(Re)introducing medicinal cannabis.

• After considering extensive scientific and medical evidence, a New South Wales Legislative Council multiparty committee recommended that medicinal cannabis should lawfully be made available for selected-use pharmacotherapy. • The evidence indicates that cannabis has genuine medicinal utility in patients with certain neuropathic conditions, with acceptable levels of risk from mostly mild side effects. • The potential medical benefits of cannabis pharmacotherapy have largely been overlooked, with research and society's attention, in most parts of the world, being directed towards the hazards of its recreational use. • The NSW Government has since dismissed the unanimous and compassionate recommendations of their committee.

Heroin use impairs smoking cessation among Australian prisoners.

BACKGROUND: Prisoners have extremely high rates of smoking with rates 3-4 times higher than the general community. Many prisoners have used heroin. The aims of this study were to investigate the impact of heroin use on smoking cessation and the social determinants of health among prisoners. METHODS: Secondary analysis of data from a randomised controlled trial of a multi-component smoking cessation intervention involving 425 Australian male prisoners. Inmates who, prior to imprisonment, used heroin regularly were compared to those who did not use heroin regularly. Self-reported smoking status was validated at baseline and each follow-up by measuring carbon monoxide levels. Readings exceeding 10 ppm were defined as indicating current smoking. RESULTS: Over half (56.5%) of the participants had ever used heroin while 37.7% regularly (daily or almost daily) used heroin in the year prior to entering prison. Prisoners who regularly used heroin had significantly worse social determinants of health and smoking behaviours, including lower educational attainment, more frequent incarceration and earlier initiation into smoking. Prisoners who regularly used heroin also used and injected other drugs significantly more frequently. At 12-month follow-up, the smoking cessation of prisoners who had regularly used heroin was also significantly lower than prisoners who did not regularly use heroin, a finding confirmed by logistic regression. CONCLUSIONS: Regular heroin use prior to imprisonment is an important risk factor for unsuccessful attempts to quit smoking among prisoners and is also associated with worse social determinants of health, higher drug use, and worse smoking behaviours. More effective and earlier smoking cessation interventions are required for particularly disadvantaged groups.

Recommendation by a law body to ban infant male circumcision has serious worldwide implications for pediatric practice and human rights.

BACKGROUND: Recent attempts in the USA and Europe to ban the circumcision of male children have been unsuccessful. Of current concern is a report by the Tasmanian Law Reform Institute (TLRI) recommending that non-therapeutic circumcision be prohibited, with parents and doctors risking criminal sanctions except where the parents have strong religious and ethnic ties to circumcision. The acceptance of this recommendation would create a precedent for legislation elsewhere in the world, thereby posing a threat to pediatric practice, parental responsibilities and freedoms, and public health. DISCUSSION: The TLRI report ignores the scientific consensus within medical literature about circumcision. It contains legal and ethical arguments that are seriously flawed. Dispassionate ethical arguments and the United Nations Convention on the Rights of the Child are consistent with parents being permitted to authorize circumcision for their male child. Uncritical acceptance of the TLRI report's recommendations would strengthen and legitimize efforts to ban childhood male circumcision not just in Australia, but in other countries as well. The medical profession should be concerned about any attempt to criminalize a well-accepted and evidence-based medical procedure. The recommendations are illogical, pose potential dangers and seem unworkable in practice. There is no explanation of how the State could impose criminal charges against doctors and parents, nor of how such a punitive apparatus could be structured, nor how strength of ethnic or religious ties could be determined. The proposal could easily be used inappropriately, and discriminates against parents not tied to the religions specified. With time, religious exemptions could subsequently be overturned. The law, governments and the medical profession should reject the TLRI recommendations, especially since the recent affirmative infant male circumcision policy statement by the American Academy of Pediatrics attests to the significant individual and public health benefits and low risk of infant male circumcision. SUMMARY: Doctors should be allowed to perform medical procedures based on sound evidence of effectiveness and safety with guaranteed protection. Parents should be free to act in the best interests of the health of their infant son by having him circumcised should they choose.

Evidence-based circumcision policy for Australia.

