RESUMO

INTRODUCTION: Adherence counselling with point-of-care (POC) drug-level feedback using a novel tenofovir assay may support pre-exposure prophylaxis (PrEP) adherence; however, perceptions of urine testing and its impact on adherence are not well studied. We qualitatively examined how POC tenofovir testing was experienced by transgender women (TGW) in Uganda. METHODS: Within a cluster randomized trial of peer-delivered HIV self-testing, self-sampling for sexually transmitted infections and PrEP among HIV-negative TGW showing overall low PrEP prevention-effective adherence (NCT04328025), we conducted a nested qualitative sub-study of the urine POC assay among a random sample of 30 TGW (August 2021-February 2022). TGW interviews explored: (1) experiences with POC urine tenofovir testing and (2) perceptions of PrEP adherence counselling with drug-level feedback. We used an inductive content analytic approach for analysis. RESULTS: Median age was 21 years (interquartile range 20-24), and 70% engaged in sex work. Four content categories describe how TGW experienced POC urine tenofovir testing: (1) Urine tenofovir testing was initially met with scepticism: Testing urine to detect PrEP initially induced anxiety, with some perceptions of being intrusive and unwarranted. With counselling, however, participants found POC testing acceptable and beneficial. (2) Alignment of urine test results and adherence behaviours: Drug-level feedback aligned with what TGW knew about their adherence. Concurrence between pill taking and tenofovir detection in urine reinforced confidence in test accuracy. (3) Interpretation of urine tenofovir results: TGW familiar with the interpretation of oral-fluid HIV self-tests knew that two lines on the test device signified positivity (presence of HIV). However, two lines on the urine test strip indicated a positive result for non-adherence (absence of tenofovir), causing confusion. Research nurses explained the difference in test interpretation to participants' satisfaction. (4) White coat dosing: Some TGW deliberately chose not to attend scheduled clinic appointments to avoid detecting their PrEP non-adherence during urine testing. They restarted PrEP before returning to clinic, a behaviour called "white coat dosing." CONCLUSIONS: Incorporating POC urine testing into routine PrEP adherence counselling was acceptable and potentially beneficial for TGW but required attention to context. Additional research is needed to identify effective strategies for optimizing adherence monitoring and counselling for this population.

RESUMO

We conducted qualitative research among people with HIV (PWH) and care providers in Cape Town, South Africa to understand the impact of negative clinic experiences on adherence and support preferences. In-depth interviews were conducted with 41 patients with an unsuppressed viral load or a treatment gap, and focus group discussions with physicians, nurses, counselors, and community health workers. Questions addressed treatment history and adherence barriers, then participants evaluated evidence-based adherence interventions for potential scale up. Inductive analysis examined care experiences and corresponding preference for intervention options. More than half of PWH described negative experiences during clinic visits, including mistreatment by staff and clinic administration issues, and these statements were corroborated by providers. Those with negative experiences in care stated that fear of mistreatment led to nonadherence. Most patients with negative experiences preferred peer support groups or check-in texts to clinic-based interventions. We found that PWH's negative clinic experiences were a primary reason behind nonadherence and influenced preferences for support mechanisms. These findings emphasize the importance of HIV treatment adherence interventions at multiple levels both in and outside of the clinic, and providing more comprehensive training to providers to better serve PWH in adherence counseling, especially those who are most vulnerable..

