Artemisinin partial resistance, driven by Plasmodium falciparum K13 mutations, threatens malaria control. Zanzibar is vulnerable to artemisinin partial resistance spread but lacks recent molecular surveillance. We sequenced samples in Zanzibar and mainland Tanzania collected from 2022 to 2024. K13 mutations were found in 2 of 1440 participants (P441L, A675V) in Zanzibar and 6 of 3762 (R561H, P441L) in mainland Tanzania. Based on whole genome sequencing data, K13 mutations appear to be of African origin with regional spread. Frequent parasite importation appears to maintain partner drug mutation frequencies similar to the mainland, where artemether-lumefantrine selects for mutations favoring artesunate-amodiaquine sensitivity.

Dynamical Analysis Of A Stochastic $Sei_{U}I_{R}Rs$ Epidemic Model With Vaccination And Log-Normal Ornstein-Uhlenbeck Process, Qun Liu Feb 2026

Dynamical Analysis Of A Stochastic $Sei_{U}I_{R}Rs$ Epidemic Model With Vaccination And Log-Normal Ornstein-Uhlenbeck Process, Qun Liu

Faculty Publications

In this study, we develop and investigate a stochastic $SEI_{u}I_{r}RS$ (Susceptible-Exposed-Undetected infected-Detected infected-Recovered-Susceptible) epidemic model with vaccination of newborns and the disease transmission rate driven by a log-normal Ornstein-Uhlenbeck process. By establishing a series of Lyapunov functions, we derive sufficient conditions for persistence in the mean of the disease in the long term under the condition $\mathcal{R}_{0}>1$ and these criteria are applied to guarantee the existence of an invariant probability measure of the stochastic system. Subsequently, we also derive sufficient conditions for eradication of the disease when the parameters $\mathcal{R}_{0}< 1$ and $\mathcal{R}_{0}^{E}< 1$. Finally, two numerical examples are given to confirm the theoretical results. This work can help us implement interventions to regulate the disease dynamics.

The glomerular filtration barrier poses a significant challenge for circulating proteins, with molecules below ~60–70 kDa facing rapid renal clearance. Endogenous proteins have evolved sophisticated evasion mechanisms including oligomerization, carrier binding, electrostatic repulsion, and FcRn-mediated recycling. Understanding these natural strategies provides blueprints for engineering therapeutic proteins with improved pharmacokinetics. This review examines how endogenous proteins resist filtration, evaluates their application in protein engineering, and discusses clinical translation including established technologies (PEGylation, Fc-fusion) and emerging strategies (albumin-binding domains, glycoengineering). We address critical challenges of balancing half-life extension with tissue penetration, biological activity, and immunogenicity—essential considerations for the rational design of next-generation …

Background

To maintain HIV care during the COVID-19 pandemic, many HIV clinics across the United States adopted telehealth. However, not everyone participated in telehealth equally. This study assessed the use and disparities in telehealth and in-person HIV care at a large academic medical center in North Carolina (NC) relative to the COVID-19 pandemic.

Methods

Data from the Duke University Infectious Disease clinic in NC were extracted from electronic health records (EHR), aggregated across persons with HIV (PWH) by calendar month, visit type (in-person vs. telehealth HIV care), and by key sociodemographic and clinical characteristics. Variation in HIV care over time …

Objective: Youth are at high risk for HIV, accounting for 19% of new diagnoses in the United States (US) in 2021. Highly effective HIV treatment is available in the form of antiretroviral therapy (ART), which enables individuals with HIV to achieve viral suppression. However, youth living with HIV (YLHIV) have poorer ART adherence and lower rates of viral suppression than adults. This study aimed to explore the perspectives of YLHIV and their HIV care providers on barriers and facilitators to ART adherence for YLHIV in the southern US. Methods: Semi-structured qualitative interviews were conducted with YLHIV (n = 16) …


Compensating Regulatory Losers, Todd S. Aagaard Apr 2025

Compensating Regulatory Losers, Todd S. Aagaard

Faculty Publications

Every change in government regulation creates benefits and burdens that fall unequally on the population. This unequal distribution raises the question of whether fairness requires compensating those who bear regulatory costs—what is known as the “compensation problem.” The extensive body of scholarship addressing the compensation problem tends to focus only on the burdens of regulatory compliance and ignores the burdens of injuries left unaddressed by regulation. The effect of this differential treatment is to treat past regulatory windfalls as permanent entitlements and to omit from the analysis equally deserving regulatory losers who have suffered the consequences of unregulated harms. This …


Evergreening's Empirical Chasm, Erika Lietzan Jan 2025

Evergreening's Empirical Chasm, Erika Lietzan

Faculty Publications

For more than two decades, policymakers have been told that pharmaceutical innovators companies engage in a practice that is called, disparagingly, “evergreening.” The basic idea is that companies introduce new versions of their drugs that have later expiring patents or regulatory exclusivity. This way, the claim goes, the companies effectively block generic entry for years or decades longer than Congress intended and than is socially desirable. Initially these claims were supported by poorly researched anecdotes. In the last decade, some scholars and advocacy organizations have published papers that purport to provide empirical support for the “evergreening” accusation. But these empirical …
