Drug use and risk behaviours among injecting drug users: a comparison between sex workers and non-sex workers in Sydney, Australia
BACKGROUND: This paper examines the differences in demographics, drug use patterns and self reported risk behaviours between regular injecting drug users (IDU) who report engaging in sex work for money or drugs and regular injecting drug users who do not. METHODS: Cross sectional data collected from regular IDU interviewed as part of the New South Wales (NSW) Illicit Drug Reporting System (IDRS) in 2003 were analysed. RESULTS: IDU who reported engaging in sex work were more likely to be female, and identify as being of Aboriginal and/or Torres Strait Islander descent. They initiated injecting drug use at a significantly younger age and were more likely to report injection related problems than IDU who had not engaged in sex work. There were no differences in the drug classes used, but findings suggested that the sex workers tended to be more frequent users of crystalline methamphetamine (ice) and benzodiazepines. CONCLUSION: The similarities between these groups were more striking than the differences. Further research, examining a larger sample is needed to clarify whether injecting drug users who are sex workers have heavier use patterns
Trends and characteristics of accidental and intentional codeine overdose deaths in Australia
Examines trends in codeine-related mortality rates in Australia, and the clinical and toxicological characteristics of codeine-related deaths.
Abstract
Objectives: To examine trends in codeine-related mortality rates in Australia, and the clinical and toxicological characteristics of codeine-related deaths.
Design and setting: Analysis of prospectively collected data from the National Coronial Information System on deaths where codeine toxicity was determined to be an underlying or contributory cause of death. The study period was 2000–2013.
Main outcome measures: Population-adjusted numbers (per million persons) of (1) codeine-related deaths, classified by intent (accidental or intentional); and (2) heroin- and Schedule 8 opioid-related deaths (as a comparator).
Results: The overall rate of codeine-related deaths increased from 3.5 per million in 2000 to 8.7 per million in 2009. Deaths attributed to accidental overdoses were more common (48.8%) than intentional deaths (34.7%), and their proportion increased during the study period. High rates of prior comorbid mental health (53.6%), substance use (36.1%) and chronic pain (35.8%) problems were recorded for these deaths. For every two Schedule 8 opioid-related deaths in 2009, there was one codeine-related death. Most codeine-related deaths (83.7%) were the result of multiple drug toxicity.
Conclusions: Codeine-related deaths (with and without other drug toxicity) are increasing as the consumption of codeine-based products increases. Educational messages are needed to better inform the public about the potential harms of chronic codeine use, especially in the context of polypharmacy
Drugs and the internet.
Key findings:
The number of retailers on the Silk Road increased (from 282 at time 1 to 374 at the last time point), while the number of retailers on the surface web remained relatively stable (92 at time 1 and 101 at the last time point). The increase on the Silk Road is largely driven by international rather than domestic retailers.
• On the Silk Road, cannabis and EPS were sold by the largest number of retailers consistently across all time points, followed by MDMA (3,4-methylenedioxy-Nmethylamphetamine) and pharmaceuticals (primarily benzodiazepines and sildenafil).
• The type of EPS available from surface web retailers differed substantially from the EPS available from those selling on the Silk Road. EPS sold on the Silk Road more closely mirrored those most commonly used by EDRS participants (i.e. people who regularly use psychostimulants) including drugs from the 2C-x and NBOMe categories, followed by DMT (dimethyltryptamine), Mephedrone and Methylone.
