RESUMEN

INTRODUCTION: Despite being a widely used screening questionnaire, there is no consensus on the most appropriate measurement model for the Alcohol Use Disorders Identification Test (AUDIT). Furthermore, there have been limited studies on its measurement invariance across cross-cultural subgroups, genders, and sexual orientations. AIMS: The present study aimed to examine the fit of different measurement models for the AUDIT and its measurement invariance across a wide range of subgroups by country, language, gender, and sexual orientation. METHODS: Responses concerning past-year alcohol use from the participants of the cross-sectional International Sex Survey were considered (N = 62,943; Mage: 32.73; SD = 12.59). Confirmatory factor analysis, as well as measurement invariance tests were performed for 21 countries, 14 languages, three genders, and four sexual-orientation subgroups that met the minimum sample size requirement for inclusion in these analyses. RESULTS: A two-factor model with factors describing 'alcohol use' (items 1-3) and 'alcohol problems' (items 4-10) showed the best model fit across countries, languages, genders, and sexual orientations. For the former two, scalar and latent mean levels of invariance were reached considering different criteria. For gender and sexual orientation, a latent mean level of invariance was reached. CONCLUSIONS: In line with the two-factor model, the calculation of separate alcohol-use and alcohol-problem scores is recommended when using the AUDIT. The high levels of measurement invariance achieved for the AUDIT support its use in cross-cultural research, capable also of meaningful comparisons among genders and sexual orientations.

RESUMEN

Interactions between childhood trauma (CT) and dissociation can contribute to psychiatric disturbances. We explored this phenomenon in relation to behavioral addictions (BAs) in a sample (n = 633) of young adults (age: 18-34 years). Self-report measures investigating CT, dissociation, and symptoms related to gambling disorder, internet gaming disorder, problematic social media use, exercise dependence and compulsive buying were used. Scales related to BAs were summarized into a single measure ("Total Behavioral Addiction Index" - TBAI) for inferential analyses. A model analyzing the direct and indirect effects of CT on TBAI through the mediation of pathological dissociation was performed, controlling for confounding factors. Measures on CT, dissociation, and TBAI were significantly associated with each other (all p < .001). The total effect of CT on TBAI was significant (B = 0.063; CI: 0.045; 0.081); pathological dissociation significantly mediated such association (B = 0.023; CI: 0.013; 0.036). Our findings support the possibility that the interaction between CT and dissociation contributes to increase disturbances related to BAs.

RESUMEN

PURPOSE: Studies have shown significant associations of dissociative symptoms with both eating and addictive disorders; however, the different forms of dissociation have been relatively understudied in relation to food addiction (FA). The main aim of this study was to investigate the association of certain forms of dissociative experiences (i.e., absorption, detachment and compartmentalization) with FA symptoms in a nonclinical sample. METHODS: Participants (N = 755; 543 women; age range: 18-65; mean age: 28.22 ± 9.99 years) were evaluated using self-report measures of FA, dissociation, eating disturbances, and general psychopathology. RESULTS: Compartmentalization experiences (defined as pathological over-segregation of higher mental functions) were independently associated with FA symptoms (ß = 0.174; p = 0.013; CI = [0.008; 0.064]) even when confounding factors were controlled for. CONCLUSION: This finding suggests that compartmentalization symptoms can have a role in the conceptualization of FA, with such two phenomena possibly sharing common pathogenic processes. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.

