Immediate Antiretroviral Therapy: The Need for a Health Equity Approach
Immediate antiretroviral therapy (iART), defined as same-day initiation of ART or as soon as possible after diagnosis, has recently been recommended by global and national clinical care guidelines for patients newly diagnosed with human immunodeficiency virus (HIV). Based on San Francisco’s Rapid ART Program Initiative for HIV Diagnoses (RAPID) model, most iART programs in the US condense ART initiation, insurance acquisition, housing assessment, and mental health and substance use evaluation into an initial visit. However, the RAPID model does not explicitly address structural racism and homophobia, HIV-related stigma, medical mistrust, and other important factors at the time of diagnosis experienced more poignantly by African American, Latinx, men who have sex with men (MSM), and transgender patient populations. These factors negatively impact initial and subsequent HIV care engagement and exacerbate significant health disparities along the HIV care continuum. While iART has improved time to viral suppression and linkage to care rates, its association with retention in care and viral suppression, particularly in vulnerable populations, remains controversial. Considering that in the US the HIV epidemic is sharply defined by healthcare disparities, we argue that incorporating an explicit health equity approach into the RAPID model is vital to ensure those who disproportionately bear the burden of HIV are not left behind
Predictors of missed HIV screening opportunities among newly diagnosed individuals at an urban medical center in New York City, 2018-2022.
ObjectiveTo identify demographic and clinical factors predictive of having a missed opportunity (MO) for HIV screening.DesignRetrospective cohort study.MethodsElectronic medical records were queried for individuals newly diagnosed with HIV in different sites within a large urban academic medical center in New York City between 2018 and 2022. The primary outcome was having one or more MO for HIV screening within the institution, defined as any encounter at which screening was not performed in the 365 days preceding the HIV diagnosis.ResultsOver one third of new diagnoses had at least one MO in the preceding year. Older individuals, cisgender women and those assigned female sex at birth, and heterosexual individuals were more likely to have at least one MO. An initial CD4 ConclusionsThese findings suggest that populations perceived to be at lower risk for HIV are more likely to have MOs and possibly late diagnoses, and that universal HIV screening must be implemented into the workflows of emergency department and outpatient settings to facilitate early diagnosis and reduce the incidence of HIV
Impact of Physical Activity and Weight Loss on Fat Mass, Glucose Metabolism, and Inflammation in Older African Americans with Osteoarthritis
(1) Background: There are currently very few interventions performed within a community setting that compare the effects of physical activity (PA) versus PA plus weight loss on cancer and chronic disease risk in older African Americans. Therefore, we investigated the impact of an 8 week (24 session) PA intervention compared to a PA plus weight loss intervention on fat mass, glucose metabolism, and markers of inflammation in older, overweight and obese African Americans. (2) Methods: Subjects were randomized to a PA (n = 83) or PA plus weight loss (n = 72) intervention that met three times weekly for 8 weeks. At baseline and post-intervention, anthropometrics, body composition, systemic inflammation (high-sensitivity C-reactive protein, tumor necrosis factor-α, and interleukin 6), fasting glucose, insulin and homeostasis model assessment-insulin resistance (HOMA-IR) were determined. (3) Results: Subjects had a mean age of 67 years (SD = 5.3) and were mostly women (88%). The PA plus weight loss group lost more total and visceral fat than the PA group (−4.0% vs. +0.6% and −4.1% vs. +3.7%, respectively, p < 0.01 for both). Changes in inflammation and glucose metabolism were similar between groups post-intervention. Within the PA plus weight loss group only, serum insulin and HOMA-IR decreased significantly. (4) Conclusions: PA combined with weight loss can decrease total and visceral fat mass and improve insulin sensitivity, confirming that these cancer- and chronic disease-related risk factors are influenced by relatively modest lifestyle changes in the short term
Retained in HIV Care But Not on Antiretroviral Treatment: A Qualitative Patient-Provider Dyadic Study.
