Gamma irradiation-induced offspring masculinization is associated with epigenetic changes in female zebrafish.

Sex ratio variation is a key topic in ecology, because of its direct effects on population dynamics and thus, on animal conservation strategies. Among factors affecting sex ratio, types of sex determination systems have a central role, since some species could have a sex determined by genetic factors, environmental factors or a mix of those two. Yet, most studies on the factors affecting sex determination have focused on temperature or endocrine-disrupting chemicals (EDCs), and much less is known regarding other factors. Exposure to gamma irradiation was found to trigger offspring masculinization in zebrafish. Here we aimed at deciphering the potential mechanisms involved, by focusing on stress (i.e. cortisol) and epigenetic regulation of key genes involved in sex differentiation in fish. Cortisol levels in exposed and control (F0) zebrafish females' gonads were similar. However, irradiation increased the DNA methylation level of foxl2a and cyp19a1a in females of the F0 and F1 generation, respectively, while no effects were detected in testis. Overall, our results suggest that parental exposure could alter offspring sex ratio, at least in part by inducing methylation changes in ovaries.

[Addiction: what's new in 2023]. / Addictions: ce qui a changé en 2023.

Addiction medicine is currently facing new challenges, such as drug epidemics and open drug scenes. It is responding to these challenges with a range of innovations: 1. The commercialization of opioid-assisted treatment (OAT) is a major step forward. 2. In Geneva, a community outreach project involving mental health peer practitioners targets the emerging crack scene, demonstrating its effectiveness in directing this marginalized population towards care. 3. In Switzerland, two projects in French-speaking Switzerland are testing hybrid models of cannabis regulation. Evaluation of these projects will guide the best approach to cannabis regulation.

L'addictologie est actuellement confrontée à des nouveaux défis, tels que des épidémies de consommation et des scènes de drogues ouvertes. Elle répond à ces défis par différentes innovations. 1. La commercialisation du traitement assisté par opioïdes (TAO) en dépôt est une avancée majeure. 2. À Genève, un projet communautaire de maraudes, impliquant des pairs praticiens en santé mentale, cible la scène de consommation de crack émergente, montrant son efficacité pour orienter cette population marginalisée vers les soins. 3. En Suisse, deux projets romands testent des modèles hybrides de régulation du cannabis. L'évaluation de ces projets guidera la meilleure approche pour la régulation du cannabis.

Retinoic acid signaling within pancreatic endocrine progenitors regulates mouse and human ß cell specification.

Retinoic acid (RA) signaling is essential for multiple developmental processes, including appropriate pancreas formation from the foregut endoderm. RA is also required to generate pancreatic progenitors from human pluripotent stem cells. However, the role of RA signaling during endocrine specification has not been fully explored. In this study, we demonstrate that the disruption of RA signaling within the NEUROG3-expressing endocrine progenitor population impairs mouse ß cell differentiation and induces ectopic expression of crucial δ cell genes, including somatostatin. In addition, the inhibition of the RA pathway in hESC-derived pancreatic progenitors downstream of NEUROG3 induction impairs insulin expression. We further determine that RA-mediated regulation of endocrine cell differentiation occurs through Wnt pathway components. Together, these data demonstrate the importance of RA signaling in endocrine specification and identify conserved mechanisms by which RA signaling directs pancreatic endocrine cell fate.

Safety and feasibility of intranasal heroin-assisted treatment: 4-week preliminary findings from a Swiss multicentre observational study.

BACKGROUND: Heroin-assisted treatment (HAT) is effective for individuals with severe opioid use disorder (OUD) who do not respond sufficiently to other opioid agonist treatments. It is mostly offered with injectable diacetylmorphine (DAM) or DAM tablets creating a barrier for individuals who need the rapid onset of action but are either unable or unwilling to inject, or primarily snort opioids. To explore another route of administration, we evaluated the safety and feasibility of intranasal (IN) DAM. METHODS: This is a multicentre observational cohort study among patients in Swiss HAT. All patients planning to receive IN DAM within the treatment centres were eligible to participate. Participants were either completely switched to IN DAM or received IN DAM in addition to other DAM formulations or opioid agonists. Patients were followed up for four weeks. Sociodemographic characteristics, current HAT regimen, reasons for starting IN DAM, IN DAM doses, number of injection events in the sample, IN DAM continuation rate, and appearance of adverse events and nose-related problems were evaluated. RESULTS: Participants (n = 52) reported vein damage, preference for nasal route of administration, and desire of a stronger effect or for a less harmful route of administration as primary reasons for switching to IN DAM. After four weeks, 90.4% of participants (n = 47) still received IN DAM. Weekly average realised injection events decreased by 44.4% from the month before IN DAM initiation to the month following. No severe adverse events were reported. CONCLUSIONS: After four weeks, IN DAM was a feasible and safe alternative to other routes of administration for patients with severe OUD in HAT. It addressed the needs of individuals with OUD and reduced injection behaviour. More long-term research efforts are needed to systematically assess efficacy of and patient satisfaction with IN DAM.