• Average prices of methamphetamine, cocaine and ecstasy being sold on the Silk Road remained stable across the time period. Average domestic prices for common quantities of these substances were comparable to prices paid for these same quantities by 2012 EDRS participants. Average international prices for these substances were substantially lower
Trends in MDMA-related mortality across four countries
Aims To determine trends in 3,4 methylenedioxymethamphetamine (MDMA)-related death rates across Australia, Finland, Portugal and Turkey and to analyse the toxicology and causes of death across countries. Design Analysis of MDMA-related deaths extracted from a national coronial database in Australia (2001-19) and national forensic toxicology databases in Finland (2001-17), Portugal (2008-19) and Turkey (2007-17). Presentation of MDMA use and seizure data (market indicators). Setting Australia, Finland, Portugal and Turkey. Cases All deaths in which MDMA was considered by the forensic pathologist to be contributory to death. Measurements Information collected on cause and circumstances of death, demographics and toxicology. Findings A total of 1400 MDMA-related deaths were identified in Turkey, 507 in Australia, 100 in Finland and 45 in Portugal. The median age ranged from 24 to 27.5 years, and males represented between 81 and 94% of the deaths across countries. Standardized mortality rates significantly increased across all four countries from 2011 to 2017 during a period of increased purity and availability of MDMA. The underlying cause of death was predominantly due to drug toxicity in Australia (n = 309, 61%), Finland (n = 70, 70%) and Turkey (n = 840, 60%) and other causes in Portugal (n = 25, 56%). Minorities of all deaths across the countries were due to MDMA toxicity alone (13-25%). These deaths had a significantly higher blood MDMA concentration than multiple drug toxicity deaths in Australia, Finland and Turkey. Drugs other than MDMA commonly detected were stimulants (including cocaine, amphetamine and methamphetamine) (Australia 52% and Finland 61%) and alcohol (Australia 46% and Portugal 49%). In addition to MDMA toxicity, benzodiazepines (81%) and opioids (64%) were commonly identified in these deaths in Finland. In comparison, synthetic cannabinoids (15%) and cannabis (33%) were present in a minority of deaths in Turkey. Conclusions Deaths related to 3,4 methylenedioxymethamphetamine (MDMA) increased in Australia, Finland, Portugal and Turkey between 2011 and 2017. Findings show MDMA toxicity alone can be fatal, but multiple drug toxicity remains more prevalent.Peer reviewe

Posttraumatic stress disorder among female street-based sex workers in the greater Sydney area, Australia
BACKGROUND: This paper examines rates of exposure to work-related violence and other trauma, and the prevalence of lifetime and current posttraumatic stress disorder (PTSD) among female street-based sex workers. It also investigates associations between current PTSD symptoms and: demographic characteristics, psychiatric comorbidity, injecting and sex risk behaviours, and trauma history. METHODS: Cross sectional data collected from 72 women via face to face structured interviews. The interview included structured diagnostic assessment of DSM-IV PTSD; drug dependence; depression; experience of childhood trauma; and an assessment of sex working history. RESULTS: All but one of the women interviewed reported experiencing trauma, with the majority reporting multiple traumas that typically began in early childhood. Child sexual abuse, adult sexual assault and work related violence were commonly reported. Just under half of the women met DSM-IV criteria for PTSD and approximately one-third reported current PTSD symptoms. Adult sexual assault was associated with current PTSD symptoms. Depression and drug dependence were also highly prevalent; cocaine dependence in particular was associated with elevated rates of injecting risk and sexual risk behaviours. CONCLUSION: These women reported complex trauma histories and despite ongoing opportunities for clinical intervention, they continued to experience problems, suggesting that current models of treatment may not be appropriate. More targeted interventions, and integrated mental health and drug treatment services are needed to address the problems these women are experiencing. Outreach services to these women remain a priority. Education strategies to reduce risky injecting and sexual behaviours among sex workers should also remain a priority
Ten-year mortality, disease progression, and treatment-related side effects in men with localised prostate cancer from the ProtecT randomised controlled trial according to treatment received
Background
The ProtecT trial reported intention-to-treat analysis of men with localised prostate cancer randomly allocated to active monitoring (AM), radical prostatectomy, and external beam radiotherapy.
Objective
To report outcomes according to treatment received in men in randomised and treatment choice cohorts.
Design, setting, and participants
This study focuses on secondary care. Men with clinically localised prostate cancer at one of nine UK centres were invited to participate in the treatment trial comparing AM, radical prostatectomy, and radiotherapy.
Intervention
Two cohorts included 1643 men who agreed to be randomised and 997 who declined randomisation and chose treatment.
Outcome measurements and statistical analysis
Analysis was carried out to assess mortality, metastasis and progression and health-related quality of life impacts on urinary, bowel, and sexual function using patient-reported outcome measures. Analysis was based on comparisons between groups defined by treatment received for both randomised and treatment choice cohorts in turn, with pooled estimates of intervention effect obtained using meta-analysis. Differences were estimated with adjustment for known prognostic factors using propensity scores.
