Assistência pré-natal às usuárias de substâncias psicoativas: dificuldades elencadas pelos profissionais da saúde / Prenatal care for users of psychoactive substances: difficulties listed by health professionals / Atención prenatal a consumidoras de sustancias psicoactivas: dificultades mencionadas por los profesionales de la salud

Objetivo: conhecer as dificuldades elencadas pelos profissionais de saúde na assistência pré-natal às usuárias de substâncias psicoativas. Método: estudo qualitativo, exploratório-descritivo, realizado nas mídias sociais, com profissionais da área da saúde que realizam atendimento pré-natal. A coleta de dados ocorreu de novembro de 2022 a janeiro de 2023 por meio de questionário eletrônico. Os dados foram analisados por meio da análise temática. Protocolo aprovado pelo Comitê de Ética em Pesquisa. Resultados: os profissionais destacam o déficit de conhecimento para abordar este público em específico. A abordagem superficial e condenatória do uso de substâncias pelas políticas públicas corrobora para que os profissionais se sintam preparados em parte para atender essas gestantes. Considerações finais: a capacitação dos profissionais é necessária para superar práticas condenatórias e retrógradas de cuidado que focam unicamente a abstinência; como também, o investimento na capacitação acerca da rede de atenção à saúde, buscando ampliar sua visibilidade e utilização.

Objective: understanding the difficulties listed by health professionals in prenatal care for users of psychoactive substances. Method: this is a qualitative, exploratory-descriptive study carried out on social media with health professionals who provide prenatal care. Data was collected from November 2022 to January 2023 using an electronic questionnaire. The data was analyzed using thematic analysis. Protocol approved by the Research Ethics Committee. Results: the professionals highlight the lack of knowledge to deal with this specific public. The superficial and condemnatory approach to substance use by public policies contributes to making professionals feel partly prepared to deal with these pregnant women. Final considerations: the training of professionals is necessary to overcome condemnatory and retrograde care practices that focus solely on abstinence; and investment in training about the health care network, seeking to increase its visibility and use.

Assessing Consistency of Respondent-driven Sampling Estimators by Using Repeated Surveys among People Who Inject Drugs (PWID) in New Jersey.

Respondent-driven sampling (RDS) is widely used to sample populations with higher risk of HIV infection for whom no sampling frames exist. However, few studies have been done to assess the consistency of RDS estimators in real world settings. We conducted an assessment study on the consistency of RDS estimators using data from the National HIV Behavioral Surveillance - People Who Inject Drugs surveys in Newark, New Jersey from 2005 to 2018. Population parameter estimates based on RDS-I, RDS-II, Gile's SS, and HCG were compared longitudinally and cross-sectionally. Population homophily statistics and differential recruitment statistics were estimated and compared. Convergence plots were used for RDS diagnosis. Sensitivity analyses were conducted on population size estimates and seeds biases. By comparing time-insensitive population parameters and population homophily statistics estimated by four RDS estimators, the study found that RDS-II and Gile's SS could provide longitudinally and cross-sectionally consistent estimates and population homophily statistics on gender and sexual orientation. Cross-sectional comparison of time-sensitive population parameter estimates also supported the consistency of RDS-II and Gile's SS. However, RDS-I and HCG did not perform well in those comparisons. In conclusion, RDS estimators may not address all inconsistencies, but RDS-II and Gile's SS are recommended to weight RDS samples given enough consistency was observed in them.

Diagnostic Overshadowing of Chronic Hepatitis C in People With Mental Health Conditions Who Inject Drugs: A Scoping Review.