RESUMEN

INTRODUCTION: Kratom (Mitragyna speciosa) is a tropical plant traditionally used as an ethnomedicinal remedy for several conditions in South East Asia. Despite the increased interest in its therapeutical benefits in Western countries, little scientific evidence is available to support such claims, and existing data remain limited to kratom's chronic consumption. OBJECTIVE: Our study aims to investigate (pre)clinical evidence on the efficacy of kratom as a therapeutic aid and its safety profile in humans. METHODS: A systematic literature search using PubMed and the Medline database was conducted between April and November 2020. RESULTS: Both preclinical (N = 57) and clinical (N = 18) studies emerged from our search. Preclinical data indicated a therapeutic value in terms of acute/chronic pain (N = 23), morphine/ethanol withdrawal, and dependence (N = 14), among other medical conditions (N = 26). Clinical data included interventional studies (N = 2) reporting reduced pain sensitivity, and observational studies (N = 9) describing the association between kratom's chronic (daily/frequent) use and safety issues, in terms of health consequences (e.g., learning impairment, high cholesterol level, dependence/withdrawal). CONCLUSIONS: Although the initial (pre)clinical evidence on kratom's therapeutic potential and its safety profile in humans is encouraging, further validation in large, controlled clinical trials is required.

RESUMEN

With the onset of the COVID-19 pandemic and the accelerated spread of the SARS-CoV-2 virus came jurisdictional limitations on mobility of citizens and distinct alterations in their daily routines. Confined to their homes, many people increased their overall internet use, with problematic use of the internet (PUI) becoming a potential reason for increased mental health concerns. Our narrative review summarizes information on the extent of PUI during the pandemic, by focusing on three types: online gaming, gambling and pornography viewing. We conclude by providing guidance for mental health professionals and those affected by PUI (with an outline of immediate research priorities and best therapeutic approaches), as well as for the general public (with an overview of safe and preventative practices).

RESUMEN

Global concern about problematic usage of the internet (PUI), and its public health and societal costs, continues to grow, sharpened in focus under the privations of the COVID-19 pandemic. This narrative review reports the expert opinions of members of the largest international network of researchers on PUI in the framework of the European Cooperation in Science and Technology (COST) Action (CA 16207), on the scientific progress made and the critical knowledge gaps remaining to be filled as the term of the Action reaches its conclusion. A key advance has been achieving consensus on the clinical definition of various forms of PUI. Based on the overarching public health principles of protecting individuals and the public from harm and promoting the highest attainable standard of health, the World Health Organisation has introduced several new structured diagnoses into the ICD-11, including gambling disorder, gaming disorder, compulsive sexual behaviour disorder, and other unspecified or specified disorders due to addictive behaviours, alongside naming online activity as a diagnostic specifier. These definitions provide for the first time a sound platform for developing systematic networked research into various forms of PUI at global scale. Progress has also been made in areas such as refining and simplifying some of the available assessment instruments, clarifying the underpinning brain-based and social determinants, and building more empirically based etiological models, as a basis for therapeutic intervention, alongside public engagement initiatives. However, important gaps in our knowledge remain to be tackled. Principal among these include a better understanding of the course and evolution of the PUI-related problems, across different age groups, genders and other specific vulnerable groups, reliable methods for early identification of individuals at risk (before PUI becomes disordered), efficacious preventative and therapeutic interventions and ethical health and social policy changes that adequately safeguard human digital rights. The paper concludes with recommendations for achievable research goals, based on longitudinal analysis of a large multinational cohort co-designed with public stakeholders.

RESUMEN

Background: Kratom (Mitragyna speciosa Korth.) use outside of Southeast Asia has increased over the past decade. Objectives: This investigation clarifies kratom's role in perceived well-being, overall health, and temporal correlation with drug use to understand kratom's role in the self-treatment of substance use disorders (SUDs). Methods: Between July 2019 and July 2020 an anonymous, cross-sectional, online survey was taken by 7,381 people who use kratom (PWUK) recruited through social media and other online resources. This included an assessment of (a) the relationship between self-reported overall health, concomitant use of drugs of misuse, and demographics; (b) the perceived effectiveness of kratom in self-treating diagnosed health conditions or symptoms; (c) the profile of PWUK primarily for drug dependence, pain, and mood or mental health conditions based on demographics. Results: A total of 5,152 valid responses (45.9% females/53.7% males) were collected. Kratom was primarily used for self-treating pain (73.0%) and improving emotional or mental health conditions (42.2%) without clinical supervision. Those with a SUD (synthetic opioids, methadone, benzodiazepines, or heroin) used kratom after discontinuing illicit or other drugs (94.8%). The primary substances taken before or concomitantly with kratom were cannabis, cannabidiol, benzodiazepines, or kava. PWUKs report a dose-dependent benefit for alleviating pain and relieving negative moods. Adverse effects were primarily gastrointestinal, typically at high (>5 g/dose) and frequent (>22 doses/week) dosing. Conclusions: Kratom was primarily used as a harm-reduction agent for SUDs and self-treatment of chronic conditions. Healthcare professionals need better information about kratom, its potential adverse effects, and clinically significant drug interactions.

