RESUMO

BACKGROUND: Harms associated with the use of alcohol and other drugs (AOD) in licensed entertainment settings (LES) and outdoor music festivals (OMF) are ongoing public health and criminal justice concerns. This systematic review provides a comprehensive, synthesized report on the evidence base of interventions that impact harm in these settings, and how they affect health, behavioral, and criminal justice outcomes. METHODS: Nine databases were searched for experimental and observational studies published between 2010 and 2021. Studies were included if they were peer-reviewed, published in English, described interventions which could impact AOD-related harms in LES or OMF (and were delivered in these environments), and reported on health, criminal justice and/or behavioral outcomes. Methodological quality was assessed using the Effective Public Health Practice Project's Quality Assessment Tool for Quantitative Studies and the Critical Appraisal Skills Program for qualitative studies. A narrative synthesis was conducted to synthesize outcomes across studies. The review protocol was registered in PROSPERO (CRD42020140004). RESULTS: Of the 48,303 studies screened, 100 met the inclusion criteria. 86 focused solely on reducing alcohol-related harm, 7 on reducing illicit drug-related harm, and 7 on both. Most (n = 88) focused on LES and evaluated changes in laws and regulations (n = 28) and/or multicomponent interventions/policies (n = 41). Multicomponent interventions showed the best results for both health (62% positive) and criminal justice (84% positive) outcomes, with 71% of studies being rated as strong quality. There was also good evidence to support the careful application of trading hour restrictions and limited but promising evidence to support medical services and drug checking. CONCLUSION: The breadth, quality and volume of evidence regarding what works in reducing AOD-related harm in recreational settings have increased in the past decade, particularly regarding LES. Findings support onsite medical services (reducing ambulance transfer rates), multicomponent interventions targeting alcohol accessibility and availability (reducing assaults), and drug checking services, but suggest other interventions such as drug detection dogs may exacerbate harm. Further, higher quality research is required to address identified gaps in the evidence base, particularly on optimal interventions within OMF, around illicit drugs more broadly and in the Global South.

RESUMO

INTRODUCTION: Hereditary pyropoikilocytosis (HPP) is a heterogeneous inherited disorder of red blood cell (RBC) membrane and cytoskeletal proteins that leads to hemolytic anemia. HPP is characterized by marked poikilocytosis, microspherocytes, RBC fragmentation, and elliptocytes on peripheral blood smear. Mutations in SPTA1 can cause HPP due to a quantitative defect in α-spectrin and can lead to profound fetal anemia and nonimmune hydrops fetalis, which can be managed with intrauterine transfusion. CASE PRESENTATION: We present a case of a 26-year-old G4P2102 woman of Amish-Mennonite ancestry with a pregnancy complicated by fetal homozygosity for an SPTA1 gene variant (SPTA1c.6154delG) as well as severe fetal anemia and hydrops fetalis, which was managed with four intrauterine transfusions between 26 and 30 weeks gestation. Pre-transfusion peripheral smears from fetal blood samples showed RBC morphology consistent with HPP. The neonate had severe hyperbilirubinemia at birth, which has resolved, but remains transfusion-dependent at 6 months of life. DISCUSSION/CONCLUSION: To our knowledge, this is the first report that correlates homozygosity of the SPTA1c.6154delG gene variant with RBC dysmorphology and establishes the diagnosis of HPP.

RESUMO

Background: The available literature on intrauterine transfusion focuses largely on its application in fetal alloimmunization rather than hereditary red cell disorders, with limited illustration of its associated histopathologic findings. Case report: We present the histologic findings in a placenta associated with preterm delivery of an infant with autosomal SPTA1 mutation following multiple intrauterine transfusions, including appropriate villous maturation, subchorionic organizing hematomas, hemosiderin-laden macrophages, and dysmorphic fetal erythrocytes within villous capillaries. Conclusion: Intrauterine transfusion is associated with placental histologic findings that reflect procedural changes without significant disruption of placental membranes or villous maturation.