Diagnostic overshadowing refers to a phenomenon whereby people with mental health conditions encounter inadequate or delayed medical attention and misdiagnosis. This occurs when physical symptoms are mistakenly attributed to their mental health condition. This paper presents a scoping review focusing on direct causes and background factors of diagnostic overshadowing in the context of hepatitis C infection in people who inject drugs and have concurrent mental health conditions. Despite significant strides in hepatitis C treatment with direct-acting antiviral drugs, the complex interplay of mental health conditions and physical symptoms necessitates a nuanced approach for accurate diagnosis and effective screening. This review was conducted using Joanna Briggs Institute's methodology for scoping reviews. The databases searched included Medline, Embase, PsycInfo, Global Health, CINAHL and Scopus. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). The search strategies identified 1995 records. Overall, 166 studies were excluded. Forty-two (42) studies met the inclusion criteria. Three (n = 3) studies represented direct causes, and 39 (n = 39) with background factors related to diagnostic overshadowing. Studies highlighted six key themes encompassing diagnostic overshadowing, with communication barriers, stigma and knowledge deficiencies being the most prominent. Recognising and addressing diagnostic overshadowing in chronic hepatitis C will lead to increased screening, diagnosis and timely administration of life-saving antiviral therapy, resulting in profound enhancements in well-being and health outcomes. Moreover, this proactive approach will play a pivotal role in advancing the global effort towards eliminating hepatitis C by 2030.

Serological Screening and Risk Factors Associated with Leishmania infantum Positivity in Newly Diagnosed HIV Patients in Greece.

A serological screening was conducted to detect IgG antibodies against Leishmania infantum (L. infantum) in newly diagnosed human immunodeficiency virus (HIV) patients in Greece. The study also examined potential risk factors and the agreement of commercially available serological methods. IgG antibodies against L. infantum were detected using enzyme-linked immunosorbent assay (ELISA), indirect immunofluorescence antibody test (IFAT), and Western blot (WB). Out of 155 samples, 14 (9.0%) tested positive for IgG antibodies against L. infantum using at least two methods. Statistical analysis showed substantial agreement between WB and IFAT methods (Cohen's kappa = 0.75) but moderate overall agreement among the three methods (Fleiss' kappa = 0.42). Additionally, HIV+ intravenous drug users faced 3.55 times (p = 0.025) higher risk of testing positive for L. infantum IgG, positing that anthroponotic transmission between these patients is a plausible hypothesis based on existing literature. Non-invasive and cost-effective techniques are preferred to detect asymptomatic infections, and leishmaniasis screening should be conducted immediately after HIV diagnosis in endemic regions to enable prophylactic treatment for leishmaniasis in addition to antiretroviral therapy. To maximize sensitivity, performing at least two different serological methods for each patient is recommended.

Explaining child maltreatment and aggression among Chinese drug user: The mediating and moderating roles of drug craving and impulsivity.

BACKGROUND: The cycle of violence highlights a strong correlation between child maltreatment and aggression. However, there remains a significant gap in the pathway models of the cycle of violence. Given the exceptionally high rates of child maltreatment and violent crime among Chinese drug users, it is essential to examine the mechanisms of the cycle of violence within this group. OBJECTIVE: The current study incorporates drug craving and impulsivity into the child maltreatment-aggression mechanism. We explore the potential mediating and moderating roles of these variables and further examine the heterogeneity. PARTICIPANTS AND SETTING: A total of 894 participants (Meanage = 38.30, SDage = 8.38) were recruited as the final sample. METHODS: We employed moderated mediation and serial mediation models to explore the roles of drug craving and impulsivity. The Johnson-Neyman method was utilized to investigate moderating effects. Rich demographic variables and depression were controlled. RESULTS: There was no direct relationship between child maltreatment and aggression. The moderated mediation model indicated that drug craving played a mediating role, and there was a substitutive relationship between impulsivity and drug craving. The serial mediation model showed that child maltreatment could only affect drug craving (not impulsivity) and could ultimately influence aggression through a chain relationship. Heterogeneity tests revealed that the mechanisms might differ among various types of maltreatment. CONCLUSION: Drug craving holds a significant position in the cycle of violence. Compared to impulsivity, it is a more proximal factor to child mistreatment. Future research should also focus on the heterogeneity of child maltreatment for targeted interventions.

Opioid-related deaths in Northern Ontario in the early COVID-19 pandemic period.

