The aim of the present study was to clarify the association between child abuse experiences and drug addiction severity among Japanese drug-dependent patients using the Addiction Severity Index-Japanese version (ASI-J). One hundred and eleven inpatients and outpatients with drug dependence participated in the study. Some of the questions on the ASI-J asked about lifetime experiences of abuse. A higher percentage of female participants experienced child abuse compared with male participants. Male participants who experienced child abuse (MEA) had a significantly higher severity of drug use than men who did not experience it (MNEA). Female participants who experienced child abuse (FEA) had significantly more serious problems in family/social relationships than female participants who did not experience it (FNEA). Patients in the MEA group were arrested less frequently for drug charges, experienced more serious problems with their fathers, and experienced more severe anxiety in their lifetime compared with the MNEA group. The FEA group experienced more serious troubles with their sexual partners, close friends, and families and experienced more severe psychiatric problems in their lifetime compared with the FNEA group. These results suggest gender differences in the problems experienced by drug-dependent patients with child abuse experiences, and gender-specific interventions may be more effective in treating their drug dependence.

We examined whether alcohol-dependent individuals with sustained substance use or psychiatric problems after completing treatment were more likely to experience low social status and whether continued help-seeking would improve outcomes. Ongoing alcohol, drug and psychiatric problems after completing treatment were associated with increased odds of low social status (unemployment, unstable housing and/or living in high-poverty neighborhood) over 7 years. The impact of drug problems declined over time, and there were small, delayed benefits of AA attendance on social status. Alcohol-dependent individuals sampled from public and private treatment programs (N = 491; 62% male) in Northern California were interviewed at treatment entry and 1, 3, 5 and 7 years later. Random effects models tested relationships between problem severity (alcohol, drug and psychiatric problems) and help-seeking (attending specialty alcohol/drug treatment and Alcoholics Anonymous, AA) with low social status (unemployment, unstable housing and/or living in a high-poverty neighborhood) over time. The proportion of participants experiencing none of the indicators of low social status increased between baseline and the 1-year follow-up and remained stable thereafter. Higher alcohol problem scores and having any drug and/or psychiatric problems in the years after treatment were associated with increased odds of low social status over time. An interaction of drug problems with time indicated the impact of drug problems on social status declined over the 7-year period. Both treatment-seeking and AA attendance were associated with increased odds of low social status, although lagged models suggested there were small, delayed benefits of AA attendance on improved social status over time. Specialty addiction treatment alone was not sufficient to have positive long-term impacts on social status and social integration of most alcohol-dependent people.

Multiple forms of drug abuse/dependence frequently co-occur with problem/pathological gambling (PPG). The current study examines the extent to which genetic and environmental factors contribute to their co-occurrence. Bivariate models investigated the magnitude and correlation of genetic and environmental contributions to problem/pathological gambling and its co-occurrence with nicotine dependence, cannabis abuse/dependence and stimulant abuse/dependence. Computer-assisted telephone interviews in the community. Participants were 7869 male twins in the Vietnam Era Twin Registry, a USA-based national twin registry. Life-time DSM-III-R diagnoses for problem/pathological gambling, nicotine dependence, cannabis abuse/dependence and stimulant abuse/dependence were determined using the Diagnostic Interview Schedule. All drug-use disorders displayed additive genetic and non-shared environmental contributions, with cannabis abuse/dependence also displaying shared environmental contributions. Both genetic [genetic correlation rA = 0.22; 95% confidence interval (CI) = 0.10-0.34] and non-shared environmental components (environmental correlation rE = 0.24; 95% CI = 0.10-0.37) contributed to the co-occurrence of problem/pathological gambling and nicotine dependence. This pattern was shared by cannabis abuse/dependence (rA = 0.32; 95% CI = 0.05-1.0; rE = 0.36; 95% CI = 0.16-0.55) but not stimulant abuse/dependence (SAD), which showed only genetic contributions to the co-occurrence with problem/pathological gambling (rA = 0.58; 95% CI = 0.45-0.73). Strong links between gambling and stimulant-use disorders may relate to the neurochemical properties of stimulants or the illicit nature of using 'hard' drugs such as cocaine. The greater contribution of environmental factors to the co-occurrence between problem/pathological gambling and 'softer' forms of drug abuse/dependence (cannabis, tobacco) suggest that environmental interventions (perhaps relating to availability and legality) may help to diminish the relationship between problem/pathological gambling and tobacco- and cannabis-use disorders. © 2013 Society for the Study of Addiction.

This study examined whether the experiences of childhood or adolescent parental divorce/separation and parental alcohol problems affected the likelihood of offspring DSM-IV lifetime alcohol dependence, controlling for parental history of drug, depression, and antisocial behavior problems. Data were drawn from the 2001-2002 National Epidemiological Survey on Alcohol and Related Conditions (NESARC), a nationally representative United States survey of 43,093 civilian non-institutionalized participants aged 18 and older, interviewed in person. Logistic regression models were used to calculate the main and interaction effects of childhood or adolescent parental divorce/separation and parental history of alcohol problems on offspring lifetime alcohol dependence, after adjusting for parental history of drug, depression, and antisocial behavior problems. Childhood or adolescent parental divorce/separation and parental history of alcohol problems were significantly related to offspring lifetime alcohol dependence, after adjusting for parental history of drug, depression, and antisocial behavior problems. Experiencing parental divorce/separation during childhood, even in the absence of parental history of alcohol problems, remained a significant predictor of lifetime alcohol dependence. Experiencing both childhood or adolescent parental divorce/separation and parental alcohol problems had a significantly stronger impact on the risk for DSM-IV alcohol dependence than the risk incurred by either parental risk factor alone. Further research is needed to better identify the factors that increase the risk for lifetime alcohol dependence among those who experience childhood or adolescent parental divorce/separation.

Few studies have examined how changes in psychiatric symptoms over time are associated with changes in drug use and severity of drug problems. No studies have examined these relationships among methamphetamine (MA)-dependent persons receiving motivational interviewing within the context of standard outpatient treatment. Two hundred seventeen individuals with MA dependence were randomly assigned to a standard single session of motivational interviewing (MI) or an intensive 9-session model of MI. Both groups received standard outpatient group treatment. The Addiction Severity Index (ASI) and timeline follow-back (TLFB) for MA use were administered at treatment entry and 2-, 4-, and 6-month follow-ups. Changes in ASI psychiatric severity between baseline and 2 months predicted changes in ASI drug severity during the same time period, but not changes on measures of MA use. Item analysis of the ASI drug scale showed that psychiatric severity predicted how troubled or bothered participants were by their drug us, how important they felt it was for them to get treatment, and the number of days they experienced drug problems. However, it did not predict the number days they used drugs in the past 30 days. These associations did not differ between study conditions, and they persisted when psychiatric severity and outcomes were compared across 4- and 6-month time periods. Results are among the first to track how changes in psychiatric severity over time are associated with changes in MA use and severity of drug problems. Treatment efforts targeting reduction of psychiatric symptoms among MA-dependent persons might be helpful in reducing the level of distress and problems associated with MA use but not how often it is used. There is a need for additional research describing the circumstances under which the experiences and perceptions of drug-related problems diverge from frequency of consumption.
Clinical relevance of cannabis tolerance and dependence.
Jones, R T; Benowitz, N L; Herning, R I
1981-01-01
Psychoactive drugs are often widely used before tolerance and dependence is fully appreciated. Tolerance to cannabis-induced cardiovascular and autonomic changes, decreased intraocular pressure, sleep and sleep EEG, mood and behavioral changes is acquired and, to a great degree, lost rapidly with optimal conditions. Mechanisms appear more functional than metabolic. Acquisition rate depends on dose and dose schedule. Dependence, manifested by withdrawal symptoms after as little as 7 days of THC administration, is characterized by irritability, restlessness, insomnia, anorexia, nausea, sweating, salivation, increased body temperature, altered sleep and waking EEG, tremor, and weight loss. Mild and transient in the 120 subjects studied, the syndrome was similar to sedative drug withdrawal. Tolerance to drug side effects can be useful. Tolerance to therapeutic effects or target symptoms poses problems. Clinical significance of dependence is difficult to assess since drug-seeking behavior has many determinants. Cannabis-induced super sensitivity should be considered wherever chronic drug administration is anticipated in conditions like epilepsy, glaucoma or chronic pain. Cannabis pharmacology suggests ways of minimizing tolerance and dependence problems.
Are clinical impressions of adolescent substance use accurate?
Wilson, Celeste R; Sherritt, Lon; Gates, Erin; Knight, John R

To compare providers' impressions of adolescents' level of substance use with diagnostic classifications from a structured diagnostic interview. Secondary analysis of data was conducted from a validation study of the CRAFFT substance abuse screening test of 14- to 18-year-old medical clinic patients (n = 533) and their corresponding medical care providers (n = 109) at an adolescent clinic affiliated with a large tertiary care pediatric hospital. Medical care providers completed a form that recorded their clinical impressions of patients' level of alcohol and drug involvement (none, minimal, problem, abuse, dependence) and demographic characteristics. The form included brief diagnostic descriptions for each level of use. After the medical visit, patients completed the Adolescent Diagnostic Interview (ADI), a structured diagnostic interview that yields diagnoses of abuse and dependence according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). On the basis of their past 12 months of alcohol and drug use on the ADI interview, adolescents were classified into 5 mutually exclusive diagnostic groups. "None" was defined by no reported use of alcohol or drugs during the past year. "Minimal use" was defined as use of alcohol or drugs but no report of any substance-related problems. "Problem use" was defined as reporting 1 or more substance-related problems but no diagnosis of abuse or dependence. "Abuse" was defined by meeting any 1 of 4 DSM-IV diagnostic criteria for either alcohol or drug abuse but no diagnosis of dependence. "Dependence" was defined by meeting any 3 of 7 diagnostic criteria for either alcohol or drug dependence, with or without a diagnosis of abuse. Proportions were compared using Fisher exact test. Agreement was assessed with the weighted kappa, and these analyses were stratified by substance used (ie, alcohol vs drug) and demographic characteristics. Sensitivity, specificity, and positive and negative predictive values were calculated from 2 x 2 tables. Compared with the criterion standard interview, providers identified significantly fewer patients with problem use and abuse and no patients with dependence. Of >100 patients whom the ADI classified with substance problem use, providers correctly identified 18. Of 50 patients who were classified with a diagnosis of alcohol or drug abuse, providers correctly identified 10. Of 36 patients who were classified with a diagnosis of alcohol or drug dependence, providers correctly identified none. For the 86 adolescents who were classified with a substance-related disorder (ie, abuse or dependence), providers' impressions were "none" (24.4%), "minimal use" (50%), "problem use" (15.1%), "abuse" (10.5%), and "dependence" (0%). There was only marginal agreement between providers' impressions and diagnoses related to alcohol use (kappa = .29), drug use (kappa = .31), and any substance use (kappa = .30). Kappa was not significantly affected by the patient's age, but it was by gender. Among boys, kappa was significantly higher for impressions of drug use versus alcohol use (kappa = .48 vs kappa = .27); and, among drug users, kappa was significantly higher among boys compared with girls (kappa = .48 vs kappa = .24). Kappa did not differ significantly across race/ethnicity subgroups, although there is a suggestive trend toward higher agreement for black non-Hispanic compared with white non-Hispanic adolescents (kappa = .35 vs kappa = .21). Kappa did not differ significantly on the basis of the visit type, but the size of this difference (kappa = .36 vs kappa = .24) suggests that the longer well-child visit yielded greater identification of substance-related pathology. Providers' impressions had a sensitivity of .63 for identifying use of alcohol or drugs. However, sensitivity was poor for identification of problem use (.14), abuse (.10), and dependence (0), whereas specificity and positive predictive values were high. Of the 86 adolescents with a diagnosis of abuse or dependence, 75.6% were correctly identified by providers as using substances; however, the level of use in 50% of these adolescents was reported by providers as minimal. In this study, clinical impressions of adolescents' alcohol/drug involvement underestimated substance-related pathology. When providers thought that use was present, there was a very high likelihood that a problem or disorder existed. The use of structured screening devices would likely improve identification of adolescents with substance-related pathology in primary care settings and should be considered for use with all adolescent patients, rather than only those who are perceived to be at higher risk.

Illicit drug abuse has crossed social, economic, and geographical borders, and remains one of the major health problems that modern society is facing worldwide. The role of multiple drug abuse as a basic for chromosome damage has been overlooked and it is important to determine its possible adverse health effects. This study aimed to compare the frequency of chromosomal damages between drug addicts and free drug controls. Cytogenetic study was obtained from 146 illicit drug-users and 200 free drug controls. Subjects were grouped into three categories depending on main drug of dependence. Cytogenetic studies on cultured lymphocytes showed an increase the frequency of chromosomal damages among addicts including opiate (5.89%), heroin (7.65%), and crystal (4.9%) when compared with drug free controls (1.45%). The frequency of chromosomal abnormalities was breaks, gaps, marker, and acentric, respectively. Our findings are also important as they are among the first to suggest here, illicit drug addiction continue to be significant public health problems in Iran.

As part of the evaluation of the Confederation's measures to reduce drug related problems, a review of available data on drug use and drug related problems in Switzerland has been conducted. Source of data included: population surveys (adults and teenagers), surveys among drug users, health statistics (drug related and AIDS related deaths, HIV case reporting, drug treatments) police statistics (denunciations for consumption). The aims of reducing the number of dependent hard drug users have been achieved where heroin is concerned. In particular, there seems to have been a decrease in the number of people becoming addicted to this substance. For all other illegal substances, especially cannabis, the trend is towards an increased use, as in many European countries. As regards dependent drug users, especially injecting drug users, progress has been made in the area of harm reduction and treatment coverage. This epidemiological assessment can be used in the discussions currently engaged about the revision of the Law governing narcotics and will be a baseline for future follow up of the situation.
Improving drug addiction treatment in China.
Tang, Yi-Lang; Hao, Wei
2007-07-01
To illustrate the current situation and problems of drug addiction in treatment China and propose suggestions. A descriptive study based on literature searched from Medline and the China National Knowledge Infrastructure database (1996-2007) and hand-picked references. Since the re-emergence of drug addiction in China in the early 1990s, there has been tremendous progress in drug addiction treatments in China, especially treatments for opiate addiction. However, many problems and challenges remain for improvement, including widespread negative attitudes towards drug abuse and drug-dependent individuals, the lack of evidence-based data on the efficacy of Chinese traditional medicine and the lack of a comprehensive and integrated system to organize all treatment resources and monitor treatment progress. The authors discuss the challenges that impede effective treatments of drug addiction and some suggestions are proposed. Implementing these suggestions can improve the outcome of treatment of drug-dependent individuals and benefit the whole society. China faces substantial drug addiction problems that appear to be worsening with time. Although much progress in drug addiction treatment has been made, improvement in many aspects is needed urgently.

Background Cross-sectional studies have demonstrated gender-related differences in the associations between problem-gambling severity and substance-use disorders; however, these associations have not been examined longitudinally. We aimed to examine the prospective associations between problem-gambling severity and incident substance-use disorders in women versus men. Methods Analyses were conducted using Wave-1 and Wave-2 NESARC data focusing on psychiatric diagnoses from 34,006 non-institutionalized US adults. Inclusionary criteria for pathological gambling were used to categorize Wave-1 participants as at-risk/problem gambling (ARPG) and non-ARPG (i.e. non-gambling/low-frequency gambling/low-risk gambling). Dependent variables included the three-year incidence of any substance-use disorder, alcohol-use disorders, nicotine dependence, drug-use disorders, prescription drug-use disorders, and illicit drug-use disorders. Results Significant gender-by-ARPG status interactions were observed with respect to the three-year incidence of nicotine dependence and prescription drug-use disorders, and approached significance with respect to incident alcohol-use disorders. ARPG (relative to non-ARPG) was positively associated with nicotine dependence among women (OR=2.00; 95% CI=1.24-3.00). ARPG was negatively associated with incident prescription drug-use disorders among men (OR=0.30; 95% CI=0.10-0.88)). Finally, ARPG was positively associated with incident alcohol-use disorders among men (OR=2.20; 95% CI=1.39-3.48). Conclusions Gambling problems were associated with an increased 3-year incidence of nicotine dependence in women and alcohol dependence in men. These findings highlight the importance of considering gender in prevention and treatment initiatives for adults who are experiencing gambling problems. Moreover, the specific factors underlying the differential progressions of specific substance-use disorders in women and men with ARPG warrant identification. PMID:23755930

OBJECTIVES: The authors examined Americans' opinions about financial and treatment competence of people with mental health problems, potential for harm to self or others, and the use of legal means to force treatment. METHODS: The 1996 General Social Survey provided interview data with a nationally representative sample (n = 1444). Respondents were given a vignette based on diagnostic criteria for schizophrenia, major depression, alcohol dependence, or drug dependence, or a "control" case. RESULTS: The specific nature of the problem was the most important factor shaping public reaction. Respondents viewed those with "troubles," alcohol dependence, or depression as able to make treatment decisions. Most reported that persons with alcohol or drug problems or schizophrenia cannot manage money and are likely to be violent toward others. Respondents indicated a willingness to coerce individuals into treatment. Respondent and other case characteristics rarely affected opinions. CONCLUSIONS: Americans report greater concern with individuals who have drug or alcohol problems than with persons who have other mental health problems. Evaluations of dangerousness and coercion indicate a continuing need for public education. PMID:10474550

Little is known about gender differences in methamphetamine (METH)-dependent users. The objective of this study was to examine potential gender differences in four domains: drug use history, psychological burden, current symptomology, and coping strategy. One hundred twenty four METH-dependent individuals (men; n = 75) were enrolled from substance use treatment programs. Participants filled out detailed questionnaires in the four domains. Men reported earlier first alcohol and drug use than women, but there was no difference in the age of first METH use or frequency of METH use. Women reported experiencing problems because of METH use at a younger age. Women were also more likely to have injected METH in the past year and they reported greater severity of drug problems compared to men. METH-dependent women had greater psychological burden, reported more use of an emotional-coping strategy, and had greater childhood emotional and sexual trauma. Overall, this study suggests that, unlike many other illicit drugs, severity of use and problems associated with use were not elevated in METH-dependent men compared to women. In fact, several factors indicated more severe patterns of use or risk factors in women.

We investigated the differential influence of family dysfunction on alcohol and methamphetamine dependence in Japan using the Addiction Severity Index (ASI), a useful instrument that multilaterally measures the severity of substance dependence. The participants in this study were 321 male patients with alcohol dependence and 68 male patients with methamphetamine dependence. We conducted semi-structured interviews with each patient using the ASI, which is designed to assess problem severity in seven functional domains: Medical, Employment/Support, Alcohol use, Drug use, Legal, Family/Social relationships, and Psychiatric. In patients with alcohol dependence, bad relationships with parents, brothers and sisters, and friends in their lives were related to current severe psychiatric problems. Bad relationships with brothers and sisters and partners in their lives were related to current severe employment/support problems, and bad relationships with partners in their lives were related to current severe family/social problems. The current severity of psychiatric problems was related to the current severity of drug use and family/social problems in patients with alcohol dependence. Patients with methamphetamine dependence had difficulty developing good relationships with their father. Furthermore, the current severity of psychiatric problems was related to the current severity of medical, employment/support, and family/social problems in patients with methamphetamine dependence. The results of this study suggest that family dysfunction differentially affects alcohol and methamphetamine dependence. Additionally, family relationships may be particularly related to psychiatric problems in these patients, although the ASI was developed to independently evaluate each of seven problem areas.

Given the high prevalence of child neglect among maltreatment subtypes, and its association with exposure to additional environmental adversity, understanding the processes that potentiate child neglect and link neglect to subsequent child externalizing psychopathology may shed light on key targets for preventive intervention. Among 170 urban low-income children (ages four-nine years) and their mothers, this five-year prospective study examined the effects of early neglect severity and maternal substance abuse, as well as neighborhood crime, on children’s later externalizing behavior problems. Severity of child neglect (up to age six years) mediated the relation between maternal drug dependence diagnosis, determined at children’s age of four, and children’s externalizing behavior problems at age nine. Rates of neighborhood crime mediated the link between presence of child neglect and children’s externalizing behavior problems. The roles of maternal drug dependence diagnosis, child neglect, and community violence in the development of child psychopathology are discussed in terms of their implications for intervention.

Understanding the disease of addiction.
Detar, D Todd
2011-03-01
Addiction is a chronic brain disease. Drug addiction manifests as a compulsive obsession to use a substance despite serious detrimental and sometimes irreversible consequences. Drug addiction is not the same as drug dependency because dependency may not manifest as an addictive behavior. This problem is fundamental to understanding the disease of addiction. This article discusses the neurobiology and genetics of drug addiction. Copyright © 2011. Published by Elsevier Inc.

We tested a structural model of relations among self-reported childhood maltreatment, alcohol and other drug abuse and dependence symptoms, and sexual risk behavior in a sample of adolescents receiving outpatient treatment of substance use problems. Structured interviews were administered to an ethnically diverse sample of 394 adolescents (114 girls, 280 boys; mean = 16.30 years; SD = 1.15 years; 44.9% Hispanic, 20.6% African American, 25.4% White non-Hispanic, and 9.1% other) in 2 outpatient treatment settings. Path analyses yielded findings consistent with a mediation model. Alcohol abuse and dependence symptoms mediated (1) relations between emotional neglect scores and sex with co-occurring alcohol use and (2) relations between sexual abuse scores and sex with co-occurring alcohol use. Drug abuse and dependence symptoms mediated relations between (1) neglect scores and (2) sexual intercourse with co-occurring alcohol or drug use, as well as unprotected sexual intercourse. Efforts to treat alcohol or drug use problems among adolescents or to prevent transmission of HIV or other sexually transmitted infections among youths with substance use problems may require tailoring treatment or prevention protocols to address client histories of maltreatment.

The relationship between violence and problem gambling in general population samples is under-researched and requires further attention to inform treatment and prevention efforts. We investigated the relationship between gambling problems and violence among men and sought to determine if the link can be accounted for by mental disorders, alcohol and drug dependence and impulsivity. A cross-sectional survey. A UK representative general population survey conducted in 2009. A total of 3025 UK men aged 18-64 years. Binary logistic regression was used to examine relationships. Outcome measures included gambling behaviour and self-reports of violence. Covariates included alcohol and drug dependence, mental illness, impulsivity and socio-demography. Problem gambling and probable pathological gambling were associated with increased odds of the perpetration of violence [adjusted odd ratios (AOR) = 3.09, confidence interval (CI) = 1.90-5.00 and 4.09, CI = 2.76-6.30, respectively] and a range of other behaviours, such as using a weapon (AORs = 4.93, CI = 2.52-9.63 and 6.33, CI = 3.52-11.38) and the perpetration of intimate partner violence (AOR = 9.80, CI =2.45-39.04). The results were attenuated when adjusted for comorbid mental illness and impulsivity, but remained statistically significant. Alcohol and drug dependence had the most impact; relationships were most attenuated when they added into the models, with the latter having the largest effect. Among men in the United Kingdom, self-reports of problem/pathological gambling remain predictive of a range of measures of violent behaviour after adjusting for alcohol and drug dependence, comorbid mental disorder and impulsivity; of the covariates, alcohol and drug dependence have the greatest effect in attenuating the gambling-violence association. © 2016 Society for the Study of Addiction.

Background and Aims Twin and family studies suggest that genetic influences are shared across substances of abuse. However, despite evidence of heritability, genome-wide association and candidate gene studies have indicated numerous markers of limited effects, suggesting that much of the heritability remains missing. We estimated (1) the aggregate effect of common single nucleotide polymorphisms (SNPs) on multiple indicators of comorbid drug problems that are typically employed across community and population-based samples, and (2) the genetic covariance across these measures. Participants 2596 unrelated subjects from the “Study of Addiction: Genetics and Environment” provided information on alcohol, tobacco, cocaine, cannabis, and other illicit substance dependence. Phenotypic measures included: (1) a factor score based on DSM-IV drug dependence diagnoses (DD), (2) a factor score based on problem use (PU; i.e., 1+ DSM-IV symptoms), and (3) dependence vulnerability (DV; a ratio of DSM-IV symptoms to the number of substances used). Findings Univariate and bivariate Genome-wide complex trait analyses of this selected sample indicated that common SNPs explained 25-36% of the variance across measures, with DD and DV having the largest effects [h2SNP (CI)=0.36 (0.11-0.62) and 0.33(0.07-0.58), respectively; PU = 0.25 (-0.01-0.51)]. Genetic effects were shared across the three phenotypic measures of comorbid drug problems (rSNP; rDD-PU = 0.92 (0.76-1.00), rDD-DV = 0.97 (0.87-1.00), and rPU-DV = 0.96 (0.82-1.00)). Conclusion At least 20% of the variance in the generalized vulnerability to substance dependence is attributable to common single nucleotide polymorphisms. The additive effect of common single nucleotide polymorphisms is shared across important indicators of comorbid drug problems. PMID:25424661

The aim of this study was to determine the effects of life-time tobacco, alcohol, and substance use on psychological and behavioral variables among 10th grade students in Istanbul/Turkey. This study employed a cross-sectional online self-report survey conducted in 45 schools from the 15 districts in Istanbul. The questionnaire featured a section about use of substances, including tobacco, alcohol, and drugs. The depression, anxiety, anger, assertiveness, sensation seeking and impulsiveness subscales of the Psychological Screening Test for Adolescents (PSTA) were used. The analyses were conducted based on 4957 subjects. Logistic regression analyses were conducted with each school with the related and behavioral variables as the dependent variables. Gender, tobacco, alcohol, and drug use being the independent variables. All four independent variables predicted the dependent variables. Lifetime tobacco and drug use had significant effects on all the subscale score, whereas lifetime alcohol use had significant effects on all the subscale scores other than lack of assertiveness, and male gender was a significant covariant for all the subscale scores. Drug use showed the highest effect on dependent variables. Interaction was found between effects of tobacco and alcohol on anxiety, whereas interactions were found between effects of tobacco and drugs on lack of assertiveness and impulsiveness. The findings suggested that male students with lifetime tobacco, alcohol or drug use have particularly high risk of psychological and behavioral problems. The unique effects of substance clusters on these problems may be useful in developing secondary preventive practices for substance use and abuse problems in Istanbul.
The Two Faces of Social Interaction Reward in Animal Models of Drug Dependence.
El Rawas, Rana; Saria, Alois
2016-03-01
Drug dependence is a serious health and social problem. Social factors can modify vulnerability to developing drug dependence, acting as risk factors or protective factors. Whereas stress and peer environment that encourage substance use may increase drug taking, strong attachments between family members and peer environment that do not experience drug use may protect against drug taking and, ultimately, drug dependence. The rewarding effects of drug abuse and social interaction can be evaluated using animal models. In this review we focus on evaluating social interaction reward in the conditioned place preference paradigm. We give an overview of how social interaction, if made available within the drug context, may facilitate, promote and interact with the drug's effects. However, social interaction, if offered alternatively outside the drug context, may have pronounced protective effects against drug abuse and relapse. We also address the importance of the weight difference parameter between the social partners in determining the positive or "agonistic" versus the hostile or "antagonistic" social interaction. We conclude that understanding social interaction reward and its subsequent effects on drug reward is sorely needed for therapeutic interventions against drug dependence.

Objective To identify robust predictors of drug dependence. Methods This longitudinal study included 2361 male and female twins from an ongoing longitudinal study at the Center for Antisocial Drug Dependence (CADD) at the University of Colorado Boulder and Denver campuses. Twins were recruited for the CADD project while they were between the ages of 12 and 18. Participants in the current study were on average approximately 15 years of age during the first wave of assessment and approximately 20 years of age at the second wave of assessment. The average time between assessments was five years. A structured interview was administered at each assessment to determine patterns of substance use and Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; Fourth Edition) attention deficit hyperactivity disorder (ADHD), conduct disorder (CD), and drug dependence symptoms. Cloninger’s Tridimensional Personality Questionnaire was also used to assess novelty seeking tendencies (NS). At the second wave of assessment, DSM-IV dependence symptoms were reassessed using the same interview. Path analyses were used to examine direct and indirect mechanisms linking psychopathology and drug outcomes. Results Adolescent substance use, CD, and NS predicted young adult substance dependence, whereas the predictive effects of ADHD were few and inconsistent. Furthermore, CD and NS effects were partially mediated by adolescent substance use. Conclusions Adolescent conduct problems, novelty seeking, and drug use are important indices of future drug problems. The strongest predictor was novelty seeking. PMID:23685327

Our objective was to explore communications from drug agencies about benzodiazepine dependence and selective serotonin reuptake inhibitors (SSRIs) withdrawal reactions over time. Documentary study. We searched the web-sites of the European Medicines Agency and the drug agencies in USA, UK, and Denmark for documents mentioning benzodiazepines or SSRIs. We supplemented with other relevant literature that could contribute to our study. The searches were performed in 2009 in PubMed, Google, BMJ and JAMA. It took many years before the drug regulators acknowledged benzodiazepine dependence and SSRI withdrawal reactions and before the prescribers and the public were informed. Drug regulators relied mainly on the definitions of dependence and withdrawal reactions from the diagnostic psychiatric manuals, which contributed to the idea that SSRIs do not cause dependence, although it is difficult for many patients to stop treatment. In the perspective of a precautionary principle, drug agencies have failed to acknowledge that SSRIs can cause dependence and have minimised the problem with regard to its frequency and severity. In the perspective of a risk management principle, the drug agencies have reacted in concordance with the slowly growing knowledge of adverse drug reactions and have sharpened the information to the prescribers and the public over time. However, solely relying on spontaneous reporting of adverse effects leads to underestimation and delayed information about the problems. Given the experience with the benzodiazepines, we believe the regulatory bodies should have required studies from the manufacturers that could have elucidated the dependence potential of the SSRIs before marketing authorization was granted.

The present study of homeless non-treatment-seeking problem drug users was designed to complement and extend previous studies which focused exclusively on treatment-seeking homeless problem drug users. Data were available for 866 primary care patients with drug problems, 30% homeless and 70% housed. In the 2 years prior to baseline, homeless participants had less chronic medical co-morbidity than problem drug users who were housed yet were significantly more likely to have used emergency department services, to have used them more frequently, and at higher cost. Compared to their housed counterparts, homeless participants were also more likely to have been admitted to specialized chemical dependency treatment and/or detoxification services, to have been arrested for a felony or gross misdemeanor, and to report having psychiatric problems in the prior 30 days. Additional support may be necessary for homeless patients presenting in primary care to benefit from substance abuse treatment given their more severe drug use problems coupled with their co-morbid health, psychiatric, and psychosocial problems.

Drug Craving Terminology among Opiate Dependents; A Mixed Method Study
Maarefvand, Masoomeh; Ghiasvand, Hamid Reza
2013-01-01
Objective Drug craving is defined as an urge to continue substance abuse. Drug dependents use different terms to express their subjective feeling of craving. This study was an attempt to generate an understanding of craving terminology among different groups of Persian speaking Iranian opiate dependents. Method Terms used for the meaning of drug craving were listed by 36 ex-opiate dependents in focus group discussion meetings in the first phase of the study. These terms were composed from Craving Terms Questionnaire. In the second phase, 120 subjects in 3 groups of opiate dependents and a group of Current Opiate Abusers rated usage frequency of each term in the questionnaire under a Twelve-Step Program, Methadone Maintenance, and Other Abstinence-based Programs. Results Eighty nine terms were categorized in stimulation and triggering, attention bias and obsession, decision making difficulty, information processing impairment, withdrawal induction, drug euphoric experience, mental urge, motor control problem, negative valancing and stigmatizing. Terms for the three categories of mental urge, attention bias and obsession and motor control problem were used more than others. Patients in Methadone Maintenance Treatment (MMT) group used different categories of craving terms in comparison to other groups. Abstinent cases reported higher total score for craving terms in comparison to other groups in Twelve-Step Program and other abstinence-based programs. Conclusion Each craving-related term is associated with some aspects of the multidimensional concept of craving. A drug-craving thesaurus could provide a better understanding of craving nature from a drug dependent point of view. There are differences among abstinence vs. maintenance based treated opiate dependents in using craving terms. Addiction therapists will benefit from accessing drug dependents’ lexicon to assess and create therapeutic alliance with their clients. PMID:24130609

Objectives. We tested a structural model of relations among self-reported childhood maltreatment, alcohol and other drug abuse and dependence symptoms, and sexual risk behavior in a sample of adolescents receiving outpatient treatment of substance use problems. Methods. Structured interviews were administered to an ethnically diverse sample of 394 adolescents (114 girls, 280 boys; mean = 16.30 years; SD = 1.15 years; 44.9% Hispanic, 20.6% African American, 25.4% White non-Hispanic, and 9.1% other) in 2 outpatient treatment settings. Results. Path analyses yielded findings consistent with a mediation model. Alcohol abuse and dependence symptoms mediated (1) relations between emotional neglect scores and sex with co-occurring alcohol use and (2) relations between sexual abuse scores and sex with co-occurring alcohol use. Drug abuse and dependence symptoms mediated relations between (1) neglect scores and (2) sexual intercourse with co-occurring alcohol or drug use, as well as unprotected sexual intercourse. Conclusions. Efforts to treat alcohol or drug use problems among adolescents or to prevent transmission of HIV or other sexually transmitted infections among youths with substance use problems may require tailoring treatment or prevention protocols to address client histories of maltreatment.

Despite the value of 12-step meetings, few studies have examined factors associated with attendance among those living with HIV/AIDS, such as the impact of HIV disease severity and demographics. This study examines predisposing characteristics, enabling resources and need on attendance at Alcoholic Anonymous (AA) and Narcotics Anonymous (NA) meetings among those living with HIV/AIDS and alcohol problems. Secondary analysis of prospective data from the HIV-Longitudinal Interrelationships of Viruses and Ethanol study, a cohort of 400 adults living with HIV/AIDS and alcohol problems. Factors associated with AA/NA attendance were identified using the Anderson model for vulnerable populations. Generalized estimating equation logistic regression models were fit to identify factors associated with self-reported AA/NA attendance. At study entry, subjects were 75% male, 12% met diagnostic criteria for alcohol dependence, 43% had drug dependence and 56% reported attending one or more AA/NA meetings (past 6 months). In the adjusted model, female gender negatively associated with attendance, as were social support systems that use alcohol and/or drugs, while presence of HCV antibody, drug dependence diagnosis, and homelessness associated with higher odds of attendance. Non-substance abuse related barriers to AA/NA group attendance exist for those living with HIV/AIDS, including females and social support systems that use alcohol and/or drugs. Positive associations of homelessness, HCV infection and current drug dependence were identified. These findings provide implications for policy makers and treatment professionals who wish to encourage attendance at 12-step meetings for those living with HIV/AIDS and alcohol or other substance use problems.

[Are there any sex/gender differences in drug use and drug addiction?].
Mendrek, Adrianna
Drug use and drug addiction have been traditionally considered to be a male problem, however the gender gap has been decreasing over the past few decades. Thus, while the prevalence of alcohol, cannabis and nicotine dependence is still overall greater among men than among women, sex/gender differences in the abuse of stimulants and opiates seem to have disappeared. Moreover, women appear to be more prone to develop drug dependence, suffer more severe physical and psychological consequences of drug abuse, and have more difficulties quitting the habit. Numerous psychological, socio-cultural and biological factors have been implicated in these changing statistics. For example, while a large proportion of men initiate drug use to induce feelings of elation, energy or focus, women frequently start taking drugs to alleviate pre-existing mental health problems, including high levels of stress, feelings of alienation, depression, anxiety, or post-traumatic stress disorder. This maladaptive self-medication strategy often results in a faster transition to a habitual drug use and eventually a more severe dependence. In addition, the socio-cultural norms (particularly in the Western society) have changed dramatically over the past few decades. Thus, while there is still a more severe stigma and prejudice against women who use drugs (especially if they are pregnant of have children), overall there is much greater acceptance of women's drug use than it was several decades ago. Moreover, women have much greater access to various drugs of abuse than they used to have. Finally, over the past couple of decades new research started emerging pointing to some neurobiological factors that could also contribute to sex differences in drug addiction. Thus, there is now evidence that dopamine system, which for decades has been strongly implicated in drug reinforcement, is sexually dimorphic. The number of dopaminergic neurons, the density of the dopaminergic terminals, as well as responsiveness of the dopaminergic system to drugs of abuse, has been shown to differ between males and females and it has been shown to be modulated by sex steroid hormones, especially estrogen. For example, female rats exhibit greater motivation to self-administer cocaine than male rats and their motivation is the highest during elevated levels of estrogen. All these psychological, socio-cultural and biological factors that contribute to sex/gender difference in drug use and drug dependence, should be considered while evaluating and treating individuals with drug addiction problem.

Prior research has demonstrated the dimensionality of alcohol, nicotine and cannabis use disorders criteria. The purpose of this study was to examine the unidimensionality of DSM-IV cocaine, amphetamine and prescription drug abuse and dependence criteria and to determine the impact of elimination of the legal problems criterion on the information value of the aggregate criteria. Factor analyses and Item Response Theory (IRT) analyses were used to explore the unidimensionality and psychometric properties of the illicit drug use criteria using a large representative sample of the U.S. population. All illicit drug abuse and dependence criteria formed unidimensional latent traits. For amphetamines, cocaine, sedatives, tranquilizers and opioids, IRT models fit better for models without legal problems criterion than models with legal problems criterion and there were no differences in the information value of the IRT models with and without the legal problems criterion, supporting the elimination of that criterion. Consistent with findings for alcohol, nicotine and cannabis, amphetamine, cocaine, sedative, tranquilizer and opioid abuse and dependence criteria reflect underlying unitary dimensions of severity. The legal problems criterion associated with each of these substance use disorders can be eliminated with no loss in informational value and an advantage of parsimony. Taken together, these findings support the changes to substance use disorder diagnoses recommended by the American Psychiatric Association's DSM-5 Substance and Related Disorders Workgroup.

Problem drug use the public health imperative: what some of the literature says.
Bevan, Gez
2009-12-16
With more than 200,000 problem drug users is contact with structured treatment services in England the public health imperative behind drug treatment is great. Problem drug use for many is a chronic and relapsing condition, where "cure" is often neither a reasonable or appropriate expectation and it can further be argued that in these circumstances problem drug use is no different from any number of chronic and enduring health conditions that are managed in the health care system and therefore should be conceptualised as such. A public health approach to drug treatment emphasises the need for drug users in or accessing treatment, to reduce their harmful drug use, reduce drug use related risks such as sepsis and overdose and stay alive for longer. However a public health perspective in relation to problem drug use isn't always either apparent or readily understood and to that end there is still a significant need to continue the arguments and debate that treatment and interventions for problem and dependent drug users need to extend beyond an individualistic approach. For the purposes of discussion in this article public and population health will be used interchangeably. A recognition and acceptance that a public and population health approach to the management of problem drug users is sound public health policy also then requires a long term commitment in terms of staffing and resources where service delivery mirrors that of chronic condition management.

Background Drug use is believed to be an important factor contributing to the poor health and increased mortality risk that has been widely observed among homeless individuals. The objective of this study was to determine the prevalence and characteristics of drug use among a representative sample of homeless individuals and to examine the association between drug problems and physical and mental health status. Methods Recruitment of 603 single men, 304 single women, and 284 adults with dependent children occurred at homeless shelters and meal programs in Toronto, Canada. Information was collected on demographic characteristics and patterns of drug use. The Addiction Severity Index was used to assess whether participants suffered from drug problems. Associations of drug problems with physical and mental health status (measured by the SF-12 scale) were examined using regression analyses. Results Forty percent of the study sample had drug problems in the last 30 days. These individuals were more likely to be single men and less educated than those without drug problems. They were also more likely to have become homeless at a younger age (mean 24.8 vs. 30.9 years) and for a longer duration (mean 4.8 vs. 2.9 years). Marijuana and cocaine were the most frequently used drugs in the past two years (40% and 27%, respectively). Drug problems within the last 30 days were associated with significantly poorer mental health status (-4.9 points, 95% CI -6.5 to -3.2) but not with poorer physical health status (-0.03 points, 95% CI -1.3 to 1.3)). Conclusions Drug use is common among homeless individuals in Toronto. Current drug problems are associated with poorer mental health status but not with poorer physical health status. PMID:20181248

Chapter 3. A multidimensional model for narrative analysis of substance use-related dependency.
Larsson, Sam; von Braun, Therese; Lilja, John
2013-11-01
This chapter examines the possibilities and limitations of using a narrative method as a framework within a multidimensional model for exploring and analyzing the use and misuse of alcohol and drugs. It is posited that a multidimensional model, based on narrative reasoning, can give a more detailed and specific understanding of substance users, who represent a heterogeneous population of people, and of substance use-related dependency problems. Such a model describes and analyses the drug-use related problems in a manner that provides holistic and important information and knowledge about the person by contextual and situation interaction processes which are involved in the use/misuse of alcohol and drugs. Tentative conclusions and unresolved critical issues are considered.

Only three FDA-approved pharmacological treatments exist for treating opiate dependence, all of which are underprescribed and underused. No FDA-approved pharmacological treatments exist for cocaine or methamphetamine dependence. More evidence-based, FDA-approved treatments are needed for treating drug dependence, but pharmaceutical companies are unlikely to pursue such research without government incentives. Today pharmaceutical companies primarily conduct research and development (R&D) related to "blockbuster" and rare diseases; drug dependence does not fall into either category. Further compounding the problem, pharmaceutical companies have been recently slashing risky areas of research, rather than adopting new areas. Fortunately, the government has a number of options to incentivize pharmaceutical R&D relating to drug dependence treatment, including the following: market exclusivity for new medications, tax breaks, priority review vouchers, liability reduction, and an advanced market commitment. © 2016 Elsevier Inc.

The aim of this work is to show evidence of the validity of the Health-Related Quality of Life for Drug Abusers Test (HRQoLDA Test). This test was developed to measure specific HRQoL for drugs abusers, within the theoretical addiction framework of the biaxial model. The sample comprised 138 patients diagnosed with opiate drug dependence. In this study, the following constructs and variables of the biaxial model were measured: severity of dependence, physical health status, psychological adjustment and substance consumption. Results indicate that the HRQoLDA Test scores are related to dependency and consumption-related problems. Multiple regression analysis reveals that HRQoL can be predicted from drug dependence, physical health status and psychological adjustment. These results contribute empirical evidence of the theoretical relationships established between HRQoL and the biaxial model, and they support the interpretation of the HRQoLDA Test to measure HRQoL in drug abusers, thus providing a test to measure this specific construct in this population.

Understanding for whom moderated drinking is a viable, achievable, and sustainable goal among those with a range of alcohol use disorders (AUD) remains an important public health question. Despite common acceptance as severe risk factors, there is little empirical evidence to conclude whether co-occurring mental health disorders or drug dependence contribute to an individual’s inability to successfully moderate his drinking. Utilizing secondary data analysis, the purpose of this study was to identify predictors of moderation among both treatment seeking and non-treatment seeking, primarily alcohol dependent, problem drinking men who have sex with men (MSM), with an emphasis on the high risk factors psychiatric comorbidity and drug dependence. Problem drinkers (N=187) were assessed, provided feedback about their drinking, given the option to receive brief AUD treatment or change their drinking on their own, and then followed for 15 months. Findings revealed that neither psychiatric comorbidity or drug dependence predicted ability to achieve moderation when controlling for alcohol dependence severity. Those who were younger, more highly educated, and had more mild alcohol dependence were more likely to achieve moderated drinking. Impact of treatment on predictors is explored. Limitations of this study and arenas for future research are discussed. PMID:22201219
The Problem of “Just for Fun”: Patterns of Use Situations among Active Club Drug Users
Starks, Tyrel J.; Golub, Sarit; Kelly, Brian C.; Parsons, Jeffrey T.
2010-01-01
Existing research has demonstrated the significance of situational antecedents to substance use. The current study used a cluster analytic approach to identify groups of club drug users who report using substances in similar situations (assessed by the Inventory of Drug Taking Situations) with longitudinal data from 400 active drug users. A three-cluster solution emerged in baseline data and was replicated in 12-month follow-up data. Groups were identified as Situationally Restricted, Pleasure Driven, and Situationally Broad users. Group differences were observed on measures of mental health, attitudes towards substance use, amount of substance use, and rates of substance dependence. Cluster membership predicted substance dependence after controlling for past dependence, current use, and current depression/anxiety. PMID:20696530

To study the association between drugs use with schizophrenia clinical manifestations. The sample consists of 82 out-patients with schizophrenia, between 18 and 45 years old. They were evaluated with Addiction Severity Index (ASI) and with Positive and Negative Syndrome Scale (PANSS). A 6 months follow up was carried out. 37,8% patients had lifetime drug dependence (including alcohol and others drugs except for tobacco). The prevalence of dependence for the different drugs were: opioids 9,8%, cocaine 11%, alcohol 29,3%, cannabis 24,4%, tobacco 68,3%, caffeine 15,9%. Drug dependent had more family and legal problems. At the multiple regression analysis it was observed that cannabis and tobacco dependence was associated with a decrease in the PANSS negative symptoms subscale, and on the contrary, alcohol dependence produces a similar intensity increase at that scoring. We don't detect any clinical relevance effects over positive symptoms. Cannabis and tobacco may improve schizophrenia negative symptoms or neuroleptic secondary effects or patients with few negative symptoms may have more predisposition to the use, on the contrary alcohol use can impairment those symptoms.
[Pharmacist as gatekeeper: combating medication abuse and dependence].
Shimane, Takuya
2013-01-01
The nonmedical use of medications, including psychotropic drugs, is a growing health problem in Japan. According to a nationwide survey of mental hospitals, the proportion of patients with sedative (mainly benzodiazepine)-related disorders has more than doubled over the last decade. An association between psychotropic drug overdose and suicide risk has also been reported. Furthermore, over-the-counter drug abuse is still a serious problem in Japan. In recent years, pharmacists have been expected to act as gatekeepers, making timely identifications of suicide risk or substance abuse and directing these individuals to appropriate medical care facilities. In August 2012, the revised Comprehensive Suicide Measures Act identified pharmacists as one professional group that should act as gatekeepers. This article begins by reviewing the fundamental terms involved in understanding the nonmedical use of medications, including abuse, dependence, and intoxication. The current situation of substance abuse and dependence is then introduced through a summary of several epidemiological surveys conducted in Japan. Finally, the role of pharmacists as gatekeepers in preventing substance abuse and dependence on medications is discussed.

The increase in drug abuse in South Africa has had major social implications in the country. Problems associated with drug dependency are poverty, unemployment, a heavier burden on the health care system, the disintegration of family systems and drug-related crimes. Another area of concern is the link between drug abuse and child abuse. While…

Gender differences in prison-based drug treatment participation.
Belenko, Steven; Houser, Kimberly A
2012-08-01
Prisons inmates have high rates of substance abuse and associated social and health problems, and a concomitant high need for drug treatment while incarcerated. Female inmates have an even greater treatment need, yet most inmates do not participate in treatment while incarcerated. Using data from a nationally representative sample of prison inmates, this article examines the impact of gender on prison treatment participation and gender differences in the factors associated with clinical treatment participation. Females were significantly more likely to participate in prison drug treatment than males, controlling for other factors. For both males and females, severity of drug problems predicted participation in treatment. For males but not females, race was associated with prison treatment participation, and among those with drug abuse or dependence, females with co-occurring mental health problems were more likely to participate in treatment. Implications for prison assessment and treatment policies, and future research, are discussed.
Drug choice as a self-handicapping strategy in response to noncontingent success.
Berglas, S; Jones, E E
1978-04-01
In two closely related experiments, college student subjects were instructed to choose between a drug that allegedly interfered with performance and a drug that allegedly enhanced performance. This choice was the main dependent measure of the experiment. The drug choice intervened between work on soluble or insoluble problems and a promised retest on similar problems. In Experiment 1, all subjects received success feedback after their initial problem-solving attempts, thus creating one condition in which the success appeared to be accidental (noncontingent on performance) and one in which the success appeared to be contingent on appropriate knowledge. Males in the noncontingent-success condition were alone in preferring the performance-inhibiting drug, presumably because they wished to externalize probable failure on the retest. The predicted effect, however, did not hold for female subjects. Experiment 2 replicated the unique preference shown by males after noncontingent success and showed the critical importance of success feedback.

To estimate the prevalence of mental health service use among US adults, examine the associations of mental health service use with health insurance coverage, mental health problems and drug use, and detect health disparities. This was a cross-sectional study with 5,434 adults receiving mental health service out of 37,424 adult respondents from the 2013 National Survey on Drug Use and Health. Weighted univariate and multiple logistic regression analyses were used to estimate the associations of potential factors with mental health service use. The overall prevalence of mental health services use was 14.7%. Our results showed that being female, aging, having a major depressive episode, serious psychological distress, and illicit drug or alcohol abuse/dependence were positively associated with mental health service use; whereas being African American, Asian or Hispanic ethnicity, married, and having any form of insurance were negatively associated with mental health service use . Stratified analysis by insurance types showed that Medicaid/CHIP, CHAMPUS, and other insurance were positively associated with mental health service use. Health insurance coverage, mental health problems, and drug abuse or dependence were associated with mental health service use in US adults. Furthermore, adults with different insurances had disparities in access of mental health service.
Psychological treatment of anabolic-androgenic steroid-dependent individuals.
Corcoran, J P; Longo, E D
1992-01-01
Anabolic-androgenic steroids (AAS) are synthetic derivatives of the sex hormone testosterone. Anabolic refers to the "growth-promoting" effect while androgenic refers to the "masculinizing" effect. It is becoming more evident that nonathletes as well as athletes are abusing AAS. Although the abuse of alcohol and other drugs contribute significantly to current chemical use problems in American society, AAS abuse is one of the fastest growing "new drug" problems facing secondary and higher education institutes of learning. The purpose of this discussion is to present working hypotheses regarding the psychological treatment of AAS dependent individuals. The treatment approach presented incorporates the approaches used with eating disorders, substance abuse/dependence, and narcissistic personality disorders. This paper considers some of the preliminary considerations for the first phase of treatment, some pitfalls to avoid, and therapist characteristics, as well as treatment modalities that might be helpful in the treatment of AAS-dependent individuals.

Pathways from alcoholism to recovery are documented; less often are those from drug addiction to alcoholism. Biographical approaches allow analyzing how people change their uses and talk about their trajectories of recovery. Three hundred and forty-one people (34% women) in the Paris area were questioned on their trajectories with a biographical questionnaire. Some open questions were aimed to understand the connection they made between events in their lives, how recovered they felt and what they considered strengths or obstacles. All the participants had stopped at least one product. Their mean age was 43, and 26% were over 50. How can the differences between one substance addicts and dual abusers be explained? Can we hypothesize a better result for the patients with a single dependence to alcohol in their lives for the following two reasons? (1) They could really be taken in charge for their alcoholism whereas the dual abusers mostly receive cared for their illicit drug problems with an under estimation of their problem with alcohol. In this case, they turn to alcohol after weaning themselves from their drug dependence so as to return to a social consumption, especially when they are given an opiate treatment. (2) Conversely could we suggest that the dual substance abusers had different trajectories from their childhood (more adverse events, more social difficulties, mental health problems), and that this accumulation explains their skipping from one substance or behaviour to another without any real recovery for decades? All respondents were polydrug users. Eighty-two had been dependent mainly on alcohol. One hundred and twenty-one people had been drug addicts (mostly heroin), which they had stopped on average ten years before the survey. The last group included 138 persons who had been heroin or cocaine addicts and alcoholics in their lives, a third of whom had been dependent on alcohol before their drug addiction (35%), a tenth on both at the same time (10%) and more than half of the users (55%) had turned from drug addiction to alcoholism. The group concerning alcohol dependence includes the oldest participants, on average 49.7, and 55% of them were abstinent at the survey. Conversely, the group "with no alcohol dependence" had mainly turned to opiate treatments. Their histories in dependence and in various social statuses also showed a longer duration out of employment, in sickness or invalidity, or in prison, for the drug dependents as opposed to the "mainly" alcoholics. The population with dual substance abuse experienced twice as many adverse childhood events as the others (P<0.005): it was the case for 19.5% in "mainly alcohol" dependence compared to 38.4% in dual abuse. The recovery capital gave a mean score of 7.56±2.35 (median 7). A score below 6 was considered low. The score was significantly different according to the dependence groups: while 7.3% of "mainly alcohol" dependents had a score below 6, this was the case for 30.4% of the dual group (with alcohol and drugs), and 19% for the "mainly drug dependence" group. Controlling ages, sexes and groups of dependence in a logistic regression, the risk of having a recovery capital below six was more than four times higher for the dual dependents as opposed to the "mainly alcohol" dependents. Some people stay for decades in drug addiction centers switching from one dependence to another. Their alcohol drinking should be addressed earlier to prevent them from turning to drinking excessively in order to wean themselves from their drug addiction. Copyright © 2016 L'Encéphale, Paris.

Motivational interviewing (MI) for the treatment of alcohol and drug problems is typically conducted over 1 to 3 sessions. The current work evaluates an intensive 9-session version of MI (Intensive MI) compared to a standard single MI session (Standard MI) using 163 methamphetamine (MA) dependent individuals. The primary purpose of this paper is to report the unexpected finding that women with co-occurring alcohol problems in the Intensive MI condition reduced the severity of their alcohol problems significantly more than women in the Standard MI condition at the 6-month follow-up. Stronger perceived alliance with the therapist was inversely associated with alcohol problem severity scores. Findings indicate that Intensive MI is a beneficial treatment for alcohol problems among women with MA dependence. © 2013.
Club drug use and dependence among young adults recruited through time-space sampling.
Parsons, Jeffrey T; Grov, Christian; Kelly, Brian C
2009-01-01
Ketamine, methylenedioxymethamphetamine (MDMA/ecstasy), cocaine, gamma-hydroxybutyrate (GHB), methamphetamine, and d-lysergic acid diethylamide (LSD/acid) have been identified as "club drugs" because of their link to club culture among young adults. Yet little is known about users' demographic differences in the prevalence of club drugs. This study sought to provide a comprehensive profile of users' demographic differences in prevalence of club drug use and dependence. Using time-space sampling, a stratified sample of 400 18- to 29-year-old club-going young adults was recruited into the Club Drugs and Health Project. Though participants reported using an array of club drugs, almost all participants (90.0%) were cocaine users. Although there were several sexual orientation and gender differences in recent drug exposure, patterns of use (measured in days) were fairly similar across gender, sexual orientation, and age. Finally, a majority of individuals (58.5%) met or exceeded criteria for club drug dependence, with most (61.7%) indicating cocaine was the one drug causing them significant problems. Cocaine is a major drug in club culture. It is essential to develop culturally appropriate drug education and prevention initiatives for young adults using club drugs.
Caffeine Use Disorder: A Comprehensive Review and Research Agenda.
Meredith, Steven E; Juliano, Laura M; Hughes, John R; Griffiths, Roland R
2013-09-01
Caffeine is the most commonly used drug in the world. Although consumption of low to moderate doses of caffeine is generally safe, an increasing number of clinical studies are showing that some caffeine users become dependent on the drug and are unable to reduce consumption despite knowledge of recurrent health problems associated with continued use. Thus, the World Health Organization and some health care professionals recognize caffeine dependence as a clinical disorder. In this comprehensive literature review, we summarize published research on the biological evidence for caffeine dependence; we provide a systematic review of the prevalence of caffeine dependence and rates of endorsement of clinically meaningful indicators of distress and functional impairment among habitual caffeine users; we discuss the diagnostic criteria for Caffeine Use Disorder-a condition for further study included in the Diagnostic and Statistical Manual of Mental Disorders ( 5 th ed .); and we outline a research agenda to help guide future clinical, epidemiological, and genetic investigations of caffeine dependence. Numerous controlled laboratory investigations reviewed in this article show that caffeine produces behavioral and physiological effects similar to other drugs of dependence. Moreover, several recent clinical studies indicate that caffeine dependence is a clinically meaningful disorder that affects a nontrivial proportion of caffeine users. Nevertheless, more research is needed to determine the reliability, validity, and prevalence of this clinically important health problem.

2018-01-01
The current study examined the cumulative risk, age of initiation, and functional impairments among adults with substance use problems (N = 1748) by child abuse status. Child abuse was associated with earlier initiation of marijuana, cocaine, and heroin use, and had greater risks for all the drugs studied (hazard ratios, 1.7–3.2). Furthermore, child abuse was associated with increased medical and functional impairments, including ER visits, health problems, drug dealing, drug dependence, and drug cravings. Provision of social services and parenting education during the perinatal period may prevent the long-term impact of child abuse on substance use and related impairments. The study’s limitations are noted. PMID:22780838

Background Even though the association between cigarette smoking and later substance use has been shown, there is still no compelling evidence that demonstrates the long-term effects in a high drug using community in African Americans. Few studies have examined the mediating mechanisms of the effect of adolescent cigarette smoking on the drug progression pathway. Objectives We examined the long-term influence of adolescent smoking on later illegal drug use in a cohort of urban African Americans, and the mediating role of educational attainment in the drug progression pathway. Methods The study used a longitudinal dataset from the Woodlawn Project that followed 1,242 African Americans from 1966–1967 (at age 6–7) through 2002–2003 (at age 42–43). We used the propensity score matching method to find a regular and a nonregular adolescent smoking group that had similar childhood characteristics; we used the matched sample to assess the association between adolescent smoking and drug progression, and the mediating role of educational attainment. Results Adolescent regular smokers showed significantly higher odds of using marijuana, cocaine, and heroin, having alcohol abuse problems and any drug dependence, and abuse problems in adulthood. We found that educational attainment mediated most of the drug progression pathway, including cigarette smoking, marijuana, cocaine and heroin use, and drug dependence or abuse problems in adulthood, but not alcohol abuse. Conclusions More focus needs to be put on high school dropout and development of interventions in community settings for African Americans to alter the pathway for drug progression for adolescents who use cigarettes regularly.

Tramadol abuse liability is underestimated and the evidence of abuse and dependence is emerging. It has many health and social consequences especially in adolescents. Tramadol abuse has not been well studied in Egypt. The aim of this study was to estimate the prevalence and associated correlates of tramadol use and abuse among school students in Egypt. A total of 204 students, aged 13-18 years, from six schools in Zagazig, Egypt, were screened for tramadol use using The Drug Use Disorders Identification Test and a urine screen for tramadol. The prevalence of tramadol use was 8.8% among school students and the average age at onset of tramadol use was 16.5 ± 1.1. Some 83% of the users were using tramadol alone while the rest (17%) were using a combination of tramadol, alcohol, and cannabis. Two-thirds of these students started with tramadol as the first drug after the onset of tobacco smoking. Over one third of tramadol users had drug-related problems and 6% had dependence. There was a significant association between tramadol use and older age, male gender, and smoking. Drug-related problems were negatively correlated with age at onset of tramadol use. Tramadol use was common among adolescents and over one third of tramadol users had drug-related problems. Population-based longitudinal studies are needed to investigate tramadol use and the possible role of tramadol as a gateway drug in the development of substance abuse in Egypt.
Validity of the Addiction Severity Index (adapted version) in a Costa Rican population group.

