Sex/gender differences in spontaneous reports to a French Addictovigilance centre.

To specify psychoactive substances and related complications observed in spontaneous reports (SRs) in women versus men, we assessed SRs on substance-linked acute toxicity sent to a French Addictovigilance centre. Over the period 2021-2022, 880 SRs were analysed (33.4% concerned women). Severe complications concerned more men than women (70.3% versus 59.5%; p = 0.0014). In women, the main implicated substances were psychoactive medications (opioids, benzodiazepines). The most frequently reported complication was suicidal behaviour (14.6% versus 7.8%, p = 0.002). In men, SRs concerned mainly illicit substances (cocaine, amphetamines) or misuse of opioid maintenance therapy or nitrous oxide. The main complications in men were infections (12.97% versus 5.4%, p = 0.0006) and neurological troubles (37.6% versus 23.5%, p < 0.0001).Our data highlight sex/gender disparities in substance use and complications, in agreement with recent literature and French national Addictovigilance data.

Do video or telephone consultations impact attendance rates in an addiction medicine specialist outpatient clinic?

BACKGROUND: Effective alcohol and other drugs (AODs) treatment has been proven to increase productivity and reduce costs to the community. Telehealth has previously been proven effective at delivering AOD treatment in the right settings. Yet, Australia's current Medicare funding restricts telephone consultations. AIM: We hypothesise that treatment modality influences attendance rates. Specifically, telephone consultations can remove barriers to accessing treatment and, therefore, can increase attendance. METHODS: We conducted a retrospective audit on our addiction medicine specialist outpatient service from 1 July 2022 to 30 June 2023. A mixed-effects logistic regression model was used to analyse factors associated with attendance rates. RESULTS: There were 576 participants in the study, and 3354 appointments were booked over the 12-month study period. Of these, 2695 were face-to-face, 541 were telephone and 118 were video. The unadjusted raw attendance rate was highest in the telephone group (87.24%), followed by face-to-face (73.02%) and video (44.92%). After adjusting for covariates, telephone consultation was associated with significantly increased odds of attending compared to face-to-face (odds ratio (OR) = 2.60, 95% confidence interval (CI) = 1.90-3.54, P < 0.001). Video consultation was associated with a 69% reduction in the odds of attending compared to face-to-face (OR = 0.31, 95% CI = 0.019-0.49, P < 0.001). CONCLUSIONS: While physical attendance may be required for specific clinical care, telephone consultations are associated with increased attendance and can form an important adjunct to delivering addiction treatment. Given the substantial costs of substance use disorders, this could inform government policies and funding priorities to further improve access and treatment outcomes.

Substance Addiction Rehabilitation Drugs.

The relapse rate of substance abusers is high, and addiction rehabilitation adjunct drugs need to be developed urgently. There have been numerous reports on blocking the formation of substance addiction, but studies on drugs that can alleviate withdrawal symptoms are very limited. Both the dopamine transporter (DAT) hypothesis and D3 dopamine receptor (D3R) hypothesis are proposed. DAT activators reduce the extracellular dopamine level, and D3R antagonists reduce the neuron's sensitivity to dopamine, both of which may exacerbate the withdrawal symptoms subsequently. The D3R partial agonist SK608 has biased signaling properties via the G-protein-dependent pathway but did not induce D3R desensitization and, thus, may be a promising drug for the withdrawal symptoms. Drugs for serotoninergic neurons or GABAergic neurons and anti-inflammatory drugs may have auxiliary effects to addiction treatments. Drugs that promote structural synaptic plasticity are also discussed.

Multiscale topology in interactomic network: from transcriptome to antiaddiction drug repurposing.