OBJECTIVES: In the first year of pandemic measures, opioid-related deaths across Ontario's (ON) 34 public health units (PHUs) increased by 60%. Death rates for all seven Northern ON PHUs were above the provincial average. This study describes and compares factors surrounding opioid-related deaths before and after pandemic measures were introduced, for Northern ON compared to the rest of ON. METHODS: Aggregate data were provided for Northern ON and the rest of the province by the Office of the Chief Coroner/Ontario Forensic Pathology Services. Opioid-related deaths were cohorted by date of death for the year before and after pandemic measures were introduced on March 16, 2020. Chi-square tests were used to compare between cohorts and geographies to determine significant differences for each variable, and for dichotomized levels within variables. P-values < 0.05 were considered statistically significant a priori. RESULTS: In Northern ON, the number of opioid-related deaths approximately doubled from the pre-pandemic cohort (n = 185) to the early pandemic cohort (n = 365). Compared to the rest of ON, higher proportions of deaths occurred in Northern ON among individuals who lived and died in private residences, among women (although the majority of decedents were male) and among individuals employed in mining, quarrying, and oil and gas industries. Compared to the pre-pandemic year, in Northern ON, higher proportions of opioid-related deaths involved fentanyl and stimulants as direct contributors, and the majority involved evidence of inhaled drugs. CONCLUSION: Differences between the circumstances of death in Northern ON and in the rest of ON suggest opportunities to tailor interventions.

RéSUMé: OBJECTIFS: Au cours de la première année des mesures de lutte contre la pandémie, les décès liés aux opioïdes dans les 34 bureaux de santé publique (BSP) de l'Ontario ont augmenté de 60 %. Les taux de mortalité dans les sept unités de santé publique du Nord de l'Ontario étaient plus élevés de la moyenne provinciale. Cette étude décrit et compare les facteurs entourant les décès liés aux opioïdes avant et après l'introduction des mesures de lutte contre la pandémie, dans le Nord de l'Ontario par rapport au reste de la province. MéTHODES: Les données pour le Nord de l'Ontario et le reste de la province ont été fournies par le Bureau du coroner en chef/Service de médecine légale de l'Ontario. Les décès liés aux opioïdes ont été classés par date de décès pour l'année précédant et suivant l'introduction des mesures de lutte contre la pandémie le 16 mars 2020. Des tests du khi carré ont été utilisés pour comparer les cohortes et les zones géographiques afin de déterminer les différences significatives pour chaque variable et pour les niveaux dichotomisés au sein des variables. Les valeurs p < 0,05 ont été considérées statistiquement significatives. RéSULTATS: Dans le Nord de l'Ontario, le nombre de décès liés aux opioïdes a approximativement doublé entre la cohorte prépandémique (n=185) et la cohorte du début de la pandémie (n=365). Comparativement au reste de l'Ontario, des proportions plus élevées de décès sont survenus dans le Nord de l'Ontario chez les personnes qui vivaient et sont décédées dans des résidences privées, chez les femmes (bien que la majorité des personnes décédées étaient des hommes) et chez les personnes employées dans les mines, les carrières et les industries pétrolières et gazières. Comparativement à l'année prépandémique, dans le Nord de l'Ontario, des proportions plus élevées de décès liés aux opioïdes impliquaient le fentanyl et les stimulants comme contributeurs directs, et la majorité d'entre eux impliquaient des preuves de drogues inhalées. CONCLUSION: Les différences entre les circonstances des décès dans le Nord de l'Ontario et dans le reste de la province suggèrent des possibilités d'adapter les interventions.

Nursing interventions in patients with substance use disorders. A systematic review.