Patients retained in HIV care but not on antiretroviral therapy (ART) represent an important part of the HIV care cascade in the United States. Even in an era of more tolerable and efficacious ART, decision making in regards to ART offer and uptake remains complex and calls for exploration of both patient and provider perspectives. We sought to understand reasons for lack of ART usage in patients meeting the Health Resources Services Administration definition of retention as well as what motivated HIV primary care appointment attendance in the absence of ART.We conducted a qualitative study consisting of 70 in-depth interviews with ART-naĂŻve and ART-experienced patients off ART and their primary care providers in two urban safety-net HIV clinics in San Francisco and New York. Twenty patients and their providers were interviewed separately at baseline, and 15 dyads were interviewed again after at least 3 mo and another clinic visit in order to understand any ART use in the interim. We applied dyadic analysis to our data. Nearly all patients were willing to consider ART, and 40% of the sample went on ART, citing education on newer antiretroviral drugs, acceptance of HIV diagnosis, social support, and increased confidence in their ability to adhere as facilitators. However, the strength of the provider recommendation of ART played an important role. Many patients had internalized messages from providers that their health was too good to warrant ART. In addition, providers, while demonstrating patient-centered care through sensitivity to patients experiencing psychosocial instability, frequently muted the offer of ART, at times unintentionally. In the absence of ART, lab monitoring, provider relationships, access to social services, opiate pain medications, and acute symptoms motivated care. The main limitations of this study were that treatment as prevention was not explored in depth and that participants were recruited from academic HIV clinics in the US, making the findings most generalizable to this setting.Provider communication with regard to ART is a key focus for further exploration and intervention in order to increase ART uptake for those retained in HIV care
Changes in Glucose Homeostasis and Systemic Inflammation Following an 8-week Exercise Only and 8-week Exercise Plus Dietary Weight Management Intervention among Overweight and Obese African American Older Adults with Osteoarthritis
Â
Background. Obesity is associated with impaired fasting blood glucose, insulin resistance (IR) and low-grade in- flammation, all of which are risk factors for chronic diseases including type 2 diabetes (T2D). Glucose metabolism and inflammation can be modified with lifestyle changes, although few studies have examined the impact of behav- ioral lifestyle interventions conducted in a “real world” community-based setting on these parameters in overweight and obese older African American (AA) adults with osteoarthritis (OA). The aim of this study was to examine the impact of an 8-week exercise only and 8- week exercise plus dietary weight management intervention on glucose me- tabolism and systemic inflammation in older overweight and obese AA adults with pre-existing lower extremity OA.
Methods. Participants were randomized to an 8-week exercise-only (n=59) or exercise plus dietary weight manage- ment (n=48) intervention. Baseline and post-intervention body measures (weight, BMI, and percent body fat) and fasting serum glucose, serum insulin, high sensitivity C-reactive protein and interleukin-6 were assessed. The homeo- static model assessment of insulin resistance (HOMA-IR) was also calculated. Demographic and health-related data were obtained via questionnaire at baseline. Generalized estimating equations to compare changes from baseline ad- justed for BMI and Spearman’s correlation examining the relationship between change in body measures and change in inflammation and glucose metabolism were also examined.
Results. The participants were predominately female (86%) with mean age of 67.1 (± 5.6) years and mean BMI of 34 kg/m2 (95% Confidence Interval: 31.9 – 36.1 kg/m2). Participants in the exercise plus dietary weight management group lost significantly more weight on average than those in the exercise-only group (-2.0 vs. -0.1 kg; p
Conclusions. An 8-week exercise plus dietary weight management intervention has potential clinical relevance in regard to improving both body weight and glucose metabolism in a population at elevated risk for T2D and its related complications.

Remdesivir for Treatment of COVID-19 Requiring Oxygen Support: A Cross-Study Comparison from Two Large, Open-Label Studies
Background:
Remdesivir, an RNA-polymerase prodrug inhibitor approved for treatment of COVID-19, shortens recovery time and improves clinical outcomes. This prespecified analysis compared remdesivir plus standard-of-care (SOC) with SOC alone in adults hospitalized with COVID-19 requiring oxygen support in the early stage of the pandemic.
Methods:
Data for 10-day remdesivir treatment plus SOC from the extension phase of an open-label study (NCT04292899) were compared with real-world, retrospective data on SOC alone (EUPAS34303). Both studies included patients aged ≥18 years hospitalized with SARS-CoV-2 up to 30 May 2020, with oxygen saturation ≤94%, on room air or supplemental oxygen (all forms), and with pulmonary infiltrates. Propensity score weighting was used to balance patient demographics and clinical characteristics across treatment groups. The primary endpoint was time to all-cause mortality or end of study (day 28). Time-to-discharge, with a 10-day landmark to account for duration of remdesivir treatment, was a secondary endpoint.
Results:
1974 patients treated with remdesivir plus SOC, and 1426 with SOC alone, were included after weighting. Remdesivir significantly reduced mortality versus SOC (hazard ratio [HR]: 0.46, 95% confidence interval: 0.39–0.54). This association was observed at each oxygen support level, with the lowest HR for patients on low-flow oxygen. Remdesivir significantly increased the likelihood of discharge at day 28 versus SOC in the 10-day landmark analysis (HR: 1.64; 95% confidence interval: 1.43–1.87).
Conclusions:
Remdesivir plus early-2020 SOC was associated with a 54% lower mortality risk and shorter hospital stays compared with SOC alone in patients hospitalized with COVID-19 requiring oxygen support.
