Although mentoring is critical for career advancement, underrepresented minority (URM) faculty often lack access to mentoring opportunities. We sought to evaluate the impact of peer mentoring on career development success of URM early career faculty in the National Heart Lung and Blood Institute-sponsored, Programs to Increase Diversity Among Individuals Engaged in Health-Related Research-Functional and Translational Genomics of Blood Disorders (PRIDE-FTG). The outcome of peer mentoring was evaluated using the Mentoring Competency Assessment (MCA), a brief open-ended qualitative survey, and a semi-structured exit interview. Surveys were completed at baseline (Time 1), 6 months, and at the end of PRIDE-FTG participation (Time 2). The following results were obtained. Between Time 1 and Time 2, mentees’ self-assessment scores increased for the MCA (p < 0.01) with significant increases in effective communication (p < 0.001), aligning expectations (p < 0.05), assessing understanding (p < 0.01), and addressing diversity (p < 0.002). Mentees rated their peer mentors higher in the MCA with significant differences noted for promoting development (p < 0.027). These data suggest that PRIDE-FTG peer mentoring approaches successfully improved MCA competencies among URM junior faculty participants with faculty ranking peer mentors higher than themselves. Among URM faculty, peer mentoring initiatives should be investigated as a key strategy to support early career scholar development.

OBJECTIVES/SPECIFIC AIMS: The Clinical and Translational Science Award (CTSA) program is a national consortium of 50+ academic medical research centers charged with accelerating the translation of clinical research. In 2017, the NIH National Center for Advancing Translational Sciences anticipates total CTSA program funding of over $500M. The consortium’s hub-and-spoke structure makes it a natural dissemination network, and the newest funding announcement makes dissemination of innovation across the consortium an explicit goal, but characteristics of CTSA hubs as adopters and transmitters of innovation are unknown. METHODS/STUDY POPULATION: A content analysis was conducted using data from CTSA hub Web sites (n=64) and a structured coding taxonomy based on 6 constructs drawn from literature about diffusion of innovation in service organizations (Greenhalgh et al., 2004): dissemination priority, institutional complexity, communication infrastructure, support for dissemination/implementation functions, cross-institutional collaboration/networking, and leadership composition. RESULTS/ANTICIPATED RESULTS: In total, 52% of hubs will renew under the new PAR in the next few years, providing an incentive to demonstrate dissemination capacity (although hubs will likely lag in operationalizing these activities until they are funded). A third of hubs (34%) represent more than one academic/research institution, and almost 80% of hubs have more than one clinical affiliate. To accommodate these different levels of institutional complexity, broad diffusion will require multi-modal, locally adapted dissemination efforts. Only 25% of hubs have capacity to undertake additional dissemination activities, and only 27% provide formal D&I support, suggesting that additional capacity/support will be needed to operationalize the CTSA dissemination mission. In total, 30% of hubs participate in cross-institutional collaboration/networking, so many may not have existing norms/tools supporting inter-institutional collaboration, but 77% include leadership from outside the School of Medicine, facilitating effective intrainstitutional dissemination. DISCUSSION/SIGNIFICANCE OF IMPACT: Understanding more about CTSA hubs as both adopters and transmitters of innovation can facilitate strategic use of these sites as a built-in dissemination network to amplify the reach and impact of clinical innovation and improve population health. Based on this initial analysis, the CTSA network does not appear to be fully primed for broad, rapid dissemination of innovation across its sites. In-depth interviews are being conducted to investigate CTSA hubs’ perceptions of their dissemination capacity and roles as adopters and transmitters of innovation.

Community involvement in research is key to translating science into practice, and new approaches to engaging community members in research design and implementation are needed. The Community Scientist Program, established at the MD Anderson Cancer Center in Houston in 2018 and expanded to two other Texas institutions in 2021, provides researchers with rapid feedback from community members on study feasibility and design, cultural appropriateness, participant recruitment, and research implementation. This paper aims to describe the Community Scientist Program and assess Community Scientists' and researchers' satisfaction with the program. We present the analysis of the data collected from 116 Community Scientists and 64 researchers who attended 100 feedback sessions, across three regions of Texas including Northeast Texas, Houston, and Rio Grande Valley between June 2018 and December 2022. Community Scientists stated that the feedback sessions increased their knowledge and changed their perception of research. All researchers (100%) were satisfied with the feedback and reported that it influenced their current and future research methods. Our evaluation demonstrates that the key features of the Community Scientist Program such as follow-up evaluations, effective bi-directional communication, and fair compensation transform how research is conducted and contribute to reducing health disparities.

