The impact of Medicaid expansion under the Affordable Care Act on HIV care continuum outcomes across the United States.

HIV care continuum outcome disparities by health insurance status have been noted among people with HIV (PWH). We therefore examined associations between state Medicaid expansion and HIV outcomes in the United States. Adults (≥18 years) with ≥1 visit in NA-ACCORD clinical cohorts from 2012-2017 contributed person-time annually between first and final visit or death; in each calendar year, clinical retention was ≥2 completed visits > 90 days apart, antiretroviral therapy (ART) receipt was receipt of ≥3 antiretroviral agents, and viral suppression was last measured HIV-1 RNA < 200 copies/mL.

A simple phylogenetic approach to analyze hypermutated HIV proviruses reveals insights into their dynamics and persistence during antiretroviral therapy.

Hypermutated proviruses, which arise in a single HIV replication cycle when host antiviral APOBEC3 proteins introduce extensive G-to-A mutations throughout the viral genome, persist in all people living with HIV receiving antiretroviral therapy (ART). But, the within-host evolutionary origins of hypermutated sequences are incompletely understood because phylogenetic inference algorithms, which assume that mutations gradually accumulate over generations, incorrectly reconstruct their ancestor-descendant relationships. Using > 1400 longitudinal single-genome-amplified HIV sequences isolated from six women over a median 18 years of follow-up - including plasma HIV RNA sequences collected over a median 9 years between seroconversion and ART initiation, and > 500 proviruses isolated over a median 9 years on ART - we evaluated three approaches for removing hypermutation from nucleotide alignments.

Mild HIV-specific selective forces overlaying natural CD4+ T cell dynamics explain the clonality and decay dynamics of HIV reservoir cells.

The latent reservoir of HIV persists for decades in people living with HIV (PWH) on antiretroviral therapy (ART). To determine if persistence arises from the natural dynamics of memory CD4+ T cells harboring HIV, we compared the clonal dynamics of HIV proviruses to that of memory CD4+ T cell receptors (TCRβ) from the same PWH and from HIV-seronegative people. We show that clonal dominance of HIV proviruses and antigen-specific CD4+ T cells are similar but that the field's understanding of the persistence of the less clonally dominant reservoir is significantly limited by undersampling.

Frailty-Related Factors among Women Living with and without HIV Aged 40 Years and Older. The Women's Interagency HIV Study.

Background: Frailty is a clinical, geriatric syndrome linked to disability and mortality; and may be associated with a variety of factors among underrepresented and underserved women living with HIV (WLWH) and without HIV (WLWOH) transitioning through the adult life course.

Objectives: Determine whether a published set of factors associated cross-sectionally with frailty in WLWH and similar WLWOH at average age 39 years in 2005/2006 were associated with frailty in 2018/2019 among women who initiated frailty assessments at age ≥40 years, or whether a new set of factors were associated with frailty.

Design: Cross-sectional analyses within a longitudinal cohort study.

Prostatic urethral lift for subjects in urinary retention (PULSAR): 12-Month results of a prospective controlled trial compared with real-world outcomes.

Objective: To examine the safety and efficacy of prostatic urethral lift (PUL) in acute urinary retention (AUR) patients within a controlled (PULSAR) and real-world setting (Real-World Retrospective study).

Materials And Methods: PULSAR was a 12-month prospective study of PUL in AUR patients ( = 51) performed at six centres in the United Kingdom; enrolled BPH patients aged ≥50 years, with prostate volume of ≤100 cc. AUR was defined as being catheter dependent with at least one prior failed trial without catheter (TWOC) while on an alpha-blocker.

The replication-competent HIV reservoir is a genetically restricted, younger subset of the overall pool of HIV proviruses persisting during therapy, which is highly genetically stable over time.

Within-host HIV populations continually diversify during untreated infection, and members of these diverse forms persist within infected cell reservoirs, even during antiretroviral therapy (ART). Characterizing the diverse viral sequences that persist during ART is critical to HIV cure efforts, but our knowledge of on-ART proviral evolutionary dynamics remains incomplete, as does our understanding of the differences between the overall pool of persisting proviral DNA (which is largely genetically defective) and the subset of intact HIV sequences capable of reactivating. Here, we reconstructed within-host HIV evolutionary histories in blood from seven participants of the Women's Interagency HIV Study (WIHS) who experienced HIV seroconversion.

Plasma Glycomic Markers of Accelerated Biological Aging During Chronic HIV Infection.

People with HIV (PWH) experience an increased vulnerability to premature aging and inflammation-associated comorbidities, even when HIV replication is suppressed by antiretroviral therapy (ART). However, the factors that contribute to or are associated with this vulnerability remain uncertain. In the general population, alterations in the glycomes of circulating IgGs trigger inflammation and precede the onset of aging-associated diseases.

Glucocorticoid Receptor Function and Cognitive Performance in Women With HIV.

Objective: Alterations in glucocorticoid receptor (GCR) function may be a risk factor for cognitive complications among older people with human immunodeficiency virus (HIV). We evaluated whether HIV serostatus and age modify the GCR function-cognition association among women.