Until recently, no adapted and validated instrument was available for assessing the alcohol and drug problems of individuals in Costa Rica. This article reports the results of a study performed by Costa Rica's Institute on Alcoholism and Drug Dependence in order to test an adapted version of one such instrument, the Addiction Severity Index (ASI), in a Costa Rican setting. The instrument was used to interview 100 male subjects 18 to 64 years old (51 with diagnosed alcohol or drug problems and 49 controls). In general, the subjects with previously diagnosed alcohol or drug problems were assigned substantially higher scores. More specifically, statistical analysis indicated highly significant correlations (p less than 0.001) between the type of subject (test subject or control) and the likelihood that noteworthy problems would be found in the areas of alcohol use, family/social relations, work/finances, and psychological status. Overall, the study demonstrated that the instrument was capable of distinguishing between the affected and unaffected populations, and also of gauging the severity of the problems involved and the patients' treatment needs.

The links between gambling problems, trauma and life stressors are known to exist but understanding the extent of these relationships will allow for greater efficacy in early intervention and treatment. We investigated these relationships among men and sought to determine whether links were attenuated by alcohol and drug use problems. A cross-sectional UK representative general population survey was conducted in 2009 with 3025 men aged 18-64years. Measurements included self-reported gambling behaviours, as measured by the South Oaks Gambling Scale (SOGS) and traumatic or stressful life events. Covariates included alcohol and drug dependence and socio-demographics. Binary logistic regression models were used to examine associations. Problem gambling (SOGS 3-4) and probable pathological gambling (SOGS 5+) were associated with increased odds of trauma in childhood (e.g. violence in the home (Adjusted Odd Ratios (AOR) 3.0 (CI=1.8-5.0) and 2.6 (CI=1.7-4.1) respectively), and life stressors in adulthood (e.g. intimate partner violence (AORs 4.5 (CI=2.0-10.3) and 4.7 (CI=2.3-9.7) and homelessness (AORs 2.2 (CI=1.1-4.6) and 3.2 (CI=1.9-5.5)). Results were attenuated when adjusted for probable alcohol and drug dependence with the latter having largest effects. Among men in the United Kingdom, disordered gambling remains uniquely associated with trauma and life stressors in childhood and adulthood after adjusting for alcohol and drug dependence. The results support a need for disordered gambling treatment services to undertake routine screening for alcohol, drugs, IPV and traumatic life events and to tailor treatment that specifically targets the effects of stress for clients who present with such a cluster of issues.

Men who are violent toward their partners tend to have a dual problem with alcohol and drug use, yet little is known about differences between men with single rather than dual problems. This study was one of the first to evaluate differences between alcohol dependent men who were arrested for Intimate Partner Violence (IPV) with and without concurrent illicit drug use. Seventy-eight participants were randomly assigned to manual-guided group behavioral therapies (Cognitive Behavioral Therapy or Twelve Step Facilitation) and assessed across 12 weeks of treatment. Despite denying drug use at baseline, thirty-two clients (43%) tested positive for illicit drug use (cocaine and marijuana) during the 12 weeks of treatment. The study specifically addressed whether there were differences between clients using alcohol only versus individuals using both alcohol + drugs in terms of 1) baseline characteristics; 2) treatment compliance (e.g., attendance and substance use during treatment; and 3) treatment outcomes (alcohol, drug use, anger management, and aggression at the completion of treatment). The results showed that there were comparatively few differences between the alcohol versus the alcohol + drug using groups at baseline. Regarding treatment compliance and retention, alcohol + drug using participants attended significantly fewer sessions, had significantly fewer percent days abstinence from alcohol use, significantly more total days of positive breathalyzer results. Regarding treatment outcomes across anger management and aggression scores, the alcohol + drug using participants had significantly more impairments in anger management styles from pre- to post-treatment. However, there were no differences between the groups across verbal or physical aggression. Both groups improved in their verbal aggression from pre- to post-treatment. The findings suggest that alcohol dependent men who continue to use illicit drugs may require additional interventions to effectively control their drug use and, their anger management styles.
Mutant onco-proteins as drug targets: successes, failures, and future prospects.
McCormick, Frank
2011-02-01
Mutant onco-proteins play a direct, causal role in cancer and are therefore considered attractive drug targets. Clinical experience has supported this view, with some exceptions. However, clinical benefit has often been restricted by rapid emergence of drug-resistant clones through several distinct mechanisms. This problem can, in principle, be addressed through cocktails containing several drugs. However, the number of tumors whose survival is dependent on a single, druggable mutant onco-protein is currently unknown. The majority of tumors may be driven either by single drivers that are un-druggable, or by combinations of drivers. In both cases, new approaches will be necessary. Development of systemic RNA interference may be a solution to these problems. Copyright © 2010 Elsevier Ltd. All rights reserved.
Substance use in remand prisoners: a consecutive case study.
Mason, D.; Birmingham, L.; Grubin, D.
1997-01-01
OBJECTIVES: To determine the prevalence of drug and alcohol use among newly remanded prisoners, assess the effectiveness of prison reception screening, and examine the clinical management of substance misusers among remand prisoners. DESIGN: A consecutive case study of remand prisoners screened at reception for substance misuse and treatment needs and comparison of findings with those of prison reception screening and treatment provision. SETTING: A large adult male remand prison (Durham). SUBJECTS: 548 men aged 21 and over awaiting trial. MAIN OUTCOME MEASURES: Prevalence of substance misuse; treatment needs of substance misusers; effectiveness of prison reception screening for substance misuse; provision of detoxification programmes. RESULTS: Before remand 312 (57%) men were using illicit drugs and 181 (33%) met DSM-IV drug misuse or dependence criteria; 177 (32%) men met misuse or dependence criteria for alcohol. 391 (71%) men were judged to require help directed at their drug or alcohol use and 197 (36%) were judged to require a detoxification programme. The prison reception screen identified recent illicit drug use in 131 (24%) of 536 men and problem drinking in 103 (19%). Drug use was more likely to be identified by prison screening if an inmate was using multiple substances, using opiates, or had a diagnosis of abuse or dependence. 47 (9%) of 536 inmates were prescribed treatment to ease the symptoms of substance withdrawal. CONCLUSIONS: The prevalence of substance misuse in newly remanded prisoners is high. Prison reception health screening consistently underestimated drug and alcohol use. In many cases in which substance use is identified the quantities and numbers of different substances being used are underestimated. Initial management of inmates identified by prison screening as having problems with dependence producing substances is poor. Few receive a detoxification programme, so that many are left with the option of continuing to use drugs in prison or facing untreated withdrawal. PMID:9233320

The authors examined 3-year transitions among nonuse, asymptomatic use, and problem use of illicit drugs for U.S. adults in the general household population. Data were from the nationally representative National Epidemiologic Survey on Alcohol and Related Conditions, a study of 34,653 adults interviewed twice, 3 years apart. Respondents were categorized on three mutually exclusive categories of baseline drug status: past-year nonusers (N=32,675), past-year asymptomatic drug users (N=861), and past-year symptomatic drug users (N=1,117). Symptomatic drug use, or problem use, was defined as presence of one or more symptoms that operationalize DSM-IV drug abuse and dependence criteria. The authors assessed sociodemographic, health, substance use, and psychiatric covariates for association with 3-year transitions to different status categories. Among baseline nonusers, 95.4% continued to be nonusers at follow-up, 2.1% became asymptomatic users, and 2.5% developed problem use. Among baseline asymptomatic users, 66.6% had stopped using drugs at follow-up, 14.3% continued to be asymptomatic users, and 19.1% had developed problem use. Nearly half (49.0%) of those with problem use at baseline had stopped using drugs at follow-up, 10.9% had transitioned to asymptomatic use, and 40.1% continued to have problem use. Younger age, male sex, white race, and not being married were associated with progression from nonuse to use or problem use, as were alcohol and tobacco use and disorders, major depression, and schizotypal, borderline, and narcissistic personality disorders. Panic disorder and avoidant personality disorder were associated with less progression. Transitions in drug use status are common. The finding that alcohol and tobacco variables and co-occurring psychopathology are important correlates of transitions suggests the value of addressing all co-occurring disorders and substance use in patient assessments and treatment planning, both to prevent adverse transitions and to promote positive transitions.

Opioid receptors are critical therapeutic targets for medications development relevant to the treatment of drug dependence and pain. With recent advances in molecular neurobiology, it has become evident that the functional activity of opioid receptors, as ligand-regulated protein complexes, is modulated by multifarious intracellular and extracellular events, that there is genetic variation in coding for receptors, and that the activity of endogenous opioid systems may underlie actions common to other addictive disorders. This supplemental issue of Drug and Alcohol Dependence, arising from an invited symposium at the 71st Annual Meeting of the College on Problems of Drug Dependence, provides a series of contemporary reviews focused on recent advances in opioid neuropharmacology. Each speaker provides herein an invited comprehensive review of the state of knowledge on a specific topic in opioid neuropharmacology. Evans and colleagues describe the multi-faceted control of the opioid G-protein coupled receptor as a dynamic "sensor" complex and identify novel targets for drug development. von Zastrow focuses on opioid receptor-mediated events regulated by endocytosis and membrane trafficking through the endocytic pathway and differential responses to opioid agonists. Blendy and colleague provide a review of human association studies on the functional relevance of the mu opioid receptor variant, A118G, and presents data from the A112G knock-in model, an analogous mouse variant to A118G. Finally, Maldonado and colleagues provide a broader systems review from genetic, pharmacologic and behavioral studies implicating the endogenous opioid systems as a substrate for the mediation of substance use disorders spanning pharmacological classes.

On drug treatment and social control: Russian narcology's great leap backwards.
Elovich, Richard; Drucker, Ernest
2008-06-24
The medical discipline of narcology in Russia is a subspecialty of psychiatry from the Soviet era and it is given warrant to define the scope of health activities with regard to alcohol and other drug use, drug users, and related problems. Narcological practice is in turn constrained by the State. The emergence of widespread injection opiate use and associated HIV morbidities and mortalities during the first decade following the collapse of the Soviet Union has brought the contradictions in Russian narcological discourse into high relief. Narcology officials in the Russian Federation have consistently opposed substitution treatment for opiate dependence--the replacement of a short-acting illegal substance with a longer acting prescribed drug with similar pharmacological action but lower degree of risk. Thus, despite the addition of methadone and buprenorphine to WHO's list of essential medicines in 2005 and multiple position papers by international experts calling for substitution treatment as a critical element in the response to HIV (IOM, 2006; UNODC, UNAIDS, and WHO, 2005), methadone or buprenorphine remain prohibited by law in Russia. The authors detail Russian opposition to the prescription of methadone and buprenorphine, describing four phenomena: (1) the dominance of law enforcement and drug control policy over public health and medical ethics; (2) the conflation of Soviet era alcoholism treatment with treatment for opiate dependence; (3) the near universal representation of detoxification from drugs as treatment for dependence; and (4) a framework for judging treatment efficacy that is restricted to "cure" versus "failure to cure," and does not admit its poor outcomes or recognize alternative frameworks for gauging treatment of opiate dependence. In keeping with this position, Russian narcology officials have taken an implacable ideological stance toward illicit drug use, the people who use drugs, and their treatment. By adopting policies and practices totally unsupported by scientific evidence and inquiry, officials in Russia have rendered narcology (and medical practice) insensitive to the alarming rates and continued spread of HIV, with its dire morbidity and mortality rates in the Russian Federation, turning their backs on all the other health problems posed by opiate use and dependence itself.
Adolescent Alcoholism and Drug Addiction: The Experience of Parents.
Choate, Peter W
2015-10-29
Alcoholism and drug addiction have marked impacts on the ability of families to function. Much of the literature has been focused on adult members of a family who present with substance dependency. There is limited research into the effects of adolescent substance dependence on parenting and family functioning; little attention has been paid to the parents' experience. This qualitative study looks at the parental perspective as they attempted to adapt and cope with substance dependency in their teenage children. The research looks into family life and adds to family functioning knowledge when the identified client is a youth as opposed to an adult family member. Thirty-one adult caregivers of 21 teenagers were interviewed, resulting in eight significant themes: (1) finding out about the substance dependence problem; (2) experiences as the problems escalated; (3) looking for explanations other than substance dependence; (4) connecting to the parent's own history; (5) trying to cope; (6) challenges of getting help; (7) impact on siblings; and (8) choosing long-term rehabilitation. Implications of this research for clinical practice are discussed.

The effects of problems with alcohol and other drugs are sometimes subtle, sometimes extravagant, and always debilitating. The tendency for individuals to deny their own problems makes the need for firm and compassionate colleagues more important. Intervention is a way of bringing sympathetic help to a colleague in distress. (MLW)

Background There is a developing body of research looking at cannabis use opportunity, but little research examining timing of opportunity to use cannabis. Aims Identify factors associated with 1) earlier opportunity to use cannabis and 2) faster progression from opportunity to cannabis dependence. Method Cross-sectional study of 3824 Australian twins and siblings, measuring age of onset of cannabis use opportunity and DSM-IV cannabis dependence. Survival analysis identified factors associated with faster progression to opportunity or dependence. Results Factors associated with both speed of progression to opportunity and dependence were conduct disorder (opportunity HR 5.57, 95%CI 1.52–20.47; dependence HR 2.49, 95%CI 1.91–3.25), parental drug problems (opportunity HR 7.29, 95%CI 1.74–30.62; dependence HR 3.30, 95%CI 1.63–6.69), weekly tobacco use (opportunity HR 8.57, 95%CI 3.93–18.68; dependence HR 2.76, 95% CI 2.10–3.64), and female gender (opportunity HR 0.69, 95%CI 0.64–0.75; dependence HR 0.44, 95%CI 0.34–0.55). Frequent childhood religious attendance (HR 0.74, 95%CI 0.68–0.80), parental conflict (HR 1.09, 95%CI 1.00–1.18), parental alcohol problems (HR 1.19, 95%CI 1.08–1.30) and childhood sexual abuse (HR 1.17, 95%CI 1.01–1.34) were uniquely associated with transition to opportunity. Depressive episode (HR 1.44, 95%CI 1.12–1.85), tobacco dependence (HR 1.36, 95%CI 1.04 – 1.78), alcohol dependence (HR 2.64, 95%CI 1.53–4.58), other drug use (HR 2.10, 95%CI 1.64–2.69) and other drug dependence (HR 2.75, 95%CI 1.70–4.43) were uniquely associated with progression to dependence. Conclusion The profile of factors associated with opportunity to use cannabis and dependence only partially overlaps, suggesting targeting of interventions may benefit from being tailored to the stages of drug use.

Objective To examine 3-year transitions among nonuse, asymptomatic use and problem use of illicit drugs for US adults in the general household population. Method Data from the nationally representative NESARC study of 34,653 adults interviewed twice, 3 years apart. Three mutually exclusive categories of baseline drug status comprised past year non-users (n=32,675), past-year asymptomatic drug users (n=861), and past-year symptomatic drug users (n=1,117). Symptomatic drug use was defined as presence of one or more symptoms that operationalize DSM-IV drug abuse and dependence criteria. Variables tested for association with 3-year transitions to different status categories included sociodemographic, health, substance use and psychiatric covariates. Results Among baseline nonusers, 95.4% continued to be nonusers at follow-up, 2.1% became asymptomatic users, and 2.5% developed drug problems. Among baseline asymptomatic users, 66.6% had stopped using drugs at follow-up, 14.3% continued to be asymptomatic users and 19.1% had developed drug problems. Nearly half (49.0%) of those with drug problems at baseline had stopped using drugs at follow-up, 10.9% had transitioned to asymptomatic use and 40.1% continued to have drug problems. Younger age, male gender, white race, and not being married were associated with progression from non-use to use or problematic use, as were alcohol and tobacco categories, major depression and schizotypal, borderline and narcissistic personality disorders. Panic disorder and avoidant personality disorder were associated with less progression. Conclusions Transitions in drug use status are common. The finding that alcohol and tobacco-related variables and co-occurring psychopathology are important correlates of transitions suggests the value of addressing all co-occurring disorders and substance use in patient assessments and treatment planning, both for preventing adverse transitions and promoting positive transitions.

Use of nitrite inhalants ("poppers") among American youth.
Wu, Li-Tzy; Schlenger, William E; Ringwalt, Chris L
2005-07-01
We examined the patterns and correlates of nitrite inhalant use among adolescents aged 12 to 17 years. Study data were drawn from the 2000 and 2001 National Household Surveys on Drug Abuse. Logistic regression was used to identify the characteristics associated with nitrite inhalant use. Among adolescents aged 12 to 17 years, 1.5% reported any lifetime use of nitrite inhalants. The prevalence of lifetime nitrite inhalant use increased to 12% and 14% among adolescents who were dependent on alcohol and any drug in the past year, respectively. Many nitrite inhalant users used at least three other types of inhalants (68%) and also met the criteria for alcohol (33%) and drug (35%) abuse or dependence. Increased odds of nitrite inhalant use were associated with residing in nonmetropolitan areas, recent utilization of mental health services, delinquent behaviors, past year alcohol and drug abuse and dependence, and multi-drug use. Adolescents who had used nitrite inhalants at least once in their lifetime tend to engage in delinquent activities and report co-occurring multiple drug abuse and mental health problems in the past year.

This article summarizes the theoretical basis for targeted prevention programs as they apply to different high-risk groups. We explain the advantages and disadvantages of different definitions of risk and discuss strategies for preventing drug use related problems in high-risk youth. Productive prevention programs for many at-risk groups share similar components, including those that address motivation, skills, and decision making. We present key aspects of these three components and link them to theories in clinical psychology, social psychology, sociology, and chemical dependence treatment. Among a total of 29 promising targeted prevention programs, we describe examples of empirically evaluated, intensive interventions that have made a positive impact on the attitudes and behavior of multiple problem youth. Incorporating the perspectives of multiple disciplines appears essential for progress in drug abuse and other problem behavior prevention.

Phase II attrition remains the most important challenge for drug discovery. Tackling the problem requires improved understanding of the complexity of disease biology. Systems biology approaches to this problem can, in principle, deliver this. This article reviews the reports of the application of mechanistic systems models to drug discovery questions and discusses the added value. Although we are on the journey to the virtual human, the length, path and rate of learning from this remain an open question. Success will be dependent on the will to invest and make the most of the insight generated along the way. Copyright © 2015 Elsevier Ltd. All rights reserved.

Use of illicit substances of abuse is a major public health problem in developed countries like the US. However, this problem of illicit substance use has spread like a tumor to include currently developing countries where most of its youths and adolescents are actively engaged in this illegal practice. This problem is even more worse in poor resource countries, as use of these substances is accompanied with a lot of HIV- risk behaviours, and for cocaine and heroin drug injectors often share injecting equipments hence increasing the chances of contracting and spreading HIV infection. Apart from HIV infection, other infections include hepatitis B, C, abscesses and other ill-health problems such as drug dependence manifested with complex set of behaviours related to mental illnesses. For non-drug injectors, the chances of contracting and spreading HIV through their unsafe/unprotected sexual behaviours especially those having multiple partners is there. Use of these illicit substances have other consequences like compromising the dosing schedule or adherence / poor compliance to ARTs/ARVs among those enrolled. Furthermore, use of illicit substances may be accompanied with domestic sexual violence which is done without using any protective (condoms) measures) leading to HIV/AIDS and unplanned pregnancies. However, various studies and preventive approaches have been tried in the US on drug abusers in order to prevent the associated adverse health outcomes. There are many reasons why people use drugs. In many situations, drugs are being used as artificial problem-solvers such as frustrations, stress or tiredness. Drugs can often make a problem disappear for a short time but not usually the answer for solving the problem. They just help to remove it temporarily. Other people choose to use drugs to enjoy the feelings or for recreational purposes which many drugs produce. For example, many people, especially young people, experiment with using drugs to find out more about the sensations they produce. Drug use is a problem to users when it begins to cause some damage to their physical health, mental health and social well-being. These include mental illness, diseases caused by or related to use of drugs e.g. practice of sharing needles or syringes among drug injectors and also non-drug injectors may acquire HIV/AIDS and Hepatitis, crimes and violence. However, the number of harm associated with the use of drugs is increasing in Tanzania and other developing countries in Sub-Saharan Africa and globally in developed nations like the US and many others.
The current state of drug discovery and a potential role for NMR metabolomics.
Powers, Robert
2014-07-24
The pharmaceutical industry has significantly contributed to improving human health. Drugs have been attributed to both increasing life expectancy and decreasing health care costs. Unfortunately, there has been a recent decline in the creativity and productivity of the pharmaceutical industry. This is a complex issue with many contributing factors resulting from the numerous mergers, increase in out-sourcing, and the heavy dependency on high-throughput screening (HTS). While a simple solution to such a complex problem is unrealistic and highly unlikely, the inclusion of metabolomics as a routine component of the drug discovery process may provide some solutions to these problems. Specifically, as the binding affinity of a chemical lead is evolved during the iterative structure-based drug design process, metabolomics can provide feedback on the selectivity and the in vivo mechanism of action. Similarly, metabolomics can be used to evaluate and validate HTS leads. In effect, metabolomics can be used to eliminate compounds with potential efficacy and side effect problems while prioritizing well-behaved leads with druglike characteristics.
Benzodiazepine dependence among multidrug users in the club scene
Kurtz, Steven P.; Surratt, Hilary L.; Levi-Minzi, Maria A.; Mooss, Angela

Background Benzodiazepines (BZs) are among the most frequently prescribed drugs with the potential for abuse. Young adults ages 18–29 report the highest rates of BZ misuse in the United States. The majority of club drug users are also in this age group, and BZ misuse is prevalent in the nightclub scene. BZ dependence, however, is not well documented. This paper examines BZ dependence and its correlates among multidrug users in South Florida’s nightclub scene. Methods Data were drawn from structured interviews with men and women (N=521) who reported regular attendance at large dance clubs and recent use of both club drugs and BZs. Results Prevalences of BZ-related problems were 7.9% for BZ dependence, 22.6% BZ abuse, and 25% BZ abuse and/or dependence. In bivariate logistic regression models, heavy cocaine use (OR 2.27; 95% CI 1.18, 4.38), severe mental distress (OR 2.63; 95% CI 1.33, 5.21), and childhood victimization history (OR 2.43; 95% CI 1.10, 5.38) were associated with BZ dependence. Heavy cocaine use (OR 2.14; 95% CI 1.10, 4.18) and severe mental distress (OR 2.16; 95% CI 1.07, 4.37) survived as predictors in the multivariate model. Discussion BZ misuse is widespread among multidrug users in the club scene, who also exhibit high levels of other health and social problems. BZ dependence appears to be more prevalent in this sample than in other populations described in the literature. Recommendations for intervention and additional research are described. PMID:21708434

Nonmedical prescription drug use, defined as using the drug without a prescription or in ways for which it is not prescribed, and traumatic event exposure are highly prevalent among college students. Despite evidence that posttraumatic stress symptoms could place college students at risk for nonmedical prescription drug problems, no studies have examined this relationship. This study was a preliminary examination of posttraumatic stress symptoms, lifetime nonmedical prescription drug use, hazardous use, and dependence symptoms among college students with trauma exposure. Participants were students attending a rural college in Virginia, recruited through psychology classes, flyers, LISTSERVs, and announcements at student events. All students who reported experiencing at least one traumatic event were included (N = 119); participants' mean age was 19.7 years (SD = 1.90), about half were women (n = 63, 53%), and most were Caucasian (n = 103, 87%). Nearly 60% of participants (n = 71) reported using nonmedical prescription drugs at least once during their lifetime and were more likely than those with no use to report hazardous alcohol use (p < .01) and depressive symptoms (p < .05). There were no other significant differences between those who did and did not report use of nonmedical prescription drugs. Regression analyses showed that posttraumatic stress symptom frequency was positively associated with hazardous nonmedical prescription drug use, after controlling for gender, depressive symptoms, and hazardous alcohol use (p < .001). Posttraumatic stress symptom frequency was higher for those with any nonmedical prescription drug dependence symptoms (p < .001), but was unrelated to whether the student had ever engaged in nonmedical prescription drug use. Findings suggest that consideration of the types of behaviors and problems a college student is experiencing related to nonmedical prescription drug use may be more relevant to posttraumatic stress symptom frequency than dichotomous measures of nonmedical prescription drug use alone. Further, the association between the frequency of posttraumatic stress symptoms and both hazardous nonmedical prescription drug use and dependence symptoms among college students with a trauma history deserves further investigation due to the resulting vulnerability to increasingly negative outcomes.

This chapter explores the influence of the AA model on self-help fellowships addressing problems of drug dependence. Fellowships that have adapted the 12-step recovery model to other substances of abuse are reviewed; next similarities and differences between AA and drug-recovery 12-step organizations are examined; finally, we present empirical findings on patterns of attendance and perceptions of AA and Narcotics Anonymous (NA) among polydrug dependent populations, many of whom are cross-addicted to alcohol. Future directions in 12-step research are noted in closing. PMID:19115764

A family history (FH) of psychiatric and substance use problems is a potent risk factor for common internalizing and externalizing disorders. In a large web-based assessment of mental health in college students, we developed a brief set of screening questions for a FH of alcohol problems (AP), drug problems (DP) and depression-anxiety in four classes of relatives (father, mother, aunts/uncles/grandparents, and siblings) as reported by the student. Positive reports of a history of AP, DP, and depression-anxiety were substantially correlated within relatives. These FH measures predicted in the student, in an expected pattern, dimensions of personality and impulsivity, alcohol consumption and problems, smoking and nicotine dependence, use of illicit drugs, and symptoms of depression and anxiety. Using the mean score from the four classes of relatives was more predictive than using a familial/sporadic dichotomy. Interactions were seen between the FH of AP, DP, and depression-anxiety and peer deviance in predicting symptoms of alcohol and tobacco dependence. As the students aged, the FH of AP became a stronger predictor of alcohol problems. While we cannot directly assess the validity of these FH reports, the pattern of findings suggest that our brief screening items were able to assess, with some accuracy, the FH of substance misuse and internalizing psychiatric disorders in relatives. If correct, these measures can play an important role in the creation of developmental etiologic models for substance and internalizing psychiatric disorders which constitute one of the central goals of the overall project. © 2015 Wiley Periodicals, Inc.
Health practices, problems, and needs in a population of Micronesian adolescents.
Mayer, P A; Bauman, K A
1986-09-01
Saipan, one of many islands of the Pacific Trust Territory, depends on the United States for its medical care. The limited resources on the island have resulted in little medical attention for adolescents. This study surveyed 519 Saipan adolescents to determine their health practices, problems, and needs. Although these teenagers rarely saw physicians, they commonly reported health problems such as headaches, abdominal pain, and dental cavities. In the psychosocial arena, their problems involved parents, girlfriends/boyfriends, school, and suicidal thoughts. The health topics found to be of most interest included sex education, jobs, suicide prevention, drugs, and birth control. The most popular methods for learning about these subjects were books, movies, films, and school classes. There were high reported incidences of drug and alcohol problems among boys, and thoughts about suicide in all respondents.
Benzodiazepine Dependence among Young Adult Participants in the Club Scene Who Use Drugs.

Young adults ages 18-29 report the highest rates of benzodiazepine (BZD) misuse in the United States. The majority of club drug users are also in this age group, and BZD misuse is prevalent among participants in club scenes. This article examines BZD dependence and its correlates among young adult participants in the electronic dance music (EDM) culture in Miami, Florida, who use drugs. Structured interviews were with men and women (N = 356) ages 18 to 29 who reported regular attendance at EDM venues and recent use of both club drugs and BZDs. Prevalences of BZD-related problems were 12.6% for BZD dependence, 21.1% BZD abuse, and 24.2% BZD abuse and/or dependence. In a multivariate logistic regression model, younger age (OR 0.85; 95% CI 0.76, 0.96), severe mental distress (OR 8.30; 95% CI 3.07, 22.49), daily marijuana use (OR 2.10; 95% CI 1.03, 4.27), and heavy opioid use (OR 2.33; 95% CI 1.12, 4.83) were associated with BZD dependence. BZD dependence was higher in this sample than in other populations described in the literature. The links between BZD dependence, overdose history, and heavy opioid misuse are especially worrisome among this young sample. Recommendations for intervention and research are discussed.

2013-01-01
OBJECTIVE: To estimate the prevalence of female sexual dysfunction symptoms and the associated risk factors in a sample of patients with substance-related disorders admitted to a specialized in-patient care unit. METHODS: This study used a cross-section design, with eight months of data collection, conducted with substance-dependent women using structured questionnaires to collect socio-demographic data and identify their drug of choice. The Drug Abuse Screening Test, Short Alcohol Dependence Data questionnaire, Fagerström Test for Nicotine Dependence, and Arizona Sexual Experience Scale were also administered. RESULTS: The sample consisted of 105 women who had a mean age of 34.8 years (SD = 12.1, range = 18-65) and were predominantly heterosexual (74.3%), single (47.6%), Caucasian (50.5%), catholic (36.2%), and educated only to the level of primary education (40%), with a monthly family income of up to one minimum salary (37.5%). In 42.9% of the patients, crack was the drug of choice; 47.6% of the sample qualified for the Drug Abuse Screening Test (substantial problems related to drugs), 43.8% exhibited Short Alcohol Dependence Data (moderate or severe dependency), 47.6% exhibited Fagerström Test for Nicotine Dependence (high or very high nicotine dependence). The prevalence of sexual dysfunction symptoms was 34.2% (95% CI = [25.3, 44.1]), and a high level of nicotine dependence and low income increased the chances of having sexual dysfunction by 2.72-fold and 2.54 fold, respectively. An association was also observed between female sexual dysfunction symptoms and schooling and levels of drug dependence. CONCLUSIONS: Female sexual dysfunction symptoms were common among this sample and primarily associated with high levels of nicotine use. PMID:23525317

Genetic toxicology of abused drugs: a brief review.
Li, J H; Lin, L F
1998-11-01
Although numerous studies have been conducted on abused drugs, most focus on the problems of addiction (dependence) and their neurotoxicities. Now accumulated data have demonstrated that the genotoxicity and/or carcinogenicity of abused drugs can also be detrimental to our health. In this review, commonly abused substances, including LSD, opiates (diacetylmorphine, morphine, opium and codeine), cocaine, cannabis, betel quid and khat, are discussed for their potential genotoxicity/carcinogenicity. The available literature in the field, although not as abundant as for neurotoxicity, clearly indicates the capability of abused drugs to induce genotoxicity.
Mr. ATOD's wild ride: what do alcohol, tobacco, and other drugs have in common?
Courtwright, David T
2005-01-01
All researchers agree that individuals can become intoxicated by and dependent on alcohol, tobacco, and other psychoactive drugs. But they have disagreed over whether, and to what extent, drug pathologies comprise a unitary medical problem. Most critically, does addiction have a biological common denominator? Consensus on this question has shifted back and forth. In the late nineteenth and early twentieth centuries, physicians often studied and treated various drug addictions together, working under the "inebriety" paradigm. By the mid-twentieth century the inebriety paradigm had collapsed. Tobacco and alcohol had split off, both in the medical research community and in western popular culture. This article argues that neuroscientific, genetic, epidemiological, and historical evidence helped to reunify the addiction field in the late twentieth century. A new unifying paradigm emerged, variously called chemical dependency, substance abuse, or simply ATOD -- alcohol, tobacco, and other drugs.
Drug abuse in Costa Rica: a review of several studies.
Alfaro Murillo, E
1990-01-01
This article provides a review of drug use surveys conducted by Costa Rica's Institute on Alcoholism and Drug Dependence during the years 1983-1987. These studies dealt with a wide range of subjects--residents of marginal neighborhoods, juvenile male and adult female detainees, and high school students--as well as with the general population. Overall, the studies indicated that the most commonly used illicit drug was marijuana, that the bulk of the drug users (excluding alcohol and tobacco users) were young males, that relevant levels of cocaine use were starting to occur, and that the country's general drug abuse picture poses a problem in need of immediate attention.

Some drugs can stimulate or suppress appetite, whereas others can cause nausea and vomiting resulting in inadequate nutritional intake. Absorption of drugs is a complex process that can be affected by the physical characteristics of the gastrointestinal tract (GIT) as well. Depending on the physical properties of a drug, it may be absorbed in a limited area of the GIT or more diffusely along much of the entire length. Many diseases and conditions are also known to affect the GIT either directly or indirectly. Dietary factors also need to be considered when the "food" is an enteral formula. The widespread use of enteral tubes requires that consideration be given to patients receiving both enteral feedings and medication concurrently. The location of a tube in the gastrointestinal tract, as well as the problems involved in crushing and administering solid dosage forms, creates a unique set of problems.

Personality disturbances in drug-dependent women: relationship to childhood abuse.
Haller, Deborah L; Miles, Donna R
2004-05-01
This study examined associations between childhood abuse and personality disturbances in 228 drug-dependent women. Thirty-six percent denied abuse, 50% reported emotional, 42% physical, and 42% sexual abuse. Million Clinical Multiarial Inventory (MCMI-III) scores > 74 provided evidence of personality disturbance and scores on Minnesota Multiphasic Personality Inventory-2 (MMPI-2) scales measuring somatic complaints, depression, anxiety and postraumatic stress disorder (PTSD) served as covariates. Emotional and physical abuse survivors were at increased risk for borderline, masochistic, and avoidant disturbances and decreased risk for narcissistic disturbances. Emotional abuse survivors were also less likely to be sadistic whereas physical abuse survivors were more likely to be paranoid. Sexual abuse survivors were twice as likely be antisocial; however, no association was found with borderline personality. Finally, an increased prevalence of severe personality disturbances was observed among those experiencing multiple types of abuse. Childhood trauma predisposes drug-dependent women to develop troublesome personality characteristics that are independent of drug addiction and other psychological problems associated with childhood trauma.
Evaluating Dependence Criteria for Caffeine.
Striley, Catherine L W; Griffiths, Roland R; Cottler, Linda B

Background: Although caffeine is the most widely used mood-altering drug in the world, few studies have operationalized and characterized Diagnostic and Statistical Manual IV (DSM-IV) substance dependence criteria applied to caffeine. Methods: As a part of a nosological study of substance use disorders funded by the National Institute on Drug Abuse, we assessed caffeine use and dependence symptoms among high school and college students, drug treatment patients, and pain clinic patients who reported caffeine use in the last 7 days and also reported use of alcohol, nicotine, or illicit drugs within the past year ( n =167). Results: Thirty-five percent met the criteria for dependence when all seven of the adopted DSM dependence criteria were used. Rates of endorsement of several of the most applicable diagnostic criteria were as follows: 26% withdrawal, 23% desire to cut down or control use, and 44% continued use despite harm. In addition, 34% endorsed craving, 26% said they needed caffeine to function, and 10% indicated that they talked to a physician or counselor about problems experienced with caffeine. There was a trend towards increased caffeine dependence among those dependent on nicotine or alcohol. Within a subgroup that had used caffeine, alcohol, and nicotine in the past year, 28% fulfilled criteria for caffeine dependence compared to 50% for alcohol and 80% for nicotine. Conclusion: The present study adds to a growing literature suggesting the reliability, validity, and clinical utility of the caffeine dependence diagnosis. Recognition of caffeine dependence in the DSM-V may be clinically useful.
Punishing pregnant drug-using women: defying law, medicine, and common sense.
Flavin, Jeanne; Paltrow, Lynn M
2010-04-01
The arrests, detentions, prosecutions, and other legal actions taken against drug-dependent pregnant women distract attention from significant social problems, such as our lack of universal health care, the dearth of policies to support pregnant and parenting women, the absence of social supports for children, and the overall failure of the drug war. The attempts to "protect the fetus" undertaken through the criminal justice system (as well as in family and drug courts) actually undermine maternal and fetal health and discourage efforts to identify and implement effective strategies for addressing the needs of pregnant drug users and their families. In this article, the authors seek to expose some of the flawed premises on which the arrests, detentions, and prosecutions are based. The authors highlight the inherent unfairness of a system that expects low-income and drug-dependent pregnant women to provide their fetuses with the health care and safety that these women themselves are not provided and have not been guaranteed.

Emotion plays an important role in adapting to life changes and stressful events. Difficulty regulating emotions is one of the problems drug abusers often face, and teaching these individuals to express and manage their emotions can be effective on improving their difficult circumstances. The present study aimed to determine the effectiveness of the Gross model-based emotion regulation strategies training on anger reduction in drug-dependent individuals. The present study had a quasi-experimental design wherein pretest-posttest evaluations were applied using a control group. The population under study included addicts attending Marivan's methadone maintenance therapy centers in 2012 - 2013. Convenience sampling was used to select 30 substance-dependent individuals undergoing maintenance treatment who were then randomly assigned to the experiment and control groups. The experiment group received its training in eight two-hour sessions. Data were analyzed using analysis of co-variance and paired t-test. There was significant reduction in anger symptoms of drug-dependent individuals after gross model based emotion regulation training (ERT) (P < 0.001). Moreover, the effectiveness of the training on anger was persistent in the follow-up period. Symptoms of anger in drug-dependent individuals of this study were reduced by gross model-based emotion regulation strategies training. Based on the results of this study, we may conclude that the gross model based emotion regulation strategies training can be applied alongside other therapies to treat drug abusers undergoing rehabilitation.

Few stimulant drug users receive adequate treatment. This cross-sectional study describes the characteristics of female drug offenders that use stimulants and clarifies the factors related to the awareness of treatment for drug dependencies. We included 80 females imprisoned due to stimulant control law violations from 2012 to 2015. The characteristics of the female prisoners were stratified according to various treatment awareness levels, and associations between each characteristic and treatment awareness were evaluated using logistic regression models. The average period of stimulant drug use was 17.7 years. Participants imprisoned for the second time were significantly more likely to consider treatment compared to those imprisoned only once: odds ratio (OR) = 3.2 (95% confidence interval (CI): 1.0–10.7). This elevated OR was diluted in repeat offenders. Participants who had experienced multiple aftereffects (≥7) or serious depressive symptoms were also more likely to consider treatment: OR = 6.1 (95% CI: 1.8–20.8) and OR = 2.5 (95% CI: 1.0–6.2), respectively. Second-time stimulant offenders or offenders who had experienced health problems were more likely to consider it important to receive drug dependence treatment. To overcome relapses of stimulant use, it is recommended that stimulant use offenders are encouraged to accept adequate treatment. PMID:27845738

Risk factors among adolescent substance abusers have been shown to correlate with substance use severity. Characteristics related to severity, such as demographic and family factors, peer influences, psychiatric co-morbidity and HIV risk behaviors, are examined for a sample of adolescent cannabis users entering treatment. These data are from a clinical trial study utilizing blocked random assignment of clients to one of five treatment conditions. The study targeted adolescents entering outpatient treatment for primarily cannabis abuse or dependence. Treatment and research facilities in four metropolitan areas of the US were used to recruit study participants. Treatment was delivered in outpatient drug-free settings. Participants were 600 clients, ages 12-18, admitted to outpatient substance abuse treatment programs for cannabis problems, 96% with DSM-IV diagnoses of substance abuse or dependence, with the remaining 4% having at least one symptom of dependence plus significant problems indicating need for treatment. The Global Appraisal of Individual Needs (GAIN) was used to collect the information presented in this paper. The GAIN incorporates DSM-IV criteria for substance use disorders, conduct disorder and attention deficit hyperactivity disorder, as well as dimensional (scale) measures for physical and mental health. All participants reported at least one symptom of substance use disorders, and 46% met the DSM-IV criteria for substance dependence, while 50% met criteria for a diagnosis of abuse. Only 20% of the participants perceived any need for help with problems associated with their drug or alcohol use. Clients participating in the study typically presented multiple problems at treatment entry, most often including conduct disorder, attention deficit hyperactivity disorder (ADHD), internal (mental) distress, and physical health distress. The co-occurrence of conduct disorder and ADHD was found in 30% of the sample. Clients meeting criteria for substance dependence tended to have more co-occurring problems and significantly less denial at admission. The characteristics of this sample exemplify the complex nature of adolescent substance use and abuse among adolescents entering outpatient treatment programs. Patterns of co-occurring problems are at rates comparable to those found in other clinical studies. Those with more severe substance use disorders tend to manifest more problems of social functioning, more mental health problems, and physical health problems. Implications of these findings are discussed in terms of treatment needs, challenges, and prognostic implications.

Background Withdrawal, a diagnostic indicator of cannabis use disorder, is often minimized or ignored as a consequence of cannabis use, particularly among adolescents. This study aims to characterize cannabis withdrawal among adolescents in outpatient treatment for substance use disorder and evaluate the clinical significance of withdrawal as a predictor of substance-related outcomes. Methods Adolescent outpatients (N=127) reporting cannabis as their drug of choice (n=90) were stratified by presence of withdrawal and compared on demographic and clinical variables at treatment intake. Hierarchical linear models compared the effect of withdrawal on percent days abstinent (PDA) and related outcomes over a 1-year follow-up period. Results Adolescents reporting withdrawal (40%) were more likely to meet criteria for cannabis dependence, have higher levels of substance use severity, report more substance-related consequences, and have a mood disorder. Withdrawal was not associated with PDA over the follow-up period; however, this relationship was moderated by problem recognition such that adolescents reporting withdrawal and a drug problem improved at a greater rate with respect to PDA than those that didn’t recognize a problem with drugs and didn’t report withdrawal. Discussion Withdrawal is common among adolescent outpatients and is associated with a more clinically severe profile. In this sample, all adolescents reporting withdrawal met criteria for cannabis dependence, suggesting that withdrawal is a highly specific indicator of cannabis use disorder. While withdrawal doesn’t appear to be independently associated with substance use outcomes post-treatment, moderating factors such as drug problem recognition should be taken into account when formulating treatment and continuing care plans.

The high occurrence of childhood trauma in individuals with alcohol dependence is well-recognized. Nevertheless, researchers have rarely studied which types of childhood trauma often co-occur and how these combinations of different types and severities of childhood trauma are related to the patients' current addiction-related problems. We aimed to identify childhood trauma profiles in patients with alcohol dependence and examined relations of these trauma profiles with the patients' current addiction-related problems. In 347 alcohol-dependent patients, 5 types of childhood trauma (sexual abuse, physical abuse, emotional abuse, emotional neglect, and physical neglect) were measured using the Childhood Trauma Questionnaire. Childhood trauma profiles were identified using cluster analysis. The patients' current severity of addiction-related problems was assessed using the European Addiction Severity Index. We identified 6 profiles that comprised different types and severities of childhood trauma. The patients' trauma profiles predicted the severity of addiction-related problems in the domains of psychiatric symptoms, family relationships, social relationships, and drug use. Childhood trauma profiles may provide more useful information about the patient's risk of current addiction-related problems than the common distinction between traumatized versus nontraumatized patients.

People with substance dependence have health consequences, high health care utilization, and frequent comorbidity but often receive poor-quality care. Chronic care management (CCM) has been proposed as an approach to improve care and outcomes. To determine whether CCM for alcohol and other drug dependence improves substance use outcomes compared with usual primary care. The AHEAD study, a randomized trial conducted among 563 people with alcohol and other drug dependence at a Boston, Massachusetts, hospital-based primary care practice. Participants were recruited from September 2006 to September 2008 from a freestanding residential detoxification unit and referrals from an urban teaching hospital and advertisements; 95% completed 12-month follow-up. Participants were randomized to receive CCM (n=282) or no CCM (n=281). Chronic care management included longitudinal care coordinated with a primary care clinician; motivational enhancement therapy; relapse prevention counseling; and on-site medical, addiction, and psychiatric treatment, social work assistance, and referrals (including mutual help). The no CCM (control) group received a primary care appointment and a list of treatment resources including a telephone number to arrange counseling. The primary outcome was self-reported abstinence from opioids, stimulants, or heavy drinking. Biomarkers were secondary outcomes. There was no significant difference in abstinence from opioids, stimulants, or heavy drinking between the CCM (44%) and control (42%) groups (adjusted odds ratio, 0.84; 95% CI, 0.65-1.10; P=.21). No significant differences were found for secondary outcomes of addiction severity, health-related quality of life, or drug problems. No subgroup effects were found except among those with alcohol dependence, in whom CCM was associated with fewer alcohol problems (mean score, 10 vs 13; incidence rate ratio, 0.85; 95% CI, 0.72-1.00; P=.048). Among persons with alcohol and other drug dependence, CCM compared with a primary care appointment but no CCM did not increase self-reported abstinence over 12 months. Whether more intensive or longer-duration CCM is effective requires further investigation. clinicaltrials.gov Identifier: NCT00278447.
Strategic options for brand-name prescription drugs when patents expire.
Mehta, S C; Mehta, S S
1997-01-01
Pharmaceutical companies face a very hostile competitive environment from generic drugs once the patents on their brand name drugs expire. Depending on the country, such patents usually last 10-15 years but no sooner do the patents expire then copies of off-patent brand name drugs, called generics, are introduced, generally by smaller-size and lesser known companies, at significantly lower prices. As health care costs escalate all over the world, efforts to control medication costs have created a major market for generic prescription drugs, particularly in government funded hospitals and in dispensing general practitioner markets of the Asia Pacific and the third world. The world market for generics is estimated at US$20 billion, doubling in only five years and capturing over 30% of the market share. Because of adverse effects on sales and profitability due to the launching of generics, most research based companies that produce original brand-name patented drugs are forced to take counter measures to overcome this problem, particularly when R&D costs for new patents are skyrocketing. This paper develops a brief perspective on this problem and then examines the experiences of many multinational companies in the Singapore market in dealing with the problem. While several different approaches are identified, only one company experience appeared to work successfully and this is discussed in relative detail.
The Current State of Drug Discovery and a Potential Role for NMR Metabolomics
2015-01-01
The pharmaceutical industry has significantly contributed to improving human health. Drugs have been attributed to both increasing life expectancy and decreasing health care costs. Unfortunately, there has been a recent decline in the creativity and productivity of the pharmaceutical industry. This is a complex issue with many contributing factors resulting from the numerous mergers, increase in out-sourcing, and the heavy dependency on high-throughput screening (HTS). While a simple solution to such a complex problem is unrealistic and highly unlikely, the inclusion of metabolomics as a routine component of the drug discovery process may provide some solutions to these problems. Specifically, as the binding affinity of a chemical lead is evolved during the iterative structure-based drug design process, metabolomics can provide feedback on the selectivity and the in vivo mechanism of action. Similarly, metabolomics can be used to evaluate and validate HTS leads. In effect, metabolomics can be used to eliminate compounds with potential efficacy and side effect problems while prioritizing well-behaved leads with druglike characteristics. PMID:24588729
Exploring the nature of the relationship between child sexual abuse and substance use among women.
Jarvis, T J; Copeland, J; Walton, L
1998-06-01
This study investigated whether child abuse (CSA) was associated with earlier substance use and greater severity of substance dependence and what aspects of CSA might predict substance abuse. The study compared (a) drug and alcohol treatment clients with and without a history of CSA and (b) CSA survivors outside drug and alcohol treatment who did or did not have current substance abuse. Semi-structured interviews took place at participants' homes, treatment agencies or the research centre. Volunteer participants included 100 women recruited from drug and alcohol treatment programmes and 80 CSA survivors recruited through CSA counseling services and medial advertising. The results focus on data from the Opiate Treatment Index, Severity of Alcohol Dependence Questionnaire, Substance Dependence Scale, Self-Esteem Inventory and self-reported histories of CSA. There were no differences between CSA survivors and other drug and alcohol treatment clients in their severity of dependence. Women with a history of CSA more frequently identified stimulants as their main problem drug and reported an earlier age of first intoxication and earlier use of inhalants. Among abused CSA survivors outside drug and alcohol treatment, women with current substance abuse had typically been abused during adolescence by someone outside the family, whereas those without current substance abuse were typically abused by family members before adolescence. The results suggest that adolescence is a crucial time for the influence of CSA experiences on substance abuse.

This study examined the role of workplace mandates to chemical dependency treatment in treatment adherence, alcohol and drug abstinence, severity of employment problems, and severity of psychiatric problems. The sample included 448 employed members of a private, nonprofit U.S. managed care health plan who entered chemical dependency treatment with a workplace mandate (N=75) or without one (N=373); 405 of these individuals were followed up at one year (N=70 and N=335, respectively), and 362 participated in a five-year follow up (N=60 and N=302, respectively). Propensity scores predicting receipt of a workplace mandate were calculated. Logistic regression and ordinary least-squares regression were used to predict length of stay in chemical dependency treatment, alcohol and drug abstinence, and psychiatric and employment problem severity at one and five years. Overall, participants with a workplace mandate had one- and five-year outcomes similar to those without such a mandate. Having a workplace mandate also predicted longer treatment stays and improvement in employment problems. When other factors related to outcomes were controlled for, having a workplace mandate predicted abstinence at one year, with length of stay as a mediating variable. Workplace mandates can be an effective mechanism for improving work performance and other outcomes. Study participants who had a workplace mandate were more likely than those who did not have a workplace mandate to be abstinent at follow-up, and they did as well in treatment, both short and long term. Pressure from the workplace likely gets people to treatment earlier and provides incentives for treatment adherence.

Benefits of Exercise for the Quality of Life of Drug-Dependent Patients.
Giménez-Meseguer, Jorge; Tortosa-Martínez, Juan; de los Remedios Fernández-Valenciano, María
2015-01-01
This study combined quantitative and qualitative research methods to evaluate quality-of-life changes in drug-dependent patients after participation in a group-based exercise program. Quality of life (SF-36) and physical fitness (six-minute Walk Test, Timed Get Up and Go Test, and Chair Stand Test) were quantitatively determined in a group (n=37) of drug-dependent patients before and after a 12-week group exercise program (n=18) or routine care (n=19). Additionally, in-depth interviews were conducted at the end of the program with a subsample of 11 participants from the exercise group. Quantitative results showed improvements in fitness and different aspects of quality of life, such as physical function, mental health, vitality, social function, and general health perception. Qualitative results showed specific physical benefits (decreased injuries and muscle pain, decreased weight, and increased vitality with improvement in activities of daily living), psychological benefits (forgetting about everyday problems, improved mood, decreased stress and anxiety), social benefits, and a reduction in craving. The results of this study provide insight into the importance of exercise for the quality of life and recovery process of drug-dependent patients.
A Model for Pharmacological Research-Treatment of Cocaine Dependence
Montoya, Ivan D.; Hess, Judith M.; Preston, Kenzie L.; Gorelick, David A.
2008-01-01
Major problems for research on pharmacological treatments for cocaine dependence are lack of comparability of results from different treatment research programs and poor validity and/or reliability of results. Double-blind, placebo-controlled, random assignment, experimental designs, using standard intake and assessment procedures help to reduce these problems. Cessation or reduction of drug use and/or craving, retention in treatment, and medical and psychosocial improvement are some of the outcome variables collected in treatment research programs. A model to be followed across different outpatient clinical trials for pharmacological treatment of cocaine dependence is presented here. This model represents an effort to standardize data collection to make results more valid and comparable. PMID:8749725
An overview of aldehyde oxidase: an enzyme of emerging importance in novel drug discovery.
Rashidi, Mohammad-Reza; Soltani, Somaieh
2017-03-01
Given the rising trend in medicinal chemistry strategy to reduce cytochrome P450-dependent metabolism, aldehyde oxidase (AOX) has recently gained increased attention in drug discovery programs and the number of drug candidates that are metabolized by AOX is steadily growing. Areas covered: Despite the emerging importance of AOX in drug discovery, there are certain major recognized problems associated with AOX-mediated metabolism of drugs. Intra- and inter-species variations in AOX activity, the lack of reliable and predictive animal models using the common experimental animals, and failure in the predictions of in vivo metabolic activity of AOX using traditional in vitro methods are among these issues that are covered in this article. A comprehensive review of computational human AOX (hAOX) related studies are also provided. Expert opinion: Following the recent progress in the stem cell field, the authors recommend the application of organoids technology as an effective tool to solve the fundamental problems associated with the evaluation of AOX in drug discovery. The recent success in resolving the hAOX crystal structure can too be another valuable data source for the study of AOX-catalyzed metabolism of new drug candidates, using computer-aided drug discovery methods.

Alcohol and substance dependency are complex, problematic phenomena, which are growing worldwide. In particular, drug use and abuse among young people is a significant concern. Although addiction presents as a problem of dependent individuals, families are also profoundly affected by the family member's addiction. In this narrative literature review, we review published research from 1937 to 2014 to capture a narrative and historical perspective of addiction and family. We condense and analyze the experiences of parents with alcohol- and drug-dependent children, to emphasize the need for a more specific, in-depth exploration of mothers' experiences. Such exploration may advance nurses' understandings of individual, familial, and social complexities of parenting an addicted child. © The Author(s) 2014.
Circadian rhythms in effects of hypnotics and sleep inducers.
Reinberg, A
1986-01-01
Chronopharmacology involves the investigation of drug effects as a function of biological time and the investigation of drug effects on rhythm characteristics. Three new concepts must be considered: (a) the chronokinetics of a drug, embracing rhythmic (circadian) changes in drug bioavailability (or pharmacokinetics) and its excretion (urinary among others); (b) the chronaesthesia of a biosystem to a drug, i.e. circadian changes in the susceptibility of any biosystem to a drug (including organ systems, parasites, etc.); skin and bronchial chronaesthesia to various agents have been documented in man; and (c) the chronergy of a drug, taking into consideration its chronokinetics and the chronaesthesia of the involved organismic biosystems. The term chronergy includes rhythmic changes in the overall effects and in the effectiveness of some drugs. Clinical chronopharmacology is useful for solving problems of drug optimization, i.e. enhancing the desired efficiency of a drug and reducing its undesired effects. Circadian rhythms can be demonstrated in various effects of drugs on sleep, anaesthesia and related processes. For example, in the rat the duration of sleep induced by substances such as pentobarbital, hexobarbital, Althesin (alphaxadone and alphadoline in castor oil) is circadian system stage-dependent. Time-dependent changes of liver enzymes (e.g. hexobarbital oxidase) play a role in these circadian rhythms. The clinical chronopharmacokinetics of benzodiazepines have been documented in man. Chronopharmacologic methods can be used to study desired and undesired hypnotic effects of substances. Such is the case of new antihistamines (anti-H1), which do not induce sleepiness, in either acute or chronic administration. Pertinent also is the problem of intolerance to shift-work. Intolerant shift-workers are subject to internal desynchronization between at least two rhythms (e.g. activity-rest cycle and body temperature). Clinically these workers suffer from sleep disturbances, persistent fatigue and are regular users of sleeping pills, which is also a symptom of intolerance. However, over the long-term, these drugs are of no help to intolerant shift-workers.
Perceived unmet need and barriers to care amongst street-involved people who use illicit drugs.

Research on perceived unmet need for care for mental health and substance use problems focuses on general populations to the detriment of hidden populations. This study describes prevalence and correlates of perceived unmet need for care in a community-based sample of street-involved people who use illicit drugs and identifies barriers to care. A sample of 320 street-involved people who use drugs participated in a structured, interviewer-assisted survey in Edmonton, Canada. The survey included the Perceived Need for Care Questionnaire, which assessed unmet need for care for mental health and substance use problems across seven service types. Logistic regression examined the associations between perceived unmet need, extent of socioeconomic marginalisation and problem severity. Barriers underlying unmet service needs were also examined. Most (82%) participants reported unmet need for one or more services during the past year. Odds of reporting one or more unmet needs were elevated amongst participants reporting substantial housing instability (adjusted odds ratio = 2.37; 95% confidence interval 1.19-4.28) and amongst participants meeting criteria for drug dependence (adjusted odds ratio = 1.22; 95% confidence interval 1.03-1.50), even after adjustment for sociodemographic covariates. Structural, rather than motivational barriers were the most commonly reported reasons underlying unmet service needs. Street-involved people who use drugs experience very high rates of perceived unmet need for care for mental health and substance use problems. General population studies on perceived unmet need are insufficient for understanding needs and barriers to care in hidden populations.[Hyshka E, Anderson JT, Wild TC.

Addiction and the pharmacology of cannabis: implications for medicine and the law.
Lader, Malcolm
2009-01-01
The topic of drug addiction or misuse of drugs has numerous far-reaching ramifications into areas such as neuroscience, medicine and therapeutics, toxicology, epidemiology, national and international economics and politics, and the law. The general principles of drug addiction are first summarised. A recurring and intrinsic problem is lack of adequate characterisation of the independent variable, namely the drug taken. Secondly, it is not feasible to allocate subjects randomly to treatments. Thirdly, the heterogeneity of different forms of addiction precludes facile generalisations. "A problem drug user is anyone who experiences social, psychological, physical, or legal problems related to intoxication, and/or regular excessive consumption, and/or dependence as a consequence of their use of drugs" (UK Advisory Council on Misuse of Drugs, 1982). Cannabis is a genus of flowering plants whose products are used as recreational drugs. Claims have been made for a range of therapeutic properties. Its two main active principles are delta9 - tetrahydrocannabinol (THC) and cannabidiol (CBD). These compounds have contrasting pharmacological properties. THC is suspected of causing psychotic phenomena, but CBD seems more sedative and may even be antipsychotic. The past use of cannabis, particularly the concentrations of THC and CBD, can be monitored with hair analysis. Recent studies involving the administration of THC and CBD to human subjects are reviewed. Suggestions are made for further research into the pharmacology and toxicology of CBD. Such data may also point to a more rational evidence-based approach to the legal control of cannabis preparations.

This study assesses the frequency that users of illicit drugs display unprofessional behaviors in an employment setting. This research was conducted in the Therapeutic Workplace, a model employment-based treatment program for chronically unemployed adults with long-histories of illicit drug use. Unemployed adults in methadone treatment, who were opiate and cocaine dependent, showed signs of injection drug use, and recently used cocaine were hired to work for 4 hours every weekday for 7 months. Results show that while the overall incidence of many undesirable behaviors is low, a small percentage of participants had serious workplace behavior problems that might limit their success in community workplaces. This study suggests that unprofessional behavior in the workplace could contribute to chronic unemployment in this population. PMID:17668330
Genetic Variation of the Ghrelin Signalling System in Individuals with Amphetamine Dependence
Jayaram-Lindström, Nitya; Nilsson, Staffan; Toren, Kjell; Rosengren, Annika; Engel, Jörgen A.; Franck, Johan
2013-01-01
The development of amphetamine dependence largely depends on the effects of amphetamine in the brain reward systems. Ghrelin, an orexigenic peptide, activates the reward systems and is required for reward induced by alcohol, nicotine, cocaine and amphetamine in mice. Human genetic studies have shown that polymorphisms in the pre-proghrelin (GHRL) as well as GHS-R1A (GHSR) genes are associated with high alcohol consumption, increased weight and smoking in males. Since the heritability factor underlying drug dependence is shared between different drugs of abuse, we here examine the association between single nucleotide polymorphisms (SNPs) and haplotypes in the GHRL and GHSR, and amphetamine dependence. GHRL and GHSR SNPs were genotyped in Swedish amphetamine dependent individuals (n = 104) and controls from the general population (n = 310). A case-control analysis was performed and SNPs and haplotypes were additionally tested for association against Addiction Severity Interview (ASI) composite score of drug use. The minor G-allele of the GHSR SNP rs2948694, was more common among amphetamine dependent individuals when compared to controls (pc = 0.02). A significant association between the GHRL SNP rs4684677 and ASI composite score of drug use was also reported (pc = 0.03). The haplotype analysis did not add to the information given by the individual polymorphisms. Although genetic variability of the ghrelin signalling system is not a diagnostic marker for amphetamine dependence and problem severity of drug use, the present results strengthen the notion that ghrelin and its receptor may be involved in the development of addictive behaviours and may thus serve as suitable targets for new treatments of such disorders.