The escalating drug addiction crisis in the United States underscores the urgent need for innovative therapeutic strategies. This study embarked on an innovative and rigorous strategy to unearth potential drug repurposing candidates for opioid and cocaine addiction treatment, bridging the gap between transcriptomic data analysis and drug discovery. We initiated our approach by conducting differential gene expression analysis on addiction-related transcriptomic data to identify key genes. We propose a novel topological differentiation to identify key genes from a protein-protein interaction network derived from DEGs. This method utilizes persistent Laplacians to accurately single out pivotal nodes within the network, conducting this analysis in a multiscale manner to ensure high reliability. Through rigorous literature validation, pathway analysis and data-availability scrutiny, we identified three pivotal molecular targets, mTOR, mGluR5 and NMDAR, for drug repurposing from DrugBank. We crafted machine learning models employing two natural language processing (NLP)-based embeddings and a traditional 2D fingerprint, which demonstrated robust predictive ability in gauging binding affinities of DrugBank compounds to selected targets. Furthermore, we elucidated the interactions of promising drugs with the targets and evaluated their drug-likeness. This study delineates a multi-faceted and comprehensive analytical framework, amalgamating bioinformatics, topological data analysis and machine learning, for drug repurposing in addiction treatment, setting the stage for subsequent experimental validation. The versatility of the methods we developed allows for applications across a range of diseases and transcriptomic datasets.

Pilot study of a community pharmacist led program to treat hepatitis C virus among people who inject drugs.

Background: People who inject drugs (PWID) are a key population for treatment with direct-acting antiviral medications (DAAs) to eliminate hepatitis C virus (HCV). We developed a Pharmacist, Physician, and Patient Navigator Collaborative Care Model (PPP-CCM) for delivery of HCV treatment; this study describes clinical outcomes related to HCV treatment (initial evaluation, treatment initiation, completion, and cure), as well as patient satisfaction. Methods: We conducted a single-arm prospective pilot study of adult PWID living with HCV. Participants completed baseline and six-month follow-up surveys, and treatment and outcomes were abstracted from electronic health records. Primary outcome was linkage to pharmacist for HCV evaluation; secondary outcomes included DAA initiation, completion, and cure, as well as patient-reported satisfaction. Results: Of the 40 PWID enrolled, mean age was 43.6 years, 12 (30 %) were female, 20 (50 %) were non-white, and 15 (38 %) were unhoused. Thirty-eight (95 %) were successfully linked to the pharmacist for initial evaluation. Of those, 21/38 (55 %) initiated DAAs, and 16/21 (76 %) completed treatment. Among those completing treatment who had viral load data to document whether they achieved "sustained virologic response", i.e. cure, 10/11 (91 %) were found to be cured. There was high satisfaction with 100 % responding "agree or strongly agree" that they had a positive experience with the pharmacist. Conclusion: Nearly all participants in this pilot were successfully linked to the pharmacist for evaluation, and more than half were started on DAAs; results provide preliminary evidence of feasibility of pharmacist-led models of HCV treatment for PWID. Clinicaltrialsgov registration number: NCT04698629.

Beneficios de la atención telefónica durante la pandemia covid19 en la adherencia terapéutica en pacientes con alcoholismo y otras adicciones / Advantages of telephone assistance on adherence to treatment in patients with alcohol and other addictions during the Covid19 pandemic

La pandemia por covid19 ha generado muchas publicaciones acerca de su influencia en el tratamiento y evolución de personas con un trastorno por uso de sustancias, con resultados contradictorios, a veces basadas en datos y otras en inferencias indirectas de otros datos. En este trabajo se estudia la adherencia y tasas de abstinencia de pacientes que inician tratamiento en una Unidad de Conductas Adictivas durante la pandemia, respecto a otros que acudieron el año previo y comparando los que hicieron visita presencial o telefónica. Los resultados indicaron mejor adherencia al mes de seguimiento en los pacientes del periodo covid19 y en los que fueron atendidos telefónicamente. A los 3 y 12 meses se mantuvo una mejor adherencia, aunque no significativa estadísticamente. Respecto a la abstinencia, el pequeño tamaño de la muestra dificultó obtener diferencias significativas. Se concluye que la pandemia, aunque ha significado una disminución del número de inicios de tratamientos por consumo de sustancias, también ha repercutido en una mayor adherencia a corto y medio plazo. La atención telefónica puede jugar un papel importante y positivo en este aspecto, complementario a otros recursos e intervenciones. (AU)

