has been frequently reported among women with HIV infection and is associated with a variety of negative health consequences. Treatments to reduce alcohol use may bring in health benefits. However, little is known regarding the utilization of alcohol treatment services among HIV+ women with hazardous drinking. Using data from the Women's Interagency HIV Study (WIHS), this study assessed utilization of any alcohol treatment in the past 6months and performed multivariable logistic regression to determine correlates of receipt of any alcohol treatment. Among 474 HIV+ women reporting recent hazardous drinking, less than one in five (19%) reported recent utilization of any alcohol treatment. Alcoholics Anonymous (AA) was the most commonly reported (12.9%), followed by inpatient detoxification (9.9%) and outpatient alcohol treatment program (7.0%). Half (51%) receiving any alcohol treatment reported utilization of multiple treatments. Multivariable analyses found alcohol treatment was more often utilized by those who had social support (odds ratio [OR]=1.68, 95% confidence interval [CI]=1.00 to 2.83), fewer economic resources (income ≤$12,000 vs. >$12,000, OR=3.10, 95% CI=1.53 to 6.27), higher levels of drinking (16-35 drinks/week vs. 12-15 drinks/week, OR=3.02, 95% CI=1.47 to 6.21; 36+ drinks/week vs. 12-15 drinks/week, OR=4.41, 95% CI=2.03 to 9.59), and those who reported any illicit drug use (OR=2.77, 95% CI=1.44 to 5.34). More efforts are needed to enhance the utilization of alcohol treatment. Our findings highlight the unique profile of those who utilized alcohol treatment. Such information is vital to improve treatment delivery to address unmet need in this particular population. PMID:26961420

    Alcohol intoxication results in marked reductions in brain glucose metabolism, which we hypothesized reflect not just its GABAergic enhancing effects but also the metabolism of acetate as an alternative brain energy source. To test this hypothesis we separately assessed the effects of alcohol intoxication on brain glucose and acetate metabolism using Positron Emission Tomography (PET). We found that alcohol intoxication significantly decreased whole brain glucose metabolism (measured with FDG) with the largest decrements in cerebellum and occipital cortex and the smallest in the thalamus. In contrast, alcohol intoxication caused a significant increase in [1-(11)C]acetate brain uptake (measured as standard uptake value, SUV), with the largest increases occurring in the cerebellum and the smallest in the thalamus. In heavy alcohol drinkers [1-(11)C]acetate brain uptake during alcohol challenge tended to be higher than in occasional drinkers (p<0.06) and the increases in [1-(11)C]acetate uptake in cerebellum with alcohol were positively associated with the reported amount of alcohol consumed (r=0.66, p<0.01). Our findings corroborate a reduction of brain glucose metabolism during intoxication and document an increase in brain acetate uptake. The opposite changes observed between regional brain metabolic decrements and regional increases in [1-(11)C]acetate uptake support the hypothesis that during alcohol intoxication the brain may rely on acetate as an alternative brain energy source and provides preliminary evidence that heavy alcohol exposures may facilitate the use of acetate as an energy substrate. These findings raise the question of the potential therapeutic benefits that increasing plasma acetate concentration (i.e. ketogenic diets) may have in alcoholics undergoing alcohol detoxification.

    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).

    AIM: To evaluate the performance of elastography by ultrasound with acoustic radiation force impulse (ARFI) in determining fibrosis stage in patients with alcoholic liver disease (ALD) undergoing alcoholic detoxification in relation to biopsy. METHODS: Eighty-three patients with ALD undergoing detoxification were prospectively enrolled. Each patient underwent ARFI imaging and a liver biopsy on the same day. Fibrosis was staged according to the METAVIR scoring system. The median of 10 valid ARFI measurements was calculated for each patient. RESULTS: Sixty-nine males and thirteen females (one patient excluded due to insufficient biopsy size) were assessed with a mean alcohol consumption of 132.4 ± 128.8 standard drinks per week and mean cumulative year duration of 17.6 ± 9.5 years. Sensitivity and specificity were respectively 82.4% (0.70-0.95) and 83.3% (0.73-0.94) (AUROC = 0.87) for F ≥ 2 with a cut-off value of 1.63m/s; 82.4% (0.64-1.00) and 78.5% (0.69-0.89) (AUROC = 0.86) for F ≥ 3 with a cut-off value of 1.84m/s; and 92.3% (0.78-1.00] and 81.6% (0.72-0.90) (AUROC = 0.89) for F = 4 with a cut-off value of 1.94 m/s. CONCLUSION: ARFI is an accurate, non-invasive and easy method for assessing liver fibrosis in patients with ALD undergoing alcoholic detoxification. PMID:27239119

    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.