RESUMO

Background: DICER1 tumor predisposition syndrome is characterized by an increased risk for development of pleuropulmonary blastoma, pituitary blastoma, multinodular thyroid goiter, thyroid carcinoma, sex cord stromal tumor, cystic nephroma, embryonal rhabdomyosarcoma, and tumors of the CNS, amongst others. Of this list, only pituitary blastoma is recognized as pathognomonic for the syndrome. Case report: We describe a 15-year-old female with bilateral, asynchronous Sertoli-Leydig cell tumors (SLCT). Both tumors harbored an identical germline frameshift mutation as well as unique somatic DICER1 hot-spot point mutations. Discussion: A review of bilateral SLCTs demonstrates that all patients with available DICER1 mutation status carried a germline DICER1 mutation (100%, 9 of 9). In cases with known somatic DICER1 status on bilateral tumors, all harbored distinct somatic mutations (100%, 5 of 5). Our findings support the notion that bilateral ovarian SLCTs are indeed separate events and do not represent recurrent or metastatic disease.

RESUMO

Infantile/congenital fibrosarcoma (IFS) is the most common soft tissue tumor in children less than one year of age. The most common anatomic site of IFS is in the extremities or trunk, and rarely in the abdomen or retroperitoneum. Approximately 70-90% of cases are characterized by a distinct t(12;15)(p13;q25) translocation resulting in an ETV6-NTRK3 gene fusion. As such, TRK inhibitors are considered frontline therapy in TRK-fusion positive IFS. The ETV6-NTRK3 fusion is also detected in congenital mesoblastic nephroma (CMN) and less frequently in myeloid leukemias, secretory breast carcinoma, and mammary-type secretory carcinoma of the skin and salivary glands. Infrequently, cases of tumors with IFS-like morphology without the characteristic ETV6-NTRK3 gene fusion have been identified. Herein, an ETV6-NTRK3 fusion negative spindle cell sarcoma with IFS-like morphology subjected to genomic profiling revealed a PDE10A-BRAF fusion, a fusion event that has been detected previously in an isolated case of undifferentiated infantile sarcoma.

RESUMO

BACKGROUND: Drug law enforcement subsumes the majority of drug policy expenditure across the globe. Fuelled by knowledge that much of this investment is ineffective or counter-productive there have been increasing calls for cross-national comparisons to identify where policing approaches differ and what types of approaches may be more effective. Yet, to date cross-national comparison of drug law enforcement has proven a methodologically hazardous affair. Using a new drug policing module added to the 2017 Global Drug Survey, this study seeks to provide the first cross-national comparison of the incidence, nature and intensity of illicit drug-related police encounters amongst people who use drugs. METHODS: The Global Drug Survey was administered in late 2016. Across 26 countries including Australia, Germany, Italy, Mexico, Switzerland, the UK and the USA a total of 45,942 people who had recently used drugs completed the drug policing module. Key variables assessed included the incidence and frequency of drug-related police encounters in the last 12 months that involved: a) being stopped and searched; b) encountering a drug detection dog; c) being given a caution or warning; d) being charged and arrested; and e) paying a bribe. Multi-level models were used to control for pre-existing national differences in drug use prevalence and non-drug specific policing (including the total number of police personnel in each country). RESULTS: Drug-related police encounters were most commonly reported in Italy and Scotland. Conversely, police encounters were most likely to lead to arrest in Norway, Finland and Sweden. The type and locations of encounters further differed across countries, with for example stop and search most reported in Greece and Colombia, and encounters with drug detection dogs most reported in Scotland, Italy, UK and Australia. Multi-level models showed that the incidence of reported policing encounters continued to differ significantly across countries after controlling for pre-existing national differences in drug use prevalence and policing, and that drug policing encounters were 4 to 14 times more common in some nations than others. CONCLUSION: The findings unearth significant cross-national differences in the incidence and nature of drug-related policing of people who use drugs. This suggests that there may be opportunities for countries to learn from each other about how and why they differ, and the potential benefits of switching to lower intensity modes of drug policing.