RESUMEN

One of the worrying concomitants of problematic use of Internet (PUI) is aggression. Although the mechanisms underlying such link have not been completely clarified, it has been suggested that problematic use of social media and online videogames (i.e., two common forms of PUI among young adults) lead to increased sleep disturbances which, in turn, represent a relevant trigger for aggression. We have tested this hypothesis in a sample (N = 480) of young individuals (351 females and 129 males; mean age: 21.76 ± 1.92 years; range: 18-24). Self-report measures investigating symptoms related to social media addiction (SMA), Internet gaming disorder (IGD), insomnia severity, and aggression were used. Mediational models analyzing the direct and indirect associations of SMA- and IGD-related symptoms on aggression severity through insomnia-related symptoms were performed controlling for confounding factors. The models showed that the total effects of SMA-related symptoms (B = 0.018; p = .010) and of IGD-related symptoms (B = 0.018; p = .041) on aggression severity were significant and that these associations were mediated by insomnia-related symptoms (respectively, p < .001 and p = .003). Our findings support the potential mediating role of insomnia severity in the association of SMA- and IGD-related disturbances with levels of aggression.

RESUMEN

PURPOSE: Although the association between problematic use of the internet and eating disorders (EDs) in young adults has been previously established, its underlying mechanisms have not been completely clarified. It has been suggested that exposure to idealized very thin and toned body images (e.g., "thinspiration" and "fitspiration" trends) on social media might lead to increased feelings of body dissatisfaction which, in turn, can represent a trigger for EDs. We have tested this hypothesis in a sample (N = 721) of young adults (504 females, mean age: 24.13 ± 3.70 years; range 18-34). METHODS: Self-report measures investigating symptoms related to social media addiction (SMA), muscle dysmorphia (MD), and EDs were used. A mediational model analyzing the direct and indirect effects of SMA-related symptoms on ED-related symptoms through the mediating role of MD-related symptoms was performed controlling for confounding factors (e.g., socio-demographic variables, substances use, body mass index, psychopathological distress). RESULTS: The model showed that the total effect of SMA-related symptoms on ED-related symptoms was significant (B = 0.213; p = 0.022) and that this association was mediated by MD-related symptoms (B = 0.083; p = 0.021). DISCUSSION: Our findings support the possibility that MD-related symptoms play a relevant role in mediating the association between SMA severity and ED pathology. LEVEL OF EVIDENCE: Level III, evidence obtained from well-designed cohort or case-control analytic studies.

RESUMEN

As a response to the COVID-19 pandemic, many governments have introduced steps such as spatial distancing and "staying at home" to curb its spread and impact. The fear resulting from the disease, the 'lockdown' situation, high levels of uncertainty regarding the future, and financial insecurity raise the level of stress, anxiety, and depression experienced by people all around the world. Psychoactive substances and other reinforcing behaviors (e.g., gambling, video gaming, watching pornography) are often used to reduce stress and anxiety and/or to alleviate depressed mood. The tendency to use such substances and engage in such behaviors in an excessive manner as putative coping strategies in crises like the COVID-19 pandemic is considerable. Moreover, the importance of information and communications technology (ICT) is even higher in the present crisis than usual. ICT has been crucial in keeping parts of the economy going, allowing large groups of people to work and study from home, enhancing social connectedness, providing greatly needed entertainment, etc. Although for the vast majority ICT use is adaptive and should not be pathologized, a subgroup of vulnerable individuals are at risk of developing problematic usage patterns. The present consensus guidance discusses these risks and makes some practical recommendations that may help diminish them.