The development of amphetamine dependence largely depends on the effects of amphetamine in the brain reward systems. Ghrelin, an orexigenic peptide, activates the reward systems and is required for reward induced by alcohol, nicotine, cocaine and amphetamine in mice. Human genetic studies have shown that polymorphisms in the pre-proghrelin (GHRL) as well as GHS-R1A (GHSR) genes are associated with high alcohol consumption, increased weight and smoking in males. Since the heritability factor underlying drug dependence is shared between different drugs of abuse, we here examine the association between single nucleotide polymorphisms (SNPs) and haplotypes in the GHRL and GHSR, and amphetamine dependence. GHRL and GHSR SNPs were genotyped in Swedish amphetamine dependent individuals (n = 104) and controls from the general population (n = 310). A case-control analysis was performed and SNPs and haplotypes were additionally tested for association against Addiction Severity Interview (ASI) composite score of drug use. The minor G-allele of the GHSR SNP rs2948694, was more common among amphetamine dependent individuals when compared to controls (pc = 0.02). A significant association between the GHRL SNP rs4684677 and ASI composite score of drug use was also reported (pc = 0.03). The haplotype analysis did not add to the information given by the individual polymorphisms. Although genetic variability of the ghrelin signalling system is not a diagnostic marker for amphetamine dependence and problem severity of drug use, the present results strengthen the notion that ghrelin and its receptor may be involved in the development of addictive behaviours and may thus serve as suitable targets for new treatments of such disorders.

Many babies in the UK are born to drug-dependent parents, and dependence on psychoactive drugs during the postnatal period is associated with high rates of child maltreatment, with around a quarter of these children being subject to a child protection plan. Parents who are dependent on psychoactive drugs are at risk of a wide range of parenting problems, and studies have found reduced sensitivity and responsiveness to both the infant's physical and emotional needs. The poor outcomes that are associated with such drug dependency appear to be linked to the multiple difficulties experienced by such parents.An increase in understanding about the crucial importance of early relationships for infant well-being has led to a focus on the development and delivery of services that are aimed at supporting parenting and parent-infant interactions. The Parents under Pressure (PuP) programme is aimed at supporting parents who are dependent on psychoactive drugs or alcohol by providing them with methods of managing their emotional regulation, and of supporting their new baby's development. An evaluation of the PuP programme in Australia with parents on methadone maintenance of children aged 3 to 8 years found significant reductions in child abuse potential, rigid parenting attitudes and child behaviour problems. The study comprises a multicentre randomised controlled trial using a mixed-methods approach to data collection and analysis in order to identify which families are most able to benefit from this intervention.The study is being conducted in six family centres across the UK, and targets primary caregivers of children less than 2.5 years of age who are substance dependent. Consenting participants are randomly allocated to either the 20-week PuP programme or to standard care.The primary outcome is child abuse potential, and secondary outcomes include substance use, parental mental health and emotional regulation, parenting stress, and infant/toddler socio-emotional adjustment scale. This is one the first UK studies to examine the effectiveness of a programme targeting the parenting of substance-dependent parents of infants and toddlers, in terms of its effectiveness in improving the parent-infant relationship and reducing the potential for child abuse.

Few studies have focused on Asian Americans and Pacific Islanders (AAPIs), despite indications of increasing substance abuse among AAPIs in recent years. This prospective longitudinal study examined gender differences among AAPIs in treatment. The study included 567 (177 women, 390 men) AAPI patients drawn from two prior studies, one with 32 community treatment programs in 13 California counties (CalTOP, 3, 9 months), and another project including 36 treatment sites in 5 California counties (TSI, 3, 12 months). Baseline and follow-up assessments utilized the Addiction Severity Index(ASI). A subset of patients was assessed at 3 and 9/12 months (n = 106). Significant gender-related differences were observed at baseline: fewer women than men were employed or never married. More women were living with someone having alcohol and drug problems. Methamphetamine was the primary drug for women and men, followed by alcohol and heroin. Compared to AAPI men, AAPI women reported greater problem severity in family/social relationships (0.18 vs. 0.11, p <.001), employment (0.68 vs. 0.56, p <.001), and mental health (0.19 vs. 0.14, p <.01). Relative to women, AAPI men reported greater treatment satisfaction at the 3-month follow-up. Significant improvements at follow-up were observed in family, alcohol, drug, and legal domains for both genders, and in mental health for men only. Compared to AAPI men, AAPI women demonstrated significantly greater improvements in drug problems (ΔASI = 0.07, p <.05). Gender differences revealed in this study suggest a need for a greater treatment focus on psychiatric problems for AAPI women and drug use problems for AAPI men.

Background Emotion plays an important role in adapting to life changes and stressful events. Difficulty regulating emotions is one of the problems drug abusers often face, and teaching these individuals to express and manage their emotions can be effective on improving their difficult circumstances. Objectives The present study aimed to determine the effectiveness of the Gross model-based emotion regulation strategies training on anger reduction in drug-dependent individuals. Patients and Methods The present study had a quasi-experimental design wherein pretest-posttest evaluations were applied using a control group. The population under study included addicts attending Marivan’s methadone maintenance therapy centers in 2012 - 2013. Convenience sampling was used to select 30 substance-dependent individuals undergoing maintenance treatment who were then randomly assigned to the experiment and control groups. The experiment group received its training in eight two-hour sessions. Data were analyzed using analysis of co-variance and paired t-test. Results There was significant reduction in anger symptoms of drug-dependent individuals after gross model based emotion regulation training (ERT) (P < 0.001). Moreover, the effectiveness of the training on anger was persistent in the follow-up period. Conclusions Symptoms of anger in drug-dependent individuals of this study were reduced by gross model-based emotion regulation strategies training. Based on the results of this study, we may conclude that the gross model based emotion regulation strategies training can be applied alongside other therapies to treat drug abusers undergoing rehabilitation.

To explore health problems and the accessing of health services by frequent legal high users under an interim regulated legal market in central Auckland. Frequent legal high users (monthly+) were recruited from outside eight randomly-selected, licensed, legal high stores in central Auckland from 23 April-7 May, 2014. Eligible participants were emailed a unique invitation to complete an on-line survey; 105 completed the survey. Twenty-seven percent had suffered mental illness during their lifetimes. Eighty percent used synthetic cannabinoids (SC), and 20% 'party pills'. Forty-seven percent of SC users used daily or more often. Other drugs used included alcohol (80%), cannabis (59%), 'ecstasy' (18%) and methamphetamine (15%). Fifty-eight percent of SC users were classified as SC dependent. The most common problems reported from SC use were: insomnia (29%); 'vomiting/nausea' (25%); 'short temper/agitation' (21%); 'anxiety' (21%); 'strange thoughts' (16%); and 'heart palpitations' (14%). The health services most commonly accessed by SC users were: a 'doctor/GP' (9%); 'counsellor' (9%); 'DrugHelp/MethHelp' websites (7%); 'Alcohol & Drug Helpline' (4%); 'ambulance' (3%); 'A&E' (3%); and hospitalisation (3%). Frequent use of interim licensed SC products was associated with health problems, including dependency. Further research is required to determine the health risks of these products.

We use a one-dimensional two layer model with a semi-permeable membrane to study the diffusion of a therapeutic drug delivered from a drug-eluting stent (DES). The rate of drug transfer from the stent coating to the arterial wall is calculated by using underdamped Langevin dynamics simulations. Our results reveal that the membrane has virtually no delay effect on the rate of delivery from the DES. The work demonstrates the great potential of underdamped Langevin dynamics simulations as an easy to implement, efficient, method for solving complicated diffusion problems in systems with a spatially-dependent diffusion coefficient.

Prescription opioid (PO) dependence is a critical health problem. Although examination of drug cue reactivity paradigms has advanced the understanding of risk factors for relapse for a variety of substances (e.g., cocaine, alcohol, nicotine), no PO specific drug cue paradigm has been developed. The current study addressed this gap in the literature and evaluated the ability of a newly developed PO drug cue paradigm to elicit subjective, physiological, and neuroendocrine changes among PO-dependent participants (n = 20) as compared to controls (n = 17). The drug cue paradigm included an induction script, viewing and handling paraphernalia (e.g., bottle of oxycontin pills, pill crusher) and watching a video depicting people using POs as well as places related to POs (e.g., pharmacies). Consistent with hypotheses, the PO group demonstrated significant pre- to post-cue increases on subjective ratings of craving, difficulty resisting POs, stress, and anger. The control group did not demonstrate significant changes on any of the subjective measures. Both the PO group and the control group evidenced significant pre- to post-cue increases in physiological responses (e.g., blood pressure, skin conductance), as expected given the arousing nature of the drug cue stimuli. The PO group, but not the control group, evidenced a significant pre- to post-cue increase in heart rate and salivary cortisol levels. The development and validation of a drug cue paradigm for POs may help inform future research and treatment development efforts for patients with PO dependence. PMID:24813546

Objective This study examined the role of workplace mandates to chemical dependency treatment in treatment adherence, alcohol and drug abstinence, severity of employment problems, and severity of psychiatric problems. Methods The sample included 448 employed members of a private, nonprofit U.S. managed care health plan who entered chemical dependency treatment with a workplace mandate (N=75) or without one (N=373); 405 of these individuals were followed up at one year (N=70 and N=335, respectively), and 362 participated in a five-year follow up (N=60 and N=302, respectively). Propensity scores predicting receipt of a workplace mandate were calculated. Logistic regression and ordinary least-squares regression were used to predict length of stay in chemical dependency treatment, alcohol and drug abstinence, and psychiatric and employment problem severity at one and five years. Results Overall, participants with a workplace mandate had one- and five-year outcomes similar to those without such a mandate. Having a workplace mandate also predicted longer treatment stays and improvement in employment problems. When other factors related to outcomes were controlled for, having a workplace mandate predicted abstinence at one year, with length of stay as a mediating variable. Conclusions Workplace mandates can be an effective mechanism for improving work performance and other outcomes. Study participants who had a workplace mandate were more likely than those who did not have a workplace mandate to be abstinent at follow-up, and they did as well in treatment, both short and long term. Pressure from the workplace likely gets people to treatment earlier and provides incentives for treatment adherence. PMID:19411353

Introduction Drug addiction is one of the most flagrant social damages that can easily enervate the socio-cultural foundation of a country as well as endanger human dynamism. One of the prevalent problems among most addicted people is their low hope and relapse of drug dependence. The aim of this study was to assess the effect of vocational consultation (for training on problem-solving skills) on hope and relapse rate of patients treated in methadone maintenance clinics. Methods This experiment was conducted on 60 drug abusers treated in a methadone maintenance program in drug addiction centers in Bojnurd, Iran, in 2014. The patients were randomly and equally allocated into two study and control groups. All patients completed the Miller Hope Questionnaire before and after the intervention. Ten sessions of vocational consultation were held for the study group while the control group received no special treatment. Patients were followed up on for relapses for six months. Data were analyzed using SPSS (version 16) and the paired-samples t-test technique. Results The results indicated that the mean and standard deviation of hope on the pre-test in the study group increased on the post-test (from M=175.5, SD=31.8, to M=198.5, SD=20.4), while in the control group the mean of hope decreased from the pre-test to past-test stage (M=184.7, SD=27.7, to M=183.3, SD=26.1), showing a significant relationship, t(56)= 5.657, p<0.05. The relapse rate was not significantly different in the two groups. Conclusion The vocational consultation positively affects hope among drug dependents but did not affect their relapse rate during the six-month follow-up. Increasing the hope in these groups of patients may be effective in other aspects of treatment success in long-term follow-up. PMID:26955440

Drug markets in disadvantaged African American neighborhoods have altered social and sexual norms as well as sexual networks, which impact an individual’s risk of contracting a sexually transmitted infection. Presently, we describe the prevalence of sexual partnerships with males involved with illegal drugs among a sample of non-drug-dependent females. In 2010, 120 Black females aged 18 to 30 years completed a semistructured HIV-risk interview. Descriptive statistics revealed approximately 80% of females perceived neighborhood drug activity as a major problem, 58% had sex with a male drug dealer, 48% reported sex with a male incarcerated for selling drugs, and 56% believed drug dealers have the most sexual partners. Our results suggest sexual partnerships with males involved in the distribution of drugs are prevalent. These partnerships may play a substantial role in the spread of sexually transmitted infections among low-risk females, as drug dealers likely serve as a bridge between higher HIV-risk drug and prison populations and lower HIV-risk females. However, the significance of partnerships with males involved in drug dealing has received little attention in HIV and drug abuse literature. Presently, there is a need for more research focused on understanding the extent to which the drug epidemic affects the HIV risk of non-drug-dependent Black female residents of neighborhoods inundated with drugs. Special consideration should be given to the role of the neighborhood drug dealer in the spread of sexually transmitted infections. PMID:25797963
Role of opioid receptors in the reinstatement of opioid-seeking behavior: an overview.

Opioid abuse in humans is characterized by discontinuous periods of drug use and abstinence. With time, the probability of falling into renewed drug consumption becomes particularly high and constitutes a considerable problem in the management of heroin addicts. The major problem in the treatment of opioid dependence still remains the occurrence of relapse, to which stressful life events, renewed use of heroin, and exposure to drug-associated environmental cues are all positively correlated. To study the neurobiology of relapse, many research groups currently use the reinstatement animal model, which greatly contributed to disentangle the mechanisms underlying relapse to drug-seeking in laboratory animals. The use of this model is becoming increasingly popular worldwide, and new versions have been recently developed to better appreciate the differential contribution of each opioid receptor subtype to the relapse phenomenon. In this chapter we review the state of the art of our knowledge on the specific role of the opioid receptors as unrevealed by the reinstatement animal model of opioid-seeking behavior.

In Japan, methamphetamine (MAP) abuse has been a serious problem for 60 years, and many of MAP abusers have been incarcerated in prisons as a violator of the Stimulant Control Law in Japan. The purpose of the present study is to evaluate effectiveness of the relapse prevention guidance for drug-dependent inmates using a self-teaching workbook for drug-abusing adolescents and group therapy, conducted in the Harima Rehabilitation Program Center, one of the new prisons which the Ministry of Justice founded cooperating private enterprises as a "Private Finance Initiative" project. We provided for 89 male drug-dependent inmates, incarcerated in the Harima Rehabilitation Program Center, with the relapse prevention guidance consisting of a self-teaching workbook and group therapy, and implement pre-and post-evaluations by the Self-efficacy Scale for Drug Dependence (SES) and the Stages of Change Readiness and Treatment Eagerness Scale, 8th version for Drug Dependence (SOCRATES-8D). After a waiting term, the participants were provided with a self-teaching program, subsequently with a group program. At the point of completing the waiting term, no significant changes were observed in the SES and SOCRATES-8D scores. However, at the point of completing the self-teaching program, the SES scores significantly fell, while the total SOCRATES-8D score and the scores of the two subscales, the "Recognition" and "Ambivalence," significantly rose. Further, at the point of completing the group program, the total scores of the SES and SOCRATES-8D, and the score of the two SOCRATES-8D subscales, the "Recognition" and "Taking Steps," significantly rose. The relapse prevention guidance consisting of a self-teaching workbook and group therapy, conducted in the Harima Rehabilitation Program Center, were supposed to bring same internal changes as the "Stage of Changes" model, proposed by Prochaska and DiClemente, to drug-dependent inmates.
Inhibiting social support from massage-like stroking increases morphine dependence.

Our previous studies showed that altering solely the drug experience of the cage mates with which rodents are housed affects the development of morphine dependence. In this study, we used designer receptors exclusively activated by designer drugs to artificially increase or decrease the activity of peripheral dorsal root ganglia sensory neurons expressing the G-protein-coupled receptor MRGPRB4. This is because sensory MRGPRB4-expressing neurons were shown to specifically detect the sensation of massage-like stroking resulting from social grooming, which is an important affiliative social behavior in the rodent. Blocking the sensation of social grooming in morphine-treated mice housed with drug-naive mice (i.e. morphine cage mates) significantly increased the display of jumping behavior in morphine-withdrawn animals. Activating the sensation of social grooming in morphine-treated animals housed solely with other morphine-treated animals (i.e. morphine only) did not significantly alter the display of jumping behavior in morphine-withdrawn animals. Repetitive jumping behaviors have been shown to correlate with morphine dependence. Thus, this study showed a role of social grooming in the protective effect of being housed with drug-naive mice on the development of morphine dependence. It further confirms a role of social support in the development of substance use problems.

Four methods are proposed for modeling diffusion in heterogeneous media where diffusion and partition coefficients take on differing values in each subregion. The exercise was conducted to validate finite element modeling (FEM) procedures in anticipation of modeling drug diffusion with regional partitioning into ocular tissue, though the approach can be useful for other organs, or for modeling diffusion in laminate devices. Partitioning creates a discontinuous value in the dependent variable (concentration) at an intertissue boundary that is not easily handled by available general-purpose FEM codes, which allow for only one value at each node. The discontinuity is handled using a transformation on the dependent variable based upon the region-specific partition coefficient. Methods were evaluated by their ability to reproduce a known exact result, for the problem of the infinite composite medium (Crank, J. The Mathematics of Diffusion, 2nd ed. New York: Oxford University Press, 1975, pp. 38-39.). The most physically intuitive method is based upon the concept of chemical potential, which is continuous across an interphase boundary (method III). This method makes the equation of the dependent variable highly nonlinear. This can be linearized easily by a change of variables (method IV). Results are also given for a one-dimensional problem simulating bolus injection into the vitreous, predicting time disposition of drug in vitreous and retina.
Development of a novel osmotically driven drug delivery system for weakly basic drugs.
Guthmann, C; Lipp, R; Wagner, T; Kranz, H
2008-06-01
The drug substance SAG/ZK has a short biological half-life and because of its weakly basic nature a strong pH-dependent solubility was observed. The aim of this study was to develop a controlled release (cr) multiple unit pellet formulation for SAG/ZK with pH-independent drug release. Pellets with a drug load of 60% were prepared by extrusion/spheronization followed by cr-film coating with an extended release polyvinyl acetate/polyvinyl pyrrolidone dispersion (Kollidon SR 30 D). To overcome the problem of pH-dependent drug release the pellets were then coated with a second layer of an enteric methacrylic acid and ethyl acrylate copolymer (Kollicoat MAE 30 DP). To increase the drug release rates from the double layered cr-pellets different osmotically active ionic (sodium and potassium chloride) and nonionic (sucrose) additives were incorporated into the pellet core. Drug release studies were performed in media of different osmotic pressure to clarify the main release mechanism. Extended release coated pellets of SAG/ZK demonstrated pH-dependent drug release. Applying a second enteric coat on top of the extended release film coat failed in order to achieve pH-independent drug release. Already low enteric polymer levels on top of the extended release coated pellets decreased drug release rates at pH 1 drastically, thus resulting in a reversal of the pH-dependency (faster release at pH 6.8 than in 0.1N HCl). The addition of osmotically active ingredients (sodium and potassium chloride, and sucrose) increased the imbibing of aqueous fluids into the pellet cores thus providing a saturated drug solution inside the beads and increasing drug concentration gradients. In addition, for these pellets increased formation of pores and cracks in the polymer coating was observed. Hence drug release rates from double layered beads increased significantly. Therefore, pH-independent osmotically driven SAG/ZK release was achieved from pellets containing osmotically active ingredients and coated with an extended and enteric polymer. In contrast, with increasing osmotic pressure of the dissolution medium the in vitro drug release rates decreased significantly.
Insights from Preclinical Choice Models on Treating Drug Addiction
Banks, Matthew L.; Negus, S. Stevens
2016-01-01
Substance-use disorders are a global public health problem that arises from behavioral misallocation between drug use and more adaptive behaviors maintained by nondrug alternatives (e.g., food or money). Preclinical drug self-administration procedures that incorporate a concurrently available nondrug reinforcer (e.g., food) provide translationally relevant and distinct dependent measures of behavioral allocation (i.e., to assess the relative reinforcing efficacy of the drug) and behavioral rate (i.e., to assess motor competence). In particular, preclinical drug versus food ‘choice’ procedures have produced increasingly concordant results with both human laboratory drug self-administration studies and double-blind placebo-controlled clinical trials. Accordingly, here we provide a heuristic framework of substance-use disorders based on a behavioral-centric perspective and recent insights from these preclinical choice procedures. PMID:27916279

A growing literature suggests that excessive temporal discounting of delayed rewards may be a contributing factor in the etiology of substance abuse problems. Little is known, however, about how drug deprivation may affect temporal discounting of delayed rewards by drug-dependent individuals. To examine the extent to which opioid deprivation affects how opioid-dependent individuals discount small, medium and large quantities of delayed heroin and money. Thirteen opioid-dependent individuals maintained on buprenorphine completed a hypothetical choice task in which they choose between a constant delayed reward amount and an immediate reward amount that was adjusted until they expressed indifference between both outcomes. The task was completed for three values of heroin and money rewards during eight sessions under conditions of opioid deprivation (four sessions) and satiation (four sessions). Across conditions, hyperbolic functions provided a good fit for the discounting data. Degree of discounting was significantly higher when subjects were opioid deprived. Consistent with previous findings, degree of discounting was higher for heroin than money and inversely related to the magnitude of the reward. Opioid deprivation increased the degree to which dependent individuals discounted delayed heroin and money. Understanding the conditions that affect how drug-dependent individuals discount delayed rewards might help us understand the myopic choices made by such individuals and help improve treatment outcomes.

The diffusion equation should be solved for the non-steady-state problem of drug diffusion within a two-dimensional, biphasic stratum corneum membrane having homogeneous lipid and corneocyte phases. A numerical method was developed for a brick-and-mortar SC-geometry, enabling an explicit solution for time-dependent drug concentration within both phases. The lag time and permeability were calculated. It is shown how the barrier property of this model membrane depends on relative phase permeability, corneocyte alignment, and corneocyte-lipid partition coefficient. Additionally, the time-dependent drug concentration profiles within the membrane can be observed during the lag and steady-state phases. The model SC-membrane predicts, from purely morphological principles, lag times and permeabilities that are in good agreement with experimental values. The long lag times and very small permeabilities reported for human SC can only be predicted for a highly-staggered corneocyte geometry and corneocytes that are 1000 times less permeable than the lipid phase. Although the former conclusion is reasonable, the latter is questionable. The elongated, flattened corneocyte shape renders lag time and permeability insensitive to large changes in their alignment within the SC. Corneocyte/lipid partitioning is found to be fundamentally different to SC/donor partitioning, since increasing drug lipophilicity always reduces both lag time and permeability.

We reside in an era of technological innovation and advancement despite which infectious diseases like malaria remain to be one of the greatest threats to the humans. Mortality rate caused by malaria disease is a huge concern in the twenty-first century. Multiple drug resistance and nonspecific drug targeting of the most widely used drugs are the main reasons/drawbacks behind the failure in malarial therapy. Dose-related toxicity because of high doses is also a major concern. Therefore, to overcome these problems nano-based drug delivery systems are being developed to facilitate site-specific or target-based drug delivery and hence minimizing the development of resistance progress and dose-dependent toxicity issues. In this review, we discuss about the shortcomings in treating malaria and how nano-based drug delivery systems can help in curtailing the infectious disease malaria.

Children of substance abusing parents have an elevated risk for experiencing disruptions in household composition and for engaging in problem behaviors. This study investigated whether multiple parent figure transitions predicted the likelihood of delinquency and drug use among a sample of early adolescents with parents receiving methadone treatment for opiate addiction. Controlling for baseline delinquency, child characteristics, family conflict, parental depression, and parent criminal history, a greater number of parenting disruptions during the longitudinal study period was associated with a higher probability of delinquent behavior. Gender moderated the effect of parent figure transitions in a parallel analysis for drug use. After accounting for baseline drug use and potentially confounding factors, only adolescent females had a higher likelihood of drug use as the number of family disruptions increased. In contrast, age was strongly associated with drug use for males. A subgroup of youths who experienced tremendous family instability and had no single consistent parent figure during the study period were at extreme risk for delinquent behavior. The findings are interpreted in terms of cumulative stress resulting from multiple parenting disruptions over time and differential influences on the expression of problem behaviors depending on gender.

People with severe mental illness often have substantial problems with money mismanagement such as losing or lending money to other people and making impulsive or unnecessary purchases, including drugs and alcohol. Money mismanagement in turn affects patients' health and social functioning, and can lead to homelessness and other harm. This cross-sectional study evaluated demographic and clinical predictors of money mismanagement among SSI/SSDI recipients. SSI/SSDI beneficiaries ( N = 95) with recent cocaine use initiating a clinical trial were assessed at intake with demographic, cognitive, psychiatric, social/family, substance abuse, and financial measures. In multivariate regression analyses, psychiatric functioning and drug dependence diagnosis were independent predictors of self-reported money mismanagement. Even within individuals whom all had recently used cocaine, those with drug dependence and those with more psychiatric symptomatology had more difficulty managing their funds. Future studies might determine whether people who reduce their drug use and psychiatric symptomatology go on to better manage their funds.
Oral drug self-administration: an overview of laboratory animal studies.
Meisch, R A
2001-06-01
Many abused drugs can be established as orally delivered reinforcers for rhesus monkeys and other animals. Benzodiazepines, barbiturates, opioids, psychomotor stimulants, dissociative anesthetics, and ethanol can come to serve as reinforcers when taken by mouth. The principal problems in establishing drugs as reinforcers by the oral route of administration are (1) aversive taste, (2) delay in onset of central nervous system effects, and (3) consumption of low volumes of drug solution. Strategies have been devised to successfully overcome these problems, and orally delivered drugs can be established as effective reinforcers. Reinforcing actions are demonstrated by consumption of greater volumes of drug solution than volumes of the water vehicle, and supporting evidence for reinforcing effects consists of the maintenance of behavior under intermittent schedules of reinforcement and the generation of orderly dose-response functions. This article presents an overview of studies of behavior reinforced by oral drug reinforcement. Factors that control oral drug intake include dose, schedule of reinforcement, food restriction, and alternative reinforcers. Many drugs, administered by the experimenter, can alter oral drug reinforcement. Relative reinforcing effects can be assessed by choice procedures and by persistence of behavior across increases in schedule size. In general, reinforcing effects increase directly with dose. Rhesus monkeys prefer combinations of reinforcing drugs to the component drugs. The taste of drug solutions may act as a conditioned reinforcer and a discriminative stimulus. Consequences of drug intake include tolerance and physiological dependence. Findings with orally self-administered drugs are similar to many findings with other positive reinforcers, including intravenously self-administered drugs.
Prenatal cocaine exposure and neonatal/infant outcomes.
Cambell, Shelly
2003-01-01
Illegal drug use throughout the nation is a problem of epidemic proportion. Of particular concern is drug use among pregnant women. In most cases, these women have little hope of achieving a better life for themselves or their children. Illegal drugs, cocaine in particular, can have devastating effects on the neonate. These effects can last well into childhood and can exhibit themselves in academic, social, and family situations. Challenges for the neonatal nurse include early identification of these infants and use of available resources. This article addresses prenatal cocaine use and support services for drug-dependent women, effects of cocaine during the neonatal period, possible neonatal and infant outcomes, and implications for nursing practice.
The discovery of drug-induced illness.
Jick, H
1977-03-03
The increased use of drugs (and the concurrent increased risks of drug-induced illness) require definition of relevant research areas and strategy. For established marketed drugs, research needs depend on the magnitudes of risk of an illness from a drug and the base-line risk. With the drug risk high and the base-line risk low, the problem surfaces in premarketing studies or through the epidemic that develops after marketing. If the drug adds slightly to a high base-line risk, the effect is undetectable. When both risks are low, adverse effects can be discovered by chance, but systematic case-referent studies can speed discovery. If both risks are high, clinical trials and nonexperimental studies may be used. With both risks intermediate, systematic evaluations, especially case-referent studies are needed. Newly marketed drugs should be routinely evaluated through compulsory registration and follow-up study of the earliest users.

Fourteen million U.S. workers meet the diagnostic criteria for substance dependence, costing millions in lost productivity. Prior research suggests that employees who follow through with their Employee Assistance Program's (EAP) recommendations are more likely to participate and remain engaged in alcohol and other drug (AOD) treatment programs. This study identified rates of lifetime EAP service use for AOD problems and compared adults who reported using EAP services for AOD problems with those who used services other than EAP. Researchers analyzed a subset of participants from the National Epidemiologic Survey of Alcohol and Related Conditions who reported having received help for an AOD problem (NESARC, 2001-2002). Statistical analyses tested for differences in sociodemographic variables, lifetime mental health and substance abuse disorders, and health disability between EAP services users and users of other types of services. Among adults who sought services for AOD problems (n= 2,272), 7.58% (n= 166) reported using EAP services for these problems at some point during their lives. Major depressive disorder (lifetime), a drug use disorder (lifetime), and Black race/ethnicity were associated with a greater likelihood that someone would seek EAP services for help with their AOD problem. Results provide a foundation for researchers to understand who uses EAP services for AOD problems. Health and mental health professionals should increase their knowledge of EAP services to improve continuity of care for employees with AOD problems. EAPs are in a unique position to reach out to vulnerable employees in the workplace and engage them in treatment. Copyright © American Academy of Addiction Psychiatry.

to survey the most common and the most important drug-related problems in Lithuania, to explore their solution and factors influencing it, to formulate recommendations for solving drug-related problems. Pharmacists from community pharmacies participated in a random survey. They filled in questionnaires about drug-related problems and their solutions. It was the first survey on drug-related problems ever carried out in Lithuania. For the first time, it was found out that in Lithuania pharmacists most commonly encountered drug-related problem--additional drug therapy (52.03% of respondents)--and most rarely encountered drug-related problem--dosage too high (3% of respondents). Pharmacists stated that all categories of drug-related problems were of equal importance. It was established that pharmacists commonly solved drug-related problems associated with noncompliance with instructions (72.5% of respondents) and rarely met the problem when improper drug was selected (39.56% of respondents). Patients taking prescription medicines commonly encounter additional drug therapy problem, and patients taking nonprescription medications commonly encounter problems related to noncompliance with instructions.

Substance use among Korean adolescents has been increasing, but little is known about the correlates of substance use in this population. Identification of the correlates is required for development of preventive approaches that aim to reduce or eliminate risk. Therefore, we examined the prevalence and correlates of substance use including psychological problems in a nationwide sample of Korean adolescents. Data from the 2014 Korean Youth Risk Behavior Web-Based Survey, collected from 72,060 adolescents aged 12-18 years (mean age 14.94 ± 1.75 years), were analyzed. Participants' lifetime experiences with substances (alcohol, tobacco, and illicit drugs) were assessed. Participants' perceived stress, depressive mood, and suicidality during the previous 12 months were also investigated. The lifetime prevalence estimates of alcohol, tobacco, and illicit drug use were 43.0, 19.9, and 0.4 % of the participants, respectively. The most commonly used illicit drugs were inhalants. Older age, male gender, non-residence with family, low parental educational level and socio-economic status, and low academic achievement were positively and significantly associated with substance use. Substance (alcohol, tobacco, and illicit drug) use was positively and significantly associated with severe stress, depressive mood, and suicidality during the previous 12 months, with the highest odds ratios obtained from illicit drug use. These results indicate that the use of substances (alcohol, tobacco, and illicit drugs) among Korean adolescents is associated with socially disadvantaged families, psychological problems, and risky behavior. Health education including dependency prevention programs is needed for these high-risk groups.

Many recreational ecstasy/MDMA users display neuropsychobiological deficits, whereas others remain problem free. This review will investigate some of the drug and non-drug factors which influence the occurrence of these deficits. Acute and chronic MDMA usage are both important. Intensive use within a session is often associated with more problems. In term of lifetime usage, novice users generally remain unimpaired, whereas most heavy users report memory or other psychobiological problems which they attribute to ecstasy. These complaints are confirmed by objective deficits in working memory, attention, frontal-executive, and episodic memory tasks. Psychobiological deficits include disturbed sleep, sexual dysfunction, reduced immuno-competence, and increased oxidative stress. Further MDMA-related factors which may contribute to these changes, include acute and chronic tolerance, and drug dependence. Around 90ñ95% of ecstasy/MDMA users also take cannabis, and this can independently contribute to the adverse neuropsychobiological pro.les; although in some situations the acute co-use of these two drugs may be interactive rather than additive, since cannabis has relaxant and hypothermic properties. Alcohol, nicotine, amphetamine, and other drugs, can also affect the psychobiological pro.les of ecstasy polydrug users in complex ways. Pure MDMA users are rare but they have been shown to display significant neurocognitive deficits. Psychiatric aspects are debated in the context of the diathesis-stress model. Here the stressor of ecstasy polydrug drug use, interacts with various predisposition factors (genetic, neurochemical, personality), to determine the psychiatric outcome. Recreational MDMA is typically taken in hot and crowded dances/raves. Prolonged dancing, feeling hot, and raised body temperature, can also be associated with more psychobiological problems. This is consistent with the animal literature, where high ambient temperature and other metabolic stimulants boost the acute effects of MDMA, and cause greater serotonergic neurotoxicity. In conclusion, the neuropsychobiological effects of MDMA are modulated by a wide range of drug and non-drug factors. These multiple influences are integrated within a bioenergetic stress model, where factors which heighten acute metabolic distress lead to more neuropsychobiological problems.
Insights from Preclinical Choice Models on Treating Drug Addiction.
Banks, Matthew L; Negus, S Stevens
2017-02-01
Substance-use disorders are a global public health problem that arises from behavioral misallocation between drug use and more adaptive behaviors maintained by nondrug alternatives (e.g., food or money). Preclinical drug self-administration procedures that incorporate a concurrently available nondrug reinforcer (e.g., food) provide translationally relevant and distinct dependent measures of behavioral allocation (i.e., to assess the relative reinforcing efficacy of the drug) and behavioral rate (i.e., to assess motor competence). In particular, preclinical drug versus food 'choice' procedures have produced increasingly concordant results with both human laboratory drug self-administration studies and double-blind placebo-controlled clinical trials. Accordingly, here we provide a heuristic framework of substance-use disorders based on a behavioral-centric perspective and recent insights from these preclinical choice procedures.

[Mechanism of drug dependency: answers to the questions of KATO].
Takigawa, M
2000-01-01
The complicated mechanisms of drug dependency were discussed from the perspective of a reward, especially the perspective of psychic dependency of the brain. In Kato's article, the following questions were raised. (1) Improper usage of terminology in describing the objective pharmacological behavior and describing the subjective psychic experience, e.g. the term "obsessional comfort". (2) The enhanced effects of morphine and d-amphetamine in ICSS (intracranial self-stimulation) were not suitably regarded, as these might be the results of stimulus current running in the brain. The conclusion that "morphine and d-amphetamine are 2 kinds of addictive drugs due to the reinforcement effects on ICSS" appears to be putting the incidental before the fundamental because these are addictive drugs in clinical use. (3) It was unknown why the basic problem of drug dependency was limited to psychic stimulant (antihypnotic, etc.), and why only opiates were represented as an addictive drug. (4) The conclusion that the reinforcement effects of barbital and benzodiazepine were not observed in ICSS contradicted Kato's conclusion, in which the reinforcement effects were detected in an experiment involving self-administration. (5) He reiterated that the usage of terminology was confused in describing the psychic experience and pharmacological behavioral. In response to the comments of the editors, I would answer the questions as follows: It is well-known that the terminologies used in psychiatry are strict and prudent. This should also be the case in the description of pharmacological behaviors in animal models. The author admitted Kato's profound relevant experiences in drug dependency, and did not disapprove of his criticisms about the terminology used in the article to describe objective behaviors and observe subjective experience. That article was excerpted from one of my lectures, which to some extent allowed freedom in phrases and sentences. The following are my answers to Kato's questions.
Interpersonal problems across levels of the psychopathology hierarchy.
Girard, Jeffrey M; Wright, Aidan G C; Beeney, Joseph E; Lazarus, Sophie A; Scott, Lori N; Stepp, Stephanie D; Pilkonis, Paul A
2017-11-01
We examined the relationship between psychopathology and interpersonal problems in a sample of 825 clinical and community participants. Sixteen psychiatric diagnoses and five transdiagnostic dimensions were examined in relation to self-reported interpersonal problems. The structural summary method was used with the Inventory of Interpersonal Problems Circumplex Scales to examine interpersonal problem profiles for each diagnosis and dimension. We built a structural model of mental disorders including factors corresponding to detachment (avoidant personality, social phobia, major depression), internalizing (dependent personality, borderline personality, panic disorder, posttraumatic stress, major depression), disinhibition (antisocial personality, drug dependence, alcohol dependence, borderline personality), dominance (histrionic personality, narcissistic personality, paranoid personality), and compulsivity (obsessive-compulsive personality). All dimensions showed good interpersonal prototypicality (e.g., detachment was defined by a socially avoidant/nonassertive interpersonal profile) except for internalizing, which was diffusely associated with elevated interpersonal distress. The findings for individual disorders were largely consistent with the dimension that each disorder loaded on, with the exception of the internalizing and dominance disorders, which were interpersonally heterogeneous. These results replicate previous findings and provide novel insights into social dysfunction in psychopathology by wedding the power of hierarchical (i.e., dimensional) modeling and interpersonal circumplex assessment.

Solubility is concerned with solute and solvent to form a homogenous mixture. If solubility of a drug is low, then usually it is difficult to achieve desired therapeutic level of drug. Most of the newly developed entities have solubility problems and encounter difficulty in dissolution. Basic aim of solubility enhancement is to achieve desired therapeutic'level of drug to produce required pharmacological response. Different techniques are being used to enhance the solubility of water insoluble drugs. These techniques include particle size reduction, spray drying, kneading method, solvent evaporation method, salt formation, microemulsions, co-solven- cy, hydrosols, prodrug approach, supercritical fluid process, hydrogel micro particles etc. Selection of solubility improving method depends on drug properties, site of absorption, and required dosage form characteristics. Variety of polymers are also used to enhance solubility of these drugs like polyethylene glycol 300, polyvinyl pyrrolidone, chitosan, β-cyclodextrins etc.
Immunopharmacotherapy: vaccination strategies as a treatment for drug abuse and dependence.
Moreno, Amira Y; Janda, Kim D
2009-04-01
Despite intensive efforts for its eradication, addiction to both legal and illicit drugs continues to be a major worldwide medical and social problem. Drug addiction is defined as a disease state in which the body relies on a substance for normal functioning and develops physical dependence leading to compulsive and repetitive use despite negative consequences to the user's health, mental state or social life. Psychoactive substances such as cocaine, nicotine, alcohol, and amphetamines are able to cross the blood-brain barrier once ingested and temporarily alter the chemical balance of the brain. Current medications used for the treatment of dependence are typically agonists or antagonists of the drugs of abuse. The complex interrelations of the neuronal circuits have made it difficult to accurately predict the actions of potential agonist/antagonist drugs and have led to undesirable side effects within the central nervous system. Nearly forty years ago, a handful of groups began to explore the possibility of utilizing an individual's own immune machinery to counteract the effects of drug exposure in an approach later termed by our laboratory, immunopharmacotherapy.Immunopharmacotherapy aims to use highly specific antibodies to sequester the drug of interest while the latter is still in the bloodstream. Thus, creation of the antibody-drug complex will blunt crossing of the blood brain barrier (BBB) not only counteracting the reinforcing effects of the drug but also preventing any detrimental side effects on the CNS. In the present mini-review we aim to present a focused summary, including relevant challenges and future directions, of the current state of cocaine and nicotine vaccines as these two programs have been the most successful to date.

Levothyroxine (T4) is a narrow therapeutic index drug with classic bioequivalence problem between various available products. Dissolution of a drug is a crucial step in its oral absorption and bioavailability. The dissolution of T4 from three commercial solid oral dosage forms: Synthroid (SYN), generic levothyroxine sodium by Sandoz Inc. (GEN) and Tirosint (TIR) was studied using a sensitive ICP-MS assay. All the three products showed variable and pH-dependent dissolution behaviors. The absence of surfactant from the dissolution media decreased the percent T4 dissolved for all the three products by 26-95% (at 30 min). SYN dissolution showed the most pH dependency, whereas GEN and TIR showed the fastest and highest dissolution, respectively. TIR was the most consistent one, and was minimally affected by pH and/or by the presence of surfactant. Furthermore, dissolution of T4 decreased considerably with increase in the pH, which suggests a possible physical interaction in patients concurrently on T4 and gastric pH altering drugs, such as proton pump inhibitors. Variable dissolution of T4 products can, therefore, impact the oral absorption and bioavailability of T4 and may result in bioequivalence problems between various available products.
Pre-existence and emergence of drug resistance in a generalized model of intra-host viral dynamics.
Alexander, Helen K; Bonhoeffer, Sebastian
2012-12-01
Understanding the source of drug resistance emerging within a treated patient is an important problem, from both clinical and basic evolutionary perspectives. Resistant mutants may arise de novo either before or after treatment is initiated, with different implications for prevention. Here we investigate this problem in the context of chronic viral diseases, such as human immunodeficiency virus (HIV) and hepatitis B and C viruses (HBV and HCV). We present a unified model of viral population dynamics within a host, which can capture a variety of viral life cycles. This allows us to identify which results generalize across various viral diseases, and which are sensitive to the particular virus's life cycle. Accurate analytical approximations are derived that allow for a solid understanding of the parameter dependencies in the system. We find that the mutation-selection balance attained prior to treatment depends on the step at which mutations occur and the viral trait that incurs the cost of resistance. Life cycle effects and key parameters, including mutation rate, infected cell death rate, cost of resistance, and drug efficacy, play a role in determining when mutations arising during treatment are important relative to those pre-existing.

Maintenance of reinforcement to address the chronic nature of drug addiction
Silverman, Kenneth; DeFulio, Anthony; Sigurdsson, Sigurdur O.
2012-01-01
Background Drug addiction can be a chronic problem. Abstinence reinforcement can initiate drug abstinence, but as with other treatments many patients relapse after the intervention ends. Abstinence reinforcement can be maintained to promote long-term drug abstinence, but practical means of implementing long-term abstinence reinforcement are needed. Methods We reviewed 8 clinical trials conducted in Baltimore, MD from 1996 through 2010 that evaluated the therapeutic workplace as a vehicle for maintaining reinforcement for the treatment of drug addiction. The therapeutic workplace uses employment-based reinforcement in which employees must provide objective evidence of drug abstinence or medication adherence to work and earn wages. Results Employment-based reinforcement can initiate (3 of 4 studies) and maintain (2 studies) cocaine abstinence in methadone patients, although relapse can occur even after long-term exposure to abstinence reinforcement (1 study). Employment-based reinforcement can also promote abstinence from alcohol in homeless alcohol dependent adults (1 study), and maintain adherence to extended-release naltrexone in opioid dependent adults (2 studies). Conclusion Treatments should seek to promote life-long effects in patients. Therapeutic reinforcement may need to be maintained indefinitely to prevent relapse. Workplaces could be effective vehicles for the maintenance of therapeutic reinforcement contingencies for drug abstinence and adherence to addiction medications. PMID:22668883
Metabolic and redox barriers in the skin exposed to drugs and xenobiotics.
Korkina, Liudmila
2016-01-01
Growing exposure of human skin to environmental and occupational hazards, to numerous skin care/beauty products, and to topical drugs led to a biomedical concern regarding sustainability of cutaneous chemical defence that is essential for protection against intoxication. Since skin is the largest extra-hepatic drug/xenobiotic metabolising organ where redox-dependent metabolic pathways prevail, in this review, publications on metabolic processes leading to redox imbalance (oxidative stress) and its autocrine/endocrine impact to cutaneous drug/xenobiotic metabolism were scrutinised. Chemical and photo-chemical skin barriers contain metabolic and redox compartments: their protective and homeostatic functions. The review will examine the striking similarity of adaptive responses to exogenous chemical/photo-chemical stressors and endogenous toxins in cutaneous metabolic and redox system; the role(s) of xenobiotics/drugs and phase II enzymes in the endogenous antioxidant defence and maintenance of redox balance; redox regulation of interactions between metabolic and inflammatory responses in skin cells; skin diseases sharing metabolic and redox problems (contact dermatitis, lupus erythematosus, and vitiligo) Due to exceptional the redox dependence of cutaneous metabolic pathways and interaction of redox active metabolites/exogenous antioxidants with drug/xenobiotic metabolism, metabolic tests of topical xenobiotics/drugs should be combined with appropriate redox analyses and performed on 3D human skin models.
Naming, labeling, and packaging of pharmaceuticals.
Kenagy, J W; Stein, G C
2001-11-01
The problem of medical errors associated with the naming, labeling, and packaging of pharmaceuticals is discussed. Sound-alike and look-alike drug names and packages can lead pharmacists and nurses to unintended interchanges of drugs that can result in patient injury or death. The existing medication-use system is flawed because its safety depends on human perfection. Simplicity, standardization, differentiation, lack of duplication, and unambiguous communication are human factors concepts that are relevant to the medication-use process. These principles have often been ignored in drug naming, labeling, and packaging. Instead, current methods are based on long-standing commercial considerations and bureaucratic procedures. The process for naming a marketable drug is lengthy and complex and involves submission of a new chemical entity and patent application, generic naming, brand naming, FDA review, and final approval. Drug companies seek the fastest possible approval and may believe that the incremental benefit of human factors evaluation is small. "Trade dress" is the concept that underlies labeling and packaging issues for the drug industry. Drug companies are resistant to changing trade dress and brand names. Although a variety of private-sector organizations have called for reforms in drug naming, labeling, and packaging standards have been proposed, the problem remains. Drug names, labels, and packages are not selected and designed in accordance with human factors principles. FDA standards do not require application of these principles, the drug industry has struggled with change, and private-sector initiatives have had only limited success.

The treatment of methamphetamine dependence is a continuing global health problem. Agonist type pharmacotherapies have been used successfully to treat opioid and nicotine dependence and are being studied for the treatment of methamphetamine dependence. One potential candidate is lisdexamfetamine, a pro-drug for dexamphetamine, which has a longer lasting therapeutic action with a lowered abuse potential. The purpose of this study is to determine the safety of lisdexamfetamine in this population at doses higher than those currently approved for attention deficit hyperactivity disorder or binge eating disorder. This is a phase 2 dose escalation study of lisdexamfetamine for the treatment of methamphetamine dependence. Twenty individuals seeking treatment for methamphetamine dependence will be recruited at two Australian drug and alcohol services. All participants will undergo a single-blinded ascending-descending dose regime of 100 to 250 mg lisdexamfetamine, dispensed daily on site, over an 8-week period. Participants will be offered counselling as standard care. For the primary objectives the outcome variables will be adverse events monitoring, drug tolerability and regimen completion. Secondary outcomes will be changes in methamphetamine use, craving, withdrawal, severity of dependence, risk behaviour and other substance use. Medication acceptability, potential for non-prescription use, adherence and changes in neurocognition will also be measured. Determining the safety of lisdexamfetamine will enable further research to develop pharmacotherapies for the treatment of methamphetamine dependence.

New challenges and opportunities in managing substance abuse in Malaysia.
Mazlan, Mahmud; Schottenfeld, Richard S; Chawarski, Marek C
2006-09-01
Until recently, Malaysia has lagged behind in the treatment of drug addiction and related disorders, despite experiencing severe drug problems. By the end of 2004, 234,000 heroin users or heroin-dependent individuals had been registered in the official government registry, but other estimates exceed 500,000 for heroin abusers in the country. Amphetamine-type stimulant abuse is also increasing and of considerable public and government concern. Among the population of drug users, HIV and other infectious diseases rates are very high. In the Western Pacific regions, Malaysia has the second highest HIV prevalence (after Vietnam) among adult populations (0.62%) and the highest proportion of HIV cases resulting from injection drug use (76.3%). Drug use and related disorders exert a heavy burden on the country's health care and legal systems. Historically, drug abusers were rehabilitated involuntarily in correctional, rather than health-care, facilities. This primarily criminal treatment approach had limited effectiveness which led to widespread public dissatisfaction and the recent introduction of medical treatments for addiction. Naltrexone was introduced in 1999; buprenorphine was introduced in 2001 and methadone in 2003. Agonist maintenance programmes were embraced rapidly by the medical community in Malaysia. Currently, over 30,000 opiate-dependent patients are treated with agonist maintenance treatments by more than 500 medical practitioners in Malaysia. Despite these recent advances, treatments for amphetamine-type stimulant abuse or dependence are underdeveloped, and diversion of agonist medications is an emerging concern.

This study examined (a) changes in crystal methamphetamine use among regular ecstasy users (REU) in Australia and (b) associations of crystal use and smoking with demographics, drug use and harm. Cross-sectional surveys (2000-06) of REU in three Australian capital cities, and in 2006, 750 REU in all Australian capital cities. The interview included: demographics, drug use, risk behaviour, recent criminal activity and methamphetamine dependence using Severity of Dependence Scale. There was little change in overall methamphetamine use, but a marked increase in crystal methamphetamine smoking. Among recent methamphetamine users in 2006 (n = 606), crystal methamphetamine users (n = 364) reported more frequent methamphetamine use and higher levels of dependence. Compared with those who had used only other forms of methamphetamine, recent crystal methamphetamine users were more likely to 'binge' on drugs for > or = 48 hours, engage in crime and experience financial and legal problems related to drug use. Non-smoking crystal methamphetamine users (n = 78) more often reported recent injecting and heroin use. Recent smokers were more likely to have: greater polydrug use, recently overdosed on a 'party drug', and accessed medical services for their drug use. Many of these associations were accounted for by their injecting and heavier methamphetamine use, rather than smoking per se. Crystal methamphetamine smoking among REU has increased markedly and is associated with significant harm. This appears related to smokers' heavier levels of methamphetamine use. Effective harm reduction strategies should be tailored to these specific risks.
Development of immunopharmacotherapy against drugs of abuse.
Meijler, Michael M; Matsushita, Masayuki; Wirsching, Peter; Janda, Kim D
2004-01-01
Drug addiction is a major worldwide medical and social problem that continues to escalate. The addiction syndrome is remarkably similar between different drugs of abuse, and can be characterized as a chronic relapsing brain disorder with neurobiological changes that lead to a compulsion to take a drug with loss of control over drug intake. Presently used medications for the treatment of dependence disorders are based on drugs that are either agonists or antagonists of drugs of abuse, and have yielded only limited success. Immunopharmacotherapy is based on the generation or administration of antibodies that are capable of binding the targeted drug before it can reach the brain, whereas replacement strategies based on agonists or antagonists of these drugs generally cause many undesired side effects. A large amount of data has been gathered in recent years on the effects of active and passive immunization against cocaine, nicotine, PCP and methamphetamine in animal models, suggesting potential efficacy of these treatments in humans; and clinical trials are currently underway for vaccines against cocaine and nicotine.

A Systematic Tool to Reduce Inappropriate Prescribing (STRIP), which includes the Screening Tool to Alert doctors to Right Treatment (START) and the Screening Tool of Older Peoples' Prescriptions (STOPP), has recently been developed in the Netherlands for older patients with polypharmacy in the general population. Active involvement of the patient is part of this systematic multidisciplinary medication review. Although annual review of pharmacotherapy is recommended for people with an intellectual disability (ID), a specific tool for this population is not yet available. Besides, active involvement can be compromised by ID. Therefore, the objective of this observational pilot study was to evaluate the process of medication review using STRIP in adults with an ID living in a centralized or dependent setting and the identification of drug-related problems using this tool. The study was performed in three residential care organizations for ID. In each organization nine clients with polypharmacy were selected by an investigator (a physician in training to become a specialized physician for individuals with an ID) for a review using STRIP. Clients as well as their legal representatives (usually a family member) and professional caregivers were invited to participate. Reviews were performed by an investigator together with a pharmacist. First, to evaluate the process time-investments of the investigator and the pharmacist were described. Besides, the proportion of reviews in which a client and/or his legal representative participated was calculated as well as the proportion of professional caregivers that participated. Second, to evaluate the identification of drug-related problems using STRIP, the proportion of clients with at least one drug-related problem was calculated. Mean time investment was 130minutes for the investigator and 90minutes for the pharmacist. The client and/or a legal representatives were present during 25 of 27 reviews (93%). All 27 professional caregivers (100%) were involved. For every client included at least one drug-related problem was identified. In total 127 drug-related problems were detected, mainly potentially inappropriate or unnecessary drugs. After six months, 15.7% of the interventions were actually implemented. Medication review using STRIP seems feasible in adults with an ID and identifies drug-related problems. However, in this pilot study the implementation rate of suggested interventions was low. To improve the implementation rate, the treating physician should be involved in the review process. Besides, specific adaptations to STRIP to address drug-related problems specific for this population are required. Copyright © 2016 Elsevier Ltd. All rights reserved.

Hypnotic effects of melatonin and melatoninergic drugs are mediated via MT1 and MT2 receptors, especially those in the circadian pacemaker, the suprachiasmatic nucleus, which acts on the hypothalamic sleep switch. Therefore, they differ fundamentally from GABAergic hypnotics. Melatoninergic agonists primarily favor sleep initiation and reset the circadian clock to phases allowing persistent sleep, as required in circadian rhythm sleep disorders. A major obstacle for the use of melatonin to support sleep maintenance in primary insomnia results from its short half-life in the circulation. Solutions to this problem have been sought by developing prolonged-release formulations of the natural hormone, or melatoninergic drugs of longer half-life, such as ramelteon, tasimelteon and agomelatine. With all these drugs, improvements of sleep are statistically demonstrable, but remain limited, especially in primary chronic insomnia, so that GABAergic drugs may be indicated. Melatoninergic agonists do not cause next-day hangover and withdrawal effects, or dependence. They do not induce behavioral changes, as sometimes observed with z-drugs. Despite otherwise good tolerability, the use of melatoninergic drugs in children, adolescents, and during pregnancy has been a matter of concern, and should be avoided in autoimmune diseases and Parkinsonism. Problems and limits of melatoninergic hypnotics are compared. PMID:19557144

Quality of life must be one of the main purposes for the treatment of drug users, requiring a better understanding of the association between the quality of life and the severity of dependency. This study aimed to investigate the correlation between severity of substance use in various areas of human functioning and quality of life of illicit drug users in a psychosocial care center for alcohol and drugs. This cross-sectional study included 60 participants - illicit drug users - treated at a psychosocial care center for alcohol and drugs. Participants were evaluated with the short version of World Health Organization Quality of Life (WHOQOL-Bref) instrument to measure the quality of life, the 6th version of Addiction Severity Index (ASI-6) to assess the severity of dependence in several areas and the Mini International Neuropsychiatric Interview (MINI) to identify the presence of psychiatric disorders. Pearson and Spearman correlation tests and linear regression were applied to verify the association between the severity of dependence and the quality of life, and Student's t-test to compare the mean quality of life between individuals with and without psychiatric comorbidities. Negative correlation was found between the severity of dependence on the drugs dimensions: alcohol, psychiatric, medical, legal, family/social support and family/social problems of ASI-6, and the quality of life domains measured by the WHOQOL-Bref. The evidence was strongest in the psychiatric and medical dimensions. There was a significant difference in the quality of life mean among participants presenting or not presenting psychiatric comorbidities, for the psychological domain in anxiety disorders, and for the physical and psychological domains in mood disorders. The quality of life decreased as the severity of dependence increased, with different results in the various areas of the participant's life. This result emphasizes the need for training the professional team which works in the substance use disorders area for more comprehensive diagnostic evaluations and more appropriate therapeutic interventions for each area. The associations were more evident in the medical and psychiatric fields, indicating the need for greater attention to be paid in relation to medical and psychiatric comorbidities.
Racial disparity: substance dependency and psychological health problems among welfare recipients.
Lee, Kyoung Hag; Hines, Lisa D
2014-01-01
This study explored the racial disparity of substance dependency and psychological health among White, African American, and Hispanic Temporary Assistance to Needy Families (TANF) recipients as well as the relationship between substance dependency and psychological health. It analyzed 1,286 TANF recipients from the 2006 National Survey on Drug Use and Health data. Analysis of variance indicated that Whites were experiencing more nicotine and alcohol dependency and psychological distress than others, but African Americans and Hispanics were experiencing more cocaine dependency than Whites. Ordinary least squares regression revealed that nicotine dependency is significantly related to the psychological distress of Whites. Alcohol dependency is significantly associated with the psychological distress of three groups. Culturally competent programs are suggested.
Drug Solubility: Importance and Enhancement Techniques

Solubility, the phenomenon of dissolution of solute in solvent to give a homogenous system, is one of the important parameters to achieve desired concentration of drug in systemic circulation for desired (anticipated) pharmacological response. Low aqueous solubility is the major problem encountered with formulation development of new chemical entities as well as for the generic development. More than 40% NCEs (new chemical entities) developed in pharmaceutical industry are practically insoluble in water. Solubility is a major challenge for formulation scientist. Any drug to be absorbed must be present in the form of solution at the site of absorption. Various techniques are used for the enhancement of the solubility of poorly soluble drugs which include physical and chemical modifications of drug and other methods like particle size reduction, crystal engineering, salt formation, solid dispersion, use of surfactant, complexation, and so forth. Selection of solubility improving method depends on drug property, site of absorption, and required dosage form characteristics. PMID:22830056

This pre-post evaluation aimed to measure changes in knowledge and attitudes towards drug users among community representatives in Kabul, Afghanistan, over a period of expansion of harm reduction and drug dependence programming. A convenience sample of 160 professionals aged 18+ years completed interview questionnaires in 2007 and 2009. Views endorsing programme quality and the provision of condoms, infection counselling/testing and needle/syringe distribution increased significantly over the 2-year period. In 13 of 38 statements, there was a substantial (> 10%) change in agreement level, most commonly among men and medical professionals. Attitudes concerning support of drug users remained largely positive, with substantial attitude changes in some subgroups of the population. Further community education through the media and a more cohesive government drug policy may be needed to strengthen community support for harm reduction/drug treatment in Afghanistan.

To date, it has been difficult to address the issue of sexual functioning and drug use, and many approaches to it have basic problems and methodological errors. The present cross-sectional study compared the sexual functioning scores of a group of drug users with those of a group of nondrug users. It explored the relationship between drug abstinence and sexual functioning. A sample of 905 males participated in this study (549 met the substance dependence criteria and 356 were controls). All of them were assessed with the Changes in Sexual Functioning Questionnaire-Drugs version. The assessment was conducted from September 2009 to January 2011. The clinical sample was evaluated in nine different substance abuse treatment facilities. Results show that, overall, all dimensions (pleasure, desire, arousal, and orgasm) were moderately impaired. Yet, differences regarding preferred substance were observed. Pleasure and orgasm were the two areas most significantly impaired. In these areas, all drugs seemed to negatively affect sexual functioning. However, desire and arousal were not affected by all the substances. In addition, at least after 2 weeks of drug abstinence, no relationship was found between drug abstinence and improvement in sexual functioning. The sample studied had an average of 1 year of drug abstinence and was found to have poorer sexual functioning than the control group. Therefore, these results seem to contradict those that argue that drug use only impairs sexual functioning temporarily. Moreover, they suggest that sexual functioning does not improve just by stopping drug use. © 2012 International Society for Sexual Medicine.