The Translational Science TS22 conference in Chicago in April 2022 was the first time post-pandemic that members of the Association of Clinical and Translational Science were able to meet up in person to share scientific advances. Given the remaining level of risk due to COVID-19, the meeting was designed as hybrid allowing virtual participation to some of the presentations. Prior to the meeting, JCTS Junior Editors were invited to report on the plenary sessions of the meeting. The present perspective constitutes a summary of three plenary sessions.

OBJECTIVES/GOALS: While CTSA hubs have contributed to the successes in COVID-19 clinical research, understanding the role of the CTSA consortium in translating vaccine efficacy and availability to awareness and implementation. The goal of this study is to quantitatively assess the use of social media in the dissemination of COVID 19 vaccine content across 60+ CTSA Hubs. METHODS/STUDY POPULATION: Structured search terms in the CTSA Search Solutions database were used to identify CTSA Hub website pages highlighting “COVID-19 Vaccination Information.” Each link identified was manually reviewed for vaccination content. The links and content identified by CTSA Search Solutions were then validated by advanced Google search operator “vaccine site” and manual review of CTSA Hub websites. Official CTSA Hub social media platforms were searched for vaccine proliferation content from January 1, 2020 to November 11, 2021. Data points collected included Community Targeted Vaccine Content, Vaccine Awareness, Vaccine Distribution, Vaccine Clinical Trial, Vaccine Related Media, Social Media Presence, and Social Media Vaccine Proliferation. RESULTS/ANTICIPATED RESULTS: In examining content, of the 64 listed CTSA Hubs, 52 of (67.2%) hosted one or more categories of COVID-19 vaccine information, and 16 (25%) hosted three or more categories. The most common category was “Community Targeted Information” with 27 (42.2%) hubs; the least common category was “Vaccine Distribution” with 5 (7.8%) hubs. Examining social media for vaccine proliferation, 41 (64.1%) hubs had connected social media and 23 (35.9%) hubs had vaccine proliferation posts. The most common platform was Twitter with 37 hubs; the least common platform was Instagram with 5 hubs. DISCUSSION/SIGNIFICANCE: Our investigation demonstrated varying Phase 4 translational efforts via social media among the CTSA Hubs for COVID-19 vaccine implementation. These novel findings identify promising opportunities for enhancement while emphasizing proven strategies from CTSA hubs nationwide. Further research will elucidate granular trends among CTSA hubs.

OBJECTIVES/GOALS: Understanding the mechanism of transcriptional adaptation may contribute to an explanation for variation in clinical manifestations of Amyotrophic lateral sclerosis patient phenotypes. METHODS/STUDY POPULATION: To examine transcriptional adaptation, we utilized gene editing tools in HT1080 cells and patient samples with known CHCHD10 mutations causative for Amyotrophic lateral sclerosis. Frameshift mutations were performed via CRISPR-Cas9. Ribonucleoprotein electroporation was used to transfect cells and DNA sequencing was conducted to validate gene editing. To validate transcriptional adaption, changes in levels of protein and gene expression will be measured via immunoblot and quantification of CHCHD10 and CHCHCD2 from whole cells lysates of the edited cells. RESULTS/ANTICIPATED RESULTS: We anticipate that CHCHD2 transcriptional adaptation can functionally compensate for the locus loss of function of CHCHD10. This mechanism of transcriptional adaptation may contribute to an explanation for variation in clinical manifestations of patient phenotypes. DISCUSSION/SIGNIFICANCE: Our approach would advance discovery science towards by exploring CHCHD10/2 transcriptional adaptation mechanism that can lead to novel therapies for rare Amyotrophic lateral sclerosis, such as CHCHD10-R15L.

OBJECTIVES/SPECIFIC AIMS: Identify objective neurological substrates of cognitive fatigue in Parkinson’s disease and in aging. METHODS/STUDY POPULATION: Structural and diffusion MRI. Behavioral assessments for aged adults and Parkinson’s disease. RESULTS/ANTICIPATED RESULTS: Gray and white matter deficits that correlate with deficits in the basal ganglia for fatigued Parkinson’s disease patients Versus anterior cingulate cortex in healthy aged adults with fatigue. DISCUSSION/SIGNIFICANCE OF IMPACT: Over 50% of patients with Parkison’s disease and 38% of healthy older adults suffer from cognitive fatigue. However, diagnostics are limited to subjective surveys and there are no treatments for either population. Therefore, objective measures are greatly needed for better diagnosis and development of treatment targets.