RESUMEN

Novel psychoactive substance (NPS) availability is increasing at a phenomenal rate and so is their associated misuse. Currently, the harms associated with NPS misuse are unclear. This report presents the initial findings of a continuing study looking into the impact of NPS misuse on admissions to an acute mental health facility in London. Violence preadmission and violence during admission have been found to be significant in NPS misusers compared to non-NPS substance misusers. Our findings have important consequences for acute mental health, emergency, and public health services. NPS misusers require specific assessment and risk management to reduce the risk of violence towards others.

RESUMEN

OBJECTIVE: The aim of the study was to prospectively assess whether regular use of synthetic cannabinoids (SCs) affects the duration of opioid-related withdrawal and craving symptoms in patients undergoing drug detoxification treatments. METHODS: Patients (n = 193) with opioid use disorder, among which 47 patients are regularly using SCs, underwent integrated drug detoxification therapies. The Clinical Opiate Withdrawal Scale and a specific visual analogue scale were used to assess opioid withdrawal and craving symptoms over time. RESULTS: Subjects using SCs had significantly longer duration of withdrawal and craving symptoms (p < .001). Higher intake of SCs in the last 30 days (p = .045), shorter time since the last intake of SCs (p = .033), longer duration of SCs use (p < .001), and higher dosage of SCs (p < .001) were associated with longer duration of symptoms. DISCUSSION: This is the first study to assess the impact of SCs on the course of opioid withdrawal and craving symptoms. The results (a) suggest that patients with opioid use disorder in combination with regular use of SCs exhibit a significantly longer duration of opioid withdrawal and craving symptoms, (b) add to the accumulating evidence showing clinical and molecular cross talks between cannabinoids and opioids, and (c) underline novel harmful effects of SCs.

RESUMEN

OBJECTIVE: Kratom (Mitragyna speciosa. Korth) is an indigenous medicinal plant of Southeast Asia. This review paper aims to describe the trends of kratom use in Southeast Asia. DESIGN: A literature review search was conducted through ScienceDirect, Scopus, ProMed and Google Scholar. Twenty-five articles illustrating kratom use in humans in Southeast Asia were reviewed. RESULTS: Kratom has long been used by rural populations in Southeast Asia as a remedy for common ailments, to fight fatigue from hard manual work, as a drink during social interaction among men, and in village religious functions. Studies based on self-reports suggest that prolonged kratom use does not result in serious health risks or impair social functioning. Two recent trends have also emerged: (a) Kratom is reportedly being used to ease withdrawal from opioid dependence in rural settings; whereas (b) in urban areas, adulterated kratom cocktails are being consumed by younger people to induce euphoria. CONCLUSIONS: Legal sanctions appear to have preceded serious scientific investigations into the claimed benefits of ketum. More objective-controlled trials and experiments on humans need to be conducted to validate self-report claims by kratom users in the community.

RESUMEN

OBJECTIVE: The strive for perfection is prevalent in the fitness industry. This study aimed to explore the use of products to enhance performance alongside exposure to exercise addiction, appearance anxiety and self-esteem in fitness settings. METHODS: An online survey was prepared and piloted before wider dissemination in fitness clubs via snowballing and selected mailing lists. A list of commonly used products, including Performance and Image Enhancing Drugs (PIEDs) was provided. Exercise addiction (Exercise Addiction Inventory; EAI), anxiety levels (Appearance Anxiety Inventory; AAI) and their self-esteem (Rosenberg's Self-Esteem Scale; RSE) were also measured. RESULTS: 377 questionnaires were completed. A significant number of participants declared the use products either to lose weight (16%) or to reach their fitness goals (41%). The Internet played a major role in both the supply of information and the provision of the enhancement products (33.7%) and side effects were reported (10.5%). Only a limited number of participants sought a medical opinion about taking products (5.1%). EAI scores were high (m=20.02 ± 4.1), AAI (m=15.98 ± 4.8) showed an intermediate level of anxiety, while self-esteem was low (RSE m=12.59 ± 2.2). CONCLUSION: This pilot study identified the emergence of a new drug trend in fitness settings and showed a potential relationship to exercise addiction, anxiety disorders and low self-esteem. The Internet played a crucial role in disseminating often untested products, including PIEDs without medical supervision and unwanted side-effects were reported. More studies in the field are required in order to safeguard public health and inform policy making.

