RESUMEN

BACKGROUND: In liaison psychiatry, issues related to multiple substance use disorders are encountered, but systematic assessment and treatment protocols are lacking. The implementation of psychoeducation groups with earlier access could be one solution, but it raises the question of how to systematically approach psychoeducation for multiple substance use disorders. SUBJECT AND METHOD: Based on a narrative review of multiple substance use disorders in liaison psychiatry and the proposed treatments, we aimed to identify the possible systematisation of standardised psychoeducation. RESULTS: The triadic model of interoception-impulsivity-addiction emerged as a general approach to addressing addiction issues and could serve as a foundation for the standardisation of psychoeducation. CONCLUSION: Prospective studies on the impact of systematised brief psychoeducational interventions on multiple substance use disorders in the patient treatment plan are to be developed.

RESUMEN

Introduction: The aim of this study was to comprehensively review existing treatments for impulsivity and compulsivity in non-substance addictions, driven by the importance of these factors in addictive disorder development and treatment efficacy. Methods: A systematic review carried out following PRISMA guidelines identified 14 articles from a total of 764 studies, highlighting the limited literature that is available on psychological treatments for non-substance addictions, in particular studies focusing on impulsivity and compulsivity. The studies were categorized by behavioral addiction type. Results: For compulsive sexual behavior and problematic pornography use, cognitive-behavioral therapy (CBT) has shown significant improvements in compulsivity. In gambling disorder, interventions like cognitive bias modification and motivational interviewing combined with CBT have been effective in reducing impulsivity. Cognitive-behavioral therapy was advocated for compulsive shopping, although results varied. For problematic internet use, dialectical behavior therapy and acceptance and commitment therapy have been effective in addressing impulsivity. Despite literature supporting CBT for most behavioral addictions, the review noted that some articles indicate that dialectical behavior therapy and acceptance and commitment therapy were also effective for problematic internet use, suggesting different underlying mechanisms for this type of addiction. Discussion: It also highlighted limitations, including the small number of studies and the lack of standardized assessment measures. Further research is needed to understand underlying mechanisms and develop tailored treatments for impulsivity and compulsivity in non-substance addictions. These findings offer new directions for research and intervention guidelines in behavioral addictions.

RESUMEN

Pleural mesothelioma (PM) is an aggressive cancer with limited treatment options. In particular, the frequent loss of tumor suppressors, a key oncogenic driver of the disease that is therapeutically intractable, has hampered the development of targeted cancer therapies. Here, we interrogate the PM genome using CRISPR-mediated gene editing to systematically uncover PM cell susceptibilities and provide an evidence-based rationale for targeted cancer drug discovery. This analysis has allowed us to identify with high confidence numerous known and novel gene dependencies that are surprisingly highly enriched for non-oncogenic pathways involved in response to various stress stimuli, in particular DNA damage and transcriptional dysregulation. By integrating genomic analysis with a series of in vitro and in vivo functional studies, we validate and prioritize several non-oncogene addictions conferred by CDK7, CHK1, HDAC3, RAD51, TPX2, and UBA1 as targetable vulnerabilities, revealing previously unappreciated aspects of PM biology. Our findings support the growing consensus that stress-responsive non-oncogenic signaling plays a key role in the initiation and progression of PM and provide a functional blueprint for the development of unprecedented targeted therapies to combat this formidable disease.

RESUMEN

The number of people immersed in excessive gaming has increased in this age of rapid digitalization. The World Health Organization and American Psychiatric Association Organization recognize a gaming disorder as a condition that results in significant problems in daily life as a result of excessive gaming. Both organizations emphasize the similarities to behavioral addictions such as gambling. We examined the appropriate usage of video games from the perspectives of health and management in this study. For the general population, video games provide positive impacts such as stress alleviation and memory improvement. Game playing leads to a loss of time and money for the individual. It also has a negative impact on the individual's family and social life, evolving into a social problem. Gaming addiction is often accompanied by psychological disorders and other addictions, and long-term medical treatment, including approaches to the individual's psychological background and cognitive-behavioral therapy, is necessary. Therefore, the prevention of gaming disorder is essential. From a societal standpoint, action is required in three contexts: the government, game developers, and within the household as a whole. Simultaneously, the public needs to understand the positive potential of gaming, such as e-sports.

