Piloting a Savings-Led Microfinance Intervention with Women Engaging in Sex Work in Mongolia: Further Innovation for HIV Risk Reduction

This paper describes a pilot study testing the feasibility of an innovative savings-led microfinance intervention in increasing the economic empowerment and reducing the sexual risk behavior of women engaging in sex work in Mongolia. Women’s economic vulnerability may increase their risk for HIV by compromising their ability to negotiate safer sex with partners and heightening the likelihood they will exchange sex for survival. Microfinance has been considered a potentially powerful structural HIV prevention strategy with women conducting sex work, as diversification of income sources may increase women’s capacity to negotiate safer transactional sex. With 50% of all reported female HIV cases in Mongolia detected among women engaging in sex work, direct prevention intervention with women conducting sex work represents an opportunity to prevent a potentially rapid increase in HIV infection in urban Mongolia. The piloted intervention consisted of a matched savings program in which matched savings could be used for business development or vocational education, combined with financial literacy and business development training for women engaging in sex work. Results of the pilot demonstrate participants’ increased confidence in their ability to manage finances, greater hope for pursuing vocational goals, moderate knowledge gains regarding financial literacy, and an initial transition from sex work to alternative income generation for five out of nine participants. The pilot findings highlight the potential for such an intervention and the need for a clinical trial testing the efficacy of savings-led microfinance programs in reducing HIV risk for women engaging in sex work in Mongolia

“There is no other option; we have to feed our families…who else would do it?”: The Financial Lives of Women Engaging in Sex Work in Ulaanbaatar, Mongolia

Introduction: This article provides an overview of the financial lives of women (n = 204) engaging in sex work in Ulaanbaatar, Mongolia. Methods: This paper presents findings from a computer-based, interviewer-administered baseline assessment administered with women recruited for participation in a randomized controlled trial testing the feasibility of a combined HIV risk reduction and savings-led microfinance intervention for women engaging in sex work in Mongolia. Findings: Findings demonstrate that most women are the primary financial providers for their households, using an array of earning strategies to provide for themselves and other dependents, with sex work often constituting the primary household income source. Financial instability in the lives of people engaging in sex work may increase their risk for HIV and STIs due to a compromised ability to negotiate safer sex with partners in times of economic crisis or need. High levels of financial responsibility for household welfare, when combined with low reported savings, the presence of debt, higher premiums offered for sex without a condom, and high levels of harmful alcohol use, may heighten women’s risk for HIV and other STIs. Conclusion: Further research that documents the financial lives of people working in sex work is needed in order to understand the complex relationship between financial stability and engagement in sex work, and to inform the development and testing of structural HIV prevention interventions which target the economic determinants of risk. These findings highlight the importance of economic support programming for women engaged in sex work in Mongolia at a time of rapid economic change in Mongolia

The impact of a microsavings intervention on reducing violence against women engaged in sex work: a randomized controlled study

Background Women who engage in sex work are at risk for experiencing violence from numerous perpetrators, including paying partners. Empirical evidence has shown mixed results regarding the impact of participation in microfinance interventions on women’s experiences of violence, with some studies demonstrating reductions in intimate partner violence (IPV) and others showing heightened risk for IPV. The current study reports on the impact of participation in a microsavings intervention on experiences of paying partner violence among women engaged in sex work in Mongolia. Methods Between 2011 and 2013, we conducted a two-arm, non-blinded randomized controlled trial (RCT) comparing an HIV/STI risk reduction intervention (HIVSRR) (control condition) to a combined microsavings and HIVSRR intervention (treatment condition). Eligible women (aged 18 or older, reported having engaged in unprotected sex with paying partner in past 90 days, expressed interest in microsavings intervention) were invited to participate. One hundred seven were randomized, including 50 in the control and 57 in the treatment condition. Participants completed assessments at baseline, immediate post-test following HIVSRR, and at 3-months and 6-months after completion of the treatment group intervention. Outcomes for the current study include any violence (physical and/or sexual), sexual violence, and physical violence from paying partners in the past 90 days. Results An intention-to-treat approach was utilized. Linear growth models revealed significant reductions over time in both conditions for any violence (β = −0.867, p < 0.001), physical violence (β = −0.0923, p < 0.001), and sexual violence (β = −1.639, p = 0.001) from paying partners. No significant differences between groups were found for any violence (β = 0.118, p = 0.389), physical violence (β = 0.091, p = 0.792), or sexual violence (β = 0.379, p = 0.114) from paying partners. Conclusions Microsavings participation did not significantly impact women’s risk for paying partner violence. Qualitative research is recommended to understand the cause for reductions in paying partner violence in both study conditions

