RESUMEN
BACKGROUND AND OBJECTIVES: Cocaine is a highly addictive substance, and with no approved medication for cocaine use disorder (CUD), leading to a heavy burden. Despite validated psychosocial treatments, relapse rates after detoxification are very high in CUD. Few consistent factors can predict abstinence after detoxification. Our study, therefore, aimed at identifying factors predicting abstinence among CUD patients after inpatient detoxification. METHODS: Eighty-one CUD inpatients were included during detoxification and characterized for clinical and sociodemographic data at baseline and at a follow-up of 3 months after discharge, including a standard measure of their abstinence duration from cocaine. We performed Cox univariate analyzes to determine the factors associated with abstinence maintenance, followed by a multivariate Cox regression to identify independent predictors. RESULTS: Abstinence maintenance was shorter in patients injecting cocaine (hazard ratio [HR] = 5.16, 95% confidence interval [CI]: 2.01-13.27, p < .001) and using cocaine heavily in the month before inclusion (HR = 1.03, 95% CI: 1.00-1.06, p = .046). Conversely, abstinence maintenance was longer in patients with longer inpatient detoxification stays (HR = 0.96, 95% CI: 0.94-0.99, p = .015) and prescribed with selective serotonin reuptake inhibitors (SSRIs) (HR = 0.30, 95% CI: 0.16-0.56, p < .001). DISCUSSION AND CONCLUSIONS: Patients with severe CUD may require longer inpatient stays to achieve abstinence. Regarding SSRI prescription, more specific studies are needed to provide stronger recommendations about their use in clinical practice. SCIENTIFIC SIGNIFICANCE: Our findings suggest several modifiable factors to improve inpatient treatment response in CUD. As there are no specific recommendations about the optimal duration of inpatient stay, our results could pave the way for evidence-based guidelines.

OBJECTIVES: Anxiety and depressive symptoms, as well as cognitive dysfunctions, improve with abstinence in individuals with alcohol use disorders (AUD), but less is known about psychotic features. The objective of this study was to evaluate the psychosis proneness in a sample of individuals with severe AUD and potential changes after alcohol withdrawal. METHOD: An observational study was conducted, assessing prospectively Peter's Delusional Inventory scale (PDI); anxiety and depression symptoms by MADRS and cognitive functioning by the MoCA at entry in daycare hospital (D0) and after 30 days (D30). Individuals with schizophrenia, chronic delusional disorder and bipolar disorder were excluded. Wilcoxon tests were used to evaluate the evolution between D0 and D30, and linear regressions were conducted to test the association between delta PDI and the variables that could be potential confounders. RESULTS: Forty individuals (72% males) with a mean age of 50 ± 9 years old and AUD evolved for 15 ± 11 years were included. After one month, PDI score decreased significantly (p = .001), and several biological and clinical parameters improved significantly with abstinence or consumption reduction: GGT (p = .003), MoCA (p < .001), MADRS (p = .047). CONCLUSION: We observed a decrease in delusional thinking along abstinence and/or consumption reduction. To our knowledge, this is the first research to study psychosis proneness evolution in patients with severe AUD. Replications are required in independent samples with larger sample size.