    Studies of the neurobiological predisposition to consume alcohol (ethanol) and to transition to uncontrolled drinking behavior (alcoholism), as well as studies of the effects of alcohol on brain function, started a logarithmic growth phase after the repeal of the 18th Amendment to the United States Constitution. Although the early studies were primitive by current technological standards, they clearly demonstrated the effects of alcohol on brain structure and function, and by the end of the 20th century left little doubt that alcoholism is a “disease” of the brain. This review traces the history of developments in the understanding of ethanol’s effects on the most prominent inhibitory and excitatory systems of brain (GABA and glutamate neurotransmission). This neurobiological information is integrated with knowledge of ethanol’s actions on other neurotransmitter systems to produce an anatomical and functional map of ethanol’s properties. Our intent is limited in scope, but is meant to provide context and integration of the actions of ethanol on the major neurobiologic systems which produce reinforcement for alcohol consumption and changes in brain chemistry that lead to addiction. The developmental history of neurobehavioral theories of the transition from alcohol drinking to alcohol addiction is presented and juxtaposed to the neurobiological findings. Depending on one’s point of view, we may, at this point in history, know more, or less, than we think we know about the neurobiology of alcoholism. PMID:24141171

    Background: Chemical and physical pretreatment of lignocellulosic biomass improves substrate reactivity for increased microbial biofuel production, but also restricts growth via the release of furan aldehydes such as furfural and 5-hydroxymethylfurfural (5-HMF). The physiological effects of these inhibitors on thermophilic, fermentative bacteria is important to understand; especially as cellulolytic strains are being developed for consolidated bioprocessing (CBP) of lignocellulosic feedstocks. Identifying mechanisms for detoxification of aldehydes in naturally resistant strains such as Thermoanaerobacter spp. may also enable improvements in candidate CBP microorganisms. Results: T. pseudethanolicus 39E, an anaerobic, saccharolytic thermophile, was found to grow readily in the presence of 30 mM furfural and 20 mM 5-HMF and reduce these aldehydes to their respective alcohols in situ. The proteomes of T. pseudethanolicus 39E grown in the presence or absence of 15 mM furfural were compared to identify upregulated enzymes potentially responsible for the observed reduction. A total of 225 proteins were differentially regulated in response to the 15 mM furfural treatment with 152 upregulated vs. 73 downregulated. Only 86 proteins exhibited a 2-fold change in abundance in either direction. Of these, 53 were upregulated in the presence of furfural and 33 were downregulated. Two oxidoreductases were upregulated at least 2-fold by furfural and were targeted for further investigation: Teth39_1597, encodes a predicted butanol dehydrogenase (BdhA) and Teth39_1598, a predicted aldo/keto reductase (AKR). Both genes were cloned from T. pseudethanolicus 39E, with the respective enzymes overexpressed in E. coli and specific activities determined against a variety of aldehydes. BdhA showed significant activity with all aldehydes tested, including furfural and 5-HMF, using NADPH as the cofactor. AKR also showed significant activity with NADPH

    Pollinators, including honey bees, routinely encounter potentially harmful microorganisms and phytochemicals during foraging. However, the mechanisms by which honey bees manage these potential threats are poorly understood. In this study, we examine the expression of antimicrobial, immune and detoxification genes in Apis mellifera and compare between forager and nurse bees using tissue-specific RNA-seq and qPCR. Our analysis revealed extensive tissue-specific expression of antimicrobial, immune signaling, and detoxification genes. Variation in gene expression between worker stages was pronounced in the mandibular and hypopharyngeal gland (HPG), where foragers were enriched in transcripts that encode antimicrobial peptides (AMPs) and immune response. Additionally, forager HPGs and mandibular glands were enriched in transcripts encoding detoxification enzymes, including some associated with xenobiotic metabolism. Using qPCR on an independent dataset, we verified differential expression of three AMP and three P450 genes between foragers and nurses. High expression of AMP genes in nectar-processing tissues suggests that these peptides may contribute to antimicrobial properties of honey or to honey bee defense against environmentally-acquired microorganisms. Together, these results suggest that worker role and tissue-specific expression of AMPs, and immune and detoxification enzymes may contribute to defense against microorganisms and xenobiotic compounds acquired while foraging.

    Xylitol fermentation production from corncob acid hydrolysate has become an attractive and promising process. However, corncob acid hydrolysate cannot be directly used as fermentation substrate owing to various inhibitors. In this work, soaking in aqueous ammonia (SAA) pretreatment was employed to reduce the inhibitors in acid hydrolysate. After detoxification, the corncob acid hydrolysate was fermented by immobilized Candida tropicalis cell to produce xylitol. Results revealed that SAA pretreatment showed high delignification and efficient removal of acetyl group compounds without effect on cellulose and xylan content. Acetic acid was completely removed, and the content of phenolic compounds was reduced by 80%. Furthermore, kinetic behaviors of xylitol production by immobilized C. tropicalis cell were elucidated from corncob acid hydrolysate detoxified with SAA pretreatment and two-step adsorption method, respectively. The immobilized C. tropicalis cell showed higher productivity efficiency using the corncob acid hydrolysate as fermentation substrate after detoxification with SAA pretreatment than by two-step adsorption method in the five successive batch fermentation rounds. After the fifth round fermentation, about 60 g xylitol/L fermentation substrate was obtained for SAA pretreatment detoxification, while about 30 g xylitol/L fermentation substrate was obtained for two-step adsorption detoxification.

