Background: Neuregulin (NRG) family is involved in energy metabolism, among which NRG1 is a neuregulin proved to play a protective role in MAFLD cells. But the presice echanism has not been fully illustrated. This study aimed to investigate the role of NRG1 via the ERK/SIRT1 signaling in the pathogenesis of MAFLD.

Remimazolam (Byfavo, Acacia Pharma), a recent Food and Drug Administration-approved ester-linked benzodiazepine, offers advantages in sedation, such as rapid onset and predictable duration, making it suitable for broad anesthesia applications. Its favorable pharmacological profile is primarily attributed to rapid hydrolysis, the primary metabolism pathway for its deactivation. Thus, understanding remimazolam hydrolysis determinants is essential for optimizing its clinical use.

Several clinical studies have shown that COVID-19 increases the systemic concentration of drugs in hospitalized patients with COVID-19. However, it is unclear how COVID-19-mediated bidirectional dysregulation of hepatic and pulmonary cytochrome P450 (CYP) 3A4 affects drug concentrations, especially in the lung tissue, which is most affected by the disease. Herein, physiologically based pharmacokinetic modeling was used to demonstrate the differences in systemic and pulmonary concentrations of 4 respiratory infectious disease drugs when CYP3A4 is concurrently downregulated in the liver and upregulated in the lung based on existing clinical data on COVID-19-CYP3A4 interactions at varying severity levels including outpatients, non-intensive care unit (ICU), and ICU patients.

Background: Viremia has been detected in a significant proportion of patients with acute respiratory viral infection, yet its clinical value remains underappreciated.
Objectives: This study synthesized available evidence to comprehensively assess the prevalence of viremia and its impact on clinical outcomes.
Data Sources: Data were retrieved from Medline (via Ovid), Embase, and the WHO COVID-19 database.