RESUMEN
In this translational study, we investigated the plasma tau protein, neurofilament light chain (NfL), glial fibrillary acidic protein (GFAP) and ubiquitin carboxy-terminal hydrolase L1 (UCHL1), which are established biomarkers of neurological injury, as predictive biomarkers of alcohol withdrawal-associated brain toxicity. In the clinical study, patients with severe alcohol use disorder (AUD) on D1 of hospitalization for alcohol cessation (AC) (N = 36) were compared to severe AUD patients with at least 3 months of abstinence (N = 16). Overall, patients were 40 men (76.9%), aged 49.8 years [SD ±9.9]. Tau, NfL, GFAP and UCHL1 levels were measured using SIMOA and analysed with a quasipoisson regression model adjusted for age and sex. The NfL level was higher in the AC group (p = 0.013). In the AC group, the tau (p = 0.021) and UCHL1 (p = 0.021) levels were positively associated with the dose of diazepam per weight, and the tau (p = 0.045), NfL (p = 4.9 × 10-3 ) and UCHL1 (p = 0.036) levels were higher in the presence of signs of Wernicke's encephalopathy (n = 9). In the preclinical study, NfL and GFAP levels were assessed in the alcohol deprivation effect (ADE) procedure (N = 17) and control Wistar rats (N = 15). Furthermore, ADE rats were prospectively assessed: after 24 h (T1) and 3 weeks of AC (T2) (paired-samples Wilcoxon and Mann-Whitney tests). The NfL level was higher in the ADE model than in the control rats at both T1 and T2 (p = 0.033 and p = 1.3 × 10-3 ) and higher at T2 than at T1 (p = 0.040). Plasma tau, NfL and UCHL1 are potential biomarkers of brain suffering during alcohol withdrawal.

BACKGROUND: The prevalence of cognitive impairment is high among alcohol-dependent patients. Although the clinical presentation of alcohol-related cognitive disorder (ARCD) may resemble that of Alzheimer's disease (AD), the prognosis and treatment of the 2 diseases are different. Cerebrospinal fluid (CSF) biomarkers (tau, phosphorylated tau, and amyloid ß) have high diagnostic accuracy in AD and are currently being used to discriminate between psychiatric disorders and AD, but are not used to diagnose ARCD. The aim of this study was to characterize CSF biomarkers in a homogeneous, cognitively impaired alcohol-dependent population. METHODS: This single-center study was conducted in an addiction medicine department of a Parisian Hospital. We selected patients with documented persistent cognitive impairment whose MoCA (Montreal Cognitive Assessment) score was below 24/30 after at least 1 month of documented inpatient abstinence from alcohol. We measured the CSF biomarkers (tau, phosphorylated tau, and amyloid ß 1-42 and 1-40) in 73 highly impaired alcohol-dependent patients (Alcohol Use Disorders Identification Test score over 11 for women and 12 for men) with. RESULTS: Patients' average age was 60 ± 9.1 years and 45 (61.6%) had a normal CSF profile, 8 (11.0%) had a typical CSF AD profile, and 20 (27.4%) had an intermediate CSF profile. CONCLUSIONS: This study revealed a high prevalence of AD in alcohol-dependent patients with persistent cognitive deficits and several anomalies in their CSF profiles. Thus, it is important to consider AD in the differential diagnosis of persistent cognitive deficits in patients with alcohol dependence and to use CSF biomarkers in addition to imaging and neuropsychological testing to evaluate alcohol-related cognitive impairment.

PURPOSE: Brain positron emission tomography using 18F-fluorodeoxyglucose (18FDG-PET) provides a metabolic assessment of brain function that is useful for differential diagnosis among several neurodegenerative diseases manifested by cognitive impairment (CI). The purpose of the study is to describe the pattern of 18FDG-PET abnormalities in patients with CI related to alcohol use disorder. METHODS: Patients admitted to the addiction medicine department of a university hospital in Paris between January 2017 and October 2018 with a confirmed diagnosis of alcohol-related cognitive impairment (ARCI) or Wernicke encephalopathy (WE) were included. Brain 18FDG-PET uptake was measured after at least 1 month of monitored abstinence from alcohol. Standardized uptake values were obtained for 13 regions of interest (ROI) and normalized to the pons. Individual patients' ROI Z-scores were calculated from healthy sex- and age-matched controls provided by Cortex ID software. RESULTS: Twenty-five patients were included in the analysis (20 males and 5 females; mean age 57.6 years (45-76 years old)). The group consisted of 19 ARCI and 6 WE cases. The mean hypometabolism was most severe in the prefrontal medial cortex (PFM) (- 2.80 (± 1.30)), the prefrontal lateral cortex (- 2.20 (± 1.35)), and the anterior cingulate cortex (- 2.24 (± 1.19)). Hypometabolism (Z-score < - 2) was most frequent in the PFM (72.0% of the sample, N = 18). Other regions were also affected (with 5.32/13 hypometabolic ROIs on average (SD = 4.16, range 0-13)). The Z-scores in the 13 ROIs did not differ significantly between the ARCI and WE patients (p ≥ 0.05). CONCLUSIONS: Predominant prefrontal and cingulate cortex hypometabolism was the most frequent brain 18FDG-PET pattern in our sample of patients with ARCI and WE.

