Background: Women employed by sex work (WESW) have a high risk of human immunodeficiency virus (HIV) infection and experience economic barriers in accessing care. However, few studies have described their financial lives and the relationship between expenditures and HIV-related behaviors. Methods: This exploratory study used financial diaries to collect expenditure and income data from WESW in Uganda over 6 months. Data were collected as part of a larger trial that tested the efficacy of an HIV prevention intervention method. Descriptive statistics were used to quantify women’s income, relative expenditures, and negative cash balances. Bivariate and multivariate logistic regressions were used to examine the odds of sexual risk behavior or use of HIV medications for several cash scenarios. Results: A total of 163 WESW were enrolled; the participants mean age was 32 years old. Sex work was the sole source of employment for most WESW (99%); their average monthly income was $62.32. Food accounted for the highest proportion of spending (44%) followed by sex work (20%) and housing expenditures (11%). WESW spent the least on health care (5%). Expenditures accounted for a large but variable proportion of these women’s income (56% to 101%). Most WESW (74%) experienced a negative cash balance. Some also reported high sex work (28%), health care (24%), and education (28%) costs. The prevalence of condomless sex (77%) and sex with drugs/alcohol (70%) was high compared to use of ART/PrEP (Antiretroviral therapy/Pre-exposure prophylaxis) medications (45%). Women’s cash expenditures were not statistically significantly associated with HIV-related behaviors. However, the exploratory study observed a consistent null trend of lower odds of condomless sex (adjusted odds ratio (AOR) = 0.70, 95% confidence interval (CI): 0.28–1.70), sex with drugs/alcohol (AOR = 0.93, 95% CI: 0.42–2.05), and use of ART/PrEP (AOR = 0.80, 95% CI: 0.39–1.67) among women who experienced a negative cash balance versus those who did not. Similar trends were observed for other cash scenarios. Conclusion: Financial diaries are a feasible tool to assess the economic lives of vulnerable women. Despite having paid work, most WESW encountered a myriad of financial challenges with limited spending on HIV prevention. Financial protections and additional income-generating activities may improve their status. More robust research is needed to understand the potentially complex relationship between income, expenditures, and HIV risk among vulnerable sex workers.

Objectives. To explore whether beneficial health care policies, when implemented in the context of gender inequality, yield unintended structural consequences that stigmatize and ostracize women with HIV from “what matters most” in local culture. Methods. We conducted 46 in-depth interviews and 5 focus groups (38 individuals) with men and women living with and without HIV in Gaborone, Botswana, in 2017. Results. Cultural imperatives to bear children bring pregnant women into contact with free antenatal services including routine HIV testing, where their HIV status is discovered before their male partners’. National HIV policies have therefore unintentionally reinforced disadvantage among women with HIV, whereby men delay or avoid testing by using their partner’s status as a proxy for their own, thus facilitating blame toward women diagnosed with HIV. Gossip then defines these women as “promiscuous” and as violating the essence of womanhood. We identified cultural and structural ways to resist stigma for these women. Conclusions. Necessary HIV testing during antenatal care has inadvertently perpetuated a structural vulnerability that propagates stigma toward women. Individual- and structural-level interventions can address stigma unintentionally reinforced by health care policies.

Women who exchange sex and use drugs (WESUD) are at high risk for HIV infection and partner violence. The few tested interventions at the intersection of HIV and IPV show mixed results. This analysis examined the impact of a combination HIV risk reduction (HIVRR) and microfinance (MF) intervention on reported paying and intimate partner violence against WESUD in Kazakhstan. This cluster randomized controlled trial enrolled 354 women from 2015 to 2018 and randomized them to either a combination of HIVRR and MF intervention or HIVRR alone. Outcomes were assessed at four time points over 15 months. Logistic regression within a Bayesian approach assessed change in odds ratio (OR) of recent physical, psychological, or sexual violence perpetrated by current or past intimate partners; and paying partners/clients by study arm over time. Compared to the control arm, the combination intervention decreased the odds of participants experiencing physical violence from past intimate partners by 14% (OR = 0.861, p = 0.049). Women in the intervention group reported significantly lower rates of sexual violence from paying partners (HIVRR + MF - HIVRR: 25.9%; OR = 0.741, p = 0.019) at 12-month follow-up. No significant differences in rates from current intimate partners were found. A combination HIVRR and microfinance intervention may reduce gender-based violence from paying and intimate partners among WESUD above and beyond HIVRR interventions alone. Future research should examine how microfinance reduces partner violence and how to implement combination interventions in diverse settings.

