A call for mindfulness-based interventions for cannabis-use disorders.

Cannabis use is being increasingly liberalized worldwide, and an increasing prevalence of cannabis-use disorder (CUD) is observed. The few current therapeutic options for CUD are only modestly effective. Mindfulness-based interventions offer promising prospects for the management of substance-use disorders. However, despite proliferating literature on mindfulness and substance use, few studies have explored mindfulness in terms of cannabis use and CUD. There are many possibilities for the implementation of mindfulness-based interventions for cannabis use reduction, especially for younger users, who are more vulnerable to cannabis-related harms. Accordingly, large controlled trials are needed to reliably assess the potential of such interventions.

Screening for alcohol use in primary care: assessing French general practitioner practices.

Alcohol use is a leading risk factor for premature death and disability. To tackle this issue, more systematic and accurate screening for at-risk consumption is needed in healthcare systems, especially by general practitioners (GPs). We assessed the frequency of at-risk consumption screening by GPs in France. We also identified characteristics associated with more frequent screening and greater use of validated screening tools by these healthcare providers. A cross-sectional survey was conducted among a representative sample of French GPs. Multinomial logistic regressions were used to identify factors associated with more frequent screening and greater use of validated screening tools. Response rate was of 73%. Of the 2412 participants, 42.8% screened all their patients systematically and repeatedly, while 48.0% never used standardized tools to screen potentially at-risk patients. Among other characteristics, being aware of and using the "early identification and brief intervention" screening strategy, and feeling absolutely comfortable talking with patients about reducing or stopping their alcohol use, were both associated with more frequent screening and use of standardized tools. Our results on at-risk alcohol use screening highlight an improvement over data from previous studies. Nevertheless, better training of French GPs in good alcohol screening practices-specifically, increased screening frequency and greater use of standardized tools-may improve identification of at-risk patients.

Symptom severity is a major determinant of cannabis-based products use among people with multiple sclerosis.

AIMS AND OBJECTIVES: We aimed to identify correlates of cannabinoid-based products (CBP) use in patients with multiple sclerosis (MS) in France and Spain. BACKGROUND: MS is responsible for a wide range of symptoms, including pain. Access to CBP differs according to local legislation. The French context is more restrictive than the Spanish one, and no data regarding cannabis use among MS patients has yet been published. Characterizing MS patients who use CBP constitutes a first step toward identifying persons most likely to benefit from them. DESIGN: An online cross-sectional survey was submitted to MS patients who were members of a social network for people living with chronic diseases and were living in France or Spain. METHODS: Two study outcomes measured therapeutic CBP use and daily therapeutic CBP use. Seemingly unrelated bivariate probit regression models were used to test for associations between the outcomes and patients' characteristics while accounting for country-related differences. STROBE guidelines were followed in reporting this study. RESULTS: Among 641 study participants (70% from France), the prevalence of CBP use was similar in both countries (23.3% in France vs. 20.1% in Spain). MS-related disability was associated with both outcomes, with a gradient observed between different degrees of disability. MS-related pain level was associated with CBP use only. CONCLUSIONS: CBP use is common in MS patients from both countries. The more severe the MS, the more participants turned to CBP to alleviate their symptoms. Easier access to CBP should be ensured for MS patients in need of relief, especially from pain. RELEVANCE TO CLINICAL PRACTICE: This study highlights the characteristics of MS patients using CBP. Such practices should be discussed by healthcare professional with MS patients.

HCV cure: an appropriate moment to reduce cannabis use in people living with HIV? (ANRS CO13 HEPAVIH data).

BACKGROUND: Thanks to direct-acting antivirals, hepatitis C virus (HCV) infection can be cured, with similar rates in HCV-infected and HIV-HCV co-infected patients. HCV cure is likely to foster behavioral changes in psychoactive substance use, which is highly prevalent in people living with HIV (PLWH). Cannabis is one substance that is very commonly used by PLWH, sometimes for therapeutic purposes. We aimed to identify correlates of cannabis use reduction following HCV cure in HIV-HCV co-infected cannabis users and to characterize persons who reduced their use. METHODS: We used data collected on HCV-cured cannabis users in a cross-sectional survey nested in the ANRS CO13 HEPAVIH cohort of HIV-HCV co-infected patients, to perform logistic regression, with post-HCV cure cannabis reduction as the outcome, and socio-behavioral characteristics as potential correlates. We also characterized the study sample by comparing post-cure substance use behaviors between those who reduced their cannabis use and those who did not. RESULTS: Among 140 HIV-infected cannabis users, 50 and 5 had reduced and increased their use, respectively, while 85 had not changed their use since HCV cure. Cannabis use reduction was significantly associated with tobacco use reduction, a decrease in fatigue level, paying more attention to one's dietary habits since HCV cure, and pre-HCV cure alcohol abstinence (p = 0.063 for alcohol use reduction). CONCLUSIONS: Among PLWH using cannabis, post-HCV cure cannabis reduction was associated with tobacco use reduction, improved well-being, and adoption of healthy behaviors. The management of addictive behaviors should therefore be encouraged during HCV treatment.

