Their temporality could evoke a role of dopamine, especially since the underlying mechanism of these depressive symptoms is not well understood. We hypothesized that variation in the dopaminergic activity profile, modeled from clinical markers, could be implicated in the development of depressive symptoms during cocaine withdrawal. Methods: We compared patients reporting depressive symptoms (RDS+) or not (RDS–) during cocaine withdrawal. We evaluated dopaminergic activity through indirect clinical markers based on the known dopaminergic behaviors. A combined criterion was constructed for hyper and hypo dopaminergic models according to the O'Brien method and illustrated by the Hedges' effect-size and forest-plot graph. A multidimensional factorial analysis was carried out to determine which parameters discriminate RDS...

But the main difficulty is its diagnosis. What resources are available in French, which seem to help therapists in this process? We can distinguish the non-dimensional approach, the use of self-administered questionnaires or interviewer-administrated questionnaires. In this paper, for reasons of editing constraints, we are interested only in non-dimensional approach and direct assessment measures by selfassessment, analyzing the strengths and limitations of each and taking into account scientific studies that have been devoted to them and their clinical relevance. We first considered various aspects of non-dimensional approach through suicidal risk factors research, suicidal emergency and suicidal potential concepts, Shea approach, the model of Mann and some recommended evaluations. This type of approach has a number of advantages, but also limitations.

In alcohol research, several studies have shown that computerized training on attentional bias decreases alcohol consumption bias among students. However, these highly controlled experimental situations, do not allow for direct large-scale dissemination. Our objective is to evaluate an attentional bias remediation program using a gamified smartphone training procedure.MethodsFifty students from Clermont-Ferrand University were invited to participate in the study. After a cognitive assessment in the laboratory, the smartphone application was installed on each Student’s smartphone. Participants were randomly assigned to either the alcohol attentional training group or the control group Each student had to complete the 2-min program at least once a day for 15 days. After 15 days, a new cognitive assessment of attention bias was conducted in the lab...

The heterogeneity of practice highlights the need to seek the advice of experts in order to establish a national consensus. This Delphi survey aimed to reach a national consensus on the use of ketamine in chronic pain in Pain clinics.

The therapeutic potential of repetitive transcranial magnetic stimulation (rTMS) on it, by targeting craving in particular, has been explored with heterogenous results. This meta-analysis uses updated evidence to assess overall rTMS efficacy on craving, differential effects between addiction types clustered into three groups (depressant (alcohol, cannabis, opiate), stimulant (nicotine, cocaine, methamphetamine), and behavioral addiction (gambling, eating disorder)), and stimulation settings. Studies on substance use, gambling, and eating disorders are included, with unrestricted stimulation settings, by searching the PubMed, Embase, PsycINFO, and Cochrane databases up to 30 April 2020. A total of 34 eligible studies (42 units of analysis) were identified. Because of highly significant heterogeneity in primary results, a sensitivity analysis was performed on a remaining sample of 26 studies (30 units of analysis...

Problematic eating behaviors are likely to be impacted by the pandemic through multiple pathways. This study examined the relationships between stress related to lockdown measures and binge eating and dietary restriction in a population of French students during the first week of confinement.MethodsA sample of undergraduate students (N = 5,738) completed an online questionnaire 7 days after lockdown measures were introduced. The survey comprised variables related to lockdown measures and the COVID-19-pandemic, mood, stress, body image, binge eating and dietary restriction during the past 7 days, as well as intent to binge eat and restrict in the following 15 days.ResultsStress related to the lockdown was associated with greater likelihood of binge eating and dietary restriction over the past week and intentions to binge eat and restrict over the next 15 days. Great...

Methods: Schizophrenic patients (N = 120) completed the Beliefs about Medicines Questionnaire and measures of medication adherence, and clinical outcomes. Comparison between four attitudinal groups and logistic regressions were performed. Results: High level of adherence varied significantly between attitudinal groups (Accepting, 70%; Indifferent, 63%; Ambivalent, 50%; Sceptical, 14%; p b 0.001). Poor insight and psychic side effects were the most significant predictors of negative beliefs. Conclusion: The attitudinal groups approach could facilitate the identification of patients with non-adherence and determine individual targets of interventions to improve negative beliefs.

This paper focuses on the effectiveness of a social networking site (SNS) alcohol prevention program targeted toward young people. We hypothesized that the program would diminish the relation made by participants between alcohol and festive moments, and would result in a reduction of their declared consumption of alcohol at festive moments during the program. We also explored the interaction with the prevention program that was the most efficient. The prevention program took the form of 3 lotteries over 2 years. The participants periodically received prevention messages, particularly on alcohol and festive moments (eg, videos on Facebook and short message service [SMS] text messages on their mobile phones). For the 3 periods, the participants had to answer questions exploring the level of their belief that alcohol consumption and festive m...

However, no comparisons of the prevalence of addictive behaviors in patients with Parkinson's disease and the general population have been published. The objective of this study was to compare the prevalence and characteristics of addictions (gambling, hypersexuality, tobacco, and alcohol) in patients with Parkinson's disease and in a matched, paired sample from the general population. After matching for age, sex, and complete field questionnaires on addictions, we had 115 data sets. No difference was observed between Parkinson's disease and control populations concerning pathological gambling (0.87% vs 0.87%, P = .99), tobacco addiction (1.7% vs 1.7%, P = .99), and alcohol dependence (2.6% vs 3.5%, P = .71). The Parkinson's disease group showed 2 cases of sexual addiction (1.7% vs 0, P = .15). Our results indicate that patients with Parkinson'...
