Gambling disorder-related illegal acts: Regression model of associated factors.

Background and aims Gambling disorder-related illegal acts (GDRIA) are often crucial events for gamblers and/or their entourage. This study was designed to determine the predictive factors of GDRIA. Methods Participants were 372 gamblers reporting at least three DSM-IV-TR (American Psychiatric Association, 2000) criteria. They were assessed on the basis of sociodemographic characteristics, gambling-related characteristics, their personality profile, and psychiatric comorbidities. A multiple logistic regression was performed to identify the relevant predictors of GDRIA and their relative contribution to the prediction of the presence of GDRIA. Results Multivariate analysis revealed a higher South Oaks Gambling Scale score, comorbid addictive disorders, and a lower level of income as GDRIA predictors. Discussion and conclusion An original finding of this study was that the comorbid addictive disorder effect might be mediated by a disinhibiting effect of stimulant substances on GDRIA. Further studies are necessary to replicate these results, especially in a longitudinal design, and to explore specific therapeutic interventions.

Towards a Validation of the Three Pathways Model of Pathological Gambling.

With the aim of validating the three pathways hypothesis of pathological gambling (Blaszczynski and Nower in Addiction 97:487-499, 2002) 372 pathological gamblers meeting DSM IV (2000) criteria were assessed via a structured clinical interview as well as being subjected to personality tests and evaluation of their gambling practices. Our results show that it is possible to identify three subgroups corresponding to the three pathways: behaviourally conditioned problem gamblers, emotionally vulnerable problem gamblers and antisocial impulsivist problem gamblers. Our results particularly demonstrate that impulsivist gamblers preferentially choose semi-skilful gambling (horse racing and sports gambling) whereas emotionally vulnerable gamblers are significantly more attracted to games of chance (one-armed bandits, scratch cards, etc.) This led us to propose a functional presentation of the three pathways model which differs somewhat from the Blaszczynski and Nower presentation.

[Prevalence of alcoholism in primary care in the governorate of Sousse]. / Prevalence de l'alcoholisme en première ligne dans le gouvernorat de Sousse.

BACKGROUND: The prevalence related to alcohol use disorders in adults is 1.7%. It varies around the world. In Tunisia, as in most Arab and Muslim countries, alcohol consumption is still a taboo and little studied. AIMS: To estimate the prevalence of alcohol abuse and dependence Band to assess associated socio-demographic factors in primary care patients in Sousse governorate. METHOD: It's a descriptive study carried out between June and November 2006. The sample included 30 primary care units in Sousse governorate, chosen by a stratified random method. We used the Composite International Diagnostic Interview (CIDI 2.1) translated and validated in Tunisian dialect. RESULTS: Our sample included 2577 participants. The lifetime prevalence of alcohol abuse and during the last 12 months were 2.8% and 1%. Those of alcohol dependence were respectively 0.7% and 0.3%. Only one case of alcohol abuse was found among women and no cases of dependence have been noticed. For men's, the prevalence of alcohol abuse at the lifetime and during the last 12 months were 12.8 % and 4.5 %. For men's alcohol dependence, prevalence rates were 3% and 1.6 %. Associated factors with abuse or alcohol dependence were studied in men's sample (n=560). Alcohol abuse was more common after multivariate logistic regression in the age group betwen18 and 34 years and in those with a diploma. Alcohol dependence was associated with only high level of education. CONCLUSION: Our study provides further evidence that alcohol abuse and dependence in primary care remain low compared to other international studies and highlights the role of primary care physicians in the screening of these health problems especially among men.

A Gamblers Clustering Based on Their Favorite Gambling Activity.

The objective of this study was to identify profiles of gamblers to explain the choice of preferred gambling activity among both problem and non-problem gamblers. 628 non-problem and problem gamblers were assessed with a structured interview including "healthy" (sociodemographic characteristics, gambling habits and personality profile assessed with the Temperament and Character Inventory-125) and "pathological" [diagnosis of pathological gambling, gambling-related cognitions (GRCs) and psychiatric comorbidity] variables. We performed a two-step cluster analysis based solely on "healthy" variables to identify gamblers' profiles which typically reflect the choice of preferred gambling activity. The obtained classes were then described using both "healthy" and "pathological" variables, by comparing each class to the rest of the sample. Clusters were generated. Class 1 (Electronic Gaming Machines gamblers) showed high cooperativeness, a lower level of GRC about strategy and more depressive disorders. Class 2 (games with deferred results gamblers) were high novelty seekers and showed a higher level of GRC about strategy and more addictive disorders. Class 3 (roulette gamblers) were more often high rollers and showed a higher level of GRC about strategy and more manic or hypomanic episodes and more obsessive-compulsive disorders. Class 4 (instant lottery gamblers) showed a lower tendency to suicide attempts. Class 5 (scratch cards gamblers) were high harm avoiders and showed a lower overall level of GRC and more panic attacks and eating disorders. The preference for one particular gambling activity may concern different profiles of gamblers. This study highlights the importance of considering the pair gambler-game rather than one or the other separately, and may provide support for future research on gambling and preventive actions directed toward a particular game.

Study protocol: the JEU cohort study--transversal multiaxial evaluation and 5-year follow-up of a cohort of French gamblers.