    Anopheles sinensis is an important malaria vector in China and other Southeast Asian countries, and the emergence of insecticide resistance in this mosquito poses a serious threat to the efficacy of malaria control programs. The recently published An. sinensis genome and transcriptome provide an opportunity to understand the molecular mechanisms of insecticide resistance. Analysis of the An. sinensis genome revealed 174 detoxification genes, including 93 cytochrome P450s (P450s), 31 glutathione-S-transferases (GSTs), and 50 choline/carboxylesterases (CCEs). The gene number was similar to that in An. gambiae, but represented a decrease of 29% and 42% compared with Aedes aegypti and Culex quinquefasciatus, respectively. The considerable contraction in gene number in Anopheles mosquitoes mainly occurred in two detoxification supergene families, P450s and CCEs. The available An. sinensis transcriptome was also re-analyzed to further identify key resistance-associated detoxification genes. Among 174 detoxification genes, 124 (71%) were detected. Several candidate genes overexpressed in a deltamethrin-resistant strain (DR-strain) were identified as belonging to the CYP4 or CYP6 family of P450s and the Delta GST class. These generated data provide a basis for identifying the resistance-associated genes of An. sinensis at the molecular level. PMID:26588704

    On May 14, 2013, the National Transportation Safety Board (NTSB) recommended lowering the legal blood-alcohol limit to 0.05 g/dL for motor vehicle operators in the United States, in an effort to reduce the risk of injuries and deaths caused by a driver's alcohol impairment (NTSB/SR-13/01). This recommendation has prompted other organizations and agencies, including the National Safety Council, to evaluate and consider supporting this action. In order to determine the scientific and legal feasibility and advisability of lowering or establishing 0.05 per se laws, we examined 554 alcohol-related publications. Risk factors, instrument reliability, law enforcement, and adjudication issues were considered in this overview of the literature. The extensive scientific literature reviewed provides ample support for lowering the operation of motor vehicle alcohol limits to 0.05, and for supporting the NTSB recommendations. Research clearly demonstrates that impairment begins at very low concentrations, well below the recommended NTSB limit, and increases with concentration. Lowering the limit to 0.05 will save many lives and prevent injuries. Breath, blood, and saliva samples have proved to be accurate and reliable specimens for legal acceptability in a court of law.

  15. Alcohol advertising and alcohol consumption by adolescents.

    PubMed

    Saffer, Henry; Dave, Dhaval

    2006-06-01

    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. PMID:16475245

    Okazaki, N; Higuchi, S

    1995-02-01

    This paper presents an analysis of alcohol beverage advertisements appearing in weekly magazines and comics. Few studies have be undertaken on this sector of the mass media in Japan. The results are compared with those of a similar study in the United States. We also review alcohol advertisements on television and the drinking scenes shown in comics. On the average, Japanese magazines tend to contain fewer alcohol advertisements than American magazines. However, 18 (53%) in 34 weekly magazines contained alcohol advertisements showing that such magazines are an important medium for alcoholic beverage advertising in Japan. There were also alcohol advertisements targeting to particular populations, youths and women, which may be connected with the increase in drinking in these groups. Alcohol advertisements in the mass media should be monitored continuously as public health issue. PMID:7726756

    PubMed

    Hensel, M; Volk, T; Kox, W J

    1999-05-01

    Treatment of opioid addicts by means of competitive opioid receptor antagonists was developed at the University of Vienna in 1987 by Loimer and co-workers. They compared two withdrawal regimens: The short Opiate withdrawal using a staggered naloxone regimen and the rapid opiate detoxification during general anesthesia by means of high doses of naloxone. Based on the latter concept, various modifications have been developed world-wide using either naloxone or as an alternative, naltrexone, an antagonist available for oral administration only. However, there are considerable objections to opioid detoxification during general anasthesia. The main criticism is based an the supposedly unacceptable high risk:benefit-ratio, the higher costs, the lack of psycho-social support, and the lack of prospective studies. However, first results suggest that rapid detoxification procedures are more successful in decreasing relapse than methods which are based on psychiatric treatment alone. As sympathetic hyperfunction is common in rapid detoxification procedures using high doses of opioid receptor antagonists, it is essential to avoid severe autonomic imbalance with possible subsequent impairment of organ functions. To prevent those disturbances, general anesthesia plays an important role. So far, there is almost no information about such methods in the anesthesiological literature. In this article the clinical relevance of such methods is discussed summarizing both the available literature and our own experience and we conclude that rapid opioid detoxification under general anesthesia is a safe and efficient method to suppress withdrawal symptoms. This treatment may be of benefit in patients who particularly suffer from severe withdrawal symptoms and who have failed repeatedly to complete conventional withdrawal. PMID:10372215