Providing an on-site immediate diagnosis of Chronic Obstructive Pulmonary Disease (COPD) and lung age in tobacco smokers could be a motivational tool for smoking cessation. Our aim was to investigate the effects of an abnormal spirometry results on motivational change and subsequent smoking cessation. We conducted a retrospective analysis of smoking status after 3 months of tobacco counseling. Patients were recruited in an addiction outpatient center. Spirometry results were obtained with a portable device during the first visit. The sample was thus divided in 3 groups: COPD, subthreshold-group (no COPD but abnormal lung age) and normal spirometry. Among the three groups, we compared the immediate motivation change, difference in Q-MAT motivation scale score after minus before spirometry (Kruskal-Wallis test) and the smoking status after 3 months (Fisher test). We included 48 patients (37 males, median age 44 years, median cigarette-per-day 20). Spirometry results divided the sample in COPD (N = 13), subthreshold (N = 11) and normal group (N = 24). Mean Q-MAT score change after spirometry was different between groups (p = 0.019), greater in COPD (4.62 ± 3.38) than normal group (1.46 ± 3.11), and lower in patient with a co-occuring hazardous alcohol use (p = 7.6 × 10-3). Three-months smoking status was different between spirometry results groups (p = 0.0021). COPD (5/13, 38.5%) and subthreshold patients (6/10, 60.0%) had stopped more frequently than patients from the normal-group (2/22, 9.1%). The effect of immediate spirometry results on motivation to quit varies according to the screened pulmonary damages and hazardous alcohol use. It could be a useful tool in addiction treatment centers.

PURPOSE: Individual and family characteristics early on in life are associated with adolescent smoking; however, their role with regard to long-term tobacco smoking trajectories into young adulthood is not well-known, which is what we set out to study using data from a longitudinal community-based cohort. METHODS: We used data from 2,025 youths in France (12-26 years at baseline, 16 years of follow-up), participating in the longitudinal TEMPO cohort study. First, we modeled smoking trajectories from adolescence onwards using Group-Based Trajectory Modeling, by using the declared consumption of cigarettes at different ages. Second, among trajectories of smokers, associations with individual and family characteristics in childhood and adolescence were studied using multinomial logistic regression. RESULTS: We observed 5 smoking trajectories: non-smokers (62.3%), 3 groups of persistent smokers with different levels of tobacco use (low, intermediate, high), and a group characterized by high-level smoking followed by cessation. Among participants who were lifetime smokers (n = 763), the trajectory of tobacco use was associated with early substance use initiation, academic attainment, grade retention, and parental smoking. Early tobacco and cannabis use initiation predicted high-level tobacco use, whether it persisted (OR 2.29, 95% CI 1.23-4.28) or not (OR 2.99, 95% CI 1.59-5.63). Grade retention and parental smoking predicted persistent smoking of intermediate (respectively OR 1.53, 95% CI 1.03-1.92; OR 1.74, 95% CI 1.03-2.92) or high level use (respectively OR 1.74, 95% CI 1.07-2.85; OR 1.70, 95% CI 0.91-3.18). Poor academic attainment predicted all 3 smoking trajectories, especially persistent high-level smoking (no high school degree: OR 5.29, 95% CI 1.65-16.97, vocational degree: OR 1.94, 95% CI 0.99-3.80). CONCLUSIONS: Tobacco smoking trajectories from adolescence to adulthood are associated with early substance use initiation, parental smoking, and academic difficulties.