RESUMEN

Background: The video game industry has introduced a new form of monetization through microtransactions. A controversial example has been the so-called "loot boxes" (LBs) as virtual objects, which are randomized and bought with legal money. In recent years, LBs have come to connect 2 distinct problem behaviors, namely internet gaming disorder (IGD) and online gambling disorder (OGD). Many association studies have been conducted on the 3 constructs, but few have delved into the relationship of problematic use of LBs (PU-LB) with IGD and OGD. Objective: This study aims to explore the mediating role of the PU-LB between IGD and OGD. Methods: This cross-sectional and analytical study used incidental sampling in 24 Spanish schools. The final sample consisted of 542 participants (male: n=523, 96.5%; age: range 11-30 y) who played video games, bought LBs, and had gambled online in the last 12 months. Participants then completed the Spanish versions of the Internet Gaming Disorder Scale-Short Form, Online Gambling Disorder Questionnaire, and PU-LB scale. Results: IGD scores were found to be significantly associated with both PU-LB (r=0.473, P<.001) and OGD (r=0.209, P<.001). Moreover, PU-LB was significantly associated with OGD (r=0.351, P<.001). The structural equation model results indicated that IGD had no significant direct effect on OGD (P=.903). However, the indirect effect of IGD on OGD through PU-LB was significant (P<.001). Therefore, PU-LB fully mediated the relationship between IGD and OGD. Furthermore, these results were found in the subsamples of both minors (<18 y) and young adults (≥18 y). Conclusions: It is suggested that there is a mediation effect of problematic LB use between internet gambling and online gambling problems in both minors and young adults. This has potential practical implications by providing more evidence on how LBs have become a hinge feature between 2 clinically relevant and independent issues. In this regard, adequate industry self-regulation is needed, and effective legislation for the protection of minors is necessary.

RESUMEN

The I-PACE model suggests that Internet-use disorders result from the interplay of individual vulnerabilities and cognitive and affective processes. As in substance use disorders, Pavlovian conditioning processes are attributed a key role. However, and despite progress in identifying individual vulnerabilities, factors influencing appetitive conditioning remain poorly understood. We therefore conducted a Pavlovian conditioning experiment in which individuals with risky as well as non-problematic use of either gaming or buying-shopping applications learned to associate different abstract stimuli with either gaming or buying-shopping. Regression analyses were used to identify individual characteristics influencing awareness of the experimental contingencies, speed of acquisition of awareness and the magnitude of the conditioned emotional responses regarding pleasantness and arousal ratings of the stimuli. Results demonstrated successful Pavlovian conditioning and an attentional bias towards reward-predicting cues. Awareness of the experimental contingencies was linked solely to cognitive abilities, while the speed of acquisition of awareness and the magnitude of conditioned responses was influenced by specific personality characteristics, experiences of compensation from using the application and severity of problematic use. Importantly, certain characteristics specifically predicted the magnitude of the conditioned response towards gaming, while others specifically predicted the response towards buying-shopping, highlighting differing vulnerabilities. These findings underscore the importance of targeted interventions and prevention strategies tailored to these specific vulnerability factors. Further implications and limitations are discussed.

RESUMEN

The United States Food and Drug Administration (FDA) and other agencies have warned e-cigarette to companies to stop selling vaping products that look like toys because these products could attract youth to nicotine use. The vaping industry has gone a step further, producing vaping devices that are fully functional video games. We have observed several new vaping devices that contain youth-oriented video games such as Pac-Man, Tetris, Mario, Q*bert, and virtual pets. Some of these games reward users for each puff of nicotine. The incorporation of video games into vaping devices raises public health concerns regarding the potential appeal to younger users and the potential to escalate nicotine use and dependence. It is crucial to address these devices through robust policy, educational initiatives, and enforcement of existing policies.