Women engaged in sex work (WESW) in Uganda face a high risk of HIV and other sexually transmitted infections (STIs), driven by the intersection of gender inequality, poverty and structural barriers. This paper reports on the Kyaterekera Project, a cluster-randomized controlled trial (c-RCT) testing the efficacy of a combined HIV risk reduction (HIVRR) and economic empowerment intervention to reduce biologically confirmed STIs and HIV risk behaviours. The study recruited 542 WESW from 19 HIV hotspots across four districts in Uganda between June 2019 and March 2020. Participants were randomized into three groups: (1) HIVRR intervention alone; (2) HIVRR combined with financial literacy training and an unconditional matched savings account; or (3) HIVRR combined with financial literacy training and an unconditional matched savings account and vocational training. Although initially implemented as a three-arm c-RCT, the COVID-19 lockdown prevented the implementation of the vocational training component. Therefore, the two treatment groups were combined, and the trial was re-approved as a two-arm c-RCT. Biological assessments were conducted at baseline, 18 and 24 months. Behavioural assessments were conducted at baseline, 6, 12, 18 and 24 months from April 2019 to December 2023. Primary outcomes included incident HIV acquisitions (seroconversions among baseline HIV-negative participants), point prevalence of STIs at each visit, and the number/proportion of unprotected sexual acts with paying and regular partners. This study utilized community-based participatory research methods, engaging a community advisory board to ensure the study's alignment with local needs. Across follow-up, condomless sex with paying partners decreased and income shifted towards non-sex work in both arms; no between-group differences were detected. Eighteen incident HIV acquisitions occurred (14 by 18 months; 4 additional by 24 months) with no between-group differences. STI prevalence was lower at 18 months compared to baseline, but not sustained at 24 months. In an environment of high baseline HIV prevalence, substantial pre-exposure prophylaxis uptake and COVID-19 disruptions, the added financial literacy/savings components did not yield measurable incremental benefits over HIVRR alone. Integrating an unconditional matched-savings model within an HIVRR platform was feasible. NCT03583541.

Seasonal windows of opportunity are intervals within a year that provide improved prospects for growth, survival, or reproduction. However, few studies have sufficient temporal resolution to examine how multiple factors combine to constrain the seasonal timing and extent of developmental opportunities. Here, we document seasonal changes in milkweed (Asclepias fascicularis)–monarch (Danaus plexippus) interactions with high resolution throughout the last three breeding seasons prior to a precipitous single‐year decline in the western monarch population. Our results show early‐ and late‐season windows of opportunity for monarch recruitment that were constrained by different combinations of factors. Early‐season windows of opportunity were characterized by high egg densities and low survival on a select subset of host plants, consistent with the hypothesis that early‐spring migrant female monarchs select earlier‐emerging plants to balance a seasonal trade‐off between increasing host plant quantity and decreasing host plant quality. Late‐season windows of opportunity were coincident with the initiation of host plant senescence, and caterpillar success was negatively correlated with heatwave exposure, consistent with the hypothesis that late‐season windows were constrained by plant defense traits and thermal stress. Throughout this study, climatic and microclimatic variations played a foundational role in the timing and success of monarch developmental windows by affecting bottom‐up, top‐down, and abiotic limitations. More exposed microclimates were associated with higher developmental success during cooler conditions, and more shaded microclimates were associated with higher developmental success during warmer conditions, suggesting that habitat heterogeneity could buffer the effects of climatic variation. Together, these findings show an important dimension of seasonal change in milkweed–monarch interactions and illustrate how different biotic and abiotic factors can limit the developmental success of monarchs across the breeding season. These results also suggest the potential for seasonal sequences of favorable or unfavorable conditions across the breeding range to strongly affect monarch population dynamics. Few studies have observed species interactions with sufficient temporal resolution to examine how multiple factors combine to constrain the seasonal timing and extent of developmental opportunities. Our results show early‐ and late‐season windows of opportunity for monarch recruitment and indicate that these windows were constrained by different combinations of factors. These findings show an important dimension of seasonal change in milkweed‐monarch interactions and suggest the potential for seasonal sequences of favorable or unfavorable conditions across the breeding range to strongly affect monarch population dynamics.

Background The global HIV burden remains a public health concern. Women engaged in sex work (WESW) are at higher risk of acquiring HIV compared to the general adult population. Uganda reports high rates of HIV prevalence among WESW. While WESW in Uganda have long been the subject of surveillance studies, they have not been targeted by theory-informed HIV prevention intervention approaches. In this study, we explored the perceived benefits of an evidence-based HIV risk reduction intervention that was implemented as part of a combination intervention tested in a clinical trial in Uganda. Methods As part of a larger randomized clinical trial, we conducted semi-structured in-depth interviews with 20 WESW selected using a stratified purposive sampling. All interviews were conducted in Luganda, language spoken in the study area, and audio-recorded. They were transcribed verbatim and translated to English. Thematic analysis was used to analyze the data. Results WESW’s narratives focused on: (1) condom use; (2) alcohol/drug consumption; (3) PrEP use; (4) “handling” customers; and (5) \"massaging” customers. WESW agreed that male condom was one of the important learning points for them and planned to continue using them while female condoms were received with mixed reactions. Many women appreciated receiving information about the risks of consuming alcohol and drugs, and discussed how they reduced/ eliminated their consumption. PrEP information was appreciated though identified by fewer WESW. Handling a client was discussed as a helpful strategy for safer sex through improved ability to convince customers to use condoms or avoiding sex. Massaging was also beneficial to avoid penetrative sex, but similar to female condom, massaging also yielded mixed perceptions. Conclusion WESW found the intervention beneficial and described ways in which it improved their ability to engage in safer sex and stay healthy. The fact that WESW identified other strategies beyond condom use as helpful underlines the importance of adopting a comprehensive approach to behavioral interventions targeting HIV prevention even when combined with other interventions. Additionally, WESW’s narratives suggest that incorporating the tenets of social cognitive theory and harm reduction approaches in HIV prevention among this population can result in risk behavior change.

