RESUMO

BACKGROUND: Research on women who inject drugs is scarce in low- and middle-income countries. Women experience unique harms such as sexism and sexual violence which translate into negative health outcomes. The present work aims to provide insight into the experiences of women who inject drugs at the US-Mexico border to identify social and health-related risk factors for overdose to guide harm reduction interventions across the Global South. METHODS: We recruited 25 women ≥ 18 years of age accessing harm reduction and sexual health services at a non-governmental harm reduction organization, "Verter", in Mexicali, Mexico. We employed purposeful sampling to recruit women who inject drugs who met eligibility criteria. We collected quantitative survey data and in-depth interview data. Analyses of both data sources involved the examination of descriptive statistics and thematic analysis, respectively, and were guided by the syndemic and continuum of overdose risk frameworks. RESULTS: Survey data demonstrated reports of initiating injection drug use at a young age, experiencing homelessness, engaging in sex work, being rejected by family members, experiencing physical violence, injecting in public spaces, and experiencing repeated overdose events. Interview data provided evidence of stigma and discrimination toward women, a lack of safe spaces and support systems, risk of overdose-related harms, sexual violence, and the overall need for harm reduction services. CONCLUSION: Women who inject drugs in Mexicali describe experiences of violence, overdose, and public injecting. Women are particularly vulnerable in the Mexicali context, as this area faces a noticeable lack of health and social services. Evidenced-based harm reduction strategies such as safe consumption sites and overdose prevention strategies (e.g., naloxone distribution and training) may benefit this population. Evidence from local organizations could help close the gap in service provision in low-resource settings like Mexico, where government action is almost nonexistent.

RESUMO

OBJECTIVE: To evaluate neuromotor repertoires and developmental milestones in infants exposed to antenatal COVID-19. DESIGN: Longitudinal cohort study. SETTING: Hospital-based study in Los Angeles, USA and Rio de Janeiro, Brazil between March 2020 and December 2021. PARTICIPANTS: Infants born to mothers with COVID-19 during pregnancy and prepandemic control infants from the Graz University Database. INTERVENTIONS: General movement assessment (GMA) videos between 3 and 5 months post-term age were collected and clinical assessments/developmental milestones evaluated at 6-8 months of age. Cases were matched by gestational age, gender and post-term age to prepandemic neurotypical unexposed controls from the database. MAIN OUTCOME MEASURES: Motor Optimality Scores Revised (MOS-R) at 3-5 months. Presence of developmental delay (DD) at 6-8 months. RESULTS: 239 infants were enrolled; 124 cases (83 in the USA/41 in Brazil) and 115 controls. GMA was assessed in 115 cases and 115 controls; 25% were preterm. Median MOS-R in cases was 23 (IQR 21-24, range 9-28) vs 25 (IQR 24-26, range 20-28) in controls, p<0.001. Sixteen infants (14%) had MOS-R scores <20 vs zero controls, p<0.001. At 6-8 months, 13 of 109 case infants (12%) failed to attain developmental milestones; all 115 control infants had normal development. The timing of maternal infection in pregnancy (first, second or third trimester) or COVID-19 disease severity (NIH categories asymptomatic, mild/moderate or severe/critical) was not associated with suboptimal MOS-R or DD. Maternal fever in pregnancy was associated with DD (OR 3.7; 95% CI 1.12 to 12.60) but not suboptimal MOS-R (OR 0.25; 95% CI 0.04 to 0.96). CONCLUSIONS: Compared with prepandemic controls, infants exposed to antenatal COVID-19 more frequently had suboptimal neuromotor development.