  20. Determination of detoxification to Daphnia magna of four pharmaceuticals and seven surfactants by activated sludge.

    PubMed

    Dave, Göran; Herger, Gabriella

    2012-07-01

    Pharmaceuticals are bioactive compounds generally resistant to biodegradation, which can make them problematic when they are released into nature. The use pattern for pharmaceuticals means that they are discharged into water via sewage treatment plants. Also surfactants are discharged through sewage treatment plants, primarily due to their use in detergents and shampoos and other cleaners. In this study the acute toxicity to Daphnia magna of four pharmaceuticals (ciprofloxacin, ibuprofen, paracetamol and zinc pyrithione) and seven surfactants (C8 alkyl glucoside, C6 alkyl glucoside, sodium caprylimidiopropionate, tallow-trimethyl-ammonium chloride, potassium decylphosphate, propylheptanol ethoxylate and alkylmonoethanolamide ethoxylate) was determined. Abiotic (without activated sludge bacteria) and biotic (with activated sludge bacteria) detoxification was also determined. The 24-h EC50s ranged from 2 μg L(-1) for the most toxic substance (zinc pyrithione) to 2 g L(-1) for the least toxic compound (C6 alkyl glucoside). Detoxification rates determined as the ratio between initial EC50 and EC50 after 1 week in water with activated sludge bacteria ranged from 0.4 (paracetamol) to 13 (zinc pyrithione). For most of these chemicals detoxification rate decreased after 1 week, but for one (alkylmonoethanolamide ethoxylate) it increased from about 2 to 30 times after 2 weeks. Many of these chemicals were "detoxified" also abiotically at about the same rate as biotically. Further studies are needed to determine the degradation products that were precipitated (aggregated) for some of the tested chemicals. Altogether, this study has shown that there are large differences in toxicity among chemicals entering sewage treatment plants, but also that the detoxification of them can differ. Therefore, the detoxification should receive more attention in the hazard and risk assessment of chemicals entering sewage treatment plants. PMID:22480943

  12. Alcohol outlets and clusters of violence

    PubMed Central

    2011-01-01

    Background Alcohol related violence continues to be a major public health problem in the United States. In particular, there is substantial evidence of an association between alcohol outlets and assault. However, because the specific geographic relationships between alcohol outlets and the distribution of violence remains obscured, it is important to identify the spatial linkages that may exist, enhancing public health efforts to curb both violence and morbidity. Methods The present study utilizes police-recorded data on simple and aggravated assaults in Cincinnati, Ohio. Addresses of alcohol outlets for Cincinnati, including all bars, alcohol-serving restaurants, and off-premise liquor and convenience stores were obtained from the Ohio Division of Liquor Control and geocoded for analysis. A combination of proximity analysis, spatial cluster detection approaches and a geographic information system were used to identify clusters of alcohol outlets and the distribution of violence around them. Results A brief review of the empirical work relating to alcohol outlet density and violence is provided, noting that the majority of this literature is cross-sectional and ecological in nature, yielding a somewhat haphazard and aggregate view of how outlet type(s) and neighborhood characteristics like social organization and land use are related to assaultive violence. The results of the statistical analysis for Cincinnati suggest that while alcohol outlets are not problematic per se, assaultive violence has a propensity to cluster around agglomerations of alcohol outlets. This spatial relationship varies by distance and is also related to the characteristics of the alcohol outlet agglomeration. Specifically, spatially dense distributions of outlets appear to be more prone to clusters of assaultive violence when compared to agglomerations with a lower density of outlets. Conclusion With a more thorough understanding of the spatial relationships between alcohol outlets and the

