OBJECTIVE: Prophylaxis with granulocyte colony-stimulating factors (G-CSFs) is recommended for patients receiving myelosuppressive chemotherapy regimens with a high risk of febrile neutropenia (FN). G-CSFs should be administered starting the day after chemotherapy, necessitating return trips to the oncology clinic at the end of each cycle. We examined the travel burden related to prophylactic G-CSF injections after chemotherapy in the United States (US). METHODS: We used 2012-2014 Medicare claims data to identify a national cohort of beneficiaries age 65+ with non-myeloid cancers who received both chemotherapy and prophylactic G-CSFs...

Until the law in the United Kingdom (UK) changed in May 2016 so called "legal highs" or "new psychoactive substances" were freely available in high street shops across the UK. Following prohibition these drugs are still easily purchased illegally via the internet. We report a case of a patient who self-administered 3-fluorophenmetrazine intravenously with catastrophic consequences. Adverse effects were almost immediate with symptoms of malaise and tachycardia. Two days post administration he was transferred to the intensive therapy unit with acute kidney injury and irreversible four limb ischaemia...

BACKGROUND AND AIMS: In Scotland, Hepatitis B virus (HBV) vaccination for all prisoners was introduced in 1999; here, we examine the impact of this programme among people who inject drugs (PWID) in the community. This study aimed to compare rates of HBV vaccine uptake before and after implementation of the prison programme and to estimate the determinants of vaccine uptake, the levels of ever/current HBV infection and the associations between vaccine uptake and ever/current HBV infection...

"Krokodil" is the street name for a homemade injectable drug that has been used as a cheap substitute for heroin. Codeine is the opioid starting material for krokodil synthesis and desomorphine is the opioid claimed to be the main component of krokodil and the main responsible for its addictive and psychoactive characteristics. However, due to its peculiar manufacture, using cheap raw materials, krokodil is composed by a large and complex mixture of different substances. In order to shed some light upon the chemical complexity of krokodil, its profiling was conducted by reverse phase high performance liquid chromatography coupled to photodiode array detector (RP-HPLC-DAD) and by liquid chromatography coupled to high resolution tandem mass spectrometry (LC-ESI-IT-Orbitrap-MS)...

Gas chromatography thermal-electron ionization mass spectrometry (GC-EI-MS) is an established method for the identification of mind-altering substances and is routinely used by forensic laboratories. However, some commonly analyzed drugs of abuse, relating to the synthetic cannabinoids receptor agonist group (SCs), pose a challenge for this conventional technique. As the molecular cation radicals of many excited SCs are labile within the ion source, the relative abundance of the molecular ions obtained by the GC-EI-MS is often too small to allow discrimination of structurally related drugs...

BACKGROUND: Six recent randomised control trials (RCTs) have suggested that supervised injectable heroin (SIH) can be effective in patients who persist in street heroin use during methadone treatment. However, short-term randomised control trials have limitations in assessing the effectiveness of treatments for addictive disorders, which are chronic and relapsing disorders of motivation. These RCTs particularly fail to capture the process of the SIH treatment and the diversity of influence and change over time...

REVIEW
Alexandra Maas, Burkhard Madea, Cornelius Hess
Confirmation or exclusion of recent heroin consumption is still one of the major challenges for forensic and clinical toxicologists. A great variety of biomarkers is available for heroin abuse confirmation, including various opium alkaloids (e.g. morphine, codeine), street heroin impurities (e.g. 6-acetylcodeine (6-AC), noscapine, papaverine) as well as associated metabolites (e.g. 6-monoacetylmorphine (6-MAM), morphine glucuronides). Though, the presence of most of these biomarkers cannot solely be attributed to a previous heroin administration but can, among other things, also be due to consumption of poppy seed products ('poppy seed defense'), opium preparations or specific medications, respectively...

Acute fulminant liver failure and acute renal failure are devastating complications caused by many drugs. The use of N-acetylcysteine has been well established in acetaminophen toxicity, but it remains controversial in other cases. Dialysis is a very effective method of removing certain drugs from the system. With the invention of new street drugs such as "synthetic marijuana," it may be beneficial in patients whom the substances ingested are unknown. We report a case of a 42-year-old male who developed acute fulminant hepatic failure and acute renal failure, who was cured with dialysis, N-acetylcysteine, and other supportive measures...