RESUMO

BACKGROUND: Fentanyl has led to an increased number of overdose deaths in North America. Testing substances for fentanyl may be a harm reduction strategy to prevent overdose. Little is known about behavior change after fentanyl testing and the attitudes around fentanyl knowledge and testing along the US-Mexico border in the context of a safe consumption site. METHODS: This was a pilot quantitative and qualitative study with 30 women who use drugs at an unsanctioned safe consumption site in Mexicali, Mexico. Women participated in a quantitative survey, a semi-structured interview, and fentanyl testing of substances. Injection behavior was observed after fentanyl testing results were provided. Qualitative data were collected to explore the meanings participants attributed to fentanyl and fentanyl testing. RESULTS: Half of the substances tested positive for fentanyl (n=15, 50%), and all of them were in samples of black tar heroin. Among those participants who tested positive for fentanyl, 7 (47%) subsequently used less of the intended substance, 1 did not use the intended substance, and 7 (47%) did not change their behavior (i.e., used as originally intended). In qualitative interviews, a predominant theme was a description of fentanyl as dangerous and deadly and fentanyl testing as being helpful for modifying drug use behaviors. However, participants recognized that there could be no change in behavior following a positive fentanyl test in the context of not being able to find substances free of fentanyl. CONCLUSION: We observed mixed results related to behavior change after women's intended substance for use tested positive for fentanyl. Fentanyl testing was acceptable to women, but behavior change was hampered by the inability to find substances free of fentanyl. Further research is needed to maximize the potential of fentanyl testing as a harm reduction tool especially in the context of a changing drug supply.

RESUMO

Background: Drug overdoses are prevalent in low- and middle-income countries but are scarcely reported in the literature. We report on an opioid overdose reversal and naloxone distribution program that was instituted at the first safe consumption site in Latin America. Methods: A cross-sectional analysis of witnessed drug overdoses and naloxone distribution between 1 June 2019 and 31 May 2021 in Mexicali, Mexico. Case report forms were entered in an electronic database. Trends in overdose and naloxone distribution were described. Comparisons were made before and after the COVID-19 pandemic was declared in the city. Maps were created to represent the geographic distribution of overdose in the city. Results: During the study period 1,534 doses of naloxone were distributed throughout the community. In addition, there were 464 overdoses reported during this period, of which 4 were fatal. There was a 30% increase in reported overdoses from the period before the COVID-19 pandemic to the period after the pandemic was declared (p = 0.03). Most common substance reported included heroin (93%), sedatives (21%), methamphetamine (16%) and fentanyl (14%). Naloxone was given in 96% of cases (median 1 dose, IQR 1-2 doses) and emergency services were called in 20% of cases. Conclusions: An opioid overdose reversal program in Mexicali, Mexico was able to distribute naloxone and register drug overdoses between 2019 and 2021 as a harm reduction strategy. This adds to the growing body of literature on the impact of community-based programs on preventing fatal overdoses and the potential for implementation in low-resource settings.

RESUMO

OBJECTIVES: HIV-infected women are at increased risk of human papillomavirus (HPV) infection. Time trends in annual prevalences of cervical high-risk human papillomavirus (HR-HPV) genotypes among a non-vaccinated, HIV-infected female cohort in urban Brazil were assessed for the period 2006-2012. METHODS: Cervical specimens were collected for HPV genotyping yearly between January 2006 and December 2012 in a cross-sectional analysis of participants aged ≥18 years enrolled in the Women's HIV Cohort at Fiocruz in Rio de Janeiro, Brazil. Age-adjusted generalized estimating equation models with an exchangeable matrix were used to estimate odds ratios (OR) and 95% confidence intervals (CI) for annual HPV positivity (reference year: 2006). RESULTS: Among the 590 participants, the median age across all study years ranged from 35.5 to 40.0 years. The prevalence of any HR-HPV was ≥53% every year; prevalences of HR-HPV 16, 58, 59, and 68 were ≥24% in at least 1 year. The odds of HPV 16 and 68 decreased in 2012. HPV 58 prevalence followed a U-shape, beginning and ending at >20%. HPV 59 prevalence followed a linear trend, with increased odds in 2012 (OR 16.0, 95% CI 3.8-67.3; Bonferroni-adjusted p-value <0.01). CONCLUSIONS: The prevalences of HR-HPV 58, 59, and 68 were high in this cohort. Given current HR-HPV vaccine coverage and availability, further investigations are needed to optimize vaccine recommendations for this population.