Natural bovine coronavirus infection in a calf persistently infected with bovine viral diarrhea virus: Viral shedding, immunological features and s gene variations

The evolution of a bovine coronavirus (BCoV) natural infection in a calf persistently infected with bovine viral diarrhea virus (BVDV) was described. The infected calf developed intermittent nasal discharge, diarrhea and hyperthermia. The total number of leukocytes/mL and the absolute differential number of neutrophils and lymphocytes resulted within the normal range, but monocytes increased at T28 (time 28 post‐infection). Flow‐cytometry analysis evidenced that the CD8+ subpopulation increased at T7 and between T28 and T35. BCoV shedding in nasal discharges and feces was detected up to three weeks post infection and high antibody titers persisted up to T56. The RNA BCoV load increased until T14, contrary to what was observed in a previous study where the fecal excretion of BCoV was significantly lower in the co‐infected (BCoV/BVDV) calves than in the calves infected with BCoV only. We can suppose that BVDV may have modulated the BCoV infection exacerbating the long viral excretion, as well as favoring the onset of mutations in the genome of BCoV detected in fecal samples at T21. An extensive study was performed to verify if the selective pressure in the S gene could be a natural mode of variation of BCoV, providing data for the identification of new epidemic strains, genotypes or recombinant betacoronaviruses

Efficacy of a savings-led microfinance intervention to reduce sexual risk for HIV among women engaged in sex work: A randomized clinical trial

Objectives. We tested whether a structural intervention combining savings-led microfinance and HIV prevention components would achieve enhanced reductions in sexual risk among women engaging in street-based sex work in Ulaanbaatar, Mongolia, compared with an HIV prevention intervention alone. Methods. Between November 2011 and August 2012, we randomized 107 eligible women who completed baseline assessments to either a 4-session HIV sexual risk reduction intervention (HIVSRR) alone (n = 50) or a 34-session HIVSRR plus a savings-led microfinance intervention (n = 57). At 3- and 6-month followup assessments, participants reported unprotected acts of vaginal intercourse with paying partners and number of paying partners with whom they engaged in sexual intercourse in the previous 90 days. Using Poisson and zero-inflated Poisson model regressions, we examined the effects of assignment to treatment versus control condition on outcomes. Results. At 6-month follow-up, the HIVSRR plus microfinance participants reported significantly fewer paying sexual partners and were more likely to report zero unprotected vaginal sex acts with paying sexual partners. Conclusions. Findings advance the HIV prevention repertoire for women, demonstrating that risk reduction may be achieved through a structural intervention that relies on asset building, including savings, and alternatives to income from sex work

Cell-free DNA testing in the maternal blood in high-risk pregnancies after first-trimester combined screening

Objective: The objective of this study was to investigate a strategy for clinical implementation of cell-free DNA (cfDNA) testing in high-risk pregnancies after first-trimester combined screening. Methods: In 259 singleton pregnancies undergoing invasive testing after first-trimester combined screening, a maternal blood sample was sent to the laboratory Natera for cfDNA testing using a single-nucleotide polymorphism-based methodology. Results: The cfDNA test provided a result in 249 (96.1%) pregnancies and, among these, identified as being at high risk 35 of 36 cases of trisomy 21, 13 of 13 with trisomy 18, five of five with trisomy 13 and three of four with sex chromosome aneuploidies. A policy of performing an invasive test in women with a combined risk of 651 in 10 or NT 654mm and offering cfDNA testing to the remaining cases would detect all cases of trisomy 21, 18 or 13, 80% of sex aneuploidies and 62.5% of other defects and would avoid an invasive procedure in 82.4% of euploid fetuses. Conclusion: In high-risk pregnancies after combined screening, a policy of selecting a subgroup for invasive testing and another for cfDNA testing would substantially reduce the number of invasive procedures and retain the ability to diagnose most of the observed aneuploidies