Background and aims Relatively little is known about co-occurring gambling problems and their overlap with other addictive behaviors among individuals attending mental health services. We aimed to determine rates of gambling and substance use problems in patients accessing mental health services in Victoria, Australia. Methods A total of 837 adult patients were surveyed about their gambling and administered standardized screening tools for problem gambling and harmful tobacco, alcohol, and drug use. Prevalence of gambling problems was estimated and regression models used to determine predictors of problem gambling. Results The gambling participation rate was 41.6% [95% CI = 38.2-44.9]. The Problem Gambling Severity Index identified 19.7% [CI = 17.0-22.4] as "non-problem gamblers," 7.2% [CI = 5.4-8.9] as "low-risk" gamblers, 8.4% [CI = 6.5-10.2] as "moderate-risk" gamblers, and 6.3% [CI = 4.7-8.0] as "problem gamblers." One-fifth (21.9%) of the sample and 52.6% of all gamblers were identified as either low-risk, moderate-risk, or problem gamblers (PGs). Patients classified as problem and moderate-risk gamblers had significantly elevated rates of nicotine and illicit drug dependence (p < .001) according to short screening tools. Current diagnosis of drug use (OR = 4.31 [CI = 1.98-9.37]), borderline personality (OR = 2.59 [CI = 1.13-5.94]), bipolar affective (OR = 2.01 [CI = 1.07-3.80]), and psychotic (OR = 1.83 [CI = 1.03-3.25]) disorders were significant predictors of problem gambling. Discussion and conclusions Patients were less likely to gamble, but eight times as likely to be classified as PG, relative to Victoria's adult general population. Elevated rates of harmful substance use among moderate-risk and PG suggest overlapping vulnerability to addictive behaviors. These findings suggest mental health services should embed routine screening into clinical practice, and train clinicians in the management of problem gambling.
A longitudinal study of substance use and abuse in a single class of medical students.

A longitudinal study to ascertain the attitudes toward, and habits of, substance use among a single class of medical students. A single class from a northeastern medical school was surveyed in both its first year (February 1991, 176 students) and its third year (May 1993, 170 students). The students were asked to report how frequently during the prior year they had used drugs or alcohol, and whether their use of each substance had increased, decreased, or remained the same since entering medical school; to identify any family members with histories of alcohol or drug problems; and to report any incidence during the prior year of ten behaviors associated with substance dependence. The students were also asked to indicate their agreement or disagreement with 11 attitudinal statements. Additional attitudinal items asked the students to identify three major deterrents to the abuse of drugs and alcohol, and what they had done if they had become aware of a classmate with a drug or alcohol problem. Chi-square analysis and two-tailed t-tests were used to compare data from the two surveys. The response rates in the first and second surveys were 96.9% and 81.8%, respectively. Use of licit and illicit substances was comparable to that of chronological peers and prior national studies of medical trainees. Most of the students admitted to using alcohol at least once in the prior year (91.8% and 95%, respectively). In both years marijuana was the illicit drug used most often. Although there was a slight increase over time in the use of benzodiazepines (2.4% to 5.8%) and a decrease in the use of marijuana (29.4% to 21.7%), these changes were not significant. Few of the students in their third year reported using any substance other than alcohol more than once a month. In general, a greater percentage of the students reported a decrease rather than an increase in the use of a substance since entering medical school; the primary exception was for wine. As they progressed in their training, the students became less concerned about the effect of substance use on their performance and more likely to be embarrassed about admitting to an addiction. Although in each year a few of the students appeared to be at risk for substance dependence (8.9% and 3.5%, respectively), no student came to the attention of the administration because of problems related to substance use. While most of the students were unaware of any classmate who had a problem, half of those who were aware had done nothing, and the balance had rarely sought assistance from the faculty or administration. Although there was no evidence that substance use was a major problem, a few of the students appeared to be at risk for drug or alcohol dependence. Appropriate intervention, support, and referral systems should be identified for the few who may be at risk, and increased educational efforts are needed to help all students address this issue with their peers and, ultimately, with their patients.
Overlooked and underestimated? Problematic alcohol use in clients recovering from drug dependence.

Despite recognition of the harms related to alcohol misuse and its potential to interfere substantially with sustained recovery from drug dependency, research evaluating drug treatment outcomes has not addressed the issue comprehensively. It has been overlooked possibly because treatment research has been framed according to the primary drug of choice, rather than investigating the interactions between different combinations of drugs and/or alcohol use. This paper reports on a systematic review investigating whether concurrent alcohol use could impede recovery from illicit drug use in two potential ways: first, alcohol could become a substitute addiction and/or secondly, alcohol misuse post-treatment may place an individual at risk for relapse to their primary drug problem. A systematic search of four relevant databases was undertaken to identify peer-reviewed, quantitative drug treatment outcome studies that reported alcohol use pre-, post-treatment and follow-up. The search revealed 567 papers, of which 13 were assessed as fulfilling the key inclusion criteria.The review indicated inconsistent and therefore inconclusive support for the substitution hypothesis. However, the data revealed consistent support for the hypothesis that alcohol use increases relapse to drug use. (i) The potential negative impact of alcohol misuse on drug treatment outcomes remains under-researched and overlooked; (ii) alcohol consumption post-drug treatment may increase the likelihood that an individual will relapse to their primary drug; (ii) existing evidence regarding the substitution hypothesis is inconclusive, although there was an indication that a subgroup of participants will be vulnerable to alcohol becoming the primary addiction instead of drugs. We argue that future drug treatment outcome studies need to include detailed analysis of the influence of alcohol use pre- and post-drug treatment. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.

This paper examines rates of exposure to work-related violence and other trauma, and the prevalence of lifetime and current posttraumatic stress disorder (PTSD) among female street-based sex workers. It also investigates associations between current PTSD symptoms and: demographic characteristics, psychiatric comorbidity, injecting and sex risk behaviours, and trauma history. Cross sectional data collected from 72 women via face to face structured interviews. The interview included structured diagnostic assessment of DSM-IV PTSD; drug dependence; depression; experience of childhood trauma; and an assessment of sex working history. All but one of the women interviewed reported experiencing trauma, with the majority reporting multiple traumas that typically began in early childhood. Child sexual abuse, adult sexual assault and work related violence were commonly reported. Just under half of the women met DSM-IV criteria for PTSD and approximately one-third reported current PTSD symptoms. Adult sexual assault was associated with current PTSD symptoms. Depression and drug dependence were also highly prevalent; cocaine dependence in particular was associated with elevated rates of injecting risk and sexual risk behaviours. These women reported complex trauma histories and despite ongoing opportunities for clinical intervention, they continued to experience problems, suggesting that current models of treatment may not be appropriate. More targeted interventions, and integrated mental health and drug treatment services are needed to address the problems these women are experiencing. Outreach services to these women remain a priority. Education strategies to reduce risky injecting and sexual behaviours among sex workers should also remain a priority.
From clinical trial to prescription.
Carpenter, William T
2002-03-01
There are many steps between drug discovery and prescribing for a patient. Each step has problems. In this issue of ARCHIVES, Klein and colleagues propose changes in clinical trials that would result in more meaningful information for the treating physician. Of particular importance is the gap between what a physician needs to know and what is produced in the clinical trials that leads to approval of a new drug by the US Food and Drug Administration (FDA). Their recommendations for improving clinical trials are cogent, but broad-based implementation depends on an organizational structure and political effectiveness not presently in place. Most important, as the authors note, is an effective work group representing industry, regulatory agencies, and academic and federal science, addressing clinical trials issues with public participation. While improved quality and relevance of data from clinical trials will strengthen the scientific foundation of pharmacotherapy, other problems impede the delivery of objective information to the treating physician. Most hotly debated is the role of money in the creation and dissemination of knowledge.

Supply problems of drugs are an increasing and worldwide problem, also in Belgium. Hospital pharmacists try to manage drug supply problems to minimize the impact on patient care. This study aims to quantify in a detailed manner how much time employees of 17 Belgian hospital pharmacies spend on drug supply problems. During six months, employees of Belgian hospital pharmacies filled in the daily time spent on drug supply problems using a template containing all steps which can be executed to manage drug supply problems. Additionally, Belgian hospital pharmacists were asked to report the drugs which experienced drug supply problems together with the solution for this problem. Hospital pharmacists spent a median of 109 minutes a week on drug supply problems, with a minimum of 40 minutes per week and a maximum of 216 minutes per week. Fifty-nine percent of the total time spent on drug supply problems was executed by hospital pharmacists, 27% by pharmacy technicians; the rest was performed by logistic or administrative personnel. About one third of the total time spent was invested in gathering information on the supply problem. About two third of the supply disruptions caused drug shortages, meaning there was a need to switch to another (generic) therapeutic alternative. For most drug shortages, a Belgian generic medicine could be found. However in some cases, the alternative had to be ordered abroad or for some drug shortages, no alternative was available. These exploratory results on time spent by hospital pharmacists on drug supply problems in Belgium highlight the economic impact of drug supply problems for hospital pharmacies. A fully reliable, daily updated list on the federal agencies websites would be a major help to hospital pharmacists.

Multidrug resistance: prospects for clinical management.
Mansouri, A; Henle, K J; Nagle, W A
1992-01-01
Clinical success in the treatment of tumors with chemotherapy has significantly improved over the past several years. However, treatment failures due to drug resistance of cancer cells has remained a major problem. The classical form of multiple drug resistance is perhaps also the most common type of drug resistance, and represents the overexpression of a transmembrane glycoprotein pump (P-170) that mediates the efflux of a spectrum of structurally and functionally unrelated drugs. Here, we discuss recent evidence that support the concept that the total phenomenon of multiple drug resistance (MDR) involves several other mechanisms in addition to that underlying "classical" MDR. These include the action of other energy-dependent membrane efflux pumps, elevated levels of GSH for drug conjugation and detoxification to facilitate export, enhanced DNA repair facility, gene amplification and oncogene activation. The combination of mechanisms used by any particular cell line is variable and suggests that many of these mechanisms are independent. Successful reversal of drug resistance appears to require the identification of relevant operative resistance mechanisms. An example is the competitive inhibition of P-170 with verapamil, quinine and tamoxifen. A broadly successful strategy for killing drug-resistant cancer cells, however, could be based on either selective energy depletion of cancer cells or the permeabilization of tumor cells with an effective bypass of efflux pumps, since many mechanisms of drug resistance entail the energy-dependent export of toxins. The latter approach may be achieved via membrane lipid modifications or the introduction of membrane pores by biological or physical (electroporation) means.

Randomized trial of intensive motivational interviewing for methamphetamine dependence.
Polcin, Douglas L; Bond, Jason; Korcha, Rachael; Nayak, Madhabika B; Galloway, Gantt P; Evans, Kristy
2014-01-01
An intensive, 9-session motivational interviewing (IMI) intervention was assessed using a randomized clinical trial of 217 methamphetamine (MA) dependent individuals. Intensive motivational interviewing (IMI) was compared with a single standard session of MI (SMI) combined with eight nutrition education sessions. Interventions were delivered weekly over 2 months. All study participants also received standard outpatient group treatment three times per week. Both study groups showed significant decreases in MA use and Addiction Severity Index drug scores, but there were no significant differences between the two groups. However, reductions in Addiction Severity Index psychiatric severity scores and days of psychiatric problems during the past 30 days were found for clients in the IMI group but not the SMI group. SMI may be equally beneficial to IMI in reducing MA use and problem severity, but IMI may help alleviate co-occurring psychiatric problems that are unaffected by shorter MI interventions. Additional studies are needed to assess the problems, populations, and contexts for which IMI is effective.

Substance use disorder is characterized by impaired decision making, impulsivity, and risk taking. Pathological gambling shares many of these characteristics, and having both diagnoses may be associated with greater problems than either diagnosis alone. We investigated whether among substance-dependent individuals, comorbid pathological gambling would be associated with worse decision making, greater impulsivity, risk taking, and drug severity. Ninety-six substance-dependent individuals were recruited from a residential treatment program and divided into 1 of the 2 groups depending on whether they met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria for pathological gambling (SDPG, n = 26) or not (SD, n = 70). Ninety-two controls were recruited from the community. Participants completed a decision-making task (modified Iowa Gambling Task), measures of impulsivity (Barratt Impulsivity Scale and Delay Discounting), and risk taking (Balloon Analog Risk Task). Decision making was analyzed using a computational model. We tested for group differences using analysis of covariance or Kruskal-Wallis and appropriate post-hoc tests. The groups differed in decision-making parameters (P < 0.001) and self-reported impulsivity (P < 0.001). All post-hoc comparisons were significant on these measures, and indicated stepwise changes in controls, followed by SD, followed by SDPG, with SDPG performing worse on decision making and being more impulsive. Compared with SD, SDPG had greater drug severity (P < 0.001). No group differences were observed in delay discounting or risk taking. Compared with individuals with substance dependence without pathological gambling, those with both disorders demonstrated worse decision making and significantly more drug-related symptoms. When evaluating patients with substance dependence, clinicians should consider diagnostic assessments for gambling, as the co-occurrence of both disorders may impact clinical characteristics.

There are complex historical connections between sexual minoritisation and desires to chemically alter bodily experience. For gay men, drug and alcohol use can be a creative or experimental response to social marginalisation - and not necessarily a problematic one in every instance. Numerous studies have found that infection with HIV and other sexually transmissible infections (STIs) is more likely among gay and men who have sex with men (MSM) who use recreational drugs than those who do not, but the causal nature of these relations is uncertain. Sexualised drug use is associated with a range of other problems, including dependence, mental health issues, accident and overdose. A growing body of work in the Alcohol and Other Drugs (AOD) field demonstrates the action of drugs and their purported effects to be a product of their relations with various other actors, contexts and practices. Given these contingencies, it is impossible to predict the future of drugs or their effect on the sexual health of gay and MSM with any degree of certainty. This article outlines some of the conditions most likely to mediate such futures in the medium term. Public funding for lesbian, gay, bisexual, transgender and queer drug issues should not remain restricted to questions of HIV prevention and sexual health. It should be expanded to equip sexual health and AOD service providers with the cultural and sexual literacy to mitigate stigma and allow them to respond constructively to drug problems among sexual and gender minorities as a matter of priority.
Perchance to Dream: Pathology, Pharmacology, and Politics in a 24-Hour Economy.
Brassington, Iain
2018-04-01
The lack of sleep is a significant problem in the modern world. The structure of the economy means that 24 hour working is required from some of us, sometimes because we are expected to be able to respond to share-price fluctuations on the other side of the planet, sometimes because we are expected to serve kebabs to people leaving nightclubs, and sometimes because lives depend on it. The immediate effect is that we feel groggy; but there may be much more sinister long-term effects of persistent sleep deprivation and disruption, the evidence for which is significant, and worth taking seriously. If sleeplessness has a serious impact on health, it represents a notable public health problem. In this article, I sketch that problem, and look at how exploiting the pharmacopoeia (or a possible future pharmacopoeia) might allow us to tackle it. I also suggest that using drugs to mitigate or militate against sleeplessness is potentially morally and politically fraught, with implications for social justice. Hence, whatever reasons we have to use drugs to deal with the problems of sleeplessness, we ought to be careful.
Kratom (Mitragyna speciosa) dependence, withdrawal symptoms and craving in regular users.
Singh, Darshan; Müller, Christian P; Vicknasingam, Balasingam K
2014-06-01
Kratom (Mitragyna speciosa) preparations have been traditionally used in Southeast Asia for its medicinal properties. Lately, Kratom use has spread to Europe and the US, where abuse potential and health hazards increasingly emerge. This study is the first to measure systematically Kratom dependence, withdrawal symptoms, and drug craving in regular Kratom users in Malaysia. A cross-sectional survey of 293 regular Kratom users was conducted in the community across three northern peninsular states of Malaysia. The Leeds Dependence Questionnaire, Marijuana Withdrawal Checklist, and Marijuana Craving Questionnaire-Short Form were used to measure Kratom dependence, withdrawal and craving. More than half of the regular users (>6 month of use) developed severe Kratom dependence problems, while 45% showed a moderate Kratom dependence. Physical withdrawal symptoms commonly experienced include muscle spasms and pain, sleeping difficulty, watery eyes/nose, hot flashes, fever, decreased appetite, and diarrhoea. Psychological withdrawal symptoms commonly reported were restlessness, tension, anger, sadness, and nervousness. The average amount of the psychoactive compound, mitragynine, in a single dose of a Kratom drink was 79mg, suggesting an average daily intake of 276.5mg. Regular users who consumed ≥3 glasses Kratom per day, had higher odds of developing severe Kratom dependence, withdrawal symptoms, and inability to control Kratom craving. The findings from this study show that regular Kratom use is associated with drug dependency, development of withdrawal symptoms, and craving. These symptoms become more severe with prolonged use and suggest a stronger control of the drug. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Tuberculosis has proved harmful to the entire history of mankind from past several decades. Decaprenyl-phosphoryl-ribose 2'-epimerase (DprE1) is a recent target which was identified in 2009 but unfortunately it is neither explored nor crossed phase II. In past several decades few targets were identified for effective antitubercular drug discovery. Resistance is the major problem for effective antitubercular drug discovery. Arabinose is constituent of mycobacterium cell wall. Biosynthesis of arabinose is FAD dependant two step epimerisation reaction which is catalysed by DprE1 and DprE2 flavoprotein enzymes. The current review is mainly emphases on DprE1 as a perspective challenge for further research.
A potential role for N-acetylcysteine in the management of methamphetamine dependence.
McKetin, Rebecca; Dean, Olivia M; Baker, Amanda L; Carter, Greg; Turner, Alyna; Kelly, Peter J; Berk, Michael
2017-03-01
Methamphetamine dependence is a growing problem in Australia and globally. Currently, there are no approved pharmacotherapy options for the management of methamphetamine dependence. N-acetylcysteine is one potential pharmacotherapy option. It has received growing attention as a therapy for managing addictions because of its capacity to restore homeostasis to brain glutamate systems disrupted in addiction and thereby reduce craving and the risk of relapse. N-acetylcysteine also has antioxidant properties that protect against methamphetamine-induced toxicity and it may therefore assist in the management of the neuropsychiatric and neurocognitive effects of methamphetamine. This commentary overviews the actions of N-acetylcysteine and evidence for its efficacy in treating addiction with a particular focus on its potential utility for methamphetamine dependence. We conclude that the preliminary evidence indicates a need for full-scale trials to definitively establish whether N-acetylcysteine has a therapeutic benefit and the nature of this benefit, for managing methamphetamine dependence.

Many patients with serious mental illness are addicted to drugs and alcohol. This comorbidity creates additional problems for the patients and for the clinicians, health care systems, and social-service agencies that provide services to this population. One problem is that disability income, which many people with serious mental illness receive to pay for basic needs, may facilitate drug abuse. In this study, we assessed the temporal patterns of cocaine use, psychiatric symptoms, and psychiatric hospitalization in a sample of schizophrenic patients receiving disability income. We evaluated 105 male patients with schizophrenia and cocaine dependence at the time of their admission to the hospital. They had severe mental illness and a long-term dependence on cocaine, with repeated admissions to psychiatric hospitals; many were homeless. The severity of psychiatric symptoms and urinary concentrations of the cocaine metabolite benzoylecgonine were evaluated weekly for 15 weeks. Cocaine use, psychiatric symptoms, and hospital admissions all peaked during the first week of the month, shortly after the arrival of the disability payment, on the first day. The average patient spent nearly half his total income on illegal drugs. Among cocaine-abusing schizophrenic persons, the cyclic pattern of drug use strongly suggests that it is influenced by the monthly receipt of disability payments. The consequences of this cycle include the depletion of funds needed for housing and food, exacerbation of psychiatric symptoms, more frequent psychiatric hospitalization, and a high rate of homelessness. The troubling irony is that income intended to compensate for the disabling effects of severe mental illness may have the opposite effect.
Drug-Induced Liver Injury: Advances in Mechanistic Understanding that will Inform Risk Management
Mosedale, Merrie; Watkins, Paul B.
2016-01-01
Drug-induced liver injury (DILI) is a major public health problem. Intrinsic (dose-dependent) DILI associated with acetaminophen overdose is the number one cause of acute liver failure in the US. However the most problematic type of DILI impacting drug development is idiosyncratic, occurring only very rarely among treated patients and often only after several weeks or months of treatment with the offending drug. Recent advances in our understanding of the pathogenesis of DILI suggest that three mechanisms may underlie most hepatocyte effects in response to both intrinsic and idiosyncratic DILI drugs: mitochondrial dysfunction, oxidative stress, and alterations in bile acid homeostasis. However, in some cases, hepatocyte stress promotes an immune response that results in clinically important idiosyncratic DILI. This review discusses recent advances in our understanding of the pathogenesis of both intrinsic and idiosyncratic DILI as well as emerging tools and techniques that will likely improve DILI risk identification and management.

Calculating the social cost of illegal drugs: a theoretical approach.
Diomidous, Marianna; Zimeras, Stelios; Mechili, Aggelos
2013-01-01
The use of illegal drugs generates a wide range of social harms depending on various ways, according to the policy definition of the problem. The challenge is the way to model the impact of illegal drugs use during a long time period considering the factors that affects the process. Based on these models, estimation could be measured and prediction could be achieved. The illegal drugs use might affect the economic and social structure of the public system leading to direct and effective decisions to overcome the problematic. For that reason, calculation of social cost related to the use of illegal could be introduced over time (t) as a proposed social measure to define the variability of social indicator on society. In this work, a theoretical approach for the calculation of social cost of illegal drugs is proposed and models over time are defined.
Using behavioral economics to predict opioid use during prescription opioid dependence treatment.
Worley, Matthew J; Shoptaw, Steven J; Bickel, Warren K; Ling, Walter
2015-03-01
Research grounded in behavioral economics has previously linked addictive behavior to disrupted decision-making and reward-processing, but these principles have not been examined in prescription opioid addiction, which is currently a major public health problem. This study examined whether pre-treatment drug reinforcement value predicted opioid use during outpatient treatment of prescription opioid addiction. Secondary analyses examined participants with prescription opioid dependence who received 12 weeks of buprenorphine-naloxone and counseling in a multi-site clinical trial (N=353). Baseline measures assessed opioid source and indices of drug reinforcement value, including the total amount and proportion of income spent on drugs. Weekly urine drug screens measured opioid use. Obtaining opioids from doctors was associated with lower pre-treatment drug spending, while obtaining opioids from dealers/patients was associated with greater spending. Controlling for demographics, opioid use history, and opioid source frequency, patients who spent a greater total amount (OR=1.30, p<.001) and a greater proportion of their income on drugs (OR=1.31, p<.001) were more likely to use opioids during treatment. Individual differences in drug reinforcement value, as indicated by pre-treatment allocation of economic resources to drugs, reflects propensity for continued opioid use during treatment among individuals with prescription opioid addiction. Future studies should examine disrupted decision-making and reward-processing in prescription opioid users more directly and test whether reinforcer pathology can be remediated in this population.

Background Research grounded in behavioral economics has previously linked addictive behavior to disrupted decision-making and reward-processing, but these principles have not been examined in prescription opioid addiction, which is currently a major public health problem. This study examined whether pre-treatment drug reinforcement value predicted opioid use during outpatient treatment of prescription opioid addiction. Methods Secondary analyses examined participants with prescription opioid dependence who received 12 weeks of buprenorphine-naloxone and counseling in a multi-site clinical trial (N = 353). Baseline measures assessed opioid source and indices of drug reinforcement value, including the total amount and proportion of income spent on drugs. Weekly urine drug screens measured opioid use. Results Obtaining opioids from doctors was associated with lower pre-treatment drug spending, while obtaining opioids from dealers/patients was associated with greater spending. Controlling for demographics, opioid use history, and opioid source frequency, patients who spent a greater total amount (OR = 1.30, p < .001) and a greater proportion of their income on drugs (OR = 1.31, p < .001) were more likely to use opioids during treatment. Conclusions Individual differences in drug reinforcement value, as indicated by pre-treatment allocation of economic resources to drugs, reflects propensity for continued opioid use during treatment among individuals with prescription opioid addiction. Future studies should examine disrupted decision-making and reward-processing in prescription opioid users more directly and test whether reinforcer pathology can be remediated in this population.

Drug policy in China. Transformations, current status and future prospects.
Liu, X; Li, S
1997-07-01
The pharmaceutical sector in China developed rapidly with the implementation of the market-oriented economic reforms, which began at the end of the 1970s. From 1980 to 1988 the production of drugs quadrupled, subsequently increasing at an annual rate of 20%, and consumption of drugs correspondingly increased. The increase in drug production was largely a result of the increase in the number of pharmaceutical companies, particularly the number of private joint ventures, of which there were none in 1980 and 1900 in 1994, accounting for 37% of the total number of pharmaceutical companies. With the transformation of the Chinese pharmaceutical market, some new problems have appeared. The low efficiency of pharmaceutical companies, poor-quality drugs, unfair competition and misuse of drugs have been of great concern to the Chinese government. Some countermeasures have been taken, but the problems remain. Increases in the age of the Chinese population, increases in income and changes in disease patterns, together with membership of the World Trade Organization will promote the development of the pharmaceutical market. However, health-insurance reform, an essential drug list, the separation of drugs from services, and controls on the increases in hospital revenue will reduce the demand for drugs. Pharmaceutical companies in China face both opportunities and challenges. The trend in development of the pharmaceutical market depends on the outcome of the interaction between the factors that increase, and those that decrease, the demand for drugs. While the general trend is towards an increase in the demand for drugs and the expansion of the pharmaceutical market, downward fluctuation is inevitable if effective health reforms of cost control are introduced nationwide.

We assessed the prevalence and characteristics of prescription drug misuse among youth ages 15-25 to examine differences by student and employment status, and associations with workplace antidrug policies and programs. Multivariate logistic regressions analyzed associations in weighted data on the 20,457 young adults in the combined 2004-2008 National Surveys on Drug Use and Health. Demographic controls included sex, race, community size, and age group. After we accounted for demographic controls, at ages 15-25, students were less likely than nonstudents to misuse prescription drugs. Segmenting student from nonstudent groups, working consistently was associated with a further reduction in misuse for those ages 18-25. When we controlled for demographics and substance use history, both Employee Assistance Program (EAP) services and awareness that one's employer had a drug-free workplace policy were associated with significantly lower misuse of prescription drugs (OR = 0.85 for each program, 95% CI [0.73, 1.00] and [0.72, 1.00]). Associations of workplace antidrug policies and programs with marijuana use and with Diagnostic and Statistical Manual for Mental Disorders, Fourth Edition, criteria for alcohol abuse and dependence contrasted sharply with these patterns. All four aspects were significantly associated with lower marijuana use. None was associated with problem drinking. Protective effects of drug-free workplace policy and EAPs persist after other substance use was controlled for. Comparing the effects of workplace programs on illicit drug use and problem drinking versus prescription misuse suggests that those protective associations do not result from selection bias. Thus, drug-free workplace policies and EAPs appear to help protect younger workers against prescription misuse. If workplace substance use disorder programs focused prevention messages and interventions on prescription drug misuse, their impact on misuse might increase.

To analyze the association between drug (DAD) and alcohol (AAD) abuse and dependency and criminal and clinical background by gender of prisoners in São Paulo, Brazil. Cross-sectional study, random sample stratified by administrative district, from which prisons and prisoners were selected via random, multistage sampling. Psychiatric diagnoses were made with the CIDI 2.1. Lifetime prevalence and 95% CI were calculated and adjusted via analysis of complex samples. Multinomial logistic regression analysis was carried out with four categories of dependent variables: presence AAD; presence DAD; presence of another mental disorder; no mental disorders. For female alcohol and drug abuse and dependency (ADAD) were combined into a single category. The sample was composed by 1809 interviewed prisoners (1192 men and 617 women). Prevalence of DAD and AAD was 25.2% and 15.6%, respectively, among female prisoners, and 26.5% and 18.5% among males. Male prisoners with DAD were more likely to have a criminal record as an adolescent (OR 2.17), to be a repeat offender (OR 2.85), and to have committed a property crime (OR 2.18). Prisoners with AAD were repeat offenders (OR 2.18). Among female prisoners, ADAD was associated with repeat offenses (OR 3.39), a criminal record as an adolescent (OR 9.24), a clinical or infectious condition (OR 5.09), another health problem (OR 3.04), and violent crime (OR 2.5). The study confirmed an association between drug-use disorders and the criminal and clinical background in the study population. Prisoners with such disorders were more likely to be repeat offenders and to have a criminal record as adolescents. Among female prisoners disorders were also associated with violent crime and health problems, while among males they were associated with property crime. These patterns in clinical and criminal backgrounds illustrate the need for social rehabilitation programs and specific medical treatment for prison populations.

Previous research has indicated that non-dependent polydrug users are willing to pay more money to buy good quality drugs as their income increased. This study sought to examine whether altering the perceived quality of controlled drugs would affect drug purchases if the monetary price remained fixed. A random sample of 80 polydrug users were recruited. All participants were administered an anonymous questionnaire consisting of the Drug Abuse Screening Test for Adolescents (DAST-A), the Severity of Dependence Scale for cannabis (SDS), the Alcohol Use Disorders Identification Test (AUDIT), the Hospital Anxiety and Depression Scale (HADS), and questions about their drug use. Participants then completed a simulation of controlled drug purchases where the price of alcohol, amphetamine, cannabis, cocaine, and ecstasy remained the same but their perceived quality changed (i.e. unit price increased as the perceived quality decreased). The demand for alcohol was quality inelastic and alcohol quality had no effects on the purchase of any other controlled drug. Demand for cannabis was quality elastic and alcohol substituted for cannabis as its unit price increased. Demand for cocaine was quality elastic and alcohol, cannabis, and ecstasy substituted for cocaine as its unit price increased. Demand for ecstasy was quality elastic and alcohol and cocaine both substituted for ecstasy as its unit price increased. These results suggest that perceived quality influences the demand for controlled drugs and that monitoring the perceived quality of controlled drugs may provide a warning of potential public health problems in the near future.
Circumstances and toxicology of sudden or unnatural deaths involving alprazolam.
Darke, Shane; Torok, Michelle; Duflou, Johan
2014-05-01
There has been a great deal of clinical concern regarding alprazolam abuse. This paper reported on alprazolam positive cases of sudden or unnatural deaths presenting to the New South Wales Department of Forensic Medicine (DOFM), 1/1/1997-31/12/2012. Case series. 412 cases were identified. There was a large increase in the annual number of cases, from 3 in 1997 to 86 in 2012. By 2012, 4.5% of all DOFM case presentations involved alprazolam. The mean age was 41.3 years, and 66.5% were male. Circumstances of death were: accidental drug toxicity (57.0%), deliberate drug toxicity (10.4%), suicide by means other than drug overdose (12.6%), disease (10.0%), accident (5.1%), homicide (2.4%). The major factor driving the increase in cases was accidental drug toxicity involving alprazolam, rising from 0 in 1997 to 58 in 2012. A history of drug/alcohol problems was noted in 80.4%, and 56.6% were injecting drug users. The median alprazolam concentration was 0.08 mg/L (range 0.005-2.10mg/L), with 37.4% of cases having concentrations of ≥ 0.1 mg/L. In 94.9% of cases, drugs other than alprazolam and its metabolites were present, including all accidental overdoses. The most commonly detected drugs were opioids (64.6%), other benzodiazepines (44.4%) and alcohol (34.5%). A third (31.8%) of cases were HCV positive. Cases involving alprazolam increased markedly, driven mostly by toxicity deaths amongst people with known drug and alcohol problems. Caution in prescribing alprazolam would appear appropriate, particularly to those with known drug dependence. Copyright © 2014. Published by Elsevier Ireland Ltd.
IMPLEMENTATION OF DRUG ADDICTS RIGHT TO HEALTH PROTECTION (SEPARATE ASPECTS).
Shevchuk, O; Rzhevska, O; Korop, O; Pyliuha, L
2018-03-01
The purpose of the research is to analyze specific problems of the realization of the right to protect the health of people who take narcotic drugs or psychotropic substances. To achieve this goal, statistics have been analyzed on the number of people using narcotic drugs or psychotropic substances (including drug-addicted children) placed on medical records and the number of their applications for medical care. It has been found out that people in this category often face a denial of medical care that causes extremely strong physical and mental suffering. The analysis of the understanding of the legal design of the «right to health care» in the scientific literature, national legislation and international legal documents was made. State institutions and local authorities providing «the right to health care» of people taking narcotic or psychotropic drugs are singled out. The absence of grounds for restricting the right to protect the health of people who take narcotic or psychotropic drugs who are not registered is justified. In the course of the research, it was found out that people who take narcotic drugs or psychotropic substances are more likely than other patients to need medical assistance and, when requesting the right to health care, face a number of problems that require immediate solution: incomplete provision of quality free medical care; unimplementation of rehabilitation programs for such categories of patients; the lack of the right of children who take narcotic drugs or psychotropic substances to make their own decisions at the age of 14 and apply to public health institutions for the treatment of drug addiction; violations of the continuity of SMT programs and their absence in penal institutions for drug dependent people. It was proposed to introduce a number of changes in the relevant normative legal acts.
The tongue and its control by sleep state-dependent modulators.
Horner, R L
2011-12-01
The neural networks controlling vital functions such as breathing are embedded in the brain, the neural and chemical environment of which changes with state, i.e., wakefulness, non-rapid eye movement (non-REM) sleep and REM sleep, and with commonly administered drugs such as anaesthetics, sedatives and ethanol. One particular output from the state-dependent chemical brain is the focus of attention in this paper; the motor output to the muscles of the tongue, specifically the actions of state-dependent modulators acting at the hypoglossal motor pool. Determining the mechanisms underlying the modulation of the hypoglossal motor output during sleep is relevant to understanding the spectrum of increased upper airway resistance, airflow limitation, hypoventilation and airway obstructions that occur during natural and drug-influenced sleep in humans. Understanding the mechanisms underlying upper airway dysfunction in sleep-disordered breathing is also important given the large and growing prevalence of obstructive sleep apnea syndrome which constitutes a major public health problem with serious clinical, social and economic consequences.
Caffeinated Energy Drinks -- A Growing Problem
Reissig, Chad J.; Strain, Eric C.; Griffiths, Roland R.
2009-01-01
Since the introduction of Red Bull in Austria in 1987 and in the United States in 1997, the energy drink market has grown exponentially. Hundreds of different brands are now marketed, with caffeine content ranging from a modest 50 mg to an alarming 505 mg per can or bottle. Regulation of energy drinks, including content labeling and health warnings differs across countries, with some of the most lax regulatory requirements in the U.S. The absence of regulatory oversight has resulted in aggressive marketing of energy drinks, targeted primarily toward young males, for psychoactive, performance-enhancing and stimulant drug effects. There are increasing reports of caffeine intoxication from energy drinks, and it seems likely that problems with caffeine dependence and withdrawal will also increase. In children and adolescents who are not habitual caffeine users, vulnerability to caffeine intoxication may be markedly increased due to an absence of pharmacological tolerance. Genetic factors may also contribute to an individual’s vulnerability to caffeine related disorders including caffeine intoxication, dependence, and withdrawal. The combined use of caffeine and alcohol is increasing sharply, and studies suggest that such combined use may increase the rate of alcohol-related injury. Several studies suggest that energy drinks may serve as a gateway to other forms of drug dependence. Regulatory implications concerning labeling and advertising, and the clinical implications for children and adolescents are discussed. PMID:18809264

Treatment options for chronic pain management: opioids revisited.
Lipman, Arthur G
2007-02-01
Pain is a public health disaster. Although it remains largely undertreated, pharmacists and pharmacy managers can do much to correct the problem. Change will require the education of patients and health care professionals on the facts pertaining to addiction, drug dependence, and drug tolerance. Evidence-based resources, including guidelines published by the APS, should be consulted. A variety of short- and long-acting drugs are available, not the least of which are the opioids. Fears regarding addiction and uncertainty about tolerance have precluded the comprehensive use of these drugs, and varying dose requirements complicate the picture. What is known, however, is that dose titration must be performed with the goal of preventing breakthrough pain. Fortunately, sufficient drug formulae have been developed to accommodate this need. Pain is the primary reason why people come into the health care system, and it is incumbent upon health care professionals to eliminate insufficient pain control, using the drugs available to the patient's best advantage.

This study analyzes data related to Hospital (HOS), Public Treatment Service Dedicated to Drug Addicts (SERD), or Community Mental Health Center (CMHC) clients with a first diagnosis of Pathological Gambling (PG) in the period 2000/2016 in Northern Italy. The aims were to describe trends and characteristics of pathological gamblers (PGs) and to estimate the prevalence of other diagnoses before or after the diagnosis of PG. Participants aged over 17 years with an ICD-9 or ICD-10 PG diagnosis were selected. 680 PGs were identified, mean age 47.4 years, 20% female, 13% non-natives, 30% had other mental disorders diagnoses, 9% had alcohol dependence syndrome, and 11% had drug dependence. Most participants with comorbid disorders were diagnosed before PG, with a more elevated prevalence regarding mental disorders. Almost seven years had elapsed on average between the first admission and the diagnosis of PG. The results of this study highlight a growing demand for PG treatment addressed not only to SERD, but also to psychiatric and hospital services, based on the increase in SERD attendance from 2013. Many of them had already been treated for mental health problems before, but their percentage remained costant over time.

Research in adults shows that substance dependent individuals demonstrate attentional bias (AB) for substance-related stimuli. This study investigated the role of AB in adolescents diagnosed with alcohol, cannabis, amphetamine or GHB dependency on entering therapy and six months later, and the role of executive control (EC) as a moderator of the relationship between problem severity and AB. Seventy-eight young substance-dependent (SD) patients (mean age=19.5), and 64 healthy controls (HC; mean age=19.0) were tested. Thirty-eight SD patients took part at 6-month follow-up (FU). AB was indexed by a visual probe task, EC by the attention network task, problem severity by the short alcohol (or drug) use disorder identification test and the severity of dependence questionnaire. SD patients demonstrated an AB for substance stimuli presented for 500 ms and 1250 ms, with the latter related to severity of dependence. There was a nonsignificant tendency indicating that EC was higher in HC than SD participants, but EC did not moderate the relationship between AB and dependency. Substance use, dependency, EC and AB remained unchanged in the 6 month FU period. Young SD patients showed a stronger relatively early as well as maintained AB toward substance cues. A stronger maintained attention was related to higher severity of dependence. Further, there were some indications that EC might play a role in adolescent substance use. The finding that at FU AB and problem severity were not decreased, and EC was not increased underlines the persistent character of addiction. Copyright © 2015 Elsevier Ireland Ltd.

In Spain, the Therapeutic Community (TC) constitutes a common model of treatment in the field of addictions, although there hardly exists any investigation about its efficiency and the persistence of its attainments. To evaluate the short, half and long term effects of treatment of addiction to alcohol or cocaine in the TC run by "Fundacion Salud y Comunidad" (Foundation Health and Community). descriptive pilot study, with a sequential design of cohort. 91 users completed a survey specifically designed to know their evolution at different follow-up periods (1, 3, 5 or 10 years after their exit from the TC): socio-demographic, psychoactive substance use, other variables related to the stay at the TC. Changes between before the TC and the present time regarding variables such as academic, labour, drug consumption, health, family and social adaptation and their criminal behaviour are described. the cohorts showed a relatively common previous socio-demographic pattern having received a similar treatment. The users reported to have diminished the frequent consumption of the main drug, having 48.9% never relapsed even through an occasional consumption of the drug/s. Also they perceived to have improved their health and family relations, as well as their aggressive behaviour and legal problems linked with their consumption of drug/s. after their rehabilitation in a TC, the users report a global decrease of the consumption of drugs and perceive an improvement of their health, family relations, violence and other problems linked to their former drug use.
Time Investment in Drug Supply Problems by Flemish Community Pharmacies.
De Weerdt, Elfi; Simoens, Steven; Casteels, Minne; Huys, Isabelle
2017-01-01
Introduction: Drug supply problems are a known problem for pharmacies. Community and hospital pharmacies do everything they can to minimize impact on patients. This study aims to quantify the time spent by Flemish community pharmacies on drug supply problems. Materials and Methods: During 18 weeks, employees of 25 community pharmacies filled in a template with the total time spent on drug supply problems. The template stated all the steps community pharmacies could undertake to manage drug supply problems. Results: Considering the median over the study period, the median time spent on drug supply problems was 25 min per week, with a minimum of 14 min per week and a maximum of 38 min per week. After calculating the median of each pharmacy, large differences were observed between pharmacies: about 25% spent less than 15 min per week and one-fifth spent more than 1 h per week. The steps on which community pharmacists spent most time are: (i) "check missing products from orders," (ii) "contact wholesaler/manufacturers regarding potential drug shortages," and (iii) "communicating to patients." These three steps account for about 50% of the total time spent on drug supply problems during the study period. Conclusion: Community pharmacies spend about half an hour per week on drug supply problems. Although 25 min per week does not seem that much, the time spent is not delineated and community pharmacists are constantly confronted with drug supply problems.

The Good Behavior Game (GBG), a method of teacher classroom behavior management, was tested in first-and second-grade classrooms in 19 Baltimore City Public Schools beginning in the 1985–1986 school year. The intervention was directed at the classroom as a whole to socialize children to the student role and reduce aggressive, disruptive behaviors, confirmed antecedents of a profile of externalizing problem outcomes. This article reports on the GBG impact on the courses and interrelationships among aggressive, disruptive behavior through middle school, risky sexual behaviors, and drug abuse and dependence disorders through ages 19–21. In five poor to lower-middle class, mainly African American urban areas, classrooms within matched schools were assigned randomly to either the GBG intervention or the control condition. Balanced assignment of children to classrooms was made, and teachers were randomly assigned to intervention or control. Analyses involved multilevel growth mixture modeling. By young adulthood, significant GBG impact was found in terms of reduced high-risk sexual behaviors and drug abuse and dependence disorders among males who in first grade and through middle school were more aggressive, disruptive. A replication with the next cohort of first-grade children with the same teachers occurred during the following school year, but with minimal teacher mentoring and monitoring. Findings were not significant but generally in the predicted direction. A universal classroom-based prevention intervention in first- and second-grade classrooms can reduce drug abuse and dependence disorders and risky sexual behaviors. PMID:23070695

Several studies have correlated the use of one drug with that of another drug; however, whether dependence on one drug is associated with dependence on another drug, independent of any use/use association, is unclear. We asked 196 randomly-selected subjects the DSM-IV criteria for dependence as applied to alcohol, caffeine, and nicotine. Among ever users, the severity of alcohol vs nicotine dependence and alcohol vs caffeine dependence was related, but this relationship was weak (r = .22 & .31). Nicotine and caffeine dependence were not correlated. These results fail to confirm theories of commonality that hypothesize dependence on one drug predisposes to dependence on another drug.

Purpose To examine how prenatal heroin/cocaine exposure (PDE) and behavioral problems relate to adolescent drug experimentation. Methods The sample included African American adolescents (mean age=14.2 yr, SD=1.2) with PDE (n=73) and a non-exposed community comparison (n=61). PDE status was determined at delivery through toxicology analysis and maternal-report. Internalizing/externalizing problems were assessed during adolescence with the Behavior Assessment System for Children, Second Edition. Drug experimentation was assessed by adolescent-report and urine analysis. Logistic regression evaluated the likelihood of drug experimentation related to PDE and behavioral problems, adjusting for age, gender, prenatal tobacco/alcohol exposure, perceived peer drug use and caregiver drug use. Interaction terms examined gender modification. Results 67 (50%) used drugs. 25 (19%) used tobacco/alcohol only and 42 (31%) used marijuana/illegal drugs. 94 (70%) perceived peer drug use. PDE significantly increased the risk of tobacco/alcohol experimentation (OR=3.07, 95% CI: 1.09–8.66, p=0.034), but not after covariate adjustment (aOR=1.31, 95% CI: 0.39–4.36, p>0.05). PDE was not related to overall or marijuana/illegal drug experimentation. The likelihood of overall drug experimentation was doubled per Standard Deviation (SD) increase in externalizing problems (aOR=2.28, 95% CI: 1.33–3.91, p=0.003) and, among girls, 2.82 times greater (aOR=2.82, 95% CI: 1.34–5.94, p=0.006) per SD increase in internalizing problems. Age and perceived peer drug use were significant covariates. Conclusions Drug experimentation was relatively common (50%), especially in the context of externalizing problems, internalizing problems (girls only), age, and perceived peer drug use.

Malaysia is experiencing severe problems with heroin dependence and HIV infection. This, study evaluated drug use and other HIV risk behaviors and their association with HIV and other infectious diseases in heroin-dependent subjects enrolled in a clinical trial of drug abuse treatment in Muar, Malaysia. Baseline assessment of treatment-seeking subjects (n=177) included the Addiction Severity Index; AIDS Risk Inventory; serological tests for HIV, hepatitis B, and hepatitis C; and chest X-ray. All of the subjects were male; 67.8% were Malays, 28.8% Chinese, and 2.3%. Indian. Subjects had a mean (SD) age of 37.2 (9.1) years and 14.4 (8.5) years of using heroin; 76.3% reported lifetime injection drug use (IDU), and 41.5% reported current IDU; 30 of 156 (19.2%) tested HIV positive, 143 of 159 (89.9%) tested hepatitis C positive, and 25 of 159 (15.7%) had radiological evidence of pulmonary tuberbulosis. Malay subjects had a significantly higher prevalence of current IDU, needle sharing (p<0.01), and HIV infection (p<0.05) compared with Chinese subjects. Lifetime IDU, needle sharing, lack of consistent condom use, and Malay ethnicity were significantly associated with HIV infection. The high prevalence of HIV infection among heroin-dependent individuals, in Malaysia supports the important of interventions to reduce the major risk factors for HIV, including IDU, needle sharing, and unprotected sex.

We present a general mechanistic model of mass diffusion for a composite sphere placed in a large ambient medium. The multi-layer problem is described by a system of diffusion equations coupled via interlayer boundary conditions such as those imposing a finite mass resistance at the external surface of the sphere. While the work is applicable to the generic problem of heat or mass transfer in a multi-layer sphere, the analysis and results are presented in the context of drug kinetics for desorbing and absorbing spherical microcapsules. We derive an analytical solution for the concentration in the sphere and in the surrounding medium that avoids any artificial truncation at a finite distance. The closed-form solution in each concentric layer is expressed in terms of a suitably-defined inverse Laplace transform that can be evaluated numerically. Concentration profiles and drug mass curves in the spherical layers and in the external environment are presented and the dependency of the solution on the mass transfer coefficient at the surface of the sphere analyzed.

Anxiety disorders and externalizing problems are both associated with substance use disorders. However, the nature of this relationship remains unclear. To examine whether presence of an anxiety disorder changes the association between externalizing problems (conduct disorder, oppositional defiant disorder, and attention deficit hyperactivity disorder) and substance use disorders, we analyzed data from the National Comorbidity Survey-Replication, which is based on a nationally representative sample of 9282 English-speaking adults. Presence of externalizing problems was associated with an increased odds for alcohol abuse (OR: 6.7, CI: 5.6-8.1), alcohol dependence (OR: 7.6, CI: 5.9-9.6), substance abuse (OR: 9.9, CI: 8.1-12.2), and substance dependence (OR: 13.1, CI: 9.6-17.8). Similarly, anxiety disorders were associated with increased odds for substance use disorders. The highest association was found between post-traumatic stress disorder and substance use disorder (OR: 9.2, CI: 5.4-15.5). Individuals who met diagnostic criteria for an anxiety disorder and externalizing problems showed consistently and significantly lower odds for substance use problems than subjects with externalizing problems without a comorbid anxiety disorder. The results suggest that presence of any anxiety disorder reduces the association between externalizing problems and substance use disorders, possibly because the fear of bodily symptoms prevents individuals with externalizing problems from engaging in drug-seeking behaviors.
Noncompliance and drug toxicity in black, poor, and aged patients.
Miller, R L; Algee, J
1978-10-01
Drug toxicity is a common medical problem. Continued increases in drug toxicity are related to the extensive, indiscriminate use of drugs. This is a national health problem which is caused partly by gaps in pharmacology as a basic and clinical science and partly by the rapid proliferation of drugs (the drug explosion) in the past 30 years. Socioeconomically disadvantaged (black, poor, and aged) patients are particularly vulnerable to compliance problems and drug toxicity. In this presentation we discuss the basis for this increased vulnerability and suggest strategies that practicing physicians can use to minimize both compliance problems and drug toxicity.

Girls in the juvenile justice system are known to have high rates of co-occurring childhood abuse, trauma, and substance abuse. Girls with this constellation of problems are at high risk for serious adverse outcomes, including problems with drug dependence and abuse. The relationship between childhood sexual abuse, childhood physical abuse, other types of childhood trauma, and rates of substance use during adolescence were examined for girls in the juvenile justice system. As expected, childhood sexual abuse was significantly related to girls' substance use during adolescence. In contrast to prior research, no link was found between physical abuse, lifetime trauma, and substance use. Limitations and future directions are discussed.
The recovery paradigm - a model of hope and change for alcohol and drug addiction.
Best, David W; Lubman, Dan I

Alcohol and drug disorders remain major health and social problems in Australia, contributing enormously to the global burden of disease and the everyday practice of primary care. A recent growth in recovery research and recovery focused policies are starting to have an impact in Australia, with implications for how we attempt to resolve these problems. In this article we discuss recent international findings in recovery research, and explore their implications for primary care. Research indicates that over half of dependent substance users will eventually achieve stable recovery. Key predictors of recovery are active engagement in the community and immersion in peer support groups and activities. Recovery requires a twin track approach: enabling and supporting individual recovery journeys, while creating environmental conditions that enable and support a 'social contagion' of recovery, in which recovery is transmitted through supportive social networks and dedicated recovery groups, such as mutual aid.

Cases of people experiencing disturbed consciousness or dyspnea, causing traffic accidents, or requiring ambulance transport to hospital due to abuse of law-evading chemical substances have become a serious social problem in Japan. Most law-evading herbal products are marketed as incense or herbs and consist of finely chopped, dry vegetative matter mixed with chemical substances (drugs). Analysis of the chemical substances in these herbal products has demonstrated that they contain synthetic cannabinoids. Because there are many cannabinoid compounds, even if a particular drug is regulated, similar compounds that differ only slightly in structure may be added in their place. Therefore a cat-and-mouse game exists between regulations on chemical substances and their propagation. This paper summarizes the pharmacological actions and dangers of chemical substances contained in law-evading herbal products by focusing on synthetic cannabinoids, as a group of chemical substances contained in these products. Furthermore, comprehensive designations of synthetic cannabinoids have been introduced as a new method of regulation that emphasizes the similarity of chemical structures; this paper also outlines the comprehensive designations. We established a psychic-dependence liability and cytotoxicity screening system for synthetic cannabinoids using animals (behavioral analysis in vivo) and cell cultures (cytotoxicity analysis in vitro). With our drug-screening system, we were able rapidly to evaluate and quantify psychic-dependence liabilities and cytotoxicity of synthetic cannabinoids contained in law-evading herbal products. These scientific data using our screening system contributed to the establishment of legislation for comprehensive designations of synthetic cannabinoids.
Predictors of Illicit Drug/s Use Among University Students in Northern Ireland, Wales and England
Ansari, Walid El; Vallentin-Holbech, Lotte; Stock, Christiane
2015-01-01
Introduction: The use of illicit drug/s among university students is a public health concern. Nevertheless, many UK studies investigated a narrow spectrum of variables to explore their association/s with illicit drug/s use. Methods: We assessed the associations between a wide range of socio-demographic, health and wellbeing variables (independent variables) and having used illicit drug/s regularly, occasionally or never in life (dependent variables). Data (3706 students) were collected from seven universities in England, Wales, and Northern Ireland, using a self-administered questionnaire. Results: About 5% of the sample had regularly used illicit drug/s, 25% occasionally, and 70% never. Regular drug use (RDU) was significantly more likely among males aged 21-29 years, daily smokers, those with heavy episodic drinking or possible alcohol dependency (CAGE test), and those who perceived their academic performance better than their peers. RDU was less likely among students with high health awareness and those living with parents. The predictors of occasional drug use (ODU) were similar to those of RDU. However, in addition, students with higher perceived stress were less likely, and students who felt financial burden/s were more likely to report ODU, while no association with academic performance was found. Never use of illicit drug/s was inversely associated with most of the variables listed above, and was positively associated with religiosity. Illicit drug/s use goes along with other substance use (alcohol and smoking). The finding that illicit drug/s use was higher among students reporting good academic performance was surprising and raises the question of whether illicit drug/s may be used as performance enhancing drugs. Conclusion: The factors identified with illicit drug/s use in this study could be utilized to develop appropriate public health policies and preventive measures for the health of students. Multilevel, value based, comprehensive, and strategic long-term intervention plans are required. This could include social interventions aimed at generating recreations alternatives and opportunities for youth, and a critical review for current authorities’ interventions and services. Suggestions for coping with problems of campus illicit drug use/abuse also need to be offered. PMID:25946914

Analyses of data from two nationwide surveys of high school students, one carried out in 1974 and the other in 1978, suggest that problem drinking may be seen as yet another step along an underlying dimension of involvement with both licit and illicit drugs. The dimension of involvement with drugs consists of the following levels: nonuse of alcohol or illicit drugs; nonproblem use of alcohol; marijuana use; problem drinking; use of pills (amphetamines, barbiturates, hallucinogenic drugs); and the use of "hard drugs" such as cocaine or heroin. The dimension possesses excellent Guttman-scale properties in both national samples as well as in subsamples differing in gender and ethnic background. The ordering of the levels of involvement was confirmed by the ordering of the alcohol-drug involvement groups based on their mean scores on measures of psychosocial proneness for involvement in problem behavior. The excessive use of a licit drug, i.e., problem drinking, appears to indicate greater involvement in drug use than does the use of an illicit drug, marijuana. This finding points to the importance of distinguishing between use and problem use of drugs in efforts to understand adolescent drug involvement. PMID:6837819
Motivation for change and barriers to treatment among young cannabis users.

2013-01-01
Despite cannabis use among adolescents has shown to be related to psychosocial and mental health problems, the demand from adolescents for professional help is very low, and determinants of motivation for change among nonclinical populations remain unknown. The purpose of this study was to assess motivation for change among young cannabis users and to identify determinants of intention to change and self-change, as well as perceived barriers to seeking professional help. 261 cannabis users aged 16-21 participated in a computerized survey in Spain. Data from this cross-sectional study indicated that few users intend to stop taking the drug. Determining factors of intention to change were the following: having more drug-related problems, paranoid symptomatology and greater concern about the consequences of use. Self-change was facilitated by lower use of cannabis, and could be hindered by tobacco smoking and cannabis dependence. Lack of awareness of the problems and the desire to solve one's problems alone constitute the main barriers to seeking professional help. Adolescent cannabis users show low motivation for change though experiencing more problems associated with its use emerges as a determinant of increased motivation. Several barriers impede this motivation from turning into treatment demand. Copyright © 2012 S. Karger AG, Basel.

The aims of this study were to develop a bilingual version of the Semi-Structured Assessment for Drug Dependence and Alcoholism (SSADDA) in English and Samoan and determine the reliability of assessments of alcohol dependence in American Samoa. The study consisted of development and reliability-testing phases. In the development phase, the SSADDA alcohol module was translated and the translation was evaluated through cognitive interviews. In the reliability-testing phase, the bilingual SSADDA was administered to 40 ethnic Samoans, including a sub-sample of 26 individuals who were retested. Cognitive interviews indicated the initial translation was culturally and linguistically appropriate except items pertaining to alcohol tolerance, which were modified to reflect Samoan concepts. SSADDA reliability testing indicated diagnoses of DSM-III-R and DSM-IV alcohol dependence were reliable. Reliability varied by language of administration. The English/Samoan version of the SSADDA is appropriate for the diagnosis of DSM-III-R alcohol dependence, which may be useful in advancing research and public health efforts to address alcohol problems in American Samoa and the Western Pacific. The translation methods may inform researchers translating diagnostic and assessment tools into different languages and cultures. © The Author 2014.

Time Investment in Drug Supply Problems by Flemish Community Pharmacies
De Weerdt, Elfi; Simoens, Steven; Casteels, Minne; Huys, Isabelle
2017-01-01
Introduction: Drug supply problems are a known problem for pharmacies. Community and hospital pharmacies do everything they can to minimize impact on patients. This study aims to quantify the time spent by Flemish community pharmacies on drug supply problems. Materials and Methods: During 18 weeks, employees of 25 community pharmacies filled in a template with the total time spent on drug supply problems. The template stated all the steps community pharmacies could undertake to manage drug supply problems. Results: Considering the median over the study period, the median time spent on drug supply problems was 25 min per week, with a minimum of 14 min per week and a maximum of 38 min per week. After calculating the median of each pharmacy, large differences were observed between pharmacies: about 25% spent less than 15 min per week and one-fifth spent more than 1 h per week. The steps on which community pharmacists spent most time are: (i) “check missing products from orders,” (ii) “contact wholesaler/manufacturers regarding potential drug shortages,” and (iii) “communicating to patients.” These three steps account for about 50% of the total time spent on drug supply problems during the study period. Conclusion: Community pharmacies spend about half an hour per week on drug supply problems. Although 25 min per week does not seem that much, the time spent is not delineated and community pharmacists are constantly confronted with drug supply problems. PMID:28878679

The minority stress process of internalized homophobia (IH) has been associated with a range of adverse health outcomes among gay and bisexual men (GBM). However, evidence is mixed regarding the effect of IH on drug use, suggesting the potential role of multiple mediated pathways. Researchers have linked depression, sexual anxiety, and gay community attachment with IH. Depression, sexual anxiety, and gay community attachment have also been linked with drug use and drug-related problems suggesting potential mediating roles. A U.S. national sample of 1071 HIV-negative GBM completed at-home surveys, including measures of sociodemographic characteristics, IH, depression, sexual anxiety, gay community attachment, and drug use and associated problems. Adjusting for sociodemographic characteristics, depression mediated the association between IH and recent drug use. IH was positively associated with depression, and depression was positively associated with recent drug use. Gay community attachment partially mediated drug-related problems. IH had a positive direct association with drug-related problems and a negative direct association with gay community attachment. Gay community attachment had a positive association with drug-related problems. IH was positively associated with sexual anxiety, but sexual anxiety was not associated with either drug outcome. Efforts to reduce IH among HIV-negative GBM are likely to have a positive impact on mental health problems, as well as reduce risk for drug use and drug-related problems. Gay communities could provide the social support necessary for reducing IH; however, emphasis on community level interventions that address factors that increase risk for drug-related problems remains important.

Patients with diabetes often require complex medication regimens. The positive impact of pharmacists on improving diabetes management or its co-morbidities has been recognised worldwide. This study aimed to characterise drug-related problems among diabetic patients in Hong Kong and their clinical significance, and to explore the role of pharmacists in the multidisciplinary diabetes management team by evaluating the outcome of their clinical interventions. An observational study was conducted at the Diabetes Clinic of a public hospital in Hong Kong from October 2012 to March 2014. Following weekly screening, and prior to the doctor's consultation, selected high-risk patients were interviewed by a pharmacist for medication reconciliation and review. Drug-related problems were identified and documented by the pharmacist who presented clinical recommendations to doctors to optimise a patient's drug regimen and resolve or prevent potential drug-related problems. A total of 522 patients were analysed and 417 drug-related problems were identified. The incidence of patients with drug-related problems was 62.8% with a mean of 0.9 (standard deviation, 0.6) drug-related problems per patient. The most common categories of drug-related problems were associated with dosing (43.9%), drug choice (17.3%), and non-allergic adverse reactions (15.6%). Drugs most frequently involved targeted the endocrine or cardiovascular system. The majority (71.9%) of drug-related problems were of moderate clinical significance and 28.1% were considered minor problems. Drug-related problems were totally solved (50.1%) and partially solved (11.0%) by doctors' acceptance of pharmacist recommendations, or received acknowledgement from doctors (5.5%). Pharmacists, in collaboration with the multidisciplinary team, demonstrated a positive impact by identifying, resolving, and preventing drug-related problems in patients with diabetes. Further plans for sustaining pharmacy service in the Diabetes Clinic would enable further studies to explore the long-term impact of pharmacists in improving patients' clinical outcomes in diabetes management.