RESUMO

Real-time electronic adherence monitoring involves "smart" pill boxes that record and monitor openings as a proxy for pill taking and may be useful in understanding and supporting PrEP use; however, acceptability and/or feasibility for PrEP users is uncertain. We sought to understand the experiences of using a real-time electronic adherence monitor for PrEP delivery among young women in Kisumu and Thika, Kenya. We used the Wisepill device to monitor PrEP use among 18-24-year-old women for two years. Half of the participants were randomized to also receive SMS adherence reminders (daily or as needed for missed doses). We assessed acceptability quantitatively and qualitatively according to the four constructs of Unified Theory of Acceptance and Use of Technology (UTAUT): performance expectancy, effort expectancy, social influence, and facilitating conditions. We assessed feasibility by monitor functionality during periods of PrEP use. We analyzed quantitative data descriptively and compared by site and over time; qualitative data were analyzed inductively and deductively. The median age was 21 years (IQR 19-22), median education was 12 years (IQR 10-13), 182 (53%) had disclosed PrEP use, and 55 (16%) reported recent intimate partner violence. Most participants reported high levels of usefulness and high interest in using the monitor with few problems or worries reported throughout follow-up. Feasibility was high overall with some differences by site (96% functional monitor days in Kisumu vs 88% in Thika). Few monitors were reported lost (N = 29; 8%) or dysfunctional (N = 11; 3%). In qualitative interviews, electronic monitoring was perceived as useful because it supported privacy, confidentiality, easy storage, and PrEP adherence. Effort was generally considered low. Participants expressed some concern for stigma from monitor and/or PrEP use. Facilitating conditions involved the monitor size, color, and battery life. Overall, real-time electronic adherence monitoring was a highly acceptable and feasible approach to understand PrEP adherence among young women in a sub-Saharan African setting.

RESUMO

INTRODUCTION: Young women in sub-Saharan Africa are a priority population for HIV prevention, yet challenges with adherence and persistence to HIV pre-exposure prophylaxis (PrEP) are common. This study involved the development and pilot testing of My Way-a novel delivery system for PrEP and co-packaged sexual health services. METHODS: My Way was developed in Kisumu, Kenya through a user-centred design process (2020). The intervention involves peer-delivery and support for HIV testing and PrEP use, self-collected vaginal swabs for sexually transmitted infection (STI) testing, pregnancy testing, oral contraceptive pills, self-injectable medroxyprogesterone and/or condoms. My Way was assessed among 16- to 24-year-old sexually active women in a randomized controlled trial versus standard of care (SoC; 2021-2022). Use of PrEP and other sexual health services were tracked at 1, 3 and 6 months for feasibility. Acceptability was determined by questionnaire. The effect of the intervention on tenofovir diphosphate (TFV-DP) levels was assessed by chi-square test (primary outcome); other predictors were explored with regression analysis. RESULTS: Among 150 women, the median age was 22 years and the median number of sexual partners was 2. Moderate/severe depression was common (60%). In the intervention arm, peers made 88% (198/225) of possible kit deliveries (177 with PrEP) and 49 STIs were diagnosed. In the SoC arm, 24% (55/225) of expected clinic visits occurred (53 with PrEP); no STI testing was performed. TVF-DP was detected in 16 participants at 6 months: 16% (12/75) in the intervention arm versus 5% (4/75) in the SoC arm (p = 0.03). Persistence among those with ongoing HIV prevention needs (i.e. prevention-effective persistence) was 18% (12/67) versus 7% (4/56; p = 0.08). No women acquired HIV. The intervention was significantly associated with detectable TFV-DP (OR 3.5, 1.1-11.4; p = 0.04); moderate/severe depression trended towards an association with TFV-DP (OR 0.2, 0.03-1.6; p = 0.13). CONCLUSIONS: My Way is a promising delivery system for PrEP and other sexual health services among young women in Western Kenya. We found high feasibility and acceptability. PrEP use was modest, but higher with My Way compared to SoC. Long-acting PrEP formulations may overcome important barriers to PrEP use and should be explored in combination with the My Way delivery model.

RESUMO

BACKGROUND: A total of 700 000 US children and adolescents are estimated to have latent tuberculosis (TB) infection. Identifying facilitators and barriers to engaging in TB infection care is critical to preventing pediatric TB disease. We explored families' and clinicians' perspectives on pediatric TB infection diagnosis and care. METHODS: We conducted individual interviews and small group discussions with primary care and subspecialty clinicians, and individual interviews with caregivers of children diagnosed with TB infection. We sought to elicit facilitators and barriers to TB infection care engagement. We used applied thematic analysis to elucidate themes relating to care engagement, and organized themes using a cascade-grounded pediatric TB infection care engagement framework. RESULTS: We enrolled 19 caregivers and 24 clinicians. Key themes pertaining to facilitators and barriers to care emerged that variably affected engagement at different steps of care. Clinic and health system themes included the application of risk identification strategies and communication of risk; care ecosystem accessibility; programs to reduce cost-related barriers; and medication adherence support. Patient- and family-level themes included TB knowledge and beliefs; trust in clinicians, tests, and medical institutions; behavioral skills; child development and parenting; and family resources. CONCLUSIONS: Risk identification, education techniques, trust, family resources, TB stigma, and care ecosystem accessibility enabled or impeded care cascade engagement. Our results delineate an integrated pediatric TB infection care engagement framework that can inform multilevel interventions to improve retention in the pediatric TB infection care cascade.