Performance of BOADICEA and BRCAPRO genetic models and of empirical criteria based on cancer family history for predicting BRCA mutation carrier probabilities: A retrospective study in a sample of Italian cancer genetics clinics

Abstract Purpose To evaluate in current practice the performance of BOADICEA and BRCAPRO risk models and empirical criteria based on cancer family history for the selection of individuals for BRCA genetic testing. Patients and methods The probability of BRCA mutation according to the three tools was retrospectively estimated in 918 index cases consecutively undergone BRCA testing at 15 Italian cancer genetics clinics between 2006 and 2008. Results 179 of 918 cases (19.5%) carried BRCA mutations. With the strict use of the criteria based on cancer family history 173 BRCA (21.9%) mutations would have been detected in 789 individuals. At the commonly used 10% threshold of BRCA mutation carrier probability, the genetic models showed a similar performance [PPV (38% and 37%), sensitivity (76% and 77%) and specificity (70% and 69%)]. Their strict use would have avoided around 60% of the tests but would have missed approximately 1 every 4 carriers. Conclusion Our data highlight the complexity of BRCA testing referral in routine practice and question the strict use of genetic models for BRCA risk assessment

Measles skin rash: infection of lymphoid and myeloid cells in the dermis precedes viral dissemination to the epidermis

Measles is characterized by fever and a maculopapular skin rash, which is accompanied by immune clearance of measles virus (MV)-infected cells. Histopathological analyses of skin biopsies from humans and non-human primates (NHPs) with measles rash have identified MV-infected keratinocytes and mononuclear cells in the epidermis, around hair follicles and near sebaceous glands. Here, we address the pathogenesis of measles skin rash by combining data from experimentally infected NHPs, ex vivo infection of human skin sheets and in vitro infection of primary human keratinocytes. Analysis of NHP skin samples collected at different time points following MV inoculation demonstrated that infection in the skin precedes onset of rash by several days. MV infection was detected in lymphoid and myeloid cells in the dermis before dissemination to the epidermal leukocytes and keratinocytes. These data were in good concordance with ex vivo MV infections of human skin sheets, in which dermal cells were more targeted than the epidermal cells. To address viral dissemination to the epidermis and to determine whether the dissemination is receptor-dependent, we performed experimental infections of primary keratinocytes collected from healthy donors. These experiments demonstrated that MV infection of keratinocytes is mainly nectin-4- dependent, and differentiated keratinocytes, which express higher levels of nectin-4, are more susceptible to MV infection than proliferating keratinocytes. Based on these data, we propose a model to explain measles skin rash: migrating MV-infected lymphocytes initiate the infection of dermal skin-resident CD150+ immune cells. The infection is subsequently disseminated from the dermal papillae to nectin-4+ keratinocytes in the basal epidermis. Lateral spread of MV infection is observed in the superficial epidermis, most likely due to the higher level of nectin-4 expression on differentiated keratinocytes. Finally, MV-infected cells are cleared by infiltrating immune cells, causing hyperemia and edema, which give the appearance of morbilliform skin rash

Combination Microfinance and HIV Risk Reduction Among Women Engaged in Sex Work

The purpose of this paper is to summarize 15 years of intervention science in combination HIV prevention and microfinance among women engaged in sex work (WESW) in Central Asia, identifying gaps in our understanding and recommendations for future studies. We begin by describing the emergence of HIV/STI risk among WESW in the Central Asia region, specifically Mongolia and Kazakhstan, and bridge to the formative stages of our methodology as well as completed prevention intervention studies. We describe the development of combining HIV prevention with asset-based microfinance interventions, lessons learned, and contributions these studies make to HIV prevention, intervention science, and practice. We end by recommending next steps to move prevention science forward in this area and among this key population, which continues to be underserved in HIV prevention science worldwide