AIMS To determine whether electronic prescribing facilitates the uptake of clinical pharmacologists' recommendations for improving drug safety in medical inpatients. METHODS Electronic case records and prescription charts (either electronic or paper) of 502 patients hospitalized on medical wards in a large Swiss teaching hospital between January 2009 and January 2010 were studied by four junior and four senior clinical pharmacologists. Drug-related problems were identified and interventions proposed. The implementation and time delays of these proposed interventions were compared between the patients for whom paper drug charts were used and the patients for whom electronic drug charts were used. RESULTS One hundred and fifty-eight drug-related problems in 109 hospital admissions were identified and 145 recommendations were made, of which 51% were implemented. Admissions with an electronic prescription chart (n = 90) were found to have 2.74 times higher odds for implementation of the change than those with a paper prescription chart (n = 53) (95% confidence interval 1.2, 6.3, P = 0.018, adjusted for any dependency introduced by patient, ward or clinical team; follow-up for two cases missing). The time delay between recommendations being made and their implementation (if any) was minimal (median 1 day) and did not differ between the two groups. CONCLUSIONS Electronic prescribing in this hospital setting was associated with increased implementation of clinical pharmacologists' recommendations for improving drug safety when compared with handwritten prescribing on paper.

Drug abuse treatment programs typically recommend complete abstinence because of a fear that clients who stop use of one drug will substitute another. A within-subjects study investigated whether consumption of alcohol and other substances changes during marijuana abstinence. Twenty-eight daily marijuana users who were not trying to stop or reduce their marijuana consumption completed an 8-day baseline period in which they used marijuana and other drugs as usual, a 13-day marijuana abstinence period, and a 7-day return-to-baseline period. Participants provided self-report of substance use daily and submitted urine samples twice weekly to verify marijuana abstinence. A diagnosis of past alcohol abuse or dependence significantly moderated the alcohol increase from baseline to marijuana abstinence (p<0.01), such that individuals with this diagnosis significantly increased alcohol use (52% increase) but those without this history did not (3% increase). Increases in marijuana withdrawal discomfort scores and alcohol craving scores from baseline to marijuana abstinence significantly and positively correlated with increases in alcohol use. Increases in cigarettes, caffeine, and non-marijuana illicit drugs did not occur. This study provides empirical validation of drug substitution in a subgroup of daily marijuana users, but results need to be replicated in individuals who seek treatment for marijuana problems.

Background Disagreement among healthcare professionals on the clinical relevance of drug-related problems can lead to suboptimal treatment and increased healthcare costs. Elderly patients with chronic non-cancer pain and comorbidity are at increased risk of drug related problems compared to other patient groups due to complex medication regimes and transition of care. Objective To investigate the agreement among healthcare professionals on their classification of clinical relevance of drug-related problems in elderly patients with chronic non-cancer pain and comorbidity. Setting Multidisciplinary Pain Centre, Rigshospitalet, Copenhagen, Denmark. Method A pharmacist performed medication review on elderly patients with chronic non-cancer pain and comorbidity, identified their drug-related problems and classified these problems in accordance with an existing categorization system. A five-member clinical panel rated the drug-related problems' clinical relevance in accordance with a five-level rating scale, and their agreement was compared using Fleiss' κ. Main outcome measure Healthcare professionals' agreement on clinical relevance of drug related problems, using Fleiss' κ. Results Thirty patients were included in the study. A total of 162 drug related problems were identified, out of which 54% were of lower clinical relevance (level 0-2) and 46% of higher clinical relevance (level 3-4). Only slight agreement (κ = 0.12) was found between the panellists' classifications of clinical relevance using a five-level rating scale. Conclusion The clinical pharmacist identified drug related problems of lower and higher clinical relevance. Poor overall agreement on the severity of the drug related problems was found among the panelists.

The absorption of poorly water-soluble drugs, when presented in the crystalline state to the gastrointestinal tract, is typically dissolution rate-limited, and according to BCS these drugs belong mainly to class II. Both dissolution kinetics and solubility are particle size dependent. Nowadays, various techniques are available to the pharmaceutical industry for dissolution rate enhancement of such drugs. Among such techniques, nanosuspensions and drug formulation in solid dispersions are those with the highest interest. This review discusses strategies undertaken over the last 10 years, which have been applied for the dissolution enhancement of poorly water-soluble drugs; such processes include melt mixing, electrospinning, microwave irradiation and the use of inorganic nanoparticles. Many problems in this field still need to be solved, mainly the use of toxic solvents, and for this reason the use of innovative new procedures and materials will increase over the coming years. Melt mixing remains extremely promising for the preparation of SDs and will probably become the most used method in the future for the preparation of solid drug dispersions.

Social media offer insights of patients' medical problems such as drug side effects and treatment failures. Patient reports of adverse drug events from social media have great potential to improve current practice of pharmacovigilance. However, extracting patient adverse drug event reports from social media continues to be an important challenge for health informatics research. In this study, we develop a research framework with advanced natural language processing techniques for integrated and high-performance patient reported adverse drug event extraction. The framework consists of medical entity extraction for recognizing patient discussions of drug and events, adverse drug event extraction with shortest dependency path kernel based statistical learning method and semantic filtering with information from medical knowledge bases, and report source classification to tease out noise. To evaluate the proposed framework, a series of experiments were conducted on a test bed encompassing about postings from major diabetes and heart disease forums in the United States. The results reveal that each component of the framework significantly contributes to its overall effectiveness. Our framework significantly outperforms prior work. Published by Elsevier Inc.
[Management of adverse drug effects].

Adverse drug reactions (ADRs) are still considered one of the main problems of drug therapy. ADRs are associated with considerable morbidity, mortality, decreased compliance and therapeutic success as well as high direct and indirect medical costs. Several considerations have to come into play when managing a potential ADR. It is critical to establish an accurate clinical diagnosis of the adverse event. Combining information about drug exposure together with considering other possible causes of the reaction is crucial to establish a causal relationship between the reaction and the suspected drug. Identification of the underlying pathogenesis of an ADR together with the severity of the reaction will have profound implications on continuation of drug therapy after an ADR. Since spontaneous reports about ADRs are a key stone of a functioning post-marketing surveillance system and therefore play a key role in improving drug safety, health care professionals are highly encouraged to report ADRs to a local or national organization. However, because the majority of ADRs is dose-dependent and therefore preventable, individualization of pharmacotherapy may have a major impact on reducing such events.
Effect of differentiation of self on adolescent risk behavior: test of the theoretical model.
Knauth, Donna G; Skowron, Elizabeth A; Escobar, Melicia
2006-01-01
Innovative theoretical models are needed to explain the occurrence of high-risk sexual behaviors, alcohol and other-drug (AOD) use, and academic engagement among ethnically diverse, inner-city adolescents. The aim of this study was to test the credibility of a theoretical model based on the Bowen family systems theory to explain adolescent risk behavior. Specifically tested was the relationship between the predictor variables of differentiation of self, chronic anxiety, and social problem solving and the dependent variables of high-risk sexual behaviors, AOD use, and academic engagement. An ex post facto cross-sectional design was used to test the usefulness of the theoretical model. Data were collected from 161 racially/ethnically diverse, inner-city high school students, 14 to 19 years of age. Participants completed self-report written questionnaires, including the Differentiation of Self Inventory, State-Trait Anxiety Inventory, Social Problem Solving for Adolescents, Drug Involvement Scale for Adolescents, and the Sexual Behavior Questionnaire. Consistent with the model, higher levels of differentiation of self related to lower levels of chronic anxiety (p < .001) and higher levels of social problem solving (p < .01). Higher chronic anxiety was related to lower social problem solving (p < .001). A test of mediation showed that chronic anxiety mediates the relationship between differentiation of self and social problem solving (p < .001), indicating that differentiation influences social problem solving through chronic anxiety. Higher levels of social problem solving were related to less drug use (p < .05), less high-risk sexual behaviors (p < .01), and an increase in academic engagement (p < .01). Findings support the theoretical model's credibility and provide evidence that differentiation of self is an important cognitive factor that enables adolescents to manage chronic anxiety and motivates them to use effective problem solving, resulting in less involvement in health-comprising behaviors and increased academic engagement.
Noncompliance and Drug Toxicity in Black, Poor, and Aged Patients

Drug toxicity is a common medical problem. Continued increases in drug toxicity are related to the extensive, indiscriminate use of drugs. This is a national health problem which is caused partly by gaps in pharmacology as a basic and clinical science and partly by the rapid proliferation of drugs (the drug explosion) in the past 30 years. Socioeconomically disadvantaged (black, poor, and aged) patients are particularly vulnerable to compliance problems and drug toxicity. In this presentation we discuss the basis for this increased vulnerability and suggest strategies that practicing physicians can use to minimize both compliance problems and drug toxicity.

Insomnia is a serious medical and social problem, its prevalence in the general population ranges from 9 to 35% depending on the country and assessment method. Often, patients are subject to inappropriate and therefore dangerous pharmacotherapies that include prolonged administration of hypnotic drugs, benzodiazepines and other GABAA receptor modulators. This usually does not lead to a satisfactory improvement in patients' clinical states and may cause lifelong drug dependence. Brain state transitions require the coordinated activity of numerous neuronal pathways and brain structures. It is thought that orexin-expressing neurons play a crucial role in this process. Due to their interaction with the sleep-wake-regulating neuronal population, they can activate vigilance-promoting regions and prevent unwanted sleep intrusions. Understanding the multiple orexin modulatory effects is crucial in the context of pathogenesis of insomnia and should lead to the development of novel treatments. An important step in this process was the synthesis of dual antagonists of orexin receptors. Crucially, these drugs, as opposed to benzodiazepines, do not change the sleep architecture and have limited side-effects. This new pharmacological approach might be the most appropriate to treat insomnia.
Surveillance of drug resistance for tuberculosis control: why and how?
Chaulet, P; Boulahbal, F; Grosset, J
1995-12-01
The resistance of Mycobacterium tuberculosis to antibiotics, which reflects the quality of the chemotherapy applied in the community, is one of the elements of epidemiological surveillance used in national tuberculosis programmes. Measurement of drug resistance poses problems for biologists in standardization of laboratory methods and quality control. The definition of rates of acquired and primary drug resistance also necessitates standardization in the methods used to collect information transmitted by clinicians. Finally, the significance of the rates calculated depends on the choice of the patients sample on which sensitivity tests have been performed. National surveys of drug resistance therefore require multidisciplinary participation in order to select the only useful indicators: rates of primary resistance and of acquired resistance. These indicators, gathered in representative groups of patients over a long period, are a measurement of the impact of modern chemotherapy regimens on bacterial ecology.

This study examines associations between prescription opioid misuse and demographics, substance use, sexual behavior, and related health and social problems. Baseline data were collected between 2008 and 2010 from 515 high risk men who have sex with men (MSM), ages 18–55, in the Miami-Ft. Lauderdale metropolitan area who reported heavy substance use and HIV risk in the past 90 days. Prescription opioid misuse was associated with other substance use, drug injection, substance dependence, and history of arrest. Implications, limitations, and directions for future study are discussed. PMID:23971894

Adverse drug events are leading categories of iatrogenic patient injury. Development of preventive strategies for general practice setting depends on effective detection of events. The aim of the study is to compare the strengths and weaknesses of voluntary reporting, chart review and patient survey in measuring medication misadventures in general practice and to analyze the events by severity and preventability, drug groups and patients' and doctors' characteristics, for the formulation of preventive strategies. In the 2-month study period, we applied voluntary report, chart review and patient survey to collect data related to medication misadventures and compared their detection rate. The chart review demonstrated the highest yield for detecting overall medication misadventures (2.03% medication orders), followed by patient survey (1.46% medication orders) and voluntary reporting (0.52% medication orders). Chart review and patient survey were better than voluntary reporting in uncovering preventable adverse drug events. However, voluntary reporting was pivotal in capturing sentinel events. Beta-blocker, diuretic, angiotensin-converting enzyme inhibitor, aspirin and non-steroidal anti-inflammatory drugs had caused 82.0% of all adverse drug events. These events were more common with advanced age of patients, greater number of consultation problems and prescribed drug items. Additional resources implicated were minimal. We suggested a complementary approach using chart review and voluntary reporting in measuring and monitoring medication misadventures in general practice. Close monitoring of the events was necessary for older patients, multiple medical problems and poly-pharmacy and for patients using beta-blocker, diuretic, angiotensin-converting enzyme inhibitor, aspirin or non-steroidal anti-inflammatory drugs on a long-term basis.
hERG trafficking inhibition in drug-induced lethal cardiac arrhythmia.
Nogawa, Hisashi; Kawai, Tomoyuki
2014-10-15
Acquired long QT syndrome induced by non-cardiovascular drugs can cause lethal cardiac arrhythmia called torsades de points and is a significant problem in drug development. The prolongation of QT interval and cardiac action potential duration are mainly due to reduced physiological function of the rapidly activating voltage-dependent potassium channels encoded by human ether-a-go-go-related gene (hERG). Structurally diverse groups of drugs are known to directly inhibit hERG channel conductance. Therefore, the ability of acute hERG inhibition is routinely assessed at the preclinical stages in pharmaceutical testing. Recent findings indicated that chronic treatment with various drugs not only inhibits hERG channels but also decreases hERG channel expression in the plasma membrane of cardiomyocytes, which has become another concern in safety pharmacology. The mechanisms involve the disruption of hERG trafficking to the surface membrane or the acceleration of hERG protein degradation. From this perspective, we present a brief overview of mechanisms of drug-induced trafficking inhibition and pathological regulation. Understanding of drug-induced hERG trafficking inhibition may provide new strategies for predicting drug-induced QT prolongation and lethal cardiac arrhythmia in pharmaceutical drug development.

Background Due to marginalization, trafficking violence, conflicts with the police and organic and social psychological problems associated with the drug, crack is one of the most devastating drugs currently in use. However, there is evidence that some users manage to stay alive and active while using crack cocaine for many years, despite the numerous adversities and risks involved with this behavior. In this context, the aim of the present study was to identify the strategies and tactics developed by crack users to deal with the risks associated with the culture of use by examining the survival strategies employed by long-term users. Method A qualitative research method was used involving semi-structured, in-depth interviews. Twenty-eight crack users fulfilling a pre-defined enrollment criterion were interviewed. This criterion was defined as the long-term use of crack (i.e., at least four years). The sample was selected using information provided by key informants and distributed across eight different supply chains. The interviews were literally transcribed and analyzed via content analysis techniques using NVivo-8 software. Results There was diversity in the sample with regard to economic and education levels. The average duration of crack use was 11.5 years. Respondents believed that the greatest risks of crack dependence were related to the drug's psychological effects (e.g., cravings and transient paranoid symptoms) and those arising from its illegality (e.g., clashes with the police and trafficking). Protection strategies focused on the control of the psychological effects, primarily through the consumption of alcohol and marijuana. To address the illegality of the drug, strategies were developed to deal with dealers and the police; these strategies were considered crucial for survival. Conclusions The strategies developed by the respondents focused on trying to protect themselves. They proved generally effective, though they involved risks of triggering additional problems (e.g., other dependencies) in the long term. PMID:21050465
Substance abuse in anaesthetists.
Garcia-Guasch, Roser; Roigé, Jaume; Padrós, Jaume
2012-04-01
Anaesthesiologists have a significantly higher frequency of substance abuse by a factor of nearly 3 when compared with other physicians. This is still a current problem that must be reviewed. Many hypotheses have been formulated to explain why anaesthesiologists appear to be more susceptible to substance abuse than other medical professionals (genetic differences in sensitivity to opioids, stress, the association between chemical dependence and other psychopathology or the second-hand exposure hypothesis). Environmental exposure and sensitization may be an important risk factor in physician addiction. There is a long debate about returning to work for an anaesthetist who has been depending on opioid drugs, and recent debates are discussed. Institutional efforts have been made in many countries and physician health programmes have been developed. As drug abuse among anaesthesiologists has continued, new studies have been conducted to know the theories about susceptibility. Written substance abuse policies and controls must be taken in place and in all countries.
Homoeopathy and the treatment of alcohol-related problems.
Rogers, J
1997-02-01
This paper discusses the use of homoeopathy in the work of a community alcohol team, focusing on the application of homoeopathy for treating sleep disorder in alcohol-dependent clients. This work is placed in the context of the historical use of homoeopathy for treating 'alcoholism' and of the increasing use of complementary therapies in mainstream health care and in drug and alcohol agencies. Issues of research methodology and measurement of outcomes are examined. Examples of some specific homoeopathic treatments, together with a case report, are given to illustrate the potential uses of this form of therapy. It is concluded that homoeopathy can provide a valid and effective therapy to help clients break the cycle of dependence on alcohol. A number of further research questions arise and much clinical and research work needs to be done by those attempting to bring complementary therapies into drug and alcohol treatment.
Drug Prohibition in the United States: Costs, Consequences, and Alternatives

``Drug legalization'' increasingly merits serious consideration as both an analytical model and a policy option for addressing the ``drug problem.'' Criminal justice approaches to the drug problem have proven limited in their capacity to curtail drug abuse. They also have proven increasingly costly and counterproductive. Drug legalization policies that are wisely implemented can minimize the risks of legalization, dramatically reduce the costs of current policies, and directly address the problems of drug abuse.

Most trauma surgeons are unfamiliar with screening, brief intervention, and referral (SBIR) programs for substance use disorders, and few trauma centers provide them. This report describes how an urban private-teaching hospital adapted a protocol from an existing emergency department-based program to include patients treated by the trauma service. We recorded the rates of SBIR completion and reasons for failure during each phase of the implementation, interviewed trauma service staff and health educators to assess attitudes toward the program, and evaluated patient satisfaction surveys. By adding SBIR staff to the trauma outpatient clinic and to trauma morning rounds, the capture rate increased from 12 to 71%. Most screened patients (59%) were found at risk for problems or probably dependent on alcohol or drugs. Trauma service staff and health educators reported high satisfaction with the program. Patients reported higher satisfaction with SBIR. SBIR services can be effectively integrated into all components of a busy, urban trauma service by adding specially trained health educators to the trauma service staff. This collaboration provides effective SBIR services to both trauma and emergency service patients without interfering with patient flow or medical procedures. The relatively high percentage of patients at risk for alcohol or drug problems supports the inclusion of routine alcohol and drug screening for all eligible trauma patients.

Despite over-representation of Indigenous Australians in sentinel studies of injecting drug use, little is known about relevant patterns of drug use and dependence. This study compares drug dependence and possible contributing factors in Indigenous and non-Indigenous Australians who inject drugs. Respondent-driven sampling was used in major cities and 'peer recruitment' in regional towns of Queensland to obtain a community sample of Indigenous (n = 282) and non-Indigenous (n = 267) injectors. Data are cross sectional. Multinomial models were developed for each group to examine types of dependence on injected drugs (no dependence, methamphetamine-dependent only, opioid-dependent only, dependent on methamphetamine and opioids). Around one-fifth of Indigenous and non-Indigenous injectors were dependent on both methamphetamine and opioids in the previous 12 months. Psychological distress was associated with dual dependence on these drugs for Indigenous [adjusted relative risk (ARR) 4.86, 95% confidence interval (CI) 2.08-11.34] and non-Indigenous (ARR 4.14, 95% CI 1.59-10.78) participants. Unemployment (ARR 8.98, 95% CI 2.25-35.82) and repeated (> once) incarceration as an adult (ARR 3.78, 95% CI 1.43-9.97) were associated with dual dependence for Indigenous participants only. Indigenous participants had high rates of alcohol dependence, except for those dependent on opioids only. The drug dependence patterns of Indigenous and non-Indigenous people who inject drugs were similar, including the proportions dependent on both methamphetamine and opioids. However, for Indigenous injectors, there was a stronger association between drug dependence and contextual factors such as unemployment and incarceration. Expansion of treatment options and community-level programs may be required. [Smirnov A, Kemp R, Ward J, Henderson S, Williams S, Dev A, Najman J M.

Frequency of 5+/4+ drinks as a screener for drug use and drug-use disorders.
Dawson, Deborah A; Compton, Wilson M; Grant, Bridget F
2010-09-01
The objective of this study was to test the ability of a question on frequency of drinking 5+ (for men) or 4+ (for women) drinks to screen for drug use and drug-use disorders (DUDs) in a general population sample. Using data collected in 2001-2002 from a representative U.S. adult population sample (N= 43,093), including a subsample of those with past-year emergency-department use (n = 8,525), past-year frequency of drinking 5+/4+ drinks was evaluated as a screener for drug use and DUDs for four categories of illicit drugs. Sensitivities and specificities of the 5+/4+ drinks screener were 72.4% and 76.6% for any drug dependence, 71.9% and 77.3% for any DUD, and 63.3% and 78.9% for any drug use in the general population. Sensitivities and specificities were higher for marijuana and cocaine/crack and lowest for illicit prescription drugs. Optimal screening cut-points were once a month or more for cocaine/crack dependence, either once or more a month or seven or more times a year for cocaine/crack DUDs, seven or more times a year for cocaine/crack use, and once or more a year for the other drug use and DUD measures. Sensitivity and specificity were similar among adults who had visited an emergency department in the past year, and the optimal screening cutpoints were identical. Past-year frequency of drinking 5+/4+ drinks was quite accurate as a screener for past-year marijuana and cocaine/crack use and DUDs, but it was less accurate for illicit prescription drug use and DUDs. Its drug-screening potential can be thought of as "added value" from an item already likely to be asked in the interest of detecting problem drinking. Future work may consider using the alcohol consumption screener as a starting point, with follow-up questions to assess illicit drug use among those who screen positive.
Frequency of 5+/4+ Drinks as a Screener for Drug Use and Drug-Use Disorders*

Patients admitted to general internal medicine wards might receive a large number of drugs and be at risk for drug-related problems (DRPs) associated with increased morbidity and mortality. This study aimed to detect suboptimal drug use in internal medicine by a pharmacotherapy evaluation, to suggest treatment optimizations and to assess the acceptance and satisfaction of the prescribers. This was a 6-month prospective study conducted in two internal medicine wards. Physician rounds were attended by a pharmacist and a pharmacologist. An assessment grid was used to detect the DRPs in electronic prescriptions 24h in advance. One of the following interventions was selected, depending on the relevance and complexity of the DRPs: no intervention, verbal advice of treatment optimization, or written consultation. The acceptance rate and satisfaction of prescribers were measured. In total, 145 patients were included, and 383 DRPs were identified (mean: 2.6 DRPs per patient). The most frequent DRPs were drug interactions (21%), untreated indications (18%), overdosages (16%) and drugs used without a valid indication (10%). The drugs or drug classes most frequently involved were tramadol, antidepressants, acenocoumarol, calcium-vitamin D, statins, aspirin, proton pump inhibitors and paracetamol. The following interventions were selected: no intervention (51%), verbal advice of treatment optimization (42%), and written consultation (7%). The acceptance rate of prescribers was 84% and their satisfaction was high. Pharmacotherapy expertise during medical rounds was useful and well accepted by prescribers. Because of the modest allocation of pharmacists and pharmacologists in Swiss hospitals, complementary strategies would be required. Copyright © 2015 European Federation of Internal Medicine.

The challenge in developing oral drug delivery systems of poorly soluble basic drugs is primarily due to their pH dependent solubility. Cinnarizine (CNZ), a model for a poorly soluble basic drug, has pH dependent solubility; where it dissolves readily at low pH in the stomach and exhibits a very low solubility at pH values greater than 4. It is also characterized by a short half life of 3-6h, which requires frequent daily administration resulting in poor patient compliance. In an attempt to solve these problems, extended release floating lipid beads were formulated. A 2(4) full factorial design was utilized for optimization of the effects of various independent variables; lipid:drug ratio, % Pluronic F-127, % Sterotex, and Gelucire 43/01:Gelucire 50/13 ratio, on the loading efficiency and release of CNZ from the lipid beads. In-vivo pharmacokinetic study of the optimized CNZ-lipid beads compared to Stugeron® (reference standard) was performed in healthy human volunteers. A promising approach for enhancing the bioavailability of the poorly soluble basic drug, CNZ, utilizing novel and simple floating lipid beads was successfully developed. Zero order release profile of CNZ was achieved for 12h. Mean AUC0-24 and AUC0-∞ of the optimized CNZ-loaded lipid beads were 4.23 and 6.04 times that of Stugeron® tablets respectively.

Purpose Stigma-related feelings, including degree of enthusiasm and willingness to work with alcohol, drug, and mental disorder (ADM) patients, as well as anticipated success in such work, will be required for the United States to be successful in its new initiatives for ADM screening, brief intervention, and effective referral to treatment and rehabilitation services (SBIRT). This study investigates students of medicine and social work with respect to their stigma-related feelings and degree of enthusiasm or willingness to treat patients affected by alcohol dependence, nicotine dependence, or major depression. Inference is strengthened by an anonymous online survey approach, with use of randomized reinforcers to gain at least partial experimental control of nonparticipation biases that otherwise are present in student survey data. Material and methods All students on required course rosters were asked to participate in a two-part in-class and online assessment; 222 participated, with a gradient of participation induced via randomly drawn reinforcers for online survey participation. Between-group comparisons were made with a multivariate generalized linear model and generalized estimating equations approach that adjusts for covariates. Results Medical and social work students did not differ from each other with respect to their willingness to treat patients affected by major depression, alcohol dependence, or nicotine dependence, but together were less willing to treat nicotine and alcohol dependence-affected patients as compared to depression-affected patients. Personal history was not associated with the students’ willingness to treat, but men were less willing to treat. Drawing strength from the randomized reinforcer experimental design nested within this survey approach, the study evidence suggests potential nonparticipation bias in standard surveys on this topic. Conclusion These results indicate that future health professionals may prefer to treat depression as opposed to drug dependence conditions. For SBIRT success, curriculum change with educational interventions may be needed to increase willingness to treat patients with neuropsychiatric conditions such as drug dependence. Future research requires attention to a possible problem of nonparticipation bias in surveys of this type. PMID:21731413

This study examined whether posttraumatic stress specifically resulting from intimate partner violence (IPV-related posttraumatic stress) mediated relationships between types of IPV and drug and alcohol problems among 212 women currently experiencing IPV. Six-month prevalence was high for drug use (48%) and alcohol use (59%). Structural equation modeling revealed that the frequency of physical, sexual, and psychological IPV were significantly and positively related to greater IPV-related posttraumatic stress, and IPV-related posttraumatic stress was significantly and positively related to drug problems. Further, IPV-related posttraumatic stress mediated the relationships between physical IPV and drug problems and psychological IPV and drug problems. Findings suggest that prevention and intervention efforts targeting posttraumatic stress among IPV-exposed women may reduce drug problems in this population.

Relationships were explored among the frequencies of use of various drugs by a sample of drug-abusing clients of the Addiction Research Foundation (ARF) in Toronto and by drug abusers volunteering to participate in research at the Addiction Research Center (ARC) in Baltimore. The two groups of drug-abusing individuals differed in a number of characteristics. Those from ARF were admitted primarily for diagnosis and possible treatment for alcohol and non-opioid drug problems, whereas those from the ARC were admitted for participation in research on other drugs of abuse, primarily involving opioids. Patterns of use of certain drugs tended to covary in both groups. Of particular interest was the finding that severity of alcoholism was directly related to various measures of tobacco and caffeinated beverage use. In contrast, there was little correlation between the frequency of use among other drugs of abuse (e.g., heroin, cannabis, glue) and the use of tobacco and caffeine. These findings suggest that dependence on nicotine, caffeine, and alcohol may be governed by the same factors and possibly should be considered jointly in the treatment of alcoholic persons. Frequency of use of other drugs examined may be controlled by other factors than those which determine level of use of tobacco and caffeine.
Methamphetamine Cured my Cocaine Addiction

Cocaine dependence is an enduring problem and years of research and drug development has yet to produce an efficacious pharmacotherapy. Recent clinical research suggests that chronic treatment with amphetamine-like medications produces tolerance to cocaine’s reinforcing effects and may offer a viable pharmacotherapy. Three methamphetamine-dependent participants that had been in our clinical laboratory experiments and previously addicted to cocaine are reviewed. Data obtained from initial screen and informal conversation suggested that all participants considered methamphetamine to have helped them stop using cocaine and eliminate cocaine craving. Methamphetamine also significantly decreased their alcohol consumption but did not alter cannabis or nicotine use. PMID:23066512

To measure agreement between advanced pharmacy practice experience students using a guided interview process and experienced clinical pharmacists using standard practices to identify drug therapy problems. Student pharmacists enrolled in an advanced pharmacy practice experience (APPE) and clinical pharmacists conducted medication therapy management interviews to identify drug therapy problems in elderly patients recruited from the community. Student pharmacists used a guided interview tool, while clinical pharmacists' interviews were conducted using their usual and customary practices. Student pharmacists also were surveyed to determine their perceptions of the interview tool. Fair to moderate agreement was observed on student and clinical pharmacists' identification of 4 of 7 drug therapy problems. Of those, agreement was significantly higher than chance for 3 drug therapy problems (adverse drug reaction, dosage too high, and needs additional drug therapy) and not significant for 1 (unnecessary drug therapy). Students strongly agreed that the interview tool was useful but agreed less strongly on recommending its use in practice. The guided interview process served as a useful teaching aid to assist student pharmacists to identify drug therapy problems.

Drug-related visits to the emergency department: how big is the problem?
Patel, Payal; Zed, Peter J
2002-07-01
To review the literature concerning drug-related problems that result in emergency department visits, estimate the frequency of these problems and the rates of hospital admissions, and identify patient risk factors and drugs that are associated with the greatest risk. A systematic search of MEDLINE (January 1966-December 2001), EMBASE (January 1980-December 2001), and PubMed (January 1966-December 2001) databases for full reports published in English was performed. The Ottawa Valley Regional Drug Information Service database of nonindexed pharmacy journals also was searched. Data from eight retrospective and four prospective trials retrieved indicated that as many as 28% of all emergency department visits were drug related. Of these, 70% were preventable, and as many as 24% resulted in hospital admission. Drug classes often implicated in drug-related visits to an emergency department were nonsteroidal antiinflammatory drugs, anticonvulsants, antidiabetic drugs, antibiotics, respiratory drugs, hormones, central nervous system drugs, and cardiovascular drugs. Common drug-related problems resulting in emergency department visits were adverse drug reactions, noncompliance, and inappropriate prescribing. Drug-related problems are a significant cause of emergency department visits and subsequent resource use. Primary caregivers, such as family physicians and pharmacists, should collaborate more closely to provide and reinforce care plans and monitor patients to prevent drug-related visits to the emergency department and subsequent morbidity and mortality.

The gabapentinoids pregabalin and gabapentin are being increasingly prescribed for a range of clinical conditions. Recently, although gabapentinoids at therapeutic dosages may present with low addictive liability levels, cases of misuse and rising numbers of related fatalities have been reported. The aim of the study was to identify and assess cases of gabapentinoid misuse or dependence as reported to the European Medicines Agency's EudraVigilance database, to identify the magnitude of this problem and the characteristics of these reactions. All spontaneous reports of both gabapentin- (2004-2015) and pregabalin- (2006-2015) related misuse/abuse/dependence were retrieved. A descriptive analysis by source, sex, age, and type of report was performed. From the EudraVigilance database 7639 (6.6 % of a total of 115,616) and 4301 (4.8 % of 90,166) adverse drug reaction reports of misuse/abuse/dependence were, respectively, associated with pregabalin and gabapentin, with an overall reporting frequency increasing over time. For both molecules, subjects typically involved were female adults. A total of 27 and 86 fatalities, respectively, associated with pregabalin and gabapentin, and mostly in combination with opioids, were identified. Analysis of proportional reporting ratios for drug abuse/dependence/intentional product misuse values seem to indicate that these adverse drug reactions were more frequently reported for pregabalin (1.25, 1.39, and 1.58, respectively) compared with gabapentin. Despite data collection/methodological approach limitations, the present data seem to suggest that gabapentinoid misuse may be a cause for concern, especially in patients with a history of substance misuse. Hence, healthcare professionals should be vigilant when prescribing these molecules.

Young women who regularly attend nightclubs are at risk for numerous health and social consequences, including mental distress, sexual and physical victimization and substance dependence. This paper uses a biopsychosocial framework to examine co-occurring mental health problems, victimization, substance dependence, sexual risk and physical pain among a sample of young women who use drugs (N = 222) in Miami's club scene. The majority of women were under 24 years old, Hispanic, and identified as heterosexual. Almost all the women reported past 90-day use of alcohol, ecstasy/MDMA, marijuana, cocaine and prescription opioids and benzodiazepines; 32% of women reported being in a monogamous relationship while 41.9% reported having three or more sexual partners in the past 90 days; 65.3% met DSM-IV criteria for substance dependence; 60.4% met DSM-IV criteria for serious mental illness (SMI) and 59.9% were victimized as minors. Women who had SMI had higher odds of substance dependence, concurrent physical pain, three or more sexual partners in the past 90 days, childhood victimization and severe abuse-related trauma. The high levels of interconnected mental health, victimization, trauma, physical pain, substance dependence and sexual risk factors observed are underreported in the literature, as young women club scene participants appear to be more similar to other marginalized drug-involved populations than previously considered. While further research is needed, it appears these young women are in great need of outreach for primary health, mental health, HIV prevention, increased social support and substance abuse treatment services.

Coutinho, Daniel; Vieira, Duarte Nuno; Teixeira, Helena M
2011-01-01
Benzodiazepines are drugs usually used in anxiety disorders, dyssomnias, convulsions, muscle disorders, alcohol and other drugs detoxification, as well as in preoperative sedation/amnesia. Moreover, antidepressants are mainly indicated in depression and as co-therapeutic drugs in other psychiatric disorders. The use of benzodiazepines and antidepressants is associated with some health and public safety problems. Decreased of attention, concentration, reflexes, visual capacity, motor coordination and reasoning, associated with increased reaction time and lack of awareness of driving impairment among these drug users, contributes to the increased risk on traffic safety linked with these drugs. This risk may further increase with non-compliance of medical prescription, drug abuse or concomitant use of alcohol. The relationship between the use of psychoactive drugs and road traffic safety is, however, an extremely complex subject and has a primordial importance in the clarification of the role of benzodiazepine and antidepressant effects on driving skills. The prevention of driving under the influence of these drugs depends on the awareness, among doctors, of the risks associated with their use. Thus, the consciousness of medical prescription, as well as providing clear information to patients is extremely important.
Treatment in England of Canadian Patients Addicted to Narcotic Drugs
Frankau, Lady
1964-01-01
The method of treatment and the results obtained from the treatment of 50 Canadian patients addicted to narcotic drugs who went to England are recorded. These patients were first stabilized on the minimal dose of narcotic drug which permitted them to work, and to acquire security and self-respect. Then, after psychiatric treatment dealing with the basic problem of their personality disorder, complete withdrawal treatment of the narcotic drug was undertaken. Nine of 10 patients aged between 20 and 30, of good social and cultural background, have been relieved of dependence on drugs for over two years. The other 40 patients came from a different background. Nearly all had been imprisoned for drug offences and they had come to England to obtain treatment and to avoid further prison sentences in Canada. The 31 patients whose prison sentences had been directly connected with drug offences are working steadily and leading an apparently normal life. The remaining nine patients had been convicted of criminal acts before becoming addicted to narcotic drugs and, with two exceptions, the results of their treatment compare unfavourably with the other patients, seven having been convicted and imprisoned in London.

Not everyone who takes drugs becomes addicted, but the likelihood of developing drug addiction is greater in people with a family history of drug or alcohol dependence. Relatively little is known about how genetic risk mediates the development of drug dependence. By comparing the phenotypic profile of individuals with and without a family history of addiction, the authors sought to clarify the extent to which cognitive dysfunction and personality traits are shared by family members--and therefore likely to have predated drug dependence--and which aspects are specific to drug-dependent individuals. The authors assessed cognitive function and personality traits associated with drug dependence in stimulant-dependent individuals (N=50), their biological siblings without a history of drug dependence (N=50), and unrelated healthy volunteers (N=50). Cognitive function was significantly impaired in the stimulant-dependent individuals across a range of domains. Deficits in executive function and response control were identified in both the stimulant-dependent individuals and in their non-drug-dependent siblings. Drug-dependent individuals and their siblings also exhibited elevated anxious-impulsive personality traits relative to healthy comparison volunteers. Deficits in executive function and response regulation as well as anxious-impulsive personality traits may represent endophenotypes associated with the risk of developing cocaine or amphetamine dependence. The identification of addiction endophenotypes may be useful in facilitating the rational development of therapeutic and preventive strategies.
Parenting and children's externalizing problems in substance-abusing families.
Stanger, Catherine; Dumenci, Levent; Kamon, Jody; Burstein, Marcy
2004-09-01
This study tested associations in path models among positive and negative parenting and children's rule-breaking behavior, aggressive and oppositional behavior, and attention problems for families with a drug-dependent parent. A structural model tested relations between parenting and children's externalizing problems for 251 families with 399 children between the ages of 6 and 18, controlling for nonindependence of ratings at the family level. The model also tested potential moderators, including child age, gender, and ethnicity (White vs. other), and caregiver gender (families with a female substance-abusing caregiver vs. families with a male substance-abusing caregiver). Results indicated that caregiver ratings of monitoring predicted rule-breaking behavior and use of inconsistent discipline predicted ratings of all 3 externalizing syndromes, after controlling parenting and externalizing problems for the effects of the moderators and after controlling significant relations among types of parenting and types of externalizing problems.
Addiction liability of pharmacotherapeutic interventions in obesity.
Greene, William M; Sylvester, Mark; Abraham, Joel
2011-01-01
Obesity and substance use disorders are rapidly growing problems throughout the world. Of the current mainstay therapies of diet, exercise, behavioral modification, surgery, and medications, drugs have the greatest risk for abuse and dependence. As each of these disorders share similar underpinnings mediated by the dopaminergic brain reward pathways, clinicians must seriously consider the safety of both the patient's physical and mental health when prescribing treatments. Specifically, balance and awareness of the factors involved in the variable abuse potentials of these prescribed medications is paramount. A cursory review of weight loss medications commonly used is performed with attention to FDA status, mechanism of action, and abuse potential. Concurrent strategies to minimize risk such as drug screening, ruling out doctor shopping, temporal considerations, monitoring for signs and symptoms of abuse and/or dependency, and a safety-tiered prescribing approach is also discussed in order to optimize best treatment practice. As the understanding of these disorders progresses along with the evolution of agreed nomenclature and awareness of compulsive behavioral disorders in general, greater safety and more appropriate interventions may be achieved. Further areas of research will help to elucidate nuances of the coocurrance and treatment of these disorders and perhaps guide drug research and development in the area of drug treatments of obesity.
Drug related problems with Antiparkinsonian agents: consumer Internet reports versus published data.
Schröder, Sabrina; Zöllner, York Francis; Schaefer, Marion
2007-10-01
There is currently a lack of detailed information concerning drug related problems in the outpatient treatment of Parkinson's disease. Problems associated with drug treatment communicated anonymously in Parkinson's disease online forums were therefore retrospectively searched and documented for 1 year. Based on postings concerning 12 drugs for the treatment of Parkinson's disease, a total of 238 drug related problems were identified and categorised using the Problem Intervention Documentation (PI-Doc). Of these, 153 were adverse drug reactions. Adverse drug reactions associated with the skin were relatively common, but central effects such as cognitive or psychiatric changes, effects on the sleep/waking system and other problems like headache and dizziness accounted for the highest percentage of adverse events. A comparison with data from scientific literature revealed a number of differences. This means that an analysis of online forums detected a number of drug related problems that were otherwise largely invisible. These were mainly associated with the qualitative aspects of treatment such as medication handling, dosage and individual problems concerning adverse events. In addition, the described method of identifying and classifying drug related problems in Internet forums may also be seen as a contribution to the international discussion about consumer reports and pharmacovigilance. The information about adverse drug reactions given by Internet users can be seen as a valuable adjunct to clinical trial data and as being very timely with regard to the event itself. Online forums may be considered as a suitable source of observational information to complement data from randomised clinical trials.
[Type 2 diabetes mellitus: new treatments].
Ascaso, Juan F
2014-08-04
The benefits and problems associated with traditional hypoglycemic drugs, such as failure of beta cells, hypoglycemia and weight gain, that lead to a worsening of diabetes, are reviewed. New hypoglycemic drugs with incretin effect (glucagon-like peptide-1 agonists and dipeptidyl peptidase 4 inhibitors), achieve, in a glucose dependent manner, an glycosylated hemoglobin reduction without hypoglycemia or increase in body weight. Recently, another group of oral hypoglycemic drugs, sodium-glucose cotransporter type 2 inhibitors, have demonstrated efficacy in diabetes control by inhibiting renal glucose reabsorption. However, long-term effects and cardiovascular prevention remain to be demonstrated. We have more and better drugs nowadays. Hypoglycemic treatment should be customized (glycosylated hemoglobin levels, risk-benefit, risk of hypoglycemia, weight changes, cardiovascular risk), with a combination of drugs being necessary in most cases. However, we do not have yet an ideal hypoglycemic drug. Moreover we must remember that an early and intensive treatment of dyslipidemia and hypertension is essential for the prevention of cardiovascular disease in patients with type 2 diabetes.

Adaptive Interventions in Drug Court: A Pilot Experiment

This pilot study (N = 30) experimentally examined the effects of an adaptive intervention in an adult misdemeanor drug court. The adaptive algorithm adjusted the frequency of judicial status hearings and clinical case-management sessions according to pre-specified criteria in response to participants' ongoing performance in the program. Results revealed the adaptive algorithm was acceptable to both clients and staff, feasible to implement with greater than 85% fidelity, and showed promise for eliciting clinically meaningful improvements in drug abstinence and graduation rates. Estimated effect sizes ranged from 0.40 to 0.60 across various dependent measures. Compared to drug court as-usual, participants in the adaptive condition were more likely to receive responses from the drug court team for inadequate performance in the program and received those responses after a substantially shorter period of time. This suggests the adaptive algorithm may have more readily focused the drug court team's attention on poorly-performing individuals, thus allowing the team to “nip problems in the bud” before they developed too fully. These preliminary data justify additional research evaluating the effects of the adaptive algorithm in a fully powered experimental trial. PMID:19724664

The objective of the present study was to develop pH-independent/dependent sustained release (SR) tablets of ondansetron HCl dihydrate (OND), a selective 5-HT3 receptor antagonist that is used for prevention of nausea and vomiting caused by chemotherapy, radiotherapy and postoperative treatment. The challenge with the OND API is its pH-dependent solubility and relatively short elimination half-life. Therefore, investigations were made to solve these problems in the current study. Formulations were prepared using stearic acid as a binding agent via a melt granulation process in a twin-screw extruder. The micro-environmental pH of the tablet was manipulated by the addition of fumaric acid to enhance the solubility and release of OND from the tablet. The in vitro release study demonstrated sustained release for 24h with 90% of drug release in formulations using stearic acid in combination with ethyl cellulose, whereas 100% drug release in 8h for stearic acid-hydroxypropylcellulose matrices. The formulation release kinetics was correlated to the Higuchi diffusion model and a non-Fickian drug release mechanism. The results of the present study demonstrated for the first time the pH dependent release from hydrophilic-lipid matrices as well as pH independent release from hydrophobic-lipid matrices for OND SR tablets manufactured by means of a continuous melt granulation technique utilizing a twin-screw extruder.

This study examined stressful life events and other predictors associated with remission from DSM-IV drug dependence involving cannabis, cocaine, hallucinogens, heroin, inhalants, non-heroin opioids, sedatives, stimulants, tranquilizers, or other drugs. Waves 1 and 2 of the National Epidemiologic Survey on Alcohol and Related Conditions were used to examine the prevalence and predictors of past-year remission status. Among U.S. adults with previous (i.e., prior-to-past-year) drug dependence (n = 921) at baseline (Wave 1), the prevalence of past-year remission status at Wave 1 was: abstinence (60.5%), asymptomatic drug use (18.8%), partial remission (7.1%), and still drug dependent (13.5%). Similarly, the prevalence of past-year remission status three years after baseline at Wave 2 was: abstinence (69.1%), asymptomatic drug use (15.5%), partial remission (8.4%), and still drug dependent (7.0%). Remission three years after baseline at Wave 2 was much more likely among formerly drug dependent U.S. adults who abstained from drug use at baseline (Wave 1) relative to those who reported asymptomatic drug use, partial remission, or remained drug dependent. Design-based weighted multinomial logistic regression analysis showed that relative to abstinence, past-year stressful events at baseline (Wave 1) predicted higher odds of partial remission and drug dependence at both Waves 1 and 2. This is the first national study to examine the potential role of stressful life events associated with remission from drug dependence. Although the majority of those who reported previous drug dependence transitioned to full remission, a sizeable percentage were either still drug dependent or in partial remission. Higher levels of stressful life events appear to create barriers for remission and should remain a focus for relapse prevention programs. PMID:27776676
Who Are the Subjects with Gambling-Related Problems Requiring Treatment? A Study in Northern Italy
Fioritti, Angelo; Marani, Silvia; Gambini, Daniele; Turino, Elsa; Piazza, Antonella
2018-01-01
Background: This study analyzes data related to Hospital (HOS), Public Treatment Service Dedicated to Drug Addicts (SERD), or Community Mental Health Center (CMHC) clients with a first diagnosis of Pathological Gambling (PG) in the period 2000/2016 in Northern Italy. The aims were to describe trends and characteristics of pathological gamblers (PGs) and to estimate the prevalence of other diagnoses before or after the diagnosis of PG. Methods: Participants aged over 17 years with an ICD-9 or ICD-10 PG diagnosis were selected. Results: 680 PGs were identified, mean age 47.4 years, 20% female, 13% non-natives, 30% had other mental disorders diagnoses, 9% had alcohol dependence syndrome, and 11% had drug dependence. Most participants with comorbid disorders were diagnosed before PG, with a more elevated prevalence regarding mental disorders. Almost seven years had elapsed on average between the first admission and the diagnosis of PG. Conclusions: The results of this study highlight a growing demand for PG treatment addressed not only to SERD, but also to psychiatric and hospital services, based on the increase in SERD attendance from 2013. Many of them had already been treated for mental health problems before, but their percentage remained costant over time. PMID:29652821
Clinical trials as treatment option: bioethics and health care disparities in substance dependency.
Timmermans, Stefan; McKay, Tara
2009-12-01
Bioethicists have warned against the dangers of mixing research with treatment. They are concerned that research priorities may take precedence over individual patient needs and that research subjects tend to misunderstand the purpose of research or overestimate the direct medical benefits of participating in studies. Yet, other work has questioned whether clinical research can always be separated from therapeutic benefit for participants. Using in-depth interviews with participants in two phase III randomized U.S. clinical trials for methamphetamine dependency, we examine the treatment options available to participants, their experiences with participating in the trials, and potential problems of trial participation. We find that while participants have experience with four alternative treatment modalities - quitting alone, support groups, in-patient treatment facilities, and consulting primary care physicians - the randomized clinical trials compare favorably to alternatives because they provide access to evidence-based behavioral treatments, specialized medical professionals, non-judgmental staff, and the possibility of receiving an experimental drug. We conclude that while randomized clinical trials are imperfect substitutes for clinical care, they constitute a fragile and sporadic therapeutic niche in a country with fundamental problems in access to health care, a mixed punitive-therapeutic drug addiction policy, and a profit-driven pharmaceutical development and approval process.
Dramatic decreases in brain reward function during nicotine withdrawal.
Epping-Jordan, M P; Watkins, S S; Koob, G F; Markou, A
1998-05-07
Tobacco smoking is a worldwide public health problem. In the United States alone, over 400,000 deaths and $50 billion in medical costs annually are directly attributed to smoking. Accumulated evidence indicates that nicotine is the component of tobacco smoke that leads to addiction, but the means by which nicotine produces addiction remain unclear. Nicotine is less effective as a positive reinforcer than other drugs of abuse in non-dependent animals. Nevertheless, nicotine-withdrawal symptoms, including depressed mood, anxiety, irritability and craving in dependent subjects may contribute to the addictive liability of nicotine. We show here that spontaneous nicotine withdrawal in rats resulted in a significant decrease in brain reward function, as measured by elevations in brain reward thresholds, which persisted for four days. Further, systemic injections of a competitive nicotinic-receptor antagonist led to a dose-dependent increase in brain reward thresholds in chronic nicotine-treated rats. The decreased function in brain reward systems during nicotine withdrawal is comparable in magnitude and duration to that of other major drugs of abuse, and may constitute an important motivational factor that contributes to craving, relapse and continued tobacco consumption in humans.

Bacterial antibiotic resistance is an emerging public health problem worldwide; therefore, new therapeutic strategies are needed. Many studies have described antipsychotic compounds that present antibacterial activity. Hence, the aims of this study were to evaluate the in vitro antibacterial activity of antipsychotics belonging to different chemical families, to assess the influence of their association with lipid nanocapsules (LNCs) on their antimicrobial activity as well as drug release and to study the uptake of LNCs by bacterial cells. Antibacterial activity was evaluated against Gram-positive Staphylococcus aureus and Gram negative Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae and Acinetobacter baumannii by minimum inhibitory concentration (MIC) assay, and the capability of killing tested microorganisms was evaluated by time kill assay. LNCs were prepared by phase inversion method, and the antipsychotic agents were incorporated using pre-loading and post-loading strategies. Only phenothiazines and thioxanthenes showed antibacterial activity, which was independent of antibiotic-resistance patterns. Loading the nanocarriers with the drugs affected the properties of the former, particularly their zeta potential. The release rate depended on the drug and its concentration-a maximum of released drug of less than 40% over 24 hours was observed for promazine. The influence of the drug associations on the antibacterial properties was concentration-dependent since, at low concentrations (high nanocarrier/drug ratio), the activity was lost, probably due to the high affinity of the drug to nanocarriers and slow release rate, whereas at higher concentrations, the activity was well maintained for the majority of the drugs. Chlorpromazine and thioridazine increased the uptake of the LNCs by bacteria compared with blank LNCs, even below the minimum inhibitory concentration.

Drug dependence is a recognized medical condition and therefore, right to health applies in the same way to drug dependence as it does to any other health condition. The human rights in patient care framework - which refers to the application of basic human rights principles in the delivery of health care services - was used to explore the experiences of equality in the dignity and rights protected by Polish law within four different specialist drug treatment settings in Poland. The views of patients and staff were examined and compared. Focus group interviews were conducted in 12 drug treatment facilities: three inpatient therapeutic communities, three outpatient programs, three opioid substitution programs and three harm reduction programs (drop-in/needle exchange/support). Interviews were conducted with a total of 43 staff and 73 patients. All interviews were audio-recorded with participants' prior consent and transcribed verbatim. Data were analysed according to the problem-centred interview methodology, using CAQDA. Patients described instances of abuse of their rights regarding dignity, privacy, confidentiality, personalized treatment, and respect of patient's time, right to information and to complain. Those accounts were complemented by the perspective of professionals working in drug treatment. Patients of Polish opioid substitution programs reported experiencing more humiliation and disenfranchisement than patients in other drug treatment settings. Drug testing and control, fuelled by prejudices of health professionals, are leading to discriminatory practices in substitution treatment and damaging the chances of therapeutic success. The concept of epistemic injustice illuminates the reasons behind discrimination against patients on opioid substitution programs, who are seen as continuously sick and their illness perceived as a mark of moral, social and epistemic failure.

Ghrelin is a recently isolated brain-gut peptide that has growth hormone-releasing and appetite-inducing activities. Several recent studies have suggested that ghrelin plays a major role in the pathophysiology of drug-seeking behavior and anxiety. Therefore, we assessed the effect of the ghrelin precursor polymorphism on methamphetamine dependence in the Korean population. One hundred and eighteen patients with methamphetamine dependence, according to the Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV) criteria, and the 144 healthy controls were enrolled in this study. Genotyping for the ghrelin precursor polymorphism was performed by the polymerase chain reaction-restriction fragment length polymorphism-based technique. The genotypic and allelic distributions of the ghrelin precursor polymorphism in the patients with methamphetamine dependence were not significantly different from those of the control subjects. However, the Met72 carriers were associated with the emotional problems of methamphetamine dependence. The patients with the Met72 allele were more depressed and anxious than the homozygous patients with the wild Leu72 allele. The present study suggests that the ghrelin precursor polymorphism may not confer a susceptibility to the development of methamphetamine dependence in the Korean population. However, the Leu72Met polymorphism could have a potential role in the emotional problems that are associated with this disease.

Marijuana: a decade and a half later, still a crude drug with underappreciated toxicity.
Schwartz, Richard H
2002-02-01
In 1984, I published in this journal a review entitled "Marijuana: A Crude Drug With a Spectrum of Underappreciated Toxicity." In the introduction to that article, I disclosed that our son Keith, who was 15 years old at the time, was in a long-term, modified outpatient adolescent drug and alcohol rehabilitation program because he had become dependent on marijuana with its associated behavioral, interpersonal, scholastic, and antisocial problems. Keith and most of his friends had experimented several times with LSD, beer, and several other drugs but never used injection drugs. Marijuana was clearly Keith's drug of choice and the only drug he used with regularity. Approximately 1 year later, Keith graduated from the treatment program. He completed the early aftercare component, relapsed several times, and completed a 4-month refresher drug rehabilitation program in another state. Nine years after admission to the first rehabilitation program, Keith finally attained some adult goals. Now 34 years old, he has been drug-free for 10 years. He is the president and owner of a successful discount cellular phone business that he started. More important, a decade ago, he reestablished an excellent and close relationship with his parents. As far as I can tell, Keith remains drug-free except for an occasional beer.

Purpose Examine the severity of club drug dependence and perceived need for treatment, and further identify their determinants among a sample of club drug users in Shanghai, China. Methods 276 club drug users were recruited using respondent-driven sampling (RDS). Severity of dependence on club drugs was measured using the Severity of Dependence Scale (SDS). Results 69.9% reported dependence on club drugs (i.e., SDS≥4) and 36.6% reported severe dependence (i.e., SDS≥6). One eighth (12.7%) perceived need for drug treatment. Severe dependence on club drugs was more likely among those who reported recent use of ecstasy and those who had more depressive symptoms, but less likely among those reporting recent use of methamphetamine. Perceived need for treatment was more likely among those who lived with a spouse or boy/girlfriend, but less likely among those had prior drug treatment experience and more severe club drug dependence. Conclusions Our findings suggest that educational activities should be implemented to raise public awareness about the powerful addictive properties of club drugs, along with efforts to reduce stigma towards drug abuse and psychiatric disorders. Programs to motivate drug users to seek treatment and encourage treatment linkage are urgently needed. PMID:23715971

Background Crack cocaine use undermines adherence to highly active antiretroviral therapy (HAART). This pilot randomized clinical trial tested the feasibility and efficacy of 2 interventions based on the Information-Motivation-Behavioral Skills model to improve HAART adherence and reduce crack cocaine problems. Methods Participants were 54 adults with crack cocaine use and HIV with <90% HAART adherence. Most participants were African-American (82%) heterosexual (59%), and crack cocaine dependent (92%). Average adherence was 58% in the past 2 weeks. Average viral loads (VL) were detectable (log VL 2.97). The interventions included 6 sessions of Motivational Interviewing plus feedback and skills building (MI+), or Video information plus debriefing (Video+) over 8 weeks. Primary outcomes were adherence by 14-day timeline follow-back and Addiction Severity Index (ASI) Drug Composite Scores at 3 and 6 months. Repeated measures ANOVA assessed main effects of the interventions and interactions by condition. Results Significant increases in adherence and reductions in ASI Drug Composite Scores occurred in both conditions by 3 months and were maintained at 6 months, representing medium effect sizes. No between group differences were observed. No VL changes were observed in either group. Treatment credibility, retention, and satisfaction were high and not different by condition. Conclusions A counseling and a video intervention both improved adherence and drug problems durably among people with crack cocaine use and poor adherence in this pilot study. The interventions should be tested further among drug users with poor adherence. Video interventions may be feasible and scalable for people with HIV and drug use. PMID:21306837

We report the development and implementation of an energy decomposition analysis (EDA) scheme in the ONETEP linear-scaling electronic structure package. Our approach is hybrid as it combines the localized molecular orbital EDA (Su, P.; Li, H. J. Chem. Phys., 2009, 131, 014102) and the absolutely localized molecular orbital EDA (Khaliullin, R. Z.; et al. J. Phys. Chem. A, 2007, 111, 8753-8765) to partition the intermolecular interaction energy into chemically distinct components (electrostatic, exchange, correlation, Pauli repulsion, polarization, and charge transfer). Limitations shared in EDA approaches such as the issue of basis set dependence in polarization and charge transfer are discussed, and a remedy to this problem is proposed that exploits the strictly localized property of the ONETEP orbitals. Our method is validated on a range of complexes with interactions relevant to drug design. We demonstrate the capabilities for large-scale calculations with our approach on complexes of thrombin with an inhibitor comprised of up to 4975 atoms. Given the capability of ONETEP for large-scale calculations, such as on entire proteins, we expect that our EDA scheme can be applied in a large range of biomolecular problems, especially in the context of drug design.

Incarcerated women have high rates of substance abuse problems and trauma. A variety of variables may influence whether these women seek help or are referred for substance abuse problems. This study reports an exploratory project on service utilization among incarcerated substance-dependent women (N = 40) in southeastern Idaho. Using self-report and interview tools, most participants reported some substance abuse treatment history, although extent and types of treatment varied. Most of the women also reported some type of childhood abuse. Age, income, and consequences of alcohol and other drug use related positively to substance abuse treatment. However, severity of childhood sexual abuse and current trauma symptoms were negatively correlated with substance abuse treatment episodes. These women may use substances to cope with childhood trauma or may not perceive the substance abuse system as responsive to their co-occurring trauma symptoms. Copyright © 2011 Elsevier Inc.

Recent reports suggest that anabolic-androgenic steroids (AAS) may cause mood disorders or dependence syndromes and may help to introduce some individuals to opioid abuse. At present, however, little is known about prior AAS use among men entering inpatient substance abuse treatment. We assessed lifetime AAS use in 223 male substance abusers admitted to a substance abuse treatment unit primarily for treatment of alcohol, cocaine, and opioid dependence. Subjects reporting definite or possible AAS use were then asked to participate in a detailed semistructured interview that covered demographics, drug use history, and symptoms experienced during AAS use and withdrawal, and whether AAS use had helped introduce the subject to other classes of drugs. Twenty-nine men (13%) reported prior AAS use, but this history was documented on physicians' admission evaluations in only 4 cases. Among 88 men listing opioids as their drug of choice, 22 (25%) acknowledged AAS use, versus only 7 (5%) of the other 135 men (p <.001). Twenty-four (83%) of the 29 AAS users were interviewed in detail. Seven (29%) of the men interviewed, all with opioid dependence, reported that they first learned about opioids from friends at the gym and subsequently first obtained opioids from the same person who had sold them AAS. Eighteen (75%) of the men interviewed reported that AAS were the first drugs that they had ever self-administered by injection, 4 (17%) reported severe aggressiveness or violence during AAS use, 1 (4%) attempted suicide during AAS withdrawal, and 5 (21%) described a history of AAS dependence. Prior AAS use appears to be common but underrecognized among men entering inpatient substance abuse treatment, especially those with opioid dependence. AAS use may serve as a "gateway" to opioid abuse in some cases and may also cause morbidity in its own right.
Applicability of Type A/B alcohol dependence in the general population.