The Covid19 pandemic has led to many publications about its influence on the treatment and evolution of individuals with a substance use disorder, leading to contradictory results. In this study, the adherence and abstinence rates of patients who started treatment in an Addictive Behavior Unit during the pandemic are analyzed, compared with others who attended the previous year and comparing those who were attended in person or by phone. The results indicate that during the Covid19 period, patients had greater adherence to treatment after one month of follow up and when attended to by phone. At 3 and 12 months, greater adherence was maintained, although it was not statistically significant. Regarding abstinence, the small sample size made it difficult to obtain significant differences. The conclusion is that, despite a quantitative decrease in the number of patients beginning drug treatment, in qualitative terms the pandemic led to greater adherence in the short and medium term. Telephone attention can play an important and positive role at this point, complementary to other resources and interventions. (AU)

The effect of gamification-based training on the knowledge, attitudes, and academic achievement of male adolescents in preventing substance and internet addiction.

BACKGROUND: Preventing addiction through training takes precedence over treatment and plays a crucial role in enhancing the well-being of adolescents. Utilizing inclusive and participatory methods can significantly enhance the effectiveness of education. Numerous studies have demonstrated that gamification, as an interactive and comprehensive approach, has the potential to boost teenagers' motivation to engage in learning and contributes to better comprehension. AIM: This study aimed to assess the impact of gamification-based training to prevent substance and internet addiction on the knowledge and attitudes of male adolescents. Additionally, the study examined this educational program's effects on male adolescents' academic achievement. METHODS: This study employed a quasi-experimental design with a control group. One hundred fourteen male adolescents were randomly assigned to the intervention or control groups. They completed a pre-intervention questionnaire assessing addiction-related knowledge, attitudes, and academic achievement. Subsequently, the intervention group received the gamification-based drug and internet addiction prevention training. Post-tests were conducted immediately after the training and again one month later for both groups. RESULTS: Before the intervention, there were no significant differences in knowledge of substance and internet addiction, attitudes toward substances and the Internet, and academic achievement between the intervention and control groups (P > 0.05). However, after the intervention, the intervention group demonstrated significantly higher scores in knowledge of substance and internet addiction, attitudes toward substances and the Internet, and academic achievement compared to the control group (P < 0.001). CONCLUSION: The current study highlights the positive impact of gamification-based training on enhancing male adolescents' knowledge, attitudes, and academic achievement.

[Craving in Substance Addiction: A Concept Analysis].

Craving in the context of substance addiction is considered an important predictor of substance addictive disorders and relapse risk. Behavior therapy, mindfulness, and exercise may be employed clinically to alleviate cravings. However, many scholars have offered various interpretations of craving in substance addiction. Despite these definitions sharing some overlapping elements, a consensus has yet to be reached. Although many studies have presented the effects of and interventions for craving to alleviate substance addiction, this issue has rarely been explored in the clinical nursing context, resulting in a lack of understanding of the concept of craving in substance addiction among nursing professionals. Therefore, based on the conceptual analysis approach proposed by Walker and Avant (2019), a conceptual analysis of craving in substance addiction was conducted in this study by interpreting and defining the characteristics, pre-factors, consequences, and effects of craving in substance addiction using examples of typical, borderline, related, and contrary cases. The findings are intended to help nurses gain a more comprehensive understanding of craving in substance addiction and become more familiar with cases requiring clinical care.

The role of the cerebellum in internet gaming disorder-A systematic review.

Recent studies increasingly highlight involvement of the cerebellum in drug craving and addiction. However, its exact role, that is, whether the cerebellum is a critical component of a brain network underlying addictive behaviour, or whether it rather is a facilitator or mediator, is still unclear. Findings concerning the newly recognized internet gaming disorder (IGD) suggest that changes in cerebellar connectivity and functioning are associated with behavioural/non-substance addiction. Here, we systematically review the literature on IGD and cerebellar involvement following the PRISMA guidelines. A total of 13 neuroimaging studies met the inclusion criteria. Studies utilized a broad range of diagnostic instruments and resulting cut-off criteria, rendering it difficult to compare findings. Results on altered cerebro-cerebellar connectivity in patients with IGD are mixed; most studies report altered or increased functional connectivity. Moreover, decreased cerebellar grey matter volume is reported. Studies have further indicated that differential activation patterns in the cerebellum may enable discrimination between healthy subjects and subjects with IGD, even allowing for prediction of treatment outcomes. Given the strong connectivity between the cerebellum and cerebral regions, the cerebellum may act as an intermediary between regions involved in craving and addiction and consequently affect symptoms of IGD. Results suggest differential involvement of the cerebellar lobes, emphasizing a need for high-resolution parcellation of the cerebellum in future studies. However, the studies included in the present review have small sample sizes and include mostly male participants. Thus, results may have limited generalizability yet highlight a crucial role of the cerebellum in IGD that needs further investigation.