RESUMO

Globally, over one million people acquire curable sexually transmitted infections (STI) each day. Understanding how people think about STIs is key to building culturally appropriate STI prevention and treatment programs. We explored STI knowledge and perceptions in rural, southwestern Uganda to inform future interventions. From August 2020 to December 2020, we conducted individual in-depth interviews among adult men and women (≥18 years) with recent or current personal or partner pregnancy, a history of an STI diagnosis and treatment, and membership in an HIV-sero-different relationship. Interviews explored STI knowledge, perceptions, and barriers and facilitators to engaging in STI care. We used inductive and deductive approaches to generate a codebook guided by the healthcare literacy skills framework in a thematic analysis. Ten men with STI, five of their female partners, eighteen women with STI, and four of their male partners participated in individual in-depth interviews. The median age was 41 (range 27-50) for men and 29 (range 22-40) for women. Sixteen (43%) participants were with HIV. Significant themes include: 1) Participants obtained STI knowledge and information from the community (friends, family members, acquaintances) and medical professionals; 2) While participants knew STIs were transmitted sexually, they also believed transmission occurred via non-sexual mechanisms. 3) Participants associated different connotations and amounts of stigma with each STI, for example, participants reported that syphilis was passed down "genetically" from parent to child. 4) Participants reported uncertainty about whether STIs affected pregnancy outcomes and whether antenatal STI treatment was safe. The complicated nature of STIs has led to understandable confusion in settings without formal sexual healthcare education. Robust counseling and education prior to sexual debut will help allow men and women to understand the signs, symptoms, and treatments necessary for STI cure and to navigate often complicated and overburdened healthcare systems.

RESUMO

Timely initiation of and adherence to antiretroviral therapy (ART) is critical for improving HIV outcomes and reducing HIV transmissibility. Social networks, or the social relationships individuals have with each other, have been linked with positive health outcomes, but less is known about the extent to which social network composition and structure are associated with improved ART adherence among people living with HIV (PLWH). We conducted an ego-centric network study among 828 previously ART-naïve PLWH presenting for ART initiation at 11 clinics in Mbarara, Uganda (rural population) and Gugulethu, South Africa (peri-urban population). We collected social network data using name generator and name interpreter questions. ART adherence was monitored over 12 months using wireless monitors (Wisepill). Our primary outcome of interest was ART adherence during the 12-month follow-up period. We used generalized linear models to estimate the associations between network measures and ART adherence. PLWH at the Uganda site (compared with the South Africa site) were less isolated, had larger social networks, and had more social ties providing sufficient social support; they were also more likely to bridge different social groups whereby not all social ties were connected to each other. In Uganda, social isolation was associated with a 5.5 percentage point reduction in ART adherence (95% confidence interval [CI] -9.95 to -1.13; p = 0.014), while having more same gender social ties was associated with higher ART adherence (b = 0.13, 95% CI 0.02-0.25, p = 0.025). In South Africa, there was no association between social isolation and ART adherence, and having more friendship ties (vs. family ties) was associated with lower ART adherence (b = -2.20, 95% CI -3.56 to -0.84; p = 0.002). Identifying and supporting PLWH who are isolated may facilitate optimal adherence, but understanding how networks differentially affect ART adherence by country context is important.