RESUMO

BACKGROUND: Significant research attention has been given to understanding the processes of drug policy reform. However, there has been surprisingly little analysis of the persistence of policy in the face of opposition and evidence of ineffectiveness. In this article we analysed just such a case - police drug detection dog policy in NSW, Australia. We sought to identify factors which may account for the continuation of this policy, in spite of counter-evidence and concerted advocacy. METHODS: The analysis was conducted using the Advocacy Coalition Framework (ACF). We collated documents relating to NSW drug detection dog policy from 1995 to 2016, including parliamentary records (NSW Parliament Hansard), government and institutional reports, legislation, police procedures, books, media, and academic publications. Texts were then read, coded and classified against the core dimensions of the ACF, including subsystem actors and coalitions, their belief systems and resources and venues employed for policy debate. RESULTS: Three coalitions were identified as competing in the policy subsystem: security/law and order, civil liberties and harm reduction. Factors that aided policy stability were the continued dominance of the security/law and order coalition since they introduced the drug dog policy; a power imbalance enabling the ruling coalition to limit when and where the policy was discussed; and a highly adversarial policy subsystem. In this context even technical knowledge that dogs infringed civil liberties and increased risks of overdose were readily downplayed, leading to only incremental changes in implementation rather than policy cessation or wholesale revision. CONCLUSION: The analysis provides new insights into why the accumulation of new evidence and advocacy efforts can be insufficient to drive significant policy change. It poses a challenge for the evidence-based paradigm suggesting that in highly adversarial policy subsystems new evidence is unlikely to generate policy change without broader subsystem change, such as reducing the adversarial nature and/or providing new avenues for cross-coalition learning.

RESUMO

BACKGROUND: Variations in drug laws, as well as variations in enforcement practice, exist across jurisdictions. This study explored the feasibility of categorising drug laws "on the books" in terms of their punitiveness, and the extent of their concordance with "laws in practice" in a cross-national comparison. METHODS: "Law on the books", classified with respect to both cannabis and other drug offences in the Czech Republic, NSW (AU) and Florida (USA) were analysed in order to establish an ordinal relationship between the three states. Indicators to assess the "laws in practice" covered both police (arrests) and court (sentencing) activity between 2002 and 2013. Parametric and non-parametric tests of equality of means, tests of stationarity and correlation analysis were used to examine the concordance between the ordinal categorisation of "laws on the books" and "laws in practice", as well as trends over time. RESULTS: The Czech Republic had the most lenient drug laws; Florida had the most punitive and NSW was in-between. Examining the indicators of "laws in practice", we found that the population adjusted number of individuals sentenced to prison ranked across the three states was concordant with categorisation of "laws on the books", but the average sentence length and percentage of court cases sentenced to prison were not. Also, the de jure decriminalisation of drug possession in the Czech Republic yielded a far greater share of administrative offenses than the de facto decriminalisation of cannabis use / possession in NSW. Finally, the mean value of most "laws in practice" indicators changed significantly over time although the "laws on the books" didn't change. CONCLUSIONS: While some indicators of "laws in practice" were concordant with the ordinal categorisation of drug laws, several indicators of "laws in practice" appeared to operate independently from the drug laws as stated. This has significant implications for drug policy analysis and means that research should not assume they are interchangeable and should consider each separately when designing research.

RESUMO

INTRODUCTION AND AIMS: Legal thresholds for drug trafficking, over which possession of an illicit drug is deemed 'trafficking' as opposed to 'personal use', are employed in all Australian states and territories excepting Queensland. In this paper, we explore the extent to which people who regularly inject drugs understand such laws. DESIGN AND METHODS: Participants from the seven affected states/territories in the 2012 Illicit Drug Reporting System (n = 823) were asked about their legal knowledge of trafficking thresholds: whether, if arrested, quantity possessed would affect legal action taken; and the quantities of heroin, methamphetamine, cocaine and cannabis that would constitute an offence of supply. Data were compared against the actual laws to identify the accuracy of knowledge by drug type and state, and sociodemographics, use and purchasing patterns related to knowledge. RESULTS: Most Illicit Drug Reporting System participants (77%) correctly said that quantity possessed would affect charge received. However, only 55.8% nominated any specific quantity that would constitute an offence of supply, and of those 22.6% nominated a wrong quantity, namely a quantity that was larger than the actual quantity for supply (this varied by state and drug). DISCUSSION AND CONCLUSIONS: People who regularly inject drugs have significant gaps in knowledge about Australian legal thresholds for drug trafficking, particularly regarding the actual threshold quantities. This suggests that there may be a need to improve education for this population. Necessity for accurate knowledge would also be lessened by better design of Australian drug trafficking laws.