The aim was (1) to perform an up-to-date systematic review of the male circumcision (MC) literature and (2) to determine the number of adverse medical conditions prevented by early MC in Australia. Searches of PubMed using "circumcision" with 39 keywords and bibliography searches yielded 278 publications meeting our inclusion criteria. Early MC provides immediate and lifetime benefits, including protection against: urinary tract infections, phimosis, inflammatory skin conditions, inferior penile hygiene, candidiasis, various STIs, and penile and prostate cancer. In female partners MC reduces risk of STIs and cervical cancer. A risk-benefit analysis found benefits exceeded procedural risks, which are predominantly minor, by approximately 200 to 1. It was estimated that more than 1 in 2 uncircumcised males will experience an adverse foreskin-related medical condition over their lifetime. An increase in early MC in Australia to mid-1950s prevalence of 85% from the current level of 18.75% would avoid 77,000 cases of infections and other adverse medical conditions over the lifetime for each annual birth cohort. Survey data, physiological measurements, and the anatomical location of penile sensory receptors responsible for sexual sensation indicate that MC has no detrimental effect on sexual function, sensitivity or pleasure. US studies found that early infant MC is cost saving. Evidence-based reviews by the AAP and CDC support early MC as a desirable public health measure. Although MC can be performed at any age, early MC maximizes benefits and minimises procedural risks. Parents should routinely be provided with accurate, up-to-date evidence-based information in an unbiased manner early in a pregnancy so that they have time to weigh benefits and risks of early MC and make an informed decision should they have a son. Parental choice should be respected. A well-trained competent practitioner is essential and local anaesthesia should be routinely used. Third party coverage of costs is advocated.

Cardiovascular risk among Aboriginal and non-Aboriginal smoking male prisoners: inequalities compared to the wider community.

BACKGROUND: Cardiovascular risk factors (CVRF) were collected as part of a randomised controlled trial of a multi-component intervention to reduce smoking among male prisoners. Cross-sectional baseline data on CVRF were compared among smoking male prisoners and males of similar age in the general population. METHODS: 425 smoking prisoners were recruited (n = 407 in New South Wales; 18 in Queensland), including 15% of Aboriginal descent (mean age 33 years; median sentence length 3.6 years). We measured CVRF such as smoking, physical activity, blood pressure, risky alcohol use, symptoms of depression, and low socioeconomic status. RESULTS: We found that 39% of prisoners had 3+ CVRF, compared to 10% in a general community sample of most disadvantaged men of a similar age. Significantly more Aboriginal prisoners had 3+ CVRF than non-Aboriginal prisoners (55% vs 36%, p < 0.01) and were twice as likely to have 4+ CVRF (27% vs 12%). In addition to all prisoners in this study being a current smoker (with 70% smoking 20+ cigarettes per day), the prevalence of other CVRF was very high: insufficient physical activity (23%); hypertension (4%), risky drinking (52%), symptoms of depression (14%) and low socioeconomic status (SES) (44%). Aboriginal prisoners had higher levels of risky alcohol use, symptoms of depression, and were more likely to be of low SES. CONCLUSION: Prisoners are at high risk for developing cardiovascular disease compared to even the most disadvantaged in their community and should be the focus of specific public health interventions.

Early infant male circumcision: Systematic review, risk-benefit analysis, and progress in policy.

AIM: To determine whether recent evidence-based United States policies on male circumcision (MC) apply to comparable Anglophone countries, Australia and New Zealand. METHODS: Articles in 2005 through 2015 were retrieved from PubMed using the keyword "circumcision" together with 36 relevant subtopics. A further PubMed search was performed for articles published in 2016. Searches of the EMBASE and Cochrane databases did not yield additional citable articles. Articles were assessed for quality and those rated 2+ and above according to the Scottish Intercollegiate Grading System were studied further. The most relevant and representative of the topic were included. Bibliographies were examined to retrieve further key references. Randomized controlled trials, recent high quality systematic reviews or meta-analyses (level 1++ or 1+ evidence) were prioritized for inclusion. A risk-benefit analysis of articles rated for quality was performed. For efficiency and reliability, recent randomized controlled trials, meta-analyses, high quality systematic reviews and large well-designed studies were used if available. Internet searches were conducted for other relevant information, including policies and Australian data on claims under Medicare for MC. RESULTS: Evidence-based policy statements by the American Academy of Pediatrics (AAP) and the Centers for Disease Control and Prevention (CDC) support infant and later age male circumcision (MC) as a desirable public health measure. Our systematic review of relevant literature over the past decade yielded 140 journal articles that met our inclusion criteria. Together, these showed that early infant MC confers immediate and lifelong benefits by protecting against urinary tract infections having potential adverse long-term renal effects, phimosis that causes difficult and painful erections and "ballooning" during urination, inflammatory skin conditions, inferior penile hygiene, candidiasis, various sexually transmissible infections in both sexes, genital ulcers, and penile, prostate and cervical cancer. Our risk-benefit analysis showed that benefits exceeded procedural risks, which are predominantly minor, by up to 200 to 1. We estimated that more than 1 in 2 uncircumcised males will experience an adverse foreskin-related medical condition over their lifetime. Wide-ranging evidence from surveys, physiological measurements, and the anatomical location of penile sensory receptors responsible for sexual sensation strongly and consistently suggested that MC has no detrimental effect on sexual function, sensitivity or pleasure. United States studies showed that early infant MC is cost saving. The evidence supporting early infant MC has further strengthened since the positive AAP and CDC reviews. CONCLUSION: Affirmative MC policies are needed in Australia and New Zealand. Routine provision of accurate, unbiased education, and access in public hospitals, will maximize health and financial benefits.