The study had the goal to evaluate psychoactive substance use severity, violence, physical and emotional health of crack users who seeks specialized treatment in Psychosocial Care Centers for Alcohol and Drugs (CAPSad) concerning housing status. This is a multicenter cross-sectional study in six Brazilian capitals with 564 crack users categorized into two groups (1) users who have been homeless sometime in life (n = 266) and (2) individuals who have never lived on streets (n = 298). To assess the substance use severity and the characteristics of the individuals, the Addiction Severity Index, 6th version (ASI-6) was used...

Heroin clandestine laboratories have been a feature of the Malaysian illicit drug scene soon after the abuse of heroin emerged in 1972. The first few heroin clandestine laboratories which synthesised heroin via the acetylation of imported morphine were uncovered in 1973 and 1977. By the mid 1980s this type of laboratories was replaced by heroin cutting laboratories whereby imported high grade heroin was cut to street heroin. This was to meet the rising demand for the drug owing to the rapid escalation of the number of drug users...

Intensive sociometric network data were collected from a typical respondent driven sample (RDS) of 528 people who inject drugs residing in Hartford, Connecticut in 2012-2013. This rich dataset enabled us to analyze a large number of unobserved network nodes and ties for the purpose of assessing common assumptions underlying RDS estimators. Results show that several assumptions central to RDS estimators, such as random selection, enrollment probability proportional to degree, and recruitment occurring over recruiter's network ties, were violated...

OBJECTIVE: Nowadays, the web is rapidly spreading, playing a significant role in the marketing or sale or distribution of "quasi" legal drugs, hence facilitating continuous changes in drug scenarios. The easily renewable and anarchic online drug-market is gradually transforming indeed the drug market itself, from a "street" to a "virtual" one, with customers being able to shop with a relative anonymity in a 24-hr marketplace. The hidden "deep web" is facilitating this phenomenon. The paper aims at providing an overview to mental health's and addiction's professionals on current knowledge about prodrug activities on the deep web...

Perceived devaluation has been shown to have adverse effects on the mental and physical health outcomes of people who use drugs. However, the impact of perceived devaluation on sexually transmitted infections (STI) testing uptake among street-involved youth, who face multiple and intersecting stigmas due to their association with drug use and risky sexual practices, has not been fully characterized. Data were obtained between December 2013 and November 2014 from a cohort of street-involved youth who use illicit drugs aged 14-26 in Vancouver, British Columbia...

BACKGROUND: The growing menace of poor quality and falsified drugs constitutes a major hazard, compromising healthcare and patient outcomes. Efforts to assess drug standards worldwide have almost exclusively focused on anti-microbial drugs; with no study to date on cardiovascular drugs. Our study aims to assess quality of seven routinely used cardiovascular medications (anticoagulants, antihypertensives and statins) in ten Sub-Saharan African countries. METHODS: Drugs were prospectively collected using standardized methods between 2012 and 2014 from licensed (random pharmacies) and unlicensed (street-markets) places of sale in Africa...

We investigate the geographic patterns of drug poisoning deaths involving heroin by county for the USA from 2000 to 2014. The county-level patterns of mortality are examined with respect to age-adjusted rates of death for different classes of urbanization and racial and ethnic groups, while rates based on raw counts of drug poisoning deaths involving heroin are estimated for different age groups and by gender. To account for possible underestimations in these rates due to small areas or small numbers, spatial empirical Baye's estimation techniques have been used to smooth the rates of death and alleviate underestimation when analyzing spatial patterns for these different groups...

Cocaine is a naturally occurring and illicitly used psychostimulant drug, which exerts its activity at monoaminergic neurotransmitter transporters. These transporters mediate the reuptake of the monoamines dopamine, serotonin and norepinephrine and are blocked by cocaine. The increase of monoamines in the extracellular space is the phenomenon underlying the drug effects that cocaine users seek. Currently, it is one of the most important illicit drugs on the European market. However, this increase in monoamines is also the underlying cause for the development of addiction and a number of severe side effects...
