RESUMO

AIMS: The COVID-19 pandemic triggered a demand for vaccines, cures, and the need of related documentation for travel, work and other purposes. Our project aimed to identify the illicit availability of such products across the Dark Web Markets (DWMs). METHODS: A retrospective search for COVID-19 related products was carried out across 118 DWMs since the start of the pandemic (March 2020-October 2021). Data on vendors as well as advertised goods such as asking price, marketplace, listed date were collected and further validated through additional searches on the open web to verify the information relating to specific marketplaces. Both quantitative and qualitative methods were used for data analysis. RESULTS: Forty-two listings of unlicenced COVID-19 cures and vaccination certificates were identified across 8 marketplaces sold by 25 vendors with significant variation in prices. The listings were found to be geographically specific and followed the progression of the pandemic in terms of availability. Correlations between vendor portfolios of COVID-19 products and variety of goods of other illicit nature such as illegal weaponry, medication/drugs of abuse also emerged from our analysis. CONCLUSION: This study is one of the first attempts to identify the availability of unlicenced COVID-19 products on DWMs. The easy accessibility to vaccines, fake test certificates and hypothetical/illegal cures poses serious health risks to (potential) buyers due to the uncontrolled nature of such products. It also exposes buyers to an unwanted contact with vendors selling a variety of other dangerous illicit goods. Further monitoring and regulatory responses should be implemented to protect the health and safety of citizens especially at times of global crisis.

RESUMO

Background: In a time of unprecedented global change, the COVID-19 pandemic has led to a surge in demand of COVID-19 vaccines and related certifications. Mainly due to supply shortages, counterfeit vaccines, fake documentation, and alleged cures to illegal portfolios, have been offered on darkweb marketplaces (DWMs) with important public health consequences. We aimed to profile key DWMs and vendors by presenting some in-depth case studies. Methods: A non-systematic search for COVID-19 products was performed across 118 DWMs. Levels of activity, credibility, content, COVID-19 product listings, privacy protocols were among the features retrieved. Open web fora and other open web sources were also considered for further analysis of both functional and non functional DWMs. Collected data refers to the period between January 2020 and October 2021. Results: A total of 42 relevant listings sold by 24 vendors across eight DWMs were identified. Four of these markets were active and well-established at the time of the study with good levels of credibility. COVID-19 products were listed alongside other marketplace content. Vendors had a trusted profile, communicated in English language and accepted payments in cryptocurrencies (Monero or Bitcoin). Their geographical location included the USA, Asia and Europe. While COVID-19 related goods were mostly available for regional supply, other listings were also shipped worldwide. Interpretation: Findings emerging from this study rise important questions about the health safety of certain DWMs activities and encourage the development of targeted interventions to overcome such new and rapidly expanding public health threats.

RESUMO

Objective: The aim of this pilot trial was to assess the feasibility of ASBI in primary health care units (PHCUs) in Kazakhstan. Methods: A two-arm cluster randomised trial in five PHCUs based on the RE-AIM framework for implementation studies was carried out. Patients with AUDIT-C scores ≥4 for females and ≥5 for males received a brief face-to-face intervention delivered by a trained physician plus information leaflet (intervention group, IG) or simple feedback including a leaflet (control group, CG). Results: Among 7327 patients eligible for alcohol screening according to the inclusion criteria 1148 patients were screened (15.7%, IG: 11.5%, CG: 27.3%). 12.3% (N = 141) were tested AUDIT-C positive (IG: 9.9%, CG: 15.1%). Out of 112 physicians invited, 48 took part in the ASBI training, 31 finally participated in the study, 21 in the IG (2 PHCUs), 10 in the CG (3 PHCUs). The majority of physicians did not have difficulties in performing the intervention. Conclusion: ASBI is feasible and can be implemented into PHC settings in Kazakhstan. However, the implementation depends on the willingness and interest of the PHCU and the physicians.

