Clinical rebound after treatment with nirmatrelvir/ritonavir in COVID-19.

Background: Nirmatrelvir/ritonavir (NM/r) is a safe and effective oral antiviral therapeutic used for treatment of mild-to-moderate COVID-19. Case reports described a clinical rebound syndrome whereby individuals experience a relapse of symptoms shortly after completing successful treatment. There is a lack of information on frequency of COVID-19 rebound after NM/r in routine clinical care, contributing factors, and clinical outcomes.

Pre-implementation planning to enhance integration of HIV and behavioral health care services at two Ryan White-funded HIV care centers.

Behavioral health conditions are disproportionately experienced by people living with Human immunodeficiency virus (HIV), including young Black gay, bisexual, and other men who have sex with men (GBMSM). Left unaddressed, these symptoms can adversely impact HIV care outcomes. Improving the integration of behavioral health and HIV care services has been proposed as a strategy to address this challenge.

Incidence and risk factors of SARS-CoV-2 breakthrough infection in the early Omicron variant era among vaccinated and boosted individuals in Chicago.

Background: SARS-CoV-2 vaccines are safe and effective against infection and severe COVID-19 disease worldwide. Certain co-morbid conditions cause immune dysfunction and may reduce immune response to vaccination. In contrast, those with co-morbidities may practice infection prevention strategies.

The actin binding sites of talin have both distinct and complementary roles in cell-ECM adhesion.

Cell adhesion requires linkage of transmembrane receptors to the cytoskeleton through intermediary linker proteins. Integrin-based adhesion to the extracellular matrix (ECM) involves large adhesion complexes that contain multiple cytoskeletal adapters that connect to the actin cytoskeleton. Many of these adapters, including the essential cytoskeletal linker Talin, have been shown to contain multiple actin-binding sites (ABSs) within a single protein.