Results and limitations
According to treatment received, more men receiving AM died of PCa (AM 1.85%, surgery 0.67%, radiotherapy 0.73%), whilst this difference remained consistent with chance in the randomised cohort (p = 0.08); stronger evidence was found in the exploratory analyses (randomised plus choice cohort) when AM was compared with the combined radical treatment group (p = 0.003). There was also strong evidence that metastasis (AM 5.6%, surgery 2.4%, radiotherapy 2.7%) and disease progression (AM 20.35%, surgery 5.87%, radiotherapy 6.62%) were more common in the AM group. Compared with AM, there were higher risks of sexual dysfunction (95% at 6 mo) and urinary incontinence (55% at 6 mo) after surgery, and of sexual dysfunction (88% at 6 mo) and bowel dysfunction (5% at 6 mo) after radiotherapy. The key limitations are the potential for bias when comparing groups defined by treatment received and changes in the protocol for AM during the lengthy follow-up required in trials of screen-detected PCa.
Conclusions
Analyses according to treatment received showed increased rates of disease-related events and lower rates of patient-reported harms in men managed by AM compared with men managed by radical treatment, and stronger evidence of greater PCa mortality in the AM group.
Patient summary
More than 95 out of every 100 men with low or intermediate risk localised prostate cancer do not die of prostate cancer within 10 yr, irrespective of whether treatment is by means of monitoring, surgery, or radiotherapy. Side effects on sexual and bladder function are better after active monitoring, but the risks of spreading of prostate cancer are more common
New Australian guidelines for the treatment of alcohol problems: an overview of recommendations
Summary of recommendations and levels of evidence
Chapter 2: Screening and assessment for unhealthy alcohol use
Screening
Screening for unhealthy alcohol use and appropriate interventions should be implemented in general practice (Level A), hospitals (Level B), emergency departments and community health and welfare settings (Level C).
Quantity–frequency measures can detect consumption that exceeds levels in the current Australian guidelines (Level B).
The Alcohol Use Disorders Identification Test (AUDIT) is the most effective screening tool and is recommended for use in primary care and hospital settings. For screening in the general community, the AUDIT-C is a suitable alternative (Level A).
Indirect biological markers should be used as an adjunct to screening (Level A), and direct measures of alcohol in breath and/or blood can be useful markers of recent use (Level B).
Assessment
Assessment should include evaluation of alcohol use and its effects, physical examination, clinical investigations and collateral history taking (Level C).
Assessment for alcohol-related physical problems, mental health problems and social support should be undertaken routinely (GPP).
Where there are concerns regarding the safety of the patient or others, specialist consultation is recommended (Level C).
Assessment should lead to a clear, mutually acceptable treatment plan which specifies interventions to meet the patient’s needs (Level D).
Sustained abstinence is the optimal outcome for most patients with alcohol dependence (Level C).
Chapter 3: Caring for and managing patients with alcohol problems: interventions, treatments, relapse prevention, aftercare, and long term follow-up
Brief interventions
Brief motivational interviewing interventions are more effective than no treatment for people who consume alcohol at risky levels (Level A).
Their effectiveness compared with standard care or alternative psychosocial interventions varies by treatment setting. They are most effective in primary care settings (Level A).
Psychosocial interventions
Cognitive behaviour therapy should be a first-line psychosocial intervention for alcohol dependence. Its clinical benefit is enhanced when it is combined with pharmacotherapy for alcohol dependence or an additional psychosocial intervention (eg, motivational interviewing) (Level A).
Motivational interviewing is effective in the short term and in patients with less severe alcohol dependence (Level A).
Residential rehabilitation may be of benefit to patients who have moderate-to-severe alcohol dependence and require a structured residential treatment setting (Level D).
Alcohol withdrawal management
Most cases of withdrawal can be managed in an ambulatory setting with appropriate support (Level B).
Tapering diazepam regimens (Level A) with daily staged supply from a pharmacy or clinic are recommended (GPP).
Pharmacotherapies for alcohol dependence
Acamprosate is recommended to help maintain abstinence from alcohol (Level A).
Naltrexone is recommended for prevention of relapse to heavy drinking (Level A).
Disulfiram is only recommended in close supervision settings where patients are motivated for abstinence (Level A).
Some evidence for off-label therapies baclofen and topiramate exists, but their side effect profiles are complex and neither should be a first-line medication (Level B).
Peer support programs
Peer-led support programs such as Alcoholics Anonymous and SMART Recovery are effective at maintaining abstinence or reductions in drinking (Level A).
Relapse prevention, aftercare and long-term follow-up
Return to problematic drinking is common and aftercare should focus on addressing factors that contribute to relapse (GPP).
A harm-minimisation approach should be considered for patients who are unable to reduce their drinking (GPP).