Cannabidiol use and perceptions in France: a national survey.

BACKGROUND: Cannabidiol (CBD), a safe, non-intoxicating cannabis component, is growing in popularity in Europe and worldwide. However, CBD EU regulation is blurry, and consequent labelling and product quality issues may have implications for public health. There is therefore a need to assess the prevalence and perceived harmfulness of CBD use in EU countries, as well as to characterise CBD users. We aimed to do so in the French population. METHODS: In December 2021, an online survey was conducted in a sample respecting the French adult population structure for key demographic variables. Sociodemographic, behavioural and CBD perception data were collected. Three separate regressions were performed to identify correlates of i) having heard of CBD, ii) using CBD, iii) perceived harmfulness of CBD. A hierarchical classification was also performed to identify profiles of CBD users. RESULTS: The study sample comprised 1969 adults, of whom 69.2% had heard of CBD and 10.1% used it. Less than half (46.8%) of the former considered it harmful. Having heard of CBD was associated with younger age, being born in France, tobacco use, and cannabis use. CBD use was associated with younger age, tobacco use, cannabis use, poor self-reported general health status, and positive perception of alternative medicines. Cluster analysis revealed four different CBD user profiles based on socio-demographics and behavioural characteristics. CONCLUSION: Ten percent of the adults in this French study used CBD, and several user profiles emerged. Our results indirectly advocate clearer European CBD regulations to ensure safe and high-quality products.

Adherence to opioid agonist therapy predicts uptake of direct-acting antivirals in people who use drugs: results from the French national healthcare database (the ANRS FANTASIO study).

BACKGROUND: Opioid agonist therapy (OAT) is associated with reduced injection, reduced HCV transmission, and more opportunities to initiate hepatitis C virus (HCV) treatment in people who use drugs (PWUD). We aimed to study the extent to which adherence to OAT was predictive of increased uptake of direct-acting antivirals (DAA) in PWUD with chronic HCV infection. METHODS: Using the French national healthcare system database, we targeted PWUD (i.e. with a history of OAT) who had chronic HCV infection and were eligible for DAA during 2014-2016. Adherence to OAT was computed as a time-varying variable expressing the proportion of days covered by OAT receipt, over any six-month interval before DAA receipt. We used a Cox proportional hazards model to estimate the association between adherence to OAT and the rate of DAA uptake after adjustment for age, sex, alcohol use disorder, socioeconomic status, and liver disease severity. RESULTS: Among the 22,615 persons included in the ANRS FANTASIO study, 3438 (15.2%) initiated DAA during the study period. After multivariable adjustment, adherence to OAT was associated with a higher rate of DAA initiation. However, this association was not linear, and only individuals on OAT for 20% or more of the time in the previous six-month period had a higher rate of DAA initiation (adjusted hazard ratio [95% confidence interval]: 1.28 [1.18-1.38]). Other variables associated with DAA initiation were male sex, older age, cirrhosis or liver cancer, and higher socioeconomic status. CONCLUSIONS: Adherence to OAT is a major predictor of DAA initiation in PWUD living with chronic HCV infection in France. Our results also suggest that even moderate adherence to OAT can facilitate DAA uptake. Adequate HCV training for OAT prescribers together with interventions to ensure adherence to OAT will help improve DAA initiation rates and reach HCV elimination goals.

Evaluation of a novel therapeutic education programme for people with alcohol use disorder in France: a mixed-methods intervention study protocol (ETHER).