RESUMEN

BACKGROUND: Internet gaming disorder among university students has become a great concern for university counsellors worldwide since the COVID-19 pandemic. The factors influencing the development of internet gaming disorder in students during the COVID-19 pandemic could be different from those before the pandemic. OBJECTIVE: This study aims to explore the associations among social isolation, self-control, and internet gaming disorder in Chinese university students and to examine whether self-control mediates the positive effects of social isolation on internet gaming disorder. METHODS: A cross-sectional survey was employed to collect data from university students in Shandong province of China from April to September 2022. The Isolation subscale of the Self-Compassion Scale, Self-Control Scale, and Internet Gaming Disorder Scale were used to assess the social isolation, self-control, and internet gaming disorder among university students, respectively. Models 4 and 5 of PROCESS software were used to analyze the mediating role of self-control and the moderating role of gender on the association between social isolation and internet gaming disorder. RESULTS: A total of 479 students were recruited from 6 universities located in 3 different regions of Shandong, China. Students had low levels of internet gaming disorder and moderate levels of social isolation and self-control, with mean scores of 8.94 (SD 9.06), 12.04 (SD 3.53), and 57.15 (SD 8.44), respectively. Social isolation was positively correlated with internet gaming disorder (r=0.217; P<.001), and self-control was negatively correlated with social isolation (r=-0.355; P<.001) and internet gaming disorder (r=-0.260; P<.001). Self-control played a mediating role in the association between social isolation and internet gaming disorder (ß=-.185, 95% CI -.295 to -.087). The effects of social isolation on internet gaming disorder among female students were lower than those among male students. CONCLUSIONS: Self-control was a mediator in the association between social isolation and internet gaming disorder. Moreover, gender played a moderating role in the association between social isolation and internet gaming disorder. This study highlights the need to alleviate the development of internet gaming disorder among students during a pandemic, especially that of male students. Effective interventions that lessen social isolation and promote self-control should be developed.

RESUMEN

Clonidine operates through agonism at the alpha-2A receptor, a specific subtype of the alpha-2-adrenergic receptor located predominantly in the prefrontal cortex. By inhibiting the release of norepinephrine, which is responsible for withdrawal symptoms, clonidine effectively addresses withdrawal-related conditions such as anxiety, hypertension, and tachycardia. The groundbreaking work by Gold et al. demonstrated clonidine's ability to counteract the effects of locus coeruleus stimulation, reshaping the understanding of opioid withdrawal within the field. In the 1980s, the efficacy of clonidine in facilitating the transition to long-acting injectable naltrexone was confirmed for individuals motivated to overcome opioid use disorders (OUDs), including physicians and executives. Despite challenges with compliance, naltrexone offers sustained blockade of opioid receptors, reducing the risk of overdose, intoxication, and relapse in motivated patients in recovery. The development of clonidine and naltrexone as treatment modalities for OUDs, and potentially other addictions, including behavioral ones, underscores the potential for translating neurobiological advancements from preclinical models (bench) to clinical practice (bedside), ushering in innovative approaches to addiction treatment.

RESUMEN

BACKGROUND: Globally almost one third of adults with chronic non-cancer pain (CNCP) are prescribed opioids. Prevention of opioid dependence among these patients is a public health priority. AIM: Synthesise the evidence on the effectiveness of primary care-based interventions for secondary prevention of opioid dependence in CNCP patients on pharmaceutical opioids. DESIGN & SETTING: Systematic review of randomised controlled trials (RCTs) and comparative non-randomised studies of interventions from high-income countries. METHOD: We searched five databases for studies on non-tapering secondary prevention interventions such as tools for predicting dependence, screening tools for early recognition of dependence, prescribing/medication monitoring, and specialist support. We examined multiple outcomes, including reduction in opioid dosage. Primary analyses were restricted to RCTs with data synthesised using an effect direction plot. Risk of bias was assessed using the Cochrane risk of bias (RoB2) tool. RESULTS: Of 7,102 identified reports, 18 studies were eligible (8 RCTs). Most used multiple interventions/components. Of the seven RCTs at low risk of bias or 'some concerns', five showed a positive intervention effect on at least one relevant outcome, four of which included a nurse care manager and/or other specialist support. The remaining two RCTs showed no positive effect of automated symptom monitoring and optimised analgesic management by a nurse care manager/physician pain specialist team, or of a mobile opioid management app. CONCLUSION: We identify a clear need for further adequately powered high quality studies. The conclusions that can be drawn on intervention effectiveness are limited by the sparsity and inconsistency of available data.