We examined the factors associated with consistent condom use among women engaged in sex work in the Southern parts of Uganda. We used baseline data from a longitudinal study involving WESW from 19 hotspots in Southern Uganda. We conducted hierarchical models to determine the individual, economic, behavioral, and health-related factors associated with consistent condom use. We found that, alcohol use (b=-0.48, 95% CI=-0.77, -0.19), accepting money for condomless sex (b=-0.33, 95% CI=-0.38, -0.28), multiple customers (b=-0.01, 95% CI=-0.01, -0.005), being married (b = 0.50, 95% CI = 0.01, 0.99), owning more assets (b = 0.08, 95% CI = 0.05, 0.13), having another income earner in the household (b = 0.55, 95% CI = 0.27, 0.83), condom use self-efficacy (b = 0.11, 95% CI = 0.03, 0.19), condom use communication (b = 0.06, 95% CI = 0.001, 0.12), and being knowledgeable about HIV/STIs transmission (b = 0.08, 95% CI = 0.01, 0.15) were associated with consistent condom use. Additionally, 29% of the women were consistent condom users. Hence, there is need to implement interventions that promote consistent condom use among WESW.

The disruption of conventional manufacturing, supply, and distribution channels during the COVID-19 pandemic caused widespread shortages in personal protective equipment (PPE) and other medical supplies. These shortages catalyzed local efforts to use nontraditional, rapid manufacturing to meet urgent healthcare needs. Here we present a crisis-responsive design framework designed to assist with product development under pandemic conditions. The framework emphasizes stakeholder engagement, comprehensive but efficient needs assessment, rapid manufacturing, and modified product testing to enable accelerated development of healthcare products. We contrast this framework with traditional medical device manufacturing that proceeds at a more deliberate pace, discuss strengths and weakness of pandemic-responsive fabrication, and consider relevant regulatory policies. We highlight the use of the crisis-responsive framework in a case study of face shield design and production for a large US academic hospital. Finally, we make recommendations aimed at improving future resilience to pandemics and healthcare emergencies. These include continued development of open source designs suitable for rapid manufacturing, education of maker communities and hospital administrators about rapidly-manufactured medical devices, and changes in regulatory policy that help strike a balance between quality and innovation.

The rapid spread of COVID-19 and disruption of normal supply chains has resulted in severe shortages of personal protective equipment (PPE), particularly devices with few suppliers such as powered air-purifying respirators (PAPRs). A scarcity of information describing design and performance criteria for PAPRs represents a substantial barrier to mitigating shortages. We sought to apply open-source product development (OSPD) to PAPRs to enable alternative sources of supply and further innovation. We describe the design, prototyping, validation, and user testing of locally manufactured, modular, PAPR components, including filter cartridges and blower units, developed by the Greater Boston Pandemic Fabrication Team (PanFab). Two designs, one with a fully custom-made filter and blower unit housing, and the other with commercially available variants (the “Custom” and “Commercial” designs, respectively) were developed; the components in the Custom design are interchangeable with those in Commercial design, although the form factor differs. The engineering performance of the prototypes was measured and safety validated using National Institutes for Occupational Safety and Health (NIOSH)-equivalent tests on apparatus available under pandemic conditions at university laboratories. Feedback was obtained from four individuals; two clinicians working in ambulatory clinical care and two research technical staff for whom PAPR use is standard occupational PPE; these individuals were asked to compare PanFab prototypes to commercial PAPRs from the perspective of usability and suggest areas for improvement. Respondents rated the PanFab Custom PAPR a 4 to 5 on a 5 Likert-scale 1) as compared to current PPE options, 2) for the sense of security with use in a clinical setting, and 3) for comfort compared to standard, commercially available PAPRs. The three other versions of the designs (with a Commercial blower unit, filter, or both) performed favorably, with survey responses consisting of scores ranging from 3 to 5. Engineering testing and clinical feedback demonstrate that the PanFab designs represent favorable alternatives to traditional PAPRs in terms of user comfort, mobility, and sense of security. A nonrestrictive license promotes innovation in respiratory protection for current and future medical emergencies.

Abstract Proper disinfection using adequate disinfecting agents will be necessary for infection control strategies against coronavirus disease 2019 (COVID-19). However, limited guidance exists on effective surface disinfectants or best practices for their use against severe acute respiratory coronavirus 2. We outlined a process of fully characterizing over 350 products on the Environmental Protection Agency List N, including pH, method of delivery, indication for equipment sterilization, and purchase availability. We then developed a streamlined set of guidelines to help rapidly evaluate and select suitable disinfectants from List N, including practicality, efficacy, safety, and cost/availability. This resource guides the evaluation of ideal disinfectants amidst practical considerations posed by the COVID-19 pandemic.