RESUMO

Alcohol use and HIV infection are prevalent in sub-Saharan Africa (sSA), and both are associated with low birth weight. Yet, few studies have evaluated the combined effects of maternal HIV infection and alcohol use on birth outcomes. We analyzed data from a prospective cohort study of HIV-related placental changes in Ugandan women. We defined alcohol use as self-reported alcohol use within the last year, using the AUDIT questionnaire and used linear and logistic regression to measure associations between maternal alcohol use, HIV serostatus, and birth weight. In a subsample, we measured alcohol exposure using phosphatidylethanol (PEth) in neonatal heelstick dried blood spots to confirm maternal alcohol use. Of 352 participants, 176 (50%) were women with HIV (WHIV). Three of 176 (2%) HIVuninfected women and 17/176 (10%) of WHIV self-reported alcohol use (P = 0.002). Maternal HIV infection was associated with lower birth weight (ß = -0.12, 95% CI [-0.20, -0.02], P = 0.02), but self-reported alcohol use was not (ß = 0.06, 95% CI [-0.15, 0.26], P = 0.54), and the interaction between HIV serostatus and alcohol use was not significant (P = 0.13). Among the PEth subsample, neither HIV status nor PEthconfirmed alcohol use were associated with low birth weight. Maternal HIV infection was associated with lower birth weight, but alcohol use was not, and there was no significant interaction between maternal HIV infection and alcohol use. Alcohol use was more prevalent in WHIV and under-reporting was common. A larger study of the effects of laboratory-confirmed alcohol and HIV exposure on birth outcomes is warranted.

RESUMO

Non-communicable diseases (NCDs) are a growing health burden in Sub-Saharan Africa and especially Uganda, where they account for over one third of all deaths. During the COVID-19 pandemic, public health control measures such as societal "lockdowns" had a significant impact on longitudinal NCD care though no studies have looked at the lived experience around NCD care during the pandemic. Our objective was to understand the experience of NCD care for both patients and providers in southwestern Uganda during the COVID-19 pandemic. We conducted in-depth, in-person qualitative interviews with 20 patients living with hypertension, diabetes, and/or cardiac disease purposefully selected from the outpatient clinics at Mbarara Regional Referral Hospital and 11 healthcare providers from public health facilities in Mbarara, southwestern Uganda. We analyzed transcripts according to conventional content analysis. We identified four major themes that emerged from the interviews; (1) difficulty accessing medication; (2) food insecurity; (3) barriers to the delivery of NCD clinical care and (4) alternative forms of care. Pre-existing challenges with NCD care were exacerbated during COVID-19 lockdown periods and care was severely disrupted, leading to worsened patient health and even death. The barriers to care were exacerbations of underlying systemic problems with NCD care delivery that require targeted interventions. Future work should leverage digital health interventions, de-centralizing NCD care, improving follow-up, providing social supports to NCD patients, and rectifying supply chain issues.

RESUMO

We conducted a pilot randomized controlled trial among patients initiating treatment for drug-sensitive tuberculosis (TB). Participants received real-time electronic adherence monitors and were randomized (1:1:1) to: (i) daily SMS (reminders to TB patients and notifications to social supporters sent daily for 3 months, then triggered by late or missed dosing for 3 months); (ii) weekly SMS (reminders to TB patients and notifications to social supporters sent weekly for 3 months, then triggered by late or missed dosing for 3 months); or (iii) control (no SMS). Feasibility was mainly verified by the technical function of the intervention at Month 6. The primary outcome was percent adherence as ascertained by the real time monitor. Quantitative feasibility/acceptability data were summarized descriptively. Percentage adherence and adherence patterns were assessed and compared by linear regression models. Qualitative acceptability data was collected through interviews and analyzed using content analysis. Among 63 participants, the median age was 35 years, 75% had no regular income, and 84% were living with HIV. Feasibility was demonstrated as most of the daily [1913/2395 (80%)] and weekly [631/872 (72%)] SMS reminders to TB patients were sent successfully. Also, most of the daily [1577/2395 (66%)] and weekly [740/872 (85%)] SMS notifications to social supporters and adherence data (96%) were sent successfully. Challenges included TB status disclosure, and financial constraints. All patients perceived the intervention to be useful in reminding and motivating them to take medication. Median adherence (IQR) in the daily SMS, weekly SMS, and control arms was 96.1% (84.8, 98.0), 92.5% (80.6, 96.3), and 92.2% (56.3, 97.8), respectively; however, differences between the intervention and control arms were not statistically significant. Real-time monitoring linked to SMS was feasible and acceptable and may have improved TB medication adherence. Larger studies are needed to further assess impact on adherence and clinical outcomes.