    Efficient microbial conversion of lignocellulosic hydrolysates to biofuels is a key barrier to the economically viable deployment of lignocellulosic biofuels. A chief contributor to this barrier is the impact on microbial processes and energy metabolism of lignocellulose-derived inhibitors, including phenolic carboxylates, phenolic amides (for ammonia-pretreated biomass), phenolic aldehydes, and furfurals. To understand the bacterial pathways induced by inhibitors present in ammonia-pretreated biomass hydrolysates, which are less well studied than acid-pretreated biomass hydrolysates, we developed and exploited synthetic mimics of ammonia-pretreated corn stover hydrolysate (ACSH). To determine regulatory responses to the inhibitors normally present in ACSH, we measured transcript and protein levels in an Escherichia coli ethanologen using RNA-seq and quantitative proteomics during fermentation to ethanol of synthetic hydrolysates containing or lacking the inhibitors. Our study identified four major regulators mediating these responses, the MarA/SoxS/Rob network, AaeR, FrmR, and YqhC. Induction of these regulons was correlated with a reduced rate of ethanol production, buildup of pyruvate, depletion of ATP and NAD(P)H, and an inhibition of xylose conversion. The aromatic aldehyde inhibitor 5-hydroxymethylfurfural appeared to be reduced to its alcohol form by the ethanologen during fermentation, whereas phenolic acid and amide inhibitors were not metabolized. Together, our findings establish that the major regulatory responses to lignocellulose-derived inhibitors are mediated by transcriptional rather than translational regulators, suggest that energy consumed for inhibitor efflux and detoxification may limit biofuel production, and identify a network of regulators for future synthetic biology efforts.

    1998-11-01

    The American Indian and Alaska Native population is a culturally diverse population with a current census of 1,959,000. Prior to White contact, there was historically little use of alcoholic beverages except for American Indians in the Southwest. After White contact, use and misuse of alcohol escalated rapidly; however, the prevalence, patterns, and problems of drinking alcoholic beverages vary enormously even in tribes closely linked geographically. American Indians and Alaska Natives have preserved and revitalized a number of traditional healing practices and applied these to the treatment of alcohol-related problems. These healing practices include the following: nativistic movements, sacred dances, sweat lodges, talking circle, four circles, and cultural enhancement programs. Additionally, Western treatment approaches have been applied in the treatment of problems related to alcohol, such as medication for detoxification, disulfiram (Antabuse), Alcoholics Anonymous, and behavioral interventions. Several investigators have completed a small number of naturalistic follow-up studies, but no one has undertaken a randomized controlled trial looking at specific methods of alcohol treatment in American Indians or Alaska Natives. American Indian and Alaska Native communities have adapted and integrated both Traditional and Western approaches to fit their own unique sociocultural needs. PMID:9818991

    Alcoholism is becoming one of the most serious issues in Korea. The purpose of this review article was to understand the present status of the treatment system for alcoholism in Korea compared to the United States and to suggest its developmental direction in Korea. Current modalities of alcoholism treatment in Korea including withdrawal treatment, pharmacotherapy, and psychosocial treatment are available according to Korean evidence-based treatment guidelines. Benzodiazepines and supportive care including vitamin and nutritional support are mainly used to treat alcohol withdrawal in Korea. Naltrexone and acamprosate are the drugs of first choice to treat chronic alcoholism. Psychosocial treatment methods such as individual psychotherapy, group psychotherapy, family therapy, cognitive behavior therapy, cue exposure therapy, 12-step facilitation therapy, self-help group therapy, and community-based treatment have been carried out to treat chronic alcoholism in Korea. However, current alcohol treatment system in Korea is not integrative compared to that in the United States. To establish the treatment system, it is important to set up an independent governmental administration on alcohol abuse, to secure experts on alcoholism, and to conduct outpatient alcoholism treatment programs and facilities in an open system including some form of continuing care.

    2014-01-01

    Abstract Alcohol is a severe hepatotoxicant that causes liver abnormalities such as steatosis, cirrhosis, and hepatocarcinoma. Crepidiastrum denticulatum (CD) is a well-known, traditionally consumed vegetable in Korea, which was recently reported to have bioactive compounds with detoxification and antioxidant properties. In this study, we report the hepatoprotective effect of CD extract against chronic alcohol-induced liver damage in vivo. The rats that were given CD extract exhibited decreased alanine aminotransferase, aspartate aminotransferase, and γ-glutamyl transpeptidase activities, which are liver damage markers that are typically elevated by alcohol consumption. The results were confirmed by histopathology with hematoxylin and eosin staining. Chronic alcohol consumption induced the formation of alcoholic fatty liver. However, treatment with CD extract dramatically decreased the hepatic lipid droplets. Treatment with CD extract also restored the antioxidative capacity and lipid peroxidation of the liver that had been changed by alcohol consumption. Furthermore, treatment with CD extract normalized the activities of the antioxidative enzymes superoxide dismutase, catalase, glutathione reductase, and glutathione peroxidase, which had been decreased by alcohol consumption. The results indicate that CD extract has protective effects against chronic alcohol hepatotoxicity in rats by increasing the liver's antioxidant capacity, and has potential as a dietary supplement intervention for patients with alcohol-induced liver damage.