[Benzodiazepines and elderly : challenges of prescribing and deprescribing]. / Benzodiazépines et âge avancé : défis de la prescription et de la déprescription.

The elderly represent a group at risk of receiving problematic benzodiazepine (BZD) prescriptions in terms of duration or dose. The objective of this article is to investigate the difficulties related to the initial prescription, renewal, and withdrawal of BZDs in two university hospitals in French-speaking Switzerland. Specifically, we studied the actual use and perceived usefulness of clinical guidelines, the assignment of responsibilities among prescribers, and the assessment of public health risks. Eight semi-structured interviews were conducted with professionals from different specialties. A lack of usable clinical recommendations was noted, attributable to the lack of scientific knowledge and the complexity of geriatric cases. The introduction and renewal of prescriptions should be the result of systematic consultations between hospitals and ambulatory care.

Les personnes d'âge avancé représentent un groupe à risque de recevoir des prescriptions de benzodiazépines (BZD) problématiques en termes de durée ou de dose. L'objectif de cet article est d'investiguer les défis liés à la primo-prescription, la reconduction et le sevrage des BZD dans deux hôpitaux universitaires romands. Spécifiquement, nous avons étudié l'usage effectif et l'utilité perçue des recommandations cliniques, la répartition des responsabilités parmi les personnes qui prescrivent et l'appréciation des risques pour la santé publique. Huit entretiens semi-structurés ont été menés avec des professionnel-le-s de différentes spécialités hospitalières. Il est noté un manque de recommandations cliniques exploitables, s'expliquant par l'absence de connaissances scientifiques et par la complexité des cas gériatriques. L'introduction et la reconduction des prescriptions devraient faire l'objet de concertations systématiques entre les soins en hospitalier et en ambulatoire.

[Assisted suicide: a need for clarification]. / Suicide assisté : un besoin de clarification.

In Switzerland, altruistic assisted suicide is permitted. We present here the federal regulations, the deontological rules, the provisions adopted by the cantons and other requirements applicable to assisted suicide. Given the complexity of these different rules and the legal questions that remain open, we recommend the preparation of brochures for patients, as well as better training and support for people faced with requests for assisted suicide.

En Suisse, l'assistance altruiste au suicide est admise. Nous présentons ici la règlementation fédérale, les règles déontologiques, les dispositions adoptées par les cantons et les éventuelles autres exigences applicables en matière de suicide assisté. Vu la complexité de ces différentes règles et les questions juridiques encore ouvertes, nous recommandons la rédaction de brochures à destination des patients, ainsi qu'une meilleure formation et encadrement des personnes confrontées à des demandes d'assistance au suicide.

[Therapeutic contracts and opioid agonist treatments: legally and ethically questionable]. / Contrats thérapeutiques et traitements agonistes opioïdes : juridiquement et éthiquement discutables.

In Switzerland, the use of « therapeutic contracts ¼ in the implementation of opioid agonist treatments (OAT) is frequently recommended or even imposed. These documents raise legal and ethical issues, which are presented in this article. The authors recommend that this practice be abandoned. The usual tools of medical treatments (e.g. information document, treatment plan) are sufficient.

En Suisse, l'usage de « contrats thérapeutiques ¼ dans le cadre de la mise en œuvre des traitements agonistes opioïdes (TAO) est fréquemment recommandé, voire imposé. Ces documents soulèvent des problèmes juridiques et éthiques, présentés dans cet article. Les auteurs recommandent l'abandon de cette pratique. Les outils ordinaires de la prise en charge médicale (par exemple, document d'information, plan de traitement) suffisent.

[Drugs: minors and harm reduction?] / Drogues : mineur-e-s et réduction des risques ?

The use of controlled substances (narcotics and psychotropic substances) poses increased risks for minors. However, minors are generally excluded from existing harm reduction services (e.g. drug consumption rooms, drug checking, exchange of consumption material). Based on public health considerations, the authors recommend the establishment of harm reduction services for minors.