OBJECTIVES/GOALS: Women with diabetes (DM) have higher rates of unplanned pregnancy and pregnancy complications, indicating a need for DM-specific counseling. Our aim is to use the Health Belief Model (HBM), widely applied to DM interventions, to create a conceptual model of contraceptive decision-making for women with DM. METHODS/STUDY POPULATION: Our convergent mixed methods study integrates quantitative survey data and qualitative interview data from women aged 18-50 with DM. We will interview until theoretical saturation is achieved. Descriptive statistics will be calculated to summarize demographics, health history, and contraceptive use and knowledge. Using a grounded theory approach, qualitative analysis will be conducted by JW and EJ with special focus on exploring HBM constructs. A joint display will be used to integrate key quantitative variables by qualitative themes. Finally, we will aim to implement these HBM constructs within the context of contraceptive decision-making for women with DM. RESULTS/ANTICIPATED RESULTS: To date, we have interviewed 16 women with average age of 35 and an equal mix of type 1 vs. type 2 DM and those who identify their health as poor/fair vs. good/very good. The following HBM domains have emerged as relevant to contraceptive decision-making: perceived threats, perceived barriers, cues to action and self-efficacy. An analysis of the cues to action domain suggests that patients’ responses to provider counseling are substantially dependent on provider tone and awareness of patient context. Effective cues were delivered supportively with focus on health promotion, while ineffective cues focused on adverse outcomes or were delivered to women not at risk of pregnancy. DISCUSSION/SIGNIFICANCE OF IMPACT: The application of the HBM to contraceptive decision making among women with DM will provide insight into critical factors that inform both patient and provider attitudes and behaviors and can be targeted for future interventions to reduce unplanned pregnancy in this vulnerable population.

OBJECTIVES/GOALS: The major objective of this project is two points. First, is to repeat and confirm previous observations that there is elevated cytosolic Line1 DNA in the cytoplasm of cells derived from old mice compared to young. Second is to identify which Line1s in the genome are contributing to this free DNA and test if targeting them rescues the age-related phenotype. METHODS/STUDY POPULATION: This project will focus on data collected from both tissues and primary cells derived from multiple tissues. Using cellular/tissue fractionation kits, we isolate specifically from the cytoplasm. This specificity is confirmed by western blotting. Measurement of the Line1 levels is measured by quantitative PCR. Subsequently, these cytoplasmic samples are sent off for sequencing in order to quantify the length of the free DNA in the cytoplasm and to identify which Line1 genomic families the cytosolic DNA originates. Additionally, FISH is utilized to visualize Line1 DNA in the cytoplasm of aged versus young cells RESULTS/ANTICIPATED RESULTS: We anticipate this research to confirm the hypothesis that extranuclear Line1 DNA accumulates with age in both tissues and primary fibroblasts. Additionally, we expect to be able to determine which specific families of genomic Line1 is driving this extranuclear DNA, which would suggest the active retrotransopable elements that are directly involved in this aging related phenotype. Assuming successful identification of such families, we can then target and silence these specific elements to determine not only if cytoplasmic Line1 in aged mice decreases, but additionally if the healthspan and/or lifespan of these mice improves DISCUSSION/SIGNIFICANCE: Dereoressed Line1s have been shown to be involved in detrimental phenotypes, including autoimmune disease, cancer, and inflammaging. Targeting retrotransposons, either directly through degradation of transcriptional product of LINE1s or indirectly by improving function of regulators, will be crucial in ablating aging phenotypes