This study examined the concurrent and predictive validity of Type A/B alcohol dependence in the general population-a typology developed in clinical populations to gauge severity of dependence. Data were drawn from Waves 1 and 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). The sample included 1,172 alcohol-dependent drinkers at baseline who were reinterviewed three years later. Latent class analysis was used to derive Type A/B classification using variables replicating the original Type A/B typology. Predictive validity of the Type A/B classification was assessed by multivariable linear and logistic regressions. A two-class solution consistent with Babor's original Type A/B typology adequately fit the data. Type B alcoholics in the general population, compared to Type As, had higher alcohol severity and more co-occurring drug, mental, and physical health problems. In the absence of treatment services utilization, Type B drinkers had two times the odds of being alcohol dependent three years later. Among those who utilized alcohol treatment services, Type B membership was predictive of heavy drinking and drug dependence, but not alcohol dependence, three years later. Findings suggest that Type A/B classification is both generalizable to, and valid within, the US general population of alcohol dependent drinkers. Results highlight the value of treatment for mitigating the persistence of dependence among Type B alcoholics in the general population. Screening for markers of vulnerability to Type B dependence could be of clinical value for health care providers to determine appropriate intervention. Copyright © 2014 Elsevier Ireland Ltd.

The purpose of each dosage form is to provide an optimal therapeutic effect with a minimum dose and with minimal side effects. This is particularly relevant for drugs that require systemic administration, higher dosing and/or show lower bioavailability. Тhe eye as an anatomical structure is an extremely protected organ. In this regard, providing an optimal bioavailability in the eye tissues, resulting in the desired therapeutic effect represents a major challenge. This is especially true for the treatment of diseases, affecting the posterior segment after topically administered drug formulations. The use of nano- and microcarriers of drug substances may be an appropriate technological approach, to provide a high bioavailability of the drug substance for a certain interval of time at the right place. The purpose of this review is to indicate how nano- and microcarriers of drug substances can solve the problems with the drug delivery in the ocular tissues, to indicate the possible hazards and side effects, depending on the polymer nature and route of administration, and to visualize the future potential of these carriers in the pharmaceutical practice.

Bioequivalence studies of drugs prescribed mainly for women.
McGilveray, Iain J
2011-01-01
The basic components of pharmacokinetics are absorption, distribution, metabolism, and excretion. During pregnancy there may be changes in one or many of these components. Early drug studies did not include a representative proportion of women, however, researchers as well as regulators agree that studies on the sex differences in the disposition of drugs are important, but at what stage in the clinical trial process? Except for drugs used only in women, such as those for estrogen-dependent breast cancer, caution prevails and the differences are usually studied at phase 3. Studies in pregnant women are much rarer but some do get done, e.g., with antivirals and antimalarials, where the positive risk-benefit of these agents is the likelihood that fetal transfer of these drugs might help protect the fetus. Women are being included in pharmacokinetic studies for new drug applications in accordance with the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH), U.S. Food and Drug Administration (FDA), and Health Canada (HC) guidances. A new look at bioequivalence studies, to compare results in men and women, would help determine if interactions of formulation and gender are a problem.
Extracting sets of chemical substructures and protein domains governing drug-target interactions.

The identification of rules governing molecular recognition between drug chemical substructures and protein functional sites is a challenging issue at many stages of the drug development process. In this paper we develop a novel method to extract sets of drug chemical substructures and protein domains that govern drug-target interactions on a genome-wide scale. This is made possible using sparse canonical correspondence analysis (SCCA) for analyzing drug substructure profiles and protein domain profiles simultaneously. The method does not depend on the availability of protein 3D structures. From a data set of known drug-target interactions including enzymes, ion channels, G protein-coupled receptors, and nuclear receptors, we extract a set of chemical substructures shared by drugs able to bind to a set of protein domains. These two sets of extracted chemical substructures and protein domains form components that can be further exploited in a drug discovery process. This approach successfully clusters protein domains that may be evolutionary unrelated but that bind a common set of chemical substructures. As shown in several examples, it can also be very helpful for predicting new protein-ligand interactions and addressing the problem of ligand specificity. The proposed method constitutes a contribution to the recent field of chemogenomics that aims to connect the chemical space with the biological space.
Legislations combating counterfeit drugs in Hong Kong.
Lai, C W; Chan, W K
2013-08-01
To understand legislation combating counterfeit drugs in Hong Kong. This study consisted of two parts. In part I, counterfeit drugs–related ordinances and court cases were reviewed. In part II, indepth interviews of the stakeholders were described. Hong Kong. All Hong Kong ordinances were screened manually to identify those combating counterfeit drugs. Court cases were searched for each of the identified cases. Then, the relevant judgement justifications were analysed to identify sentencing issues. Indepth interviews with the stakeholders were conducted to understand their perceptions about such legislation. Trade Marks Ordinance, Patents Ordinance, Trade Descriptions Ordinance, and Pharmacy and Poisons Ordinance were current legislative items combating counterfeit drugs. Sentencing criteria depended on: intention to deceive, quantity of seized drugs, presence of expected therapeutic effect or toxic ingredients, previous criminal records, cooperativeness with Customs officers, honest confessions, pleas of guilty, types of drugs, and precautionary measures to prevent sale of counterfeit drugs. Stakeholders’ perceptions were explored with respect to legislation regarding the scale and significance of the counterfeit drug problem, penalties and deterrents, drug-specific legislation and authority, and inspections and enforcement. To plug the loopholes, a specific law with heavy penalties should be adopted. This could be supplemented by non-legal measures like education of judges, lawyers, and the public; publishing the names of offending pharmacies; and emphasising the role of pharmacists to the public.

An all-embracing problem description. The Swedish drug issue as a political catalyst 1982-2000.
Edman, Johan
2013-11-01
This article examines the political formulation and ideological solution of the Swedish drug problem in 1982-2000. How was the drug problem described in the Swedish parliament at the time? How serious was the problem and what solutions were proposed? What were the ideological implications of the problem description, and how was the general political and ideological solution formulated? The empirical basis for the textual analysis consists of parliamentary bills, government bills and parliamentary records discussing the drug issue during the years 1982-2000. In the prevailing spirit of consensus in the Swedish parliament at the time, both left-wing and right-wing parties portrayed drugs as a threat to the nation, people and the welfare state. Still, as the ideological dimension kept growing stronger, the drug question functioned even better as an arena for political discussions and ideological positions than in the 1970s. Compared to previous decades, the problem description broadened during the 1980s and 1990s, and the drug problem could be used to support arguments on almost any topic. The drug problem became a highly politicized issue about whom or what to change when the individual and the society clashed, but also about what the individual and/or society should be changed into.

Interrogative suggestibility in opiate users.
Murakami, A; Edelmann, R J; Davis, P E
1996-09-01
The present study investigated interrogative suggestibility in opiate users. A group of patients undergoing a methadone detoxification programme in an in-patient drug treatment unit (Detox group, n = 21), and a group of residents who had come off drugs and were no longer suffering from withdrawal syndrome (Rehab group, n = 19) were compared on interrogative suggestibility and various other psychological factors. Significant differences were found between the two groups, with the Detox group having more physical and psychological problems, and a higher total suggestibility score in comparison with the Rehab group. These findings are discussed in relation to the context of police interrogations and the reliability of confessions made by suspects and witnesses dependent on opiates.

Cocaine dependence is a significant public health problem for which there are currently no FDA-approved medications. Hence, identifying candidate compounds and employing an efficient evaluation process is crucial. This paper describes key design decisions made for a National Institute on Drug Abuse (NIDA) Clinical Trials Network (CTN) study that uses a novel two-stage process to evaluate buspirone (60 mg/day) for cocaine-relapse prevention. The study includes pilot (N=60) and full-scale (estimated N=264) trials. Both trials will be randomized, double-blind, and placebo-controlled and both will enroll treatment-seeking cocaine-dependent participants engaged in inpatient/residential treatment and scheduled for outpatient treatment post-discharge. All participants will receive contingency management in which incentives are given for medication adherence as evaluated by the Medication Events Monitoring System (MEMS). The primary outcome measure is maximum days of continuous cocaine abstinence, as assessed by twice-weekly urine drug screens (UDS) and self-report, during the 15-week outpatient treatment phase. Drug-abuse outcomes include cocaine use as assessed by UDS and self-report of cocaine use, other substance use as assessed by UDS and self-report of substance use (i.e., alcohol and/or illicit drugs), cocaine bingeing, HIV risk behavior, quality of life, functioning, and substance-abuse treatment attendance. Unique aspects of the study include conducting an efficacy trial in community treatment programs, a two-stage process to efficiently evaluate buspirone, and an evaluation of mediators by which buspirone might exert a beneficial effect on relapse prevention.

Energy drink consumption and increased risk for alcohol dependence
Arria, Amelia M.; Caldeira, Kimberly M.; Kasperski, Sarah J.; Vincent, Kathryn B.; Griffiths, Roland R.; O'Grady, Kevin E.
2010-01-01
Background Energy drinks are highly caffeinated beverages that are increasingly consumed by young adults. Prior research has established associations between energy drink use and heavier drinking and alcohol-related problems among college students. This study investigated the extent to which energy drink use might pose additional risk for alcohol dependence over and above that from known risk factors. Methods Data were collected via personal interview from 1,097 fourth-year college students sampled from one large public university as part of an ongoing longitudinal study. Alcohol dependence was measured with DSM-IV criteria. Results After adjustment for the sampling design, 51.3%wt of students were classified as “low-frequency” energy drink users (1 to 51 days in the past year) and 10.1%wt as “high-frequency” users (≥52 days). Typical caffeine consumption varied widely depending on the brand consumed. Compared to the low-frequency group, high-frequency users drank alcohol more frequently (141.6 vs. 103.1 days) and in higher quantities (6.15 vs. 4.64 drinks/typical drinking day). High-frequency users were at significantly greater risk for alcohol dependence relative to both non-users (AOR=2.40, 95% CI=1.27-4.56, p=.007) and low-frequency users (AOR=1.86, 95% CI=1.10, 3.14, p=.020), even after holding constant demographics, typical alcohol consumption, fraternity/sorority involvement, depressive symptoms, parental history of alcohol/drug problems, and childhood conduct problems. Low-frequency energy drink users did not differ from non-users on their risk for alcohol dependence. Conclusions Weekly or daily energy drink consumption is strongly associated with alcohol dependence. Further research is warranted to understand the possible mechanisms underlying this association. College students who frequently consume energy drinks represent an important target population for alcohol prevention. PMID:21073486
Working memory subsystems are impaired in chronic drug dependents.
Soliman, Abdrabo Moghazy; Gadelrab, Hesham Fathy; Elfar, Rania Mohamed
2013-06-01
A large body of research that has investigated substance dependence and working memory (WM) resources, yet no prior study has used a comprehensive test battery to examine the impact of chronic drug dependence on WM as a multi-component system. This study examined the efficiency of several WM components in participants who were chronic drug dependents. In addition, the functioning of the four WM components was compared among dependents of various types of drugs. In total, 128 chronic drug dependents participated in this study. Their average age was 38.48 years, and they were classified into four drug-dependence groups. Chronic drug dependents were compared with a 36-participant control group that had a mean age of 37.6 years. A WM test battery that comprised eight tests and that assessed each of four WM components was administered to each participant. Compared with the control group, all four groups of drug dependents had significantly poorer test performance on all of the WM tasks. Among the four groups of drug users, the polydrug group had the poorest performance scores on each of the eight tasks, and the performance scores of the marijuana group were the least affected. Finally, the forward digit span task and the logical memory tasks were less sensitive than other tasks when differentiating between marijuana users and the normal participants. The four components of WM are impaired among chronic drug dependents. These results have implications for the development of tools, classification methods and therapeutic strategies for drug dependents.

Alginate vehicles are capable of forming a gel matrix in situ when they come into contact with gastric medium in the presence of calcium ions. However, the gel structure is pH dependent and can break after gastric emptying, leading to dose dumping. The aim of this work was to develop modified in situ gelling alginate formulations capable of sustaining dextromethorphan release throughout the gastrointestinal tract. Alginate solution (2 %, m/m) was used as a vehicle for the tested formulations. Solid matrix of the drug and Eudragit S 100 was prepared by dissolving the drug and polymer in acetone. The organic solvent was then evaporated and the deposited solid matrix was micronized, sieved and dispersed in alginate solution to obtain candidate formulations. The release behavior of dextromethorphan was monitored and evaluated in a medium simulating the gastric and intestinal pH. Drug-polymer compatibility and possible solid-state interactions suggested physical interaction through hydrogen bonding between the drug and the polymer. A significant decrease in the rate and extent of dextromethorphan release was observed with increasing Eudragit S 100 concentration in the prepared particles. Most formulations showed sustained release profiles similar to that of a commercial sustained-release liquid based on ion exchange resin. The release pattern indicated strict control of drug release both under gastric and intestinal conditions, suggesting the potential advantage of using a solid dispersion of drug-Eudragit S 100 to overcome the problem of dose dumping after the rupture of the pH dependent alginate gels.
ABM Clinical Protocol #21: Guidelines for Breastfeeding and the Drug-Dependent Woman
2009-01-01
A central goal of The Academy of Breastfeeding Medicine is the development of clinical protocols for managing common medical problems that may impact breastfeeding success. These protocols serve only as guidelines for the care of breastfeeding mothers and infants and do not delineate an exclusive course of treatment or serve as standards of medical care. Variations in treatment may be appropriate according to the needs of an individual patient. PMID:19835481
Outreach pharmacy service in old age homes: a Hong Kong experience.
Lau, Wai-Man; Chan, Kit; Yung, Tsz-Ho; Lee, Anna See-Wing
2003-06-01
To explore drug-related problems in old age homes in Hong Kong through outreach pharmacy service. A standard form was used by outreach pharmacists to identify drug-related problems at old age homes. Homes were selected through random sampling, voluntary participation or adverse selection. Initial observation and assessment were performed in the first and second weeks. Appropriate advice and recommendations were given upon assessment and supplemented by a written report. Educational talks were provided to staff of the homes in addition to other drug information materials. At week 7 to 9, evaluations were carried out. Eighty-five homes were assessed and identified to have problems in the drug management system. These problems could generally be classified into physical storage (8.8%), quality of storage (19.2%), drug administration system (13.3%), documentation (16.4%), and drug knowledge of staff of homes (42.2%). Quality of drug storage was the most common problem found, followed by documentation and drug knowledge (73%, 50% and 44% of points assessed with problems, respectively). Apart from lack of drug knowledge and unawareness of potential risks by staff, minimal professional standards unmet may be fundamentally related to lack of professional input and inadequacy in legislation. Most homes demonstrated significant improvements upon simple interventions, from a majority of homes with more than 10 problems to a majority with less than 5 problems. Diverse problems in drug management are common in old age homes, which warrants attention and professional inputs. Simple interventions and education by pharmacists are shown to be effective in improving the quality of drug management and hence care to residents. While future financing of old age home service can be reviewed within the social context to provide incentives for improvement, review of regulatory policy with enforcement may be more fundamental and effective in upholding the service standard.
Naltrexone implant treatment for buprenorphine dependence--Mauritian case series.
Jhugroo, Anil; Ellayah, Darmen; Norman, Amanda; Hulse, Gary
2014-08-01
Although substitution therapy with opiate agonist treatments such as methadone and buprenorphine has resulted in a reduction of illicit drug use related harm, such treatment has also resulted in severe problems in some countries where opioid-dependent individuals now inject illicitly sold buprenorphine or buprenorphine-naloxone instead of heroin. There is no approved treatment for buprenorphine dependence. Naltrexone is an opioid antagonist which has been used for the treatment of both alcohol and opioid dependencies. Although both buprenorphine and heroin resemble each other concerning their effects, buprenorphine has a higher affinity to opioid receptors than heroin. Therefore, it is not known if naltrexone can block the psychoactive effects of buprenorphine as it does for heroin. This paper presents observational case series data on the use of a sustained-release naltrexone implant for the treatment of buprenorphine dependence. To the authors' knowledge this is the first use of sustained-release naltrexone for this indication. © The Author(s) 2014.

Background HIV risks for women who inject drugs and those who engage in sex work are well documented. Women who are dependent on non-injecting drugs and alcohol are also likely to have increased vulnerability to HIV infection, but until they actually inject drugs or engage in sex work, are unlikely to come to the attention of HIV prevention programs. Methods We undertook a qualitative study involving nine focus group discussions (FGDs) and 27 key informant interviews to investigate the context of female drug and alcohol use in two high HIV prevalence states of India (Manipur and Nagaland) and to describe their HIV risks. The FGD and interview transcripts were thematically analyzed Results The women were relatively young (mean age 31 years in Manipur and 28 years in Nagaland), but 64% in Manipur and 35% in Nagaland were widowed or divorced. Both heroin and alcohol were commonly used by the women from Manipur, while alcohol was primarily used by the women from Nagaland, especially in the context of ‘booze joints’ (illicit bars). Reasons for drug and alcohol use included: to avoid symptoms of withdrawal, to suppress emotional pain, to overcome the shame of sex work, pleasure, and widowhood. HIV vulnerability was clearly described, not only in relation to injecting drug use and sex work, but also alcohol consumption. Conclusions The contribution of alcohol use to the HIV vulnerability of women is not currently considered when HIV prevention programs are being designed and implemented leaving a group of high-risk women uncovered by much needed services such as treatment for a range of health problems including alcohol dependence.

Predicting activity approach based on new atoms similarity kernel function.
Abu El-Atta, Ahmed H; Moussa, M I; Hassanien, Aboul Ella
2015-07-01
Drug design is a high cost and long term process. To reduce time and costs for drugs discoveries, new techniques are needed. Chemoinformatics field implements the informational techniques and computer science like machine learning and graph theory to discover the chemical compounds properties, such as toxicity or biological activity. This is done through analyzing their molecular structure (molecular graph). To overcome this problem there is an increasing need for algorithms to analyze and classify graph data to predict the activity of molecules. Kernels methods provide a powerful framework which combines machine learning with graph theory techniques. These kernels methods have led to impressive performance results in many several chemoinformatics problems like biological activity prediction. This paper presents a new approach based on kernel functions to solve activity prediction problem for chemical compounds. First we encode all atoms depending on their neighbors then we use these codes to find a relationship between those atoms each other. Then we use relation between different atoms to find similarity between chemical compounds. The proposed approach was compared with many other classification methods and the results show competitive accuracy with these methods. Copyright © 2015 Elsevier Inc. All rights reserved.
Subcutaneous drug infusions: a review of problems and solutions.
Mitten, T
2001-02-01
Subcutaneous drug infusion using a portable syringe driver has had a significant impact on patient comfort in palliative care. It permits the continuous delivery of a range of drug therapies, so bypassing problems of dysphagia, weakness and the inability of many patients in the terminal phase to take oral medication. The devices are not problem-free, however. Mechanical problems, reactions at the infusion site and difficulties with the mixing of drugs in the syringe are all widely recognized. This article reviews some general issues with the operation of portable syringe drivers, and discusses a range of potential problems and their solutions.

Substance abuse disorders in nurses.
Griffith, J
1999-01-01
Substance abuse is a serious concern in the profession of nursing. The American Nurses Association (1997) estimates that 10% to 20% of nurses have substance abuse problems, and that 6% to 8% of registered nurses are impaired due to their abuse of alcohol and other drugs. Chemical dependency is considered a disease that requires treatment. Early identification and treatment of the chemically dependent nurse is important for the safety of the public and for the well-being of the nurse and her profession. This article addresses substance abuse from a biopsychosocial perspective, and includes a description of an approach to treatment and suggestions for the role of nursing administration.

The enhanced permeability and retention (EPR) effect of solid tumors as seen with nanomedicines and macromolecular drugs is well known. However, many researchers appear to lack a full understanding of this effect. The effect varies depending on a patient's pathological and physiological characteristics and clinical condition. When a patient's systolic blood pressure is low side of about 90mmHg instead of 120-130mmHg, the hydrodynamic force pushing blood from the luminal side of a vessel into tumor tissue becomes significantly low, which results in a low EPR. Also, a vascular embolism in a tumor may impede blood flow and the EPR. Here, I describe the background of the EPR effect, heterogeneity of this effect, physiological and pathological factors affecting the effect, the EPR effect in metastatic tumors, artifacts of the EPR effect with micellar and liposomal drugs, problems of macromolecular drug stability and drug release, and access to target sites.

Current therapies for human parasite infections rely on a few drugs, most of which have severe side effects, and their helpfulness is being seriously compromised by the drug resistance problem. Globally, this is pushing discovery research of antiparasitic drugs toward new agents endowed with new mechanisms of action. By using a "drug repurposing" strategy, histone deacetylase inhibitors (HDACi), which are presently clinically approved for cancer use, are now under investigation for various parasite infections. Because parasitic Zn 2+ - and NAD + -dependent HDACs play crucial roles in the modulation of parasite gene expression and many of them are pro-survival for several parasites under various conditions, they are now emerging as novel potential antiparasitic targets. This Perspective summarizes the state of knowledge of HDACi (both class I/II HDACi and sirtuin inhibitors) targeted to the main human parasitic diseases (schistosomiasis, malaria, trypanosomiasis, leishmaniasis, and toxoplasmosis) and provides visions into the main issues that challenge their development as antiparasitic agents.

Accumulating evidence suggests the endocannabinoid system modulates environmental cues' ability to induce seeking of drugs, including nicotine and alcohol. However, little attention has been directed toward extending these advances to the growing problem of cannabis use disorders. Therefore, we studied intravenous self-administration of Delta(9)-tetrahydrocannabinol (THC), the main psychoactive constituent of marijuana, using a second-order schedule of drug seeking. Squirrel monkeys' lever responses produced only a brief cue light until the end of the session, when the final response delivered THC along with the cue. When a reinstatement procedure was used to model relapse following a period of abstinence, THC-seeking behavior was robustly reinstated by the cue or by pre-session administration of THC, other cannabinoid agonists, or morphine, but not cocaine. The cannabinoid antagonist rimonabant blocked cue-induced drug seeking, THC-induced drug seeking, and the direct reinforcing effects of THC. Thus, rimonabant and related medications might be effective as treatments for cannabinoid dependence.

Data were obtained on four dimensions of criminal activity (frequency, variety, severity, and income) from male and female prisoners (N = 200) with preincarceration heroin dependence who participated in a randomized clinical trial of buprenorphine treatment. The article examines the above-mentioned dimensions of crime and their relationships with demographic characteristics, substance use, legitimate employment, drug treatment episodes, and psychological problems. Results largely show several important similarities to results on previous prison inmate cohorts with histories of heroin addiction, although the present sample may have more of a tendency toward violent crime than earlier cohorts of heroin-dependent offenders. This study’s findings may have implications for the design of appropriate treatment interventions for prisoners with preincarceration heroin dependence that address not only substance use but also criminal activity.

[Adverse reactions and other drug-related problems in an emergency service department].
Güemes Artiles, M; Sanz Alvarez, E; Garcia Sánchez-Colomer, M
1999-01-01
Adverse Drug Reactions (ADR) and Drug-Related Problems (DRP's) are a frequency cause of hospital emergency room visits and require better assessment. An analysis was made of 1097 consecutive admission to the emergency room at the Nuestra Senora de los Volcanes, Hospital (currently the General Hospital of Lanzarote) in Arrecife de Lanzarote (Canary Islands) over a three-month period in order to detect any possible DAR or any other drug-related problems. Nineteen (19) of the 1097 admissions were due to Adverse Drug Reactions (ADR) (1.73%; 95% IC:0.96%-2.5%). Some of the most outstanding of the other "Drug-Related Problems" (DRP's) were medication overdose, which was diagnosed in 5 (0.45%) of the patients; the worsening of the symptoms due to ceasing to take the medication was involved in 8 (0.72%), and incorrect treatments which involved medical care at the emergency room totaled 11 (1.0%). The number of drug-related problems (DRP's) in the sample totaled 43 (3.9%). The drug-related problems (DRP's) led to hospitalization in 1.9% of the cases seen in the emergency room and led to hospitalization in 9.6% of all of hospital admission through the emergency room for the period of time under study. The ADR led to 4.1% of the hospital admissions. Drug-related problems are a frequent, major problem which has not been well-analyzed in the emergency rooms. Additionally, emergency rooms can function as the first point of detection of a ADR among an outpatient population.

For decades, mass spectrometry data has been analyzed to investigate a wide array of research interests, including disease diagnostics, biological and chemical theory, genomics, and drug development. Progress towards solving any of these disparate problems depends upon overcoming the common challenge of interpreting the large data sets generated. Despite interim successes, many data interpretation problems in mass spectrometry are still challenging. Further, though these challenges are inherently interdisciplinary in nature, the significant domain-specific knowledge gap between disciplines makes interdisciplinary contributions difficult. This paper provides an introduction to the burgeoning field of computational mass spectrometry. We illustrate key concepts, vocabulary, and open problems in MS-omics, as well as provide invaluable resources such as open data sets and key search terms and references. This paper will facilitate contributions from mathematicians, computer scientists, and statisticians to MS-omics that will fundamentally improve results over existing approaches and inform novel algorithmic solutions to open problems.
[Special considerations in generic substitution of immunosuppressive drugs in transplantation].
Remport, Adám; Dankó, Dávid; Gerlei, Zsuzsa; Czebe, Krisztina; Kiss, István
2012-08-26
Long-term success in solid organ transplantation strongly depends on the optimal use of maintenance immunosuppressive treatment. Cyclosporin and tacrolimus are the most frequently administered immunosuppressants and they are designed to narrow therapeutic index drugs. The substitution of the branded formulation by their generic counterparts may lead to economic benefit only if equivalent clinical outcomes can be achieved. There is no published evidence to date on the guarantee of their long-term therapeutic equivalence and cases of therapeutic failures have been reported due to inadvertent drug conversion. The disadvantageous clinical consequences of a non medical, mechanistic forced switch from the original to generic formulation of tacrolimus and the estimated loss of the payer's presumed savings are presented in a kidney transplant recipient population. Special problems related to pediatric patients, drug interactions with concurrent medications and the burden of additional therapeutic drug monitoring and follow up visits are also discussed. The authors are convinced that the implementation of the European Society of Organ Transplantation guidelines on generic substitution may provide a safe way for patients and healthcare payers.
Measurements of Deposition, Lung Surface Area and Lung Fluid for Simulation of Inhaled Compounds.
Fröhlich, Eleonore; Mercuri, Annalisa; Wu, Shengqian; Salar-Behzadi, Sharareh
2016-01-01
Modern strategies in drug development employ in silico techniques in the design of compounds as well as estimations of pharmacokinetics, pharmacodynamics and toxicity parameters. The quality of the results depends on software algorithm, data library and input data. Compared to simulations of absorption, distribution, metabolism, excretion, and toxicity of oral drug compounds, relatively few studies report predictions of pharmacokinetics and pharmacodynamics of inhaled substances. For calculation of the drug concentration at the absorption site, the pulmonary epithelium, physiological parameters such as lung surface and distribution volume (lung lining fluid) have to be known. These parameters can only be determined by invasive techniques and by postmortem studies. Very different values have been reported in the literature. This review addresses the state of software programs for simulation of orally inhaled substances and focuses on problems in the determination of particle deposition, lung surface and of lung lining fluid. The different surface areas for deposition and for drug absorption are difficult to include directly into the simulations. As drug levels are influenced by multiple parameters the role of single parameters in the simulations cannot be identified easily.

Drugs have been in the past and will in the future still be liable to induce apnea in neonates, infants and older children. At these different stages of development, the child may be abnormally vulnerable to respiratory disorders and apnea, and doses of drugs, without any abnormal side effects in adult patients, can be harmful in younger subjects. Drugs responsible for apnea during development are numerous, but more than half of the problems are induced by sedatives and hypnotics, among which phenothiazines, barbiturates, benzodiazepines (included transplacentally acquired) and general anesthetics are a few. Other pharmacological families are apnea inducers in the neonatal period and childhood: analgesics and opioid narcotics, agents acting at the levels of neuromuscular function and autonomic ganglia, and cardiovascular agents. The pathogenesis of these apneas depends on the disturbance of any mechanism responsible for the respiratory activity: medullary centers and brain stem structures, afferent influx to CNS, sleep stages, upper airways, lungs and respiratory muscles. At key stages such as birth and infancy, drugs may emphasize the particular sensitivity of the mechanisms responsible for inducing apnea. This might explain unexpected respiratory disorders during development.

To describe drug-related problems identified in hospitalized patients and to assess physicians' acceptance rate of pharmacists' recommendations. Retrospective observational study that included all drug-related problems detected in hospitalized patients during 2014-2015. Statistical analysis included a descriptive analysis of the data and a multivariate logistic regression to evaluate the association between pharmacists' recommendation acceptance rate and the variable of interest. During the study period 4587 drug-related problems were identified in 44,870 hospitalized patients. Main drug-related problems were prescription errors due to incorrect use of the computerized physician order entry (18.1%), inappropriate drug-drug combination (13.3%) and dose adjustment by renal and/or hepatic function (11.5%). Acceptance rate of pharmacist therapy advice in evaluable cases was 81.0%. Medical versus surgical admitting department, specific types of intervention (addition of a new drug, drug discontinuation and correction of a prescription error) and oral communication of the recommendation were associated with a higher acceptance rate. The results of this study allow areas to be identified on which to implement optimization strategies. These include training courses for physicians on the computerized physician order entry, on drugs that need dose adjustment with renal impairment, and on relevant drug interactions.

Pharmacotherapy of amphetamine-type stimulant dependence: an update.
Brensilver, Matthew; Heinzerling, Keith G; Shoptaw, Steven
2013-09-01
Methamphetamine- or amphetamine-type stimulants are the second most frequently used illicit drug worldwide, second only to cannabis. Behavioural treatments are efficacious, but their impact is limited underscoring the need for other treatment options, notably, pharmacotherapy. A review of randomised controlled trials of pharmacotherapies for methamphetamine- or amphetamine-type stimulants was performed using PubMed and Google Scholar databases. Evidence for efficacy of medications is reported. Clinical trials have yielded no broadly effective pharmacotherapy. Promising signals have been observed for methylphenidate, naltrexone, bupropion and mirtazapine in subgroups of patients in reducing stimulant use (e.g. patients with less severe dependence at baseline and men who have sex with men), though none has produced an unambiguous, replicable signal of efficacy. Problems in Phase II trials, including high dropout rates, missing data and a lack of agreement on outcomes, complicate efforts to find a broadly effective pharmacotherapy for amphetamine-type stimulant disorders. Efforts to address these problems include calls for better validation of pharmacological target exposure, receptor binding and functional modulation. As well, there is a need for agreement in using findings from preclinical and early phases of the medication development process for selecting better pharmacotherapy candidates. After over 20 years of efforts worldwide to develop a broadly effective medication for dependence on methamphetamine- or amphetamine-type stimulants, no candidate has emerged. This highlights the need for new compounds, consistent and stringent research methods, better integration between preclinical and clinical stages of medication development, and improved collaboration between government, industry and researchers. © 2013 Australasian Professional Society on Alcohol and other Drugs.

Objective: Previous research indicates relationships between alcohol/substance misuse and criminal behavior, but past studies have restricted investigations to atypical samples and/or utilized limited assessments of illegal behavior. In the present study, we explored relationships between alcohol/drug problems and charges for 27 criminal behaviors in a primary care sample. Method: Participants were a cross-sectional sample of 376 consecutive men and women, aged 18 years or older, being seen for nonemergent medical care at an outpatient internal medicine clinic staffed predominantly by residents and located in a midsized, midwestern city in October 2010. Using a self-report survey methodology, we examined relationships between alcohol and drug problems (“Have you ever had a problem with alcohol?” and “Have you ever had a problem with drugs?”) and 27 illegal behaviors as delineated by the categories used by the US Federal Bureau of Investigation. Results: Men with alcohol or drug problems statistically exhibited the greatest number of charges for different forms of illegal behavior (P < .001). These charges were directly related to alcohol/drug misuse (eg, driving under the influence of alcohol or drugs) and otherwise (eg, aggravated assault, simple assault, gambling, larceny-theft). Conclusions: In primary care settings, men with alcohol/drug problems may also have a history of illegal behaviors—a finding that is relevant in terms of social and legal implications. PMID:22454803

The development and implementation of programs in the U.S. to minimize risks and assess unintended consequences of new medications has been increasingly required by the Food and Drug Administration (FDA) since the mid 1990s. This paper provides four case histories of risk management and post-marketing surveillance programs utilized recently to address problems associated with possible abuse, dependence and diversion. The pharmaceutical sponsors of each of these drugs were invited to present their programs and followed a similar template for their summaries that are included in this article. The drugs and presenting companies were OxyContin, an analgesic marketed by Purdue Pharma L.P., Daytrana and Vyvanse, ADHD medications marketed by Shire Pharmaceuticals, Xyrem for narcolepsy marketed by Jazz Pharmaceuticals, and Subutex and Suboxone for opioid dependence marketed by Reckitt Benckiser Pharmaceuticals Inc. These case histories and subsequent discussions provide invaluable real-world examples and illustrate both the promise of risk management programs in providing a path to market and/or for keeping on the market drugs with serious potential risks. They also illustrate the limitations of such programs in actually controlling unintended consequences, as well as the challenge of finding the right balance of reducing risks without posing undue barriers to patient access. These experiences are highly relevant as the FDA increasingly requires pharmaceutical sponsors to develop and implement the more formalized and enforceable versions of the risk management term Risk Evaluation and Mitigation Strategies (REMS).

Educating nursing faculty about the use of an evidence-based practice to screen and intervene earlier along the continuum of alcohol and other drug use, misuse, and dependence is essential in today's health care arena. Misuse of alcohol and other drugs is a significant problem for both individual health and societal economic welfare. The purpose of this article is to describe nursing faculty buy-in for the implementation of an evidence-based addiction training program at a university-based school of nursing. Derived from an academic-community partnership, the training program results suggest implications for continuing education and curriculum innovation in schools of nursing and clinical practice. The training content presented can be used in continuing education for nursing faculty across all types of nursing school programs and professional nursing staff employed in multiple settings. The training program was funded by the Health Resources and Services Administration.

The study examined the prevalence and correlates of heavy smoking and nicotine dependence in adolescents with bipolar and cannabis use disorders. Participants were 80 adolescents between 13 and 22 years of age with co-occurring bipolar I disorder and cannabis abuse or dependence who reported ever trying a cigarette. Diagnostic and symptom severity measures were completed as part of the baseline assessments for a clinical trial. Almost half (49%) of these participants who ever tried a cigarette were current heavy smokers (≥10 cigarettes/day), and 70% met DSM-IV-TR lifetime criteria for nicotine dependence. Heavy smoking was associated with older age, heavier marijuana use and greater compulsive craving, lifetime diagnoses of attention-deficit/hyperactivity disorder, conduct disorder, illicit drug use disorders, and poorer overall functioning. Nicotine dependence was related to White race, higher current mania severity, and poorer overall functioning. These findings suggest that heavy smoking and nicotine dependence were highly prevalent among these adolescents. Although both were associated with greater physical and psychosocial problems, only heavy smoking was linked to a clear pattern of more severe substance-related and psychiatric problems. Further research to elucidate mechanisms and develop interventions to address early, entrenched patterns of co-use of tobacco and marijuana is warranted. Copyright © 2013 Elsevier Ireland Ltd.

This paper reports on a qualitative study of the attitudes and risk management strategies of a sample of problem drug users in relation to driving while under the influence of drugs. Interviews were conducted with 26 individuals (21 men and 5 women) all of whom had been addicted to heroin and had admitted to driving while under the influence of illegal drugs. The drug users reported four main strategies for managing the risks associated with drug driving: attempting to limit their drug intake to their tolerance level; delaying driving after taking a drug until they felt safe; stopping driving if they felt unsafe while behind the wheel; and avoiding driving altogether under the influence of certain drugs. However, the interviewees' accounts of their drug driving behaviour suggest that these strategies are not only far from reliable, they may also act to encourage drug driving by creating a false sense of security. The reassurance they provide may also undermine any educational messages targeting drug driving. There was little in the problem users' accounts to suggest that media campaigns or a more effective method of detection would have much influence upon their behaviour. The paper concludes that the most realistic approach to the problem may be to incorporate drug driving interventions within drug treatment programmes.

This study examines reasons why people do not seek help for alcohol or drug problems by gender and race/ethnicity using data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a nationally representative survey. Multivariate models were fit for 3 barriers to seeking help (structural, attitudinal, and readiness for change) for either alcohol or drug problems, controlling for socio-demographic characteristics and problem severity. Predicted probabilities were generated to evaluate gender differences by racial/ethnic subgroups. Over three quarters of the samples endorsed attitudinal barriers related to either alcohol or drug use. Generally, women were less likely to endorse attitudinal barriers for alcohol problems. African Americans and Latina/os were less likely than Whites to endorse attitudinal barriers for alcohol problems, Latina/os were less likely than Whites to endorse readiness for change barriers for alcohol and drug problems, however, African Americans were more likely to endorse structural barriers for alcohol problems. Comparisons within racial/ethnic subgroups by gender revealed more complex findings, although across all racial/ethnic groups women endorsed attitudinal barriers for alcohol problems more than men. Study findings suggest the need to tailor interventions to increase access to help for alcohol and drug problems that take into consideration both attitudinal and structural barriers and how these vary across groups.

Tuberculosis is rapidly becoming a major health problem. The rise in tuberculosis incidence stimulates efforts to develop more effective delivery systems for the existing antituberculous drugs while decreasing the side effects. The nanotechnology may provide novel drug delivery tools allowing controlled drug release. Rifampicin is one of the main antituberculous drugs, characterized by high toxicity, and Poly (L-lactic acid) (PLLA) is a biodegradable polymer used for the preparation of encapsulated drugs. The aim of our work was to evaluate the toxicity of rifampicin-PLLA nanoparticles against Mycobacterium bovis BCG using human macrophage THP-1 cell line. Our data demonstrate that rifampicin-PLLA is effective against M. bovis BCG in the infected macrophages. The drug is inducing the dysfunction of mitochondria and apoptosis in the macrophages and is acting as a potential substrate of Pgp thereby modulating cell chemosensitivity. The severity of the toxic effects of the rifampicin-PLLA nanoparticles is increasing in a dose-dependent manner. We suggest that free rifampicin induces death of M. bovis BCG after PLLA degradation and diffusion from phago-lysosomes to cytoplasm causing mitochondria dysfunction and affecting the Pgp activity.

Background/problem. Monitoring of tumor response to cancer chemotherapy and dose optimization for specific patients are the key factors for successful application of anti-tumor drugs. Using patient's tumor cells for preliminary in vitro drug screening may allow optimal selection of drug type and dose. Method. Single cell state was studied with photothermal microscope. Carcinoma cells were irradiated at 427 nm with 8 ns laser pulse with energy 30 - 40 μJ. Cell photothermal (PT) response amplitude and shape from each cell were analyzed and amount of cells that produced specific PT response was used as PT parameter. Parallel experiment included cell viability control. Results were obtained for two cytotoxic chemotherapy agents -- Platinol-aq and Adrucil. Incubation of cell suspensions for 90 min at 20 and 37°C caused changes in cell PT parameters. Reaction of carcinoma cells to the drug was very similar to reaction of hepatocytes to respiratory chain inhibition and reaction of RBC to osmotic pressure decrease. PT effect was found to be dose-dependent. PT method allows detecting drug-induced changes before cell death or morphological changes and therefore can be fast and sensitive modality for control of chemotherapy.
Management of functional dyspepsia: Unsolved problems and new perspectives.
Madisch, Ahmed; Miehlke, Stephan; Labenz, Joachim

The common characteristic criteria of all functional gastrointestinal (GI) disorders are the persistence and recurrence of variable gastrointestinal symptoms that cannot be explained by any structural or biochemical abnormalities. Functional dyspepsia (FD) represents one of the important GI disorders in Western countries because of its remarkably high prevalence in general population and its impact on quality of life. Due to its dependence on both subjective determinants and diverse country-specific circumstances, the definition and management strategies of FD are still variably stated. Clinical trials with several drug classes (e.g., proton pump inhibitors, H2-blockers, prokinetic drugs) have been performed frequently without validated disease-specific test instruments for the outcome measurements. Therefore, the interpretation of such trials remains difficult and controversial with respect to comparability and evaluation of drug efficacy, and definite conclusions can be drawn neither for diagnostic management nor for efficacious drug therapy so far. In view of these unsolved problems, guidelines both on the clinical management of FD and on the performance of clinical trials are needed. In recent years, increasing research work has been done in this area. Clinical trials conducted in adequately diagnosed patients that provided validated outcome measurements may result in better insights leading to more effective treatment strategies. Encouraging perspectives have been recently performed by methodologically well-designed treatment studies with herbal drug preparations. Herbal drugs, given their proven efficacy in clinical trials, offer a safe therapeutic alternative in the treatment of FD which is often favored by both patients and physicians. A fixed combination of peppermint oil and caraway oil in patients suffering from FD could be proven effective by well-designed clinical trials.

Ayahuasca is a psychoactive beverage used for magico-religious purposes in the Amazon. Recently, Brazilian syncretic churches have helped spread the ritual use of ayahuasca abroad. This trend has raised concerns that regular use of this N,N-dimethyltryptamine-containing tea may lead to the medical and psychosocial problems typically associated with drugs of abuse. Here we assess potential drug abuse-related problems in regular ayahuasca users. Addiction severity was assessed using the Addiction Severity Index (ASI), and history of alcohol and illicit drug use was recorded. In Study 1, jungle-based ayahuasca users (n=56) were compared vs. rural controls (n=56). In Study 2, urban-based ayahuasca users (n=71) were compared vs. urban controls (n=59). Follow-up studies were conducted 1 year later. In both studies, ayahuasca users showed significantly lower scores than controls on the ASI Alcohol Use, and Psychiatric Status subscales. The jungle-based ayahuasca users showed a significantly higher frequency of previous illicit drug use but this had ceased at the time of examination, except for cannabis. At follow-up, abstinence from illicit drug use was maintained in both groups except for cannabis in Study 1. However, differences on ASI scores were still significant in the jungle-based group but not in the urban group. Despite continuing ayahuasca use, a time-dependent worsening was only observed in one subscale (Family/Social relationships) in Study 2. Overall, the ritual use of ayahuasca, as assessed with the ASI in currently active users, does not appear to be associated with the deleterious psychosocial effects typically caused by other drugs of abuse.

The purpose of this study was to investigate the association between depression and illicit drug dependence among a Latin-American population. illicit drug dependent patients (n = 137) and controls (n = 274) were interviewed using the Diagnostic Interview for Genetic Studies, in order to detect lifetime and current depressive disorder and illicit (cocaine, cannabis or inhalants) substance dependence. A regression analysis was used to estimate the odds ratio for drug dependence according to the diagnosis of depression. The lifetime diagnosis of depression (p = 0.001; OR = 4.9; 95% CI, 1.9-12.7) predicts illegal drugs dependence. Sociodemographic variables such as male gender (p < 0.001; OR = 36.8; 95% CI, 11.8-114) and occupational situation (p = 0.002; OR = 5.0; 95% CI, 1.8-13) as well as alcohol dependence (p = 0.01; OR = 3.4; 95% CI, 1.3-8.7) significantly influenced depression and drug dependence. Additional influent factors detected were having parents (p = 0.006; OR = 18.9; 95% CI, 2.3-158) or friends (p < 0.001; OR = 64.4; 95% CI, 6.5-636) who are illicit drugs dependents. although a causal relationship between dependence on illicit drugs and depression cannot be determined, comparison of the sequence of events point to the occurrence of depression later in life than dependence. It remains to be determined whether depression is a comorbidity of dependence, sharing etiological factors, or a consequence of drug abuse and/or abstinence.

Insomnia and excessive daytime sleepiness (EDS) are frequently observed conditions in the general public. A national survey in the USA in 1979 indicated that 35% of American adults experience insomnia in the course of a year. The prevalence of EDS varies depending on the survey (0.3 to 13.3%), but a recent study stated that 2.4% of individuals reported that they continually fell asleep at work. These problems are often long term and negatively affect the individuals' quality of life. People with these sleep problems often have difficulties maintaining high levels of productivity at work or pursuing their daily activities; individuals with insomnia lack the feeling of being rested or refreshed in the morning and EDS is unavoidable in most cases. Behavioural therapy has been shown to be effective for many people affected with insomnia and EDS. However, pharmacological treatments using hypnosedatives and central nervous system (CNS) stimulants are usually necessary, and effective, for those with more severe cases. These compounds have thus been widely prescribed in clinical practice (e.g., 2.6% of all adults surveyed used medically prescribed hypnosedatives and 4.5% used over-the-counter drugs to promote sleep). The onset and duration of action of these hypnosedatives and CNS stimulant drugs are important factors to be considered when prescribing these compounds. These factors primarily depend on physicochemical properties (lipid solubility and protein binding), as well as the pharmacokinetic profile (absorption, distribution, elimination and clearance) of the compounds. Significant differences in profile exist amongst hypnosedatives and CNS stimulants, and these differences may account for the observed variations in clinical action and adverse effects during and after treatment. In this review, we will introduce recently obtained knowledge of the pharmacokinetics of hypnosedatives and CNS stimulants and their applications for patients affected with insomnia and EDS.

Little is known about the correlates of comorbid drug and alcohol dependence in people with schizophrenia outside the USA. We tested hypotheses that dependence on alcohol/drugs would be associated with more severe symptoms, and poorer psychosocial functioning and quality of life. The EuroSC Cohort study (N=1204), based in France, Germany and the UK, used semi-structured clinical interviews for diagnoses, and standardized tools to assess correlates. We used mixed models to compare outcomes between past-year comorbid dependence on alcohol/drugs, controlling for covariates and modelling both subject and country-level effects. Participants dependent on alcohol or drugs had fewer negative symptoms on PANSS than their non-dependent counterparts. However, those dependent on alcohol scored higher on PANSS general psychopathology than those who were not, or dependent only on drugs. People with schizophrenia dependent on drugs had poorer quality of life, more extrapyramidal side effects, and scored worse on Global Assessment of Functioning (GAF) than those without dependence. People with alcohol dependence reported more reasons for non-compliance with medication, and poorer functioning on GAF, though not on Global Assessment of Relational Functioning. In people with schizophrenia, comorbid dependence on alcohol or drugs is associated with impaired clinical and psychosocial adjustment, and poorer quality of life.

Social capital has become an influential concept in debating and understanding the modern world. Within the drug and alcohol sector, the concept of 'recovery capital' has gained traction with researchers suggesting that people who have access to such capital are better placed to overcome their substance use-related problems than those who do not (Cloud and Granfield, 2008), leading to requests for interventions that focus on building social capital networks (Neale & Stevenson, 2015). While accepting that the concept of social capital has enormous potential for addressing the problems associated with drug use, this paper also considers its 'dark side'. Data were drawn from semi-structured interviews with 180 participants including 135 people who use drugs and 45 people who formerly used drugs. High levels of trust, acquired through the establishment of dense social networks, are required to initiate recovery. However, these 'strong bonds' may also lead to the emergence of what is perceived by others as an exclusive social network that limits membership to those who qualify and abide by the 'rules' of the recovery community, particularly around continuous abstinence. Depending on the nature of the networks and the types of links participants have into them being socially connected can both inhibit and encourage recovery. Therefore, the successful application of social capital within the drugs and alcohol field requires a consideration of not only the presence or absence of social connections but their nature, the value they produce, and the social contexts within which they are developed.

It is not clear from prior studies whether trauma exposure predicts substance use problems independent of psychiatric comorbidities. Most prior studies were cross-sectional in nature, and none focused on prescription drug problems. To address this gap in the literature, the current article is a secondary analysis of veterans from the Mind Your Heart prospective cohort study. The primary research question is whether trauma exposure predicts prescription drug problems even after controlling for major psychiatric symptoms, such as post-traumatic stress disorder and depression. Multinomial logistic regression was used to assess whether the 10-item lifetime Brief Trauma Questionnaire (e.g., serious car accidents, war traumas, life-threatening illness, natural disasters, physical, or sexual abuse) predicts prescription drug problems as determined by a self-report categorical question (three answer choices) over a 4-year follow-up time period (n = 661 [100%] at year 1; 83.4% at year 2; 85.9% at year 3; and 78.2% at year 4). Trauma exposure was positively associated with prescription drug problems in unadjusted and age-, sex-, and race-adjusted analyses at follow-up. After accounting for post-traumatic stress disorder (PTSD Checklist-17 Civilian Version) and depression (Patient Health Questionnaire-9) symptoms, trauma exposure was no longer associated with prescription drug problems at all time points (relative risk ratios range 0.91-1.47). These results were robust to different missing data strategies. Trauma exposure was not associated with prescription drug problems over a 4-year follow-up in a prospective cohort study of veterans. Future directions include detailed measures of prescription drug problems and recruitment from community sites.
Problem based review: The patient taking methadone.
Arora, Alok; Williams, Karen
2013-01-01
Methadone maintenance treatment (MMT) is an effective therapy for opioid-dependence; its use is based on a harm reduction philosophy and represents one of a range of treatment approaches for opioid-dependent individuals. The medical literature supports MMT as a well established and cost-effective treatment for opioid-dependence that allows a return-to-normal physiological, psychological and societal functioning. The effectiveness of MMT is enhanced by psycho-social interventions such as contingency management and addressing other co-existing health and social needs. MMT saves lives and reduces violent and non-violent crime, drug use and the transmission of HIV, hepatitis C and other communicable diseases. For some people, MMT may continue for life, while others may eventually be able to discontinue and remain abstinent. Methadone interacts with numerous drugs and prolongs the corrected QT interval (QTc) with risk of sudden cardiac death. It has a prolonged half-life and premature discharge of patients after methadone overdose may be fatal. Each patient must be assessed, treated and monitored on an individual basis. Successful outcomes through MMT require knowledge, experience, vigilance, and diligence on the part of the physician, the patient and all of those involved in treatment.
Study of the deposition process of vinpocetine on the surface of porous silicon

Lenshin, A. S.; Polkovnikova, Yu. A.; Seredin, P. V.
Currently the most prospective way in pharmacotherapy is the obtaining of nanoparticles involving pharmaceutical substances. Application of porous inorganic materials on the basis of silicon is among the main features in solving of this problem. The present work is concerned with the problem of the deposition of pharmaceutical drug with nootropic activity - vinpocetine - into porous silicon. Silicon nanoparticles were obtained by electrochemical anodic etching of Si plates. The process of vinpocetine deposition was studied in dependence of the deposition time. As a result of the investigations it was found that infrared transmission spectra of porous silicon with the deposited vinpocetine revealed the absorption bands characteristic of vinpocetine substance.

What do I as a critical care nurse do? Nurses, by virtue of being trained in health promotion, and also because they interact with patients, families, and communities, have firsthand opportunities to play an active role in practicing primary prevention. To avoid the first occurrence of substance abuse, assess community need, assess facility needs, and identify potential risk. Identify the magnitude of the problem. Intervene early with the youth and at-risk populations. Refer patients and their families to mental health specialists. Provide education to patients, families, communities. To reduce occurrences of substance abuse, practicing secondary prevention requires prompt action in the earliest moments of recognizing a problem and directing patients to early intervention and rehabilitation. Screening your patients, providing brief education, and prompt referral constitutes early intervention. To retard the progress of the disease, practice tertiary prevention by providing education, counseling, and support to the afflicted in achieving and maintaining sobriety through medication compliance and rehabilitative group and counseling work. The goal of intervention in the lives of substance abusers is to stop drug use, avoid relapse, and sustain recovery. After years of research, NIDA has identified 13 fundamental principles to effective drug abuse treatment. 1. Addiction is a complex but treatable disease that affects brain function and behavior. 2. No single treatment is appropriate for everyone. 3. Treatment needs to be readily available. 4. Effective treatment attends to multiple needs of the individual, not just his or her drug abuse. 5. Remaining in treatment for an adequate period of time is critical. 6. Counseling--individual and/or group--and other behavioral therapies are the most commonly used forms of drug abuse treatment. 7. Medications are an important element of treatment for many patients, especially when combined with counseling and other behavioral therapies. 8. An individual's treatment and services plan must be assessed continually and modified as necessary to ensure it meets his or her changing needs. 9. Many drug-addicted individuals also have other mental disorders that need treatment. 10. Medically assisted detoxification in the first stage of addiction treatment and by itself does little to change long-term drug abuse. 11. Treatment does not need to be voluntary to be effective. 12. Drug use during treatment must be monitored continuously, because lapses during treatment do occur. 13. Treatment programs should assess patients for the presence of HIV/AIDS, hepatitis B and C, tuberculosis, and other infectious diseases, as well as provide targeted risk-reduction counseling to help patients modify or change behaviors that place them at risk of contracting or spreading infectious diseases. To truly impact this disease, there needs to be improvement in the identification of risk factors and early identification and early intervention with children and adolescents. The future of neuroscience is in objective brain scans and genetic testing. Out of these approaches can come more objective measures of addiction and dependence using brain scans and genetic testing. These measures would potentially allow for the development of vaccines for specific drugs of abuse and dependence, as well as increasingly selective and effective pharmacologic approaches for treatment and a new consensus on standard of care for substance dependence.
Development and validation of a Client Problem Profile and Index for drug treatment.
Joe, George W; Simpson, D Dwayne; Greener, Jack M; Rowan-Szal, Grace A
2004-08-01
The development of the Client Problem Profile and Index are described, and initial concurrent and predictive validity data are presented for a sample of 547 patients in outpatient methadone treatment. Derived from the TCU Brief Intake for drug treatment admissions, the profile covers 14 problem areas related to drug use (particularly cocaine, heroin/opiate, marijuana, other illegal drugs, and multiple drug use), HIV risks, psychosocial-functioning, health, employment, and criminality. Analyses of predictive validity show the profile and its index (number of problem areas) were significantly related to therapeutic engagement, during-treatment performance, and posttreatment follow-up outcomes. Low moderate to high moderate effect sizes were observed in analyses of the index's discrimination.

In traumatized populations, drug use disorders and post-traumatic stress disorder (PTSD) persist for many years. Relational factors that mediate this persistence have rarely been systematically examined. Our aim is to examine the relative effects of psychopathology in familial and non-familial networks on the persistence of both disorders over adulthood. We utilized longitudinal data from an epidemiologically ascertained sample of male Vietnam veterans (n=642). Measures included DSM-IV drug use disorders, other psychiatric disorders, network problem history and time-varying marital and employment characteristics. Longitudinal measures of veterans' psychopathology and social functioning were retrospectively obtained for each year over a 25 year period. We used generalized estimating equations (GEE) to estimate the relative effects of network problems on veteran's drug use disorders and PTSD after adjusting for covariates. Veterans' mean age was 47 years in 1996. Prevalence of illicit drug disorders declined from 29.8% in 1972 to 8.3% in 1996, but PTSD remained at 11.7% from 13.2% in 1972. While 17.0% of veterans reported a familial drug use problem, 24.9% reported a non-familial drug use problem. In full GEE models, a non-familial drug problem was a significant predictor of illicit drug use disorders over 25 years (OR=2.21, CI=1.59-3.09), while both familial depression (OR=1.69, CI=1.07-2.68) and non-familial drinking problem (OR=1.66, CI=1.08-2.54) were significant predictors of PTSD over 25 years. Familial and non-familial problems in networks differentially affect the persistence of drug use disorders and PTSD in traumatized male adults. Copyright © 2013 Elsevier Ireland Ltd.

"Krokodil":revival of an old drug with new problems.
Gahr, Maximilian; Freudenmann, Roland W; Hiemke, Christoph; Gunst, Ingo M; Connemann, Bernhard J; Schönfeldt-Lecuona, Carlos
2012-06-01
In order to summarize current knowledge about the drug "Krokodil" a systematic review including a literature search of the databases PubMed, Embase, Scopus, and Google was conducted in December 2011. According to information acquired, "Krokodil" is a mixture of several substances and was first reported to have been used in Russia in 2003. The core agent of "Krokodil" is desomorphine, an opioid-analogue that can be easily and cheaply manufactured by oneself. Self-production results in a contaminated suspension that is injected intravenously. Due to its pharmacologic features, desomorphine shows a high potential to cause dependence. Against the background of first possible cases of "Krokodil" use in Western Europe, it appears advisable to provide information regarding the fatal consequences of "Krokodil."
Child abuse, drug addiction and mental health problems of incarcerated women in Israel.
Chen, Gila; Gueta, Keren
2015-01-01
The mental health problems and pathways to drug addiction and crime among female inmates have long been of interest to researchers and practitioners. The purpose of the current study was to examine the possible association between multiple types of childhood abuse, mental health problems, and drug addiction and the incarceration of 50 Israeli women in prison. The findings indicated that female inmates come from risky families with a high prevalence of family mental health problems, parental drug addiction and crime, and sibling drug addiction and crime. Furthermore, they revealed that incarcerated women from risky families were victims of multiple types of childhood abuse and neglect by their parents, as well as their siblings. Overall, the results suggest that the adverse consequences of a family's mental health problems are much more dramatic than we assumed to date, and that women are more likely than men to be the victims of multiple types of childhood abuse and neglect, as well as suffering more severe psychiatric problems, depression, and drug addiction. The implications of these findings are discussed. Copyright © 2015 Elsevier Ltd. All rights reserved.
Profile of inhalant users seeking treatment at a de-addiction centre in north India.
Gupta, Sunil; Nebhinani, Naresh; Basu, Debasish; Mattoo, Surendra Kumar
2014-05-01
Inhalants are substances whose chemical vapors are inhaled to produce euphoric, disinhibiting, and exciting effects. Data on inhalant abuse in India are relatively scarce. We report the demographic and clinical profile of inhalant users among the treatment seekers at a Drug De-addiction and Treatment Centre in north India. The records of treatment seekers at the Drug De-addiction and Treatment Centre, over 10 years (2002-2011) were scanned to identify 92 cases reporting inhalant use. Of these 92 cases, the complete record files were available for 87 (94.6%) cases. These case files were reviewed and the relevant data were collected and analyzed. Over the study period of 10 years, the number of cases with inhalant abuse per year rose steadily to peak at 20 cases (4.08% of new cases) in 2006 and then stabilized at 1-3 per cent of new cases annually. Of the 87 cases studied, all were males with a mean age of 18.9±4.12 yr, mean education of 9.8±3.42 yr and mean family income of Rs. 7676±7343.15 (median: Rs. 5000). Majority of subjects were unmarried (89.7%), urban resident (79.3%), and from a nuclear family (78.2%). About half of the subjects were students (50.6%). The most common inhalant used was typewriter correction fluid (73.6%) followed by typewriter diluent fluid (19.5%) and glue (6.9%). The most common reason for initiation was curiosity. The mean age of onset of inhalant use was 16.3±4.22 yr. Most subjects fulfilled the criteria for inhalant dependence (85.1%). Psychiatric co-morbidity and the family history of substance dependence were present in 26.4 and 32.9 per cent subjects, respectively. Majority of the subjects reported drug related problems, occupation and finance being the worst affected. Interpretations & conclusions: Our results showed that the inhalant users were mostly urban youth belonging to middle socio-economic class families. The principal sources of inhalant abuse were the commonly available substances like typewriter correction fluids and majority of the subjects initiated it out of curiosity. Nearly three-fourth of the subjects used some other substance of abuse in addition, tobacco being the most common. In view of associated drug related problems, there is a need for strategies to prevent this emerging health care problem.
Cocaine impairs serial-feature negative learning and blood-brain barrier integrity.