OBJECTIVE: To analyze the current available evidence on non-pharmacological interventions for increasing the withdrawal of patients with substance use disorder. METHOD: A systematic review of randomized clinical trials with a control group has been carried out where a non-pharmacological intervention is carried out in which nurses participate. The search was carried out in Pubmed, Cinahl, Web of Science, Scopus and Cochrane. randomized clinical trials with a control group published between 2018 and 2023 were selected. RESULTS: 15 articles were selected. A longer abstinence time was observed in the interventions that proposed a personalized telematic follow-up with a health worker, the establishment of the figure of the care coordinator or financial rewards based on the abstinence time. No significant differences regarding abstinence were observed in the formative interventions or with relaxation techniques only. However, relaxation techniques combined with other interventions could be effective. CONCLUSIONS: The identified interventions can be incorporated into nursing practice. They present encouraging results, although it would be advisable to study their long-term effectiveness.

Primary healthcare professionals' attitudes toward patients with current or previous drug use.

OBJECTIVE: People with current or previous drug use (PCPDU) often lack long-term healthcare contacts in primary healthcare (PHC). While international research has shown negative attitudes toward PCPDU in healthcare, PHC professionals' attitudes toward PCPDU have not been assessed in Sweden. The aim of this study was to investigate PHC professionals' attitudes to PCPDU, and to compare attitudes toward people who actively use illicit drugs with those toward patients in opioid assisted treatment (OAT). DESIGN: In this survey study, respondents were asked for background data, and their attitudes toward patients using illicit drugs, OAT patients and patients with depression were assessed by using an adapted version of the Medical Condition Regard Scale (MCRS). SETTING AND SUBJECTS: Nurses and physicians at primary healthcare centers (PHCCs) in Skåne, Sweden. MAIN OUTCOME MEASURES: Mean MCRS scores, dichotomized responses to MCRS items, and associations between MCRS score and background covariates (age, sex, profession and duration of professional experience). RESULTS: Eighty-nine PHC professionals from 13 PHCCs responded (approximately 39% of relevant workforce). The median MCRS score was 44 for patients with illicit drug use and patients in OAT, and 51 for patients with depression. Drug use and OAT displayed similar minimum, maximum and interquartile range values as well, while scores regarding depression displayed a higher minimum value and smaller spread. No significant associations were found between background covariates and MCRS scores for either drug use or OAT. CONCLUSIONS: The results indicate widespread negative attitudes to PCPDU, with implications for health equity in the clinic. Further studies are needed to see if the results reflect attitudes in Swedish PHC in general.Key PointsPeople with current or previous drug use (PCPDU) often lack necessary primary healthcare (PHC) and are commonly subject to prejudice.Swedish PHC professionals held more negative attitudes toward PCPDU than toward patients with depression.Attitudes toward patients with active drug use and patients in opioid assisted treatment (OAT) were almost identical.Study findings have potential implications for the health of PCPDU as well as health equity in the clinic.Widespread negative attitudes to PCPDU in our sample indicate the need of larger-scale studies of attitudes toward PCPDU in Swedish PHC.

Assessing reliability of naïve respondent-driven sampling samples by using repeated surveys among people who inject drugs (PWID) in New Jersey.

INTRODUCTION: Respondent-driven sampling (RDS) is widely used to sample populations with higher risk of HIV infection for whom no sampling frames exist. However, few studies have been done to assess the reliability of RDS in real world settings. METHODS: We assessed the reliability of naïve RDS samples using five rounds of the National HIV Behavioral Surveillance - People Who Inject Drugs surveys in Newark, New Jersey from 2005 to 2018. Specifically, we compared the distributions of time-insensitive demographic characteristics in temporally adjacent RDS samples with Monte Carlo Two-Sample Kolmogorov-Smirnov Test with 100,000 replicates. The distributions of time-sensitive demographic characteristics were also compared as sensitivity analyses. RESULTS: The study showed that repeated RDS samples among people who inject drugs in the greater Newark area, New Jersey were reliable in most of time-insensitive demographics and recruitment homophily statistics. Sensitivity analyses of time-sensitive demographics also presented consistencies in most of temporally adjacent samples. CONCLUSIONS: In conclusion, RDS has the potential to provide reliable samples, but demographic characteristics of RDS samples may be easily biased by homophily. Future studies using RDS may need to pay more attention to potential homophily bias and consider necessary diagnostic procedures and sample adjustments.

