Alcohol-associated hepatitis trends before and following the onset of the COVID-19 pandemic across two distinct cohorts in the United States and Hong Kong.

Background & Aims: Alcohol-associated liver disease (ALD) burden has been rising globally, fueled by increases in high-risk alcohol use following the coronavirus disease 2019 (COVID-19) pandemic. We evaluated trends in annual incidence of alcohol-associated hepatitis (AH) before and following the onset of the COVID-19 pandemic across two geographically distinct populations in the USA and Hong Kong.

Methods: Using US national Veterans Affairs (VA) data and Hong Kong territory-wide data, trends in annual incidence of AH were evaluated from 2000 to 2023.

One-Pot and Gram-Scale Synthesis of Fe-Based Nanozymes with Tunable O Activation Pathway and Specificity Between Associated Enzymatic Reactions.

Nanozymes have recently gained attention for their low cost and high stability. However, unlike natural enzymes, they often exhibit multiple enzyme-like activities, complicating their use in selective bioassays. Since HO and O are common substrates in these reactions, controlling their activation-and thus reaction specificity-is crucial.

Clinical validation of MR-generated synthetic CT by MRCAT for brain tumor radiotherapy.

Objective: MRI is an emerging modality in radiotherapy (RT). Accuracy synthetic CT is the prerequisite for implementing MR-only RT planning. This study validated the commercial algorithm of MR for calculating attenuation (MRCAT) in terms of image quality and dosimetric agreement.

Impact of daily neighborhood crime on nightly sleep among adolescents.

Crime impacts both the immediate victims and has indirect effects on the community. This study examined associations between daily neighborhood crime and actigraphy-assessed sleep outcomes using multilevel modeling. Data were from a longitudinal (14-day) study of 288 adolescents (M = 15.