Previous research has shown that diets high in fat and sugar [a.k.a., Western diets (WD)] can impair performance of rats on hippocampal-dependent learning and memory problems, an effect that is accompanied by selective increases in hippocampal blood brain barrier (BBB) permeability. Based on these types of findings, it has been proposed that overeating of a WD (and its resulting obesity) may be, in part, a consequence of impairments in these anatomical substrates and cognitive processes. Given that drug use (and addiction) represents another behavioral excess, the present experiments assessed if similar outcomes might occur with drug exposure by evaluating the effects of cocaine administration on hippocampal-dependent memory and on the integrity of the BBB. Experiment 1 of the present series of studies found that systemic cocaine administration in rats also appears to have disruptive effects on the same hippocampal-dependent learning and memory mechanism that has been proposed to underlie the inhibition of food intake. Experiment 2 demonstrated that the same regimen of cocaine exposure that produced disruptions in learning and memory in Experiment 1 also produced increased BBB permeability in the hippocampus, but not in the striatum. Although the predominant focus of previous research investigating the etiologies of substance use and abuse has been on the brain circuits that underlie the motivational properties of drugs, the current investigation implicates the possible involvement of hippocampal memory systems in such behaviors. It is important to note that these positions are not mutually exclusive and that neuroadaptations in these two circuits might occur in parallel that generate dysregulated drug use in a manner similar to that of excessive eating.

A classification of substance-dependent men on temperament and severity variables.
Henderson, Melinda J; Galen, Luke W
2003-06-01
This study examined the validity of classifying substance abusers based on temperament and dependence severity, and expanded the scope of typology differences to proximal determinants of use (e.g., expectancies, motives). Patients were interviewed about substance use, depression, and family history of alcohol and drug abuse. Self-report instruments measuring temperament, expectancies, and motives were completed. Participants were 147 male veterans admitted to inpatient substance abuse treatment at a U.S. Department of Veterans Affairs medical center. Cluster analysis identified four types of users with two high substance problem severity and two low substance problem severity groups. Two, high problem severity, early onset groups differed only on the cluster variable of negative affectivity (NA), but showed differences on antisocial personality characteristics, hypochondriasis, and coping motives for alcohol. The two low problem severity groups were distinguished by age of onset and positive affectivity (PA). The late onset, low PA group had a higher incidence of depression, a greater tendency to use substances in solitary contexts, and lower enhancement motives for alcohol compared to the early onset, high PA cluster. The four-cluster solution yielded more distinctions on external criteria than the two-cluster solution. Such temperament variation within both high and low severity substance abusers may be important for treatment planning.

The aim of this study was to explore Greek problem drug users’ perceptions of the reasons that led them to quit using drugs and engage in treatment of their own volition. Qualitative semi-structured in-depth interviews. Two state drug agencies in Thessaloniki, Greece. A total of 40 adult problem drug-using men and women participated in the study. Participants were asked to reflect on their decisions to wean themselves from drugs and enter treatment. Findings Participants reported that their decisions centred on the re-conceptualization of the drug-using community and their membership in it, the desire to restore aspects of identities thatwere deemed to be spoiled, and finally memories of their drug-free selves. The importance of the distinctively Greek notion of filotimo in this discussion is highlighted. Primarily in relation to filotimo (a concept that represents a complex array of virtues that regulates behaviour towards one’s family), the desire to restore one’s spoiled identity plays a pivotal role in Greek problem drug users’ decisions to cease drug use and engage in treatment.

The nonmedical use of prescription drugs (NMUPD) is not only a serious public health problem, but also a complex one. The articles presented in this special issue underscore that complexity by describing multiple classes of prescription drugs (e.g., opioid analgesics, benzodiazepines, stimulants, anxiolytics, and sedatives) and examining multiple aspects of their patterns of use. Collectively, the articles examine epidemiologic use patterns in the United States, risk factors, clinical characteristics of individuals in treatment for dependence, and consequences. The key to addressing NMUPD is to construct a solid understanding of the issues through scientific research, and to translate the scientific evidence into action. The articles in this issue build upon a large body of literature that has accumulated during the last two decades. Dramatic increases in overdoses from prescription opioids and the transition to heroin use among nonmedical users of prescription opioids has captured the attention of community leaders across the nation. Yet, less well known is the co-occurrence of multiple substances among those using prescription drug nonmedically. This represents a common theme across these articles which document that nonmedical users were observed to have a history of using alcohol, marijuana, tobacco, and other psychoactive substances. In addition, the articles dispel certain ideas that appear to have gained traction in the popular discourse that have little scientific evidence behind them. First, the notion that prescription drug problems arise in cases of drug naïve individuals who are first exposed through a physician’s prescription for pain medication is widespread, but is not rooted in scientific evidence. Second, despite the popular notion that nonmedical use of stimulants confers an “academic edge”, nonmedical users have lower grade point averages (GPAs) than non-users. NMUPD was also shown to be associated with sexual aggression victimization and perpetration and regretted sex. In addition, several of the articles in this issue point to innovative targets for prevention of NMUPD. It is only through high-quality research can we gain a clearer understanding of the problem and how to address it. PMID:27639956
Is anybody listening? A phenomenological study of pain in hospitalized persons with AIDS.
Newshan, G
1998-01-01
Pain is a common problem among hospitalized persons with AIDS (PWAs), yet it has not been well studied. The purpose of this study was to understand, using the phenomenological method, the experience of pain in hospitalized PWAs. Multiple sources of data, including interviews with 11 hospitalized PWAs, literature, poetry, and film, were used to investigate the phenomenon. Five broad themes emerged: knowing pain, battling pain, having AIDS, pain's influence, and being a drug user. Multiple barriers to effective pain management were identified. Although there were commonalities in the experience of pain in chemically dependent and nonchemically dependent PWAs, unique challenges for the chemically dependent PWAs were identified. The findings indicate the importance of listening to and believing reports of pain. In addition, the findings underscore the delicate balance that exists between pain relief and relapse in PWAs with a history of chemical dependency.
Patterns of current and lifetime substance use in schizophrenia.
Fowler, I L; Carr, V J; Carter, N T; Lewin, T J
1998-01-01
A structured interview and standardized rating scales were used to assess a sample of 194 outpatients with schizophrenia in a regional Australian mental health service for substance use, abuse, and dependence. Case manager assessments and urine drug screens were also used to determine substance use. Additional measurements included demographic information, history of criminal charges, symptom self-reports, personal hopefulness, and social support. The sample was predominantly male and showed relative instability in accommodations, and almost half had a history of criminal offenses, most frequently drug or alcohol related. The 6-month and lifetime prevalence of substance abuse or dependence was 26.8 and 59.8 percent, respectively, with alcohol, cannabis, and amphetamines being the most commonly abused substances. Current users of alcohol comprised 77.3 percent and current users of other nonprescribed substances (excluding tobacco and caffeine) comprised 29.9 percent of the sample. Rates of tobacco and caffeine consumption were high. There was a moderate degree of concordance between case manager determinations of a substance-use problem and research diagnoses. Subjects with current or lifetime diagnoses of substance abuse/dependence were predominantly young, single males with higher rates of criminal charges; however, there was no evidence of increased rates of suicide attempts, hospital admissions, or daily doses of antipsychotic drugs in these groups compared with subjects with no past or current diagnosis of substance abuse or dependence. Subjects with a current diagnosis of substance use were younger at first treatment and currently more symptomatic than those with no past or current substance use diagnosis. The picture emerging from this study replicates the high rate of substance abuse in persons with schizophrenia reported in North American studies but differs from the latter in finding a slightly different pattern of substances abused (i.e., absence of cocaine), reflecting relative differences in the availability of certain drugs.
An ambiguous monolith - the Swedish drug issue as a political battleground 1965-1981.
Edman, Johan
2013-09-01
The drug problem has been a highly ideologized topic in the political debate in Sweden ever since the mid-1960s. The aim of the article is to investigate dominant conceptions of drugs, drug use, society and the individual in the political discussions on drug use in Sweden during the years 1965-1981. The empirical basis for the textual analysis consists of 146 parliamentary bills and 135 parliamentary protocols. The unwanted drug appear as a sensitive litmus paper, an indication that something had gone wrong in society and as a suggestion of how the good society could be accomplished. The drug problem was connected to ideological core values such as class struggle, Christianity or criticism of urbanism and modernity. The analysis suggests that the drug problem was used as political ammunition, to pick holes in political opponents and to highlight one's own ideological stance. The hegemonic conversational order, the consensual spirit and the agreement that this was the most serious problem, did not hamper these political moves. Rather, the cross-party conception of the problem's severity and accelerating deterioration contributed to a common ground for political arguments and ideological visions. It also meant that the political discussions moved away from the more obvious drug policy issues. Copyright © 2013 Elsevier B.V. All rights reserved.

Although intimate partner violence (IPV) has demonstrated strong associations with anxiety and posttraumatic stress, these constructs have rarely been examined simultaneously in IPV research. Gaps in knowledge remain as to their differential associations to substance use problems among IPV-victimized women. A sample of 143 community women self-reported on their current IPV victimization, mental health and substance use problems. Hierarchical entry multiple regressions were used to test for the direct and indirect effects of psychological, physical, and sexual IPV to alcohol and drug problems through anxiety and posttraumatic stress. Higher anxiety symptom severity and higher physical IPV severity were associated with greater alcohol and drug problems. Higher posttraumatic stress symptom severity was associated with greater alcohol and drug problems. Mediation analyses indicated (i) significant indirect pathways of IPV types to alcohol problems through posttraumatic stress symptom severity controlling for anxiety symptom severity and (ii) significant indirect pathways of IPV types to drug problems through anxiety symptom severity controlling for posttraumatic stress symptom severity. In examining the indirect pathways of psychological, physical, and sexual IPV to substance use problems this study highlights that anxiety and posttraumatic stress symptom severity have unique effects on alcohol and drug problems among IPV-victimized women.

Although drug abuse has been a serious public health concern, there have been problems with implementation of treatment for drug users in Japan because of poor accessibility to treatment, concerns about stigma and confidentiality, and costs. Therapeutic interventions using the Internet and computer technologies could improve this situation and provide more feasible and acceptable approaches. The objective of the study was to show how we developed a pilot version of a new Web-based cognitive behavioral relapse prevention program with tailored feedback to assist people with drug problems and assessed its acceptance and usability. We developed the pilot program based on existing face-to-face relapse prevention approaches using an open source Web application to build an e-learning website, including relapse prevention sessions with videos, exercises, a diary function, and self-monitoring. When users submitted exercise answers and their diary, researchers provided them with personalized feedback comments using motivational interviewing skills. People diagnosed with drug dependence were recruited in this pilot study from a psychiatric outpatient ward and nonprofit rehabilitation facilities and usability was evaluated using Internet questionnaires. Overall, website usability was assessed by the Web Usability Scale. The adequacy of procedures in the program, ease of use, helpfulness of content, and adverse effects, for example, drug craving, mental distress, were assessed by original structured questionnaires and descriptive form questions. In total, 10 people participated in the study and completed the baseline assessment, 60% completed all relapse prevention sessions within the expected period. The time needed to complete one session was about 60 minutes and most of the participants took 2 days to complete the session. Overall website usability was good, with reasonable scores on subscales of the Web Usability Scale. The participants felt that the relapse prevention sessions were easy to use and helpful, but that the length of the videos was too long. The participant who until recently used drugs was satisfied with the self-monitoring, but others that had already maintained abstinence for more than a year felt this activity was unhelpful and were bored tracking and recording information on daily drug use. Feedback comments from researchers enhanced participants' motivation and further insight into the disease. Serious adverse effects caused by the intervention were not observed. Some possible improvements to the program were suggested. The Web-based relapse prevention program was easy to use and acceptable to drug users in this study. This program will be helpful for drug users who do not receive behavioral therapy. After the pilot program is revised, further large-scale research is needed to assess its efficacy among drug users who have recently used drugs.
Parental rearing patterns and drug abuse. Preliminary report.
Kokkevi, A; Stefanis, C
1988-01-01
Results from a controlled study on a sample of 91 imprisoned drug dependents on perceived parental rearing practices using the EMBU and on parental family characteristics are presented. While few differences were observed between drug dependents and imprisoned controls-father less warm and mother more permissive in drug dependent group--comparisons of drug dependents with a general population sample revealed more differences between the two populations: drug dependents perceive both parents compared to the general population group as less rejective, very permissive, their mother as warmer and more overprotective and their father more inconsistent and less favouring them than siblings. Supportive evidence on the dependents' family psychopathology is provided by studying family characteristics. While our findings seem to support the prevailing view in the literature on the role of the mother of the drug dependent characterised by strong emotional bonds and overprotection as well as of the rather emotionally distant father, the question is raised on the contribution of other factors, such as psychopathic personality, on the above findings.

Drug abuse is a significant social and public health problem in Iran. The present study aimed to provide prevalence estimates and information on correlates of illicit drug use disorder and opioid dependence, as well as service use for these disorders in Iran. This report is based on the Iranian household Mental Health Survey (IranMHS) conducted in 2011. A three-stage probability sampling was employed. Face-to-face interviews by trained psychologists were carried out with a nationally representative sample of 7841 individuals (3366 men and 4475 women) aged 15-64 years. The Composite International Diagnostic Interview and questionnaires for socio-demographic correlates and service use. The prevalence of 12-month use disorders for any illicit drug according to DSM-IV and DSM-5 criteria were 2.09% [95% confidence interval (CI) = 1.70-2.47%] and 2.44% (95% CI = 2.03-2.85%), respectively. Opioid use disorders, and opium in particular, were the most common use disorder. The odds of drug use disorders were greater in men than in women, in previously married participants than in currently or never married participants, and in participants with lower socio-economic status than in those with higher socio-economic status (all P-values <0.05). Approximately half of those with drug use disorders and 40% with opioid dependence had a 12-month unmet need for treatment. Self-help groups were the most common type of service used, followed by obtaining medication from pharmacies directly and outpatient treatment services. Opioid use disorders are the most common type of drug use disorders in Iran, setting Iran apart from many other countries. Patterns of service use suggest a large unmet need for drug use disorder treatment in Iran. © 2016 Society for the Study of Addiction.
Factors affecting medication-order processing time.
Beaman, M A; Kotzan, J A
1982-11-01
The factors affecting medication-order processing time at one hospital were studied. The order processing time was determined by directly observing the time to process randomly selected new drug orders on all three work shifts during two one-week periods. An order could list more than one drug for an individual patient. The observer recorded the nature, location, and cost of the drugs ordered, as well as the time to process the order. The time and type of interruptions also were noted. The time to process a drug order was classified as six dependent variables: (1) total time, (2) work time, (3) check time, (4) waiting time I--time from arrival on the dumbwaiter until work was initiated, (5) waiting time II--time between completion of the work and initiation of checking, and (6) waiting time III--time after the check was completed until the order left on the dumbwaiter. The significant predictors of each of the six dependent variables were determined using stepwise multiple regression. The total time to process a prescription order was 58.33 +/- 48.72 minutes; the urgency status of the order was the only significant determinant of total time. Urgency status also significantly predicted the three waiting-time variables. Interruptions and the number of drugs on the order were significant determinants of work time and check time. Each telephone interruption increased the work time by 1.72 minutes. While the results of this study cannot be generalized to other institutions, pharmacy managers can use the method of determining factors that affect medication-order processing time to identify problem areas in their institutions.
Drug retailer training: experiences from Nepal.

Sale of modern medicines by untrained peddlers, general merchants, and other drug sellers is common throughout the developing world. Drug sellers operating in the 'informal sector' are often the first source of health care outside the home. Reasons given by patients for using private drug sellers include expediency, convenience, efficacy of the medicines, dependability of supply, and reasonable cost. At the same time, self-medication through private drug sellers can be ineffective, wasteful, and at times distinctly harmful. Regulatory approaches to controlling drug selling in the informal sector, widely endorsed on paper through national drug control legislation, require a cadre of professional regulatory staff and enforcement mechanisms which are too often beyond the current economic and political reach of countries. In Nepal, where rugged terrain has limited infrastructure development, the doctor to population ratio is 1:23,000, utilization of government health services averages only 0.2 visits per person per year. Retail drug outlets outnumber health posts and health centers by a ratio of 4:1 and private drug sellers often offer the only access to modern medicine for much of the population. Community surveys have found that drug retailers are very often the first and only source of health care outside the home. Given the importance of retail drug outlets and the lack of trained pharmacists, the Department of Drug Administration in 1981 established a 45-hr course for drug retailers which emphasized practical training as well as formal teaching on pharmacology, ethics, storage of drugs, and legal issues. By the end of 1989, 4096 drug retailers had graduated from the course. Still run by the Ministry of Health Department of Drug Administration, the course has proven to be administratively feasible and has been quite popular with drug retailers. Initial reservations expressed by doctors and some pharmacists were soon overcome, and the course is now well accepted by professional groups. Because the course is offered in different locations, geographic coverage has also been very good despite Nepal's logistic constraints. The operating cost of the course averages about U.S. $18 per trainee. Informal evaluations have resulted in plans for refresher training more narrowly focused on safe dispensing and appropriate referral for a limited number of important public health problems. Since 50-90% of pharmaceutical expenditures typically pass through the informal private sector in developing countries, it is suggested that other countries consider focused drug retailer training as a response to the problems of manpower shortages and drug dispensing by unqualified staff.

Psychotropic drugs are a cornerstone in the treatment of psychopathology and/or behavioral problems in children with intellectual disability (ID), despite concerns about efficacy and safety. Studies on the prevalence of psychotropic drug use have mainly been focused on adults with ID or children without ID. Therefore the aim of this cross sectional study was to assess the prevalence and characteristics of psychotropic drug use in children with mild ID who were institutionalized in specialized inpatient treatment facilities in The Netherlands. Demographic data, psychiatric diagnoses, the nature of the behavioral problems, level of intellectual functioning, and medication data were extracted from medical records using a standardized data collection form. Adjusted relative risks (ARR) for the association between patient characteristics and psychotropic drug use were estimated with Cox regression analysis. Of the 472 included children, 29.4% (n=139) used any psychotropic drug, of which 15.3% (n=72) used antipsychotics (mainly risperidone), and 14.8% (n=70) used psychostimulants (mainly methylphenidate). Age, sex, and behavioral problems were associated with psychotropic drug use. Boys had a 1.7 (95%CI 1.1-2.4) higher probability of using psychotropic drugs, compared to girls adjusted for age and behavioral problems. Having any behavioral problem was associated with psychotropic drug use with an ARR of 2.1 (95%CI 1.3-3.3), adjusted for sex and age. The high prevalence of psychotropic drug use in children with ID is worrisome because of the lack of evidence of effectiveness (especially for behavioral problems) at this young age, and the potential of adverse drug reactions.

Background and aims To estimate the prevalence of problem and pathological gambling, gender and age-group differences in gambling types, and comorbidities with other psychiatric disorders among the Thai general population. Methods Analysis was conducted on 4,727 participants of Thailand's 2013 National Mental Health Survey, a multistage stratified cluster survey, using the Composite International Diagnostic Interview. Diagnoses of problem and pathological gambling and other psychiatric disorders were based on the DSM-IV-TR criteria with the following additional criteria for gamblers: more than 10 lifetime gambling episodes and a single year loss of at least 365 USD from gambling. Results The estimated lifetime prevalence rates of pathological and problem gambling were 0.90% [95% confidence interval (CI): 0.51-1.29] and 1.14% (95% CI: 0.58-1.70), respectively. The most popular type of gambling was playing lotteries [69.5%, standard error (SE) = 1.9], the prevalence of which was significantly higher among females and older age groups. The most common psychiatric disorders seen among pathological gamblers were alcohol abuse (57.4%), nicotine dependence (49.5%), and any drug use disorder (16.2%). Pathological gambling was highly prevalent among those who ever experienced major depressive episodes (5.5%), any drug dependence (5.1%), and intermittent explosive disorder (4.8%). The association between pathological gambling was strongest with a history of major depressive episode [adjusted odds ratio (AOR) = 10.4, 95% CI: 2.80-38.4]. Conclusion The study confirms the recognition of gambling disorders as a public health concern in Thailand and suggests a need for culturally specific preventive measures for pathological gamblers and those with a history of substance use disorders or major depression.

Objective To describe longitudinal change in risk for children remaining at home following a first-time investigation for suspected maltreatment. Study design A retrospective cohort study of children remaining at home following first-time investigation for maltreatment using a nationally representative sample of households involved with Child Protective Services (CPS). Outcomes include poverty, social support, caregiver depression, intimate partner violence (IPV), drug/alcohol dependence, corporal punishment, and child behavior problems at baseline, 18, and 36 months following first-time CPS investigation. We present longitudinal models to 1) estimate prevalence of risk factors at each timepoint and 2) examine associations between risk-specific service referrals and longitudinal change in risk factor prevalence. Results Our sample represented 1,057,056 U.S. children remaining at home following first-time investigation for maltreatment. Almost 100,000 (9.2%) children experienced out-of-home placement within 36 months. The prevalence of poverty (44.3%), poor social support (36.3%), caregiver depression (24.4%), IPV (22.1%), and internalizing (30.0%) and externalizing (35.8%) child behavior problems was above general population prevalence at baseline and remained high over the next 36 months. Referral to risk-specific services occurred in a minority of cases, but was associated with significant longitudinal reductions in IPV, drug/alcohol dependence, and externalizing child behavior problems. Conclusions Children remaining at home following a first-time investigation for maltreatment live with persistent risk factors for repeat maltreatment. Appropriate service referrals are uncommon, but may be associated with meaningful reduction in risk over time. Pediatricians and policy makers may be able to improve outcomes in these families with appropriate service provision and referrals. PMID:22480699

Our main goal was to establish whether French and Dutch adolescents differ in rates of substance-related adverse events (e.g. fights, robbery), problems with peers or socializing agents even when controlling for pattern of substance use. For problems with peers and socializing agents due to alcohol we hypothesized that, because of stronger informal control of drinking in France, French adolescents are more likely to report problems with peers and socializing agents. For adverse events due to alcohol no difference was expected after controlling for consumption patterns. For drug-related problems, the hypothesis was that, due to the more restrictive drug policy in France, French adolescents are more likely to report problems with peers, socializing agents and adverse events. Comparable surveys based on samples of adolescent schoolchildren in France (n=9646) and the Netherlands (n=4291) were used. Data were analysed using multilevel logistic regression in which school, age and gender, indicators of substance use and country were used as predictors of substance-related problems. The outcomes show that French adolescents are more likely to report problems with peers and socializing agents due to alcohol even when consumption pattern is controlled for. For adverse events due to alcohol no difference was found between French and Dutch adolescents. For drug-related problems the expected differences were found; i.e. French adolescents are more likely to report problems with peers, socializing agents and adverse events even when controlling for pattern of drug use. It is concluded that there are culturally embedded differences in the rates of some types of problems due to alcohol or drug use. With respect to alcohol use, these differences are most likely due to culturally embedded differences in the informal social control of alcohol use. The differences in rates of drug-related problems are interpreted in the context of national differences in drug policy.

Patients with bipolar disorder from the US have more early-onset illness and a greater familial loading for psychiatric problems than those from the Netherlands or Germany (abbreviated here as Europe). We hypothesized that these regional differences in illness burden would extend to the patients siblings. Outpatients with bipolar disorder gave consent for participation in a treatment outcome network and for filling out detailed questionnaires. This included a family history of unipolar depression, bipolar disorder, suicide attempt, alcohol abuse/dependence, drug abuse/dependence, and "other" illness elicited for the patients' grandparents, parents, spouses, offspring, and siblings. Problems in the siblings were examined as a function of parental and grandparental problems and the patients' adverse illness characteristics or poor prognosis factors (PPFs). Each problem in the siblings was significantly (p<0.001) more prevalent in those from the US than in those from Europe. In the US, problems in the parents and grandparents were almost uniformly associated with the same problems in the siblings, and sibling problems were related to the number of PPFs observed in the patients. Family history was based on patient report. Increased familial loading for psychiatric problems extends through 4 generations of patients with bipolar disorder from the US compared to Europe, and appears to "breed true" into the siblings of the patients. In addition to early onset, a variety of PPFs are associated with the burden of psychiatric problems in the patients' siblings and offspring. Greater attention to the multigenerational prevalence of illness in patients from the US is indicated. Copyright © 2016 Elsevier B.V. All rights reserved.

This study examined the ability of family cohesion, parental control, and parent-child attachment to prevent adolescents with a history of drug or alcohol use from experiencing subsequent problems related to their use. Data came from Wave I and Wave II of the National Longitudinal Study of Adolescent Health and included Mexican heritage and White adolescents who reported alcohol use (n = 4894, 25% prevalence) or any other drug use (n = 2875, 14% prevalence) in their lifetime. Logistic regression results indicate greater parent-child attachment predicted lower risk of experiencing drug use problems (OR = 0.87, 95% CI = 0.77-0.98) while stronger family cohesion predicted lower odds of experiencing drug- (OR = 0.82, 95% CI = 0.70-0.97) or alcohol-related (OR = 0.74, 95% CI = 0.65-0.84) problems. Parental control was also negatively associated with odds of problems related to drug use (OR = 0.93, 95% CI = 0.86-0.99) or alcohol use (OR = 0.94, 95% CI = 0.90-0.99). Results also indicated family cohesion was the only protective factor for Mexican heritage youth while family cohesion and parent-child attachment were protective among White youth. Parental control protected White female adolescents from drug use problems more than males. Mexican heritage male adolescents experienced more protection from drug problems compared to females. Findings highlight the need for prevention interventions to emphasize parent-child attachment for White youth and family cohesion for both Mexican-heritage and White youth to decrease adolescent substance users' drug- and alcohol-related problems.

Some pharmacological aspects of drug dependence.
Chesher, G B
1975-12-06
The self-administration of drugs to achieve altered states of consciousness is recognized as normal human behaviour. Community attitudes towards drug use vary according to the drug and often bear little relationship to the known pharmacological and toxicological effects of the drug. For an objective assessment of the potential dangers associated with drug use, a distinction is made between drug use and drug abuse. It is stressed that the progression from drug use to drug abuse involves social and psychological factors in addition to the pharmacological factors which are outlined in this paper. The sequential development of drug dependency is described under the headings: Induction; continued consumption; compulsive consumption; withdrawal; abstinence; reinduction. Man uses psychotropic drugs because he finds the effects rewarding. Some experimental models to explore the neurophysiological basis of the reward are described. Experiments employing inhibitors of protein synthesis suggest that the phenomena of tolerance and physical dependence involve the synthesis of new protein. It has been suggested that the new protein might be new receptor molecules for the drug or neurotransmitter substances. These new receptors might constitute a "drug memory" and provide a possible explanation for high relapse rate of drug dependent subjects. A pharmacological basis for the methadone maintenance programme of management of narcotic dependent subjects is briefly outlined.

An attempt has been made at analyzing mechanisms of formation of addiction to narcotics from the standpoint of a systemic approach to a functional organization of psychic activity. A model is proposed of the pathological functional system as the basis of narcodependence, which combines processes of two adjoining levels--those of psychic activity and of higher nervous activity. It is suggested that pathological hyperactivity of the functional structure maintaining the need for a change in the emotional state might be the basis of addiction to narcotic drugs.

The substance abuser brings his problems to the workplace. Ninety-five percent or more of all individuals experiencing alcohol-or drug-related problems are either employed or the spouse or dependent of someone who is working. It is clear we are facing a problem which transcends the boundaries of the workplace. The result in the workplace, of course, is increased costs, lower productivity, more accidents on the job, but most importantly additional suffering for the individuals involved. It is important to remember that neither GM, the UAW, nor the IUE can be expected to accept responsibility for those individuals who have the ability to control their own "wellness" and productivity. Any joint union-management substance abuse program can only be a catalyst to help individuals confront their problems. Along with the other groups and institutions concerned with these problems, GM, in cooperation with the UAW, IUE, and the other unions that represent our employees, is trying to help individuals with addictive diseases confront and obtain treatment for their problems. We believe our programs are moving in the right direction and will continue to make progress.

Background Illicit drug use is an important public health problem. Identifying conditions that coexist with illicit drug use is necessary for planning health services. This study described the prevalence and factors associated with social and health problems among clients seeking treatment for illicit drug use. Methods We carried out cross-sectional analyses of baseline data of 2526 clients who sought treatment for illicit drug use at Helsinki Deaconess Institute between 2001 and 2008. At the clients’ first visit, trained clinicians conducted face-to-face interviews using a structured questionnaire. Logistic regression was used to compute adjusted odds ratios (AORs) and 95% confidence intervals (CIs) for factors associated with social and health problems. Results The mean age of the clients was 25 years, 21% (n = 519) were homeless, 54% (n = 1363) were unemployed and 7% (n = 183) had experienced threats of violence. Half of the clients (50%, n = 1258) were self-referred and 31% (n = 788) used opiates as their primary drugs of abuse. Hepatitis C (25%, n = 630) was more prevalent than other infectious diseases and depressive symptoms (59%, n = 1490) were the most prevalent psychological problems. Clients who were self-referred to treatment were most likely than others to report social problems (AOR = 1.86; 95% CI = 1.50–2.30) and psychological problems (AOR = 1.51; 95% CI = 1.23–1.85). Using opiates as primary drugs of abuse was the strongest factor associated with infectious diseases (AOR = 3.89; 95% CI = 1.32–11.46) and for reporting a combination of social and health problems (AOR = 3.24; 95% CI = 1.58–6.65). Conclusion The existence of illicit drug use with other social and health problems could lead to increased utilisation and cost of healthcare services. Coexisting social and health problems may interfere with clients’ treatment response. Our findings support the call for integration of relevant social, medical and mental health support services within drug treatment programmes. PMID:23617549

Drug-addicted patients exhibit various personality disorders that interfere with their adaptation to society, as well as their ability to participate in the rehabilitation process. The Latvian Rehabilitation Programme for drug addicts includes social problem-solving training to help patients reintegrate into society. However, the role of personality disorders has not been investigated in relation to this process. The aim of the study is to assess whether personality disorders predict changes in dimensions of social problem-solving after 6 months of rehabilitation for drug-addicted patients. The sample of this study consists of 31 drug-addicted patients from the Latvian rehabilitation centres aged 21-35 (females 21%, males 79%). Two inventories are used: the Social Problem-Solving Inventory--Revised (SPSI-R) and Millon(TM) Clinical Multiaxial Inventory--III (MCMI-III) adapted into Russian. Results of the study indicated that some MCMI-III personality disorders (Schizoid and Histrionic) negatively predicted SPSI-R Positive problem orientation, and narcissistic disorder positively predicted SPSI-R Avoidance style after 6 months in the Latvian Rehabilitation Programme. The other personality disorders did not predict social problem-solving dimensions. The results of the study suggest that some personality disorders are related to changes in social problem-solving dimensions for drug-addicted patients. Hence, it is important to consider the implications of particular personality disorders to facilitate the implementation of social problem-solving rehabilitation programmes.

The overexpression of multidrug resistance (MDR) systems on the gram negative bacteria causes serious problems for treatment of bacterial infectious diseases. The system effectively pumps the antibiotic drugs out of the bacterial cells. During the pumping process one of the MDR components, AcrB undergoes a series of large-scale conformational changes which are responsible for drug recognition, binding and expelling. All-atom simulations are unable to capture those conformational changes because of computational cost. Here, we implement a hybrid coarse-grained force field that couples the united-atom protein models with the coarse-grained MARTINI water/lipid, to investigate the proton-dependent conformational changes of AcrB. The simulation results in early stage ( 100 ns) of proton-dependent conformational changes agree with all-atom simulations, validating the coarse-grained model. The coarse-grained force field allows us to explore the process in microsecond simulations. Starting from the crystal structures of Access(A)/Binding(B)/Extrusion(E) monomers in AcrB, we find that deprotonation of Asp407 and Asp408 in monomer E causes a series of large-scale conformational changes from ABE to AAA in absence of drug molecules, which is consistent with experimental findings.

Responses to hallucinogenic drugs, such as psilocybin, are believed to be critically dependent on the user's personality, current mood state, drug pre-experiences, expectancies, and social and environmental variables. However, little is known about the order of importance of these variables and their effect sizes in comparison to drug dose. Hence, this study investigated the effects of 24 predictor variables, including age, sex, education, personality traits, drug pre-experience, mental state before drug intake, experimental setting, and drug dose on the acute response to psilocybin. The analysis was based on the pooled data of 23 controlled experimental studies involving 409 psilocybin administrations to 261 healthy volunteers. Multiple linear mixed effects models were fitted for each of 15 response variables. Although drug dose was clearly the most important predictor for all measured response variables, several non-pharmacological variables significantly contributed to the effects of psilocybin. Specifically, having a high score in the personality trait of Absorption, being in an emotionally excitable and active state immediately before drug intake, and having experienced few psychological problems in past weeks were most strongly associated with pleasant and mystical-type experiences, whereas high Emotional Excitability, low age, and an experimental setting involving positron emission tomography most strongly predicted unpleasant and/or anxious reactions to psilocybin. The results confirm that non-pharmacological variables play an important role in the effects of psilocybin. PMID:22363492

The media has portrayed African Americans as drug users and criminals. The purpose of this study is to test the assumption that low-income African Americans use more alcohol, nicotine, marijuana, and illicit drugs than other racial groups using data from the 2005 National Survey on Drug Use and Health to compare drug abuse and dependence across low income racial groups (N = 20,172). Most respondents were white, female, and older than 26 years of age. The majority completed high school and reported annual family incomes between $10,000 and $19,000. Few participants reported receiving public assistance. Drug abuse and dependence rates varied across drug type and across race. Drug dependence and abuse were measured using the Nicotine Dependence Syndrome Scale and criteria from the Diagnostic and Statistical Manual of Mental Disorders. Hierarchical regression was conducted to examine the level of association between racial background and drug abuse and dependence after controlling for age and gender. Results reveal that the assumption of high drug and alcohol use and abuse rates among low-income African Americans should be, at best, reexamined. This study has significant implications for both policy and social work practice because it breaks down normalized and biased assumptions of low-income African American drug use.

The problem of drug shortages has been reported worldwide, gaining prominence in multiple domains and several countries in recent years. The aim of the study was to analyze, characterise and assess this problem in Belgium and France, while also adopting a wider perspective from the European Union. A qualitative methodological approach was employed, including semi-structured interviews with the representatives of respective national health authorities, pharmaceutical companies and wholesalers, as well as hospital and community pharmacists. The research was conducted in early 2014. Four themes, which were identified through the interviews, were addressed in the paper, i.e. a) defining drug shortages, b) their dynamics and perception, c) their determinants, d) the role of the European and national institutions in coping with the problem. Three groups of determinants of drug shortages were identified throughout this study: manufacturing problems, distribution and supply problems, and problems related to economic aspects. Currently, the Member States of the European Union are striving to resolve the problem very much on their own, although a far more focused and dedicated collaboration may well prove instrumental in coping with drug shortages throughout Europe more effectively. To the best of the authors’ knowledge, this is the first qualitative study to investigate the characteristics, key determinants, and the problem drivers of drug shortages, focusing on this particular group of countries, while also adopting the European Union’s perspective.

Objective To examine predictors of opioid abstinence in buprenorphine/naloxone (Bup/Nal) assisted psychosocial treatment for opioid dependent youth Method Secondary analyses of data from 152 youth (ages 15–21) randomly assigned to 12 weeks of extended Bup/Nal therapy or up to 2 weeks of Bup/Nal detoxification, both with weekly individual and group drug counseling. Logistic regression models were constructed to identify baseline and during-treatment predictors of opioid positive urines (OPU) at week-12. Predictors were selected based on significance or trend toward significance (i.e. p<0.1) and backward stepwise selection was used, controlling for treatment group, to produce final independent predictors at p ≤ 0.05. Results Youth presenting to treatment with past 30-day injection drug use (IDU) and more active medical/psychiatric problems were less likely to have a week-12 OPU. Those with early treatment opioid abstinence (i.e. weeks 1 and 2); and those who received additional non-study treatments during the study were less likely to have a week-12 OPU; and those not completing 12 weeks of treatment were more likely to have an OPU. Conclusions Youth with advanced illness (i.e. reporting IDU and additional health problems), and those receiving ancillary treatments to augment study treatment were more likely to have lower opioid use. Treatment success in the first 2 weeks and completion of 12 weeks of treatment were associated with lower rates of OPU. These findings suggest that youth with advanced illness respond well to Bup/Nal treatment, and identify options for tailoring treatment for opioid-dependent youth presenting at community-based settings.

In human epilepsy, pharmacoresistance to antiepileptic drug therapy is a major problem affecting ~30% of patients with epilepsy. Many classical antiepileptic drugs target voltage-gated sodium channels, and their potent activity in inhibiting high-frequency firing has been attributed to their strong use-dependent blocking action. In chronic epilepsy, a loss of use-dependent block has emerged as a potential cellular mechanism of pharmacoresistance for anticonvulsants acting on voltage-gated sodium channels. The anticonvulsant drug lacosamide (LCM) also targets sodium channels, but has been shown to preferentially affect sodium channel slow inactivation processes, in contrast to most other anticonvulsants. We used whole-cell voltage clamp recordings in acutely isolated cells to investigate the effects of LCM on transient Na + currents. Furthermore, we used whole-cell current clamp recordings to assess effects on repetitive action potential firing in hippocampal slices. We show here that LCM exerts its effects primarily via shifting the slow inactivation voltage dependence to more hyperpolarized potentials in hippocampal dentate granule cells from control and epileptic rats, and from patients with epilepsy. It is important to note that this activity of LCM was maintained in chronic experimental and human epilepsy. Furthermore, we demonstrate that the efficacy of LCM in inhibiting high-frequency firing is undiminished in chronic experimental and human epilepsy. Taken together, these results show that LCM exhibits maintained efficacy in chronic epilepsy, in contrast to conventional use-dependent sodium channel blockers such as carbamazepine. They also establish that targeting slow inactivation may be a promising strategy for overcoming target mechanisms of pharmacoresistance.

This study aimed to evaluate the association between substance use (alcohol, tobacco, and illicit drugs) and family problems among 965 adolescents from 50 public schools in two cities in São Paulo State, Brazil, in 2007. The Drug Use Screening Inventory (DUSI) was used for data collection. Use of alcohol, tobacco, and illicit drugs was associated with a negative assessment of the family relationship, lack of monitoring/support, and psychoactive substance use by family members (p < 0.05). Adolescents that reported having used alcohol, tobacco, and illicit drugs had more family problems than those who did not consume any substance (p < 0.001). Adolescents that used alcohol and tobacco (p = 0.028) and illicit drugs (p < 0.001) reported having more family problems than those who used only alcohol. The results highlight the importance of awareness of alcohol and tobacco use by adolescents, since such use was associated with significant family impairments, similar to illicit drug use.

More than 10 years has passed since 1995 when the third epidemic of methamphetamine abuse started in Japan. We are now still in the third epidemic of methamphetamine abuse, thought the current situation of drug abuse/dependence has obviously changed from previously. Considering several kinds of nationwide surveys and censuses, the authors summarized the change as follows: a) obvious decrease in solvent abuse/dependence, b) stabilization of methamphetamine abuse/dependence, c) increase in abuse of such drugs as cannabis or MDMA which don't have high potential to cause drug-induced psychosis, and d) emergence of non-regulatory drugs represented by designer drugs. These imply the change a) from "hard drugs" to "soft drugs", b) from Japanese unique situation which is symbolized by solvent abuse to Western situation which is symbolized by cannabis abuse, and c) from "illicit drugs" to "non-regulatory drugs". These characteristics reveal that there is the limitation to the Japanese Government policy which has tried to control the drug issue mainly as criminal cases for many years and that it is time now to change its policy. The authors stress the necessities of development of medical treatment targeting drug dependence and of its social support system.

The main problem of using human corpus cavernosum (HCC) tissue to perform bioassay is linked to its limited availability further complicated by the heterogeneous source of the tissues used. Here, we show that gender reassignment is a reliable source of human tissue without major ethical problems. Indeed, the entire corpus cavernosum is obtained from the surgery procedure, which allows creating a standardized procedure to prepare HCC strip. In addition, human tissue, if kept in the fridge in the condition described, does not loose its ability to contract to phenylephrine (PE; alpha agonist), angiotensin II (AG II) and KCl up to 4 days. Furthermore, once contracted with PE, HCC relaxes to acetylcholine (endothelium-dependent mechanism); sodium nitroprusside (endothelium-independent mechanism); cromakalim (CRK), a K(ATP) channel opener; or alprostadil, a synthetic PGE2 (ALPR). In conclusion, we have standardized a procedure that allows the use of HCC strips to evaluate drug activity and/or to study pathophysiological mechanisms with an intact functional human tissue up to 4 days from the surgery procedure.

The neuraminidase (NA) and M2 proton channel of influenza virus are the drug-targeting proteins, based on which several drugs were developed. However these once powerful drugs encountered drug-resistant problem to the H5N1 and H1N1 flu. To address this problem, the computational 3D structures of NA and M2 proteins of 2009-H1N1 influenza virus were built using the molecular modeling technique and computational chemistry method. Based on the models the structure features of NA and M2 proteins were analyzed, the docking structures of drug-protein complexes were computed, and the residue mutations were annotated. The results may help to solve the drug-resistant problem and stimulate designing more effective drugs against 2009-H1N1 influenza pandemic.

An estimated 3% of the United States population deliberately misuse or abuse psychoactive medications, with severe consequences. According to the National Institute on Drug Abuse, more than half of patients who sought treatment or died of drug-related medical problems in 1989 were abusing prescription drugs. Physicians who contribute to this problem have been described by the American Medical Association as dishonest--willfully misprescribing for purposes of abuse, usually for profit; disabled by personal problems with drugs or alcohol; dated in their knowledge of current pharmacology or therapeutics; or deceived by various patient-initiated fraudulent approaches. Even physicians who do not meet any of these descriptions must guard against contributing to prescription drug abuse through injudicious prescribing, inadequate safeguarding of prescription forms or drug supplies, or acquiescing to the demands or ruses used to obtain drugs for other than medical purposes.

Previous work has highlighted the adverse consequences of early-onset cannabis use. However, little is known about the predictors and effects of early-onset amphetamine use. We set out to examine these issues using a representative cohort of young people followed-up over 11 years in Victoria, Australia. A stratified, random sample of 1943 adolescents was recruited from secondary schools across Victoria at age 14-15 years. This cohort was interviewed on eight occasions until the age of 24-25 years (78% follow-up at that age). Cross-sectional associations were assessed using logistic regression with allowance for repeated measures. Both proportional hazards models and logistic regression models were used to assess prospective associations. Approximately 7% of the sample had used amphetamines by the age of 17 years. Amphetamine use by this age was associated with poorer mental health and other drug use. The incidence of amphetamine use during the teenage years was predicted by heavier drug use and by mental health problems. By young adulthood (age 24-25 years), adolescent amphetamine users were more likely to meet criteria for dependence upon a range of drugs, to have greater psychological morbidity and to have some limitations in educational attainment. Most of these associations were not sustained after adjustment for early-onset cannabis use. Young people in Australia who begin amphetamine use by age 17 years are at increased risk for a range of mental health, substance use and psychosocial problems in young adulthood. However, these problems are largely accounted for by their even earlier-onset cannabis use.

Opioid painkiller dependence is a growing problem and best-practice management is not well defined. We report a case of a young woman exhibiting dependence on codeine, originally prescribed for myalgic encephalopathy, after escalating use over a 10-year period. In 2012, a consultation with a new general practitioner, who had extensive experience of patients with substance abuse, revealed the underlying dependence. After building trust for 6 months, she was able to admit to medication abuse, and was referred to the community drug and alcohol team. On presentation to the team, the patient had no pain issues and the dihydrocodeine use—600 tablets/week—solely reflected her dependence. The patient successfully underwent rapid induction with buprenorphine/naloxone as opioid substitution treatment over 2 days. She is currently stable, engaged with recovery support services and psychosocial counselling, and has just returned to work. She is maintained on a therapeutic dose of buprenorphine 10 mg/naloxone 2.5 mg. PMID:25432908

To examine the influence of undocumented immigration in the United States on 4 different metrics of drug and alcohol problems: drug arrests, drug overdose fatalities, driving under the influence (DUI) arrests, and DUI deaths. We combined newly developed state-level estimates of the undocumented population between 1990 and 2014 from the Center for Migration Studies with arrest data from the Federal Bureau of Investigation Uniform Crime Reports and fatality information from the Fatality Analysis Reporting System and the Centers for Disease Control and Prevention Underlying Cause of Death database. We used fixed-effects regression models to examine the longitudinal association between increased undocumented immigration and drug problems and drunk driving. Increased undocumented immigration was significantly associated with reductions in drug arrests, drug overdose deaths, and DUI arrests, net of other factors. There was no significant relationship between increased undocumented immigration and DUI deaths. This study provides evidence that undocumented immigration has not increased the prevalence of drug or alcohol problems, but may be associated with reductions in these public health concerns.
Young Adult Ecstasy Users’ Enhancement of the Effects of Their Ecstasy Use
Klein, Hugh; Elifson, Kirk W.; Sterk, Claire E.
2013-01-01
In this paper, we examine drug effect-enhancing behaviors practiced by young adult users of the drug, ecstasy. Between August 2002 and August 2004, 283 face-to-face interviews were conducted with active ecstasy users. Study participants were recruited in the Atlanta, Georgia metropolitan area using a targeted sampling approach. The large majority of study participants (87%) engaged in at least one behavior specifically designed to bolster the effects of their ecstasy use, with 61% of the study participants reporting having engaged in at least three such behaviors during the past 30 days. Taking steps to boost one’s ecstasy-related high was associated with binging on ecstasy and a variety of adverse outcomes, such as experiencing a greater number of negative consequences resulting from ecstasy use and experiencing more ecstasy-related drug dependency symptoms. Multivariate analysis revealed several factors associated with greater involvement in effects-boosting behaviors, including race (not being African American), spending time with other drug users, using ecstasy for its touch-enhancing qualities, enjoyment of the music-and-ecstasy-use experience, and childhood maltreatment experiences. The implications of these findings for treatment, prevention, and intervention of drug problems among ecstasy users are discussed. PMID:19705673

Tuberculosis (TB) is still a major public health problem in the world, with many factors contributing to this burden, including poor living conditions, overcrowding, poverty, malnutrition, illiteracy, and rapid spread of human immunodeficiency virus infection. Cutaneous tuberculosis is a less common form of extrapulmonary tuberculosis, and in this paucibacillary form the diagnosis depends on histopathology, tuberculin positivity, and response to treatment. The diagnosis is even more difficult in cases with drug resistant Mycobacterium tuberculosis due to lack of awareness and lack of facilities to diagnose drug resistant tuberculosis. In this article, we describe an unusual case of multidrug resistant lupus vulgaris (LV), in a 34-year-old male who responded to anti-tubercular treatment (ATT) initially, but developed recurrent disease which failed to respond to standard four-drug ATT; subsequently, tissue culture showed growth of multidrug resistant M. tuberculosis. Subsequently, he also developed cutaneous squamous cell carcinoma. This article aims to exemplify a grave complication that can occur in long-standing case of LV, the limitations faced by clinicians in developing countries where tuberculosis is endemic, and classical methods of proving drug resistance are generally unavailable or fail.

Human engineered heart tissue as a model system for drug testing.
Eder, Alexandra; Vollert, Ingra; Hansen, Arne; Eschenhagen, Thomas
2016-01-15
Drug development is time- and cost-intensive and, despite extensive efforts, still hampered by the limited value of current preclinical test systems to predict side effects, including proarrhythmic and cardiotoxic effects in clinical practice. Part of the problem may be related to species-dependent differences in cardiomyocyte biology. Therefore, the event of readily available human induced pluripotent stem cell (hiPSC)-derived cardiomyocytes (CM) has raised hopes that this human test bed could improve preclinical safety pharmacology as well as drug discovery approaches. However, hiPSC-CM are immature and exhibit peculiarities in terms of ion channel function, gene expression, structural organization and functional responses to drugs that limit their present usefulness. Current efforts are thus directed towards improving hiPSC-CM maturity and high-content readouts. Culturing hiPSC-CM as 3-dimensional engineered heart tissue (EHT) improves CM maturity and anisotropy and, in a 24-well format using silicone racks, enables automated, multiplexed high content readout of contractile function. This review summarizes the principal technology and focuses on advantages and disadvantages of this technology and its potential for preclinical drug screening. Copyright © 2015 Elsevier B.V.

Measurements of Deposition, Lung Surface Area and Lung Fluid for Simulation of Inhaled Compounds
Fröhlich, Eleonore; Mercuri, Annalisa; Wu, Shengqian; Salar-Behzadi, Sharareh
2016-01-01
Modern strategies in drug development employ in silico techniques in the design of compounds as well as estimations of pharmacokinetics, pharmacodynamics and toxicity parameters. The quality of the results depends on software algorithm, data library and input data. Compared to simulations of absorption, distribution, metabolism, excretion, and toxicity of oral drug compounds, relatively few studies report predictions of pharmacokinetics and pharmacodynamics of inhaled substances. For calculation of the drug concentration at the absorption site, the pulmonary epithelium, physiological parameters such as lung surface and distribution volume (lung lining fluid) have to be known. These parameters can only be determined by invasive techniques and by postmortem studies. Very different values have been reported in the literature. This review addresses the state of software programs for simulation of orally inhaled substances and focuses on problems in the determination of particle deposition, lung surface and of lung lining fluid. The different surface areas for deposition and for drug absorption are difficult to include directly into the simulations. As drug levels are influenced by multiple parameters the role of single parameters in the simulations cannot be identified easily. PMID:27445817

Three groups of children from low-income, urban environments were examined to determine the effects of prenatal drug exposure (PDE) and caregiving environment on sustained visual attention (SVA) at 7 years of age. Drug-exposed children remaining in maternal care (n = 43), drug-exposed children placed in nonmaternal care (n = 45), and community comparison (CC) children (n = 56) were administered a battery of neurocognitive tests, including the Conners' Continuous Performance Test (CPT). PDE children remaining in maternal care displayed more omission errors than CC children. PDE children in nonmaternal care had intermediate scores that did not differ significantly from PDE children in maternal care or CC children. There were no group differences with respect to commission errors or reaction time. CPT errors of omission and commission were significantly correlated with parent-reported attention problems and academic achievement scores. PDE in the context of care provided by a maternal caregiver with persistent drug use patterns may contribute to problems in children's SVA at school-age. As parental drug abuse can interfere with the provision of early care, children raised in a drug-using context may be highly vulnerable to problems with self-regulation, including sustained attention. SVA problems may contribute to subsequent academic and behavioral problems as demands for concentration and sustained effort increase throughout childhood. Children who have been prenatally exposed to drugs or raised in a drug-using household may benefit from early intervention services to avoid problems in SVA that may interfere with subsequent neurocognitive functioning and academic performance.

Illicit and prescription drug use disorders are two to four times more prevalent among Aboriginal peoples in North America than the general population. Research suggests Aboriginal cultural participation may be protective against substance use problems in rural and remote Aboriginal communities. As Aboriginal peoples continue to urbanize rapidly around the globe, the role traditional Aboriginal beliefs and practices may play in reducing or even preventing substance use problems in cities is becoming increasingly relevant, and is the focus of the present study. Mainstream acculturation was also examined. Data were collected via in-person surveys with a community-based sample of Aboriginal adults living in a mid-sized city in western Canada (N = 381) in 2010. Associations were analysed using two sets of bootstrapped linear regression models adjusted for confounders with continuous illicit and prescription drug problem scores as outcomes. Psychological mechanisms that may explain why traditional culture is protective for Aboriginal peoples were examined using the cross-products of coefficients mediation method. The extent to which culture served as a resilience factor was examined via interaction testing. Results indicate Aboriginal enculturation was a protective factor associated with reduced 12-month illicit drug problems and 12-month prescription drug problems among Aboriginal adults in an urban setting. Increased self-esteem partially explained why cultural participation was protective. Cultural participation also promoted resilience by reducing the effects of high school incompletion on drug problems. In contrast, mainstream acculturation was not associated with illicit drug problems and served as a risk factor for prescription drug problems in this urban sample. Findings encourage the growth of programs and services that support Aboriginal peoples who strive to maintain their cultural traditions within cities, and further studies that examine how Aboriginal cultural practices and beliefs may promote and protect Aboriginal health in an urban environment.

Mediating the distal crime-drug relationship with proximal reactive criminal thinking.
Walters, Glenn D
2016-02-01
This article describes the results of a study designed to test whether reactive criminal thinking (RCT) does a better job of mediating the crime → drug relationship than it does mediating the drug → crime relationship after the direct effects of crime on drug use/dependency and of drug use/dependency on crime have been rendered nonsignificant by control variables. All 1,170 male members of the Pathways to Desistance study (Mulvey, 2012) served as participants in the current investigation. As predicted, the total (unmediated) effects of crime on substance use/dependence and of substance use/dependence on crime were nonsignificant when key demographic and third variables were controlled, although the indirect (RCT-mediated) effect of crime on drug use was significant. Proactive criminal thinking (PCT), by comparison, failed to mediate either relationship. The RCT continued to mediate the crime → drug relationship and the PCT continued to not mediate either relationship when more specific forms of offending (aggressive, income) and substance use/dependence (drug use, substance-use dependency symptoms) were analyzed. This offers preliminary support for the notion that even when the total crime-drug effect is nonsignificant the indirect path from crime to reactive criminal thinking to drugs can still be significant. Based on these results, it is concluded that mediation by proximal reactive criminal thinking is a mechanism by which distal measures of crime and drug use/dependence are connected.

Norepinephrine and Stimulant Addiction
Sofuoglu, Mehmet; Sewell, R. Andrew
2008-01-01
No pharmacotherapies are approved for stimulant use disorders, which are an important public health problem. Stimulants increase synaptic levels of the monoamines dopamine (DA), serotonin (5-HT), and norepinephrine (NE). Stimulant reward is attributable mostly to increased DA in the reward circuitry, although DA stimulation alone cannot explain the rewarding effects of stimulants. The noradrenergic system, which uses NE as the main chemical messenger, serves multiple brain functions including arousal, attention, mood, learning, memory, and stress response. In preclinical models of addiction, NE is critically involved in mediating stimulant effects including sensitization, drug discrimination, and reinstatement of drug seeking. In clinical studies, adrenergic blockers have shown promise as treatments for cocaine abuse and dependence, especially in patients experiencing severe withdrawal symptoms. Disulfiram, which blocks NE synthesis, increased the number of cocaine-negative urines in five randomized clinical trials. Lofexidine, an α2-adrenergic agonist, reduces the craving induced by stress and drug cues in drug users. In addition, the norepinephrine transporter (NET) inhibitor atomoxetine attenuates some of d-amphetamine’s subjective and physiological effects in humans. These findings warrant further studies evaluating noradrenergic medications as treatments for stimulant addiction. PMID:18811678

Mutant mice simulating human CNS disorders are used as models for therapeutic drug development. Drug evaluation requires a coherent correlation between behavioral phenotype and drug status. Variations in behavioral responses could mask such correlations, a problem highlighted by the three-site studies of Crabbe et al. (1999) and Wahlsten et al. (2003a). Factors contributing to variation are considered, focusing on differences between individual animals. Genetic differences due to minisatellite variation suggest that each mouse is genetically distinct. Effects during gestation, including maternal stress, influence later life behavior; while endocrine exchanges between fetus and parent, and between male and female fetuses dependent on intrauterine position, also contribute. Pre and perinatal nutrition and maternal attention also play a role. In adults, endocrine cyclicity in females is a recognized source of behavioral diversity. Notably, there is increasing recognition that groups of wild and laboratory mice have complex social structures, illustrated through consideration of Crowcroft (1966). Dominance status can markedly modify behavior in test paradigms addressing anxiety, locomotion and aggressiveness, to an extent comparable to mutation or drug status. Understanding how such effects amplify the behavioral spectrum displayed by otherwise identical animals will improve testing.

To describe the self-reported history of health service utilization and help-seeking to those who are drug-dependent in the period of time prior to imprisonment. A cross-section survey of 3142 sentenced or remand prisoners in English prisons completed private, face-to-face interviews with trained Office for National Statistics staff covering a full structured psychiatric assessment interview. Specific questions about service utilization prior to imprisonment were included, as were questions on patterns of drug use and dependence prior to imprisonment. Receipt of any form of help was demographically most strongly associated with being older, white and female. Women were about twice as likely as men to report having received help for mental or emotional problems. Older age was also consistently associated with greater levels of reporting having received help, for both genders but only for use of general practitioners. Being black was strongly associated with reduced likelihood of receiving help and this was maintained after adjusting for other sociodemographic variables. Opioid dependence alone or opioid dependence with stimulant dependence, psychiatric disorder alone and probable psychosis were all most predictive of service use in the 12 months prior to imprisonment. In the year prior to imprisonment, the majority of mental health needs of these individual prisoners were not able to access help prior to imprisonment. Future strategies should aim for better health access before, during and after imprisonment.
Illicit Anabolic-Androgenic Steroid Use
Kanayama, Gen; Hudson, James I.; Pope, Harrison G.
2009-01-01
The anabolic-androgenic steroids (AAS) are a family of hormones that includes testosterone and its derivatives. These substances have been used by elite athletes since the 1950s, but they did not become widespread drugs of abuse in the general population until the 1980s. Thus, knowledge of the medical and behavioral effects of illicit AAS use is still evolving. Surveys suggest that many millions of boys and men, primarily in Western countries, have abused AAS to enhance athletic performance or personal appearance. AAS use among girls and women is much less common. Taken in supraphysiologic doses, AAS show various long-term adverse medical effects, especially cardiovascular toxicity. Behavioral effects of AAS include hypomanic or manic symptoms, sometimes accompanied by aggression or violence, which usually occur while taking AAS, and depressive symptoms occurring during AAS withdrawal. However, these symptoms are idiosyncratic and afflict only a minority of illicit users; the mechanism of these idiosyncratic responses remains unclear. AAS users may also ingest a range of other illicit drugs, including both “body-image” drugs to enhance physical appearance or performance, and classical drugs of abuse. In particular, AAS users appear particularly prone to opioid use. There may well be a biological basis for this association, since both human and animal data suggest that AAS and opioids may share similar brain mechanisms. Finally, AAS may cause a dependence syndrome in a substantial minority of users. AAS dependence may pose a growing public health problem in future years, but remains little studied. PMID:19769977
Continuous infusion of antibiotics in critically ill patients.
Smuszkiewicz, Piotr; Szałek, Edyta; Tomczak, Hanna; Grześkowiak, Edmund
2013-02-01
Antibiotics are the most commonly used drugs in intensive care unit patients and their supply should be based on pharmacokinetic/pharmacodynamic rules. The changes that occur in septic patients who are critically ill may be responsible for subtherapeutic antibiotic concentrations leading to poorer clinical outcomes. Evolving in time the disturbed pathophysiology in severe sepsis (high cardiac output, glomerular hyperfiltration) and therapeutic interventions (e.g. haemodynamically active drugs, mechanical ventilation, renal replacement therapy) alters antibiotic pharmacokinetics mainly through an increase in the volume of distribution and altered drug clearance. The lack of new and efficacious drugs and increased bacterial resistance are current problems of contemporary antibiotic therapy. Although intermittent administration is a standard clinical practice, alternative methods of antibiotic administration are sought, which may potentialise effects and reduce toxicity as well as contribute to inhibition of bacterial resistance. A wide range of studies prove that the application of continuous infusion of time-dependent antibiotics (beta-lactams, glycopeptides) is more rational than standard intermittent administration. However, there are also studies which do not confirm the advantage of one method over the other. In spite of controversy the continuous administration of this group of antibiotics is common practice, because the results of both studies point to the higher efficacy of this method in critically ill patients. Authors reviewed the literature to determine whether any clinical benefits exist for administration of time-dependent antibiotics by continuous infusion. Definite specification of the clinical advantage of administration this way over standard dosage requires a large-scale multi-centre randomised controlled trial.
Substance abuse among Iranian high school students.
Momtazi, Saeed; Rawson, Richard
2010-05-01
In this study, we reviewed data on drug use among high school students in Iran. Published epidemiological studies in international and domestic journals show that drug use/abuse is a serious mental health problem in Iran. There is cultural support for opium in Iran and also there is cultural tolerance for tobacco smoking, especially as water pipe smoking in Iranian families. Alcohol, opium and cannabis are the most frequently used illicit drugs, but there are new emerging problems with anabolic steroids, ecstasy and stimulant substances, such as crystal methamphetamine. There is a serious drug abuse problem among Iranian high school students. It could be due to role modeling by parents - mainly fathers - and also cultural tolerance of some substances. Early onset of tobacco smoking, with a daily use rate between 4.4 and 12.8% in high school students, is an important risk factor for other drug abuse problems. Use of all types of drugs, except prescription drugs, is more prevalent among boys. Alcohol is the most frequently abused substance, with a lifetime rate of at least 9.9%. Lifetime rates of opiate use - mostly opium - was between 1.2 and 8.6% in different parts of the country. As drug abuse is a frequent problem among Iranian high school students, it is necessary to design and implement drug prevention programs to protect them. Such programs, including life skills training and drug education, have been operating in recent years for Iranian students from kindergarten to the university level.