BACKGROUND: ETHER ("Education THEérapeutique pour la Réduction des dommages en alcoologie" or Therapeutic education for alcohol-related harm reduction) is a multicentre community-based mixed-methods study, which aims to evaluate the effectiveness of the innovative therapeutic patient education (TPE) programme 'Choizitaconso' in a sample of French people with alcohol use disorder (people with AUD). Choizitaconso teaches people with AUD psychosocial skills to help them (re)establish controlled drinking and reduce alcohol-related harms. Recruitment started in October 2019. We present here the protocol of the ETHER study. METHODS: ETHER's quantitative component involves a 6-month controlled intervention study which evaluates Choizitaconso's effectiveness by comparing 30 people with AUD following the programme with a control group of 60 people with AUD not enrolled in it, using a questionnaire co-constructed by the research team and members of the people with AUD community. Thirty-four alcohol-related harms are assessed and summed to provide an individual measure of the 'harm burden' from consuming alcohol (primary outcome). Secondary outcomes are anticipated and internalized stigma, alcohol consumption measures, craving for alcohol, coping strategies, health-related quality of life, self-confidence to control or abstain from drinking, treatment self-regulation, anxiety and depressive symptoms, alcohol-related neuropsychological impairments, and capabilities (a measure of wellbeing in adults). Data will be collected in face-to-face and phone-based interviews at enrolment and 6 months later. Linear regression models will be used to assess the impact of the TPE programme on changes in the primary and secondary outcomes, while adjusting for other correlates and confounders. The study's qualitative component comprises semi-structured interviews with 16 people with AUD who have already completed the TPE programme at least 6 months before the interview. Qualitative interviews will be analysed using thematic analysis. RESULTS AND CONCLUSIONS: ETHER is the first evaluation study of an innovative TPE programme specifically designed to reduce alcohol-related harms and reach controlled drinking in France. The involvement of the people with AUD community in selecting which experienced and perceived alcohol-related harms to measure ensures that ETHER will provide healthcare staff and researchers with a relevant set of harm reduction criteria for use in future research. Finally, ETHER will provide scientific justification for implementing novel alcohol-related harm reduction approaches and champion controlled drinking as a therapeutic goal.

Examining the Relationships between Mindfulness and Tobacco Craving Factors.

BACKGROUND: Relationships between mindfulness and general craving have been documented. However, there is still no data regarding relationships between mindfulness and the different craving factors. METHODS: Using data from an online survey among hospital workers smoking tobacco in France (n = 127), we performed linear regression models with the four craving factors as outcomes, and dispositional mindfulness as explanatory variable. RESULTS: After adjusting for nicotine dependence, mindfulness was negatively associated with general craving and three out of four craving factors (emotionality, compulsivity and purposefulness, but not expectancy). CONCLUSIONS: These results support the implementation of mindfulness-based interventions in the context of tobacco cessation attempt.

Elevated Fatty Liver Index as a Risk Factor for All-Cause Mortality in Human Immunodeficiency Virus-Hepatitis C Virus-Coinfected Patients (ANRS CO13 HEPAVIH Cohort Study).

BACKGROUND AND AIMS: Human immunodeficiency virus (HIV)-hepatitis C virus (HCV)-coinfected patients are at high risk of metabolic complications and liver-related events, which are both associated with hepatic steatosis and its progressive form, nonalcoholic steatohepatitis, a known risk factor for mortality. The fatty liver index (FLI), a noninvasive steatosis biomarker, has recently drawn attention for its clinical prognostic value, although its capacity to predict mortality risk in HIV-HCV-coinfected patients has never been investigated. Using a Cox proportional hazards model for mortality from all causes, with data from the French National Agency for Research on Aids and Viral Hepatitis CO13 HEPAVIH cohort (983 patients, 4,432 visits), we tested whether elevated FLI (≥60) was associated with all-cause mortality. APPROACH AND RESULTS: After multiple adjustment, individuals with FLI ≥ 60 had almost double the risk of all-cause mortality (adjusted hazard ratio [95% confidence interval], 1.91 [1.17-3.12], P = 0.009), independently of the following factors: HCV cure (0.21 [0.07-0.61], P = 0.004), advanced fibrosis (1.77 [1.00-3.14], P = 0.05), history of hepatocellular carcinoma and/or liver transplantation (7.74 [3.82-15.69], P < 10-3 ), history of indirect clinical signs of cirrhosis (2.80 [1.22-6.41], P = 0.015), and HIV Centers for Disease Control and Prevention clinical stage C (2.88 [1.74-4.79], P < 10-3 ). CONCLUSIONS: An elevated FLI (≥60) is a risk factor for all-cause mortality in HIV-HCV-coinfected patients independently of liver fibrosis and HCV cure. In the present era of nearly 100% HCV cure rates thanks to direct-acting antivirals, these findings encourage the more systematic use of noninvasive steatosis biomarkers to help identify coinfected patients with higher mortality risk.