La consommation de substances soumises à contrôle (stupéfiants et substances psychotropes) présente des risques accrus pour les mineur-e-s. Pourtant, ces derniers sont généralement exclus des offres existantes de réduction des risques et des méfaits (par exemple, locaux de consommation, drug checking, échange de matériel de consommation). Sur la base de considérations de santé publique, les auteurs recommandent la création de services de réduction des risques dédiés aux mineur-e-s.

[Addiction: what's new in 2022]. / Addictions : ce qui a changé en 2022.

Addictions appear everywhere, mutate, transform with new products and behaviors, playing on our painstaking efforts to try to control them. Drawn into this current, the impression that dominates invites more to understand and to coax rather than to fight. Addictions are our condition, let's deal with it, rather than fight against them. It is therefore a question of knowing the products, that everyone can identify their level of risk, and of giving as many tools as possible, at any age, whatever the behavior or the product. This article shows us that there is a lot to do, from school benches to liver transplantation. There is also a lot to discover, in the recognition of the therapeutic virtues, of cannabinoids for example or even in their prescription, of pharmaceutical heroin for example, sometimes by far the best option.

Les addictions émergent de partout, mutent, se transforment avec des nouveaux produits et comportements, se jouant de nos efforts laborieux pour tenter de les contrôler. Entraînés dans ce courant, l'impression qui domine invite davantage à comprendre et à amadouer plutôt qu'à lutter. Les addictions sont notre condition, faisons avec, plutôt que contre. Il s'agit donc de connaître les produits, que chacun puisse identifier son niveau de risque, et de donner autant d'outils que possible, à tout âge, quel que soit le comportement ou le produit. Cet article nous montre qu'il y a beaucoup à faire, des bancs de l'école à la transplantation hépatique. Il y a aussi beaucoup à découvrir, dans la reconnaissance des vertus thérapeutiques, des cannabinoïdes par exemple, ou encore dans leur prescription, de l'héroïne pharmaceutique, parfois de loin la meilleure option.

Profiling Parkinson's disease cognitive phenotypes via resting-state magnetoencephalography.

Aberrant brain oscillations are a hallmark of Parkinson's disease (PD) pathophysiology and may be related to both motor and nonmotor symptoms. Mild cognitive impairment (MCI) affects many people with PD even at the time of diagnosis and conversion risks to PD dementia (PDD) are very high. Unfortunately, pharmacotherapies are not addressing cognitive symptoms in PD. Profiling PD cognitive phenotypes (e.g., MCI, PDD, etc.) may therefore help inform future treatments. Neurophysiological methods, such as magnetoencephalography (MEG), offer the advantage of observing oscillatory patterns, whose regional and temporal profiles may elucidate how cognitive changes relate to neural mechanisms. We conducted a resting-state MEG cross-sectional study of 89 persons with PD stratified into three phenotypic groups: normal cognition, MCI, and PDD, to identify brain regions and frequencies most associated with each cognitive profile. In addition, a neuropsychological battery was administered to assess each domain of cognition. Our data showed higher power in lower frequency bands (delta and theta) observed along with more severe cognitive impairment and associated with memory, language, attention, and global cognition. Of the total 119 brain parcels assessed during source analysis, widespread group differences were found in the beta band, with significant changes mostly occurring between the normal cognition and MCI groups. Moreover, bilateral frontal and left-hemispheric regions were particularly affected in the other frequencies as cognitive decline becomes more pronounced. Our results suggest that MCI and PDD may be qualitatively distinct cognitive phenotypes, and most dramatic changes seem to have happened when the PD brain shows mild cognitive decline.NEW & NOTEWORTHY Can we better stage cognitive decline in patients with Parkinson's disease (PD)? Here, we provide evidence that mild cognitive impairment, rather than being simply a milder form of dementia, may be a qualitatively distinct phase in its development. We suggest that the most dramatic neurophysiological changes may occur during the time the PD brain transitions from normal cognition to MCI, then compensatory changes further occur as the brain "switches" to a dementia state.

Offline and Online Gambling in a Swiss Emerging-Adult Male Population.