RESUMEN

BACKGROUND: The diffusion of novel psychoactive substances (NPSs), combined with the ability of the Internet to act as an online marketplace, has led to unprecedented challenges for governments, health agencies, and substance misuse services. Despite increasing research, there is a paucity of reliable information available to professionals working in the field. The paper will present the pilot results of the first mobile application (SMAIL) for rapid information sharing on NPSs among health professionals. METHODS: The development of SMAIL was divided into 2 parts: (a) the creation of the application for registered users, enabling them to send an SMS or email with the name or "street name" of an NPS and receive within seconds emails or SMS with the information, when available and (b) the development of a database to support the incoming requests. RESULTS: One hundred twenty-two professionals based in 22 countries used the service over the pilot period of 16 months (from May 2012 to September 2013). Five hundred fifty-seven enquires were made. Users received rapid information on NPSs, and 61% of them rated the service as excellent. CONCLUSIONS: This is the right time to use mobile phone technologies for rapid information sharing and prevention activities on NPSs.

RESUMEN

BACKGROUND: Hair analysis for illicit substances is widely used to detect chronic drug consumption or abstention from drugs. Testees are increasingly seeking ways to avoid detection by using a variety of untested adulterant products (e.g., shampoos, cleansers) widely sold online. This study aims to investigate adulteration of hair samples and to assess effectiveness of such methods. METHODS: The literature on hair test evasion was searched for on PubMed or MEDLINE, Psycinfo, and Google Scholar. Given the sparse nature of peer-reviewed data on this subject, results were integrated with a qualitative assessment of online sources, including user-orientated information or commercial websites, drug fora and "chat rooms". Over four million web sources were identified in a Google search by using "beat hair drug test" and the first 86 were monitored on regular basis and considered for further analysis. RESULTS: Attempts to influence hair test results are widespread. Various "shampoos," and "cleansers" among other products, were found for sale, which claim to remove analytes. Often advertised with aggressive marketing strategies, which include discounts, testimonials, and unsupported claims of efficacy. However, these products may pose serious health hazards and are also potentially toxic. In addition, many anecdotal reports suggest that Novel Psychoactive Substances are also consumed as an evasion technique, as these are not easily detectable via standard drug test. Recent changes on Novel Psychoactive Substances legislations such as New Psychoactive Bill in the UK might further challenge the testing process. CONCLUSION: Further research is needed by way of chemical analysis and trial of the adulterant products sold online and their effects as well as the development of more sophisticated hair testing techniques.

RESUMEN

BACKGROUND: Fenetheylline, a psychostimulant drug, often branded as Captagon, is a combination of amphetamine and theophylline. Since the cessation of its legal production in 1986, counterfeited products have been produced illicitly in south-east Europe and far-east Asia. Its profitable trade has been linked to terrorist organizations, including Islamic State of Iraq and the Levant. This study aims to reach up-to-date data, concerning the Captagon e-commerce and use in the Middle East. METHODS: A multi-staged and multi-lingual literature search was carried out. A list of prespecified keywords was applied across medical and paramedical databases, web and Dark web, search engines, social communication media, electronic commerce websites, media networks, and the Global Public Health Intelligence Network database. RESULTS: The use of Captagon as a stimulant in terrorist settings has been marginally covered in the literature. Data can widely be retrieved from Google and AOL search engines, YouTube, and Amazon e-commerce websites, and to a lesser extent from Alibaba and eBay. On the contrary, Middle Eastern e-commerce websites yielded almost no results. Interestingly, the Dark web generated original data for Captagon e-commerce in the Middle East. CONCLUSION: Further investigations are needed on the role that psychoactive drugs play in terrorist attacks and civil war zones. Unless a comprehensive methodological strategy, inclusive of unconventional methods of research, is implemented, it will not be feasible to face such a threat to humanity.