OBJECTIVES/SPECIFIC AIMS: Prostate cancer (PCa) is the most common noncutaneous malignancy in men in the United States. A significant fraction of advanced PCa treated with androgen deprivation therapy experience relentless progression to lethal metastatic castration-resistant prostate cancer (mCRPC). The PCa tumor microenvironment is comprised of a complex mixture of epithelial and stroma cell types engaged in multifaceted heterotypic interactions functioning to maintain tumor growth and immune evasion. We recently uncovered the important role played by myeloid-derived suppressor cells (MDSCs) to mediate tumor immune evasion in aggressive PCa (Wang, Lu et al., Cancer Discovery, 2016). Immune checkpoint blockade (ICB) has elicited durable therapeutic responses across a number of cancer types. However, the impact of ICB on mCRPC has been disappointing, which may signal the need to combine mechanistically-distinct ICB agents and/or override immunosuppression in the tumor microenvironment. Our objective is to determine if robust immunotherapy responses in mCRPC may be elicited by the combined actions of ICB agents together with targeted agents that neutralize MDSCs yet preserve T cell function. METHODS/STUDY POPULATION: We created a novel embryonic stem cell-based chimeric mouse model of mCRPC engineered with signature mutations to study the response to single and combination immunotherapy. The efficacy studies were followed with detailed mechanistic investigation and clinical validation. RESULTS/ANTICIPATED RESULTS: Consonant with early stage clinical trials experience, anti-CTLA4 or anti-PD1 monotherapy failed to impact disease progression. Similarly, modest anti-tumor activity was observed with combination ICB as well as monotherapy with targeted agents including Cabozantinib (tyrosine kinase inhibitor), Dactolisib (PI3K/mTOR inhibitor), and Dasatinib (tyrosine kinase inhibitor). In contrast, mCRPC primary and metastatic disease showed robust responses to dual ICB treatment together with either Cabozantinib or Dactolisib, but not with Dasatinib which impaired T cell infiltration in the tumor. Detailed intratumoral immune profiling with mass cytometry (CyTOF) showed that combined ICB and Cabozantinib or Dactolisib was associated with significant depletion of MDSCs. Cabozantinib and Dactolisib blocked the PI3K signaling activity in MDSCs and reduced their immunosupppresive activity. Mechanistically, the combination efficacy was due to the upregulation of IL-1RA and suppression of MDSC-promoting cytokines secreted by mCRPC cells. DISCUSSION/SIGNIFICANCE OF IMPACT: We demonstrated that an antibody cocktail targeting CTLA4 and PD1 was insufficient to generate effective anti-tumor response, but combination of ICB with targeted therapy that inactivates PI3K signaling displayed superior synergistic efficacy through impairing MDSCs in the tumor microenvironment. These observations illuminate a clinical path hypothesis for combining ICB with MDSC-targeted therapies in the treatment of mCRPC. Importantly, conclusions from the study on PCa may have implications in combination immunotherapy for aggressive breast cancer which is also largely resistant to immune checkpoint blockade and replete with immunosuppressive myeloid cells.

OBJECTIVES/SPECIFIC AIMS: To study the rate of recruitment to the Pulmonary Research Registry (PRR) at the University of Chicago using HealtheRx recruitment Versus usual practice. METHODS/STUDY POPULATION: CommunityRx is a health information technology, integrated with electronic medical record (EMR) platforms, that generates personalized referrals (“HealtheRxs”) for community-based programs and services that address basic and other health-related self-care needs. The target population included people ages 18 and older, English speaking, living in 1 of 16 ZIP codes on Chicago’s south and west sides (106 mi2) who received care at ≥1 of 28 CommunityRx partner sites and had a diagnosis of asthma or COPD. Between December 2015 and December 2016, information about pulmonary research participation opportunities was included on the HealtheRxs of eligible patients contemporaneously with usual registry recruitment methods. Usual methods, used since 2010 by the PRR group, included public advertisements requiring the patient to call the research team for more information and education of eligible patients identified during routine clinical care with a Pulmonary/Critical Care clinician or when enrolling in a pulmonary clinical trial. We hypothesized that, compared with usual recruitment practices, the HealtheRx recruitment strategy would increase the rate and decrease the per subject cost of patient recruitment to a prospective registry. Total annual recruitment costs for each method were calculated and divided by the number of consented PRR enrollees per method. RESULTS/ANTICIPATED RESULTS: Between December 22, 2015 and December 15, 2016 13,437 HealtheRxs (8762 for asthma, 3842 for COPD, and 833 for both asthma and COPD) were generated with the recruitment advertisement. In total, 41 patients responded to the ad and participated in the phone survey. In which 15 (36.5%) participants self-reported a diagnosis of asthma only (65% of all HealtheRxs with advertisement were for asthma only), 9 (22%) reported a diagnosis of COPD only (28.5% of all HealtheRxs with advertisement were for COPD only), and 17 (41.5%) reported diagnoses of both asthma and COPD (6.2% of all HealtheRxs with advertisement were for asthma and COPD). Most participants were female (n=28), non-Hispanic black (n=37), and not employed (n=39). The median age was 57. The majority (n=31) had never participated in health or medical research and was not aware of current opportunities to participate in research (n=25). All 41 participants expressed interest in joining PRR and were mailed a blank PRR consent form and a prepaid return envelope with their incentive check for the telephone survey. To date, 5 participants returned a signed consent form via mail and were enrolled in PRR. During the same period, 4 patients enrolled in PRR via usual recruitment methods. The cost per subject to enroll in PRR was $364.40 using the HealtheRx recruitment and $4590 using usual practice. DISCUSSION/SIGNIFICANCE OF IMPACT: NIH has called for innovation in research recruitment methodologies to increase enrollment especially of people who are under-represented in clinical trials research. This study demonstrates the feasibility and efficiency of using an EMR-integrated recruitment method to enroll people of under-represented minority groups to a research registry.