Faced with the rapid expansion of the online gambling offer, a growing number of jurisdictions around the world are developing legislation to regulate online gambling. The new Swiss Act on gambling extends legalization of online gambling from already authorized lottery-type to casino-type gambling. In this context, the present study examines offline and online gambling behaviors in emerging-adult males as a particularly at-risk population for gambling addiction. A sample of 1,869 young males completed a questionnaire assessing offline and online gambling behaviors as well as severity of problem gambling. Results show that 62.1% of the respondents were lifetime gamblers while 46.7% were past-year gamblers. Among the latter, 76.4% had gambled only within offline venues, 21.4% had gambled at both offline and online sites, and 2.2% had gambled online only. Furthermore, 17.6% of past-year gamblers were at moderate-risk of developing problem gambling whilst 3.6% were problem gamblers. Association analysis showed that, compared to non-problem gamblers, at-risk and problem gamblers played online at higher rates. These findings contribute to the growing literature on youth gambling behaviors and on offline-online transitions. In the context of the growing online gambling supply, the evolution of youth gambling behaviors should be monitored through periodical assessments.

Prescribing medicines containing controlled substances (SSC : narcotics and psychotropic substances) can have legal consequences as per the Road Traffic Act. We set forth the physician's duties as well as the risks incurred by the patient. We recommend that rules regarding SSC, which can influence the capacity or the ability to drive, be clarified.

Prescrire des médicaments contenant des substances soumises à contrôle (SSC : stupéfiants et substances psychotropes) peut avoir des conséquences en matière de circulation routière.

[What's new in addiction medicine in 2021 ?] / Addictions.

Addiction medicine is influenced by societal changes and the environment has an impact on addictive behaviors and how they are experienced. The COVID-19 pandemic has had an impact on addictive behaviors, some of which could be favorable, and others highlight vulnerabilities to be considered by clinicians. Recent legislative changes open possibilities to limit the negative impact of electronic lotteries. In a context favorable to a better acceptance of people of LGBTQIA+ diversity, research and training in addiction medicine also have a role to play. In view of advances in understanding the harmful effects of alcohol, it is necessary to adapt the perception of the risk, in order not to provoke the incomprehension in the population.

La médecine des addictions est liée aux enjeux sociétaux actuels, et l'environnement joue un rôle important sur les comportements addictifs et comment ils sont vécus. La pandémie de Covid-19 a eu un impact sur les comportements addictifs, dont certains pourraient être positifs et d'autres mettent en lumière des vulnérabilités à prendre en compte en clinique. Les récents changements législatifs ouvrent des possibilités pour limiter l'impact négatif des loteries électroniques. Dans le contexte favorable à une meilleure acceptation des personnes issues de la diversité LGBTQIA+ (lesbienne, gay, bisexuel·le, transgenre, queer, intersexe et asexuel·le ou aromantique), la recherche et la formation en médecine des addictions ont aussi un rôle à jouer. Au vu des avancées dans la connaissance des effets nocifs de l'alcool, il est nécessaire d'adapter la perception du risque, afin de ne pas susciter l'incompréhension de la population.

Spasticity in practice (SPACE): an international non-interventional study of botulinum neurotoxin type A in treatment-naïve subjects with spasticity.

AIM OF THE STUDY: SPACE, a prospective, non-interventional, open-label, multinational study, investigated physicians' and subjects' assessment of safety, efficacy, and health-related quality of life (HRQoL) following botulinum neurotoxin type A (BoNT-A) treatment to understand real-world clinical usage for the management of focal and multifocal spasticity. CLINICAL RATIONALE FOR THE STUDY: Treatment guidelines recommend the use of BoNT-A for the management of spasticity in adults. This study assessed how physicians use BoNT-A therapy in real-world clinical practice, and provided evidence on long-term safety and efficacy over a period of up to 2 years. MATERIALS AND METHODS: BoNT treatment-naïve adults with spasticity of any aetiology received any BoNT-A formulation at their physician's discretion, and were observed for ≤ 8 treatment cycles (≤ 2 years). Daily practice information, physician's global assessments of tolerability and efficacy, and HRQoL were documented. Incidences of adverse drug reactions or all adverse events were documented for non-Mexican subjects and for Mexican subjects, respectively, due to protocol differences based on local regulatory requirements. RESULTS: A total of 701 subjects were enrolled (safety population; nine countries). Physicians rated the tolerability of BoNT-A as 'very good' or 'good' for 88.2-97.4% of subjects throughout the study (subject numbers declined throughout this non-interventional study). Adverse drug reactions were reported for 16/600 (2.7%) of the non-Mexican subjects, with two considered to be 'definitely related' to treatment (injection-site haematoma, n = 1; botulism, n = 1). For 687 subjects, efficacy was rated 'very good' or 'good' by most physicians and subjects. Improvements in HRQoL were observed. CONCLUSIONS AND CLINICAL IMPLICATIONS: Throughout this 2-year study, BoNT-A treatment was generally well-tolerated, effective, and associated with an improved HRQoL. This study makes a valuable contribution to the broader understanding of how physicians use BoNT-A therapy to manage spasticity in real-world clinical practice.