BACKGROUND: On the brink of the opening of the first French drug consumption room in Paris, the general opinion of the local involved health care professionals and drug users was not known. The objective of this study was to determine their expectations and to search for influencing factors. METHOD: We carried out a quantitative cross-sectional study. A multiple choice questionnaire was proposed to the surrounding willing general practitioners (GPs) and pharmacists, to the emergency doctors of Lariboisière hospital, and to the professionals of the harm reduction facilities and their drug users (PWUD). For each question, there was a choice between seven answers, from "- 3" (very negative impact) to "+ 3" (very positive impact). The influence of the characteristics of each group on its mean answers was explored by Mann-Whitney, Kruskal-Wallis, and Spearman's tests. RESULTS: The median expectations among the groups of responding GPs (N = 62), other health care professionals (N = 82), and PWUD (N = 57) were mainly positive. They thought that the drug consumption room (DCR) would improve the health of PWUD, reduce their at-risk behaviors, would not increase drug use or drug dealing in the neighborhood, and would reduce nuisance in the public space. Only the group of GPs expressed that the DCR could decrease the quietness of the neighborhood, and only the group of PWUD had higher expectations that the DCR would decrease the number of arrests and the number of violent behavior. GPs' expectations were significantly better in terms of health improvement of PWUD and reducing their precariousness if they had a previous experience in addiction medicine (Mann-Whitney, p = 0.004 and p = 0.019), with a longer practice (Spearman's rho, p = 0.021 and p = 0.009), and if they were currently prescribing opioid substitution treatments (Mann-Whitney, p = 0.030 and p = 0.002). Among non-GPs, those who were working in addiction medicine centers had significantly better expectations than pharmacists, and the professionals of the local emergency department had intermediate expectations. CONCLUSIONS: Health care professionals and drug users had a positive opinion of the to-be-created Parisian drug consumption room. Experience in addiction medicine influenced positively health professionals' expectations.

BACKGROUND: Studies on contraceptive use by patients with substance use disorders (SUD) show a concerning low use of contraception. Mainly conducted in USA, they could be irrelevant to patients attending European SUD treatment centers, especially since these studies mostly investigate women suffering from social exclusion, severe material deprivation andopiates use with frequent high-risk drug use and sexual behaviors including sex trade, frequently not currently attending treatment centers. The purpose of this study is to describe contraceptive use by patients, both male and female, since contraception can not only be considered as a female problem, with severe SUD in two free clinics in Paris, France. METHODS: An anonymous self-report questionnaire was distributed to literate patients followed in two generalist substance use disorders treatment centers in hospitals of Paris, France: Espace Murger and Centre Cassini, during 5 weeks between February and March 2016. RESULTS: Out of the 78 respondents (with an age mean 40.7 years, in which women are represented as 48.1%, and 29.7% of them have children), 53 have had at least one sexual partner in the last 6 months. Contraception was "always" used by 55.3% of sexually active patients, "sometimes" by 19.1%, and "not" used by 25.5%. Male condoms were the main contraceptive method. The use of intrauterine devices was low, contrarily to what is observed in the French general population. However, the knowledge of contraceptive methods was common. CONCLUSIONS: In this population, with a high prevalence of at risk sexual behavior, the use of contraceptive methods is lower than in French general population. During standard care for SUD, contraception and desire to be a parent should be discussed and patients empowered to make their own choices. Lack of knowledge does not seem to be a hindrance to the use of contraception, but other sociological, psychological, or medical factors may limit contraceptive access and long-term use, especially for the long-acting reversible contraception methods. It is necessary to further develop this reflection by discussing the individual contraceptive choices with the patients themselves to clarify the nature of these constraints and maybe provide several contraceptive methods within the SUD care settings.