RESUMEN

Even though gaming and gambling bear similar problematic behavioral aspects, there are no recognizable neurophysiological biomarkers or features characterizing and/or distinguishing these conditions. A systematic review of the literature with a focus on methods was performed in PubMed, Scopus, Web of Science (Web of Science Core Collection), EBSCOhost Research Databases (APA PsycINFO; APA PsycArticles; OpenDissertations; ERIC) databases. Following search terms were used to search the databases: ERP, "event related potential*", EP, "evoked potential*", SS, "steady state", EEG, electroencephal*; gam*. Data about the participants (total number, gender, age), main aim of the study and information about the experimental setup (experimental task description, stimuli used, ERPs measured (latency windows and placement of the electrodes), process evaluated) was extracted. A total of 24 studies were revised (problematic gaming - 16, pathological gambling - 8). The experimental protocols could be grouped into 3 main target domains (Cue-reactivity, General Information processing and Reward Processes & Risk Assessment). Sample-related limitations (small sample sizes, gender differences, differences between the groups regarding potential confounding variables) and heterogeneity regarding the experimental tasks, implementation and interpretation reviewed. Gambling-related research is highly focused on the investigation of the reward-related processes, whereas gaming-related research is mostly focused on the altered aspects of more general information processing. A vast heterogeneity regarding the ERP experimental paradigms being used and lack of clear guidelines and standardized procedures prevents identification of measures capable to reliably discriminate or characterize the population susceptible to addictive behavior or being able to diagnose and monitor these disorders.

RESUMEN

BACKGROUND: The European Guideline for the Diagnosis and Treatment of Insomnia recommends, for all age groups, restrictive, short-term and periodic use of potentially addictive hypnotics. As in other European countries, in Norway, actual practice involving elderly patients differs substantially from this recommendation, as shown by the persistent high frequency of regular prescriptions of addictive hypnotics. AIM: To explore experienced Norwegian general practitioners' (GPs') views of the regular prescription of addictive hypnotics to patients older than 70 years living at home. DESIGN & SETTING: In-depth individual interviews of a purposive sample of experienced specialists in family medicine at GP offices in Southern Norway. METHOD: Reflexive thematic cross-case analysis. RESULTS: Most of the 11 GPs interviewed had more than 10 elderly patients who were prescribed hypnotics for daily use and the same number for intermittent prescription. Almost all prescriptions were of z-hypnotics. The GPs knew this was contrary to the guideline. Many were at ease with this fact. They emphasised the need to avoid creating new dependencies. The GPs considered these patients a selected minority within this age group with serious sleep problems, for whom few realistic alternatives were available and whose tolerance over time was better than expected. This logic of pragmatic practice reflected a patient-centred approach and respect for the patients' view in a shared decision-making process combined with challenges of limited alternatives and resources. CONCLUSION: A zero vision on the prescription of addictive hypnotics to the elderly may neither be prudent nor realistic in the context of general practice.

RESUMEN

This empirical research on children's poverty and the accompanying risk behavior was conducted in the Baktalórántháza micro-region, in one of the most disadvantaged micro-regions of Hungary. The study, completed in 2023, was conducted utilizing three methods, a questionnaire for families, interviews, and focus group interviews with social professionals working in the settlements. The region is one of the ten micro-regions with the highest poverty rate in the country. The majority of the population only has an elementary education, and the proportion of graduates is much lower than the national average. The proportion of households with three or more children is higher than the national average and the proportion of unemployed people in households with children is twice as high as the national average. Based on the experience of social workers working in the area, in addition to smoking and drinking alcohol, the consumption of psychoactive and psychotropic substances has increased among adolescents and young adults. Based on various indicators, children regularly consume illegal drugs. The origin and composition of these drugs are typically unknown. According to the reports by drug users, everyday life is easier, and they can escape from problems when under the influence of drugs. Based on the observations of experts, the consumption of various psychoactive substances has harmful effects on behavior, health, learning, and family life. School performance and the ability to think and learn decrease. Drug users are dissatisfied with their lives, have problems with social relationships, engage in partner violence, and may develop antisocial behavior in their lives.