    Platinum drug delivery against the detoxification of cytoplasmic thiols is urgently required for achieving efficacy in breast cancer treatment that is over expressed by glutathione (GSH, thiol-oligopeptide). GSH-resistant polymer-cisplatin core-shell nanoparticles were custom designed based on biodegradable carboxylic functional polycaprolactone (PCL)-block-poly(ethylene glycol) diblock copolymers. The core of the nanoparticle was fixed as 100 carboxylic units and the shell part was varied using various molecular weight poly(ethylene glycol) monomethyl ethers (MW of PEGs = 100-5000 g mol-1) as initiator in the ring-opening polymerization. The complexation of cisplatin aquo species with the diblocks produced core-shell nanoparticles of 75 nm core with precise size control the particles up to 190 nm. The core-shell nanoparticles were found to be stable in saline solution and PBS and they exhibited enhanced stability with increase in the PEG shell thickness at the periphery. The hydrophobic PCL layer on the periphery of the cisplatin core behaved as a protecting layer against the cytoplasmic thiol residues (GSH and cysteine) and exhibited <5% of drug detoxification. In vitro drug-release studies revealed that the core-shell nanoparticles were ruptured upon exposure to lysosomal enzymes like esterase at the intracellular compartments. Cytotoxicity studies were performed both in normal wild-type mouse embryonic fibroblast cells (Wt-MEFs), and breast cancer (MCF-7) and cervical cancer (HeLa) cell lines. Free cisplatin and polymer drug core-shell nanoparticles showed similar cytotoxicity effects in the HeLa cells. In MCF-7 cells, the free cisplatin drug exhibited 50% cell death whereas complete cell death (100%) was accomplished by the polymer-cisplatin core-shell nanoparticles. Confocal microscopic images confirmed that the core-shell nanoparticles were taken up by the MCF-7 and HeLa cells and they were accumulated both at the cytoplasm as well at peri

    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

  3. Alcohol's effect on lactation.

    PubMed

    Mennella, J

    2001-01-01

    Although pregnant women are discouraged from drinking alcohol because of alcohol's detrimental effect on fetal development, the lore of many cultures encourages lactating women to drink alcohol to optimize breast milk production and infant nutrition. In contrast to this folklore, however, studies demonstrate that maternal alcohol consumption may slightly reduce milk production. Furthermore, some of the alcohol consumed by a lactating woman is transferred to her milk and thus consumed by the infant. This alcohol consumption may adversely affect the infant's sleep and gross motor development and influence early learning about alcohol. Based on this science, it would seem that the recommendation for a nursing mother to drink a glass of beer or wine shortly before nursing may actually be counterproductive. PMID:11810962

    This paper is based upon the "Charles Lieber Satellite Symposia" organized by Manuela G. Neuman at the Research Society on Alcoholism (RSA) Annual Meetings, 2013 and 2014. The present review includes pre-clinical, translational and clinical research that characterize alcoholic liver disease (ALD) and non-alcoholic steatohepatitis (NASH).

    Alcohol dependence represents a chronic and relapsing disease affecting nearly 10% of the general population both in the United States and in Europe, with a widespread burden of morbidity and mortality. Alcohol dependence represents the most common cause of liver damage in the Western Countries. Although alcoholic liver disease is associated primarily with heavy drinking, continued alcohol consumption, even in low doses after the onset of liver disease, increases the risk of severe consequences, including mortality. Consequently the ideal treatment of patients affected by alcohol dependence and alcoholic liver disease should aim at achieving long-term total alcohol abstinence and preventing relapse. The aim of the present review is to provide an update on the management of alcohol dependence in patients with alcoholic liver disease. Increasing evidences suggests the usefulness of psychosocial interventions and medications combined in order to reduce alcohol intake, promote abstinence and prevent relapse in alcohol dependent patients. Disulfiram, naltrexone and acamprosate have been approved for this indication; gamma-hydroxybutyric acid (GHB) is approved in Italy and Austria. However, these drugs have not been tested in patients with advanced liver disease. Amongst other emerging pharmacotherapies for alcoholism, topiramate, ondansetron, and baclofen seem the most promising ones. Both topiramate and ondansetron hold a safe profile in alcoholic patients; however, none of them has been tested in alcoholic patients with advanced liver disease. To date, baclofen represents the only anti-craving medication formally tested in a randomized clinical trial in alcoholic patients affected by liver cirrhosis, although additional confirmatory studies are warranted.