RESUMO

INTRODUCTION: Peer delivery is a client-centred approach that could maximize the coverage and impact of HIV services for transgender women (TGW). We conducted qualitative interviews to examine how peer-delivered HIV self-testing (HIVST), sexually transmitted infection self-sampling (STISS) and oral pre-exposure prophylaxis (PrEP) influenced prevention choices among TGW and their intimate partners in Uganda. METHODS: Within a cluster randomized trial of peer-delivered HIVST, STISS and PrEP among HIV-negative TGW (NCT04328025), we conducted 55 qualitative interviews with 30 TGW, 15 intimate partners and 10 TGW peers (August 2021-February 2022). TGW interviews explored: (1) HIV self-test and PrEP experiences; (2) HIVST with intimate partners; and (3) descriptions of self-sampling for STI testing. Partner interviews covered: (1) experiences with HIVST; (2) disclosure of HIV status to intimate partner; and (3) descriptions of sexual behaviours after testing. Peer interview topics included: (1) intervention delivery experiences; and (2) recommendations for peer-delivered HIV prevention services to TGW, including psychological support and coping strategies. Qualitative data were analysed using an inductive content analytic approach. RESULTS: Peer-delivered combination prevention was valued by this group of TGW and their partners. (1) Peer services extended beyond delivering HIV/STI kits and PrEP refills to caring for individual health and wellbeing by providing stigma coping strategies. Peer psychosocial support empowered research participants to become "HIVST ambassadors," teach non-study TGW about self-testing and PrEP, and encourage linkage to care. (2) HIVST with intimate partners and mutual disclosure of HIV status strengthened partnered relationships. PrEP use after both partners tested HIV negative implied infidelity. (3) Self-sampling enabled TGW to take control of their STI testing and avoid the embarrassment of exposing their bodies. Privacy and confidentiality motivated the uptake of STI testing and treatment. CONCLUSIONS: In this sample of TGW from Uganda, peer delivery of HIVST, STISS and PrEP refills benefitted individual prevention efforts and extended to a new linkage of TGW not engaged in care. Integrating peer services into differentiated PrEP delivery could increase HIV/STI test coverage and PrEP use in this vulnerable population.

RESUMO

Most human immunodeficiency virus (HIV) infections occur in cisgender women in resource-limited settings. In women, self-protection with emtricitabine/tenofovir disoproxil fumarate pre-exposure prophylaxis (FTC/TDF-PrEP) constitutes a major pillar of HIV prevention. However, clinical trials in women had inconsistent outcomes, sparking uncertainty about adherence requirements and reluctance in evaluating on-demand regimens. We analyzed data from published FTC/TDF-PrEP trials to establish efficacy ranges in cisgender women. In a 'bottom-up' approach, we modeled hypotheses in the context of risk-group-specific, adherence-efficacy profiles and challenged those hypotheses with clinical data. We found that different clinical outcomes were related to the proportion of women taking the product, allowing coherent interpretation of the data. Our analysis showed that 90% protection was achieved when women took some product. We found that hypotheses of putative male/female differences were either not impactful or statistically inconsistent with clinical data. We propose that differing clinical outcomes could arise from pill-taking behavior rather than biological factors driving specific adherence requirements in cisgender women.