Navigating the research domain at an academic medical center can be challenging, even for seasoned investigators. To address this, Duke University launched two initiatives: (1) a research navigation “hotline” to provide brief assistance with a variety of research questions; and (2) researcher onboarding and consultation, a one-to-one tailored offering to ensure that researchers are equipped to navigate research resources and processes effectively. The services are provided by the myRESEARCHnavigators (MRN) team, funded by Duke’s CTSA. The diverse scientific backgrounds of the six team members align well with those of the research community, allowing for a good match between the researcher and MRN team member. The MRN team answers approximately 30 questions per month, and has provided consultations to almost 400 researchers. Both services receive high satisfaction ratings (4 or 5 stars [out of 5 stars] given to 90% of hotline answers, and 99% of researcher onboarding/consultation sessions). As of July 2019, the School of Medicine has determined that the consultations are critical to their mission and have made them a requirement for new research faculty. The team will continue marketing both services to encourage adoption.

OBJECTIVES/SPECIFIC AIMS: Stakeholder engagement has been proposed to help realign clinical and translational research with the needs of clinicians, patients, and policymakers. Increasingly, funders and researchers seek to partner with stakeholders to inform study design, execution and dissemination of results. Kids and families Impacting Disease through Science (KIDS) is a program of the American Academy of Pediatrics that seeks to engage youth in clinical research. United States KIDS programs participate in International Children’s Advisory Network activities. The Chicago KIDS Advisory Board program at Walter Payton College Preparatory School, a Chicago Public School, was initiated in 2015 to foster and develop interest in careers in science, research and healthcare and provide youth perspectives to academic and industry researchers on the design and development of pediatric research studies. This project engaged youth advisors in creation and evaluation of a video explaining clinical research and informed consent for Ann & Robert H. Lurie Children’s Hospital, a clinical partner of the Northwestern University Clinical and Translational Sciences Institute. METHODS/STUDY POPULATION: The Payton program advisory board sessions are 1.5hr interactive seminars held on 1–2 school days each month. During the 2016–2017 school year, students participated in 3 stakeholder sessions, led by Lurie Children’s hospital researchers, to advise development of a script, storyboards, and ultimately an animated video that informs children and families about participation in clinical research to aid in the decision-making process. Qualitative research methods were used to examine attitudes towards clinical research and assess the video on content objectives, clarity of concept, and appropriateness for a pediatric audience. Following production, students from the 2017–2018 advisory board viewed the final video and presurvey and postsurvey were administered to assess the effect of video on the comprehension of 8 key concepts of informed consent on a 5-point Likert scale. The Wilcoxon signed-rank test was used to compare median pretest and post-test ranks. Results of this analysis were reviewed in seminar and students provided written contribution to this abstract. RESULTS/ANTICIPATED RESULTS: In total, 11 Walter Payton high school students participated in video development and 27, who were naïve to development, participated in the pre and post evaluation sessions. Students ranged from Freshman to Seniors and reflected the diverse ethnic and racial background of Chicago. A positive change from pre to post-test survey was observed in all questions presented assessing comprehension of key concepts of informed consent. The median post-test ranks were statistically significantly higher than the median pre-test ranks for all questions (p<0.01 in all). DISCUSSION/SIGNIFICANCE OF IMPACT: Chicago KIDS youth advisors were engaged in all aspects of the design of the research tool and gained experience in stakeholder contribution from study design to evaluation and publication. The students will next be involved in the design of a prospective randomized study to test the efficacy of the video compared with standard recruitment and consent practices. Given the difficulty of recruiting youth for clinical trials, development of effective engagement practices in is critically important. Our findings demonstrate the feasibility of utilizing youth advisors in a public school based setting.