    Alcohol consumption is common across subpopulations in the United States. However, the health burden associated with alcohol consumption varies across groups, including those defined by demographic characteristics such as age, race/ ethnicity, and gender. Large national surveys, such as the National Epidemiologic Survey on Alcohol and Related Conditions and the National Survey on Drug Use and Health, found that young adults ages 18-25 were at particularly high risk of alcohol use disorder and unintentional injury caused by drinking. These surveys furthermore identified significant variability in alcohol consumption and its consequences among racial/ethnic groups. White respondents reported the highest prevalence of current alcohol consumption, whereas alcohol abuse and dependence were most prevalent among Native Americans. Native Americans and Blacks also were most vulnerable to alcohol-related health consequences. Even within ethnic groups, there was variability between and among different subpopulations. With respect to gender, men reported more alcohol consumption and binge drinking than women, especially in older cohorts. Men also were at greater risk of alcohol abuse and dependence, liver cirrhosis, homicide after alcohol consumption, and drinking and driving. Systematic identification and measurement of the variability across demographics will guide prevention and intervention efforts, as well as future research. PMID:27159807

    Although past research has identified psychological and behavioral consequences for adults who were abused as children, few studies have examined the incidence and consequences of childhood physical abuse among adult alcoholics. The purpose of this study was to assess the prevalence of a childhood history of physical abuse in adult male alcoholics and to determine what differences may exist in the psychological profile and patterns of alcohol abuse in abused and nonabused alcoholics. The study sample was comprised of 100 male alcoholic inpatients from the alcoholism treatment unit at a metropolitan Veterans Administration hospital. Subjects were administered a self-report devised by the authors to assess a history of childhood physical abuse, the Michigan Alcoholism Screening Test (MAST), the Severity of Alcohol Dependence Questionnaire (SADQ), and the Symptom Checklist-90-Revised (SCL-90-R). Findings indicated that approximately one-third of the alcoholics were physically abused as children. Abused alcoholics reported having more severe psychological symptoms and distress than their nonabused counterparts, although they did not differ on the onset, severity, or treatment history for alcohol dependency.

    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

    This study examines the effect of state excise taxes on different types of alcoholic beverages (spirits, wine, and beer) on alcohol-attributable injury mortalities--deaths caused by motor vehicle accidents, suicides, homicides, and falls--in the United States between 1995 and 2004, using state-level panel data. There is evidence that injury deaths attributable to alcohol respond differently to changes in state excise taxes on alcohol-specific beverages. This study examines the direct relationship between injury deaths and excise taxes without testing the degree of the association between excise taxes and alcohol consumption. The study finds that beer taxes are negatively related to motor vehicle accident mortality, while wine taxes are negatively associated with suicides and falls. The positive coefficient of the spirit taxes on falls implies a substitution effect between spirits and wine, suggesting that an increase in spirit tax will cause spirit buyers to purchase more wine. This study finds no evidence of a relationship between homicides and state excise taxes on alcohol. Thus, the study concludes that injury deaths attributable to alcohol respond differently to the excise taxes on different types of alcoholic beverages. PMID:20306111

    Context Excessive alcohol consumption is the nation’s third leading cause of preventable deaths. If untreated, 6% of alcohol-dependent patients experience alcohol withdrawal, with up to 10% of those experiencing delirium tremens (DT), when they stop drinking. Without routine screening, patients often experience DT without warning. Objective: Reduce the incidence of alcohol withdrawal advancing to DT, restraint use, and transfers to the intensive care unit (ICU) in patients with DT. Design: In October 2009, the alcohol withdrawal team instituted a care management guideline used by all disciplines, which included tools for screening, assessment, and symptom management. Data were obtained from existing datasets for three quarters before and four quarters after implementation. Follow-up data were analyzed and showed a great deal of variability in transfers to the ICU and restraint use. Percentage of patients who developed DT showed a downward trend. Main Outcome Measures: Incidence of alcohol withdrawal advancing to DT and, in patients with DT, restraint use and transfers to the ICU. Results: Initial data revealed a decrease in percentage of patients with alcohol withdrawal who experienced DT (16.4%–12.9%). In patients with DT, restraint use decreased (60.4%–44.4%) and transfers to the ICU decreased (21.6%–15%). Follow-up data indicated a continued downward trend in patients with DT. Changes were not statistically significant. Restraint use and ICU transfers maintained postimplementation levels initially but returned to preimplementation levels by third quarter 2012. Conclusion: Early identification of patients for potential alcohol withdrawal followed by a standardized treatment protocol using symptom-triggered dosing improved alcohol withdrawal management and outcomes.

    Recently South Korean society has experienced an increase in alcohol use related problems, as well as alcohol use among women. The purpose of this paper is to describe the cultural context of and to summarize the current state of knowledge of women's drinking in South Korea. Subscribing to Confucian principles, traditional Korean society has allowed drinking for men, but not for women. However, as society has changed, contemporary women drink at a younger age and consume larger amounts of alcohol than their prior generations. The current trends suggest an urgent need for research on the etiology and trajectory of women's alcohol use among various populations and the need to develop intervention programs tailored to the specific needs of women.