RESUMO

Background: Daily, oral tenofovir disoproxil fumarate/emtricitabine (TDF/FTC) as pre-exposure prophylaxis (PrEP) reduces HIV acquisition for African women. Adherence is key to efficacy and patterns of adherence can be highly variable in real-world settings. Using group-based trajectory modeling (GBTM), we sought to identify distinct patterns of periconception PrEP adherence and evaluate potential baseline predictors of such adherence trajectories. Methods: We conducted a single-arm longitudinal study for women aged 18-35 years living in Durban, South Africa with personal or partner plans for pregnancy with a partner with HIV or of unknown serostatus. Participants were offered safer conception counseling, including daily oral PrEP; women who initiated PrEP were given a bottle with an electronic pillcap that recorded when device opens. Weekly adherence to daily PrEP was modeled using GBTM with a censored normal outcome distribution as a function of weeks since PrEP initiation. The number and functional form of the adherence trajectory groups were primarily selected based on Bayesian information criteria (BIC) and confirmed by mean estimated probabilities of group membership. A multivariable version of the selected model assessed baseline predictors of membership in adherence trajectory groups. Results: Overall mean (95% CI) adherence to PrEP was 63% (60%, 67%). We identified four groups of women with distinct patterns of adherence: (1) high (i.e., ≥6 doses per week) steady adherence throughout follow-up (22% of PrEP initiators); (2) moderate (i.e., 4-5 doses per week), but steady adherence (31%); (3) initially high, but consistently declining adherence (21%); and (4) initially moderate adherence, followed by a rapid decline and subsequent rebound (26%). In multivariable-adjusted analyses, older age was associated with membership in the high, steady adherence group as compared to the group identified with an adherence trajectory of initially high, then decline, and finally a rebound. Conclusions: GBTM is useful for exploring potential heterogeneity in longitudinal patterns of medication adherence. Although a large proportion of women in this study achieved high levels of adherence by electronic pillcap initially, far fewer women maintained these levels consistently. Knowledge of different adherence trajectories could be used to develop targeted strategies for optimizing HIV prevention during periconception.

RESUMO

Many adolescents and young adults with HIV (AYWH) struggle with antiretroviral therapy (ART) adherence and experience poorer outcomes than adults. Relevant factors include forgetfulness and poor self-efficacy related to their evolving neurobiology. We qualitatively explored experiences of AYWH-caregivers dyads using real-time ART adherence monitors and associated reminder functions in the home setting. As part of an implementation science-oriented study, AYWH used the Wisepill adherence monitor for 3 months. AYWH could also opt for short message service (SMS) self-reminders, a self-selected social supporter for delayed or missed doses, or an alarm reminder. We conducted in-depth interviews with randomly selected AYWH-caregiver dyads regarding their experience using the monitor. Qualitative data were analyzed using inductive content analysis. We completed 15 AYWH-caregiver dyad interviews. Of the AYWH, 67% were female, mean age was 16 years, 56% lived with their biological mother, and 86% were virologically suppressed. AYWH and their caregivers generally found the adherence monitors acceptable, though some had privacy concerns. AYWH felt the monitors helped them take charge of their medication, largely through the real-time alarm and SMS reminders; this took the burden of adherence reminders away from the caregivers, improving strained AYWH-caregiver relationships. Two adolescents reported rebound poor adherence after monitor withdrawal. ART adherence monitors and associated tools were largely acceptable to AYWH and their caregivers in home settings. The intervention helped improve AYWH self-efficacy and alleviated burden from some AYWH-caregiver relationships. Rebound poor adherence suggests the need for on-going support and/or other means to achieve intrinsic mechanisms for sustained adherence. Clinical Trial Registration number: NCT03825952.

RESUMO

BACKGROUND: There is an urgent need to increase diversity among scientific investigators in the HIV research field to be more reflective of communities highly affected by the HIV epidemic. Thus, it is critical to promote the inclusion and advancement of early-stage scholars from racial and ethnic groups underrepresented in HIV science and medicine. METHODS: To widen the HIV research career pathway for early-stage scholars from underrepresented minority groups, the National Institutes of Health supported the development of the Centers for AIDS Research (CFAR) Diversity, Equity, and Inclusion Pathway Initiative (CDEIPI). This program was created through partnerships between CFARs and Historically Black Colleges and Universities and other Minority Serving Institutions throughout the United States. RESULTS: Seventeen CFARs and more than 20 Historically Black Colleges and Universities and Minority Serving Institutions have participated in this initiative to date. Programs were designed for the high school (8), undergraduate (13), post baccalaureate (2), graduate (12), and postdoctoral (4) levels. Various pedagogical approaches were used including didactic seminar series, intensive multiday workshops, summer residential programs, and mentored research internship opportunities. During the first 18 months of the initiative, 257 student scholars participated in CDEIPI programs including 150 high school, 73 undergraduate, 3 post baccalaureate, 27 graduate, and 4 postdoctoral students. CONCLUSION: Numerous student scholars from a wide range of educational levels, geographic backgrounds, and racial and ethnic minority groups have engaged in CDEIPI programs. Timely and comprehensive program evaluation data will be critical to support a long-term commitment to this unique training initiative.