RESUMEN

BACKGROUND: Telemedicine has the potential to remove geographic and temporal obstacles to health care access. Whether and how telemedicine can increase health care access for underserved populations remains an open question. To address this issue, we integrated facilitated telemedicine encounters for the management of hepatitis C virus (HCV), a highly prevalent condition among people with opioid use disorder (OUD), into opioid treatment programs (OTPs). In New York State, OTPs are methadone-dispensing centers that provide patient-centered, evidence-based treatment for OUD. We investigated the integration and impact of facilitated telemedicine into OTP workflows in these settings. OBJECTIVE: This study aims to understand OTP staff experiences with integrating facilitated telemedicine for HCV treatment into OTPs, including best practices and lessons learned. METHODS: We conducted semistructured interviews with 45 OTP staff members (13 clinical, 12 administrative, 6 physicians, and 14 support staff members) at least one year after the implementation of facilitated telemedicine for HCV management. We used hermeneutic phenomenological analysis to understand OTP staff experiences. RESULTS: We identified 4 overarching themes illustrating the successful integration of facilitated telemedicine for HCV care into OTPs. First, integration requires an understanding of the challenges, goals, and values of the OTP. As OTP staff learned about new, highly effective HCV therapies, they valued an HCV cure as a "win" for their patients and were excited about the potential to eliminate a highly prevalent infectious disease. Second, the integration of facilitated telemedicine into OTPs fosters social support and reinforces relationships between patients and OTP staff. OTP staff appreciated the ability to have "eyes on" patients during telemedicine encounters to assess body language, a necessary component of OUD management. Third, participants described high levels of interprofessional collaboration as a care team that included the blurring of lines between disciplines working toward a common goal of improving patient care. Study case managers were integrated into OTP workflows and established communication channels to improve patient outcomes. Fourth, administrators endorsed the sustained and future expansion of facilitated telemedicine to address comorbidities. CONCLUSIONS: OTP staff were highly enthusiastic about facilitated telemedicine for an underserved population. They described high levels of collaboration and integration comparable to relevant integrative frameworks. When situated within OTPs, facilitated telemedicine is a high-value application of telemedicine that provides support for underserved populations necessary for high-quality health care. These experiences support sustaining and scaling facilitated telemedicine in comparable settings and evaluating its ability to address other comorbidities.

RESUMEN

Capacity to consent to treatment of substance use disorders at Ontario's Consent and Capacity Board: A review of past reported decisions.


An Ontario review of legal cases which have considered patients' ability to consent to substance use treatmentsPlain Language SummaryIn general, prescribers must consider whether informed consent was provided prior to starting a treatment. A patient is presumed to be capable to consent to a proposed treatment but could be incapable with respect to any medical treatment. While incapacity is often considered for psychiatric treatments, it could be relevant to substance use treatment like methadone or suboxone, which are also called "Opioid Agonist Therapies" or OAT. OAT is lifesaving and prevents relapse and overdose when a person has an opioid use disorder. If a patient is found incapable of consenting to a treatment, a Substitute Decisions Maker would become the decision maker. In such cases, the patient has the ability to contest or disagree with the finding, and this results in a tribunal hearing at the Consent and Capacity Board in Ontario (CCB). In certain circumstances, the CCB publishes what are known as its Reasons for Decision (RDs), which explain the tribunal's reasoning in coming to a decision in favour of the physician or the person found incapable. This information is publicly searchable. Our methods involved a search of all available CCB RDs in Ontario for search terms related to substance use treatment, such as "methadone". We found that between June 1, 2003 (the date on reporting of RDs began) and June 27, 2023, only 71 RDs involved substance use search terms, out of a total of 10,463 reported RDs. Only one case involved the CCB upholding a finding of incapacity with respect to methadone treatment. These results imply that there are few cases in which the CCB has considered incapacity with respect to substance use treatment, although it is possible that these cases are reported at a lower frequency than other cases.