RESUMO

Identifying factors, including human papillomavirus (HPV) genotypes, associated with abnormal anal cytology in HIV-infected women have implications for anal squamous cell cancer (SCC) prevention in HIV-infected women. Anal and cervical samples were collected for cytology, and tested for high-(HR-HPV) and low-risk HPV (LR-HPV) genotypes in a cross-sectional analysis of the IPEC Women's HIV Cohort (Rio de Janeiro, Brazil). Multivariate log-binomial regression models estimated prevalence ratios for factors associated with abnormal anal cytology [≥ atypical squamous cells of undetermined significance, (ASC-US)]. Characteristics of the 863 participants included: median age 42 years, 57% non-white, 79% current CD4+ T-cell count >350 cells/mm(3), 53% HIV-1 viral load <50 copies/mL, median ART duration 5.8 years. Fifty-one percent of anal specimens contained ≥ 1 HR-HPV genotype; 31% had abnormal anal cytology [14% ASC-US, 11% low-grade squamous intra-epithelial lesion, (LSIL); 2% atypical squamous cells-cannot exclude high-grade SIL (ASC-H); 4% high-grade SIL/cancer (HSIL+)]. In multivariate analysis, cervical LSIL+, nadir CD4+ T-cell count ≤ 50 cells/mm(3), HIV-1 viral load ≥ 50 copies/mL, and anal HPV 6, 11, 16, 18, 33, 45, 52, 56, and 58 were associated with ≥ anal ASC-US (p<0.05). Abnormal anal cytology and HR-HPV prevalences were high. HIV-infected women with cervical LSIL+, low nadir CD4+ counts, or detectable HIV-1 viral loads should be a particular focus for enhanced anal SCC screening efforts.

RESUMO

BACKGROUND: Partnership type is an important factor associated with unprotected anal intercourse (UAI) and subsequent risk for HIV and sexually transmitted infections (STI). We examined the association of partnership type with UAI among men who have sex with men (MSM) and male-to-female transgender women (TGW) in Lima, Peru, recently diagnosed with HIV and/or STI. METHODS: We report data from a cross-sectional analysis of MSM and TGW recently diagnosed with HIV and/or STI in Lima, Peru between 2011 and 2012. We surveyed participants regarding UAI with up to their three most recent sexual partners according to partner type. Multivariable Generalized Estimate Equating (GEE) models with Poisson distribution were used to estimate prevalence ratios (PR) for UAI according to partner type. RESULTS: Among 339 MSM and TGW recently diagnosed with HIV and/or STI (mean age: 30.6 years, SD 9.0), 65.5% self-identified as homosexual/gay, 16.0% as bisexual, 15.2% as male-to-female transgender, and 3.3% as heterosexual. Participants provided information on 893 recent male or TGW partners with whom they had engaged in insertive or receptive anal intercourse: 28.9% stable partners, 56.4% non-stable/non-transactional partners (i.e. casual or anonymous), and 14.7% transactional partners (i.e. transactional sex client or sex worker). Unprotected anal intercourse was reported with 41.3% of all partners. In multivariable analysis, factors associated with UAI included partnership type (non-stable/non-transactional partner APR 0.73, [95% CI 0.59-0.91], transactional partner APR 0.53 [0.36-0.78], p<0.05) and the number of previous sexual encounters with the partner (>10 encounters APR 1.43 [1.06-1.92], p<0.05). CONCLUSION: UAI was more commonly reported for stable partners and in partnerships with >10 sexual encounters, suggesting UAI is more prevalent in partnerships with a greater degree of interpersonal commitment. Further research assessing partner-level factors and behavior is critical for improving HIV and/or STI prevention efforts among Peruvian MSM and TGW.
