Creating a psychosocial intervention combining growth mindset and implementation intentions (GMII) to reduce alcohol consumption: A mixed method approach.

This work aimed at creating a psychosocial intervention based on growth mindset theory and implementation intention strategies, in order to reduce alcohol consumption among users in the general population, and the clinical population of individuals with alcohol use disorder. A mixed method approach was used, combining qualitative and quantitative research methods among both populations. Four focus groups were first conducted to extract arguments in favor of a malleable view of alcohol consumption (study 1A), situations that trigger the desire to drink alcohol, as well as strategies used by people to counteract this need (study 1B).

[Opioids substitution therapy: A respect for the dignity of the human person].

The Opioid substitution treatment (OST) has been highly argumentative in ways that raise important ethical issues. The stigma in treating opioid addiction continues to be a major barrier to effective management plan. It prevents individuals from seeking treatment and is associated with poor mental and physical health.

[Problematic gambling and criminal responsibility].

Objectives: In total, 14% to 30 % of individuals with gambling disorder engage in illegal acts to finance such behavior. This clinical situation could be explained by higher gambling severity, associated substance use disorder, antisocial personality disorder and economic factors (debts, financial problems). The present work focuses, more broadly, on criminal responsibility of problematic gamblers.

[How to manage adult attention deficit hyperactivity disorder in patients with substance use disorders?].

How to manage adult attention deficit hyperactivity disorder in patients with substance use disorders? Adult attention deficit hyperactivity disorder (ADHD) frequently occurs with anxiety disorders, mood disorders and above all addictive comorbidities. Its evaluation must be systematic during an addictology consultation. ADHD is a neurodevelopmental disorder characterized by a complex clinical picture combining cognitive, affective and behavioral dimensions that frequently underlies addictive disorder.

Toward a better understanding of the influence of repetitive negative thinking in alcohol use disorder: An examination of moderation effect of metacognitive beliefs and gender.

Repetitive negative thinking (RNT), the most studied forms of which are depressive ruminations and anxious worry, is a unique transdiagnostic process responsible for the development and maintenance of many mental disorders. Over the past decade, studies have shown that RNT could be involved in the development and maintenance of alcohol use disorder (AUD). However, to date, little is known about the factors that can influence this relationship, even though some theoretical and empirical arguments suggest that variables such as gender or metacognitive beliefs may determine the role of RNT in the onset of symptoms.

[Clinical aspects and therapeutic positioning in addictology].

The concept of addiction emerged subsequent to the moral approaches of the end ofthe 19th century as a pathological behaviour. The manuals which classify mental disorders, together with the notion of substance-related disorders, enable them to be approached with a medical vision. The subject of numerous, often heated or divisive debates, addictology requires a clinical approach.

[Alcoholic disease in women, what specificities?].

Alcoholic disease in women, what specificities? Alcoholic disease in women has long been neglected. Taboo, culturally, it has also probably been so in the field of research and on clinical practice. But this has changed since the recent publication of some very relevant studies that attracted particular attention from a part of the public opinion who came in support of professionals alarmed by the inaction on this subject.

[General principles of treatment in addictology].

General principles of treatment in addictology. Among all mental disorders, addictive pathologies are serious disorders. Their prognosis is severe.

[Epidemiology of alcohol dependence].

Excessive alcohol consumption is the second leading preventable cause of death in France (49,000/year), after tobacco consumption. Several recent studies found that the alcohol-related negative health consequences may occurs with small amounts of alcohol, in particular cancers. Therefore, the risk thresholds for alcohol consumption have been recently recommended not to be higher than 100g/week.

[Psychiatric comorbidities of Alcohol dependence].

Psychiatric disorders are common among patients with alcohol dependence. Symptoms of alcohol intoxication or withdrawal need to be disentangled from symptoms of psychiatric disorders. Alcohol dependence could induce psychiatric disorders, in particular depressive disorders and anxiety disorders.

ABCB1 C3435T polymorphism is associated with tetrahydrocannabinol blood levels in heavy cannabis users.

ABCB1 polymorphisms are known to modify drug pharmacokinetics but have yet to be studied for their role in generating and maintaining cannabis dependence. The objective of this study is to determine if ABCB1 C3435T (rs1045642) polymorphism may modulate Δ9-Tetrahydrocannabinol (THC) blood levels in a sample of heavy cannabis users. The study sample includes 39 Caucasian individuals, recruited in two French addictology centres, with isolated cannabis dependence and heavy use (defined as ≥ 7 joints per week).

Naltrexone in the Treatment of Broadly Defined Behavioral Addictions: A Review and Meta-Analysis of Randomized Controlled Trials.

Introduction: Broadly defined behavioral addiction is a conceptual framework including behaviors characterized by loss of control and continuation despite significant negative consequences. Broadly defined behavioral addictions share many similarities with substance use disorders. As naltrexone is one of the most studied treatment for substance use disorders, we conducted a meta-analysis of randomized placebo-controlled trials (RCT) assessing the effectiveness of naltrexone in the treatment of broadly defined behavioral addictions.

[Thiamine (vitamin B1) treatment in patients with alcohol dependence].

Thiamine deficiency (vitamin B1) is common in patients with alcohol dependence. Cognitive impairments may be an early consequence of thiamine deficiency. Wernicke's encephalopathy is underdiagnosed and undertreated.

Anxiety disorders are associated with early onset of heroin use and rapid transition to dependence in methadone maintained patients.

Early onset of heroin use is a severity marker of heroin use disorder. We studied the interaction between early onset and rapid transition to heroin dependence recorded with retrospective interviews in 213 patients with severe heroin dependence and history of methadone maintenance treatment. General linear models were used to identify independent factors associated with early onset, factors associated with rapid transition to dependence, and a multivariate model was used to study the interaction of those two dimensions.

[Smokers and psychiatric comorbidities].

The prevalence of smoking in patients with psychiatric disorders is higher than the prevalence of smoking in general population. Smokers with psychiatric disorders are at a greater risk for medical morbidity and mortality, including chronic obstructive pulmonary disease, cardiovascular disease, and cancers, compared to those in the general population. Their life expectancies are considerably reduced (25years).

[Cannabis-induced cognitive and psychiatric disorders].

Several studies have shown that Δ-9-THC the main psychoactive constituent of cannabis, can impair cognitive functions, especially attention, episodic memory, working memory and executive functions. These impairments have been related to the duration, frequency, dose and age at onset of cannabis use. Cognitive deficits may disappear with abstinence, but abnormalities may be long-lasting in subjects who began smoking cannabis before age 15.