Chapter 4: Providing appropriate treatment and care to people with alcohol problems: a summary for key specific populations
Gender-specific issues
Screen women and men for domestic abuse (Level C).
Consider child protection assessments for caregivers with alcohol use disorder (GPP).
Explore contraceptive options with women of reproductive age who regularly consume alcohol (Level B).
Pregnant and breastfeeding women
Advise pregnant and breastfeeding women that there is no safe level of alcohol consumption (Level B).
Pregnant women who are alcohol dependent should be admitted to hospital for treatment in an appropriate maternity unit that has an addiction specialist (GPP).
Young people
Perform a comprehensive HEEADSSS assessment for young people with alcohol problems (Level B).
Treatment should focus on tangible benefits of reducing drinking through psychotherapy and engagement of family and peer networks (Level B).
Aboriginal and Torres Strait Islander peoples
Collaborate with Aboriginal or Torres Strait Islander health workers, organisations and communities, and seek guidance on patient engagement approaches (GPP).
Use validated screening tools and consider integrated mainstream and Aboriginal or Torres Strait Islander-specific approaches to care (Level B).
Culturally and linguistically diverse groups
Use an appropriate method, such as the “teach-back” technique, to assess the need for language and health literacy support (Level C).
Engage with culture-specific agencies as this can improve treatment access and success (Level C).
Sexually diverse and gender diverse populations
Be mindful that sexually diverse and gender diverse populations experience lower levels of satisfaction, connection and treatment completion (Level C).
Seek to incorporate LGBTQ-specific treatment and agencies (Level C).
Older people
All new patients aged over 50 years should be screened for harmful alcohol use (Level D).
Consider alcohol as a possible cause for older patients presenting with unexplained physical or psychological symptoms (Level D).
Consider shorter acting benzodiazepines for withdrawal management (Level D).
Cognitive impairment
Cognitive impairment may impair engagement with treatment (Level A).
Perform cognitive screening for patients who have alcohol problems and refer them for neuropsychological assessment if significant impairment is suspected (Level A).
Summary of key recommendations and levels of evidence
Chapter 5: Understanding and managing comorbidities for people with alcohol problems: polydrug use and dependence, co-occurring mental disorders, and physical comorbidities
Polydrug use and dependence
Active alcohol use disorder, including dependence, significantly increases the risk of overdose associated with the administration of opioid drugs. Specialist advice is recommended before treatment of people dependent on both alcohol and opioid drugs (GPP).
Older patients requiring management of alcohol withdrawal should have their use of pharmaceutical medications reviewed, given the prevalence of polypharmacy in this age group (GPP).
Smoking cessation can be undertaken in patients with alcohol dependence and/or polydrug use problems; some evidence suggests varenicline may help support reduction of both tobacco and alcohol consumption (Level C).
Co-occurring mental disorders
More intensive interventions are needed for people with comorbid conditions, as this population tends to have more severe problems and carries a worse prognosis than those with single pathology (GPP).
The Kessler Psychological Distress Scale (K10 or K6) is recommended for screening for comorbid mental disorders in people presenting for alcohol use disorders (Level A).
People with alcohol use disorder and comorbid mental disorders should be offered treatment for both disorders; care should be taken to coordinate intervention (Level C).
Physical comorbidities
Patients should be advised that alcohol use has no beneficial health effects. There is no clear risk-free threshold for alcohol intake. The safe dose for alcohol intake is dependent on many factors such as underlying liver disease, comorbidities, age and sex (Level A).
In patients with alcohol use disorder, early recognition of the risk for liver cirrhosis is critical. Patients with cirrhosis should abstain from alcohol and should be offered referral to a hepatologist for liver disease management and to an addiction physician for management of alcohol use disorder (Level A).
Alcohol abstinence reduces the risk of cancer and improves outcomes after a diagnosis of cancer (Level A)
Functional and quality of life outcomes of localised prostate cancer treatments (prostate testing for cancer and treatment [ProtecT] study)
Objective
To investigate the functional and quality of life (QoL) outcomes of treatments for localised prostate cancer and inform treatment decision-making.
