A literature criticism is given on methods currently using gas chromatography mass spectrometry (GC-MS) to determine plant cannabinoids (p-CBDs). In this study, trialkylsilylation of seven p-CBDs (including their transformation products formed in the drug user's body) was compared applying various alkylsilyl reagents1 and the mass fragmentation properties of the corresponding derivatives were characterized. Derivatization, mass fragmentation and quantitation related model investigations were optimized as a function of the reaction times and conditions...

Until recently, HIV in Africa was presumed to be driven by poverty, gender inequality and poor governance. The last decade has seen a shift in global and national public health discourses, especially in eastern Africa where new statistical evidence is used to justify prevention efforts to target Key Populations, i.e. men who have sex with men (MSM), injecting drug users, and sex workers. In this article, we focus on Kenya to examine state, NGO and community HIV treatment and prevention efforts targeting MSM, specifically male sex workers...

Existing methods to estimate the prevalence of chronic hepatitis C (HCV) in New York City (NYC) are limited in scope and fail to assess hard-to-reach subpopulations with highest risk such as injecting drug users (IDUs). To address these limitations, we employ a Bayesian multi-parameter evidence synthesis model to systematically combine multiple sources of data, account for bias in certain data sources, and provide unbiased HCV prevalence estimates with associated uncertainty. Our approach improves on previous estimates by explicitly accounting for injecting drug use and including data from high-risk subpopulations such as the incarcerated, and is more inclusive, utilizing ten NYC data sources...

The spaces in which drug use occurs constitutes a key aspect of the "risk environment" of people who inject drugs (PWID). We aimed to add nuance to the characterization of "safe" and "unsafe" spaces in PWID's environments to further understand how these spaces amplify the risk of morbidities associated with injection drug use. PWID were recruited through the Baltimore City syringe service program and through peer referral. Participants completed a socio-behavioral survey. Multivariable logistic regression was used to identify associations between utilization of public, semi-public and private spaces with arrest, non-fatal overdose, and receptive syringe sharing...

INTRODUCTION: Pulmonary intravascular talcosis is a rare condition occurring in intravenous drug users injecting oral medications. Talc results in a foreign-body granulomatous reaction giving a radiological haematogenic miliary appearance mimicking miliary tuberculosis. Drug users represent a population at risk for both these conditions and their distinction may be challenging. CASE REPORT: We reported the case of a man, 33 year-old, intravenous drug addict, detected by the health services because he was the partner of a person who died of contagious and multi-resistant tuberculosis...

Background: Intravenous drug use is associated with progressive kidney disease of several aetiologies. It is associated with behavioural and lifestyle characteristics that make the provision of renal replacement therapies (RRTs) challenging. We observed that patients who use intravenous drugs [people who inject drugs (PWID)] present late to renal services and struggle to engage with treatment. We describe the experience of a UK centre providing renal services to a mixed city and rural population...

BACKGROUND: People who inject drugs (PWIDs) and who are living with HIV and hepatitis C virus (HCV) infection are vulnerable to a range of health-related harms, including liver cirrhosis, hepatocellular carcinoma, and death. There is limited evidence describing how HIV serostatus shapes access to a physician for regular HCV care among PWID. SETTING: Data were collected through the Vancouver Injection Drug Users Study (VIDUS), the AIDS Care Cohort to evaluate Exposure to Survival Services (ACCESS), and the At-Risk Youth Study (ARYS), 3 prospective cohorts involving people who use illicit drugs in Vancouver, Canada, between 2005 and 2015...

Background: Multiple factors are linked to extremely high unintended pregnancy rates among women who use opioids, including various barriers to contraception adherence. These include patient level barriers such as lack of knowledge and education about highly effective contraception, and potential provider barriers. Using a mixed-methods framework to examine the contraception-related perceptions and preferences of opioid using women is a necessary next step to understanding this phenomenon...

INTRODUCTION: Over 2 million people in high-income countries live with HIV. Early diagnosis and treatment present benefits for infected subjects and reduce secondary transmissions. Cost-effectiveness analyses are important to effectively inform policy makers and consequently implement the most cost-effective programmes. Therefore, we conducted a systematic review regarding the cost-effectiveness of HIV screening in high-income countries. METHODS: We followed PRISMA statements and included all papers evaluating the cost-effectiveness of HIV screening in the general population or in specific subgroups...

BACKGROUND: Overdose is a major cause of death among injecting drug users in Wales. Few studies, however, have explored the overdose responses of witnesses in this context. This study applies Rhodes' concept of the 'risk environment' to examine how witnesses respond to opiate overdose. METHOD: In depth, semi-structured interviews were conducted with fifty-five participants recruited from statutory and third sector drug treatment providers operating across South Wales and from two Welsh prisons...

BACKGROUND: The intentional use of illicit drugs for sexual purposes (also known as 'chemsex') is well known within the MSM communities in Malaysia although research in this population is scarce primarily because both drug use and homosexuality are illegal and stigmatised in Malaysia. METHODS: From April to December 2014, interviews were conducted with twenty men (age range 21-43) living in Greater Kuala Lumpur who had sexual intercourse with other men in the past 6 months and who used illicit drugs at least monthly in the past 3 months...

Importance: About 40 000 Americans and 2 million people worldwide are newly infected with HIV each year. The combination antiretroviral regimen, tenofovir disoproxil fumarate (TDF)/emtricitabine, taken as a single pill once daily, has been shown to prevent HIV transmission but is used by fewer than 20% of people who could benefit in the United States. Observations: PubMed was searched on February 15, 2018, using the search terms pre-exposure, prophylaxis, HIV, and PrEP to identify English-language articles published between 2010 and 2018...

BACKGROUND: The first evidence that the hazard ratio (HR) for methadone-specific death rises more steeply with age-group than for all drug-related deaths (DRDs) came from Scotland's cohort of 33,000 methadone-prescription clients. We aim to examine, for England, whether illicit opioid users' risk of methadone-specific death increases with age; and to pool age-related HRs for methadone-specific deaths with those for Scotland's methadone-prescription clients. METHODS: The setting is all services in England that provide publicly-funded, structured treatment for illicit opioid users, the methodology linkage of the English National Drug Treatment Monitoring System and mortality database, and key measurements are DRDs, methadone-specific DRDs, or heroin-specific DRDs, by age-group and gender, with proportional hazards adjustment for substances used, injecting status and periods in/out of treatment...