RESUMEN

OBJECTIVE: To determine the feasibility and utility of using media reports and other open-source information collected by the Global Public Health Intelligence Network (GPHIN), an event-based surveillance system operated by the Public Health Agency of Canada, to rapidly detect clusters of adverse drug events associated with 'novel psychoactive substances' (NPS) at the international level. METHODS AND RESULTS: Researchers searched English media reports collected by the GPHIN between 1997 and 2013 for references to synthetic cannabinoids. They screened the resulting reports for relevance and content (i.e., reports of morbidity and arrest), plotted and compared with other available indicators (e.g., US poison control center exposures). The pattern of results from the analysis of GPHIN reports resembled the pattern seen from the other indicators. CONCLUSIONS: The results of this study indicate that using media and other open-source information can help monitor the presence, usage, local policy, law enforcement responses, and spread of NPS in a rapid effective way. Further, modifying GPHIN to actively track NPS would be relatively inexpensive to implement and would be highly complementary to current national and international monitoring efforts.

RESUMEN

OBJECTIVES: The intravenous (IV) injection of tropicamide for non-clinical purposes is a new and widespread drug trend. The aim of this study is to provide the first literature review on the topic. METHODS: Relevant literature was identified through a search of MEDLINE, Psycinfo, Google Scholar, conference proceedings and select citations. RESULTS: Cases of tropicamide (IV) injection have been reported in Russia, Italy, Turkey and Kazakhstan. This phenomenon is mainly secondary to primary opioid (especially heroin) addiction. Several key factors can be associated with its rapid diffusion: (i) enhancement of the 'positive' effects of heroin; (ii) decrease and delay of heroin withdrawal symptoms; (iii) easy availability; (iv) low costs; (v) fast effects; and (vi) visibility of self-reported experiences on Internet. Acute tropicamide intoxications can lead to anticholinergic syndrome, hyperthermia, tremors and convulsions. Chronic tropicamide-related problems include cardiovascular toxicity, psychosis, renal or liver failures, severe weight loss and infections. Fatalities due to tropicamide IV injection have been reported in non evidence-based/peer-reviewed sources, such as drug fora, websites and media news. CONCLUSIONS: Tropicamide IV injections represent a serious health risk. Specific prevention programmes should be implemented for the general population as well as for the high-risk population of polydrug abusers.

RESUMEN

OBJECTIVE: In recent years, increasing intravenous mephedrone use was reported in several countries. The aim of this study was to describe the characteristics of such a form of mephedrone use, while identifying the differences between injectors and non-injectors in patterns of mephedrone use and psychiatric symptom status. METHODS: One hundred and forty-five mephedrone users were surveyed on patterns of mephedrone use using a structured questionnaire as well as the Brief Symptom Inventory. RESULTS: Majority of users received mephedrone from acquaintances and used it in discos/parties settings regarding both first and current mephedrone use. Intranasal use was the most typical route of administration (84.4%). Injectors (11%) used the drug more frequently and in higher dosages. This group included a greater proportion of opiate users (37.5%) and showed more diffuse psychiatric symptoms. Regarding the predictors of being an injector, heroin use showed the highest odds ratio. CONCLUSIONS: Intravenous mephedrone use is associated with a higher risk of harmful drug use, elevated psychiatric symptom profile and increased possibility of mephedrone being considered as an addictive substance. These findings might be important in efficient treatment planning.