[Benzodiazepines, addiction and cantonal authorization : legal framework and clinical implications.] / Benzodiazépines, addiction et autorisation cantonale : cadre juridique et implications cliniques.

Use of benzodiazepine and Z-drug is common in Switzerland, also for prolonged periods of time. Physical dependence, psychological dependence and a syndrome of dependence may ensue. Related to a lack of well-established medical guidelines, current clinical practices are subject to debate. Also controversial is the need to request an authorization from the cantonal health authorities before starting treatment with these controlled substances. The present article describes the limited circumstances in which such prior authorization is required.

La prescription de benzodiazépines et de Z-drugs (zolpidem, zopiclone, zaléplone) est fréquente en Suisse, y compris en traitement de longue durée. Il peut s'ensuivre une dépendance physique ou psychologique, et plus rarement un syndrome de dépendance. En l'absence de directives reposant sur des évidences scientifiques consolidées, les pratiques effectives des professionnels de la santé sont sujettes à débat. L'est également l'obligation d'obtenir une autorisation cantonale préalable à la mise en place d'un traitement contenant ces substances soumises à contrôle. Le présent article décrit les conditions dans lesquelles une telle autorisation est requise ou non.

[What's new in addiction medicine]. / Addictions.

The development of research, clinical practice and prevention in addiction medicine is, compared to other disciplines, more influenced by socio-political factors. Research on psychedelics has thus long been hampered by prohibitive policy but has recently been revived thanks to the relaxation of these political positions. The extensive prescription of baclofen for alcohol addiction is mainly the consequence of popular support and has so far not been clearly supported by specific research. The aim of the new Gambling Act was to harmonize the regulatory provisions for lotteries and betting on the one hand and casino gambling on the other, while at the same time opening up the market for online gambling.

Le développement de la recherche, de la pratique clinique et de la prévention en addictologie est davantage influencé par les circonstances sociopolitiques que dans de nombreuses autres disciplines. La recherche sur les psychédéliques a ainsi longtemps été entravée par une politique prohibitive mais a été relancée récemment grâce à l'assouplissement de ces positions politiques. La prescription importante du baclofène pour traiter l'addiction à l'alcool est principalement la conséquence d'un soutien populaire et n'est jusqu'à présent pas clairement appuyée par la recherche spécifique. Le but de la nouvelle loi sur les jeux d'argent était d'harmoniser les dispositifs de régulation concernant les loteries et paris d'une part et les jeux de casinos d'autre part, tout en ouvrant le marché des jeux en ligne.

Quality of life in subjects with upper- and lower-limb spasticity treated with incobotulinumtoxinA.

BACKGROUND: We evaluated quality of life among subjects with upper- and lower-limb spasticity who received escalating doses of incobotulinumtoxinA (total body doses up to 800 U) in the prospective, single-arm, dose-titration TOWER study. METHODS: In this exploratory trial, subjects (N = 155; 18-80 years of age) with upper- and lower-limb spasticity due to cerebral causes who were deemed to require total body doses of up to 800 U incobotulinumtoxinA received three consecutive injection cycles of incobotulinumtoxinA (400, 600, and up to 800 U), each with 12 to 16 weeks' follow-up. QoL was assessed using the EuroQol 5-dimensions questionnaire, three-level (EQ-5D), before and 4 weeks post-injection in each injection cycle and at the end of injection cycle 3. RESULTS: The mean EQ-5D visual analog scale scores of 155 participants continuously improved from study baseline to 4 weeks post-injection in all injection cycles (mean [standard deviation] change 6.7 [14.1], 9.6 [16.3], and 8.6 [17.0] for injection cycles 1, 2, and 3, respectively; p < 0.0001 for all, paired sample t-test). In general, among those with a change in the EQ-5D rating of their condition, the proportion of subjects with 'improvement' was greater than that with 'worsening' for individual EQ-5D dimensions across all injection cycles. At the end of injection cycle 3, the proportion of subjects rating their condition as 'normal' increased from study baseline for all dimensions, and there was a ≥ 46% reduction in the proportion of subjects with a rating of 'severe impairment'. CONCLUSION: These preliminary results suggest that escalating incobotulinumtoxinA doses up to 800 U are associated with improvement in quality of life ratings in subjects with multifocal upper- and lower-limb spasticity, and form a basis for future comparator studies.

