Background: Guidelines recommend annual anal cytology-based squamous cell carcinoma of anus (SCCA) screening for men who have sex with men (MSM) with HIV aged ≥35 years (eligible population). Recommended threshold for high resolution anoscopy (HRA) depends on its availability: low-threshold (any abnormal cytology) if availability is high, and high-threshold (High-Grade Squamous Intraepithelial Lesion (HSIL) on cytology) if availability is low.

Methods: Retrospective chart review (2018-2022) at academic HIV clinics.

The central nervous system HIV reservoir is incompletely understood and is a major barrier to HIV cure. We profiled people with HIV (PWH) and uninfected controls through single-cell transcriptomic and T cell receptor (TCR) sequencing to understand the dynamics of HIV persistence in the CNS. In PWH on ART, we found that most participants had single cells containing HIV-1 RNA, which was found predominantly in CD4 central memory T cells, in both cerebrospinal fluid (CSF) and blood.

Physical activity is associated with improved health outcomes among people with HIV (PWH). In the recent pandemic context, policies designed to mitigate COVID-19 transmission may result in an increase in sedentary lifestyle and decreased physical activity. In this study, we aimed to characterize self-reported physical activity and factors associated with physical inactivity during the first wave of the COVID-19 pandemic among a sample of PWH engaged in care.

Dectin-1 is an innate immune receptor that recognizes and binds β-1, 3/1, 6 glucans on fungi. We evaluated Dectin-1 function in myeloid cells in a cohort of HIV-positive and HIV-negative young and older adults. Stimulation of monocytes with β-D-glucans induced a pro-inflammatory phenotype in monocytes of HIV-infected individuals that was characterized by increased levels of IL-12, TNF-α, and IL-6, with some age-associated cytokine increases also noted.

In response to longstanding healthcare inequities unmasked by the Coronavirus Disease 2019 pandemic, the infectious diseases (ID) section at the Yale School of Medicine designed and implemented a pilot curriculum integrating Infectious Disease Diversity, Equity, and Antiracism (ID2EA) into ID educational training and measured program outcomes. We herein describe a mixed-methods assessment of section members on whether the ID2EA curriculum affected their beliefs and behaviors regarding racism and healthcare inequities. Participants rated the curriculum as useful (92% averaging across sessions) and effective in achieving stated learning objectives (89% averaging across sessions), including fostering understanding of how inequities and racism are linked to health disparities and identifying strategies to effectively deal with racism and inequities.

Background: Approximately 215 million Americans have been fully vaccinated for COVID-19, representing over 65% of the total population. People with HIV (PWH) may be more susceptible to COVID-19 infection or severe disease, elevating the importance of COVID-19 vaccination uptake in the population. We report results from a national survey of PWH to evaluate the likelihood of receiving a COVID-19 vaccine.

Background: The Ryan White (RW) program funds medical and other support services for low-income persons with HIV, significantly improving progress along the HIV care continuum. Although the program has shown overall improvements in achievement of viral suppression, the relative contributions of changes in clinical practice and RW service components to the optimization of the HIV care continuum, particularly for those with new HIV diagnoses, remain unknown.

Methods: The target population was patients with recent HIV diagnoses who received care at RW-funded clinics in the greater New Haven area between 2009 and 2018.

Objectives: Effective and safe COVID-19 vaccines have been developed and have resulted in decreased incidence and severity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and can decrease secondary transmission. However, there are concerns about dampened immune responses to COVID-19 vaccination among immunocompromised patients, including people living with HIV (PLWH), which may blunt the vaccine's efficacy and durability of protection. This study aimed to assess the qualitative SARS-CoV-2 vaccine immunogenicity among PLWH after vaccination.

As the Coronavirus-2019 (COVID-19) pandemic continues, multiple therapies are rapidly being evaluated for efficacy in clinical trials. Clinical trials should be racially and ethnically representative of the population that will eventually benefit from these medications. There are multiple potential barriers to racial and ethnic minority enrollment in clinical trials, one of which could be that inclusion and exclusion criteria select for certain racial or ethnic groups disproportionately.
