RESUMEN

INTRODUCTION: This research aims to understand the content and nature, and to explore the harm potential, of suspected 3,4-methylenedioxymethamphetamine (MDMA) substances circulating at music festivals in New South Wales. METHODS: Across 19 music festivals held between October 2019 and March 2020, 302 substances detected and suspected by police to contain MDMA were selected for quantitative analysis. RESULTS: Five percent of substances contained a drug other than MDMA (n = 13) or no drug (n = 2). The remaining 95.0% (n = 287) contained MDMA. Of this sub-sample, capsule was the commonest form (83.3%), followed by tablet (7.7%), crystal (6.3%) and powder (2.8%). The median MDMA base-purity of non-tablet forms ranged between 73.5% and 75.0%. The median MDMA base-dose per tablet (116 mg) was higher than per capsule (68 mg). The dose range varied substantially for capsules (14-146 mg) and tablets (24-201 mg). A higher dose (130 mg or greater) was found in 3.5% of MDMA tablets or capsules. Adulterants were identified in 14.1% of MDMA substances but only 1.6% contained a psychoactive adulterant and none presented as dangerous due to their nature or low concentration. DISCUSSION AND CONCLUSIONS: Dangerous MDMA adulterants or new psychoactive substances in tablet, capsule, powder or crystal forms (whether misrepresented as MDMA or not) were unlikely to be in circulation during the study period. Harm reduction messaging should inform that a key risk-factor for MDMA-related harm is the high and wide variation of purity and dose across forms. Market changes may have occurred since COVID-19, but continued monitoring will ensure messaging remains current.

RESUMEN

OBJECTIVE: Adulteration, substitution or contamination of illicit substances can have clinically significant implications when other illicit substances are included. Such circumstances can present as clusters of poisonings, including severe toxicity and death following exposure to unexpected illicit substances. We report a cluster of laboratory-confirmed lysergic acid diethylamide (LSD) in a powder that was sold as cocaine and used recreationally. METHODS: The Prescription, Recreational and Illicit Substance Evaluation (PRISE) program established by the New South Wales Ministry of Health includes State-based hospital toxicology services, Poisons Information Centre, Forensic & Analytical Science Service and emergency services to identify clusters of severe and unusual toxicity associated with substance use. PRISE criteria include a known cluster (geographically or situationally related) of people with acute severe toxicity, especially when accompanied by a toxidrome that is inconsistent with the history of exposure. A timely comprehensive drug screen and quantification is performed in eligible cases and the results are related to the clinical features. The need for a public health response is then considered. Four individuals inhaled a white powder that was sold as cocaine and developed severe toxicity that was not consistent with cocaine which prompted transfer to hospital for further management. RESULTS: LSD was confirmed in four subjects, and the concentrations in 3 of the individuals were 0.04-0.06 mg/L which are among the highest reported in the literature. Common clinical features were hallucinations, agitation, vomiting, sedation, hypertension, and mydriasis. One subject required intubation and admission to the intensive care unit, two required overnight admission, and the fourth was discharged following oral diazepam after observation. No subject suffered persistent injury. CONCLUSIONS: A close working relationship between pre-hospital emergency services, hospital-based clinical services, public health authorities, and analytical laboratories appears to be advantageous. Favourable clinical outcomes are observed from LSD poisoning despite high exposures with good supportive care.