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. METHODS: We developed a model to simulate two fictive cohorts for each city (n=2,997 in Paris and n=2,971 in Strasbourg) i) PWID attending a DCR over the period 2016-2026, ii) PWID attending no DCR. The model accounted for HIV and HCV infections, skin abscesses and related infective endocarditis, drug overdoses and emergency department visits. We estimated the number of health events and associated costs over 2016-2026, the lifetime number of quality-adjusted life-years (QALYs) and costs, and the incremental cost-effectiveness ratio (ICER). RESULTS: The numbers of abscesses and associated infective endocarditis, drug overdoses, and emergency department visits decreased significantly in PWID attending DCRs (-77%, -69%, and -65%, respectively) but the impact on HIV and HCV infections was modest (-11% and -6%, respectively). This resulted in savings of €6.6 (Paris) and €5.8 (Strasbourg) millions of medical costs. The ICER of DRCs was €30,600/QALY (Paris) and €9,200/QALY (Strasbourg). In scenario analysis where drug consumption spaces are implemented inside existing harm reduction structures, these ICERs decreased to €21,400/QALY and €2,500/QALY, respectively. CONCLUSIONS: Our findings show that DCRs are highly effective and efficient to prevent harms in PWID in France, and advocate extending this intervention to other cities by adding drug consumption spaces inside existing harm reduction centers.

Hepatitis B virus infection among illegal drug users in Enugu State, Nigeria: prevalence, immune status, and related risk factors.

INTRODUCTION: Hepatitis B virus infection poses a global health challenge, particularly in low- and middle-income African countries. Illicit drug use exacerbates the problem, with drug users having a higher HBV infection risk and maintaining a quiet transmission pool. This study aimed to determine HBV infection prevalence, immune status, and risk factors among illegal drug users in Enugu State, Nigeria. MATERIALS AND METHODS: A cross-sectional study was conducted in Enugu State, using privileged access interviewer methods to enroll drug users. Pre-tested structured questionnaires were administered after informed consent was obtained. Blood samples were tested for HBsAg, HBsAb, HBeAg, HBeAb, and HBcAb using immunochromatographic rapid test kits. Statistical analysis was performed using SPSS version 25. RESULTS: One hundred drug users were recruited into the study. Overall, 7% of the drug users had HBV infection. 61% were found to be susceptible to HBV infection, 15% showed serological evidence of immunity from HBV vaccination and 1% developed natural immunity from HBV exposure. Significant risk factors for HBV infection were age less than 20 years, young age (≤ 20 years) at drug initiation, being single, injecting drugs more than or equal to 20 times per month and injecting with used syringes. CONCLUSION: This study shows high intermediate endemicity of HBV infection among drug users, low vaccination uptake, and high susceptibility to HBV infection. This calls for the urgent inclusion of drug users in national HBV vaccination campaigns and the adoption of the World Health Organization's recommendations on the prevention of viral hepatitis among people who inject drugs.

Patterns of Health-related Quality of Life in Men Who Inject Drugs: A Survey in Southeast Iran.

OBJECTIVES: Understanding patterns of quality of life in people who inject drugs (PWID) can help healthcare providers plan and manage their health problems in a more focused manner. Therefore, the current study aimed to identify patterns of health-related quality of life in PWID in southeast Iran. METHODS: This cross-sectional study was conducted in southeast Iran on men who had injected drugs at least once during the last year. We used convenience sampling in 2 drop-in centers and venue-based sampling at 85 venues. Demographic characteristics, high-risk behaviors, and health-related quality of life were evaluated using the 5-level EQ-5D version (EQ-5D-5L) questionnaire. Latent profile analysis was used to identify patterns of quality of life. RESULTS: This study enrolled 398 PWID, who had a mean age of 34.1±11.4 years. About 47.9% reported a prison history in the last 10 years, 59.2% had injected drugs in the last month, and 31.6% had a history of sharing syringes. About 46.3% reported having 2 or more sexual partners in the last 6 months, and 14.7% had a history of sex with men. Out of the 5 EQ-5D-5L profiles, the fifth profile had the most people (36.6%). Most variations in quality of life were related to pain and discomfort. CONCLUSIONS: We showed that the pain and discomfort dimension of EQ-5D-5L had more variation in PWID. This finding will be useful for allocating appropriate interventions and resources to promote health-related quality of life in this population.