Hair analysis underestimates heroin use in prisoners.

The value of hair analysis in measuring treatment outcome was examined in a randomised controlled trial (RCT) of an Australian state prison-based methadone programme between 1997 and 1998 (n = 382 male prisoners). Hair samples were analysed for morphine using immunoassay techniques. Agreement between hair analysis and self-report was tested using kappa, McNemar's test of symmetry and Pearson's correlation coefficient r. Hair analysis based on immunoassay was inadequate as the primary outcome measure for the RCT but had value in supplementing self-reported heroin use. There was a modest correlation (r = 0.31, p < 0.001) between self-reported frequency of heroin use and morphine concentrations in hair. Sectional hair analysis, a reflection of duration of drug use, was uninformative and generally impractical due to the length of hair sections needed.

Smoking and its correlates in an Australian prisoner population.

Despite evidence of high rates of smoking among prisoners, there has been limited research that describes smoking patterns and risk factors associated with smoking in this group. This study describes inmate smokers and identifies factors associated with smoking in prison, using a survey comprising a cross-sectional random sample of inmates stratified by sex, age and Aboriginality. A total of 914 adult inmates (747 men, 167 women) were recruited from 29 New South Wales (Australia) correctional centres. Information on the prevalence of smoking, smoking history, smoking behaviours and other risk factors were collected. Of the participants, 79% were current smokers (78% men, 83% women). Younger inmates were more likely than older inmates to smoke (86% vs. 64%). Most individuals smoked between 11 and 20 cigarettes a day and a median of 50 grams per week. In the previous year, over half (52%) of current smokers had attempted to quit or reduce the amount they smoked. At the time of the survey, 58% of smokers had plans to quit; 21% within 3 months. Independent predictors of current smoking in the multivariate analysis were past use of cannabis and a history of illicit drug use. The prevalence of smoking in prison is extraordinarily high and exceeds that of the general community. Despite this, the majority of prisoners report plans to quit. Readily available smoking cessation advice, support and treatment are needed to assist those wanting to quit in this stressful environment. As the prevalence of smoking within the general community declines, assisting cessation in groups containing a disproportionate number of smokers will become increasingly important. Despite high levels of tobacco dependence, many prisoners intend to quit and health planners and custodial authorities need to encourage and support inmates who do attempt to quit.

Four-year follow-up of imprisoned male heroin users and methadone treatment: mortality, re-incarceration and hepatitis C infection.

AIMS: To examine the long-term impact of methadone maintenance treatment (MMT) on mortality, re-incarceration and hepatitis C seroconversion in imprisoned male heroin users. DESIGN, SETTING AND PARTICIPANTS: The study cohort comprised 382 imprisoned male heroin users who had participated in a randomized controlled trial of prison-based MMT in 1997/98. Subjects were followed-up between 1998 and 2002 either in the general community or in prison. MEASUREMENTS: All-cause mortality, re-incarceration, hepatitis C and HIV serostatus and MMT retention. FINDINGS: There were no deaths recorded while subjects were enrolled in MMT. Seventeen subjects died while out of MMT, representing an untreated mortality rate of 2.0 per 100 person-years (95% CI, 1.2-3.2). Re-incarceration risk was lowest during MMT episodes of 8 months or longer (adjusted hazard ratio 0.3 (95% CI, 0.2-0.5; P < 0.001), although MMT periods 2 months or less were associated with greatest risk of re-incarceration (P < 0.001). Increased risk of hepatitis C seroconversion was significantly associated with prison sentences of less than 2 months [adjusted hazard ratio 20 (95% CI, 5-76; < P = 0.001)] and MMT episodes less than 5 months [adjusted hazard ratio 4.2 (95% CI, 1.4-12.6; P = 0.01)]. Subjects were at greatest risk of MMT dropout during short prison sentences of 1 month or less (adjusted hazard ratio 10.4 (95% CI, 7.0-15.7; P < 0.001). HIV incidence was 0.3 per 100 person-years (95% CI, 0.03-0.99). CONCLUSIONS: Retention in MMT was associated with reduced mortality, re-incarceration rates and hepatitis C infection. Prison-based MMT programmes are integral to the continuity of treatment needed to ensure optimal outcomes for individual and public health.