Independent risk factors for ICU mortality after left ventricular assist device implantation.

Left ventricular assist devices (LVADs) are used as an alternative therapy for heart transplantation in patients with advanced heart failure. However, the mortality rate of these patients remains relatively high. A large proportion of deaths after LVAD implantation occur during intensive care unit (ICU) stay. We conducted a retrospective study to identify the risk factors for all-cause ICU mortality in patients with an implanted LVAD. Between January 1, 2008 and December 31, 2016, 70 consecutive patients who had received an LVAD were analyzed. The median ICU length of stay was 14 days (IQR: 8-31) and 16 patients (22.9% [95%CI: 13.1-32.7]) died in the ICU. The 90-day mortality rate was 25.7% (95%CI: 15.5-35.9). The main causes of ICU mortality were: multiple organ failure, stroke, and hemorrhagic events. The univariate analysis identified the following perioperative risk factors for all-cause ICU mortality: hypertension, preoperative platelet count, preoperative white cell count, inotropic support before LVAD implantation, mechanical ventilation before LVAD implantation, renal replacement therapy before LVAD implantation, short-term mechanical support before LVAD implantation, INTERMACS class 1 to 2, low intraoperative platelet count, low early postoperative hemoglobin level, low early postoperative platelet count, low early postoperative pH, and massive perioperative blood transfusion. In the multivariate logistic regression analysis, only mechanical ventilation before LVAD implantation was retained as an independent risk factor for ICU mortality (OR = 11.96 [95%CI: 2.67-53.45], P < .01). These findings confirm that most deaths after LVAD implantation occur in the ICU. Patients that receive mechanical ventilation preoperatively have the highest risk of death. This confirms the need to actively treat respiratory failure and to wean patients from respiratory support before LVAD implantation. Such a strategy offers the best opportunity to initiate active rehabilitation.

This article describes a new form of administration of inhaled prescribed heroin currently under investigation. It underlines the particularity of opioid agonist prescription in jail and presents new perspectives in using psilocybin in addiction medicine treatment. A brief literature review about vaping confirms its interest in quitting cigarette, with a cost of addiction to vaping and recent worrisome reports of chemical pneumonia. Finally, the withdrawal of WHO guidelines on opiates use in pain management, in the context of a suspicion of conflict of interest, underlines the sensible balance between over- and under- prescription of opiates in analgesic treatment.

Cet article montre l'intérêt d'une nouvelle forme d'administration inhalée d'héroïne pharmaceutique actuellement à l'étude. Il sensibilise aux conditions particulières de la prescription d'agonistes opioïdes en milieu carcéral et ressuscite des souvenirs des seventies en reprenant l'exploration scientifique des vertus thérapeutiques de la psilocybine. Même si le vapotage semble être un bon moyen de lâcher la cigarette, les anciens fumeurs ont tendance à s'y accrocher et un risque de pneumonie chimique parfois mortelle vient d'être mis en évidence. Finalement, le retrait de l'OMS de deux directives relatives à l'usage d'opioïdes dans le traitement de la douleur, sur fond de suspicion de conflit d'intérêts, montre l'équilibre délicat entre sur- et sous-prescription des antalgiques opioïdes.

[Use of clear and nonstigmatizing language is necessary in addiction medicine]. / L'emploi d'un langage non stigmatisant et précis est nécessaire en médecine des addictions.

The language used has an impact on clinician attitudes and behaviors. In particular, the use of stigmatizing language or language reducing individuals in treatment to a given behavior has a negative impact on clinician attitudes, perception of people, perception of the disorders and treatment options. In addiction medicine, using clear, non-stigmatizing and scientifically appropriate language aims at delivering better care, increases treatment access, improves communication between health care professionals and improves knowledge transfer towards health care system users and their families, health care providers and society. The use of clear, slang-free, people-first language is crucial.

Le langage influence les attitudes et le comportement des clinicien·ne·s. Notamment l'emploi d'un langage stigmatisant et amalgamant les personnes en traitement et leur comportement a une influence négative sur les attitudes des clinicien·ne·s, leur perception des personnes, des troubles et des soins proposés. En médecine des addictions, employer un langage non stigmatisant, précis et scientifiquement approprié vise à améliorer la prise en charge et l'entrée en soins ainsi que la communication entre professionnel·le·s, diffuser les connaissances actuelles auprès des usager·ère·s du système de soins et de leur entourage, des professionnel·le·s de la santé et de la société en général. L'utilisation d'un langage centré sur la personne, précis, non argotique est crucial.
