Political determinants of US states' screening-amenable cancer stage at diagnosis and premature cancer mortality.

Background: Political determinants of cancer risk are largely unexplored, conceptually and empirically.

Methods: Observational analysis of associations present in 2017-2021 between 5 state-level political metrics and 4 age-standardized cancer outcomes (regional and distant stage at diagnosis for breast, cervical, and colorectal cancer among screening-age adults and premature cancer mortality), overall and in standardized linear regression models adjusting for state-level poverty and medical uninsurance.

Results: In fully adjusted models (adjusted for state-level poverty and state-level medical uninsurance variables: % working age adults [age 35-64] without medical insurance; number of years of state Medicaid expansion), each 1 SD shift toward a more liberal political ideology (measured by voting record) among elected officials in the US House of Representatives was associated with decreased risk of diagnosis with regional and distant breast and colorectal cancer (respectively: -0.

Advancing health equity in wastewater-based epidemiology: A global critical review and conceptual framework.

Population health data from wastewater-based epidemiology (WBE) are being used at unprecedented scales worldwide, yet there is limited focus on how to advance health equity in the field. Addressing this gap, we conducted a critical review of published literature in PubMed, targeting studies at the intersection of WBE and health equity. Of 145 articles assessed in full-text screening, we identified 68 studies with health equity considerations.

Politicians, power, and the people's health: US elections and state health outcomes, 2012-2024.

Our descriptive study examined current associations (2022-2024) between US state-level health outcomes and 4 US state-level political metrics: 2 rarely used in public health research (political ideology of elected representatives based on voting records; trifectas, where 1 party controls the executive and legislative branches) and 2 more commonly used (state policies enacted; voter political lean). The 8 health outcomes spanned the life course: infant mortality, premature mortality (death at age <65), health insurance (adults aged 35-64), vaccination for children and persons aged ≥65 (flu; COVID-19 booster), maternity care deserts, and food insecurity. For the first 3 outcomes, we also examined trends in associations (2012-2024).

Visualizing Neighborhood COVID-19 Levels, Trends, and Inequities in Wastewater: An Equity-Centered Approach and Comparison to CDC Methods.

Context: Monitoring neighborhood-level SARS-CoV-2 wastewater concentrations can help guide public health interventions and provide early warning ahead of lagging COVID-19 clinical indicators. To date, however, U.S.

Modeling the impact of universal tuberculosis molecular testing and timing of tuberculosis preventive treatment during antiretroviral therapy initiation in South Africa.

Objectives: Targeted universal tuberculosis (TB) testing can improve TB detection among people with HIV. This approach is being scaled up in South Africa through Xpert MTB/RIF Ultra testing for individuals starting antiretroviral therapy and annually thereafter. Clarity is needed on how Universal Xpert testing may affect TB preventive treatment (TPT) provision, and on whether TPT should be delayed until TB is ruled out.

Global incidence in hospital-associated infections resistant to antibiotics: An analysis of point prevalence surveys from 99 countries.

Background: Hospital-associated infections (HAIs) are an important cause of morbidity and mortality around the world. Many HAIs are caused by drug-resistant bacterial pathogens, but there are major gaps in our understanding of the number of hospital-associated drug-resistant infections (HARIs) worldwide. As such, we estimated trends in prevalence of HARIs caused by high priority pathogens (Escherichia coli, Acinetobacter spp.

SARS-CoV-2 testing strategies for outbreak mitigation in vaccinated populations.

Although COVID-19 vaccines are globally available, waning immunity and emerging vaccine-evasive variants of concern have hindered the international response and transition to a post-pandemic era. Testing to identify and isolate infectious individuals remains the most proactive strategy for containing an ongoing COVID-19 outbreak. We developed a stochastic, compartmentalized model to simulate the impact of using Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) assays, rapid antigen tests, and vaccinations on SARS-CoV-2 spread.

Projected Impact of Expanded Long-Acting Injectable PrEP Use Among Men Who Have Sex With Men on Local HIV Epidemics.

Background: Pre-exposure prophylaxis (PrEP) is a key component in helping to reduce HIV incidence in the United States. Long-acting injectable (LAI) PrEP is a new alternative to oral PrEP; its potential to affect local HIV epidemics remains unclear.

Methods: The Johns Hopkins HIV Economic Epidemiological model (JHEEM) is a dynamic model of HIV transmission in 32 US urban areas.

The epidemiology of dengue outbreaks in 2016 and 2017 in Ouagadougou, Burkina Faso.

Background: Dengue is prevalent in as many as 128 countries with more than 100 million clinical episodes reported annually and four billion people estimated to be at risk. While dengue fever is systematically diagnosed in large parts of Asia and South America, the disease burden in Africa is less well investigated. This report describes two consecutive dengue outbreaks in Ouagadougou, Burkina Faso in 2016 and 2017.

The global burden and epidemiology of invasive non-typhoidal infections.

Invasive non-typhoidal (iNTS) disease has emerged as a major public health concern. Yet, understanding of the global burden is incomplete, limited particularly by the breadth of blood culture-based surveillance systems that are able to accurately diagnose the etiology of bacteremia. The accessibility of whole genome sequencing has allowed for genetic characterization of pathogens, shedding light on its evolutionary history and sounding alerts for its future progression.