Patients and Methods
Men aged 50–69 years diagnosed with localised prostate cancer by prostate-specific antigen testing and biopsies at nine UK centres in the Prostate Testing for Cancer and Treatment (ProtecT) trial were randomised to, or chose one of, three treatments. Of 2565 participants, 1135 men received active monitoring (AM), 750 a radical prostatectomy (RP), 603 external-beam radiotherapy (EBRT) with concurrent androgen-deprivation therapy (ADT) and 77 low-dose-rate brachytherapy (BT, not a randomised treatment). Patient-reported outcome measures (PROMs) completed annually for 6 years were analysed by initial treatment and censored for subsequent treatments. Mixed effects models were adjusted for baseline characteristics using propensity scores.
Results
Treatment-received analyses revealed different impacts of treatments over 6 years. Men remaining on AM experienced gradual declines in sexual and urinary function with age (e.g., increases in erectile dysfunction from 35% of men at baseline to 53% at 6 years and nocturia similarly from 20% to 38%). Radical treatment impacts were immediate and continued over 6 years. After RP, 95% of men reported erectile dysfunction persisting for 85% at 6 years, and after EBRT this was reported by 69% and 74%, respectively (P < 0.001 compared with AM). After RP, 36% of men reported urinary leakage requiring at least 1 pad/day, persisting for 20% at 6 years, compared with no change in men receiving EBRT or AM (P < 0.001). Worse bowel function and bother (e.g., bloody stools 6% at 6 years and faecal incontinence 10%) was experienced by men after EBRT than after RP or AM (P < 0.001) with lesser effects after BT. No treatment affected mental or physical QoL.
Conclusion
Treatment decision-making for localised prostate cancer can be informed by these 6-year functional and QoL outcomes
Adding 6 months of androgen deprivation therapy to postoperative radiotherapy for prostate cancer: a comparison of short-course versus no androgen deprivation therapy in the RADICALS-HD randomised controlled trial
Background
Previous evidence indicates that adjuvant, short-course androgen deprivation therapy (ADT) improves metastasis-free survival when given with primary radiotherapy for intermediate-risk and high-risk localised prostate cancer. However, the value of ADT with postoperative radiotherapy after radical prostatectomy is unclear.
Methods
RADICALS-HD was an international randomised controlled trial to test the efficacy of ADT used in combination with postoperative radiotherapy for prostate cancer. Key eligibility criteria were indication for radiotherapy after radical prostatectomy for prostate cancer, prostate-specific antigen less than 5 ng/mL, absence of metastatic disease, and written consent. Participants were randomly assigned (1:1) to radiotherapy alone (no ADT) or radiotherapy with 6 months of ADT (short-course ADT), using monthly subcutaneous gonadotropin-releasing hormone analogue injections, daily oral bicalutamide monotherapy 150 mg, or monthly subcutaneous degarelix. Randomisation was done centrally through minimisation with a random element, stratified by Gleason score, positive margins, radiotherapy timing, planned radiotherapy schedule, and planned type of ADT, in a computerised system. The allocated treatment was not masked. The primary outcome measure was metastasis-free survival, defined as distant metastasis arising from prostate cancer or death from any cause. Standard survival analysis methods were used, accounting for randomisation stratification factors. The trial had 80% power with two-sided α of 5% to detect an absolute increase in 10-year metastasis-free survival from 80% to 86% (hazard ratio [HR] 0·67). Analyses followed the intention-to-treat principle. The trial is registered with the ISRCTN registry, ISRCTN40814031, and ClinicalTrials.gov, NCT00541047.
Findings
Between Nov 22, 2007, and June 29, 2015, 1480 patients (median age 66 years [IQR 61–69]) were randomly assigned to receive no ADT (n=737) or short-course ADT (n=743) in addition to postoperative radiotherapy at 121 centres in Canada, Denmark, Ireland, and the UK. With a median follow-up of 9·0 years (IQR 7·1–10·1), metastasis-free survival events were reported for 268 participants (142 in the no ADT group and 126 in the short-course ADT group; HR 0·886 [95% CI 0·688–1·140], p=0·35). 10-year metastasis-free survival was 79·2% (95% CI 75·4–82·5) in the no ADT group and 80·4% (76·6–83·6) in the short-course ADT group. Toxicity of grade 3 or higher was reported for 121 (17%) of 737 participants in the no ADT group and 100 (14%) of 743 in the short-course ADT group (p=0·15), with no treatment-related deaths.
Interpretation
Metastatic disease is uncommon following postoperative bed radiotherapy after radical prostatectomy. Adding 6 months of ADT to this radiotherapy did not improve metastasis-free survival compared with no ADT. These findings do not support the use of short-course ADT with postoperative radiotherapy in this patient population