BACKGROUND: Cognitive impairments are common in patients with AUD and worsen the prognosis of addiction management. There are no clear guidelines for screening cognitive impairments in hospitalized patients with AUD. METHODS: Fifty-seven patients with an AUD history who were admitted to an acute hospital and assessed by the addiction care team were included. Those patients were screened for cognitive impairments using the Montreal Cognitive Assessment (MoCA) test. We collected clinical information regarding addiction history, comorbidities, and current treatments. Chi-square tests, t-tests, and Mann-Whitney tests were performed to determine factors associated with a pathological MoCA score (<26). RESULTS: A pathological MoCA score was positively associated with spatial-temporal disorientation, difficulty in recalling addiction history, patient underreporting of AUD and a date of last alcohol consumption lower than 11 days ago, and negatively associated with a reason for hospitalization due to alcohol-related health issues. No medication was associated with cognitive impairments. CONCLUSIONS: Clinical elements from assessment by the addiction care team allow for relevant indication for screening cognitive impairments.

AIMS: Cocaine Use Disorder (CUD) is an important health issue, associated with structural brain abnormalities. However, the impact of the route of administration and their predictive value for relapse remain unknown. METHODS: We conducted an anatomical MRI study in 55 CUD patients (26 CUD-Crack and 29 CUD-Hydro) entering inpatient detoxification, and 38 matched healthy controls. In patients, a 3-months outpatient follow-up was carried out to specify the treatment outcome status (relapser when cocaine was consumed once or more during the past month). A Voxel-Based Morphometry approach was used. RESULTS: Compared with controls, CUD patients had widespread gray matter alterations, mostly in frontal and temporal cortices, but also in the cerebellum and several sub-cortical structures. We then compared CUD-Crack with CUD-Hydro patients and found that crack-cocaine use was associated with lower volume in the right inferior and middle temporal gyri, and the right fusiform gyrus. Cerebellar vermis was smaller during detoxification in subsequent relapsers compared to three-months abstainers. CONCLUSIONS: Patients with CUD display widespread cortical and subcortical brain shrinkage. Patients with preferential crack-cocaine use and subsequent relapsers showed specific gray matter volume deficits, suggesting that different patterns of cocaine use and different clinical outcome are associated with different brain macrostructure.

AIM OF THE STUDY: The past twenty years have seen a rise in cocaine-related statistics in France, including cocaine use in the general population, emergency ward presentations of acute cocaine intoxication, cocaine use disorders related outpatient appointments and cocaine-related deaths. This study's objectives were to describe trends in patients' admission for specific cocaine detoxification as well as changes in patients' characteristics in the Assistance publique-Hôpitaux de Paris (AP-HP) hospitals group located in Paris region, France. METHODS: We reviewed the international classification of diseases 10th edition (ICD-10) discharge codes of the AP-HP hospitals group between 2011 and 2021. In addition, medical reports of the largest addiction medicine ward were also analysed for changes across the years 2009, 2014, 2019 and 2022. RESULTS: The regional database showed an almost 3-fold increase in cocaine-related disorders discharge codes between 2011 and 2019. This occurred due to a rise in hospital stays for cocaine dependence or cocaine acute intoxication prior to the fall in levels of inpatient stays associated with the coronavirus disease 2019 (COVID-19) pandemic. The in-depth analysis of inpatients' stays in the specialized addiction medicine ward also showed an increase in admissions for cocaine detoxification programs, with a prevalence of 1.19% in 2009 to 15.73% in 2022 (P=1.44×10-20). Inpatient characteristics showed significant changes, especially in 2022, namely: more daily users, less intravenous administration and less comorbid illicit substances use disorders, with heightened levels of cured hepatitis C patients (P<0.05). Inpatient prescriptions were primarily dopaminergic antagonists with sedatives properties (cyamemazine, loxapine and chlorpromazine), dopamine-receptors partial agonist (aripiprazole) and serotonin reuptake inhibitors. CONCLUSION: The referral to hospital care for cocaine detoxification has increased in Paris region since 2011, coupled with changes in inpatients' characteristics. This trend has significant implications for the management of inpatient hospital services.
