Uptake of HIV Preexposure Prophylaxis Among Medicare Beneficiaries - United States, 2014-2021.

Background: Previous studies have estimated preexposure prophylaxis (PrEP) use among persons with commercial health insurance and Medicaid. However, data are lacking regarding PrEP use among those with Medicare.

Methods: Using a previously developed algorithm, we estimated the number of Medicare beneficiaries (MBs) with fee-for-service (FFS) claims who were prescribed PrEP from 2014 to 2021.

Trends in Mental, Behavioral, and Developmental Disorders Among Children and Adolescents in the US, 2016-2021.

Introduction: Childhood mental, behavioral, and developmental disorders (MBDD) are common and are associated with poor health and well-being. Monitoring the prevalence of MBDDs among children and factors that may influence health outcomes is important to understanding risk and promoting population health.

Method: We examined trends in parent-reported lifetime MBDDs among children and associated health promotion and risk indicators from 2016 through 2021 by using data from the National Survey of Children's Health.

Access to and utilisation of COVID-19 antigen rapid diagnostic tests (Ag-RDTs) among the general population in Phnom Penh: a cross-sectional study.

Objectives: Globally, there is a lack of evidence regarding access to and utilisation of antigen rapid diagnostic tests (Ag-RDTs). This might hinder public health interventions to increase testing. We conducted a survey to understand access to and utilisation of COVID-19 Ag-RDT among residents in Phnom Penh, Cambodia.

Updated Recommendation for Universal Hepatitis B Vaccination in Adults Aged 19-59 Years - United States, 2024.

Hepatitis B (HepB) vaccines have demonstrated safety, immunogenicity, and efficacy during the past 4 decades (1,2). The Advisory Committee on Immunization Practices recommends universal HepB vaccination for adults aged 19-59 years, including pregnant persons, and adults aged ≥60 years with risk factors for hepatitis B. Adults aged ≥60 years without known risk factors for hepatitis B may also receive HepB vaccines (2).

SHIV remission in macaques with early treatment initiation and ultra long-lasting antiviral activity.

Studies in SIV-infected macaques show that the virus reservoir is particularly refractory to conventional suppressive antiretroviral therapy (ART). We posit that optimized ART regimens designed to have robust penetration in tissue reservoirs and long-lasting antiviral activity may be advantageous for HIV or SIV remission. Here we treat macaques infected with RT-SHIV with oral emtricitabine/tenofovir alafenamide and long-acting cabotegravir/rilpivirine without (n = 4) or with (n = 4) the immune activator vesatolimod after the initial onset of viremia.

Infodemics and Vaccine Confidence: Protocol for Social Listening and Insight Generation to Inform Action.

Background: In the fall of 2020, the COVID-19 infodemic began to affect public confidence in and demand for COVID-19 vaccines in the United States. While polls indicated what consumers felt regarding COVID-19 vaccines, they did not provide an understanding of why they felt that way or the social and informational influences that factored into vaccine confidence and uptake. It was essential for us to better understand how information ecosystems were affecting the confidence in and demand for COVID-19 vaccines in the United States.

Validation of a Simplified Laboratory-Based HCV Clearance Definition Using New York City Hepatitis C Program and Surveillance Data.

Context: Laboratory-based hepatitis C virus (HCV) clearance cascades are an important tool for health departments to track progress toward HCV elimination, but a laboratory-based definition of HCV clearance has not yet been validated.

Objective: To compare agreement between a laboratory-based HCV clearance definition with a clinical cure definition.

Design: Observational.

Leveraging HIV self-testing to achieve the UNAIDS 2025 targets in the South and Southeast Asia region.

Introduction: The South and Southeast Asia region has the second-highest number of people living with HIV globally. Despite progress in reducing HIV incidence and AIDS-related deaths, the region still has a long way to go in achieving the Joint United Nations Programme on HIV and AIDS (UNAIDS) 95-95-95 HIV testing, treatment and viral suppression targets. HIV self-testing (HIVST) is recommended by the World Health Organization as an additional approach to HIV testing.

Closing the Dissemination Gap: Accessible Toolkits for the Rapid Replication of Evidence-Informed Interventions to Improve Health Outcomes Among People with HIV.

Despite advances in HIV care and treatment in the U.S., disparities in outcomes along the HIV care continuum persist.

The effects of HIV self-testing on HIV incidence and awareness of status among men who have sex with men in the United States: Insights from a novel compartmental model.

Background: The OraQuick In-Home HIV self-test represents a fast, inexpensive, and convenient method for users to assess their HIV status. If integrated thoughtfully into existing testing practices, accompanied by efficient pathways to formal diagnosis, self-testing could enhance both HIV awareness and reduce HIV incidence. However, currently available self-tests are less sensitive, particularly for recent infection, when compared to gold-standard laboratory tests.

Racial and Ethnic Disparities in HIV Diagnosis Rates by Social Determinants of Health at the Census Tract Level among Adults in the United States and Puerto Rico, 2021.

Background: To compare racial and ethnic disparities in HIV diagnosis rates among adults in census tracts with most disadvantaged vs advantaged levels of social determinants of health (SDOH).

Methods: In this ecological analysis, we used the National HIV Surveillance System data in 2021 and SDOH data from 2017-2021 American Community Survey. We measured racial and ethnic disparities stratified by sex in the most disadvantaged quartiles and advantaged quartiles for: 1) Poverty 2) Education level 3) Median household income and 4) Insurance coverage.

Disparities in hepatitis C among people aged 12-59 with no history of injection drug use, United States, January 2013-March 2020.

Background And Aims: In the United States, hepatitis C virus (HCV) infection occurs primarily through injection drug use (IDU), but transmission also occurs through other ways. This study examined HCV prevalence and disparities among US residents aged 12-59 years with no IDU history.

Methods: We analysed 2013-March 2020 National Health and Nutrition Examination Survey data to calculate the HCV prevalence among people with no drug use history and only a non-IDU history, collectively referred to as no IDU history.

Tuberculosis and Chronic Hepatitis B Virus Infection Screening Among Non-US-Born Persons in an Integrated Health System in California.

Background: Tuberculosis infection (TBI) and chronic hepatitis B virus (HBV) infection disproportionately affect non-US-born persons. Early identification and treatment are critical to reduce transmission, morbidity, and mortality, but little is known about screening in the United States.

Methods: We conducted a cross-sectional study in a large integrated California health system in September 2022 assessing TBI and HBV screening among persons aged ≥18 years who were born in countries with high TB burden (TB disease incidence rates ≥20/100 000 population) and/or HBV burden (hepatitis B surface antigen seroprevalence >2%).

Estimated Health and Economic Outcomes of Racial and Ethnic Tuberculosis Disparities in US-Born Persons.

Importance: Despite significant progress made toward tuberculosis (TB) elimination, racial and ethnic disparities persist in TB incidence and case-fatality rates in the US.

Objective: To estimate the health outcomes and economic cost of TB disparities among US-born persons from 2023 to 2035.

Design, Setting, And Participants: Generalized additive regression models projecting trends in TB incidence and case-fatality rates from 2023 to 2035 were fit based on national TB surveillance data for 2010 to 2019 in the 50 US states and the District of Columbia among US-born persons.