RESUMEN

BACKGROUND: A substantial increase in drug-related harm was observed during the 2018-2019 music festival season in New South Wales, Australia, including the deaths of five young people. As part of a rapid public health response, the New South Wales Ministry of Health referred samples from patients with suspected severe drug-related illness for forensic toxicological testing to identify the type and concentration of substances associated with the presentations. METHODS: Cases were identified through a variety of active and passive surveillance systems, and selected consecutively based on indicators of clinical severity. Comprehensive toxicology testing of blood and urine samples was expedited for all cases. Demographic and clinical characteristics were collated, together with quantitative toxicology results. Results were analysed using descriptive statistics. RESULTS: Forty cases from eleven different music festivals were included. The majority of cases (80.0%) were aged 25 years and under. There were five fatalities, and 62.5% of cases were admitted to intensive care units. MDMA was the most frequent substance, detected in 87.5% of cases. In 82.9% of cases with MDMA, blood concentrations were above thresholds that have been associated with toxicity. Multiple substances were detected in 60.0% of cases. Novel psychoactive substances were not detected. CONCLUSIONS: Our findings strongly suggest that MDMA-related toxicity was a major factor in the severity of the clinical presentations among these cases. Other substances may have enhanced MDMA toxicity but appear unlikely to have caused severe toxicity in isolation. These findings have important implications for harm reduction strategies targeted to music festival settings.

RESUMEN

BACKGROUND: Bridging the 'gap' between research evidence and the complexities of policy and practice is central to health improvement. The Translational Research Grants Scheme (TRGS) in New South Wales (NSW), Australia, is a funding scheme aimed at reducing the time between research generation and translation to policy and practice. The TRGS is also an important part of NSW Health's efforts to harness and strengthen research capacity to improve health service delivery. METHODS: A document review and interviews (n = 12) with key stakeholders were undertaken following the first round of TRGS funding in November 2016. The communications from continuing quality improvement processes over the three funding rounds have provided further insight. RESULTS AND DISCUSSION: A total of 53 projects have been funded under the scheme, with recipients across many NSW Health organisations. NSW Health has committed more than $24 million to date. Round one of the TRGS was received well by the policy makers, Local Health Districts and research stakeholders interviewed. Of particular note were: the requirement for Chief Executives to demonstrate strong support for the implementation of findings; requirements to partner with state-wide policy leads and clinical networks; and capacity-building outcomes of the scheme. The ongoing quality improvement processes indicate that the program continues to be well received, with improvements to partnership arrangements, and an acknowledgement of the challenge that arises because the scheme, by nature of its capacity-building aim, attracts proposals from a range of research experience. LESSONS LEARNT: The TRGS is filling an important gap in the research funding landscape in NSW and is well regarded by stakeholders. To ensure that the TRGS is achieving its intended aims, an evaluation of the impact of the scheme will take place during 2018-19.

RESUMEN

BACKGROUND: Older adults with visual loss have high rates of depression, restricted participation and reduced quality of life. We sought to measure the impact of lessons in the Alexander technique on vision-related emotional and social well-being, as secondary outcomes to a study on improving physical functioning in this population. METHODS: This is a single-blind randomised controlled trial. One hundred and twenty community-dwelling adults aged 50 to 90 years with visual impairments were randomised to either 12 Alexander lessons over 12 weeks and usual care or usual care. The Perceived Visual Ability Scale, the Keele Assessment of Participation, the emotional subscale of the Impact of Vision Impairment Profile, the Positive and Negative Affect Scale and the five-item Geriatric Depression Scale were administered at baseline and three and 12 months. Participants were receiving services from Guide Dogs NSW/ACT. RESULTS: None of the validated questionnaires found statistically significant improvements after adjustment for baseline at three or 12 months, although the emotional subscale of the Impact of Vision Impairment approached significance in favour of the intervention group (4.54 points, 95 per cent CI: -0.14 to 9.21, p = 0.06). Depressive symptoms were prevalent and associated with greater impact of visual impairment on emotional well-being (odds ratio: 1.12, 95 per cent CI: 1.07 to 1.17, p < 0.0001). Faster gait, an indicator of general mobility, was associated with less depressive symptoms (odds ratio: 1.27, 95 per cent CI: 1.06 to 1.54, p = 0.01). CONCLUSION: On average, there was no significant impact of weekly lessons in the Alexander technique on social and emotional well-being, although the emotional impact of visual impairment showed a trend toward less distress in the intervention group. Our data found that emotional distress associated with visual impairment influences depressive symptoms but contrary to expectations, the level of social support received was not significant. Additionally, gait speed is a significant predictor of depressive symptoms, suggesting that general mobility is of importance to the well-being of older adults with visual impairments.