RESUMEN
Benzodiazepines (BZDs) are the first-line treatment of alcohol withdrawal. Comorbidity between benzodiazepine use disorder (BUD) and alcohol use disorders (AUD) is common. However, the risk factors are poorly characterized due to the paucity of available BUD screening tools. The present study aimed to rectify this by conducting an observational screening investigation for BUD in patients hospitalized for alcohol detoxification in a specialized unit. During a face-to-face interview, a short BUD screening tool, Echelle Cognitive d'Attachement aux benzodiazépines (ECAB), was administered to record recent patterns of BZD use, thereby allowing categorization of AUD patients as follows: non-BZD users, BZD users without BUD, and BUD (ECAB ≥6). Clinical and sociodemographic risk factors were identified and recorded during clinical assessment and were analyzed using nonparametric bivariate tests and multinomial regression for association with BUD, with p < 0.05 for significance. Of the 150 AUD patients, 23 (15%) had comorbid BUD. Several variables were associated with ECAB score, with their independence being verified using multinomial regression, with lower risk of BUD versus BZD use, when the initial prescriber was an addiction specialist compared with a psychiatrist or a general practitioner [odds ratio (OR) = 0.12, 95% confidence interval (CI) = 0.14-0.75]. A higher risk of BZD use versus no use was evident when comorbid psychiatric disorders were present (OR = 9.2, 95%CI = 1.3-65). Our findings raise clinicians' awareness that in patients hospitalized for alcohol detoxification, BUD is highly prevalent but not specifically related to psychiatric disorders. BUD can be effectively screened by utilization of the ECAB.

Alcohol use is a leading cause of mortality, brain morbidity, neurological complications and minor to major neurocognitive disorders. Alcohol-related neurocognitive disorders are consecutive to the direct effect of chronic and excessive alcohol use, but not only. Indeed, patients with severe alcohol use disorders (AUD) associated with pharmacological dependence suffer from repetitive events of alcohol withdrawal (AW). If those AW are not managed by adequate medical and pharmacological treatment, they may evolve into severe AW, or be complicated by epileptic seizure or delirium tremens (DT). In addition, we suggest that AW favors the occurrence of Wernicke's encephalopathy (WE) in patients with known or unknown thiamine depletion. We reviewed the literature on oxidative stress as a core mechanism in brain suffering linked with those conditions: AW, epileptic seizure, DT and WE. Thus, we propose perspectives to further develop research projects aiming at better identifying oxidative stress brain damage related to AW, assessing the effect of repetitive episodes of AW, and their long-term cognitive consequences. This research field should develop neuroprotective strategies during AW itself or during the periwithdrawal period. This could contribute to the prevention of severe alcohol-related brain damage and cognitive impairments.
RESUMEN
The disease progression of severe alcohol-related cognitive impairment (ARCI) is debated. The aim of this study was to compare the cognitive change of patients with severe ARCI in inpatient setting to that of patients with Alzheimer's disease (AD). Fifteen consecutive patients with severe ARCI were recruited between 2013 and 2015. They received inpatient detoxification, neurological assessment, and inpatient cognitive rehabilitation in specialized facilities. Twelve patients, with documented AD matched on sex and initial cognitive impairment severity, were selected. All have benefited from two neuropsychological assessments. The neurocognitive change was tested in both groups with pair-wised Wilcoxon tests. ARCI and AD patients' time course was compared with Mann-Whitney-Wilcoxon test. In ARCI group, first assessment occurred at 2.9 (± 2.2) months of abstinence and follow-up 6.5 (± 2.9) months later, the mean age was 56.5 (± 7.4) years, and 12 were men. In AD group, follow-up occurred at 12.8 (± 2.9) months (p < 10-3), the mean age was 72.3 (± 8.4) years (p < 10-3), and 10 were men. ARCI patients significantly improved on one executive function test (TMT-B; p < 0.05), while AD patients have worsened memory subtests on Free-and-Cued-Selective-Reminding Test (p < 0.05). These tests showed a statistically different change between severe ARCI and AD group (p < 0.05). Severe ARCI patients have improved in executive functioning, discernible on the TMT-B test, in specific care setting, including abstinence maintenance and rehabilitation. The disease progression was different from that observed in AD patients.