Alterações sistêmicas e bucais em pacientes usuários de cocaína: uma revisão integrativa da literatura / Cambios sistémicos y orales em pacientes consumidores de cocaína: una revisión bibliográfica integradora / Systemic and oral changes in cocaína-using patients: an integrative literature review

Introdução: A utilização de cocaína é bastante associada ao surgimento de algumas manifestações sistêmicas e também de algumas alterações orais. Objetivo: Identificaras alterações sistêmicas e bucais mais comuns a pacientes usuários de cocaína. Metodologia: Trata-se de uma revisão sistemática da literatura, considerando artigos com texto completo, com restrição de idioma em Português ou Inglês e que tenham sido publicados entre os anos de 2017 a 2022. Usou-se as bases de dados LiLaCS, MedLine e BBO, por via portal Biblioteca Virtual de Saúde, e SciELO. Os artigos excluídosf oram aqueles que não apresentaram relação explícita do uso de cocaína com alguma manifestação sistêmica e/ou bucal. Resultados: Após o processo de triagem,10 artigos foram salvos para serem analisados e 111 foram descartados por não atenderem aos critérios de inclusão. Dos 10 artigosselecionados,40% deles (n=4) trouxeram informações identificando possíveis riscos de desenvolvimento de doenças cardiovasculares sofridas pelos usuários de cocaína, 10%(n=1) identificou problemas cognitivos associados ao uso da cocaína,30% dos artigos (n=3) mostrou as alterações bucais associadas à utilização abusiva de cocaína. Conclusões: Houve a predominância de algumas manifestações sistêmicas e bucais nos indivíduos usuários de cocaína, como doenças cardiovasculares, xerostomia, perfurações no palato, etc. A partir disso, há algumas alterações sistêmicas e bucais provocadas por esse uso. Mediante o risco considerável, faz-se necessário que o Cirurgião-Dentista se atualize sobre essas alterações em pacientes usuários de cocaína visando promover um trabalho transdisciplinare multiprofissional para atender adequadamente às suas necessidades (AU).

Introduction: The use of cocaine is closely associated with the appearance of some systemic manifestations and also some oral alterations.Objective: To identify the most common systemic and oral alterations in cocaine-using patients.Methodology:This is a systematic review of the literature, considering full-text articles, with a language restriction of "Portuguese" or "English" and published between 2017 and 2022. We used the LiLaCS, MedLine and BBO databases, via the Virtual Health Library (VHL) portal, and SciELO.The articles excluded were those that did not explicitly relate cocaine use to some systemic and/or oral manifestation.Results: After the screening process, 10 articles were saved for analysis and 111 were discarded because they did not meet the inclusion criteria. Of the 10 articles selected, 40% (n=4) provided information identifying possible risks of developing cardiovascular diseases suffered by cocaine users, 10% (n=1)identified cognitive problems associated with cocaine use, 30% of the articles (n=3) showed oral alterations associated with cocaine abuse.Conclusions: There has been a predominance of some systemic and oral manifestations in cocaine users, such as cardiovascular diseases, xerostomia, perforations in the palate, etc. Based on this, there are some systemic and oral alterations caused by this use. Given the considerable risk, it is necessary for dentists to be up-to-date on these alterations in cocaine-using patients in order to promote transdisciplinary and multi-professional work to adequately meet their needs (AU).

HTLV in Sweden.