    Alcoholism is a debilitating disorder for the individual and very costly for society. A major goal of alcohol research is to understand the neural underpinnings associated with the transition from alcohol use to alcohol dependence. Positive reinforcement is important in the early stages of alcohol use and abuse. Negative reinforcement can be important early in alcohol use by people self-medicating coexisting affective disorders, but its role likely increases following the transition to dependence. Chronic exposure to alcohol induces changes in neural circuits that control motivational processes, including arousal, reward, and stress. These changes affect systems utilizing the signaling molecules dopamine, opioid peptides, γ-aminobutyric acid, glutamate, and serotonin, as well as systems modulating the brain’s stress response. These neuroadaptations produce changes in sensitivity to alcohol’s effects following repeated exposure (i.e., sensitization and tolerance) and a withdrawal state following discontinuation of alcohol use. Chronic alcohol exposure also results in persistent neural deficits, some of which may fully recover following extended periods of abstinence. However, the organism remains susceptible to relapse, even after long periods of abstinence. Recent research focusing on brain arousal, reward, and stress systems is accelerating our understanding of the components of alcohol dependence and contributing to the development of new treatment strategies.

    The high levels of alcohol consumption characteristic of adolescence may be in part biologically based, given that elevated consumption levels are also evident during this developmental transition in other mammalian species as well. Studies conducted using a simple animal model of adolescence in the rat has shown adolescents to be more sensitive than adults to social facilitatory and rewarding effects of alcohol, but less sensitive to numerous alcohol effects that may serve as cues to limit intake. These age-specific alcohol sensitivities appear related to differential rates of development of neural systems underlying different alcohol effects as well as to an ontogenetic decline in rapid brain compensations to alcohol, termed “acute tolerance”. In contrast, these adolescent-typical sensitivities to alcohol do not appear to be notably influenced by pubertally-related increases in gonadal hormones. Although data are sparse, there are hints that similar alcohol sensitivities may also be seen in human adolescents, with this developmentally decreased sensitivity to alcohol’s intoxicating effects possibly exacerbated by genetic vulnerabilities also characterized by an insensitivity to alcohol intoxication, thereby perhaps permitting especially high levels of alcohol consumption among vulnerable youth.

    It has been well documented that long-term abuse of alcohol leads to dysfunction of multiple organ systems of the body. The liver, which is the primary organ responsible for alcohol metabolism, is also a major target for damage. Cirrhosis of the liver is the seventh leading cause of death in the United States. The radiologist plays an important role in the evaluation and possibly in the treatment of the conditions which result from alcohol abuse. The advantages and limitations of various radiologic diagnostic modalities in the evaluation of alcoholic liver disease are presented and discussed. 47 references.

    Despite the generally held view that alcohol is an unspecific pharmacological agent, recent molecular pharmacology studies demonstrated that alcohol has only a few known primary targets. These are the NMDA, GABA(A), glycine, 5-hydroxytryptamine 3 (serotonin) and nicotinic ACh receptors as well as L-type Ca(2+) channels and G-protein-activated inwardly rectifying K(+) channels. Following this first hit of alcohol on specific targets in the brain, a second wave of indirect effects on a variety of neurotransmitter/neuropeptide systems is initiated that leads subsequently to the typical acute behavioural effects of alcohol, ranging from disinhibition to sedation and even hypnosis, with increasing concentrations of alcohol. Besides these acute pharmacodynamic aspects of alcohol, we discuss the neurochemical substrates that are involved in the initiation and maintenance phase of an alcohol drinking behaviour. Finally, addictive behaviour towards alcohol as measured by alcohol-seeking and relapse behaviour is reviewed in the context of specific neurotransmitter/neuropeptide systems and their signalling pathways. The activity of the mesolimbic dopaminergic system plays a crucial role during the initiation phase of alcohol consumption. Following long-term, chronic alcohol consumption virtually all brain neurotransmission seems to be affected, making it difficult to define which of the systems contributes the most to the transition from controlled to compulsive alcohol use. However, compulsive alcohol drinking is characterized by a decrease in the function of the reward neurocircuitry and a recruitment of antireward/stress mechanisms comes into place, with a hypertrophic corticotropin-releasing factor system and a hyperfunctional glutamatergic system being the most important ones.

    Research into human biotransformation and elimination systems continues to evolve. Various clinical and in vivo studies have been undertaken to evaluate the effects of foods and food-derived components on the activity of detoxification pathways, including phase I cytochrome P450 enzymes, phase II conjugation enzymes, Nrf2 signaling, and metallothionein. This review summarizes the research in this area to date, highlighting the potential for foods and nutrients to support and/or modulate detoxification functions. Clinical applications to alter detoxification pathway activity and improve patient outcomes are considered, drawing on the growing understanding of the relationship between detoxification functions and different disease states, genetic polymorphisms, and drug-nutrient interactions. Some caution is recommended, however, due to the limitations of current research as well as indications that many nutrients exert biphasic, dose-dependent effects and that genetic polymorphisms may alter outcomes. A whole-foods approach may, therefore, be prudent. PMID:26167297
