Policy Challenges and Resiliency Related to Ending the HIV Epidemic in the Southern and Rural United States: A Call to Action.

ABSTRACT: In this commentary, we describe current policy trends and their implications for the health of populations in the Southern and rural United States. We outline policy changes that threaten the prevention, care, and treatment of people at risk for HIV or with HIV and sociopolitical factors contributing to these policy trends. We also issue a call-to-action for individuals with Southern and rural US policy expertise and lived or living experience to collaboratively engage on a systematic policy analysis to thoroughly document relevant policies and deepen our understanding of the influences behind these policies. Finally, we provide examples of individual, community, and national level resiliency and courage-strategies that inspire advocacy and hope in the face of policy setbacks.

Extracellular Vesicles in Viral Replication and Pathogenesis and Their Potential Role in Therapeutic Intervention.

Extracellular vesicles (EVs) have shown their potential as a carrier of molecular information, and they have been involved in physiological functions and diseases caused by viral infections. Virus-infected cells secrete various lipid-bound vesicles, including endosome pathway-derived exosomes and microvesicles/microparticles that are released from the plasma membrane. They are released via a direct outward budding and fission of plasma membrane blebs into the extracellular space to either facilitate virus propagation or regulate the immune responses. Moreover, EVs generated by virus-infected cells can incorporate virulence factors including viral protein and viral genetic material, and thus can resemble noninfectious viruses. Interactions of EVs with recipient cells have been shown to activate signaling pathways that may contribute to a sustained cellular response towards viral infections. EVs, by utilizing a complex set of cargos, can play a regulatory role in viral infection, both by facilitating and suppressing the infection. EV-based antiviral and antiretroviral drug delivery approaches provide an opportunity for targeted drug delivery. In this review, we summarize the literature on EVs, their associated involvement in transmission in viral infections, and potential therapeutic implications.

Risk of Anal Cancer in People Living with HIV: Addressing Anal Health in the HIV Primary Care Setting.

Anal health and anal cancer are rarely addressed in HIV primary care. We sought to understand factors that impeded or promoted addressing anal health in HIV primary care from providers' perspectives. In this exploratory study, HIV primary care providers from the Mid-South region of the United States participated in brief individual interviews. We analyzed transcribed data to identify barriers and facilitators to addressing anal health. Our study sample included five physicians and four nurse practitioners. The data revealed a number of barriers such as perception of patient embarrassment, provider embarrassment, external issues such as time constraints, demand of other priorities, lack of anal complaints, lack of resources, and gender discordance. Facilitators included awareness, advantageous circumstances, and the patient-provider relationship. Anal health education should be prioritized for HIV primary care providers. Preventive health visits should be considered to mitigate time constraints, demands for other priorities, and unequal gender opportunities.