RESUMO

BACKGROUND: The underrepresentation of historically marginalized groups in the HIV research workforce is a barrier to reaching national Ending the Epidemic goals. SETTING: The Harvard University Center for AIDS Research (HU CFAR) Diversity Equity and Inclusion Working Group (DEI WG) uses a multifaceted approach to enhance the field's diversity. METHODS: We established a DEI WG to improve the recruitment, inclusion, and retention of underrepresented minorities (URMs) in HIV research. We use community-based, participatory processes to establish and expand education and outreach programs about HIV care and research to better connect the HU CFAR to communities affected by HIV. This article reports on the development of the WG in July 2022, progress in its first year, and future plans. RESULTS: We have built a network of >50 investigators across the university for monthly meetings; partnered with existing research pathway programs for high school, undergraduate, and graduate students, directly supporting 7 new trainees and linking CFAR investigators to additional mentorship opportunities; and created 2-year Scholar Awards for 5 URM investigators in HIV. Planned work includes needs assessments for early-stage investigators to understand factors contributing to inclusion and retention and new pathway and outreach programming being developed with community partner minority-serving institutions. CONCLUSIONS: The HU CFAR DEI WG strives to ensure that individuals from underrepresented, marginalized, and minoritized communities have an opportunity to contribute to HIV research and that research is informed by the needs of the communities affected by the epidemic. An intersectional approach should be incorporated into HIV research pathway initiatives.

RESUMO

BACKGROUND: In sub-Saharan Africa, increased antiretroviral therapy (ART) availability has improved survival after diagnosis of Kaposi sarcoma (KS) compared to the pre-ART era, but mortality among patients with KS is still considerably higher than HIV-infected persons without KS. Furthermore, among those patients with KS who are treated initially with ART without adjunct chemotherapy and who do survive, little is known about how well they function and feel - quality of life (QOL) - compared to those without KS. METHODS: Among HIV-infected adults initiating ART in two prospective studies in Uganda, we compared those presenting with KS to those without KS. QOL was measured using the Medical Outcomes Survey-HIV instrument prior to ART initiation and at 16, 32, and 48 weeks thereafter; higher scores indicate better QOL. To ascertain the independent effect of KS versus non-KS on 11 domains of QOL and two summary scores, we created mixed effects models adjusted for directed acyclic graph-informed confounders. RESULTS: We examined 224 participants with KS and 730 without KS, among whom 64% were women and median age was 34 years. Prior to ART initiation, participants had a median CD4+ T count of 159 cells/mm3 and plasma HIV RNA of 5.1 log10 copies/ml. In adjusted analyses prior to ART initiation, those with KS had lower mean scores in 8 of 11 QOL domains and both physical and mental health summary scores compared to those without KS. After 48 weeks of ART, those with KS had higher mean QOL scores compared those without KS in 4 domains and the mental health summary score, and lower scores in only one domain. There was no significant difference in 6 domains and the physical health summary score. CONCLUSIONS: Amongst HIV-infected adults in East Africa, at time of ART initiation, those with KS had worse mean QOL compared to those without KS. Over the first year of ART, those with KS became comparable to or exceeded those without KS in most QOL domains. The findings indicate that some patients with KS can be treated with ART alone and further emphasize the need to predict those who will do well with ART alone versus those who need additional initial therapy.