Sweden is a country with a low prevalence of human lymphotropic T-cell virus (HTLV) infection, estimated at < 0.005%, but the infection rate is notably higher in specific risk groups such as HTLV-2 among intravenous drug users (IVDU) and people originating from HTLV-1 highly endemic areas. Thus, in the most recent study from 2012, the prevalence of HTLV-2 among IVDU in Stockholm was 3.2%. However, much of the epidemiological data on HTLV in Sweden stems from studies conducted primarily between the 1990s and 2007, and the impact of migration to Sweden during the past 15 years has not been evaluated. Despite Sweden's status as a country with generally low prevalence of HTLV, it is prudent to anticipate and prepare for several potential challenges associated with HTLV infection in the future. Proactive measures to enhance awareness, alongside strategies to curtail transmission and mitigate complications, are crucial for addressing this relatively rare, but significant health issue. In this work, we review the current epidemiological knowledge about HTLV in Sweden and discuss future Swedish perspectives.

GRAND PLAN: Safety and Efficacy of Glecaprevir/Pibrentasvir for the Treatment of Hepatitis C Virus Infection Among People Initially Disengaged From Health Care Who Use Drugs-A Systematic Multidisciplinary Approach.

Background: GRAND PLAN is a prospective, open-label, phase 4 study. Based at a single center and with a single arm, GRAND PLAN evaluated the safety and efficacy of an 8-week course of glecaprevir/pibrentasvir (G/P) among active drug users with hepatitis C virus (HCV) infection in a population enriched for factors that may reduce treatment uptake and success, such as disengagement from health care and unstable housing. Methods: Participants were ≥19 years old and actively using drugs and were confirmed viremic, noncirrhotic, and HCV treatment naive. All participants provided informed consent before any study procedures. They received G/P for 8 weeks within a multidisciplinary model of care, with daily, weekly, or monthly dispensing of medications to optimize adherence. Results: We identified 117 eligible patients with a median age of 46 years (range, 22-75): 27% were female, 21.4% were Indigenous, 48.7% were unstably housed, and 95.7% were active drug users (94.9% fentanyl). One patient did not start treatment, and 4 underwent <1 week of treatment, leaving 112 completed treatments with 94.6% picking up medications weekly. HCV RNA was undetectable at the end of treatment in all 112 patients. One died of unknown causes shortly after treatment. A cure was demonstrated in 108 of 111 (97.3%) cases at the SVR12 time point (sustained virologic response at ≥12 weeks); the other 3 experienced virologic relapse. Considering the entire cohort, the intent-to-treat success rate was 92.3% (108/117). HCV reinfection was documented at SVR24 in 5 cases, 2 of which were successfully retreated. Conclusions: GRAND PLAN demonstrates that administration of an 8-week course of G/P to inner-city residents with HCV infection leads to a cure >95%. With a short course of treatment, G/P is an attractive option for this population in helping us achieve the World Health Organization's HCV objectives by 2030.

O uso de drogas e seus efeitos na cavidade oral

Objetivos: Descrever as principais manifestações bucais associadas ao uso das drogas lícitas e ilícitas mais utilizadas atualmente, bem como os cuidados que devem ser tomados durante o atendimento odontológico desses pacientes. Revisão de literatura: Na revisão foi abordada a classificação das substâncias químicas, as principais manifestações orais e os cuidados que o cirurgião-dentista deve ter durante o atendimento odontológico. As substâncias descritas foram álcool, tabaco, benzodiazepínicos, maconha, anfetaminas e cocaína/crack. As complicações de saúde bucal associadas ao abuso de drogas podem resultar da exposição direta dos tecidos orais às drogas durante o fumo ou ingestão, da interação biológica das drogas com a fisiologia normal da cavidade oral e dos efeitos das drogas na função cerebral que resultam em um espectro de comportamentos de dependência, como comportamento de risco, falta de higiene e descuido. Considerações finais: O consumo de substâncias psicoativas, seja a curto ou longo prazo, pode desencadear consequências, tanto na saúde geral como na saúde bucal do usuário. Sob essa perspectiva, o cirurgião-dentista deve estar ciente das manifestações orais e sistêmicas causadas pelas substâncias psicoativas e estar capacitado para diagnosticar, tratar ou também encaminhar o usuário, se necessário, visando um cuidado integral e multiprofissional.