RESUMEN
Subjects with alcohol use disorder (AUD) display a high prevalence of cardiovascular risk factors (CRFs), and a high incidence of cardiovascular diseases associated with an earlier mortality. Abstinence has long-term cardiovascular and global health benefits. However, few studies have examined the short-term effect of alcohol cessation on cardiac function and key CRFs. The aim of the study was to assess brain natriuretic peptide (BNP) and other CRFs on admission for alcohol cessation and 12 days later, in inpatients with AUD. A retrospective chart review of inpatients hospitalized for alcohol cessation was conducted. Patients who did not relapse at day 12 were included. We compared, at entry and at day 12, BNP and other CRFs: hemodynamic and electromyographic variables, lipid, homocysteine level, and liver enzymes at entry and at day 12. Wilcoxon, Student tests, and repeated-measures ANOVA were conducted. Fifty-five patients were included (38 males, mean age 50.5 years, alcohol per day 60 g-750 g, 44 current tobacco smokers). BNP was significantly increased (11.8 pg/mL [±16.2] to 35.5 pg/mL [±47.6], p < 0.001). Repeated-measure ANOVA showed a significant between-subject effect (p = 0.024), but no significant interaction between BNP variation and having a BNP at entry >10 pg/mL (p = 0.092). In contrast, a significant improvement on 8 of 13 other CRFs and liver enzymes measures was observed (p ≤ 0.05). A rapid improvement of several CRFs was confirmed. However, the increase of BNP at day 12 supports its investigation as a possible relevant biomarker of cardiac function in alcohol withdrawal.

Introduction: Cocaine users often present with repetitive events of cocaine-associated chest pain (CACP), clinically resembling acute coronary syndromes. The aim of the study is to describe the specific risk factors for CACP. Method: Cocaine users (n = 316) were recruited for a multicenter cross-sectional study. Lifetime CACP history, sociodemographic factors, and lifetime use of cocaine and other substances were assessed. Thirty single nucleotide polymorphisms (SNPs) of NOS3, ROCK2, EDN1, GUCY1A3, and ALDH2 genes, suggested by the literature on coronary spasms, were selected. The associations with CACP history were tested using the chi-square test, Student's t-test and logistic regression. Results: Among the 316 subjects [78.5% men, mean age 37.5 years, (standard-deviation ±8.7)], 190 (60.1%) were daily cocaine users and 103 (32.6%) reported a lifetime CACP history. Among those with a lifetime CACP history, the median was 10 events per individual. In multivariate analysis, lifetime CACP history was associated with daily cocaine use [odds-ratio (OR) 3.24; 95% confidence intervals (1.29-9.33)], rapid route of cocaine use [OR 2.33 (1.20-4.64) vs. intranasal use], and lifetime amphetamine use [daily amphetamine use: OR 2.80 (1.25-6.32) and non-daily amphetamine use: OR 2.14 (1.15-4.04) vs. never used]. Patients with lifetime opioid maintenance treatment (OMT) reported significantly less lifetime CACP history [OR 0.35 (0.16-0.76)]. None of the selected SNPs was associated with CACP history after multiple testing corrections. Conclusions: Clinical variables describing the intensity of stimulant use were positively associated with lifetime CACP history, while OMT was negatively associated with it. Specific harm reduction strategies can target these risk factors.