RESUMO

INTRODUCTION AND AIMS: Media attention to cocaine use and supply has increased following some of the largest cocaine seizures in Australia's history. Whether there has been an expansion in supply remains unclear. This paper examines the evidence behind assertions of increased supply in Australia and the scale and nature of any apparent increase, using proxy indicators of cocaine importation, distribution and use. DESIGN AND METHODS: Eight proxies of cocaine importation, distribution and use were adopted, including amount of importation, mode of importation and supply flows to Australia. Each proxy indicator was sourced using publicly available and Australia-wide data, including information on the total weight of border seizures, mode of detection and country of embarkation of individual seizures. Data permitting, trends were examined for up to a 12 year period (1997-1998 to 2009-2010). RESULTS: Since 2006-2007 there was evidence of increased cocaine importation, albeit less than between 1998-1999 and 2001-2002. There were further signs that the 2006-2007 expansion coincided with a diversification of trafficking routes to and through Australia (beyond the traditional site of entry-Sydney) and shifts in the geographic distribution of use. DISCUSSION AND CONCLUSIONS: The congruity between indicators suggests that there has been a recent expansion in cocaine supply to and distribution within Australia, but that the more notable shift has concerned the nature of supply, with an apparent growth in importation and distribution beyond New South Wales. The diversification of cocaine supply routes may increase risks of market entrenchment and organised crime throughout Australia.

RESUMO

ISSUES: Illicit drugs are never far from the media gaze and although identified almost a decade ago as 'a new battleground' for the alcohol and other drug (AOD) field there has been limited research examining the role of the news media and its effects on audiences and policy. APPROACH: This paper draws together media theories from communication literature to examine media functions. We illustrate how each function is relevant for media and drugs research by drawing upon the existing literature examining Australian media coverage during the late 1990s of escalating heroin-related problems and proposed solutions. KEY FINDINGS: Media can influence audiences in four key ways: by setting the agenda and defining public interest; framing issues through selection and salience; indirectly shaping individual and community attitudes towards risk; and feeding into political debate and decision making. Each has relevance for the AOD field. For example, media coverage of the escalating heroin-related problems in Australia played a strong role in generating interest in heroin overdoses, framing public discourse in terms of a health and/or criminal issue and affecting political decisions. Implications AND CONCLUSION: Media coverage in relation to illicit drugs can have multifarious effects. Incorporating media communication theories into future research and actions is critical to facilitate understanding of the short- and long-term impacts of media coverage on illicit drugs and the avenues by which the AOD field can mitigate or inform future media debates on illicit drugs.

RESUMO

ISSUES: Evidence-based policy is promoted as the ideal in drug policy, yet public policy theorists suggest that policy-based evidence may be a more fitting analogy, where evidence is used selectively to support a predetermined policy direction. The following paper assesses the resonance of this notion to the development of the Illicit Drug Diversion Initiative (IDDI), an apparently pragmatic reform adopted in Australia in 1999 through the Federal Coalition 'Tough on Drugs' strategy. It utilises interviews with key informants from the Australian drug policy arena conducted in 2005 to assess the role of evidence in the design and implementation of the IDDI. KEY FINDINGS: The current paper shows that while policy-makers were generally supportive of the IDDI and viewed drug diversion as a more pragmatic response to drug users, they contend that implementation has suffered through a selective and variable emphasis upon evidence. Most notably, the IDDI is not premised upon best-practice objectives of reducing harm from drug use, but instead on 'Tough on Drugs' objectives of reducing drug use and crime. IMPLICATIONS: This paper contends that policy-based evidence may facilitate the adoption of pragmatic reforms, but reduce the capacity for effective reform. It therefore has both functional and dysfunctional elements. The paper concludes that greater attention is needed to understanding how to mesh political and pragmatic objectives, and hence to maximise the benefits from policy-based evidence.