RESUMEN

Gambling disorder is a severe condition that significantly compromises the lives of those affected. In light of this clinical relevance, the literature on the antecedents of this form of addiction is constant and continually evolving. Consistently with this framework, the present research aimed at investigating the role of some risk factors in gambling disorder, with a specific focus on alexithymia, dissociation, and locus of control. The research involved a sample of 290 participants (183 males and 107 females; Mage = 34.43, SD = 14.65) who practice gambling at least occasionally. They completed an online survey including the South Oaks Gambling Screen, Twenty-Items Toronto Alexithymia Scale, Dissociative Experience Scale-II, and Locus of Control of Behavior. ANOVA and a moderated-mediation model were implemented to analyse the collected data. Results showed that 19.0% of the participants were At Risk and Problem Gamblers, while 27.6% fell into the category of Problematic Gamblers. Problematic Gamblers showed significantly higher levels of alexithymia, dissociation, and external locus of control. Moreover, a significant association between alexithymia and the severity of problematic gambling behaviour was found and was significantly mediated by absorption (a dissociation feature). Furthermore, the external locus of control significantly moderated this indirect effect. The role of gender as a covariate was also investigated. Such findings may offer further insights into the field of clinical research on gambling disorder and may provide useful information for effective clinical practice.

RESUMEN

BACKGROUND: The incidence of behavioral addictions (BAs) associated with scientific and technological advances has been increasing steadily. Unfortunately, a large number of studies on the structural and functional abnormalities have shown poor reproducibility, and it remains unclear whether different addictive behaviors share common underlying abnormalities. Therefore, our objective was to conduct a quantitative meta-analysis of different behavioral addictions to provide evidence-based evidence of common structural and functional changes. METHODS: We conducted systematic searches in PubMed, Web of Science and Scopus from January 2010 to December 2023, supplementing reference lists of high-quality relevant meta-analyses and reviews, to identify eligible voxel-based morphometry (VBM) and functional magnetic resonance imaging (fMRI) studies. Using anisotropic seed-based D-Mapping (AES-SDM) meta-analysis methods, we compared brain abnormalities between BAs and healthy controls (HCs). RESULTS: There were 11 GMV studies (287 BAs and 292 HCs) and 26 fMRI studies (577 BAs and 545 HCs) that met inclusion criteria. Compared with HCs, BAs demonstrated significant reductions in gray matter volume (GMV) in (1) right anterior cingulate gyri extending into the adjacent superior frontal gyrus, as well as in the left inferior frontal gyrus and right striatum. (2) the bilateral precuneus, right supramarginal gyrus, and right fusiform gyrus were hyperfunction; (3) the left medial cingulate gyrus extended to the superior frontal gyrus, the left inferior frontal gyrus, and right middle temporal gyrus had hypofunction. CONCLUSIONS: Our study identified structural and functional impairments in brain regions involved in executive control, cognitive function, visual memory, and reward-driven behavior in BAs. Notably, fronto-cingulate regions may serve as common biomarkers of BAs.

RESUMEN

Similar to addictive substances, addictive behaviours such as gambling and gaming are associated with maladaptive modulation of key brain areas and functional networks implicated in learning and memory. Therefore, this review sought to understand how different learning and memory processes relate to behavioural addictions and to unravel their underlying neural mechanisms. Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we systematically searched four databases - PsycINFO, PubMed, Scopus, and Web of Science using the agreed-upon search string. Findings suggest altered executive function-dependent learning processes and enhanced habit learning in behavioural addiction. Whereas the relationship between working memory and behavioural addiction is influenced by addiction type, working memory aspect, and task nature. Additionally, long-term memory is incoherent in individuals with addictive behaviours. Consistently, neurophysiological evidence indicates alterations in brain areas and networks implicated in learning and memory processes in behavioural addictions. Overall, the present review argues that, like substance use disorders, alteration in learning and memory processes may underlie the development and maintenance of behavioural addictions.