Analysis of the brain transcriptome for substance-associated genes: An update on large-scale genome-wide association studies.

Substance use disorder (SUD) arises from the initiation to subsequent regular, irregular and harmful use of substances such as alcohol, tobacco/nicotine and cannabis. While thousands of genetic variants have been identified from recent large-scale genome-wide association studies (GWAS), understanding their functions in substance involvement and investigating the mechanisms by which they act in the addiction circuits remains challenging. In this study, we re-analysed the brain regional transcriptome data from the most comprehensive postmortem transcriptomic study, with a focus on up- or down-regulation of substance-associated protein-coding genes in the addiction circuit-related brain regions (AddictRegions), including six cortical and 11 subcortical regions. We found that substance-associated genes were overrepresented in AddictRegions. Interestingly, we observed a greater degree of genetic overlap between initiation and use and between use and SUD than between initiation and SUD. Moreover, substance initiation, use and SUD-associated genes tend to shift their enriched AddictRegions from the cortical for initiation and, to a lesser extent, substance use to subcortical regions for SUD (e.g., thalamus, substantia nigra and ventral tegmental area). We also uncovered a pattern of coordinated cortical up-regulation and subcortical down-regulation for the genes associated with tobacco initiation and alcohol use. Moreover, the Gene Ontology terms of glutamate receptor activity and neurotransmitter binding were most significantly overrepresented in AddictRegion-upregulated, substance-associated genes, with the strongest enrichment for those involved in common substance use behaviours. Overall, our analysis provides a resource of AddictRegion-related transcriptomes for studying substance-associated genes and generates intriguing insights into the genetic control of substance initiation, use and SUD.

Stigma Experienced by Perinatal Women with Opioid Dependency in the United States: A Qualitative Meta-Synthesis.

Stigma is a barrier to accessing care and treatment for perinatal women with pain and opioid dependency, resulting in increased maternal/neonatal morbidity and mortality, prolonged neonatal hospitalizations, and increased healthcare-related costs. This theory-generating qualitative meta-synthesis includes 18 qualitative research reports and describes the stigma-related experiences of perinatal women with opioid dependency. A model emerged consisting of cyclical yet pivotal care points, facilitators/deterrents of stigma, and stigma experiences including infant-associative stigma. Findings of this qualitative meta-synthesis include the following: (a) Perinatal stigma experiences may prevent women from accessing care; (b) Infant-associative stigma may influence the woman to deflect stigma from her infant onto herself; and (c) There is the risk of mothers withdrawing their infants from healthcare to protect from future anticipated stigma. Implications reveal ideal time points to enact healthcare interventions to reduce perinatal stigma experiences and its consequences on maternal/child health and wellness.

"A Profound, Abiding Hatred": An Analysis of Hermann Goering's Alleged Morphine Addiction.

Hermann Goering, one of the most prominent members of the Nazi Party and for many years the presumed heir to Adolf Hitler, had a well-known history of morphine addiction. By the last days of the Second World War, he was widely considered by his contemporaries to have been completely incapacitated by his addiction. In this article, we argue that Goering's addiction, while possibly present, was purposefully exaggerated by his rivals for political purposes. His habit of ingesting paracodeine pills may have been a crude form of opioid maintenance therapy, similar to that of methadone today. Ultimately, his history of substance abuse had no significant impact on his capacity, ruthlessness, and leading role in Nazi crimes.

The Efficacy of Telepsychiatry in Addiction Patients: A Systematic Review.