This paper presents two replications of a heuristic model for measuring environment in studies of gene-environment interplay in the etiology of young adult problem behaviors. Data were drawn from two longitudinal, U.S. studies of the etiology of substance use and related behaviors: the Raising Healthy Children study (RHC; N=1040, 47% female) and the Minnesota Twin Family Study (MTFS; N=1512, 50% female). RHC included a Pacific Northwest, school-based, community sample. MTFS included twins identified from state birth records in Minnesota. Both studies included commensurate measures of general family environment and family substance-specific environments in adolescence (RHC ages 10-18; MTFS age 18), as well as young adult nicotine dependence, alcohol and illicit drug use disorders, HIV sexual risk behavior, and antisocial behavior (RHC ages 24, 25; MTFS age 25). Results from the two samples were highly consistent and largely supported the heuristic model proposed by Bailey et al. (2011). Adolescent general family environment, family smoking environment, and family drinking environment predicted shared variance in problem behaviors in young adulthood. Family smoking environment predicted unique variance in young adult nicotine dependence. Family drinking environment did not appear to predict unique variance in young adult alcohol use disorder. Organizing environmental predictors and outcomes into general and substance-specific measures provides a useful way forward in modeling complex environments and phenotypes. Results suggest that programs aimed at preventing young adult problem behaviors should target general family environment and family smoking and drinking environments in adolescence.

This paper proposes a novel hypnosis control method using Auditory Evoked Potential Index (aepEX) as a hypnosis index. In order to avoid side effects of an anesthetic drug, it is desirable to reduce the amount of an anesthetic drug during surgery. For this purpose many studies of hypnosis control systems have been done. Most of them use Bispectral Index (BIS), another hypnosis index, but it has problems of dependence on anesthetic drugs and nonsmooth change near some particular values. On the other hand, aepEX has an ability of clear distinction between patient consciousness and unconsciousness and independence of anesthetic drugs. The control method proposed in this paper consists of two elements: estimating the minimum effect-site concentration for maintaining appropriate hypnosis and adjusting infusion rate of an anesthetic drug, propofol, using model predictive control. The minimum effect-site concentration is estimated utilizing the property of aepEX pharmacodynamics. The infusion rate of propofol is adjusted so that effect-site concentration of propofol may be kept near and always above the minimum effect-site concentration. Simulation results of hypnosis control using the proposed method show that the minimum concentration can be estimated appropriately and that the proposed control method can maintain hypnosis adequately and reduce the total infusion amount of propofol.
Nasal-nanotechnology: revolution for efficient therapeutics delivery.
Kumar, Amrish; Pandey, Aditya Nath; Jain, Sunil Kumar
2016-01-01
In recent years, nanotechnology-based delivery systems have gained interest to overcome the problems of restricted absorption of therapeutic agents from the nasal cavity, depending upon the physicochemical properties of the drug and physiological properties of the human nose. The well-tolerated and non-invasive nasal drug delivery when combined with the nanotechnology-based novel formulations and carriers, opens the way for the effective systemic and brain targeting delivery of various therapeutic agents. To accomplish competent drug delivery, it is imperative to recognize the interactions among the nanomaterials and the nasal biological environment, targeting cell-surface receptors, drug release, multiple drug administration, stability of therapeutic agents and molecular mechanisms of cell signaling involved in patho-biology of the disease under consideration. Quite a few systems have been successfully formulated using nanomaterials for intranasal (IN) delivery. Carbon nanotubes (CNTs), chitosan, polylactic-co-glycolic acid (PLGA) and PLGA-based nanosystems have also been studied in vitro and in vivo for the delivery of several therapeutic agents which shown promising concentrations in the brain after nasal administration. The use of nanomaterials including peptide-based nanotubes and nanogels (NGs) for vaccine delivery via nasal route is a new approach to control the disease progression. In this review, the recent developments in nanotechnology utilized for nasal drug delivery have been discussed.

The unmet need for effective antivirals against potential agents of bioterrorism and emerging infections is obvious; however, the challenges to develop such drugs are daunting. Even with the passage of Project BioShield and more recently the BARDA legislation, there is still not a clear market for these types of drugs and limited federal funding available to support expensive drug development studies. SIGA Technologies, Inc. is a small biotech company committed to developing novel products for the prevention and treatment of severe infectious diseases, with an emphasis on products for diseases that could result from bioterrorism. Through trials and error SIGA has developed an approach to this problem in order to establish the infrastructure necessary to successfully advance new antiviral drugs from the discovery stage on through to licensure. The approach that we have taken to drug development is biology driven and dependent on a dispersive development model utilizing essential collaborations with academic, federal, and private sector partners. This consortium approach requires success in acquiring grants and contracts as well as iterative communication with the government and regulatory agencies. However, it can work as evidenced by the rapid progress of our lead antiviral against smallpox, ST-246, and should serve as the template for development of new antivirals against important biological pathogens.

The authors tested how adverse childhood experiences (child maltreatment and parent alcohol- and drug-related problems) and adult polydrug use (as a mediator) predict poor parenting in a community sample (237 mothers and 81 fathers). These relationships were framed within several theoretical perspectives, including observational learning, impaired functioning, self-medication, and parentification-pseudomaturity. Structural models revealed that child maltreatment predicted poor parenting practices among mothers. Parent alcohol- and drug-related problems had an indirect detrimental influence on mothers' parenting and practices through self-drug problems. Among fathers, emotional neglect experienced as a child predicted lack of parental warmth more parental neglect, and sexual abuse experienced as a child predicted a rejecting style of parenting.
Analyzing HIV/AIDS and Alcohol and Other Drug Use as a Social Problem
PATTERSON, DAVID A.; Wolf (Adelv unegv Waya), Silver
2012-01-01
Most prevention and intervention activities directed toward HIV/AIDS and alcohol and other drug use separately as well as the combining of the two (e.g., those who are both HIV/AIDS and using alcohol and other drugs) comes in the form of specific, individualized therapies without consideration of social influences that may have a greater impact on this population. Approaching this social problem from the narrowed view of individualized, mi-cro solutions disregards the larger social conditions that affect or perhaps even are at the root of the problem. This paper analyzes the social problem of HIV/AIDS and alcohol and other drug abuse using three sociological perspectives—social construction theory, ethnomethodology, and conflict theory—informing the reader of the broader influences accompanying this problem.

Energy drinks are highly caffeinated beverages that are increasingly consumed by young adults. Prior research has established associations between energy drink use and heavier drinking and alcohol-related problems among college students. This study investigated the extent to which energy drink use might pose additional risk for alcohol dependence over and above that from known risk factors. Data were collected via personal interview from 1,097 fourth-year college students sampled from 1 large public university as part of an ongoing longitudinal study. Alcohol dependence was assessed according to DSM-IV criteria. After adjustment for the sampling design, 51.3%(wt) of students were classified as "low-frequency" energy drink users (1 to 51 days in the past year) and 10.1%(wt) as "high-frequency" users (≥52 days). Typical caffeine consumption varied widely depending on the brand consumed. Compared to the low-frequency group, high-frequency users drank alcohol more frequently (141.6 vs. 103.1 days) and in higher quantities (6.15 vs. 4.64 drinks/typical drinking day). High-frequency users were at significantly greater risk for alcohol dependence relative to both nonusers (AOR = 2.40, 95% CI = 1.27 to 4.56, p = 0.007) and low-frequency users (AOR = 1.86, 95% CI = 1.10, 3.14, p = 0.020), even after holding constant demographics, typical alcohol consumption, fraternity/sorority involvement, depressive symptoms, parental history of alcohol/drug problems, and childhood conduct problems. Low-frequency energy drink users did not differ from nonusers on their risk for alcohol dependence. Weekly or daily energy drink consumption is strongly associated with alcohol dependence. Further research is warranted to understand the possible mechanisms underlying this association. College students who frequently consume energy drinks represent an important target population for alcohol prevention. Copyright © 2010 by the Research Society on Alcoholism.
Prevalence of skin problems and leg ulceration in a sample of young injecting drug users.
Coull, Alison F; Atherton, Iain; Taylor, Avril; Watterson, Andrew E

Drug users suffer harm from the injecting process, and clinical services are reporting increasing numbers presenting with skin-related problems such as abscesses and leg ulcers. Skin breakdown can lead to long-term health problems and increased service costs and is often the first indication of serious systemic ill health. The extent of skin problems in injecting drug users has not previously been quantified empirically, and there is a dearth of robust topical literature. Where skin problems have been reported, this is often without clear definition and generic terms such as 'soft tissue infection' are used which lack specificity. The aim of this study was to identify the range and extent of skin problems including leg ulceration in a sample of injecting drug users. Definitions of skin problems were developed and applied to descriptions from drug users to improve rigour. Data were collected in needle exchanges and methadone clinics across Glasgow, Scotland, from both current and former drug injectors using face-to-face interviews. Two hundred participants were recruited, of which 74% (n = 148) were males and 26% (n = 52) were females. The age range was 21-44 years (mean 35 years). Just under two thirds (64%, n = 127) were currently injecting or had injected within the last 6 months, and 36% (n = 73) had previously injected and had not injected for more than 6 months.Sixty per cent (n = 120) of the sample had experienced a skin problem, and the majority reported more than one problem. Most common were abscesses, lumps, track marks and leg ulcers. Fifteen per cent (n = 30) of all participants reported having had a leg ulcer. This is an original empirical study which demonstrated unique findings of a high prevalence of skin disease (60%) and surprisingly high rates of leg ulceration (15%). Skin disease in injecting drug users is clearly widespread. Leg ulceration in particular is a chronic recurring condition that is costly to treat and has long-term implications for drug users and services caring for current or former injectors long after illicit drug use has ceased.

Pharmacists, the most accessible of health care professionals, are well positioned to help prevent and treat substance use disorders and should prepare themselves to perform these functions. New research improves our knowledge about the pharmacological and behavioral risks of drug abuse, supports the clinical impression that drug dependence is associated with long-lasting neurochemical changes, and demonstrates effective pharmacological treatments for certain kinds of drug dependencies. The profession is evolving. Pharmacists are engaging in new practice behaviors such as helping patients manage their disease states. Collaborative practice agreements and new federal policies set the stage for pharmacists to assist in the clinical management of opioid and other drug dependencies. Pharmacists need to be well informed about issues related to addiction and prepared not only to screen, assess, and refer individual cases and to collaborate with physicians caring for chemically dependent patients, but also to be agents of change in their communities in the fight against drug abuse. At the end of this article the pharmacist will be better able to: 1. Explain the disease concept of chemical dependence 2. Gather the information necessary to conduct a screen for chemical dependence 3. Inform patients about the treatment options for chemical dependence 4. Locate resources needed to answer questions about the effects of common drugs of abuse (alcohol, marijuana, narcotics, "ecstasy", and cocaine) 5. Develop a list of local resources for drug abuse treatment 6. Counsel parents who are concerned about drug use by their children 7. Counsel individuals who are concerned about drug use by a loved one. 8. Counsel individuals who are concerned about their own drug use PMID:15169544

The aims of this study were to examine evidence for the concurrent validity of two self-report measures and two staff-report measures measuring alcohol and drug problems in seriously mentally ill people and to examine if psychotic patients under-report their alcohol and drug problems in an early intervention clinic. This is a cross-sectional study of 48 patients (26 inpatients and 22 outpatients) from an early intervention clinic for psychosis. To examine the sensitivity and specificity, we compared both the staff-report measures Clinical Alcohol Use Scale (AUS) and Clinical Drug Use Scale (DUS) and the self-report measures Short Michigan Alcohol Screening Test (SMAST-13) and Drug Abuse Screening Test (DAST-20), with the current ICD-10 diagnostic criteria as the gold-standard for alcohol and drug problems. To examine whether the patients under-report their alcohol and drug problems, we also compared the self-report measures SMAST-13 and DAST-20 with the staff-report measures AUS and DUS and ICD-10 consensus substance abuse diagnoses. The results show that the concurrent validity compared with ICD-10 diagnoses was moderate for both the staff-report measures AUS and DUS and for the self-report measures SMAST-13 and DAST-20. Three out of seven patients under-report alcohol problems and one patient out of seven under-report drug use problems according to consensus ICD-10 substance abuse diagnoses. We conclude that the SMAST-13 and DAST-20 in combination with the AUS and DUS, which are easy and quick to perform, are helpful in establishing a common understanding of the patient's alcohol and drug problems in an early intervention clinic.

Drug addiction is a chronic, relapsing health problem that is associated with the degree to which individuals choose small, immediate monetary outcomes over larger, delayed outcomes. This study was a secondary analysis exploring the relation between financial choices and drug use in opioid-dependent adults in a therapeutic workplace intervention. Sixty-seven participants were randomly assigned to a condition in which access to paid job training was contingent upon naltrexone adherence (N = 35) or independent of naltrexone adherence (N = 32). Participants could earn approximately $10 per hour for 4 hours every weekday and could exchange earnings for gift cards or bill payments each weekday. Urine was collected and tested for opiates and cocaine thrice weekly. Participants’ earning, spending, and drug use were not related to measures of delay discounting obtained prior to the intervention. When financial choices were categorized based on drug use during the intervention, however, those with less frequent drug use or frequent use of one drug spent a smaller proportion of their daily earnings and maintained a higher daily balance than those who frequently tested positive for both drugs (i.e., opiates and cocaine). Several patterns described the relation between cumulative earning and spending including no saving, periods of saving, and sustained saving. One destructive effect of drug use may be that it creates a perpetual zero-balance situation in the lives of users, which in turn prevents them from gaining materials that could help to break the cycle of addiction.

Few studies have attempted to characterize how co-occurring risk factors for substance use disorders intersect. A recent study examined this question regarding cigarette smoking and demonstrated that co-occurring risk factors generally act independently. The present study examines whether that same pattern of independent intersection of risk factors extends to illicit drug abuse/dependence using a U.S. nationally representative sample (National Survey on Drug Use and Health, 2011–2013). Logistic regression and classification and regression tree (CART) modeling were used to examine risk of past-year drug abuse/dependence associated with a well-established set of risk factors for substance use (age, gender, race/ethnicity, education, poverty, smoking status, alcohol abuse/dependence, mental illness). Each of these risk factors was associated with significant increases in the odds of drug abuse/dependence in univariate logistic regressions. Each remained significant in a multivariate model examining all eight risk factors simultaneously. CART modeling of these 8 risk factors identified subpopulation risk profiles wherein drug abuse/dependence prevalence varied from < 1% to > 80% corresponding to differing combinations of risk factors present. Alcohol abuse/dependence and cigarette smoking had the strongest associations with drug abuse/dependence risk. These results demonstrate that co-occurring risk factors for illicit drug/abuse dependence generally intersect in the same independent manner as risk factors for cigarette smoking, underscoring further fundamental commonalities across these different types of substance use disorders. These results also underscore the fundamental importance of differences in the presence of co-occurring risk factors when considering the often strikingly different prevalence rates of illicit drug abuse/dependence in U.S. population subgroups.

Is Ayahuasca an Option for the Treatment of Crack Cocaine Dependence?
Cruz, Joselaine Ida; Nappo, Solange Aparecida
2018-04-02
The low efficacy of crack cocaine addiction treatment available in Brazil has led Brazilian users to find alternatives to reduce drug consumption or even to reach abstinence. One of them is the use of entheogenic substances, like ayahuasca, an infusion obtained from two native plant species from the Amazon. The present report aimed to understand how crack cocaine users recover from drug addiction by consuming ayahuasca tea in a religious context. This is a qualitative study with a purposeful sample of 40 crack cocaine users, based on in-depth, semi-structured interviews. Participants reported that ayahuasca allowed them to access a consciousness dimension which enabled them to solve problems and traumas and reduce crack cocaine consumption. The religious ceremony increased the user's spirituality and the reception from the community gave them a sense of self-esteem, strengthening them in an emotional and social way. That positive experience has been incorporated into the daily routine of most participants. Findings indicate that ayahuasca, in a religious context, may have therapeutic value for crack cocaine dependence treatment.

Information on medication use and drug-related problems is important in the preparation of clinical medication reviews. Critical information can only be provided by patients themselves, but interviewing patients is time-consuming. Alternatively, patient information could be obtained with a questionnaire. In this study the agreement between patient information on medication use and drug-related problems in older patients obtained with a questionnaire was compared with information obtained during an interview. General practice in The Netherlands. A questionnaire was developed to obtain information on actual medication use and drug-related problems. Two patient groups ≥65 years were selected based on general practitioner electronic medical records in nine practices; I. polypharmacy and II. ≥1 predefined general geriatric problems. Eligible patients were asked to complete the questionnaire and were interviewed afterwards. Agreement on information on medication use and drug-related problems collected with the questionnaire and interview was calculated. Ninety-seven patients participated. Of all medications used, 87.6 % (95 % CI 84.7-90.5) was reported identically in the questionnaire and interview. Agreement for the complete medication list was found for 45.4 % (95 % CI 35.8-55.3) of the patients. On drug-related problem level, agreement between questionnaire and interview was 75 %. Agreement tended to be lower in vulnerable patients characterized by ≥4 chronic diseases, ≥10 medications used and low health literacy. Information from a questionnaire showed reasonable agreement compared with interviewing. The patients reported more medications and drug-related problems in the interview than the questionnaire. Taking the limitations into account, a questionnaire seems a suitable tool for medication reviews that may replace an interview for most patients.

Microbial pathogens represent an increasing threat to human health. Although many infections can be successfully treated and cleared, drug resistance is a widespread problem. The existence of subpopulations of 'tolerant' cells (where a fraction of the population is able to grow above the population resistance level) may increase the rate of treatment failure; yet, existing methods to measure subpopulation effects are cumbersome. Here we describe diskImageR, a computational pipeline that analyses photographs of disk diffusion assays to determine the degree of drug susceptibility [the radius of inhibition, (RAD)], and two aspects of subpopulation growth [the fraction of growth (FoG) within the zone of inhibition, (ZOI), and the rate of change in growth from no drug to inhibitory drug concentrations, (SLOPE)]. diskImageR was used to examine the response of the human fungal pathogen Candida albicans to the antifungal drug fluconazole across different strain backgrounds and growth conditions. Disk diffusion assays performed under Clinical and Laboratory Standards Institute (CLSI) conditions led to more susceptibility and less tolerance than assays performed using rich medium conditions. We also used diskImageR to quantify the effects of three drugs in combination with fluconazole, finding that all three combinations affected tolerance, with the effect of one drug (doxycycline) being very strain dependent. The three drugs had different effects on susceptibility, with doxycycline generally having no effect, chloroquine generally increasing susceptibility and pyrvinium pamoate generally reducing susceptibility. The ability to simultaneously quantitate different aspects of microbial drug responses will facilitate the study of mechanisms of subpopulation responses in the presence of antimicrobial drugs.
Silica-based mesoporous nanoparticles for controlled drug delivery

Drug molecules with lack of specificity and solubility lead patients to take high doses of the drug to achieve sufficient therapeutic effects. This is a leading cause of adverse drug reactions, particularly for drugs with narrow therapeutic window or cytotoxic chemotherapeutics. To address these problems, there are various functional biocompatible drug carriers available in the market, which can deliver therapeutic agents to the target site in a controlled manner. Among the carriers developed thus far, mesoporous materials emerged as a promising candidate that can deliver a variety of drug molecules in a controllable and sustainable manner. In particular, mesoporous silica nanoparticles are widely used as a delivery reagent because silica possesses favourable chemical properties, thermal stability and biocompatibility. Currently, sol-gel-derived mesoporous silica nanoparticles in soft conditions are of main interest due to simplicity in production and modification and the capacity to maintain function of bioactive agents. The unique mesoporous structure of silica facilitates effective loading of drugs and their subsequent controlled release. The properties of mesopores, including pore size and porosity as well as the surface properties, can be altered depending on additives used to fabricate mesoporous silica nanoparticles. Active surface enables functionalisation to modify surface properties and link therapeutic molecules. The tuneable mesopore structure and modifiable surface of mesoporous silica nanoparticle allow incorporation of various classes of drug molecules and controlled delivery to the target sites. This review aims to present the state of knowledge of currently available drug delivery system and identify properties of an ideal drug carrier for specific application, focusing on mesoporous silica nanoparticles.

Asthma and chronic obstructive pulmonary disease are preventable and treatable chronic airway diseases with high incidence and prevalence. Pharmacists and clinical pharmacy based pharmaceutical care services have positive impact on therapy outcomes. The aim of this study is to describe drug related problems in a cohort of patients with asthma and chronic obstructive pulmonary disease and to assess interventions provided by the pharmacist to address these problems in a community pharmacy. Study population consisted of patients with asthma and chronic obstructive pulmonary disease older than 18 years who visited the study pharmacy during the pre-determined six-month period. The patients whose disease control states were "not fully controlled" were included in our study for further steps. On the first interview, present and potential drug related problems were addressed, interventions were provided. Follow-up interviews were held one month and two months later than the first interview. For the 44 patients with asthma, 59 drug-related problems and 134 causes for these problems were identified. Eighty-four interventions were made to resolve the problems; and 54.2% of the problems were resolved. For the 37 patients with chronic obstructive pulmonary disease, 60 drug-related problems and 128 causes for these problems were identified. Ninety-five interventions were made to resolve the problems; and 63.3% of the problems were resolved. Pharmacists taking part in therapy and management of asthma and chronic obstructive pulmonary disease can help patients be more educated about their disease and medications; and improve disease control and therapy outcomes.

Multiple drug target analysis (MDTA) used in doping control is more efficient than single drug target analysis (SDTA). The number of drugs with the potential for abuse is so extensive that full coverage is not possible with SDTA. To address this problem, a liquid chromatography tandem mass spectrometric method was developed for simultaneous analysis of 302 drugs using a scheduled multiple reaction monitoring (s-MRM) algorithm. With a known retention time of an analyte, the s-MRM algorithm monitors each MRM transition only around its expected retention time. Analytes were recovered from plasma by liquid-liquid extraction. Information-dependent acquisition (IDA) functionality was used to combine s-MRM with enhanced product ion (EPI) scans within the same chromatographic analysis. An EPI spectrum library was also generated for rapid identification of analytes. Analysis time for the 302 drugs was 7 min. Scheduled MRM improved the quality of the chromatograms, signal response, reproducibility, and enhanced signal-to-noise ratio (S/N), resulting in more data points. Reduction in total cycle time from 2.4 s in conventional MRM (c-MRM) to 1 s in s-MRM allowed completion of the EPI scan at the same time. The speed for screening and identification of multiple drugs in equine plasma for doping control analysis was greatly improved by this method.
Psychiatric services in primary care settings: a survey of general practitioners in Thailand
Lotrakul, Manote; Saipanish, Ratana
2006-01-01
Background General Practitioners (GPs) in Thailand play an important role in treating psychiatric disorders since there is a shortage of psychiatrists in the country. Our aim was to examine GP's perception of psychiatric problems, drug treatment and service problems encountered in primary care settings. Methods We distributed 1,193 postal questionnaires inquiring about psychiatric practices and service problems to doctors in primary care settings throughout Thailand. Results Four hundred and thirty-four questionnaires (36.4%) were returned. Sixty-seven of the respondents (15.4%) who had taken further special training in various fields were excluded from the analysis, giving a total of 367 GPs in this study. Fifty-six per cent of respondents were males and they had worked for 4.6 years on average (median = 3 years). 65.6% (SD = 19.3) of the total patients examined had physical problems, 10.7% (SD = 7.9) had psychiatric problems and 23.9% (SD = 16.0) had both problems. The most common psychiatric diagnoses were anxiety disorders (37.5%), alcohol and drugs abuse (28.1%), and depressive disorders (29.2%). Commonly prescribed psychotropic drugs were anxiolytics and antidepressants. The psychotropic drugs most frequently prescribed were diazepam among anti-anxiety drugs, amitriptyline among antidepressant drugs, and haloperidol among antipsychotic drugs. Conclusion Most drugs available through primary care were the same as what existed 3 decades ago. There should be adequate supply of new and appropriate psychotropic drugs in primary care. Case-finding instruments for common mental disorders might be helpful for GPs whose quality of practice was limited by large numbers of patients. However, the service delivery system should be modified in order to maintain successful care for a large number of psychiatric patients. PMID:16867187
Prenatal Drug Exposure and Adolescent Cortisol Reactivity: Association with Behavioral Concerns.

To examine stress reactivity in a sample of adolescents with prenatal drug exposure (PDE) by examining the consequences of PDE on stress-related adrenocortical reactivity, behavioral problems, and drug experimentation during adolescence. Participants (76 PDE, 61 non-drug exposed [NE]; 99% African-American; 50% male; mean age = 14.17 yr, SD = 1.17) provided a urine sample, completed a drug use questionnaire, and provided saliva samples (later assayed for cortisol) before and after a mild laboratory stress task. Caregivers completed the Behavior Assessment System for Children, Second Edition (BASC II) and reported their relationship to the adolescent. The NE group was more likely to exhibit task-related cortisol reactivity compared to the PDE group. Overall behavior problems and drug experimentation were comparable across groups with no differences between PDE and NE groups. In unadjusted mediation analyses, cortisol reactivity mediated the association between PDE and BASC II aggression scores (95% bootstrap confidence interval [CI], 0.04-4.28), externalizing problems scores (95% bootstrap CI, 0.03-4.50), and drug experimentation (95% bootstrap CI, 0.001-0.54). The associations remain with the inclusion of gender as a covariate but not when age is included. Findings support and expand current research in cortisol reactivity and PDE by demonstrating that cortisol reactivity attenuates the association between PDE and behavioral problems (aggression) and drug experimentation. If replicated, PDE may have long-lasting effects on stress-sensitive physiological mechanisms associated with behavioral problems (aggression) and drug experimentation in adolescence.

The present study was designed to examine the extent to which (a) family and school functioning and (b) personal and ethnic identity is associated with conduct problems, drug use, and sexual risk taking in a sample of 227 high-risk Hispanic adolescents. Adolescents participated in the study with their primary parents, who were mostly mothers. Adolescents completed measures of family and school functioning, personal and ethnic identity, conduct problems, and drug use. Parents completed measures of family functioning and adolescent conduct problems. Results indicated that school functioning and personal identity confusion were related to alcohol use, illicit drug use, and sexual risk taking indirectly through adolescent reports of conduct problems. Adolescent reports of family functioning were related to alcohol use, illicit drug use, and sexual risk taking through school functioning and conduct problems. Results are discussed in terms of the problem behavior syndrome and in terms of the finding of relative independence of contextual and identity variables vis-à-vis conduct problems, substance use, and sexual risk taking.

Opioid dependence is a complex medical condition affecting neurocognitive and physical functioning. Forced or abrupt opioid withdrawal may cause profound physical and psychological suffering, including nausea, vomiting, diarrhea, extreme agitation and/or anxiety. Opioid dependent individuals are especially vulnerable at the time of arrest or initial detention, when they may, as a result of their chemical dependency, be coerced into providing incriminating testimony, or be driven to engage in risky behavior (such as sharing needles in detention) in order to avoid painful withdrawal symptoms Upon incarceration, many opioid dependent prisoners are forced to undergo abrupt opioid withdrawal (both from legally prescribed agonist therapy such as methadone as well as illicit opioids). Physical and psychological symptoms attendant to withdrawal may impair capacity to make informed legal decisions, and cause prisoners to risk HIV and other bloodborne diseases by sharing injection equipment. Although prisons must provide at least the standard of care to prisoners that is available in the general population, medication-assisted treatment, endorsed by international health and drug agencies as an integral part of HIV prevention and care strategies for opioid dependent drug users, is unavailable to most prisoners. Medication-assisted treatment is a well-studied and validated pharmacological therapy for the medical condition known as opioid dependence. The failure to ensure prisoner access to this medical therapy threatens fundamental human rights protections against cruel, inhuman or degrading treatment and rights to health and to life. It also poses serious ethical problems for health care providers, violating basic principles of beneficence and non-maleficence (i.e., do good/do no harm). Governments must take immediate action to ensure access to opioid substitution to prisoners to ensure fulfillment of ethical and human rights obligations. PMID:18226517

Purpose of review In this study, we reviewed data on drug use among high school students in Iran. Recent findings Published epidemiological studies in international and domestic journals show that drug use/abuse is a serious mental health problem in Iran. There is cultural support for opium in Iran, and also there is cultural tolerance for tobacco smoking, especially as water pipe smoking, in Iranian families. Alcohol, opium, and cannabis are the most frequently used illicit drugs, but there are new emerging problems with anabolic steroids, ecstasy, and stimulant substances, such as crystal methamphetamine. Summary There is serious drug abuse problem among Iranian high school students. It could be due to role-modeling by parents – mainly fathers – and also cultural tolerance of some substances. Early onset of tobacco smoking, with a daily use rate between 4.4% and 12.8% in high school students, is an important risk factor for other drug abuse problems. Use of all types of drugs, except prescription drugs, is more prevalent among boys. Alcohol is the most frequently abused substance, with a lifetime rate of at least 9.9%. Lifetime rates of opiate use – mostly opium – were between 1.2 an 8.6% in different parts of the country. As drug abuse is a frequent problem among Iranian high school students, it is necessary to design and implement drug prevention programs to protect them. Such programs, including life skills training and drug education, have been operating in recent years for Iranian students from kindergarten to the university level. PMID:20308905

Associated with social and individual harm, loss of control and destructive behaviour, addiction is widely considered to be a major social problem. Most models of addiction, including the influential disease model, rely on the volition/compulsion binary, conceptualising addiction as a disorder of compulsion. In order to interrogate this prevailing view, this article draws on qualitative data from interviews with people who describe themselves as having an alcohol or other drug 'addiction', 'dependence' or 'habit'. Applying the concept of 'diffraction' elaborated by science studies scholar Karen Barad, we examine the process of 'addicting', or the various ways in which addiction is constituted, in accounts of daily life with regular alcohol and other drug use. Our analysis suggests not only that personal accounts of addiction exceed the absolute opposition of volition/compulsion but also that the polarising assumptions of existing addicting discourses produce many of the negative effects typically attributed to the 'disease of addiction'.
Conceptualizing ethnicity in alcohol and drug research: Epidemiology meets social theory.
Hunt, Geoffrey; Kolind, Torsten; Antin, Tamar
2018-01-01
Since the 1990s, social scientists have rejected notions of ethnicity as something static and discrete, instead highlighting the context-dependent and fluid nature of multiple identities. In spite of these developments, researchers within the substance use fields continue to assess ethnic group categories in ways that suggest little critical reflection in terms of the validity of the measurements themselves, nor the social, bureaucratic, and political decisions shaping standard measures of ethnicity. This paper highlights these considerations, while also acknowledging the role of socially-delineated ethnic categorizations in documenting health inequities and social injustices. We call on researchers in alcohol and drugs research to critically appraise their use of ethnic categorizations, querying how to best measure ethnicity within their own studies in ways that are justified beyond simplified explanations of social convention and that "do no harm" in terms of perpetuating racism and obscuring the roots causes of social and health problems related to alcohol and drugs.

Interest in submicron-sized drug particles has emerged from both laboratory and industrial perspectives in the last decade. Production of crystals in the nano size scale offers a novel way to particles for drug formulation solving formulation problems of drugs with low solubility in class II of the Biopharmaceutical Classification System. In this work niflumic acid nanoparticles with a size range of 200-800nm were produced by the novel crystallization method, electrospray crystallization. Their properties were compared to those from evaporative and anti-solvent crystallizations, using the same organic solvent, acetone. There is a remarkable difference in the product crystal size depending on the applied methods. The size and morphology were analyzed by scanning electron microscopy and laser diffraction. The structure of the samples was investigated using differential scanning calorimetry, Fourier-transformed infrared spectroscopy and X-ray powder diffraction. The particles produced using electrospray crystallization process were probably changing from amorphous to crystalline state after the procedure. Copyright © 2012 Elsevier B.V. All rights reserved.

Reverse rate dependence is a problematic property of antiarrhythmic drugs that prolong the cardiac action potential (AP). The prolongation caused by reverse rate dependent agents is greater at slow heart rates, resulting in both reduced arrhythmia suppression at fast rates and increased arrhythmia risk at slow rates. The opposite property, forward rate dependence, would theoretically overcome these parallel problems, yet forward rate dependent (FRD) antiarrhythmics remain elusive. Moreover, there is evidence that reverse rate dependence is an intrinsic property of perturbations to the AP. We have addressed the possibility of forward rate dependence by performing a comprehensive analysis of 13 ventricular myocyte models. By simulating populations of myocytes with varying properties and analyzing population results statistically, we simultaneously predicted the rate-dependent effects of changes in multiple model parameters. An average of 40 parameters were tested in each model, and effects on AP duration were assessed at slow (0.2 Hz) and fast (2 Hz) rates. The analysis identified a variety of FRD ionic current perturbations and generated specific predictions regarding their mechanisms. For instance, an increase in L-type calcium current is FRD when this is accompanied by indirect, rate-dependent changes in slow delayed rectifier potassium current. A comparison of predictions across models identified inward rectifier potassium current and the sodium-potassium pump as the two targets most likely to produce FRD AP prolongation. Finally, a statistical analysis of results from the 13 models demonstrated that models displaying minimal rate-dependent changes in AP shape have little capacity for FRD perturbations, whereas models with large shape changes have considerable FRD potential. This can explain differences between species and between ventricular cell types. Overall, this study provides new insights, both specific and general, into the determinants of AP duration rate dependence, and illustrates a strategy for the design of potentially beneficial antiarrhythmic drugs.

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

The present study utilized longitudinal data from a community sample (n = 377; 166 trauma-exposed; 54% males; 73% non-Hispanic Caucasian; 22% Hispanic; 5% other ethnicity) to test whether pretrauma substance use problems increase risk for trauma exposure (high-risk hypothesis) or posttraumatic stress disorder (PTSD) symptoms (susceptibility hypothesis), whether PTSD symptoms increase risk for later alcohol/drug problems (self-medication hypothesis), and whether the association between PTSD symptoms and alcohol/drug problems is attributable to shared risk factors (shared vulnerability hypothesis). Logistic and negative binomial regressions were performed in a path analysis framework. Results provided the strongest support for the self-medication hypothesis, such that PTSD symptoms predicted higher levels of later alcohol and drug problems, over and above the influences of pretrauma family risk factors, pretrauma substance use problems, trauma exposure, and demographic variables. Results partially supported the high-risk hypothesis, such that adolescent substance use problems increased risk for assaultive violence exposure but did not influence overall risk for trauma exposure. There was no support for the susceptibility hypothesis. Finally, there was little support for the shared vulnerability hypothesis. Neither trauma exposure nor preexisting family adversity accounted for the link between PTSD symptoms and later substance use problems. Rather, PTSD symptoms mediated the effect of pretrauma family adversity on later alcohol and drug problems, thereby supporting the self-medication hypothesis. These findings make important contributions to better understanding the directions of influence among traumatic stress, PTSD symptoms, and substance use problems.
Motives for using: a comparison of prescription opioid, marijuana and cocaine dependent individuals.

Identification of the motives for drug use is critical to the development of effective interventions. Furthermore, consideration of the differences in motives for drug use across substance dependent populations may assist in tailoring interventions. To date, few studies have systematically compared motives for substance use across drug classes. The current study examined motives for drug use between non-treatment seeking individuals with current prescription opioid, marijuana, or cocaine dependence. Participants (N=227) completed the Inventory of Drug-Taking Situations (IDTS; Annis, Turner & Sklar,1997), which contains eight subscales assessing motives for drug use. The findings revealed that prescription opioid dependent individuals scored significantly higher than all other groups on the Physical Discomfort, Testing Personal Control and Conflict with Others subscales. Both the prescription opioid and cocaine dependent groups scored significantly higher than the marijuana group on the Urges or a Temptation to Use subscale. In contrast, marijuana dependent individuals scored highest on the Pleasant Emotions and Pleasant Times with Others subscales. The marked differences revealed in motives for drug use could be used in the development and implementation of specific treatment interventions for prescription opioid, marijuana and cocaine dependent individuals.

A substantial body of research has established the effectiveness of brief interventions for problem alcohol use. Following these studies, national dissemination projects of screening, brief intervention (BI), and referral to treatment (SBIRT) for alcohol and drugs have been implemented on a widespread scale in multiple states despite little existing evidence for the impact of BI on drug use for non-treatment seekers. This article describes the design of a study testing the impact of SBIRT on individuals with drug problems, its contributions to the existing literature, and its potential to inform drug policy. The study is a randomized controlled trial of an SBIRT intervention carried out in a primary care setting within a safety net system of care. Approximately 1,000 individuals presenting for scheduled medical care at one of seven designated primary care clinics who endorse problematic drug use when screened are randomized in a 1:1 ratio to BI versus enhanced care as usual (ECAU). Individuals in both groups are reassessed at 3, 6, 9, and 12 months after baseline. Self-reported drug use and other psychosocial measures collected at each data point are supplemented by urine analysis and public health-related data from administrative databases. This study will contribute to the existing literature by providing evidence for the impact of BI on problem drug use based on a broad range of measures including self-reported drug use, urine analysis, admission to drug abuse treatment, and changes in utilization and costs of health care services, arrests, and death with the intent of informing policy and program planning for problem drug use at the local, state, and national levels.

Alcohol dependence constitutes a serious worldwide public health problem. The last few decades have seen many pharmacological studies devoted to the improvement of alcoholism treatment. Although psychosocial treatments (e.g. individual or group therapy) have historically been the mainstay of alcoholism treatment, a successful approach for alcohol dependence consists in associating pharmacologic medications with therapy, as 40-70% of patients following only psychosocial therapy typically resume alcohol use within a year of post-detoxification treatment. Nowadays, two main pharmacological options, naltrexone and acomprosate, both approved by the US Food and Drug Administration, are available and seemingly improve on the results yielded by standard techniques employed in the management of alcoholism. However, insufficient data exist to confirm the superiority of one drug over the other, and research is ongoing to determine what type of alcohol-dependent individual benefits the most from using either medication. Available data on the application of both drugs clearly suggest different practical applications. Thus, a fundamental question remains as to how we can identify which alcoholic patients are likely to benefit from the use of naltrexone, acamprosate or both, and which are not. The aim of the present manuscript is to suggest the use of cognitive event-related potentials as an interesting way to identify subgroups of alcoholic patients displaying specific clinical symptoms and cognitive disturbances. We propose that this may help clinicians improve their treatment of alcoholic patients by focusing therapy on individual cognitive disturbances, and by adapting the pharmaceutical approach to the specific needs of the patient.

The potential of methamphetamine, and high-potency crystal methamphetamine in particular, to precipitate psychotic symptoms and psychotic illness is the subject of much speculation internationally. Established psychotic illness is disabling for individuals and costly to society. The aim of this study was to investigate whether use of crystal methamphetamine was associated with greater prevalence of self-reported psychotic illness, compared to use of other forms of methamphetamine. The sample comprised participants interviewed as part of an annual cross-sectional survey of Australian people who inject drugs. Comparisons were made between groups according to the nature of their methamphetamine use: crystal methamphetamine or other forms of methamphetamine. Self-reported diagnoses of psychotic illness and other mental health problems were compared between groups. Predictors of self-reported psychotic illness were examined using multivariable logistic regression analyses. Self-reported psychotic illness was highly prevalent among users of crystal methamphetamine (12.0%), and significantly more so than among users of other forms of methamphetamine (3.9%) (OR=3.36; CI: 1.03-10.97). Significant predictors of self-reported psychosis in the cohort were: use of crystal methamphetamine; dependent use; lack of education beyond high school; and younger age. Highly increased prevalence of self-reported psychotic illness is associated with use of high-potency crystal methamphetamine in people who inject drugs, particularly where there is dependent use. There is an urgent need to develop effective interventions for dependent crystal methamphetamine use; and a need to monitor for symptoms of psychotic illness in drug-using populations.

Self-reported substance use is commonly used as an outcome measure in treatment research. We evaluated the validity of self-reported drug use in a sample of 334 adults with mental health problems who were residing in supportive housing programs. The primary analysis was the calculation of the positive predictive values (PPVs) of self-report compared to an oral fluid test taken at the same time. A sensitivity analysis compared the positive predictive values of two self-reported drug use histories: biological testing window (ranging between the past 96h to 30days depending on drug type) or the full past 90-day comparison window (maximum length recorded during interview). A multivariable logistic regression was used to predict discordance between self-report and the drug test for users. Self-reported drug use and oral fluid drug tests were compared to determine the positive predictive value for amphetamines/methamphetamines/PCP (47.1% agreement), cocaine (43.8% agreement), and marijuana (69.7% agreement) drug tests. Participants who misreported their drug use were more likely to be older, non-White, have no medical insurance, and not report any alcohol use. In general, amphetamine/methamphetamine/PCP and cocaine use was adequately captured by the biological test, while marijuana use was best captured by a combination of self-report and biological data. Using the full past 90day comparison window resulted in higher concordance with the oral fluid drug test, indicating that self-reported drug use in the past 90days may be a proxy for drug use within the biological testing window. Self-report has some disadvantages when used as the sole measure of drug use in this population. Copyright © 2017 Elsevier Ltd. All rights reserved.

Tuberculosis is a major global health problem. However, anti-tuberculosis drug treatment has many adverse effects, such as drug-caused fever. The aim of this study was to investigate the clinical features and treatments of anti-tuberculosis drugs-induced fever. A total of 78 inpatients and outpatients with pulmonary tuberculosis accompanied by drug fever during the anti-tuberculosis treatment were analysed retrospectively from April 2006 to March 2013. Among the anti-tuberculosis drugs that caused the drug fever, rifampicin was the most common one, followed by para-aminosalicylic and pyrazinamide. The symptoms occurred within 2 months after treatment, mainly in the 1-3 weeks, and the main symptom was high fever with body temperature above 39°C. The accompanying symptoms include rash, chills, headache, stuffy nose, runny nose, nausea, vomiting and joint pain. Routine blood examination found that eosinophilia increased in 15 cases and decreased in another 15. Among 63 patients who underwent liver function tests, there were 10 cases of abnormal function and 4 cases of liver damage. When the drug fever was suspected, the measure of withdrawal was taken first. All the suspected drugs were withdrawn in 59 cases, while gradual withdrawal was conducted in 19 cases. Patients with complications were first treated in accordance with the principles of complications treatment and then were gradually given some drugs after recovery. The patients without complications were gradually given some drugs after the body temperature was back to normal. Drug fever is an allergic reaction, the resolution of which depends on whether it was accompanied by liver damage and/or rash or not. © 2014 John Wiley & Sons Ltd.

Laws on compulsory commitment to care (CCC) in mental health, social and criminal legislation for adult persons with alcohol and/or drug dependence or misuse problems are constructed to address different scenarios related to substance use disorders. This study examines how such CCC laws in European states vary in terms of legal rights, formal orders of decision and criteria for involuntary admission, and assesses whether three legal frameworks (criminal, mental and social law) equally well ensure human and civil rights. Thirty-nine laws, from 38 countries, were analysed. Respondents replied in web-based questionnaires concerning a) legal rights afforded the persons with substance use problems during commitment proceedings, b) sources of formal application, c) instances for decision on admission, and d) whether or not 36 different criteria could function as grounds for decisions on CCC according to the law in question. Analysis of a-c were conducted in bivariate cross-tabulations. The 36 criteria for admission were sorted in criteria groups based on principal component analysis (PCA). To investigate whether legal rights, decision-making authorities or legal criteria may discriminate between types of law on CCC, discriminant analyses (DA) were conducted. There are few differences between the three types of law on CCC concerning legal rights afforded the individual. However, proper safeguards of the rights against unlawful detention seem still to be lacking in some CCC laws, regardless type of law. Courts are the decision-making body in 80 % of the laws, but this varies clearly between law types. Criteria for CCC also differ between types of law, i.e. concerning who should be treated: dependent offenders, persons with substance use problems with acting out or aggressive behaviors, or other vulnerable persons with alcohol or drug problems. The study raises questions concerning whether various European CCC laws in relation to substance use disorder or misuse problems comply with international ratified conventions concerning human and civil rights. This, however, applies to all three types of law, i.e. social, mental health and criminal legislation. The main differences between law types concern legal criteria, reflecting different national priorities on implicit ambitions of CCC - for correction, for prevention, or for support to those in greatest need of care.
Earlier Violent Television Exposure and Later Drug Dependence

This research examined the longitudinal pathways from earlier violent television exposure to later drug dependence. African American and Puerto Rican adolescents were interviewed during three points in time (N = 463). Violent television exposure in late adolescence predicted violent television exposure in young adulthood, which in turn was related to tobacco/marijuana use, nicotine dependence, and later drug dependence. Some policy and clinical implications suggest: a) regulating the times when violent television is broadcast; b) creating developmentally targeted prevention/treatment programs; and c) recognizing that watching violent television may serve as a cue regarding increased susceptibility to nicotine and drug dependence.

With the development of Web 2.0 technology, social media websites have become lucrative but under-explored data sources for extracting adverse drug events (ADEs), which is a serious health problem. Besides ADE, other semantic relation types (e.g., drug indication and beneficial effect) could hold between the drug and adverse event mentions, making ADE relation extraction - distinguishing ADE relationship from other relation types - necessary. However, conducting ADE relation extraction in social media environment is not a trivial task because of the expertise-dependent, time-consuming and costly annotation process, and the feature space's high-dimensionality attributed to intrinsic characteristics of social media data. This study aims to develop a framework for ADE relation extraction using patient-generated content in social media with better performance than that delivered by previous efforts. To achieve the objective, a general semi-supervised ensemble learning framework, SSEL-ADE, was developed. The framework exploited various lexical, semantic, and syntactic features, and integrated ensemble learning and semi-supervised learning. A series of experiments were conducted to verify the effectiveness of the proposed framework. Empirical results demonstrate the effectiveness of each component of SSEL-ADE and reveal that our proposed framework outperforms most of existing ADE relation extraction methods The SSEL-ADE can facilitate enhanced ADE relation extraction performance, thereby providing more reliable support for pharmacovigilance. Moreover, the proposed semi-supervised ensemble methods have the potential of being applied to effectively deal with other social media-based problems. Copyright © 2017 Elsevier B.V.

DSM-IV criteria for illicit drug abuse and dependence are largely based on criteria developed for alcohol use disorders and there is a lack of research evidence on the psychometric properties of these symptoms when applied to illicit drugs. This study utilizes data on abuse/dependence criteria for cannabis, cocaine, stimulants, sedatives, tranquilizers, opiates, hallucinogens and inhalants from the National Epidemiological Survey on Alcohol and Related Conditions (NESARC, n=43 093). Analyses included factor analysis to explore the dimensionality of illicit drug abuse and dependence criteria, calculation of item difficulty and discrimination within an item response framework and a descriptive analysis of 'diagnostic orphans': individuals meeting criteria for 1-2 dependence symptoms but not abuse. Rates of psychiatric disorders were compared across groups. Results favor a uni-dimensional construct for abuse/dependence on each of the eight drug classes. Factor loadings, item difficulty and discrimination were remarkably consistent across drug categories. For each drug category, between 29% and 51% of all individuals meeting criteria for at least one symptom did not receive a formal diagnosis of either abuse or dependence and were therefore classified as 'orphans'. Mean rates of disorder in these individuals suggested that illicit drug use disorders may be more adequately described along a spectrum of severity. While there were remarkable similarities across categories of illicit drugs, consideration of item difficulty suggested that some alterations to DSM regarding the relevant severity of specific abuse and dependence criteria may be warranted.

Drug problems in contemporary China: a profile of Chinese drug users in a metropolitan area.
Huang, Kaicheng; Zhang, Lening; Liu, Jianhong
2011-03-01
Drug problems are reemerging in China since the nation implemented economic reform and an "open door" policy in the early 1980s. This is causing both national and international concern. However, knowledge and understanding of the Chinese drug problem is fairly limited because of the nation's unique social and political history. In response to this shortage of information, our study presents a profile of Chinese drug users. Data were collected from a survey of drug users attending mandatory treatment centres in a large city in 2009. We present a demographic profile of the drug users, describe their patterns of drug use, their access to drugs and their history of drug treatment. Chinese drug users, like those from the U.S., are likely to be unemployed and have a low level of education. However, they are more likely than those in the U.S. to use heroin, Bingdu (methamphetamine) and Maguo (a derivative of methamphetamine), and they pay less for their drugs. This profile of drug users is informative and valuable for drug prevention, intervention, and treatment in the Chinese setting because knowing and understanding the drug population is essential for effective control.

Solid dispersion (SD) technique is a promising strategy to improve the solubility and dissolution of BCS class II drugs. However, only few products are marketed till today based on SD technology due to poor flow properties and stability. The present work was intended to solve these problems by using combination approach, melt dispersion and surface adsorption technologies. The main aim of the present work is to improve the absorption in the stomach (at lower pH) where the absorption window exists for the drug by improving the dissolution, resulting in the enhancement of oral bioavailability of poorly soluble, weakly acidic drug with pH dependant solubility, i.e. valsartan. Melt dispersion granules were prepared in different ratios using different carriers (Gelucire 50/13, PEG 8000 and Pluronic F-68) and lactose as an adsorbent. Similarly, physical mixtures were also prepared at corresponding ratios. The prepared dispersion granules and physical mixtures were characterized by FTIR, DSC and in vitro dissolution studies. DSC studies revealed reduction in the crystallinity with a possibility of presence of amorphous character of drug in the dispersion granules. From dissolution studies, valsartan Gelucire dispersion (GSD4; 1:4 ratio) showed complete drug release in 30 min against the plain drug which showed only 11.31% of drug release in 30 min. Pharmacokinetic studies of optimized formulation in male Wistar rats showed 2.65-fold higher bioavailability and 1.47-fold higher Cmax compared to pure drug. The melt dispersion technology has the potential to improve dissolution and the bioavailability of BCS class II drugs.

This study aimed to compare the drug addiction process between Chinese heroin- and methamphetamine (MA)-dependent users via a modified 4-stage addiction model (experimentation, occasional use, regular use, and compulsive use). A descriptive study was conducted among 683 eligible participants. In the statistical analysis, we selected 340 heroin- and 295 MA-dependent users without illicit drug use prior to onset of heroin or MA use. The addiction process of heroin-dependent users was shorter than that of MA-dependent users, with shorter transitions from the onset of drug-use to the first drug craving (19.5 vs. 50.0 days), regular use (30.0 vs. 60.0 days), and compulsive use (50.0 vs. 85.0 days). However, no significant differences in the addiction process were observed in frequency of drug administration, except that heroin users reported more administrations of the drug (20.0 vs. 15.0) before progressing to the stage of compulsive drug use. A larger proportion of regular heroin users progressed to use illicit drugs recklessly than did MA users. Most heroin and MA users reported psychological dependence as their primary motivation for compulsive drug use, but more heroin users selected uncomfortable symptoms upon ceasing drug use as further reason to continue. Our results suggest that typical heroin and MA users may experience a similar four-stage addiction process, but MA users might undergo a longer addiction process (in days). More research is necessary to further explore factors influencing the drug addiction process.

Physicians can encounter problems in prescribing opioids for some patients with chronic pain such as multiple unsanctioned dose escalations, episodes of lost or stolen prescriptions, and positive urine drug screenings for illicit substances. This study explored the usefulness of questions on abuse history in predicting problems with prescribing opioids for patients at a hospital-based pain management program. One hundred forty-five (145) patients who were taking long- and short-acting opioids for their pain were classified as high or low risk on the basis of their responses to interview questions about 1) substance abuse history in their family, 2) past problems with drug or alcohol abuse, and 3) history of legal problems. The treating physicians completed a questionnaire about problems that they had encountered with their patients. Problem behaviors were verified through chart review. No differences in demographic characteristics were found between those classified as high and low risk. Patients who admitted to a family history of substance abuse, a history of legal problems, and drug or alcohol abuse were prone to more aberrant drug-related behaviors, including a higher incidence of lost or stolen prescriptions and the presence of illicit substances in their urine (P < 0.05). Patients classified as high risk also had a significantly higher frequency of reported mental health problems and motor vehicle accidents. More of these patients smoked cigarettes, tended to need a cigarette within the first hour of the day, took higher doses of opioids, and reported fewer adverse effects from the medications than did those without such a history (P < 0.05). This study demonstrates that questions about abuse history and legal problems can be useful in predicting aberrant drug-related behavior with opioid use in persons with chronic noncancer pain.

The most widespread health problem on college and university campuses in the United States is high-risk alcohol and other drug (AOD) use. Recent reports confirm that the nation's campuses continue to encounter significant consequences as a result of this problem. This "Infofacts/Resources" offers an overview of the problem and highlights effective…
Can psychedelic compounds play a part in drug dependence therapy?

After a 40-year hiatus there is now a revisiting of psychedelic drug therapy throughout psychiatry, with studies examining the drugs psilocybin, ketamine, ibogaine and ayahuasca in the treatment of drug dependence. Limitations to these therapies are both clinical and legal, but the possibility of improving outcomes for patients with substance dependency imposes an obligation to research this area.

Background: Dormitory students encounter multiple social factors which cause pressure, such as new social relationships, fear of the future, and separation from family, which could cause serious problems such as tendency toward drug abuse. This research was conducted with the goal to determine social problem-solving skills, dysfunctional attitudes, and risk of drug abuse among dormitory students of Isfahan University of Medical Sciences, Iran. Materials and Methods: This was a descriptive-analytical, correlational, and cross-sectional research. The research sample consisted of 211 students living in dormitories. The participants were selected using randomized quota sampling method. The data collection tools included the Social Problem-Solving Inventory (SPSI), Dysfunctional Attitude Scale (DAS), and Identifying People at Risk of Addiction Questionnaire. Results: The results indicated an inverse relationship between social problem-solving skills and risk of drug abuse (P = 0.0002), a direct relationship between dysfunctional attitude and risk of drug abuse (P = 0.030), and an inverse relationship between social problem-solving skills and dysfunctional attitude among students (P = 0.0004). Conclusions: Social problem-solving skills have a correlation with dysfunctional attitudes. As a result, teaching these skills and the way to create efficient attitudes should be considered in dormitory students. PMID:28904539

Standing Genetic Variation and the Evolution of Drug Resistance in HIV
Pennings, Pleuni Simone

Drug resistance remains a major problem for the treatment of HIV. Resistance can occur due to mutations that were present before treatment starts or due to mutations that occur during treatment. The relative importance of these two sources is unknown. Resistance can also be transmitted between patients, but this process is not considered in the current study. We study three different situations in which HIV drug resistance may evolve: starting triple-drug therapy, treatment with a single dose of nevirapine and interruption of treatment. For each of these three cases good data are available from literature, which allows us to estimate the probability that resistance evolves from standing genetic variation. Depending on the treatment we find probabilities of the evolution of drug resistance due to standing genetic variation between and . For patients who start triple-drug combination therapy, we find that drug resistance evolves from standing genetic variation in approximately 6% of the patients. We use a population-dynamic and population-genetic model to understand the observations and to estimate important evolutionary parameters under the assumption that treatment failure is caused by the fixation of a single drug resistance mutation. We find that both the effective population size of the virus before treatment, and the fitness of the resistant mutant during treatment, are key-parameters which determine the probability that resistance evolves from standing genetic variation. Importantly, clinical data indicate that both of these parameters can be manipulated by the kind of treatment that is used. PMID:22685388

The best practice contract has given a new objective to the hospital pharmacists for the reimbursement in addition to Diagnosis Related Groups' (DRGs) tariffs. We built our pharmaceutical quality control for the administration traceability follow-up regarding the DRGs and the cost of care, for two reasons: the nominal drugs dispensation in link with the prescription made by pharmacist and the important expenditure of these drugs. Our organization depends on the development level of the informatized drugs circuit and minimizes the risk of financial shortfalls or wrong benefits, possible causes of economic penalties for our hospital. On the basis of this follow-up, we highlighted our activity and identified problems of management and drugs circuit organization. The quality of the administration traceability impacts directly on the quality of the medical records and the reimbursements of the expensive drugs. A better knowledge of prescription software is also required for a better quality and security of the medical data used in the medical informatic systems. The drugs management and the personal treatment in and between the care units need to be improved too. We have to continue and improve our organization with the future financial model for ATU drugs and the FIDES project. The health personnel awareness and the development of best informatic tools are also required. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

Drug use remains an important public health concern in the United States, and understanding drug use among young adolescents is vital towards improving the health of the population. This study applied the Problem Behavior Theory (PBT) to lifetime drug use among a cross-sectional sample of Boy Scouts (N = 770). The PBT provides a conceptual framework for identifying risk and protective factors for adolescent problem behaviors, including drug use. Scouts reported their drug use and socio-demographics, and were assessed on several risk and protective factors. For analyses, sociodemographic and risk and protective factors were selected according to the framework provided by PBT, and use of each drug was regressed logistically on these selected factors. Final logistic models were assessed for goodness of fit and discriminatory power. The PBT demonstrated discriminatory power for all drugs (Tjur's R 2 values ≥.29), but fell sharply for illicit drug use (Tjur's R 2 =.20). There were no consistent correlates of drug use. Conclusions/Importance: The PBT had less explanatory power for illicit drug use compared to tobacco, alcohol, and marijuana, which suggests different risk and protective factors were associated with illicit drug use.