RESUMEN
Malnutrition has been reported in alcohol use disorder patients as having a possible influence on cognitive function. The aim of this study was to analyse the prevalence of ascorbic acid (AA) deficiency in inpatients admitted for alcohol detoxification and the associated factors, including cognitive impairment in the early period of abstinence. A retrospective chart review was conducted. The AA level was categorised into three groups: deficiency (AAD) (<2 mg/L), insufficiency (AAI) (2-5 mg/L) and normal level. The cognitive impairment was screened using the Montreal Cognitive Assessment (MoCA). Ninety-six patients were included (74 men; mean age 49.1 years (±11.5)). Twenty-seven AAD (28.1%) and twenty-two AAI (22.9%) were observed. In multivariate analysis, risk factors for AAD versus normal AA level were men (OR 17.8, 95%CI (1.63-194)), compensated cirrhosis (OR 9.35, 95%CI (1.60-54.6)) and street homelessness (OR 5.76, 95%CI (1.24-26.8) versus personal housing). The MoCA score was available for 53 patients (mean MoCA score: 25.7 (±3.3)). In multivariate analysis, the natural logarithm of AA (ß = 1.18, p = 0.037) and sedative use disorder (ß = -2.77, p = 0.046) were associated with the MoCA score. AAD and AAI are frequent in inpatients admitted for alcohol detoxification. A low level of AA was associated with cognitive impairment in the early period of abstinence.
RESUMEN
Epidemiology of illicit substances use in france The landscape of illicit substances use is evolving in France, with dealers going digital. Cannabis and cocaine are consumed by 44% and 5% of French subjects, respectively, and are the most frequent motive for care. Other illicit substances such as ecstasy (MDMA), amphetamines, LSD and other hallucinogenic products are used by 2-3% of French subjects. Heroin and other opiates, although regularly used by less than 1% of French subjects, are provoking both a severe dependence and medical complications that require a specific treatment.
Épidémiologie des substances illicites en france Le paysage de l'usage des drogues illicites en France est mouvant, avec des modes d'approvisionnement et des réseaux de trafic qui se digitalisent. Le cannabis et la cocaïne ont déjà été consommés par 44 % et 5 % des Français respectivement, et sont à l'origine de la majorité des demandes de soins. D'autres substances sont consommées par 2-3 % des français, ce sont l'ecstasy (MDMA), les amphétamines, le LSD et les champignons hallucinogènes. L'héroïne et les autres opiacés, bien que consommés régulièrement par moins de 1 % des français, sont à l'origine d'une dépendance et de complications sévères dont le traitement est bien codifié.

This systematic review seeks to evaluate the efficacy of interventions aimed at preventing unintended pregnancies in women using psychoactive substances. Seven electronic databases (Medline, EMBASE, CINAHL, Web of Science Core Collection, PsycINFO, Cochrane CENTRAL database) were searched in October 2017. Twenty-two articles met our inclusion criteria. Interventions based on behavior change theory yielded an increase in the initiation of effective contraception as compared with provision of written information materials. The effect was more pronounced when the intervention provided on-site contraceptive counseling and free access to birth control. Financial incentives also seemed to effectively increase women's contraception intake. Case management interventions including pregnant and postpartum women with heavy levels of substance use showed promising results in terms of initiation of contraception, but rates of unintended pregnancy over long-term follow-up were nevertheless elevated. Finally, some interventions integrated family planning services into specialized centers taking care of pregnant and postpartum women with substance abuse. However, most studies aimed at postpartum and post-abortion contraception used a non-comparative design and had a number of methodological flaws. The risk of bias in most studies is high. All interventions with a primary or secondary focus on the prevention of unintended pregnancy in women using psychoactive substances short-term improvements in contraception intake, but it is unclear if these effects last or have any impact on unintended pregnancy rates in the long-term.