Psychiatry is one of the many medical subspecialties that have benefited from the advent of telemedicine. Substance abuse treatment via telepsychiatry expeditiously increased with the start of the pandemic and has brought changes to its rules and regulations. In this study, we focused on the prognosis of substance abuse patients treated with telepsychiatry, the various changes that occurred during the pandemic, and the difficulties faced by clinicians using telepsychiatry. PubMed and Google Scholar were searched for relevant articles between January 2010 and July 2022 using both broad and narrow keywords in addition to the MeSH (Medical Subject Heading) approach. The total number of records found was 765. Strict criteria for inclusion and exclusion ensured that only relevant information was collected. After removing duplicates, irrelevant studies, and research that did not meet the inclusion criteria, we were left with 373 studies from both electronic databases. From those, we ultimately retrieved 35 studies, which were subjected to a thorough content search and quality evaluation with the help of specialized instruments, and a total of 19 papers were included in our systematic review. We concluded that telepsychiatry use for substance abuse patients increased during the pandemic, and the prognosis of these patients treated with telepsychiatry was similar to that of in-person treatment. However, a combination of telepsychiatry with in-person sessions showed much better results.

A Systematic Review Assessing the Impact of Vitamin D Levels on Adult Patients with Lymphoid Malignancies.

Vitamin D deficiency has been correlated with various conditions, including the risk of developing lymphoid malignancies. This systematic review aimed to assess the association between vitamin D levels at diagnosis of lymphoid malignancies, patient outcomes, and survival. A systematic review was conducted, encompassing 15 studies published until January 2023, involving 4503 patients, examining the relationship between vitamin D and lymphoid cancers. The median age of the patients was 56.5 years, with a median follow-up duration of approximately 36 months across studies. The overall median vitamin D level at initial measurement was 20.4 ng/mL, while a <20 ng/mL threshold was used to define vitamin D insufficiency. The results demonstrated significant associations between vitamin D levels and patient outcomes in several lymphoid malignancies, with a pooled risk in disease progression of 1.93 and a pooled hazard ratio of 2.06 for overall survival in patients with 25-(OH)D levels below the normal threshold of 20 ng/mL. Among findings, it was demonstrated that supplemental vitamin D improves the chemosensitivity of tumors by reducing the rate of tumor growth compared with vitamin D or chemotherapy alone. Vitamin D had a protective effect for patients with DLBCL under R-CHOP treatment, while vitamin D insufficiency was associated with the impairment of rituximab treatment and showed worse clinical outcomes in chimeric antigen receptor T-cell (CAR-T) recipients. Although one study found no association between vitamin D deficiency and the cause of death, most associated vitamin D insufficiency with early clinical failure and lower survival probability. In conclusion, his systematic review highlights the importance of vitamin D levels in the prognosis and survival of patients with lymphoid malignancies. Further research is needed to better understand the underlying mechanisms and explore the potential benefits of vitamin D supplementation in managing these cancers.

Comparison of binge-eating disorder and food addiction.

In the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, binge-eating disorder (BED) is classified as episodes of binge eating while not being hungry, eating too fast until feeling uncomfortably full, or eating in solitude with feelings of shame and disgust after eating, without compensatory mechanisms. The controversial disorder food addiction (FA) is characterized by overconsumption, cravings, failure to cut down on amounts of food, and withdrawal and tolerance to overeating. In this narrative review, we aimed to comprehensively characterize and compare BED and FA. We searched PubMed using the keywords "binge-eating disorder" and "food addiction." We finally included 51 publications according to topic specificity, credibility, the authors' reputation, and non-bias criteria. BED is characterized by concerns about dietary issues, body shape, and weight as well as depressive symptoms and brooding rumination. FA can be divided into substance addiction and behavioral addiction, which can be differentiated using a list of criteria including hunger, taste, pleasure, function of food, loss of social connections, weight concerns, and awareness about the disorder. Further research is needed to further characterize and distinguish BED and FA.

Characteristics of substance-addicted mothers that predict graduation from the family treatment court.