HCV Cure and Cannabis Abstinence Facilitate Tobacco Smoking Quit Attempts in HIV-HCV Co-Infected Patients (ANRS CO13 HEPAVIH Cohort Study).

In Western countries, tobacco smoking is highly prevalent among patients co-infected with HIV and hepatitis C virus (HCV). In the era of antiretrovirals and HCV cure, smoking-related health damages contribute greatly to morbidity and mortality in HIV-HCV co-infected patients. We used longitudinal data from the ANRS CO13 HEPAVIH cohort to identify the correlates of tobacco smoking quit attempts (TSQA) in HIV-HCV co-infected patients. TSQA were modelled using a multivariable discrete-time Cox proportional hazards model in 695 HIV-HCV co-infected tobacco smokers. HCV cure was associated with a 76% higher chance of TSQA (adjusted hazard ratio [95% confidence interval]: 1.76 [1.06-2.93], p = 0.029), and cannabis use with a 37% lower chance (0.63 [0.40-1.00], p = 0.049), independently of the mode of HIV transmission, other psychoactive substance use, and body mass index. Patients should be screened for tobacco and cannabis use at HCV treatment initiation and during follow-up. They should also be provided with comprehensive counselling and referral to addiction services. Non-smoking routes of cannabis administration should be promoted for cannabis users who wish to quit smoking tobacco.

Cannabis use is associated with a lower risk of diabetes in chronic hepatitis C-infected patients (ANRS CO22 Hepather cohort).

Chronic hepatitis C virus (HCV) infection is a risk factor of insulin resistance, and HCV-infected patients are at a high risk of developing diabetes. In the general population, research has shown the potential benefit of cannabis use for the prevention of diabetes and related metabolic disorders. We aimed to test whether cannabis use is associated with a lower risk of diabetes in chronic HCV-infected patients. Chronic HCV-infected patients (n = 10 445) were selected from the French national, multicenter, observational ANRS CO22 Hepather cohort. Cross-sectional data collected at cohort enrollment were used to assess the association between patients' clinical and behavioural characteristics and the risk of diabetes. Logistic regression model was performed with cannabis use as the main independent variable and a significance level set at 5%. A similar model stratified by the presence of advanced liver fibrosis (FIB-4 > 3.25) was also run. After multivariable adjustment, current (AOR [95%CI]: 0.49 [0.38-0.63]) and former (0.81 [0.67-0.98], P < .001) cannabis use were both associated with a reduced odds of diabetes. Conversely, male gender, tobacco use, elevated BMI, poverty, being a migrant and advanced fibrosis were associated with increased odds of diabetes. The association between cannabis use and diabetes was maintained in the stratified analysis. In this large cross-sectional study of chronic HCV-infected patients, cannabis use was associated with a lower risk of diabetes independently of clinical and socio-behavioural factors. Further studies are needed to elucidate a potential causal link and shed light on cannabis compounds and mechanisms involved in this relationship.

Screening and care for alcohol use disorder in France: expectations, barriers and levers using a mixed-methods approach.

BACKGROUND: The widespread under-screening and under-treatment of alcohol use disorder (AUD) contributes to its health and socioeconomic burden. We conducted a mixed-methods (qualitative and qualitative) study in people with alcohol use disorder (PWAUD) to explore their expectations, as well as barriers and levers to AUD care. METHODS: Individuals with AUDIT > 15 (N = 179) were interviewed using computer-assisted interviews in several medical and non-medical sites (e.g., bars) (quantitative substudy). We also conducted semi-structured face-to-face interviews with 36 PWAUD (qualitative substudy). Using logistic regression, we explored factors associated with having previously received/sought care for AUD. Three major themes were identified in the qualitative textual analysis using a descending hierarchical classification. RESULTS: Not socializing with heavy drinkers (AOR [95%CI]:3.84[1.66-8.85]), regular smoking (9.72[3.91-24.15]) and feeling discriminated against (2.35[1.10-5.05]) were independent levers to having sought/received care for AUD, while being aged < 50 and employment were independent barriers. The five predominant themes in PWAUD discourses emerging from the textual analysis were: drinking context, medical care, alcohol treatment, tobacco/addiction and family. When triangulating results from the logistic regression and the textual analysis, two barriers (social drinking and difficulties with the medical care system), and two levers (family influence and tobacco addiction), emerged. CONCLUSION: These results underline the need for interventions targeting families and the social network to increase awareness about AUD and related care. Simplified and novel comprehensive care trajectories are urgently needed to reduce the clinical and public health burden of AUD.

