The Quest to Extend Health Services to Vulnerable Substance Users in Rio de Janeiro, Brazil in the Context of an Unfolding Economic Crisis

Assessing oral health of crack users in Brazil: Perceptions and associated factors, findings from a mixed methods study

This study explores associated factors and perceptions of oral health among crack users recruited in open drug scenes in Brazil. A mixed methods approach was used. The quantitative component analysed findings from a large (N = 7381), population-based survey. The outcomes under analysis were 'self-perception of oral health' and 'self-reporting of problems affecting the mouth, teeth and gingiva (gums)'. The qualitative component comprised a focus group, with 12 individuals recruited from a drug treatment clinic. Lower self-perception of oral health problems vis-à-vis a higher prevalence of problems affecting the mouth, teeth, and gingiva were found in users who had a lower level of education, used substances daily, had worse self-perception of physical health, did not receive health care and regularly used alcohol and/or tobacco. The results show an association between substance use and decline in oral health, as well as the lack of health services focusing on such issues. Oral health services should be emphasised as a gateway to the health system. So far, the putative cross-referral between services and professionals working in oral health and other health professionals working in the field of drug dependence has not been observed.

Non-medical use of opioid analgesics in contemporary Brazil: Findings from the 2015 Brazilian National Household Survey on Substance Use

Prior studies on substance use in Brazil have not focused on opioid misuse, previously thought to be nearly non-existent. This paper presents new findings on heroin and non-medical use of opioid analgesics. Data come from the 2015 Brazilian Household Survey on Substance Use (BHSU-3), a nationally representative survey estimating epidemiological parameters related to substance use by residents across Brazil. BHSU-3 used stratified multi-stage probability sampling across multiple geographic domains of interest, resulting in 16,273 interviews with household residents. Lifetime heroin use among Brazilians was 0.3 (95% C.I:0.2-0.4). Lifetime, past-year, and past-month non-medical use of opioid analgesics were respectively 2.9 (95%C.I.:2.3-3.4), 1.4 (95%C.I.:1.1-1.7) and 0.6 (95%C.I.:0.4-0.8). Past-year prevalence of non-medical opioid analgesics use was lower among males [Prevalence Ratio (PR): 0.54 (95% C.I.:0.36-0.78)], those aged 12-24 [0.56 (95% C.I.:0.34-0.92)], persons with monthly family incomes between R$1,501-3,000 [0.59 (95% C.I.:0.38-0.92)] or greater than R$3,000 [0.64 (95% C.I.:0.42-0.98)], and persons who were unemployed [0.65 (95% C.I.:0.46-0.92)]. Non-medical use of opioids in Brazil may be more prevalent than previously recognised. Proper measurement and evaluation of opioid misuse across Brazil and other Latin American countries is critical to understand and prevent opioid-related harms.

The impact of urbanization on mental health service provision: a Brazil, Russia, India, China, South Africa and Africa focus

PURPOSE OF REVIEW

Asia and Africa are experiencing rapid urbanization and rural growth. This review focuses on the impact of urbanization on preventive and treatment mental health service provision with attention to the Brazil, Russia, India, China, and South Africa economic bloc and sub-Saharan Africa.

RECENT FINDINGS

A search of the PubMed, Academic Search Ultimate, and Global Health databases, and use of Google Scholar yielded relevant health, environmental, and urban planning research articles from sub-Saharan Africa and Brazil, India, China, and South Africa. Preventive services are ineffective in addressing violence exposure, substance use, poor quality housing, and spatial segregation, with differing trajectories in the various countries. Similarly, the impact of urbanization on social capital and green infrastructure is variable. Although Brazil appears to have a well-developed mental health system, it is unable to meet the care demand. Integrated country-wide and district-based analyses in China indicate planning is underway.

SUMMARY

In general, existing mental and general health services in low and middle-income countries are grossly inadequate in terms of prevention, coverage, and quality to withstand population transitions lying ahead. People with mental disability, as a vulnerable and stigmatized subpopulation, are at high risk of neglect as urbanization progresses, particularly in India and sub-Saharan Africa.

HIV Prevalence, Knowledge, Attitudes, and Practices Among Polydrug Users in Brazil: A Biological Survey Using Respondent Driven Sampling

Brazil has a concentrated HIV epidemic among key populations. In 2009, the Ministry of Health conducted a survey in 10 Brazilian cities aiming to estimate HIV prevalence, knowledge, and associated risk behaviors of polysubstance users (PSU). Using Respondent Driven Sampling (RDS), 3449 PSU were recruited, answered an Audio-Computer Self Assisted Interview (ACASI) and were tested for HIV and syphilis. Analyses were weighted by individual's social network size generated on RDSAT. Pooled HIV prevalence was 5.8% but varied across cities. Most PSU were male, non-white, without income, unemployed, with low levels of education. Overall, 12.0% used injectable drugs, 48.7% had sex with occasional partners and 46.4% engaged in commercial sex. A majority received free condoms (71.4%) but 76.7% exhibited inconsistent condom use. Findings can support policies aiming to improve health care and preventive interventions tailored to this population that remains at high risk of acquiring and transmitting HIV/STI in multiple scenarios.

Rising Trends of Prescription Opioid Sales in Contemporary Brazil, 2009-2015

OBJECTIVES

To present and discuss recent patterns of prescription opioid sales throughout Brazil.

METHODS

We graphed linear trends of opioid prescriptions sold from registered pharmacies across Brazil from 2009 to 2015. We then calculated the change in rate of prescriptions sold per 1000 persons in 2015 compared with 2009.

RESULTS

Opioid sales increased across Brazil from 1 601 043 prescriptions in 2009 to 9 045 945 prescriptions in 2015, corresponding to a 465% increase in 6 years. The largest absolute increase was for codeine products (rate ratio (RR) = 5.30; 95% confidence interval [CI] = 5.29, 5.31), accounting for more than 98% of prescriptions in both years. Oxycodone had the largest relative increase (RR = 11.39; 95% CI = 11.19, 11.59), and fentanyl products had the smallest absolute and relative increase (RR = 2.91; 95% CI = 2.78, 3.03).

CONCLUSIONS

Given rapid increases in opioid sales across Brazil, it is critical to introduce effective prescribing and monitoring methods that allow patients to access necessary medications without escalating risk of opioid misuse and related consequences. Careful surveillance of supply and subsequent outcomes are needed to prevent the development of another devastating opioid epidemic in the Americas.