BACKGROUND: There is abundant literature on how to distinguish problem gambling (PG) from social gambling, but there are very few studies of the long-term evolution of gambling practice. As a consequence, the correlates of key state changes in the gambling trajectory are still unknown. The objective of the JEU cohort study is to identify the determinants of key state changes in the gambling practice, such as the emergence of a gambling problem, natural recovery from a gambling problem, resolution of a gambling problem with intermediate care intervention, relapses or care recourse. METHODS/DESIGN: The present study was designed to overcome the limitations of previous cohort study on PG. Indeed, this longitudinal case-control cohort is the first which plans to recruit enough participants from different initial gambling severity levels to observe these rare changes. In particular, we plan to recruit three groups of gamblers: non-problem gamblers, problem gamblers without treatment and problem gamblers seeking treatment.Recruitment takes place in various gambling places, through the press and in care centers. Cohort participants are gamblers of both sexes who reported gambling on at least one occasion in the previous year and who were aged between 18 and 65. They were assessed through a structured clinical interview and self-assessment questionnaires at baseline and then once a year for five years. Data collection comprises sociodemographic characteristics, gambling habits (including gambling trajectory), the PG section of the DSM-IV, the South Oaks Gambling Screen, the Gambling Attitudes and Beliefs Survey - 23, the Mini International Neuropsychiatric Interview, the Wender-Utah Rating Scale-Child, the Adult ADHD Self-report Scale, somatic comorbidities (especially current treatment and Parkinson disease) and the Temperament and Character Inventory - 125. DISCUSSION: The JEU cohort study is the first study which proposes to identify the predictive factors of key state changes in gambling practice. This is the first case-control cohort on gambling which mixes non-problem gamblers, problem gamblers without treatment and problem gamblers seeking treatment in almost equal proportions. This work may help providing a fresh perspective on the etiology of pathological gambling, which may provide support for future research, care and preventive actions.

Is baclofen a revolutionary medication in alcohol addiction management? Review and recent updates.

Baclofen, a γ-aminobutyric acid (GABA)-B receptor agonist, represents a promising drug in alcohol addiction management. Animal models have shown its action at various stages of the process of alcohol addiction. Moreover, initial open and randomized controlled trials have shown the efficacy of 30 mg/day baclofen on alcohol craving, intake, and relapse prevention. It may also decrease alcohol withdrawal symptoms. However, these initial studies were conducted by the same Italian team; 2 American studies, using a different methodology, did not confirm these effects. Following recent reports by an alcohol-dependent French physician who treated himself with high doses (120-270 mg/day), claiming prolonged suppression of alcohol craving and absence of dependence symptoms, baclofen has since received wide media exposure in France where it has been called "the treatment for alcoholism." An open-label French study supports these findings. In addition, baclofen seems to be particularly interesting because of its safety and tolerance, even in patients with cirrhosis. Thus, baclofen should benefit from further studies of its biobehavioral mechanisms, dose-response effect, and indications in various alcoholic patient profiles.

A step toward an objective quantification of subtle neurological signs in schizophrenia.

Numerous reports have emphasized the value of neurological soft signs (NSS) as endophenotypic markers in schizophrenia. NSS also appear as useful prognostic predictors for functional outcome, response and tolerance to antipsychotics. Although several standardized scales have been proposed and offer fair inter-rater reliability, they still rely on the experience and accuracy of the investigators. This study was designed to assess NSS objectively. We evaluated 27 patients who met the Diagnostic and Statistical Manual, fourth edition (DSM-IV) criteria for schizophrenia and 15 healthy controls using a standardized examination encompassing a 23-item NSS scale as well as an assessment of parkinsonism and dyskinesia. Movements were then recorded using inertia sensors while the patients were performing a selection of motor items from the aforementioned scale (balance tasks, rapid alternative movements, rigidity). To our knowledge, this study is the first to provide an objective assessment of specific NSS in schizophrenia using inertial sensors. The results objectively demonstrate impairments in patients with schizophrenia when balance relies on proprioceptive information, with specific differences in groups of patients based on their NSS scores. Inertia sensors are promising, inexpensive and 'easy-to-use' tools that could improve the assessment of motor and sensory impairments in patients with schizophrenia in daily clinical practice, especially when the dysfunction is subtle.

Association of inflammation genes with alcohol dependence/abuse: a systematic review and a meta-analysis.

The aim of the present work was to systematically review all association studies of inflammation genes with alcohol dependence/alcohol abuse (AD/AA) and to perform a meta-analysis. Odds ratios (ORs) were estimated by contrasting the ratio of counts of the 'high-risk' versus 'low-risk' alleles in AD/AA cases versus controls. Data reported in at least three published studies were available for four genetic polymorphisms [TNF-α-238 (rs361525, G/A); TNF-α-308 (rs1800629, G/A); IL-1RA (VNTR [86 bp]n); IL-10-592 (rs1800896, C/A)]. In total, nine meta-analyses were performed. Of these, only the TNF-α-238 polymorphism showed a significant association with AD/AA (OR=1.36, 95% CI: 1.05-1.76). This risk remained significant and increased slightly when we considered only patients with advanced alcohol-related liver disease (AALD) (OR=1.5, 95% CI: 1.13-1.98) but not when we considered only patients without AALD (OR=1.08, 95% CI: 0.5-2.35). Sensitivity analysis showed that this genetic association is derived from the AALD phenotype rather than from AD. Our approach is limited by our phenotype definition; some studies included chronic heavy drinkers (minimal daily consumption of 80 g for a minimal duration of 10 years) but without a standardized psychiatric assessment.
