Determinants of Dropout From a Virtual Agent-Based App for Insomnia Management in a Self-Selected Sample of Users With Insomnia Symptoms: Longitudinal Study.

Background: Fully automated digital interventions delivered via smartphone apps have proven efficacious for a wide variety of mental health outcomes. An important aspect is that they are accessible at a low cost, thereby increasing their potential public impact and reducing disparities. However, a major challenge to their successful implementation is the phenomenon of users dropping out early.

Craving changes in first 14 days of addiction treatment: an outcome predictor of 5 years substance use status?

Addiction is considered a chronic disorder that requires long-term treatment. Early identification of predictors of outcome may enable better and early adjustment of treatment. Daily fluctuations of craving have been shown to predict substance use within hours, making it a major target for treatment.

Medications for Opioid Use Disorder in People Who Inject Substances: Reflection on the Potential Place of Morphine Sulfate as Substitution Treatment? Results of COSINUS Cohort Study.

Background: Opioid Use Disorder (OUD) often provokes dramatic consequences in terms of increased morbi-mortality. Two medications have mainly been worldwide used for OUD (MOUD), buprenorphine and methadone. Recently, however, some reports have highlighted the use of Morphine Sulfate (MS) mainly obtained without a prescription but used as MOUD by opioid users and especially People Who Inject Substances (PWIS).

Exploring and describing alcohol harm reduction interventions: a scoping review of literature from the past decade in the western world.

Context: Regular alcohol use is a predominant risk factor for disease, injury, and social harm. While robust evidence is advocating for implementing interventions to reduce the harms of illegal substance use, less literature is dedicated to identifying and understanding interventions aiming at reducing the various harms associated with alcohol.

Objectives: This review describes how alcohol harm reduction (AHR) interventions are currently conducted and analyzes the facilitators and barriers identified by the studies on their efficacy.

Effectiveness evaluation of an organisational intervention, targeting pregnancy and addiction care professionals, among women who have just given birth in maternity wards and smoked tobacco during pregnancy (5A-QUIT-N): study protocol for a stepped-wedge cluster randomised trial.

Introduction: In 2021, among French women who smoked when they knew they were pregnant, 59% still smoked at the end of pregnancy. Support for pregnant women to stop smoking must include a structured organisational perspective. The main objective of the study is to evaluate the effectiveness of the 5A-QUIT-N organisational intervention on smoking cessation at delivery among pregnant women who smoke during pregnancy.

Making alcohol and tobacco preventable deaths truly preventable! Addiction as a modifiable risk factor for alcohol and tobacco preventable mortality.

Worldwide, health professionals from all specialties are encouraging patients to reduce alcohol use if not abstain, and abstinence is clearly encouraged for tobacco. However, for users of substances that meet diagnostic criteria for substance use disorder (addiction), reducing use or abstaining will be difficult without appropriate addiction treatment. Moreover, this group is the most at risk and the most likely to benefit from reducing use.

Predictors of substance use during treatment for addiction: A network analysis of ecological momentary assessment data.

Background And Aims: Ecological momentary assessment (EMA) studies have previously demonstrated a prospective influence of craving on substance use in the following hours. Conceptualizing substance use as a dynamic system of causal elements could provide valuable insights into the interaction of craving with other symptoms in the process of relapse. The aim of this study was to improve the understanding of these daily life dynamic inter-relationships by applying dynamic networks analyses to EMA data sets.

Identifying the role of (dis)inhibition in the vicious cycle of substance use through ecological momentary assessment and resting-state fMRI.

Functional inhibition is known to improve treatment outcomes in substance use disorder (SUD), potentially through craving management enabled by underlying cerebral integrity. Whereas treatment is challenged by a multitude of substances that patients often use, no study has yet unraveled if inhibition and related cerebral integrity could prevent relapse from multiples substances, that is, one's primary drug of choice and secondary ones. Individuals with primary alcohol, cannabis, or tobacco use disorders completed intensive Ecological Momentary Assessment (EMA) coupled with resting-state functional MRI (rs-fMRI) to characterize the extent to which inhibition and cerebral substrates interact with craving and use of primary and any substances.

Cost-effectiveness of drug consumption rooms in France: a modelling study.

Background: People who inject drugs (PWID) experience many health problems which result in a heavy economic and public health burden. To tackle this issue, France opened two drug consumption rooms (DCRs) in Paris and Strasbourg in 2016. This study assessed their long-term health benefits, costs and cost-effectiveness.

[Anorexia nervosa: An addiction? Application of the addiction model to eating disorders. A narrative commented review].

Objectives: Addiction offers a framework for the understanding of eating disorders, particularly those characterized by hyperphagia, with growing interest in food addiction. However, the application of the addiction model to anorexia nervosa remains more controversial. In this commented narrative review, we examine and discuss the addictive features of anorexia nervosa.

Multi-level prediction of substance use: Interaction of white matter integrity, resting-state connectivity and inhibitory control measured repeatedly in every-day life.

Substance use disorders are characterized by inhibition deficits related to disrupted connectivity in white matter pathways, leading via interaction to difficulties in resisting substance use. By combining neuroimaging with smartphone-based ecological momentary assessment (EMA), we questioned how biomarkers moderate inhibition deficits to predict use. Thus, we aimed to assess white matter integrity interaction with everyday inhibition deficits and related resting-state network connectivity to identify multi-dimensional predictors of substance use.

Gender and Drug Use Discrimination Among People Who Inject Drugs: An Intersectional Approach Using the COSINUS Cohort.