RESUMO

BACKGROUND: Identifying and addressing heavy drinking represents a major public health priority worldwide. Whilst the majority of alcohol screening and brief intervention (ASBI) research has been conducted in western, high-income countries, evidence is growing that ASBI can also impact positively on heavy drinkers in low- and middle-income country populations. This mixed methods study aims to assess the feasibility of conducting a fully randomised controlled trial of the effectiveness of ASBI in primary care in Kazakhstan and explore the feasibility and acceptability of implementing ASBI in this setting from patients' and physicians' perspectives. METHODS: Six primary health care units in the region of Pavlodar will be cluster randomised to either an intervention (WHO manualised 5 min alcohol brief intervention plus alcohol leaflet) or control group (simple feedback plus alcohol leaflet). Primary feasibility measures will be rates of participation at baseline and retention of eligible patients at the 3-month follow-up point. Patient/physician questionnaires and physician focus groups will assess additional dimensions of feasibility, as well as acceptability, according to the RE-AIM framework: Reach (rates of eligible patients screened/received advice); Effectiveness (change in AUDIT-C score); Adoption (rate/representativeness of participating physicians); Implementation (quality of ASBI/barriers and facilitators to delivery); and Maintenance (potential sustainability of intervention). DISCUSSION: This is the first trial of the feasibility and acceptability of ASBI in Kazakhstan. As the planning and assessment of implementation determinants is based on the RE-AIM framework, the project outcomes will be relevant for the future development, tailoring and implementation of ASBI in Kazakhstan.

RESUMO

Background: Octodrine is the trade name for Dimethylhexylamine (DMHA), a central nervous stimulant that increases the uptake of dopamine and noradrenaline. Originally developed as a nasal decongestant in the 1950's, it has recently been re-introduced on the market as a pre-workout and 'fat-burner' product but its use remains unregulated. Our work provides the first observational cross-sectional analytic study on Octodrine as a new drug trend and its associated harms after a gap spanning seven decades. Methods: A comprehensive multilingual assessment of literature, websites, drug fora and other online resources was carried out with no time restriction in English, German, Russian and Arabic. Keywords included Octodrine's synonyms and chemical isomers. Results: Only five relevant publications emerged from the literature search, with most of the available data on body building websites and fora. Since 2015, Octodrine has been advertised online as "the next big thing" and "the god of stimulants," with captivating marketing strategies directed at athletes and a wider cohort of users. Reported side-effects include hypertension, dyspnoea and hyperthermia. Conclusions: The uncontrolled use of Octodrine, its physiological and psychoactive effects raise serious health implications with possible impact on athletes and doping practices. This new phenomenon needs to be thoroughly studied and monitored.

RESUMO

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.

RESUMO

BACKGROUND: Synthetic Cannabinoids (SC) are the widest and most diffused class of Novel Psychoactive Substances. The short- and long- term health risks associated with the consumption of SC are often unknown to both users and health professionals. This review aims to provide a synthesis of the most recent and relevant insights on the pharmacology, clinical and psychopathological aspects of SC. METHOD: A structured search of two bibliographic databases (PubMed and Scopus) was undertaken according to inclusion/exclusion criteria. The following terms "synthetic cannabinoid*", "synthetic cannabimimetic*", "synthetic cannabis", "synthetic marijuana" and "Spice AND cannabinoid*" were used as search strings. RESULTS: 162 relevant results, mainly published in the past two years were revealed. Most results emerged for the keyword "synthetic cannabinoid*", followed by the combination "Spice* AND "cannabinoid*". Most papers were epidemiological, forensic, toxicologic, or analytical. The results of studies were systematized according their contribution to the comprehension of pharmacological, clinical and psychopathological effects of SC. Fifteen SC-related fatality cases were reviewed according to their histories, pathology and toxicology findings. CONCLUSION: The findings of this review confirm the importance of prompt and reliable information available for health professionals More specific analytic techniques and designed preventive strategies are required to face unprecedented SC challenge.

RESUMO

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.