RESUMO

BACKGROUND: Tuberculosis(TB) is among the leading causes of infectious death worldwide. Contact investigation is an evidence-based, World Health Organisation-endorsed intervention for timely TB diagnosis, treatment, and prevention but has not been widely and effectively implemented. METHODS: We are conducting a stepped-wedge, cluster-randomised, hybrid Type III implementation-effectiveness trial comparing a user-centred to a standard strategy for implementing TB contact investigation in 12 healthcare facilities in Uganda. The user-centred strategy consists of several client-focused components including (1) a TB-education booklet, (2) a contact-identification algorithm, (3) an instructional sputum-collection video, and (4) a community-health-rider service to transport clients, CHWs, and sputum samples, along with several healthcare-worker-focused components, including (1) collaborative improvement meetings, (2) regular audit-and-feedback reports, and (3) a digital group-chat application designed to develop a community of practice. Sites will cross-over from the standard to the user-centred strategy in six, eight-week transition steps following a randomly determined site-pairing scheme and timeline. The primary implementation outcome is the proportion of symptomatic close contacts completing TB evaluation within 60 days of TB treatment initiation by the index person with TB. The primary clinical effectiveness outcomes are the proportion of contacts diagnosed with and initiating active TB disease treatment and the proportion initiating TB preventative therapy within 60 days. We will assess outcomes from routine source documents using intention-to-treat analyses. We will also conduct nested mixed-methods studies of implementation fidelity and context and perform cost-effectiveness and impact modelling. The Makerere School of Public Health IRB(#554), the Uganda National Council for Science and Technology(#HS1720ES), and the Yale Institutional Review Board(#2000023199) approved the study and waived informed consent for the main trial implementation-effectiveness outcomes. We will submit results for publication in peer-reviewed journals and disseminate findings to local policymakers and representatives of affected communities. DISCUSSION: This pragmatic, quasi-experimental implementation trial will inform efforts to find and prevent undiagnosed persons with TB in high-burden settings using contact investigation. It will also help assess the suitability of human-centred design and communities of practice for tailoring implementation strategies and sustaining evidence-based interventions in low-and-middle-income countries. TRIAL REGISTRATION: The trial was registered(ClinicalTrials.gov Identifier NCT05640648) on 16 November 2022, after the trial launch on 7 March 2022.

RESUMO

Area-based sociodemographic markers, such as census tract foreign-born population, have been used to identify individuals and communities with a high risk for tuberculosis (TB) infection in the United States. However, these markers have not been evaluated as independent risk factors for TB infection in children. We evaluated associations between census tract poverty, crowding, foreign-born population, and the CDC's Social Vulnerability Index (CDC-SVI) ranking and TB infection in a population of children tested for TB infection in Boston, Massachusetts. After adjustment for age, crowding, and foreign-born percentage, increasing census tract poverty was associated with increased odds of TB infection (adjusted odds ratio [aOR] per 10% increase in population proportion living in poverty: 1.20 [95% CI, 1.04-1.40]; P = 0.01), although this association was attenuated after further adjustment for preferred language. In separate models, increasing CDC-SVI ranking was associated with increased odds of TB infection, including after adjustment for age and language preference (aOR per 10-point increase in CDC-SVI rank: 1.08 [95% CI, 1.02-1.15]; P = 0.01). Our findings suggest area-based sociodemographic factors may be valuable for characterizing TB infection risk and defining the social ecology of pediatric TB infection in low-burden settings.

RESUMO

The COVID-19 pandemic has highlighted disparities in outcomes by social determinants to health. It is unclear how much end-of-life discussions and a patient's decision about code status ("do not resuscitate," do not resuscitate, or "comfort measures only," [CMO] orders) might contribute to in hospital disparities in care, especially given know racial inequities in end-of-life care. Here, we looked at factors associated with code status orders at the end of hospitalization for patients with COVID-19. We conducted a retrospective chart review of all patients who presented to the Emergency Department of a large quaternary hospital between 8 March and 3 June 2020. We used logistic regression modeling to quantify the degree to which social determinants of health, including race, ethnicity, area deprivation index (ADI), English as a primary language, homelessness, and illicit substance use might impact the likelihood of a particular code status at the end-of a patient's hospitalization, while controlling for disease severity. Among social determinants to health, only white race (odds ratio [OR] 2.0; P = .03) and higher ADI (OR 1.2; P = .03) were associated with having a do not resuscitate or a CMO order. Additionally, we found that patients with white race (OR 2.9; P = .02) were more likely to carry a CMO order. Patient race and ADI were associated with different code status orders at the end of hospitalization. Differences in code status might have contributed to disparities in COVID-19 outcomes early in the pandemic, though further investigations are warranted.