Purpose: Injection drug use is strongly associated with stigmatization by loved ones, healthcare providers, and society in general. This stigmatization can have negative consequences on the health of people who inject drugs (PWID) and limit their access to care. Women who inject drugs face greater stigma than men because of gendered social norms and the intersectional effect between gender and drug use identities.

Craving dynamics and related cerebral substrates predict timing of use in alcohol, tobacco, and cannabis use disorders.

Background: Patients treated for Substance Use Disorders exhibit highly fluctuating patterns of craving that could reveal novel prognostic markers of use. Accordingly, we 1) measured fluctuations within intensively repeated measures of craving and 2) linked fluctuations of craving to connectivity indices within resting-state (rs) brain regions to assess their relation to use among patients undergoing treatment for Alcohol, Tobacco and Cannabis Use Disorders.

Method: Participants -64 individuals with SUD for tobacco, alcohol, or cannabis and 35 healthy controls-completed a week of Ecological Momentary Assessment (EMA) during which they reported craving intensity and substance use five times daily.

A video-based intervention to overcome pregnancy smoking stigma among healthcare students: a randomised controlled trial.

Objectives: This study tests a video intervention to reduce pregnancy smoking stigma among French healthcare students.

Design: The participants were randomly selected to watch online either an experimental video (presenting educational content regarding stigma and contact with pregnant smokers) or a control video (presenting standard educational content about the risks of smoking). The students completed scales assessing stigma, intention to address smoking cessation and self-efficacy to do so, before the intervention (T0,  = 252), one week after the intervention (T1,  = 187), and one month after the intervention (T2,  = 131).

The stigma of smoking among women: A systematic review.

Background: Smoking stigma has been well documented, but little is known regarding its specific features and effects on women. Notably, women face unique social, cultural, and economic challenges that may interact with smoking stigma and impact health outcomes. This review investigates the extent to which smoking women encounter and internalise stigma, while examining the various coping mechanisms they employ to manage these negative experiences.

Stigmatization of people with addiction by health professionals: Current knowledge. A scoping review.

Background: Stigma of people with substance and non-substance use disorders (SNSUD) is a long-known phenomenon. The aim of this review was to assess the stigmatization, by health professionals, of people with SNSUD, its characteristics and change over time.

Methods: A scoping review of literature reviews was conducted with systematic search of PubMed, Scopus and PsycINFO databases.

Drug consumption rooms are effective to reduce at-risk practices associated with HIV/HCV infections among people who inject drugs: Results from the COSINUS cohort study.

Aims: The primary aim of this study was to evaluate the impact of drug consumption rooms (DCRs) in France on injection equipment-sharing, while the secondary aims focused upon their impact on access to hepatitis C virus (HCV) testing and opioid agonist treatment (OAT).

Design: The COhort to identify Structural and INdividual factors associated with drug USe (COSINUS cohort) was a 12-month longitudinal study of 665 people who inject drugs (PWID), conducted in Bordeaux, Marseille, Paris and Strasbourg. We used data from face-to-face interviews at enrolment and at 6-month and 12-month visits.

Predictors of users' adherence to a fully automated digital intervention to manage insomnia complaints.

Objective: Fully automated digital interventions show promise for disseminating evidence-based strategies to manage insomnia complaints. However, an important concept often overlooked concerns the extent to which users adopt the recommendations provided in these programs into their daily lives. Our objectives were evaluating users' adherence to the behavioral recommendations provided by an app, and exploring whether users' perceptions of the app had an impact on their adherence behavior.

Does food use disorder exist? Item response theory analyses of a food use disorder adapted from the DSM-5 substance use disorder criteria in a treatment seeking clinical sample.

Background: Increased consumption of food that are high in energy and sugar have been pointed as a major factor in the obesity epidemic. Impaired control of food intake and the concept of food addiction has been developed as a potential contributor. Our objective was to evaluate the dimensionality and psychometric validity of diagnostic criteria for food addiction adapted from the 11 DSM-5 substance use disorder (SUD) criteria (i.

The Pregnant Smoker Stigma Scale - Self Stigma (P3S-SS): development and validation in pregnant smoking women in France.

Pregnancy smoking self-stigma may be associated with mental health and smoking cessation. This study aims to validate the Pregnant Smoker Stigma Scale - Self-Stigma (P3S-SS) assessing perceived and internalized stigma. Between May 2021 and May 2022, French pregnant smokers recruited online ( = 143) took the P3S-SS and other scales assessing depressive symptoms (EPDS), social inclusion (SIS), dissimulation, dependence (CDS-5), cessation self-efficacy (SEQ), and intention.

The Craving-Manager smartphone app designed to diagnose substance use/addictive disorders, and manage craving and individual predictors of relapse: a study protocol for a multicenter randomized controlled trial.

Background: The rate of individuals with addiction who are currently treated are low, and this can be explained by barriers such as stigma, desire to cope alone, and difficulty to access treatment. These barriers could be overcome by mobile technologies. EMI (Ecological Momentary Intervention) is a treatment procedure characterized by the delivery of interventions (messages on smartphones) to people in their daily lives.

The centrality of craving in network analysis of five substance use disorders.

Background And Aims: Among the 11 current diagnostic criteria, craving is a potential central marker for understanding and for treatment of Substance Use Disorders (SUD). Our objective was to explore craving centrality across SUD based on the study of symptom interactions in cross-sectional network analyses of DSM-5 SUD diagnostic criteria. We hypothesized the centrality of "Craving" in SUD across substance types.