INTRODUCTION: In the United States, substance addiction is a major contributing factor to incarceration of mothers and separation of children from their families. Five hundred Family Treatment Courts (FTC) operate across the country to combat the growing problem of women addicted to drugs. The FTC model provides mothers with substance addiction treatment, intensive judicial monitoring, repeated drug testing, counseling, incentives or sanctions, and case management with the goal of reaching long-term sobriety and reunification with their children. DESIGN: This retrospective study examined the relationship between sociodemographic characteristics and substance use characteristics, in predicting participants' graduations from the FTC program. METHODS: Data were gathered from 317 participants from five Family Treatment Courts in the southeastern United States and analyzed using logistic regression. RESULTS: Participants who completed the FTC program were more likely to be older, completed Cognitive Behavioral Training, completed high school, and Caucasian. CONCLUSION: Age and completion of Cognitive Behavioral Therapy were the greatest predictors of graduating from the Family Treatment Court. These results convey the need for development of interventions tailored to each participant's age to maximize the success of the FTC participants. In addition, Cognitive Behavioral Therapy should be integrated into all FTC programs. CLINICAL RELEVANCE: The findings from this study will offer research scholars a foundation for designing future studies, aid researchers in creating interventions to increase success in substance addiction treatment programs, and contribute to the framework for theory development. In addition, understanding characteristics that may influence graduation from the Family Treatment Court will provide valuable information on developing interventions to support participants' success.

Social media use and abuse: Different profiles of users and their associations with addictive behaviours.

Introduction: Social media use has become increasingly prevalent worldwide. Simultaneously, concerns surrounding social media abuse/problematic use, which resembles behavioural and substance addictions, have proliferated. This has prompted the introduction of 'Social Media Addiction' [SMA], as a condition requiring clarifications regarding its definition, assessment and associations with other addictions. Thus, this study aimed to: (a) advance knowledge on the typology/structure of SMA symptoms experienced and: (b) explore the association of these typologies with addictive behaviours related to gaming, gambling, alcohol, smoking, drug abuse, sex (including porn), shopping, internet use, and exercise. Methods: A sample of 968 [Mage = 29.5, SDage = 9.36, nmales = 622 (64.3 %), nfemales = 315, (32.5 %)] adults was surveyed regarding their SMA experiences, using the Bergen Social Media Addiction Scale (BSMAS). Their experiences of Gaming, Internet, Gambling, Alcohol, Cigarette, Drug, Sex, Shopping and Exercise addictions were additionally assessed, and latent profile analysis (LPA) was implemented. Results: Three distinct profiles were revealed, based on the severity of one's SMA symptoms: 'low', 'moderate' and 'high' risk. Subsequent ANOVA analyses suggested that participants classified as 'high' risk indicated significantly higher behaviours related to internet, gambling, gaming, sex and in particular shopping addictions. Conclusions: Results support SMA as a unitary construct, while they potentially challenge the distinction between technological and behavioural addictions. Findings also imply that the assessment of those presenting with SMA behaviours, as well as prevention and intervention targeting SMA at risk groups, should consider other comorbid addictions.

'Can we predict aggression?'-Determining the predictors of aggression among individuals with substance use disorder in China undergoing enforced detoxification through machine learning.

BACKGROUND: The general aggression model has shown that both individual and situational factors can predict aggression. However, past research has tended to discuss these two factors separately, which might lead to inconsistency. This study addresses this gap by examining the importance of each predictor of aggression in a Chinese compulsory drug treatment population and further explores the predictors of aggression in various substance use disorder populations. METHOD: Analyses were conducted using a sample of 894 male participants (mean = 38.30, SD = 8.38) in Chinese compulsory drug rehab. A machine learning model named LightGBM was employed to make predictions. We then used a game-theoretic explanatory technique, SHAP, to estimate the effect of predictors. RESULTS: In the full-sample model, psychological security, parental conflict, and impulsivity were the top 3 predictors. Depression, childhood abuse, and alexithymia positively predicted aggression, whereas psychological security, family cohesion, and gratitude negatively predicted aggression. There were significant differences in the predictive effects of depressants and stimulants. Although the importance of predictors varied between drug-use groups, several individual and situational factors were consistently the most important predictors. LIMITATIONS: All participants in this study were male, and the data were acquired through self-reports from the participants. Domestic and nondomestic aggression are not distinguished. Additionally, our findings cannot support causal conclusions. CONCLUSION: This study tested a series of classical theories of the predictors of aggression in China's compulsory drug treatment context and extended the ideas of the GAM to various substance use disorder groups. The findings have important implications for aggression treatment.