Methods: Eighty women with HIV ( n = 40, <40 years of age [younger]; n = 40, >50 years of age [older]) and 80 HIV-uninfected women ( n = 40 older, n = 40 younger) enrolled in the Women's Interagency HIV Study completed a comprehensive neuropsychological test battery.

Single cell transcriptomics and TCR reconstruction reveal CD4 T cell response to MHC-II-restricted APOB epitope in human cardiovascular disease.

Atherosclerosis is accompanied by a CD4 T cell response to apolipoprotein B (APOB). Major Histocompatibility Complex (MHC)-II tetramers can be used to isolate antigen-specific CD4 T cells by flow sorting. Here, we produce, validate and use an MHC-II tetramer, DRB1*07:01 APOB-p18, to sort APOB-p18-specific cells from peripheral blood mononuclear cell samples from 8 DRB1*07:01+ women with and without subclinical cardiovascular disease (sCVD).

Longitudinal Assessment of the Enhanced Liver Fibrosis Score in the Era of Contemporary HIV and Hepatitis C Virus Treatment.

Background: The trajectory of liver fibrosis is not well understood in the contemporary era of human immunodeficiency virus (HIV) and hepatitis C virus (HCV) therapy.

Methods: We assessed the Enhanced Liver Fibrosis (ELF) score, aspartate transaminase-to-platelet ratio index (APRI) and Fibrosis-4 (FIB-4) in 116 women with HIV/HCV coinfection over a 4-year period. Random-effects linear regression models examined the rate of fibrosis change 1-2 years before starting HCV treatment, within 1 year before starting (peri-HCV treatment), within 1 year after and 1-2 years post-HCV treatment in unadjusted and adjusted models including age, race, and changes from pretreatment of factors that might affect fibrosis (eg, alcohol, integrase strand inhibitor [INSTI] use, waist circumference, CD4 count).

Differences in Muscle Quantity and Quality by HIV Serostatus and Sex.

Objective: People with HIV (PWH) experience greater declines in both muscle function and muscle mass with aging. Whether changes in muscle quality and quantity with aging differ between men and women with HIV and the implications on muscle function are not established.

Design: In coordinated substudies of the Multicenter AIDS Cohort Study and Women's Interagency HIV Study, participants completed physical function and falls assessments; total trunk/thigh density, inversely related to fatty infiltration, and area were quantified from computed tomography (CT) scans.

Lung Function in Women With and Without Human Immunodeficiency Virus.

Background: Prior studies have found that human immunodeficiency virus (HIV) infection is associated with impaired lung function and increased risk of chronic lung disease, but few have included large numbers of women. In this study, we investigate whether HIV infection is associated with differences in lung function in women.

Methods: This was a cross-sectional analysis of participants in the Women's Interagency HIV Study, a racially and ethnically diverse multicenter cohort of women with and without HIV.

Visualizing the Geography of HIV Observational Cohorts With Density-Adjusted Cartograms.

Background: Maps are potent tools for describing the spatial distribution of population and disease characteristics and, thereby, for appropriately targeting public health interventions. People with HIV (PWH) tend to live in densely populated and spatially compact areas that may be difficult to visualize on maps using unadjusted geographic or political borders.

Setting: To illustrate these challenges, we used geographic data from adult PWH at the Vanderbilt Comprehensive Care Clinic (VCCC) in Nashville, Tennessee, and aggregated data from the North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD) from 1998 to 2015.

Examining the Relationships Between Experienced and Anticipated Stigma in Health Care Settings, Patient-Provider Race Concordance, and Trust in Providers Among Women Living with HIV.

Stigma in health care settings can have negative consequences on women living with HIV, such as increasing the likelihood of missed visits and reducing trust in their clinical providers. Informed by prior stigma research and considering knowledge gaps related to the effect of patient-provider race concordance, we conducted this study to assess if patient-provider race concordance moderates the expected association between HIV-related stigma in health care settings and patients' trust in their providers. Moderation analyses were conducted using Women's Interagency HIV Study data ( = 931).

Patient Health Literacy and Communication with Providers Among Women Living with HIV: A Mixed Methods Study.

In this mixed-methods study, we examine the relationship between provider communication and patient health literacy on HIV continuum of care outcomes among women living with HIV in the United States. We thematically coded qualitative data from focus groups and interviews (N = 92) and conducted mediation analyses with quantitative survey data (N = 1455) collected from Women's Interagency HIV Study participants. Four qualitative themes related to provider communication emerged: importance of respect and non-verbal cues; providers' expressions of condescension and judgement; patient health literacy; and unclear, insufficient provider communication resulting in diminished trust.

Discrimination and Calibration of the Veterans Aging Cohort Study Index 2.0 for Predicting Mortality Among People With Human Immunodeficiency Virus in North America.

Background: The updated Veterans Aging Cohort Study (VACS) Index 2.0 combines general and human immunodeficiency virus (HIV)-specific biomarkers to generate a continuous score that accurately discriminates risk of mortality in diverse cohorts of persons with HIV (PWH), but a score alone is difficult to interpret. Using data from the North American AIDS Cohort Collaboration (NA-ACCORD), we translate VACS Index 2.