Objective: to describe the main oral manifestations associated with the use of the most commonly used licit and illicit drugs today, as well as the care that should be taken during the dental care of these patients. Literature review: The review covered the classification of chemical substances, the main oral manifestations and the care that dentist should take during dental care. The substances described were alcohol, tobacco, benzodiazepines, marijuana, amphetamines and cocaine/crack. Oral health complications associated with drug abuse can result from direct exposure of oral tissues to drugs during smoking or ingestion, from the biological interaction of drugs with the normal physiology of the oral cavity, and from the effects of drugs on brain function that result in a spectrum of addictive behaviors, such as risk behavior, poor hygiene and carelessness. Final considerations: The consumption of psychoactive substances, whether in the short or long term, can have consequences for both the general health and the oral health of the user. From this perspective, the dentist must be aware of the oral and systemic manifestations caused by psychoactive substances and be able to diagnose, treat or also refer the user, if necessary, aiming for comprehensive, multi-professional care.

Clinical characteristics of over-the-counter (OTC) drug abusers in psychiatric practice in Japan: Comparison of single and multiple OTC product abusers.

OBJECTIVE: To examine the clinical characteristics of over-the-counter (OTC) drug abusers in psychiatric practice in Japan. METHOD: We examined the attributes, ICD-10 subcategory, and comorbid mental disorders of patients who mainly abuse OTC products and compared the clinical characteristics of single product and multiple products abusers, using the database of the "2022 Nationwide Mental Hospital Survey of Drug-related Disorders." RESULTS: Among the 2468 subjects included in this survey, 273 (11.1%) used OTC products as main drugs. Of these, 209 (78.3%) and 58 (21.7%) were classified into the single product group and the multiple products group, respectively. Six were excluded for unknown ingredients. By comparing these groups, we found that many of the multiple products group consisted of young women who were recently treated for drug problems. Many subjects in the group also had a short treatment period. No differences were observed between the groups regarding the ICD-10 F1 subcategory, but many subjects in the multiple products group fulfilled the criteria of F6 "disorders of adult personality and behavior." CONCLUSION: OTC products are easily accessible drugs of abuse for young women in Japan. The results of this study indicate the necessity to reconsider the educational approach for preventing drug abuse, which has focused on illicit drugs. The study also indicates that some OTC products, which contain ingredients banned overseas due to their harmful effects, are still sold in Japan and that abusers for those products exist. Measures by the government are considered urgently needed.

Multiple Retained Needles in the Neck of a Drug User: A Case Report.

Retained needles are frequently observed in intravenous drug users. However, an incidental discovery of multiple needles at the neck seldom occurs. These foreign bodies remain either asymptomatic or cause local and central complications that can be fatal. We report the case of a 43-year-old male having a medical record of human immunodeficiency virus and hepatitis C who presented to our department with a 3-day history of a febrile lateral neck swelling. He reported a history of repetitive intravenous drug use and previous abscesses that were surgically drained. We noted a left and tender 8 cm neck swelling with torticollis. Computed tomography scan showed a collected myositis of the sternocleidomastoid muscle in association to multiple metallic foreign bodies at the neck that were compatible with the aspect of broken needles. Imagery also showed a thrombosis of the ipsilateral jugular vein. No central embolism of a foreign body was noted. We performed a surgical drainage of the muscular abscess and managed to retrieve a 1 cm broken needle that was retained at the level of the collection. We did not retrieve the other needles since they were asymptomatic. The patient was placed under intravenous antibiotics for 1 week followed by oral amoxicillin-clavulanate with a total regression of the cellulitis. At the further follow-ups, the rest of the foreign bodies remained asymptomatic. Our study emphasizes on the importance of suspecting a retained foreign body in intravenous drug users to ensure an adequate management of the possible complications and to protect the medical team from incidental needle injuries.