OBJECTIVES/GOALS: Chronic or new symptoms after infection with severe-acute-respiratory-coronavirus-2 (SARS-CoV-2) has been termed post-acute sequelae of Covid-19 (PASC) or Long Covid. Our objective is to present results from COVID-OUT, a phase 3 double-blind, randomized controlled trial of early outpatient treatment of Covid-19 with repurposed medications. METHODS/STUDY POPULATION: COVID-OUT enrolled adults age 30 to 85 with overweight or obesity who had proof of SARS-CoV-2 infection and fewer than 7 days of symptoms. In this 2 by 3 factorial design trial of metformin, ivermectin, fluvoxamine, or exact-matching placebo of each medication, participants were randomized 1:1:1:1:1:1 to the 6 treatment allocations. This abstract focuses on whether early treatment with metformin prevented Long Covid. Immediate release metformin was titrated to 1500mg daily over the first 6 days. We assessed the incidence of clinician-diagnosed Long Covid with follow up through 10 months after enrollment. We also assessed where participants were diagnosed with Long Covid, and where they received Long Covid treatment. RESULTS/ANTICIPATED RESULTS: Of 1124 participants, 98 (8.7%) report having a healthcare provider make a diagnosis of long covid. By arm, 6.9% (39/564) of metformin participants report having a diagnosis for long covid as compared with 10.5% (59/560) of matched placebo controls. The absolute reduction attributable to metformin was 3.6% (95%CI, 0.3% to 7.0%; P=0.031) with a relative risk reduction of 34% (95%CI, 3% to 55%). The metformin cost per long covid case averted was $28 (95%CI, $15 to $306). 10-month follow-up data will be available at the time of presentation as well as an analysis of baseline factors associated with the development of Long-Covid, independent of treatment allocation in the trial. DISCUSSION/SIGNIFICANCE: Metformin reduced the incidence of clinician-diagnosed long covid by 34% in a double-blind randomized placebo-controlled trial, and previous research published in-vitro activity by metformin against SARS-CoV-2 and other RNA viruses. Further investigation of metformin as early treatment for SARS-CoV-2 is warranted.

OBJECTIVES/GOALS: METHODS/STUDY POPULATION: This study utilizes the IeDEA W. Africa cohort to evaluate the prevalence and burden of hypertension and diabetes type II among people living with HIV (PLWH) in sub-Saharan Africa (SSA), and to assess how sex and aging impact the development of these NACM. The cohort is a large, international collaboration across eight countries and 19 treatment centers. Established by the National Institute of Allergy and Infectious Diseases in 2006, the W. Africa cohort is now in its fourth renewal (2021-2026). Participating countries include Senegal, Mali, Cote d’Ivoire, Burkina Faso, Ghana, Togo, Benin, and Nigeria. Data are collected from affiliated cohorts in the regional data center every 24 months. The cohort currently includes >65,000 adult PLWH on anti-retroviral therapy. RESULTS/ANTICIPATED RESULTS: The prevalence of several NACM, such as hypertension and cardiovascular disease, have significantly increased among PWH over time, surpassing prevalence observed in the general population. We therefore expect similar patterns in the W. Africa IeDEA cohort and a high prevalence and burden of both hypertension and diabetes type II in this sample. Additionally, evidence suggests that increasing age and female sex serve as independent risk factors for the development of NACM in PLWH. We anticipate that both increased age and female sex, separately and synergistically, are associated with increased prevalence and burden of hypertension and diabetes type II in this cohort. DISCUSSION/SIGNIFICANCE: With more than 37 million people currently living with HIV, the HIV/AIDS epidemic continues to pose a serious threat to global public health. SSA bears a disproportionate burden of the epidemic with greater than two-thirds of global cases. NACM are now driving morbidity and mortality among PLWH, and increased age and female sex may modify this effect.