Reaching Nutritional Adequacy Does Not Necessarily Increase Exposure to Food Contaminants: Evidence from a Whole-Diet Modeling Approach.

BACKGROUND: Dietary guidelines are designed to help meet nutritional requirements, but they do not explicitly or quantitatively account for food contaminant exposures. OBJECTIVE: In this study, we aimed to test whether dietary changes needed to achieve nutritional adequacy were compatible with acceptable exposure to food contaminants. METHODS: Data from the French national dietary survey were linked with food contaminant data from the French Total Diet Study to estimate the mean intake of 204 representative food items and mean exposure to 27 contaminants, including pesticides, heavy metals, mycotoxins, nondioxin-like polychlorinated biphenyls (NDL-PCBs) and dioxin-like compounds. For each sex, 2 modeled diets that departed the least from the observed diet were designed: 1) a diet respecting only nutritional recommendations (NUT model), and 2) a diet that met nutritional recommendations without exceeding Toxicological Reference Values (TRVs) and observed contaminant exposures (NUTOX model). Food, nutrient, and contaminant contents in observed diets and NUT and NUTOX diets were compared with the use of paired t tests. RESULTS: Mean observed diets did not meet all nutritional recommendations, but no contaminant was over 48% of its TRV. Achieving all the nutrient recommendations through the NUT model mainly required increases in fruit, vegetable, and fish intake and decreases in meat, cheese, and animal fat intake. These changes were associated with significantly increased dietary exposure to some contaminants, but without exceeding 57% of TRVs. The highest increases were found for NDL-PCBs (from 26% to 57% of TRV for women). Reaching nutritional adequacy without exceeding observed contaminant exposure (NUTOX model) was possible but required further departure from observed food quantities. CONCLUSIONS: Based on a broad range of nutrients and contaminants, this first assessment of compatibility between nutritional adequacy and toxicological exposure showed that reaching nutritional adequacy might increase exposure to food contaminants, but within tolerable levels. However, there are some food combinations that can meet nutritional recommendations without exceeding observed exposures.

How low can dietary greenhouse gas emissions be reduced without impairing nutritional adequacy, affordability and acceptability of the diet? A modelling study to guide sustainable food choices.

OBJECTIVE: To assess the compatibility between reduction of diet-related greenhouse gas emissions (GHGE) and nutritional adequacy, acceptability and affordability dimensions of diet sustainability. DESIGN: Dietary intake, nutritional composition, GHGE and prices were combined for 402 foods selected among those most consumed by participants of the Individual National Study on Food Consumption. Linear programming was used to model diets with stepwise GHGE reductions, minimized departure from observed diet and three scenarios of nutritional constraints: none (FREE), on macronutrients (MACRO) and for all nutrient recommendations (ADEQ). Nutritional quality was assessed using the mean adequacy ratio (MAR) and solid energy density (SED). SETTING: France. SUBJECTS: Adults (n 1899). RESULTS: In FREE and MACRO scenarios, imposing up to 30 % GHGE reduction did not affect the MAR, SED and food group pattern of the observed diet, but required substitutions within food groups; higher GHGE reductions decreased diet cost, but also nutritional quality, even with constraints on macronutrients. Imposing all nutritional recommendations (ADEQ) increased the fruits and vegetables quantity, reduced SED and slightly increased diet cost without additional modifications induced by the GHGE constraint up to 30 % reduction; higher GHGE reductions decreased diet cost but required non-trivial dietary shifts from the observed diet. Not all the nutritional recommendations could be met for GHGE reductions ≥70 %. CONCLUSIONS: Moderate GHGE reductions (≤30 %) were compatible with nutritional adequacy and affordability without adding major food group shifts to those induced by nutritional recommendations. Higher GHGE reductions either impaired nutritional quality, even when macronutrient recommendations were imposed, or required non-trivial dietary shifts compromising acceptability to reach nutritional adequacy.
